+ 0 means the device will be autosuspended as soon as

+KernelVersion: 2.6.21
+Contact: Alan Stern <stern@rowland.harvard.edu>
+Description:
+ Each USB device directory will contain a file named
+ power/level. This file holds a power-level setting for
+ the device, one of "on", "auto", or "suspend".
+
+ "on" means that the device is not allowed to autosuspend,
+ although normal suspends for system sleep will still
+ be honored. "auto" means the device will autosuspend
+ and autoresume in the usual manner, according to the
+ capabilities of its driver. "suspend" means the device
+ is forced into a suspended state and it will not autoresume
+ in response to I/O requests. However remote-wakeup requests
+ from the device may still be enabled (the remote-wakeup
+ setting is controlled separately by the power/wakeup
+ attribute).
+
+ During normal use, devices should be left in the "auto"
+ level. The other levels are meant for administrative uses.
+ If you want to suspend a device immediately but leave it
+ free to wake up in response to I/O requests, you should
+ write "0" to power/autosuspend.

+ embedded systems because it is a simple and efficient
+ interface: basically a multiplexed shift register.
+ Its three signal wires hold a clock (SCK, often in the range
+ of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
+ a "Master In, Slave Out" (MISO) data line.
+ SPI is a full duplex protocol; for each bit shifted out the
+ MOSI line (one per clock) another is shifted in on the MISO line.
+ Those bits are assembled into words of various sizes on the
+ way to and from system memory.
+ An additional chipselect line is usually active-low (nCS);
+ four signals are normally used for each peripheral, plus
+ sometimes an interrupt.
+ </para>
+ <para>
+ The SPI bus facilities listed here provide a generalized
+ interface to declare SPI busses and devices, manage them
+ according to the standard Linux driver model, and perform
+ input/output operations.
+ At this time, only "master" side interfaces are supported,
+ where Linux talks to SPI peripherals and does not implement
+ such a peripheral itself.
+ (Interfaces to support implementing SPI slaves would
+ necessarily look different.)
+ </para>
+ <para>
+ The programming interface is structured around two kinds of driver,
+ and two kinds of device.
+ A "Controller Driver" abstracts the controller hardware, which may
+ be as simple as a set of GPIO pins or as complex as a pair of FIFOs
+ connected to dual DMA engines on the other side of the SPI shift
+ register (maximizing throughput). Such drivers bridge between
+ whatever bus they sit on (often the platform bus) and SPI, and
+ expose the SPI side of their device as a
+ <structname>struct spi_master</structname>.
+ SPI devices are children of that master, represented as a
+ <structname>struct spi_device</structname> and manufactured from
+ <structname>struct spi_board_info</structname> descriptors which
+ are usually provided by board-specific initialization code.
+ A <structname>struct spi_driver</structname> is called a
+ "Protocol Driver", and is bound to a spi_device using normal
+ driver model calls.
+ </para>
+ <para>
+ The I/O model is a set of queued messages. Protocol drivers
+ submit one or more <structname>struct spi_message</structname>
+ objects, which are processed and completed asynchronously.
+ (There are synchronous wrappers, however.) Messages are
+ built from one or more <structname>struct spi_transfer</structname>
+ objects, each of which wraps a full duplex SPI transfer.
+ A variety of protocol tweaking options are needed, because
+ different chips adopt very different policies for how they
+ use the bits transferred with SPI.

+ How to mount the root file system in uClinux/Blackfin
+ -----------------------------------------------------
+
+1 Mounting EXT3 File system.
+ ------------------------
+
+ Creating an EXT3 File system for uClinux/Blackfin:
+
+
+Please follow the steps to form the EXT3 File system and mount the same as root
+file system.
+
+a Make an ext3 file system as large as you want the final root file
+ system.
+
+ mkfs.ext3 /dev/ram0 <your-rootfs-size-in-1k-blocks>
+
+b Mount this Empty file system on a free directory as:
+
+ mount -t ext3 /dev/ram0 ./test
+ where ./test is the empty directory.
+
+c Copy your root fs directory that you have so carefully made over.
+
+ cp -af /tmp/my_final_rootfs_files/* ./test
+
+ (For ex: cp -af uClinux-dist/romfs/* ./test)
+
+d If you have done everything right till now you should be able to see
+ the required "root" dir's (that's etc, root, bin, lib, sbin...)
+
+e Now unmount the file system
+
+ umount ./test
+
+f Create the root file system image.
+
+ dd if=/dev/ram0 bs=1k count=<your-rootfs-size-in-1k-blocks> \
+ > ext3fs.img
+
+
+Now you have to tell the kernel that will be mounting this file system as
+rootfs.
+So do a make menuconfig under kernel and select the Ext3 journaling file system
+support under File system --> submenu.
+
+
+2. Mounting EXT2 File system.
+ -------------------------
+
+By default the ext2 file system image will be created if you invoke make from
+the top uClinux-dist directory.
+
+
+3. Mounting CRAMFS File System
+ ----------------------------
+
+To create a CRAMFS file system image execute the command
+
+ mkfs.cramfs ./test cramfs.img
+
+ where ./test is the target directory.
+
+
+4. Mounting ROMFS File System
+ --------------------------
+
+To create a ROMFS file system image execute the command
+
+ genromfs -v -V "ROMdisk" -f romfs.img -d ./test
+
+ where ./test is the target directory
+
+
+5. Mounting the JFFS2 Filesystem
+ -----------------------------
+
+To create a compressed JFFS filesystem (JFFS2), please execute the command
+
+ mkfs.jffs2 -d ./test -o jffs2.img
+
+ where ./test is the target directory.
+
+However, please make sure the following is in your kernel config.
+
+/*
+ * RAM/ROM/Flash chip drivers
+ */
+#define CONFIG_MTD_CFI 1
+#define CONFIG_MTD_ROM 1
+/*
+ * Mapping drivers for chip access
+ */
+#define CONFIG_MTD_COMPLEX_MAPPINGS 1
+#define CONFIG_MTD_BF533 1
+#undef CONFIG_MTD_UCLINUX
+
+Through the u-boot boot loader, use the jffs2.img in the corresponding
+partition made in linux-2.6.x/drivers/mtd/maps/bf533_flash.c.
+
+NOTE - Currently the Flash driver is available only for EZKIT. Watch out for a
+ STAMP driver soon.
+
+
+6. Mounting the NFS File system
+ -----------------------------
+
+ For mounting the NFS please do the following in the kernel config.
+
+ In Networking Support --> Networking options --> TCP/IP networking -->
+ IP: kernel level autoconfiguration
+
+ Enable BOOTP Support.
+
+ In Kernel hacking --> Compiled-in kernel boot parameter add the following
+
+ root=/dev/nfs rw ip=bootp
+
+ In File system --> Network File system, Enable
+
+ NFS file system support --> NFSv3 client support
+ Root File system on NFS
+
+ in uClibc menuconfig, do the following
+ In Networking Support
+ enable Remote Procedure Call (RPC) support
+ Full RPC Support
+
+ On the Host side, ensure that /etc/dhcpd.conf looks something like this
+
+ ddns-update-style ad-hoc;
+ allow bootp;
+ subnet 10.100.4.0 netmask 255.255.255.0 {
+ default-lease-time 122209600;
+ max-lease-time 31557600;
+ group {
+ host bf533 {
+ hardware ethernet 00:CF:52:49:C3:01;
+ fixed-address 10.100.4.50;
+ option root-path "/home/nfsmount";
+ }
+ }
+
+ ensure that /etc/exports looks something like this
+ /home/nfsmount *(rw,no_root_squash,no_all_squash)
+
+ run the following commands as root (may differ depending on your
+ distribution) :
+ - service nfs start
+ - service portmap start
+ - service dhcpd start
+ - /usr/sbin/exportfs

+How to lock your code in cache in uClinux/blackfin
+--------------------------------------------------
+
+There are only a few steps required to lock your code into the cache.
+Currently you can lock the code by Way.
+
+Below are the interface provided for locking the cache.
+
+
+1. cache_grab_lock(int Ways);
+
+This function grab the lock for locking your code into the cache specified
+by Ways.
+
+
+2. cache_lock(int Ways);
+
+This function should be called after your critical code has been executed.
+Once the critical code exits, the code is now loaded into the cache. This
+function locks the code into the cache.
+
+
+So, the example sequence will be:
+
+ cache_grab_lock(WAY0_L); /* Grab the lock */
+
+ critical_code(); /* Execute the code of interest */
+
+ cache_lock(WAY0_L); /* Lock the cache */
+
+Where WAY0_L signifies WAY0 locking.

+Supported Hardware
+==================
+
+ ARK 2000PV chip
+ ICS 5342 ramdac
+
+ - only BIOS initialized VGA devices supported
+ - probably not working on big endian
+
+
+Supported Features
+==================
+
+ * 4 bpp pseudocolor modes (with 18bit palette, two variants)
+ * 8 bpp pseudocolor mode (with 18bit palette)
+ * 16 bpp truecolor modes (RGB 555 and RGB 565)

+ * 32 bpp truecolor mode (RGB 888)
+ * text mode (activated by bpp = 0)
+ * doublescan mode variant (not available in text mode)
+ * panning in both directions
+ * suspend/resume support
+
+Text mode is supported even in higher resolutions, but there is limitation to
+lower pixclocks (i got maximum about 70 MHz, it is dependent on specific
+hardware). This limitation is not enforced by driver. Text mode supports 8bit
+wide fonts only (hardware limitation) and 16bit tall fonts (driver
+limitation). Unfortunately character attributes (like color) in text mode are
+broken for unknown reason, so its usefulness is limited.
+
+There are two 4 bpp modes. First mode (selected if nonstd == 0) is mode with
+packed pixels, high nibble first. Second mode (selected if nonstd == 1) is mode
+with interleaved planes (1 byte interleave), MSB first. Both modes support
+8bit wide fonts only (driver limitation).
+
+Suspend/resume works on systems that initialize video card during resume and
+if device is active (for example used by fbcon).

+Deferred IO
+-----------
+
+Deferred IO is a way to delay and repurpose IO. It uses host memory as a
+buffer and the MMU pagefault as a pretrigger for when to perform the device
+IO. The following example may be a useful explaination of how one such setup
+works:
+
+- userspace app like Xfbdev mmaps framebuffer
+- deferred IO and driver sets up nopage and page_mkwrite handlers
+- userspace app tries to write to mmaped vaddress
+- we get pagefault and reach nopage handler
+- nopage handler finds and returns physical page
+- we get page_mkwrite where we add this page to a list
+- schedule a workqueue task to be run after a delay
+- app continues writing to that page with no additional cost. this is
+ the key benefit.
+- the workqueue task comes in and mkcleans the pages on the list, then
+ completes the work associated with updating the framebuffer. this is
+ the real work talking to the device.
+- app tries to write to the address (that has now been mkcleaned)
+- get pagefault and the above sequence occurs again
+
+As can be seen from above, one benefit is roughly to allow bursty framebuffer
+writes to occur at minimum cost. Then after some time when hopefully things
+have gone quiet, we go and really update the framebuffer which would be
+a relatively more expensive operation.
+
+For some types of nonvolatile high latency displays, the desired image is
+the final image rather than the intermediate stages which is why it's okay
+to not update for each write that is occuring.
+
+It may be the case that this is useful in other scenarios as well. Paul Mundt
+has mentioned a case where it is beneficial to use the page count to decide
+whether to coalesce and issue SG DMA or to do memory bursts.
+
+Another one may be if one has a device framebuffer that is in an usual format,
+say diagonally shifting RGB, this may then be a mechanism for you to allow
+apps to pretend to have a normal framebuffer but reswizzle for the device
+framebuffer at vsync time based on the touched pagelist.
+
+How to use it: (for applications)
+---------------------------------
+No changes needed. mmap the framebuffer like normal and just use it.
+
+How to use it: (for fbdev drivers)
+----------------------------------
+The following example may be helpful.
+
+1. Setup your structure. Eg:
+
+static struct fb_deferred_io hecubafb_defio = {
+ .delay = HZ,
+ .deferred_io = hecubafb_dpy_deferred_io,
+};
+
+The delay is the minimum delay between when the page_mkwrite trigger occurs
+and when the deferred_io callback is called. The deferred_io callback is
+explained below.
+
+2. Setup your deferred IO callback. Eg:
+static void hecubafb_dpy_deferred_io(struct fb_info *info,
+ struct list_head *pagelist)
+
+The deferred_io callback is where you would perform all your IO to the display
+device. You receive the pagelist which is the list of pages that were written
+to during the delay. You must not modify this list. This callback is called
+from a workqueue.
+
+3. Call init
+ info->fbdefio = &hecubafb_defio;
+ fb_deferred_io_init(info);
+
+4. Call cleanup
+ fb_deferred_io_cleanup(info);

- (*) Other objects can't be looked up inside of them. This also incurs an

+Manually unmounting an AFS volume will cause any idle submounts upon it to be
+culled first. If all are culled, then the requested volume will also be
+unmounted, otherwise error EBUSY will be returned.

+SECURITY
+========
+
+Secure operations are initiated by acquiring a key using the klog program. A
+very primitive klog program is available at:
+
+ http://people.redhat.com/~dhowells/rxrpc/klog.c
+
+This should be compiled by:
+
+ make klog LDLIBS="-lcrypto -lcrypt -lkrb4 -lkeyutils"
+
+And then run as:
+
+ ./klog
+
+Assuming it's successful, this adds a key of type RxRPC, named for the service
+and cell, eg: "afs@<cellname>". This can be viewed with the keyctl program or
+by cat'ing /proc/keys:
+
+ [root@andromeda ~]# keyctl show
+ Session Keyring
+ -3 --alswrv 0 0 keyring: _ses.3268
+ 2 --alswrv 0 0 \_ keyring: _uid.0
+ 111416553 --als--v 0 0 \_ rxrpc: afs@CAMBRIDGE.REDHAT.COM
+
+Currently the username, realm, password and proposed ticket lifetime are
+compiled in to the program.
+
+It is not required to acquire a key before using AFS facilities, but if one is
+not acquired then all operations will be governed by the anonymous user parts
+of the ACLs.
+
+If a key is acquired, then all AFS operations, including mounts and automounts,
+made by a possessor of that key will be secured with that key.
+
+If a file is opened with a particular key and then the file descriptor is
+passed to a process that doesn't have that key (perhaps over an AF_UNIX
+socket), then the operations on the file will be made with key that was used to
+open the file.

+Description
+-----------
+
+This driver permits reading temperature sensor embedded inside Intel Core CPU.
+Temperature is measured in degrees Celsius and measurement resolution is
+1 degree C. Valid temperatures are from 0 to TjMax degrees C, because
+the actual value of temperature register is in fact a delta from TjMax.
+
+Temperature known as TjMax is the maximum junction temperature of processor.
+Intel defines this temperature as 85C or 100C. At this temperature, protection
+mechanism will perform actions to forcibly cool down the processor. Alarm
+may be raised, if the temperature grows enough (more than TjMax) to trigger
+the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
+
+temp1_input - Core temperature (in millidegrees Celsius).
+temp1_crit - Maximum junction temperature (in millidegrees Celsius).
+temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
+ Correct CPU operation is no longer guaranteed.
+temp1_label - Contains string "Core X", where X is processor
+ number.
+
+The TjMax temperature is set to 85 degrees C if undocumented model specific
+register (UMSR) 0xee has bit 30 set. If not the TjMax is 100 degrees C as
+(sometimes) documented in processor datasheet.

+Description
+-----------
+
+This driver implements support for the Maxim 6650/6651
+
+The 2 devices are very similar, but the Maxim 6550 has a reduced feature
+set, e.g. only one fan-input, instead of 4 for the 6651.
+
+The driver is not able to distinguish between the 2 devices.
+
+The driver provides the following sensor accesses in sysfs:
+
+fan1_input ro fan tachometer speed in RPM
+fan2_input ro "
+fan3_input ro "
+fan4_input ro "
+fan1_target rw desired fan speed in RPM (closed loop mode only)
+pwm1_enable rw regulator mode, 0=full on, 1=open loop, 2=closed loop
+pwm1 rw relative speed (0-255), 255=max. speed.
+ Used in open loop mode only.
+fan1_div rw sets the speed range the inputs can handle. Legal
+ values are 1, 2, 4, and 8. Use lower values for
+ faster fans.
+
+Module parameters
+-----------------
+
+If your board has a BIOS that initializes the MAX6650/6651 correctly, you can
+simply load your module without parameters. It won't touch the configuration
+registers then. If your board BIOS doesn't initialize the chip, or you want
+different settings, you can set the following parameters:
+
+voltage_12V: 5=5V fan, 12=12V fan, 0=don't change
+prescaler: Possible values are 1,2,4,8,16, or 0 for don't change
+clock: The clock frequency in Hz of the chip the driver should assume [254000]
+
+Please have a look at the MAX6650/6651 data sheet and make sure that you fully
+understand the meaning of these parameters before you attempt to change them.

Probing and attaching
=====================
+The Linux I2C stack was originally written to support access to hardware
+monitoring chips on PC motherboards, and thus it embeds some assumptions
+that are more appropriate to SMBus (and PCs) than to I2C. One of these
+assumptions is that most adapters and devices drivers support the SMBUS_QUICK
+protocol to probe device presence. Another is that devices and their drivers
+can be sufficiently configured using only such probe primitives.
+
+As Linux and its I2C stack became more widely used in embedded systems
+and complex components such as DVB adapters, those assumptions became more
+problematic. Drivers for I2C devices that issue interrupts need more (and
+different) configuration information, as do drivers handling chip variants
+that can't be distinguished by protocol probing, or which need some board
+specific information to operate correctly.
+
+Accordingly, the I2C stack now has two models for associating I2C devices
+with their drivers: the original "legacy" model, and a newer one that's
+fully compatible with the Linux 2.6 driver model. These models do not mix,
+since the "legacy" model requires drivers to create "i2c_client" device
+objects after SMBus style probing, while the Linux driver model expects
+drivers to be given such device objects in their probe() routines.
+
+
+Standard Driver Model Binding ("New Style")
+-------------------------------------------
+
+System infrastructure, typically board-specific initialization code or
+boot firmware, reports what I2C devices exist. For example, there may be
+a table, in the kernel or from the boot loader, identifying I2C devices
+and linking them to board-specific configuration information about IRQs
+and other wiring artifacts, chip type, and so on. That could be used to
+create i2c_client objects for each I2C device.
+
+I2C device drivers using this binding model work just like any other
+kind of driver in Linux: they provide a probe() method to bind to
+those devices, and a remove() method to unbind.
+
+ static int foo_probe(struct i2c_client *client);
+ static int foo_remove(struct i2c_client *client);
+
+Remember that the i2c_driver does not create those client handles. The
+handle may be used during foo_probe(). If foo_probe() reports success
+(zero not a negative status code) it may save the handle and use it until
+foo_remove() returns. That binding model is used by most Linux drivers.
+
+Drivers match devices when i2c_client.driver_name and the driver name are
+the same; this approach is used in several other busses that don't have
+device typing support in the hardware. The driver and module name should
+match, so hotplug/coldplug mechanisms will modprobe the driver.
+
+
+Device Creation (Standard driver model)
+---------------------------------------
+
+If you know for a fact that an I2C device is connected to a given I2C bus,
+you can instantiate that device by simply filling an i2c_board_info
+structure with the device address and driver name, and calling
+i2c_new_device(). This will create the device, then the driver core will
+take care of finding the right driver and will call its probe() method.
+If a driver supports different device types, you can specify the type you
+want using the type field. You can also specify an IRQ and platform data
+if needed.
+
+Sometimes you know that a device is connected to a given I2C bus, but you
+don't know the exact address it uses. This happens on TV adapters for
+example, where the same driver supports dozens of slightly different
+models, and I2C device addresses change from one model to the next. In
+that case, you can use the i2c_new_probed_device() variant, which is
+similar to i2c_new_device(), except that it takes an additional list of
+possible I2C addresses to probe. A device is created for the first
+responsive address in the list. If you expect more than one device to be
+present in the address range, simply call i2c_new_probed_device() that
+many times.
+
+The call to i2c_new_device() or i2c_new_probed_device() typically happens
+in the I2C bus driver. You may want to save the returned i2c_client
+reference for later use.
+
+
+Device Deletion (Standard driver model)
+---------------------------------------
+
+Each I2C device which has been created using i2c_new_device() or
+i2c_new_probed_device() can be unregistered by calling
+i2c_unregister_device(). If you don't call it explicitly, it will be
+called automatically before the underlying I2C bus itself is removed, as a
+device can't survive its parent in the device driver model.
+
+
+Legacy Driver Binding Model
+---------------------------

Most i2c devices can be present on several i2c addresses; for some this
is determined in hardware (by soldering some chip pins to Vcc or Ground),

-The sensors sysctl/proc interface
-=================================
-
-This section only applies if you write `sensors' drivers.
-
-Each sensors driver creates a directory in /proc/sys/dev/sensors for each
-registered client. The directory is called something like foo-i2c-4-65.
-The sensors module helps you to do this as easily as possible.
-
-The template
-------------
-
-You will need to define a ctl_table template. This template will automatically
-be copied to a newly allocated structure and filled in where necessary when
-you call sensors_register_entry.
-
-First, I will give an example definition.
- static ctl_table foo_dir_table_template[] = {
- { FOO_SYSCTL_FUNC1, "func1", NULL, 0, 0644, NULL, &i2c_proc_real,
- &i2c_sysctl_real,NULL,&foo_func },
- { FOO_SYSCTL_FUNC2, "func2", NULL, 0, 0644, NULL, &i2c_proc_real,
- &i2c_sysctl_real,NULL,&foo_func },
- { FOO_SYSCTL_DATA, "data", NULL, 0, 0644, NULL, &i2c_proc_real,
- &i2c_sysctl_real,NULL,&foo_data },
- { 0 }
- };
-
-In the above example, three entries are defined. They can either be
-accessed through the /proc interface, in the /proc/sys/dev/sensors/*
-directories, as files named func1, func2 and data, or alternatively
-through the sysctl interface, in the appropriate table, with identifiers
-FOO_SYSCTL_FUNC1, FOO_SYSCTL_FUNC2 and FOO_SYSCTL_DATA.
-
-The third, sixth and ninth parameters should always be NULL, and the
-fourth should always be 0. The fifth is the mode of the /proc file;
-0644 is safe, as the file will be owned by root:root.
-
-The seventh and eighth parameters should be &i2c_proc_real and
-&i2c_sysctl_real if you want to export lists of reals (scaled
-integers). You can also use your own function for them, as usual.
-Finally, the last parameter is the call-back to gather the data
-(see below) if you use the *_proc_real functions.
-
-
-Gathering the data
-------------------
-
-The call back functions (foo_func and foo_data in the above example)
-can be called in several ways; the operation parameter determines
-what should be done:
-
- * If operation == SENSORS_PROC_REAL_INFO, you must return the
- magnitude (scaling) in nrels_mag;
- * If operation == SENSORS_PROC_REAL_READ, you must read information
- from the chip and return it in results. The number of integers
- to display should be put in nrels_mag;
- * If operation == SENSORS_PROC_REAL_WRITE, you must write the
- supplied information to the chip. nrels_mag will contain the number
- of integers, results the integers themselves.
-
-The *_proc_real functions will display the elements as reals for the
-/proc interface. If you set the magnitude to 2, and supply 345 for
-SENSORS_PROC_REAL_READ, it would display 3.45; and if the user would
-write 45.6 to the /proc file, it would be returned as 4560 for
-SENSORS_PROC_REAL_WRITE. A magnitude may even be negative!
-
-An example function:
-
- /* FOO_FROM_REG and FOO_TO_REG translate between scaled values and
- register values. Note the use of the read cache. */
- void foo_in(struct i2c_client *client, int operation, int ctl_name,
- int *nrels_mag, long *results)
- {
- struct foo_data *data = client->data;
- int nr = ctl_name - FOO_SYSCTL_FUNC1; /* reduce to 0 upwards */
-
- if (operation == SENSORS_PROC_REAL_INFO)
- *nrels_mag = 2;
- else if (operation == SENSORS_PROC_REAL_READ) {
- /* Update the readings cache (if necessary) */
- foo_update_client(client);
- /* Get the readings from the cache */
- results[0] = FOO_FROM_REG(data->foo_func_base[nr]);
- results[1] = FOO_FROM_REG(data->foo_func_more[nr]);
- results[2] = FOO_FROM_REG(data->foo_func_readonly[nr]);
- *nrels_mag = 2;
- } else if (operation == SENSORS_PROC_REAL_WRITE) {
- if (*nrels_mag >= 1) {

+IPF Machine Check (MC) error inject tool
+========================================
+
+IPF Machine Check (MC) error inject tool is used to inject MC
+errors from Linux. The tool is a test bed for IPF MC work flow including
+hardware correctable error handling, OS recoverable error handling, MC
+event logging, etc.
+
+The tool includes two parts: a kernel driver and a user application
+sample. The driver provides interface to PAL to inject error
+and query error injection capabilities. The driver code is in
+arch/ia64/kernel/err_inject.c. The application sample (shown below)
+provides a combination of various errors and calls the driver's interface
+(sysfs interface) to inject errors or query error injection capabilities.
+
+The tool can be used to test Intel IPF machine MC handling capabilities.
+It's especially useful for people who can not access hardware MC injection
+tool to inject error. It's also very useful to integrate with other
+software test suits to do stressful testing on IPF.
+
+Below is a sample application as part of the whole tool. The sample
+can be used as a working test tool. Or it can be expanded to include
+more features. It also can be a integrated into a libary or other user
+application to have more thorough test.
+
+The sample application takes err.conf as error configuation input. Gcc
+compiles the code. After you install err_inject driver, you can run
+this sample application to inject errors.
+
+Errata: Itanium 2 Processors Specification Update lists some errata against
+the pal_mc_error_inject PAL procedure. The following err.conf has been tested
+on latest Montecito PAL.
+
+err.conf:
+
+#This is configuration file for err_inject_tool.
+#The format of the each line is:
+#cpu, loop, interval, err_type_info, err_struct_info, err_data_buffer
+#where
+# cpu: logical cpu number the error will be inject in.
+# loop: times the error will be injected.
+# interval: In second. every so often one error is injected.
+# err_type_info, err_struct_info: PAL parameters.
+#
+#Note: All values are hex w/o or w/ 0x prefix.
+
+
+#On cpu2, inject only total 0x10 errors, interval 5 seconds
+#corrected, data cache, hier-2, physical addr(assigned by tool code).

BCM43xx Linux Driver Project
============================
-About this software
--------------------
+Introduction
+------------
-The goal of this project is to develop a linux driver for Broadcom
-BCM43xx chips, based on the specification at
-http://bcm-specs.sipsolutions.net/
+Many of the wireless devices found in modern notebook computers are
+based on the wireless chips produced by Broadcom. These devices have
+been a problem for Linux users as there is no open-source driver
+available. In addition, Broadcom has not released specifications
+for the device, and driver availability has been limited to the
+binary-only form used in the GPL versions of AP hardware such as the
+Linksys WRT54G, and the Windows and OS X drivers. Before this project
+began, the only way to use these devices were to use the Windows or
+OS X drivers with either the Linuxant or ndiswrapper modules. There
+is a strong penalty if this method is used as loading the binary-only
+module "taints" the kernel, and no kernel developer will help diagnose
+any kernel problems.
-The project page is http://bcm43xx.berlios.de/
+Development
+-----------
+This driver has been developed using
+a clean-room technique that is described at
+http://bcm-specs.sipsolutions.net/ReverseEngineeringProcess. For legal
+reasons, none of the clean-room crew works on the on the Linux driver,
+and none of the Linux developers sees anything but the specifications,
+which are the ultimate product of the reverse-engineering group.
-Requirements
-------------
+Software
+--------
+
+Since the release of the 2.6.17 kernel, the bcm43xx driver has been
+distributed with the kernel source, and is prebuilt in most, if not
+all, distributions. There is, however, additional software that is
+required. The firmware used by the chip is the intellectual property
+of Broadcom and they have not given the bcm43xx team redistribution
+rights to this firmware. Since we cannot legally redistribute
+the firwmare we cannot include it with the driver. Furthermore, it
+cannot be placed in the downloadable archives of any distributing
+organization; therefore, the user is responsible for obtaining the
+firmware and placing it in the appropriate location so that the driver
+can find it when initializing.
+
+To help with this process, the bcm43xx developers provide a separate
+program named bcm43xx-fwcutter to "cut" the firmware out of a
+Windows or OS X driver and write the extracted files to the proper
+location. This program is usually provided with the distribution;
+however, it may be downloaded from
+
+http://developer.berlios.de/project/showfiles.php?group_id=4547
-1) Linux Kernel 2.6.16 or later
- http://www.kernel.org/
+The firmware is available in two versions. V3 firmware is used with
+the in-kernel bcm43xx driver that uses a software MAC layer called
+SoftMAC, and will have a microcode revision of 0x127 or smaller. The
+V4 firmware is used by an out-of-kernel driver employing a variation of
+the Devicescape MAC layer known as d80211. Once bcm43xx-d80211 reaches
+a satisfactory level of development, it will replace bcm43xx-softmac
+in the kernel as it is much more flexible and powerful.
- You may want to configure your kernel with:
+A source for the latest V3 firmware is
- CONFIG_DEBUG_FS (optional):
- -> Kernel hacking
- -> Debug Filesystem
+http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
-2) SoftMAC IEEE 802.11 Networking Stack extension and patched ieee80211
- modules:
- http://softmac.sipsolutions.net/
+Once this file is downloaded, the command
+'bcm43xx-fwcutter -w <dir> <filename>'
+will extract the microcode and write it to directory
+<dir>. The correct directory will depend on your distribution;
+however, most use '/lib/firmware'. Once this step is completed,
+the bcm3xx driver should load when the system is booted. To see
+any messages relating to the driver, issue the command 'dmesg |
+grep bcm43xx' from a terminal window. If there are any problems,
+please send that output to Bcm43xx-dev@lists.berlios.de.
-3) Firmware Files
+Although the driver has been in-kernel since 2.6.17, the earliest
+version is quite limited in its capability. Patches that include
+all features of later versions are available for the stable kernel
+versions from 2.6.18. These will be needed if you use a BCM4318,
+or a PCI Express version (BCM4311 and BCM4312). In addition, if you
+have an early BCM4306 and more than 1 GB RAM, your kernel will need
+to be patched. These patches, which are being updated regularly,
+are available at ftp://lwfinger.dynalias.org/patches. Look for
+combined_2.6.YY.patch. Of course you will need kernel source downloaded
+from kernel.org, or the source from your distribution.
- Please try fwcutter. Fwcutter can extract the firmware from various
- binary driver files. It supports driver files from Windows, MacOS and
- Linux. You can get fwcutter from http://bcm43xx.berlios.de/.
- Also, fwcutter comes with a README file for further instructions.
+If you build your own kernel, please enable CONFIG_BCM43XX_DEBUG
+and CONFIG_IEEE80211_SOFTMAC_DEBUG. The log information provided is
+essential for solving any problems.

+ RxRPC NETWORK PROTOCOL
+ ======================
+
+The RxRPC protocol driver provides a reliable two-phase transport on top of UDP
+that can be used to perform RxRPC remote operations. This is done over sockets
+of AF_RXRPC family, using sendmsg() and recvmsg() with control data to send and
+receive data, aborts and errors.

+
+========
+OVERVIEW
+========
+
+RxRPC is a two-layer protocol. There is a session layer which provides
+reliable virtual connections using UDP over IPv4 (or IPv6) as the transport
+layer, but implements a real network protocol; and there's the presentation
+layer which renders structured data to binary blobs and back again using XDR
+(as does SunRPC):
+
+ +-------------+
+ | Application |
+ +-------------+
+ | XDR | Presentation
+ +-------------+
+ | RxRPC | Session
+ +-------------+
+ | UDP | Transport
+ +-------------+
+
+
+AF_RXRPC provides:
+
+ (1) Part of an RxRPC facility for both kernel and userspace applications by
+ making the session part of it a Linux network protocol (AF_RXRPC).
+
+ (2) A two-phase protocol. The client transmits a blob (the request) and then
+ receives a blob (the reply), and the server receives the request and then
+ transmits the reply.
+
+ (3) Retention of the reusable bits of the transport system set up for one call
+ to speed up subsequent calls.
+
+ (4) A secure protocol, using the Linux kernel's key retention facility to
+ manage security on the client end. The server end must of necessity be
+ more active in security negotiations.
+
+AF_RXRPC does not provide XDR marshalling/presentation facilities. That is
+left to the application. AF_RXRPC only deals in blobs. Even the operation ID
+is just the first four bytes of the request blob, and as such is beyond the
+kernel's interest.
+
+
+Sockets of AF_RXRPC family are:
+
+ (1) created as type SOCK_DGRAM;
+
+ (2) provided with a protocol of the type of underlying transport they're going
+ to use - currently only PF_INET is supported.
+
+
+The Andrew File System (AFS) is an example of an application that uses this and
+that has both kernel (filesystem) and userspace (utility) components.
+
+
+======================
+RXRPC PROTOCOL SUMMARY
+======================
+
+An overview of the RxRPC protocol:
+
+ (*) RxRPC sits on top of another networking protocol (UDP is the only option
+ currently), and uses this to provide network transport. UDP ports, for
+ example, provide transport endpoints.
+
+ (*) RxRPC supports multiple virtual "connections" from any given transport
+ endpoint, thus allowing the endpoints to be shared, even to the same
+ remote endpoint.
+
+ (*) Each connection goes to a particular "service". A connection may not go
+ to multiple services. A service may be considered the RxRPC equivalent of
+ a port number. AF_RXRPC permits multiple services to share an endpoint.
+
+ (*) Client-originating packets are marked, thus a transport endpoint can be
+ shared between client and server connections (connections have a
+ direction).
+
+ (*) Up to a billion connections may be supported concurrently between one
+ local transport endpoint and one service on one remote endpoint. An RxRPC
+ connection is described by seven numbers:
+
+ Local address }
+ Local port } Transport (UDP) address
+ Remote address }
+ Remote port }
+ Direction
+ Connection ID
+ Service ID
+
+ (*) Each RxRPC operation is a "call". A connection may make up to four
+ billion calls, but only up to four calls may be in progress on a
+ connection at any one time.
+
+ (*) Calls are two-phase and asymmetric: the client sends its request data,
+ which the service receives; then the service transmits the reply data
+ which the client receives.
+
+ (*) The data blobs are of indefinite size, the end of a phase is marked with a
+ flag in the packet. The number of packets of data making up one blob may
+ not exceed 4 billion, however, as this would cause the sequence number to
+ wrap.
+
+ (*) The first four bytes of the request data are the service operation ID.
+
+ (*) Security is negotiated on a per-connection basis. The connection is
+ initiated by the first data packet on it arriving. If security is
+ requested, the server then issues a "challenge" and then the client
+ replies with a "response". If the response is successful, the security is
+ set for the lifetime of that connection, and all subsequent calls made
+ upon it use that same security. In the event that the server lets a
+ connection lapse before the client, the security will be renegotiated if
+ the client uses the connection again.
+
+ (*) Calls use ACK packets to handle reliability. Data packets are also
+ explicitly sequenced per call.
+
+ (*) There are two types of positive acknowledgement: hard-ACKs and soft-ACKs.
+ A hard-ACK indicates to the far side that all the data received to a point
+ has been received and processed; a soft-ACK indicates that the data has
+ been received but may yet be discarded and re-requested. The sender may
+ not discard any transmittable packets until they've been hard-ACK'd.
+
+ (*) Reception of a reply data packet implicitly hard-ACK's all the data
+ packets that make up the request.
+
+ (*) An call is complete when the request has been sent, the reply has been
+ received and the final hard-ACK on the last packet of the reply has
+ reached the server.
+
+ (*) An call may be aborted by either end at any time up to its completion.
+
+
+=====================
+AF_RXRPC DRIVER MODEL
+=====================
+
+About the AF_RXRPC driver:
+
+ (*) The AF_RXRPC protocol transparently uses internal sockets of the transport
+ protocol to represent transport endpoints.
+
+ (*) AF_RXRPC sockets map onto RxRPC connection bundles. Actual RxRPC
+ connections are handled transparently. One client socket may be used to
+ make multiple simultaneous calls to the same service. One server socket
+ may handle calls from many clients.
+
+ (*) Additional parallel client connections will be initiated to support extra
+ concurrent calls, up to a tunable limit.
+
+ (*) Each connection is retained for a certain amount of time [tunable] after
+ the last call currently using it has completed in case a new call is made
+ that could reuse it.
+
+ (*) Each internal UDP socket is retained [tunable] for a certain amount of
+ time [tunable] after the last connection using it discarded, in case a new
+ connection is made that could use it.
+
+ (*) A client-side connection is only shared between calls if they have have
+ the same key struct describing their security (and assuming the calls
+ would otherwise share the connection). Non-secured calls would also be
+ able to share connections with each other.
+
+ (*) A server-side connection is shared if the client says it is.
+
+ (*) ACK'ing is handled by the protocol driver automatically, including ping
+ replying.
+
+ (*) SO_KEEPALIVE automatically pings the other side to keep the connection
+ alive [TODO].
+
+ (*) If an ICMP error is received, all calls affected by that error will be
+ aborted with an appropriate network error passed through recvmsg().
+
+
+Interaction with the user of the RxRPC socket:
+
+ (*) A socket is made into a server socket by binding an address with a
+ non-zero service ID.
+
+ (*) In the client, sending a request is achieved with one or more sendmsgs,
+ followed by the reply being received with one or more recvmsgs.
+
+ (*) The first sendmsg for a request to be sent from a client contains a tag to
+ be used in all other sendmsgs or recvmsgs associated with that call. The
+ tag is carried in the control data.
+
+ (*) connect() is used to supply a default destination address for a client
+ socket. This may be overridden by supplying an alternate address to the
+ first sendmsg() of a call (struct msghdr::msg_name).
+
+ (*) If connect() is called on an unbound client, a random local port will
+ bound before the operation takes place.
+
+ (*) A server socket may also be used to make client calls. To do this, the
+ first sendmsg() of the call must specify the target address. The server's
+ transport endpoint is used to send the packets.
+
+ (*) Once the application has received the last message associated with a call,
+ the tag is guaranteed not to be seen again, and so it can be used to pin
+ client resources. A new call can then be initiated with the same tag
+ without fear of interference.
+
+ (*) In the server, a request is received with one or more recvmsgs, then the
+ the reply is transmitted with one or more sendmsgs, and then the final ACK
+ is received with a last recvmsg.
+
+ (*) When sending data for a call, sendmsg is given MSG_MORE if there's more
+ data to come on that call.
+
+ (*) When receiving data for a call, recvmsg flags MSG_MORE if there's more
+ data to come for that call.
+
+ (*) When receiving data or messages for a call, MSG_EOR is flagged by recvmsg
+ to indicate the terminal message for that call.
+
+ (*) A call may be aborted by adding an abort control message to the control
+ data. Issuing an abort terminates the kernel's use of that call's tag.
+ Any messages waiting in the receive queue for that call will be discarded.
+
+ (*) Aborts, busy notifications and challenge packets are delivered by recvmsg,
+ and control data messages will be set to indicate the context. Receiving
+ an abort or a busy message terminates the kernel's use of that call's tag.
+
+ (*) The control data part of the msghdr struct is used for a number of things:
+
+ (*) The tag of the intended or affected call.
+
+ (*) Sending or receiving errors, aborts and busy notifications.
+
+ (*) Notifications of incoming calls.
+
+ (*) Sending debug requests and receiving debug replies [TODO].
+
+ (*) When the kernel has received and set up an incoming call, it sends a
+ message to server application to let it know there's a new call awaiting
+ its acceptance [recvmsg reports a special control message]. The server
+ application then uses sendmsg to assign a tag to the new call. Once that
+ is done, the first part of the request data will be delivered by recvmsg.
+
+ (*) The server application has to provide the server socket with a keyring of
+ secret keys corresponding to the security types it permits. When a secure
+ connection is being set up, the kernel looks up the appropriate secret key
+ in the keyring and then sends a challenge packet to the client and
+ receives a response packet. The kernel then checks the authorisation of
+ the packet and either aborts the connection or sets up the security.
+
+ (*) The name of the key a client will use to secure its communications is
+ nominated by a socket option.
+
+
+Notes on recvmsg:
+
+ (*) If there's a sequence of data messages belonging to a particular call on
+ the receive queue, then recvmsg will keep working through them until:
+
+ (a) it meets the end of that call's received data,
+
+ (b) it meets a non-data message,
+
+ (c) it meets a message belonging to a different call, or
+
+ (d) it fills the user buffer.
+
+ If recvmsg is called in blocking mode, it will keep sleeping, awaiting the
+ reception of further data, until one of the above four conditions is met.
+
+ (2) MSG_PEEK operates similarly, but will return immediately if it has put any
+ data in the buffer rather than sleeping until it can fill the buffer.
+
+ (3) If a data message is only partially consumed in filling a user buffer,
+ then the remainder of that message will be left on the front of the queue
+ for the next taker. MSG_TRUNC will never be flagged.
+
+ (4) If there is more data to be had on a call (it hasn't copied the last byte
+ of the last data message in that phase yet), then MSG_MORE will be
+ flagged.
+
+
+================
+CONTROL MESSAGES
+================
+
+AF_RXRPC makes use of control messages in sendmsg() and recvmsg() to multiplex
+calls, to invoke certain actions and to report certain conditions. These are:
+
+ MESSAGE ID SRT DATA MEANING
+ ======================= === =========== ===============================
+ RXRPC_USER_CALL_ID sr- User ID App's call specifier
+ RXRPC_ABORT srt Abort code Abort code to issue/received
+ RXRPC_ACK -rt n/a Final ACK received
+ RXRPC_NET_ERROR -rt error num Network error on call
+ RXRPC_BUSY -rt n/a Call rejected (server busy)
+ RXRPC_LOCAL_ERROR -rt error num Local error encountered
+ RXRPC_NEW_CALL -r- n/a New call received
+ RXRPC_ACCEPT s-- n/a Accept new call
+
+ (SRT = usable in Sendmsg / delivered by Recvmsg / Terminal message)
+
+ (*) RXRPC_USER_CALL_ID
+
+ This is used to indicate the application's call ID. It's an unsigned long
+ that the app specifies in the client by attaching it to the first data
+ message or in the server by passing it in association with an RXRPC_ACCEPT
+ message. recvmsg() passes it in conjunction with all messages except
+ those of the RXRPC_NEW_CALL message.
+
+ (*) RXRPC_ABORT
+
+ This is can be used by an application to abort a call by passing it to
+ sendmsg, or it can be delivered by recvmsg to indicate a remote abort was
+ received. Either way, it must be associated with an RXRPC_USER_CALL_ID to
+ specify the call affected. If an abort is being sent, then error EBADSLT
+ will be returned if there is no call with that user ID.
+
+ (*) RXRPC_ACK
+
+ This is delivered to a server application to indicate that the final ACK
+ of a call was received from the client. It will be associated with an
+ RXRPC_USER_CALL_ID to indicate the call that's now complete.
+
+ (*) RXRPC_NET_ERROR
+
+ This is delivered to an application to indicate that an ICMP error message
+ was encountered in the process of trying to talk to the peer. An
+ errno-class integer value will be included in the control message data
+ indicating the problem, and an RXRPC_USER_CALL_ID will indicate the call
+ affected.
+
+ (*) RXRPC_BUSY
+
+ This is delivered to a client application to indicate that a call was
+ rejected by the server due to the server being busy. It will be
+ associated with an RXRPC_USER_CALL_ID to indicate the rejected call.
+
+ (*) RXRPC_LOCAL_ERROR
+
+ This is delivered to an application to indicate that a local error was
+ encountered and that a call has been aborted because of it. An
+ errno-class integer value will be included in the control message data
+ indicating the problem, and an RXRPC_USER_CALL_ID will indicate the call
+ affected.
+
+ (*) RXRPC_NEW_CALL
+
+ This is delivered to indicate to a server application that a new call has
+ arrived and is awaiting acceptance. No user ID is associated with this,
+ as a user ID must subsequently be assigned by doing an RXRPC_ACCEPT.
+
+ (*) RXRPC_ACCEPT
+
+ This is used by a server application to attempt to accept a call and
+ assign it a user ID. It should be associated with an RXRPC_USER_CALL_ID
+ to indicate the user ID to be assigned. If there is no call to be
+ accepted (it may have timed out, been aborted, etc.), then sendmsg will
+ return error ENODATA. If the user ID is already in use by another call,
+ then error EBADSLT will be returned.
+
+
+==============
+SOCKET OPTIONS
+==============
+
+AF_RXRPC sockets support a few socket options at the SOL_RXRPC level:
+
+ (*) RXRPC_SECURITY_KEY
+
+ This is used to specify the description of the key to be used. The key is
+ extracted from the calling process's keyrings with request_key() and
+ should be of "rxrpc" type.
+
+ The optval pointer points to the description string, and optlen indicates
+ how long the string is, without the NUL terminator.
+
+ (*) RXRPC_SECURITY_KEYRING
+
+ Similar to above but specifies a keyring of server secret keys to use (key
+ type "keyring"). See the "Security" section.
+
+ (*) RXRPC_EXCLUSIVE_CONNECTION
+
+ This is used to request that new connections should be used for each call
+ made subsequently on this socket. optval should be NULL and optlen 0.
+
+ (*) RXRPC_MIN_SECURITY_LEVEL
+
+ This is used to specify the minimum security level required for calls on
+ this socket. optval must point to an int containing one of the following
+ values:
+
+ (a) RXRPC_SECURITY_PLAIN
+
+ Encrypted checksum only.
+
+ (b) RXRPC_SECURITY_AUTH
+
+ Encrypted checksum plus packet padded and first eight bytes of packet
+ encrypted - which includes the actual packet length.
+
+ (c) RXRPC_SECURITY_ENCRYPTED
+
+ Encrypted checksum plus entire packet padded and encrypted, including
+ actual packet length.
+
+
+========
+SECURITY
+========
+
+Currently, only the kerberos 4 equivalent protocol has been implemented
+(security index 2 - rxkad). This requires the rxkad module to be loaded and,
+on the client, tickets of the appropriate type to be obtained from the AFS
+kaserver or the kerberos server and installed as "rxrpc" type keys. This is
+normally done using the klog program. An example simple klog program can be
+found at:
+
+ http://people.redhat.com/~dhowells/rxrpc/klog.c
+
+The payload provided to add_key() on the client should be of the following
+form:
+
+ struct rxrpc_key_sec2_v1 {
+ uint16_t security_index; /* 2 */
+ uint16_t ticket_length; /* length of ticket[] */
+ uint32_t expiry; /* time at which expires */
+ uint8_t kvno; /* key version number */
+ uint8_t __pad[3];
+ uint8_t session_key[8]; /* DES session key */
+ uint8_t ticket[0]; /* the encrypted ticket */
+ };
+
+Where the ticket blob is just appended to the above structure.
+
+
+For the server, keys of type "rxrpc_s" must be made available to the server.
+They have a description of "<serviceID>:<securityIndex>" (eg: "52:2" for an
+rxkad key for the AFS VL service). When such a key is created, it should be
+given the server's secret key as the instantiation data (see the example
+below).
+
+ add_key("rxrpc_s", "52:2", secret_key, 8, keyring);
+
+A keyring is passed to the server socket by naming it in a sockopt. The server
+socket then looks the server secret keys up in this keyring when secure
+incoming connections are made. This can be seen in an example program that can
+be found at:
+
+ http://people.redhat.com/~dhowells/rxrpc/listen.c
+
+
+====================
+EXAMPLE CLIENT USAGE
+====================
+
+A client would issue an operation by:
+
+ (1) An RxRPC socket is set up by:
+
+ client = socket(AF_RXRPC, SOCK_DGRAM, PF_INET);
+
+ Where the third parameter indicates the protocol family of the transport
+ socket used - usually IPv4 but it can also be IPv6 [TODO].
+
+ (2) A local address can optionally be bound:
+
+ struct sockaddr_rxrpc srx = {
+ .srx_family = AF_RXRPC,
+ .srx_service = 0, /* we're a client */
+ .transport_type = SOCK_DGRAM, /* type of transport socket */
+ .transport.sin_family = AF_INET,
+ .transport.sin_port = htons(7000), /* AFS callback */
+ .transport.sin_address = 0, /* all local interfaces */
+ };
+ bind(client, &srx, sizeof(srx));
+
+ This specifies the local UDP port to be used. If not given, a random
+ non-privileged port will be used. A UDP port may be shared between
+ several unrelated RxRPC sockets. Security is handled on a basis of
+ per-RxRPC virtual connection.
+
+ (3) The security is set:
+
+ const char *key = "AFS:cambridge.redhat.com";
+ setsockopt(client, SOL_RXRPC, RXRPC_SECURITY_KEY, key, strlen(key));
+
+ This issues a request_key() to get the key representing the security
+ context. The minimum security level can be set:
+
+ unsigned int sec = RXRPC_SECURITY_ENCRYPTED;
+ setsockopt(client, SOL_RXRPC, RXRPC_MIN_SECURITY_LEVEL,
+ &sec, sizeof(sec));
+
+ (4) The server to be contacted can then be specified (alternatively this can
+ be done through sendmsg):
+
+ struct sockaddr_rxrpc srx = {
+ .srx_family = AF_RXRPC,
+ .srx_service = VL_SERVICE_ID,
+ .transport_type = SOCK_DGRAM, /* type of transport socket */
+ .transport.sin_family = AF_INET,
+ .transport.sin_port = htons(7005), /* AFS volume manager */
+ .transport.sin_address = ...,
+ };
+ connect(client, &srx, sizeof(srx));
+
+ (5) The request data should then be posted to the server socket using a series
+ of sendmsg() calls, each with the following control message attached:
+
+ RXRPC_USER_CALL_ID - specifies the user ID for this call
+
+ MSG_MORE should be set in msghdr::msg_flags on all but the last part of
+ the request. Multiple requests may be made simultaneously.
+
+ If a call is intended to go to a destination other then the default
+ specified through connect(), then msghdr::msg_name should be set on the
+ first request message of that call.
+
+ (6) The reply data will then be posted to the server socket for recvmsg() to
+ pick up. MSG_MORE will be flagged by recvmsg() if there's more reply data
+ for a particular call to be read. MSG_EOR will be set on the terminal
+ read for a call.
+
+ All data will be delivered with the following control message attached:
+
+ RXRPC_USER_CALL_ID - specifies the user ID for this call
+
+ If an abort or error occurred, this will be returned in the control data
+ buffer instead, and MSG_EOR will be flagged to indicate the end of that
+ call.
+
+
+====================
+EXAMPLE SERVER USAGE
+====================
+
+A server would be set up to accept operations in the following manner:
+
+ (1) An RxRPC socket is created by:
+
+ server = socket(AF_RXRPC, SOCK_DGRAM, PF_INET);
+
+ Where the third parameter indicates the address type of the transport
+ socket used - usually IPv4.
+
+ (2) Security is set up if desired by giving the socket a keyring with server
+ secret keys in it:
+
+ keyring = add_key("keyring", "AFSkeys", NULL, 0,
+ KEY_SPEC_PROCESS_KEYRING);
+
+ const char secret_key[8] = {
+ 0xa7, 0x83, 0x8a, 0xcb, 0xc7, 0x83, 0xec, 0x94 };
+ add_key("rxrpc_s", "52:2", secret_key, 8, keyring);
+
+ setsockopt(server, SOL_RXRPC, RXRPC_SECURITY_KEYRING, "AFSkeys", 7);
+
+ The keyring can be manipulated after it has been given to the socket. This
+ permits the server to add more keys, replace keys, etc. whilst it is live.
+
+ (2) A local address must then be bound:
+
+ struct sockaddr_rxrpc srx = {
+ .srx_family = AF_RXRPC,
+ .srx_service = VL_SERVICE_ID, /* RxRPC service ID */
+ .transport_type = SOCK_DGRAM, /* type of transport socket */
+ .transport.sin_family = AF_INET,
+ .transport.sin_port = htons(7000), /* AFS callback */
+ .transport.sin_address = 0, /* all local interfaces */
+ };
+ bind(server, &srx, sizeof(srx));
+
+ (3) The server is then set to listen out for incoming calls:
+
+ listen(server, 100);
+
+ (4) The kernel notifies the server of pending incoming connections by sending
+ it a message for each. This is received with recvmsg() on the server
+ socket. It has no data, and has a single dataless control message
+ attached:
+
+ RXRPC_NEW_CALL
+
+ The address that can be passed back by recvmsg() at this point should be
+ ignored since the call for which the message was posted may have gone by
+ the time it is accepted - in which case the first call still on the queue
+ will be accepted.
+
+ (5) The server then accepts the new call by issuing a sendmsg() with two
+ pieces of control data and no actual data:
+
+ RXRPC_ACCEPT - indicate connection acceptance
+ RXRPC_USER_CALL_ID - specify user ID for this call
+
+ (6) The first request data packet will then be posted to the server socket for
+ recvmsg() to pick up. At that point, the RxRPC address for the call can
+ be read from the address fields in the msghdr struct.
+
+ Subsequent request data will be posted to the server socket for recvmsg()
+ to collect as it arrives. All but the last piece of the request data will
+ be delivered with MSG_MORE flagged.
+
+ All data will be delivered with the following control message attached:
+
+ RXRPC_USER_CALL_ID - specifies the user ID for this call
+
+ (8) The reply data should then be posted to the server socket using a series
+ of sendmsg() calls, each with the following control messages attached:
+
+ RXRPC_USER_CALL_ID - specifies the user ID for this call
+
+ MSG_MORE should be set in msghdr::msg_flags on all but the last message
+ for a particular call.
+
+ (9) The final ACK from the client will be posted for retrieval by recvmsg()
+ when it is received. It will take the form of a dataless message with two
+ control messages attached:
+
+ RXRPC_USER_CALL_ID - specifies the user ID for this call
+ RXRPC_ACK - indicates final ACK (no data)
+
+ MSG_EOR will be flagged to indicate that this is the final message for
+ this call.
+
+(10) Up to the point the final packet of reply data is sent, the call can be
+ aborted by calling sendmsg() with a dataless message with the following
+ control messages attached:
+
+ RXRPC_USER_CALL_ID - specifies the user ID for this call
+ RXRPC_ABORT - indicates abort code (4 byte data)
+
+ Any packets waiting in the socket's receive queue will be discarded if
+ this is issued.
+
+Note that all the communications for a particular service take place through
+the one server socket, using control messages on sendmsg() and recvmsg() to
+determine the call affected.
+
+
+=========================
+AF_RXRPC KERNEL INTERFACE
+=========================
+
+The AF_RXRPC module also provides an interface for use by in-kernel utilities
+such as the AFS filesystem. This permits such a utility to:
+
+ (1) Use different keys directly on individual client calls on one socket
+ rather than having to open a whole slew of sockets, one for each key it
+ might want to use.
+
+ (2) Avoid having RxRPC call request_key() at the point of issue of a call or
+ opening of a socket. Instead the utility is responsible for requesting a
+ key at the appropriate point. AFS, for instance, would do this during VFS
+ operations such as open() or unlink(). The key is then handed through
+ when the call is initiated.
+
+ (3) Request the use of something other than GFP_KERNEL to allocate memory.
+
+ (4) Avoid the overhead of using the recvmsg() call. RxRPC messages can be
+ intercepted before they get put into the socket Rx queue and the socket
+ buffers manipulated directly.
+
+To use the RxRPC facility, a kernel utility must still open an AF_RXRPC socket,
+bind an addess as appropriate and listen if it's to be a server socket, but
+then it passes this to the kernel interface functions.
+
+The kernel interface functions are as follows:
+
+ (*) Begin a new client call.
+
+ struct rxrpc_call *
+ rxrpc_kernel_begin_call(struct socket *sock,
+ struct sockaddr_rxrpc *srx,
+ struct key *key,
+ unsigned long user_call_ID,
+ gfp_t gfp);
+
+ This allocates the infrastructure to make a new RxRPC call and assigns
+ call and connection numbers. The call will be made on the UDP port that
+ the socket is bound to. The call will go to the destination address of a
+ connected client socket unless an alternative is supplied (srx is
+ non-NULL).
+
+ If a key is supplied then this will be used to secure the call instead of
+ the key bound to the socket with the RXRPC_SECURITY_KEY sockopt. Calls
+ secured in this way will still share connections if at all possible.
+
+ The user_call_ID is equivalent to that supplied to sendmsg() in the
+ control data buffer. It is entirely feasible to use this to point to a
+ kernel data structure.
+
+ If this function is successful, an opaque reference to the RxRPC call is
+ returned. The caller now holds a reference on this and it must be
+ properly ended.
+
+ (*) End a client call.
+
+ void rxrpc_kernel_end_call(struct rxrpc_call *call);
+
+ This is used to end a previously begun call. The user_call_ID is expunged
+ from AF_RXRPC's knowledge and will not be seen again in association with
+ the specified call.
+
+ (*) Send data through a call.
+
+ int rxrpc_kernel_send_data(struct rxrpc_call *call, struct msghdr *msg,
+ size_t len);
+
+ This is used to supply either the request part of a client call or the
+ reply part of a server call. msg.msg_iovlen and msg.msg_iov specify the
+ data buffers to be used. msg_iov may not be NULL and must point
+ exclusively to in-kernel virtual addresses. msg.msg_flags may be given
+ MSG_MORE if there will be subsequent data sends for this call.
+
+ The msg must not specify a destination address, control data or any flags
+ other than MSG_MORE. len is the total amount of data to transmit.
+
+ (*) Abort a call.
+
+ void rxrpc_kernel_abort_call(struct rxrpc_call *call, u32 abort_code);
+
+ This is used to abort a call if it's still in an abortable state. The
+ abort code specified will be placed in the ABORT message sent.
+
+ (*) Intercept received RxRPC messages.
+
+ typedef void (*rxrpc_interceptor_t)(struct sock *sk,
+ unsigned long user_call_ID,
+ struct sk_buff *skb);
+
+ void
+ rxrpc_kernel_intercept_rx_messages(struct socket *sock,
+ rxrpc_interceptor_t interceptor);
+
+ This installs an interceptor function on the specified AF_RXRPC socket.
+ All messages that would otherwise wind up in the socket's Rx queue are
+ then diverted to this function. Note that care must be taken to process
+ the messages in the right order to maintain DATA message sequentiality.
+
+ The interceptor function itself is provided with the address of the socket
+ and handling the incoming message, the ID assigned by the kernel utility
+ to the call and the socket buffer containing the message.
+
+ The skb->mark field indicates the type of message:
+
+ MARK MEANING
+ =============================== =======================================
+ RXRPC_SKB_MARK_DATA Data message
+ RXRPC_SKB_MARK_FINAL_ACK Final ACK received for an incoming call
+ RXRPC_SKB_MARK_BUSY Client call rejected as server busy
+ RXRPC_SKB_MARK_REMOTE_ABORT Call aborted by peer
+ RXRPC_SKB_MARK_NET_ERROR Network error detected
+ RXRPC_SKB_MARK_LOCAL_ERROR Local error encountered
+ RXRPC_SKB_MARK_NEW_CALL New incoming call awaiting acceptance
+
+ The remote abort message can be probed with rxrpc_kernel_get_abort_code().
+ The two error messages can be probed with rxrpc_kernel_get_error_number().
+ A new call can be accepted with rxrpc_kernel_accept_call().
+
+ Data messages can have their contents extracted with the usual bunch of
+ socket buffer manipulation functions. A data message can be determined to
+ be the last one in a sequence with rxrpc_kernel_is_data_last(). When a
+ data message has been used up, rxrpc_kernel_data_delivered() should be
+ called on it..
+
+ Non-data messages should be handled to rxrpc_kernel_free_skb() to dispose
+ of. It is possible to get extra refs on all types of message for later
+ freeing, but this may pin the state of a call until the message is finally
+ freed.
+
+ (*) Accept an incoming call.
+
+ struct rxrpc_call *
+ rxrpc_kernel_accept_call(struct socket *sock,
+ unsigned long user_call_ID);
+
+ This is used to accept an incoming call and to assign it a call ID. This
+ function is similar to rxrpc_kernel_begin_call() and calls accepted must
+ be ended in the same way.
+
+ If this function is successful, an opaque reference to the RxRPC call is
+ returned. The caller now holds a reference on this and it must be
+ properly ended.
+
+ (*) Reject an incoming call.
+
+ int rxrpc_kernel_reject_call(struct socket *sock);
+
+ This is used to reject the first incoming call on the socket's queue with
+ a BUSY message. -ENODATA is returned if there were no incoming calls.
+ Other errors may be returned if the call had been aborted (-ECONNABORTED)
+ or had timed out (-ETIME).
+
+ (*) Record the delivery of a data message and free it.
+
+ void rxrpc_kernel_data_delivered(struct sk_buff *skb);
+
+ This is used to record a data message as having been delivered and to
+ update the ACK state for the call. The socket buffer will be freed.
+
+ (*) Free a message.
+
+ void rxrpc_kernel_free_skb(struct sk_buff *skb);
+
+ This is used to free a non-DATA socket buffer intercepted from an AF_RXRPC
+ socket.
+
+ (*) Determine if a data message is the last one on a call.
+
+ bool rxrpc_kernel_is_data_last(struct sk_buff *skb);
+
+ This is used to determine if a socket buffer holds the last data message
+ to be received for a call (true will be returned if it does, false
+ if not).
+
+ The data message will be part of the reply on a client call and the
+ request on an incoming call. In the latter case there will be more
+ messages, but in the former case there will not.
+
+ (*) Get the abort code from an abort message.
+
+ u32 rxrpc_kernel_get_abort_code(struct sk_buff *skb);
+
+ This is used to extract the abort code from a remote abort message.
+
+ (*) Get the error number from a local or network error message.
+
+ int rxrpc_kernel_get_error_number(struct sk_buff *skb);
+
+ This is used to extract the error number from a message indicating either
+ a local error occurred or a network error occurred.

+Debugging suspend and resume
+ (C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Testing suspend to disk (STD)
+
+To verify that the STD works, you can try to suspend in the "reboot" mode:
+
+# echo reboot > /sys/power/disk
+# echo disk > /sys/power/state
+
+and the system should suspend, reboot, resume and get back to the command prompt
+where you have started the transition. If that happens, the STD is most likely
+to work correctly, but you need to repeat the test at least a couple of times in
+a row for confidence. This is necessary, because some problems only show up on
+a second attempt at suspending and resuming the system. You should also test
+the "platform" and "shutdown" modes of suspend:
+
+# echo platform > /sys/power/disk
+# echo disk > /sys/power/state
+
+or
+
+# echo shutdown > /sys/power/disk
+# echo disk > /sys/power/state
+
+in which cases you will have to press the power button to make the system
+resume. If that does not work, you will need to identify what goes wrong.
+
+a) Test mode of STD
+
+To verify if there are any drivers that cause problems you can run the STD
+in the test mode:
+
+# echo test > /sys/power/disk
+# echo disk > /sys/power/state
+
+in which case the system should freeze tasks, suspend devices, disable nonboot
+CPUs (if any), wait for 5 seconds, enable nonboot CPUs, resume devices, thaw
+tasks and return to your command prompt. If that fails, most likely there is
+a driver that fails to either suspend or resume (in the latter case the system
+may hang or be unstable after the test, so please take that into consideration).
+To find this driver, you can carry out a binary search according to the rules:
+- if the test fails, unload a half of the drivers currently loaded and repeat
+(that would probably involve rebooting the system, so always note what drivers
+have been loaded before the test),
+- if the test succeeds, load a half of the drivers you have unloaded most
+recently and repeat.
+
+Once you have found the failing driver (there can be more than just one of
+them), you have to unload it every time before the STD transition. In that case
+please make sure to report the problem with the driver.
+
+It is also possible that a cycle can still fail after you have unloaded
+all modules. In that case, you would want to look in your kernel configuration
+for the drivers that can be compiled as modules (testing again with them as
+modules), and possibly also try boot time options such as "noapic" or "noacpi".
+
+b) Testing minimal configuration
+
+If the test mode of STD works, you can boot the system with "init=/bin/bash"
+and attempt to suspend in the "reboot", "shutdown" and "platform" modes. If
+that does not work, there probably is a problem with a driver statically
+compiled into the kernel and you can try to compile more drivers as modules,
+so that they can be tested individually. Otherwise, there is a problem with a
+modular driver and you can find it by loading a half of the modules you normally
+use and binary searching in accordance with the algorithm:
+- if there are n modules loaded and the attempt to suspend and resume fails,
+unload n/2 of the modules and try again (that would probably involve rebooting
+the system),
+- if there are n modules loaded and the attempt to suspend and resume succeeds,
+load n/2 modules more and try again.
+
+Again, if you find the offending module(s), it(they) must be unloaded every time
+before the STD transition, and please report the problem with it(them).
+
+c) Advanced debugging
+
+In case the STD does not work on your system even in the minimal configuration
+and compiling more drivers as modules is not practical or some modules cannot
+be unloaded, you can use one of the more advanced debugging techniques to find
+the problem. First, if there is a serial port in your box, you can set the
+CONFIG_DISABLE_CONSOLE_SUSPEND kernel configuration option and try to log kernel
+messages using the serial console. This may provide you with some information
+about the reasons of the suspend (resume) failure. Alternatively, it may be
+possible to use a FireWire port for debugging with firescope
+(ftp://ftp.firstfloor.org/pub/ak/firescope/). On i386 it is also possible to
+use the PM_TRACE mechanism documented in Documentation/s2ram.txt .
+
+2. Testing suspend to RAM (STR)
+
+To verify that the STR works, it is generally more convenient to use the s2ram
+tool available from http://suspend.sf.net and documented at
+http://en.opensuse.org/s2ram . However, before doing that it is recommended to
+carry out the procedure described in section 1.
+
+Assume you have resolved the problems with the STD and you have found some
+failing drivers. These drivers are also likely to fail during the STR or
+during the resume, so it is better to unload them every time before the STR
+transition. Now, you can follow the instructions at
+http://en.opensuse.org/s2ram to test the system, but if it does not work
+"out of the box", you may need to boot it with "init=/bin/bash" and test
+s2ram in the minimal configuration. In that case, you may be able to search
+for failing drivers by following the procedure analogous to the one described in
+1b). If you find some failing drivers, you will have to unload them every time
+before the STR transition (ie. before you run s2ram), and please report the
+problems with them.

+Testing suspend and resume support in device drivers
+ (C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Preparing the test system
+
+Unfortunately, to effectively test the support for the system-wide suspend and
+resume transitions in a driver, it is necessary to suspend and resume a fully
+functional system with this driver loaded. Moreover, that should be done
+several times, preferably several times in a row, and separately for the suspend
+to disk (STD) and the suspend to RAM (STR) transitions, because each of these
+cases involves different ordering of operations and different interactions with
+the machine's BIOS.
+
+Of course, for this purpose the test system has to be known to suspend and
+resume without the driver being tested. Thus, if possible, you should first
+resolve all suspend/resume-related problems in the test system before you start
+testing the new driver. Please see Documents/power/basic-pm-debugging.txt for

+2. Testing the driver
+
+Once you have resolved the suspend/resume-related problems with your test system
+without the new driver, you are ready to test it:
+
+a) Build the driver as a module, load it and try the STD in the test mode (see:
+Documents/power/basic-pm-debugging.txt, 1a)).
+
+b) Load the driver and attempt to suspend to disk in the "reboot", "shutdown"
+and "platform" modes (see: Documents/power/basic-pm-debugging.txt, 1).
+
+c) Compile the driver directly into the kernel and try the STD in the test mode.
+
+d) Attempt to suspend to disk with the driver compiled directly into the kernel
+in the "reboot", "shutdown" and "platform" modes.
+
+e) Attempt to suspend to RAM using the s2ram tool with the driver loaded (see:
+Documents/power/basic-pm-debugging.txt, 2). As far as the STR tests are
+concerned, it should not matter whether or not the driver is built as a module.
+
+Each of the above tests should be repeated several times and the STD tests
+should be mixed with the STR tests. If any of them fails, the driver cannot be
+regarded as suspend/resume-safe.

+VII - Specifying interrupt information for devices
+===================================================
+
+The device tree represents the busses and devices of a hardware
+system in a form similar to the physical bus topology of the
+hardware.
+
+In addition, a logical 'interrupt tree' exists which represents the
+hierarchy and routing of interrupts in the hardware.
+
+The interrupt tree model is fully described in the
+document "Open Firmware Recommended Practice: Interrupt
+Mapping Version 0.9". The document is available at:
+<http://playground.sun.com/1275/practice>.
+
+1) interrupts property
+----------------------
+
+Devices that generate interrupts to a single interrupt controller
+should use the conventional OF representation described in the
+OF interrupt mapping documentation.
+
+Each device which generates interrupts must have an 'interrupt'
+property. The interrupt property value is an arbitrary number of
+of 'interrupt specifier' values which describe the interrupt or
+interrupts for the device.
+
+The encoding of an interrupt specifier is determined by the
+interrupt domain in which the device is located in the
+interrupt tree. The root of an interrupt domain specifies in
+its #interrupt-cells property the number of 32-bit cells
+required to encode an interrupt specifier. See the OF interrupt
+mapping documentation for a detailed description of domains.
+
+For example, the binding for the OpenPIC interrupt controller
+specifies an #interrupt-cells value of 2 to encode the interrupt
+number and level/sense information. All interrupt children in an
+OpenPIC interrupt domain use 2 cells per interrupt in their interrupts
+property.
+
+The PCI bus binding specifies a #interrupt-cell value of 1 to encode
+which interrupt pin (INTA,INTB,INTC,INTD) is used.
+
+2) interrupt-parent property
+----------------------------
+
+The interrupt-parent property is specified to define an explicit
+link between a device node and its interrupt parent in
+the interrupt tree. The value of interrupt-parent is the
+phandle of the parent node.
+
+If the interrupt-parent property is not defined for a node, it's
+interrupt parent is assumed to be an ancestor in the node's
+_device tree_ hierarchy.
+
+3) OpenPIC Interrupt Controllers
+--------------------------------
+
+OpenPIC interrupt controllers require 2 cells to encode
+interrupt information. The first cell defines the interrupt
+number. The second cell defines the sense and level
+information.
+
+Sense and level information should be encoded as follows:
+
+ 0 = low to high edge sensitive type enabled
+ 1 = active low level sensitive type enabled
+ 2 = active high level sensitive type enabled
+ 3 = high to low edge sensitive type enabled
+
+4) ISA Interrupt Controllers
+----------------------------
+
+ISA PIC interrupt controllers require 2 cells to encode
+interrupt information. The first cell defines the interrupt
+number. The second cell defines the sense and level
+information.
+
+ISA PIC interrupt controllers should adhere to the ISA PIC
+encodings listed below:
+
+ 0 = active low level sensitive type enabled
+ 1 = active high level sensitive type enabled
+ 2 = high to low edge sensitive type enabled
+ 3 = low to high edge sensitive type enabled

-crypto-API support for z990 Message Security Assist (MSA) instructions
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-AUTHOR: Thomas Spatzier (tspat@de.ibm.com)
-
-
-1. Introduction crypto-API
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-See Documentation/crypto/api-intro.txt for an introduction/description of the
-kernel crypto API.
-According to api-intro.txt support for z990 crypto instructions has been added
-in the algorithm api layer of the crypto API. Several files containing z990
-optimized implementations of crypto algorithms are placed in the
-arch/s390/crypto directory.
-
-
-2. Probing for availability of MSA
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-It should be possible to use Kernels with the z990 crypto implementations both
-on machines with MSA available and on those without MSA (pre z990 or z990
-without MSA). Therefore a simple probing mechanism has been implemented:
-In the init function of each crypto module the availability of MSA and of the
-respective crypto algorithm in particular will be tested. If the algorithm is
-available the module will load and register its algorithm with the crypto API.
-
-If the respective crypto algorithm is not available, the init function will
-return -ENOSYS. In that case a fallback to the standard software implementation
-of the crypto algorithm must be taken ( -> the standard crypto modules are
-also built when compiling the kernel).
-
-
-3. Ensuring z990 crypto module preference
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-If z990 crypto instructions are available the optimized modules should be
-preferred instead of standard modules.
-
-3.1. compiled-in modules
-~~~~~~~~~~~~~~~~~~~~~~~~
-For compiled-in modules it has to be ensured that the z990 modules are linked
-before the standard crypto modules. Then, on system startup the init functions
-of z990 crypto modules will be called first and query for availability of z990
-crypto instructions. If instruction is available, the z990 module will register
-its crypto algorithm implementation -> the load of the standard module will fail
-since the algorithm is already registered.
-If z990 crypto instruction is not available the load of the z990 module will
-fail -> the standard module will load and register its algorithm.
-
-3.2. dynamic modules
-~~~~~~~~~~~~~~~~~~~~
-A system administrator has to take care of giving preference to z990 crypto
-modules. If MSA is available appropriate lines have to be added to
-/etc/modprobe.conf.
-
-Example: z990 crypto instruction for SHA1 algorithm is available
-
- add the following line to /etc/modprobe.conf (assuming the
- z990 crypto modules for SHA1 is called sha1_z990):
-
- alias sha1 sha1_z990
-
- -> when the sha1 algorithm is requested through the crypto API
- (which has a module autoloader) the z990 module will be loaded.
-
-TBD: a userspace module probing mechanism
- something like 'probe sha1 sha1_z990 sha1' in modprobe.conf
- -> try module sha1_z990, if it fails to load standard module sha1
- the 'probe' statement is currently not supported in modprobe.conf
-
-
-4. Currently implemented z990 crypto algorithms
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The following crypto algorithms with z990 MSA support are currently implemented.
-The name of each algorithm under which it is registered in crypto API and the
-name of the respective module is given in square brackets.
-
-- SHA1 Digest Algorithm [sha1 -> sha1_z990]
-- DES Encrypt/Decrypt Algorithm (64bit key) [des -> des_z990]
-- Triple DES Encrypt/Decrypt Algorithm (128bit key) [des3_ede128 -> des_z990]
-- Triple DES Encrypt/Decrypt Algorithm (192bit key) [des3_ede -> des_z990]
-
-In order to load, for example, the sha1_z990 module when the sha1 algorithm is
-requested (see 3.2.) add 'alias sha1 sha1_z990' to /etc/modprobe.conf.

+s390 SCSI dump tool (zfcpdump)
+
+System z machines (z900 or higher) provide hardware support for creating system
+dumps on SCSI disks. The dump process is initiated by booting a dump tool, which
+has to create a dump of the current (probably crashed) Linux image. In order to
+not overwrite memory of the crashed Linux with data of the dump tool, the
+hardware saves some memory plus the register sets of the boot cpu before the
+dump tool is loaded. There exists an SCLP hardware interface to obtain the saved
+memory afterwards. Currently 32 MB are saved.
+
+This zfcpdump implementation consists of a Linux dump kernel together with
+a userspace dump tool, which are loaded together into the saved memory region
+below 32 MB. zfcpdump is installed on a SCSI disk using zipl (as contained in
+the s390-tools package) to make the device bootable. The operator of a Linux
+system can then trigger a SCSI dump by booting the SCSI disk, where zfcpdump
+resides on.
+
+The kernel part of zfcpdump is implemented as a debugfs file under "zcore/mem",
+which exports memory and registers of the crashed Linux in an s390
+standalone dump format. It can be used in the same way as e.g. /dev/mem. The
+dump format defines a 4K header followed by plain uncompressed memory. The
+register sets are stored in the prefix pages of the respective cpus. To build a
+dump enabled kernel with the zcore driver, the kernel config option
+CONFIG_ZFCPDUMP has to be set. When reading from "zcore/mem", the part of
+memory, which has been saved by hardware is read by the driver via the SCLP
+hardware interface. The second part is just copied from the non overwritten real
+memory.
+
+The userspace application of zfcpdump can reside e.g. in an intitramfs or an
+initrd. It reads from zcore/mem and writes the system dump to a file on a
+SCSI disk.
+
+To build a zfcpdump kernel use the following settings in your kernel
+configuration:
+ * CONFIG_ZFCPDUMP=y
+ * Enable ZFCP driver
+ * Enable SCSI driver
+ * Enable ext2 and ext3 filesystems
+ * Disable as many features as possible to keep the kernel small.
+ E.g. network support is not needed at all.
+
+To use the zfcpdump userspace application in an initramfs you have to do the
+following:
+
+ * Copy the zfcpdump executable somewhere into your Linux tree.
+ E.g. to "arch/s390/boot/zfcpdump. If you do not want to include
+ shared libraries, compile the tool with the "-static" gcc option.
+ * If you want to include e2fsck, add it to your source tree, too. The zfcpdump
+ application attempts to start /sbin/e2fsck from the ramdisk.
+ * Use an initramfs config file like the following:
+
+ dir /dev 755 0 0
+ nod /dev/console 644 0 0 c 5 1
+ nod /dev/null 644 0 0 c 1 3
+ nod /dev/sda1 644 0 0 b 8 1

+
+ * Issue "make image" to build the zfcpdump image with initramfs.
+
+In a Linux distribution the zfcpdump enabled kernel image must be copied to
+/usr/share/zfcpdump/zfcpdump.image, where the s390 zipl tool is looking for the
+dump kernel when preparing a SCSI dump disk.
+
+If you use a ramdisk copy it to "/usr/share/zfcpdump/zfcpdump.rd".
+
+For more information on how to use zfcpdump refer to the s390 'Using the Dump
+Tools book', which is available from

+The framework on SH extends existing API by the function clk_set_rate_ex,

+
+ clk_set_rate_ex (struct clk *clk, unsigned long rate, int algo_id)
+
+The algo_id parameter is used to specify algorithm used to recalculate clocks,

+means no changes to adjanced clock
+
+Internally, the clk_set_rate_ex forwards request to clk->ops->set_rate method,

+Some reasons you might want to use this programming interface include:
+
+ * Prototyping in an environment that's not crash-prone; stray pointers
+ in userspace won't normally bring down any Linux system.
+
+ * Developing simple protocols used to talk to microcontrollers acting
+ as SPI slaves, which you may need to change quite often.
+
+Of course there are drivers that can never be written in userspace, because
+they need to access kernel interfaces (such as IRQ handlers or other layers
+of the driver stack) that are not accessible to userspace.
+
+
+DEVICE CREATION, DRIVER BINDING
+===============================
+The simplest way to arrange to use this driver is to just list it in the
+spi_board_info for a device as the driver it should use: the "modalias"
+entry is "spidev", matching the name of the driver exposing this API.
+Set up the other device characteristics (bits per word, SPI clocking,
+chipselect polarity, etc) as usual, so you won't always need to override
+them later.
+
+(Sysfs also supports userspace driven binding/unbinding of drivers to
+devices. That mechanism might be supported here in the future.)
+
+When you do that, the sysfs node for the SPI device will include a child
+device node with a "dev" attribute that will be understood by udev or mdev.
+(Larger systems will have "udev". Smaller ones may configure "mdev" into
+busybox; it's less featureful, but often enough.) For a SPI device with
+chipselect C on bus B, you should see:
+
+ /dev/spidevB.C ... character special device, major number 153 with
+ a dynamically chosen minor device number. This is the node
+ that userspace programs will open, created by "udev" or "mdev".
+
+ /sys/devices/.../spiB.C ... as usual, the SPI device node will
+ be a child of its SPI master controller.
+
+ /sys/class/spidev/spidevB.C ... created when the "spidev" driver
+ binds to that device. (Directory or symlink, based on whether
+ or not you enabled the "deprecated sysfs files" Kconfig option.)
+
+Do not try to manage the /dev character device special file nodes by hand.
+That's error prone, and you'd need to pay careful attention to system
+security issues; udev/mdev should already be configured securely.
+
+If you unbind the "spidev" driver from that device, those two "spidev" nodes
+(in sysfs and in /dev) should automatically be removed (respectively by the
+kernel and by udev/mdev). You can unbind by removing the "spidev" driver
+module, which will affect all devices using this driver. You can also unbind
+by having kernel code remove the SPI device, probably by removing the driver
+for its SPI controller (so its spi_master vanishes).
+
+Since this is a standard Linux device driver -- even though it just happens
+to expose a low level API to userspace -- it can be associated with any number
+of devices at a time. Just provide one spi_board_info record for each such
+SPI device, and you'll get a /dev device node for each device.
+
+
+BASIC CHARACTER DEVICE API
+==========================
+Normal open() and close() operations on /dev/spidevB.D files work as you
+would expect.
+
+Standard read() and write() operations are obviously only half-duplex, and
+the chipselect is deactivated between those operations. Full-duplex access,
+and composite operation without chipselect de-activation, is available using
+the SPI_IOC_MESSAGE(N) request.
+
+Several ioctl() requests let your driver read or override the device's current
+settings for data transfer parameters:
+
+ SPI_IOC_RD_MODE, SPI_IOC_WR_MODE ... pass a pointer to a byte which will
+ return (RD) or assign (WR) the SPI transfer mode. Use the constants
+ SPI_MODE_0..SPI_MODE_3; or if you prefer you can combine SPI_CPOL
+ (clock polarity, idle high iff this is set) or SPI_CPHA (clock phase,
+ sample on trailing edge iff this is set) flags.
+
+ SPI_IOC_RD_LSB_FIRST, SPI_IOC_WR_LSB_FIRST ... pass a pointer to a byte
+ which will return (RD) or assign (WR) the bit justification used to
+ transfer SPI words. Zero indicates MSB-first; other values indicate
+ the less common LSB-first encoding. In both cases the specified value
+ is right-justified in each word, so that unused (TX) or undefined (RX)
+ bits are in the MSBs.
+
+ SPI_IOC_RD_BITS_PER_WORD, SPI_IOC_WR_BITS_PER_WORD ... pass a pointer to
+ a byte which will return (RD) or assign (WR) the number of bits in
+ each SPI transfer word. The value zero signifies eight bits.
+
+ SPI_IOC_RD_MAX_SPEED_HZ, SPI_IOC_WR_MAX_SPEED_HZ ... pass a pointer to a
+ u32 which will return (RD) or assign (WR) the maximum SPI transfer
+ speed, in Hz. The controller can't necessarily assign that specific
+ clock speed.
+
+NOTES:
+
+ - At this time there is no async I/O support; everything is purely
+ synchronous.
+
+ - There's currently no way to report the actual bit rate used to
+ shift data to/from a given device.
+
+ - From userspace, you can't currently change the chip select polarity;
+ that could corrupt transfers to other devices sharing the SPI bus.
+ Each SPI device is deselected when it's not in active use, allowing
+ other drivers to talk to other devices.
+
+ - There's a limit on the number of bytes each I/O request can transfer
+ to the SPI device. It defaults to one page, but that can be changed
+ using a module parameter.
+
+ - Because SPI has no low-level transfer acknowledgement, you usually
+ won't see any I/O errors when talking to a non-existent device.
+
+
+FULL DUPLEX CHARACTER DEVICE API
+================================
+
+See the sample program below for one example showing the use of the full
+duplex programming interface. (Although it doesn't perform a full duplex
+transfer.) The model is the same as that used in the kernel spi_sync()
+request; the individual transfers offer the same capabilities as are
+available to kernel drivers (except that it's not asynchronous).
+
+The example shows one half-duplex RPC-style request and response message.
+These requests commonly require that the chip not be deselected between
+the request and response. Several such requests could be chained into
+a single kernel request, even allowing the chip to be deselected after
+each response. (Other protocol options include changing the word size
+and bitrate for each transfer segment.)
+
+To make a full duplex request, provide both rx_buf and tx_buf for the
+same transfer. It's even OK if those are the same buffer.

------------
If you are compiling this driver as included in the Linux kernel
-sources, simply enable the CONFIG_ACPI_IBM option (Power Management /
-ACPI / IBM ThinkPad Laptop Extras).
+sources, simply enable the CONFIG_THINKPAD_ACPI option, and optionally
+enable the CONFIG_THINKPAD_ACPI_BAY option if you want the
+thinkpad-specific bay functionality.
Features
--------
-The driver creates the /proc/acpi/ibm directory. There is a file under
-that directory for each feature described below. Note that while the
-driver is still in the alpha stage, the exact proc file format and
-commands supported by the various features is guaranteed to change
-frequently.
+The driver exports two different interfaces to userspace, which can be
+used to access the features it provides. One is a legacy procfs-based
+interface, which will be removed at some time in the distant future.
+The other is a new sysfs-based interface which is not complete yet.
-Driver version -- /proc/acpi/ibm/driver
----------------------------------------
+The procfs interface creates the /proc/acpi/ibm directory. There is a
+file under that directory for each feature it supports. The procfs
+interface is mostly frozen, and will change very little if at all: it
+will not be extended to add any new functionality in the driver, instead
+all new functionality will be implemented on the sysfs interface.
+
+The sysfs interface tries to blend in the generic Linux sysfs subsystems
+and classes as much as possible. Since some of these subsystems are not
+yet ready or stabilized, it is expected that this interface will change,
+and any and all userspace programs must deal with it.
+
+
+Notes about the sysfs interface:
+
+Unlike what was done with the procfs interface, correctness when talking
+to the sysfs interfaces will be enforced, as will correctness in the
+thinkpad-acpi's implementation of sysfs interfaces.
+
+Also, any bugs in the thinkpad-acpi sysfs driver code or in the
+thinkpad-acpi's implementation of the sysfs interfaces will be fixed for
+maximum correctness, even if that means changing an interface in
+non-compatible ways. As these interfaces mature both in the kernel and
+in thinkpad-acpi, such changes should become quite rare.
+
+Applications interfacing to the thinkpad-acpi sysfs interfaces must
+follow all sysfs guidelines and correctly process all errors (the sysfs
+interface makes extensive use of errors). File descriptors and open /
+close operations to the sysfs inodes must also be properly implemented.
+
+The version of thinkpad-acpi's sysfs interface is exported by the driver
+as a driver attribute (see below).
+
+Sysfs driver attributes are on the driver's sysfs attribute space,
+for 2.6.20 this is /sys/bus/platform/drivers/thinkpad-acpi/.

-Interval is the ammount of time in seconds to wait for one of the

-Example Configuration
----------------------
-
-The ACPI support in the kernel is intended to be used in conjunction
-with a user-space daemon, acpid. The configuration files for this
-daemon control what actions are taken in response to various ACPI
-events. An example set of configuration files are included in the
-config/ directory of the tarball package available on the web
-site. Note that these are provided for illustration purposes only and
-may need to be adapted to your particular setup.
-
-The following utility scripts are used by the example action
-scripts (included with ibm-acpi for completeness):
-
- /usr/local/sbin/idectl -- from the hdparm source distribution,
- see http://www.ibiblio.org/pub/Linux/system/hardware
- /usr/local/sbin/laptop_mode -- from the Linux kernel source
- distribution, see Documentation/laptop-mode.txt
- /sbin/service -- comes with Redhat/Fedora distributions
- /usr/sbin/hibernate -- from the Software Suspend 2 distribution,
- see http://softwaresuspend.berlios.de/
-
-Toan T Nguyen <ntt@physics.ucla.edu> notes that Suse uses the
-powersave program to suspend ('powersave --suspend-to-ram') or
-hibernate ('powersave --suspend-to-disk'). This means that the
-hibernate script is not needed on that distribution.
-
-Henrik Brix Andersen <brix@gentoo.org> has written a Gentoo ACPI event
-handler script for the X31. You can get the latest version from
-http://dev.gentoo.org/~brix/files/x31.sh
-
-David Schweikert <dws@ee.eth.ch> has written an alternative blank.sh
-script which works on Debian systems. This scripts has now been
-extended to also work on Fedora systems and included as the default
-blank.sh in the distribution.
+Commands can also be specified when loading the thinkpad-acpi module,
+for example:
+
+ modprobe thinkpad_acpi hotkey=enable,0xffff video=auto_disable
+
+Enabling debugging output
+-------------------------
+
+The module takes a debug paramater which can be used to selectively
+enable various classes of debugging output, for example:
+
+ modprobe ibm_acpi debug=0xffff
+
+will enable all debugging output classes. It takes a bitmask, so
+to enable more than one output class, just add their values.
+
+ Debug bitmask Description
+ 0x0001 Initialization and probing
+ 0x0002 Removal
+
+There is also a kernel build option to enable more debugging
+information, which may be necessary to debug driver problems.
+
+The level of debugging information output by the driver can be changed
+at runtime through sysfs, using the driver attribute debug_level. The
+attribute takes the same bitmask as the debug module parameter above.
+
+Force loading of module
+-----------------------
+
+If thinkpad-acpi refuses to detect your ThinkPad, you can try to specify
+the module parameter force_load=1. Regardless of whether this works or
+not, please contact ibm-acpi-devel@lists.sourceforge.net with a report.

* Raw text data format
-The '1t' type data consists of a stream of events, such as URB submission,
+Two formats are supported currently: the original, or '1t' format, and
+the '1u' format. The '1t' format is deprecated in kernel 2.6.21. The '1u'
+format adds a few fields, such as ISO frame descriptors, interval, etc.
+It produces slightly longer lines, but otherwise is a perfect superset
+of '1t' format.
+
+If it is desired to recognize one from the other in a program, look at the
+"address" word (see below), where '1u' format adds a bus number. If 2 colons
+are present, it's the '1t' format, otherwise '1u'.
+
+Any text format data consists of a stream of events, such as URB submission,
URB callback, submission error. Every event is a text line, which consists
of whitespace separated words. The number or position of words may depend
on the event type, but there is a set of words, common for all types.
Here is the list of words, from left to right:
+
- URB Tag. This is used to identify URBs is normally a kernel mode address
of the URB structure in hexadecimal.
+
- Timestamp in microseconds, a decimal number. The timestamp's resolution
depends on available clock, and so it can be much worse than a microsecond
(if the implementation uses jiffies, for example).
+
- Event Type. This type refers to the format of the event, not URB type.
Available types are: S - submission, C - callback, E - submission error.
-- "Pipe". The pipe concept is deprecated. This is a composite word, used to
- be derived from information in pipes. It consists of three fields, separated
- by colons: URB type and direction, Device address, Endpoint number.
+
+- "Address" word (formerly a "pipe"). It consists of four fields, separated by
+ colons: URB type and direction, Bus number, Device address, Endpoint number.
Type and direction are encoded with two bytes in the following manner:
Ci Co Control input and output
Zi Zo Isochronous input and output
Ii Io Interrupt input and output
Bi Bo Bulk input and output
- Device address and Endpoint number are 3-digit and 2-digit (respectively)
- decimal numbers, with leading zeroes.
-- URB Status. In most cases, this field contains a number, sometimes negative,
- which represents a "status" field of the URB. This field makes no sense for
- submissions, but is present anyway to help scripts with parsing. When an
- error occurs, the field contains the error code. In case of a submission of
- a Control packet, this field contains a Setup Tag instead of an error code.
- It is easy to tell whether the Setup Tag is present because it is never a
- number. Thus if scripts find a number in this field, they proceed to read
- Data Length. If they find something else, like a letter, they read the setup
- packet before reading the Data Length.
+ Bus number, Device address, and Endpoint are decimal numbers, but they may
+ have leading zeros, for the sake of human readers.
+
+- URB Status word. This is either a letter, or several numbers separated
+ by colons: URB status, interval, start frame, and error count. Unlike the
+ "address" word, all fields save the status are optional. Interval is printed
+ only for interrupt and isochronous URBs. Start frame is printed only for
+ isochronous URBs. Error count is printed only for isochronous callback
+ events.
+
+ The status field is a decimal number, sometimes negative, which represents
+ a "status" field of the URB. This field makes no sense for submissions, but
+ is present anyway to help scripts with parsing. When an error occurs, the
+ field contains the error code.
+
+ In case of a submission of a Control packet, this field contains a Setup Tag
+ instead of an group of numbers. It is easy to tell whether the Setup Tag is
+ present because it is never a number. Thus if scripts find a set of numbers
+ in this word, they proceed to read Data Length (except for isochronous URBs).
+ If they find something else, like a letter, they read the setup packet before
+ reading the Data Length or isochronous descriptors.
+
- Setup packet, if present, consists of 5 words: one of each for bmRequestType,
bRequest, wValue, wIndex, wLength, as specified by the USB Specification 2.0.
These words are safe to decode if Setup Tag was 's'. Otherwise, the setup
packet was present, but not captured, and the fields contain filler.
+
+- Number of isochronous frame descriptors and descriptors themselves.
+ If an Isochronous transfer event has a set of descriptors, a total number
+ of them in an URB is printed first, then a word per descriptor, up to a
+ total of 5. The word consists of 3 colon-separated decimal numbers for
+ status, offset, and length respectively. For submissions, initial length
+ is reported. For callbacks, actual length is reported.
+
- Data Length. For submissions, this is the requested length. For callbacks,
this is the actual length.
+
- Data tag. The usbmon may not always capture data, even if length is nonzero.
The data words are present only if this tag is '='.
+
- Data words follow, in big endian hexadecimal format. Notice that they are
not machine words, but really just a byte stream split into words to make
it easier to read. Thus, the last word may contain from one to four bytes.

+ivtv release notes
+==================
+
+This is a v4l2 device driver for the Conexant cx23415/6 MPEG encoder/decoder.
+The cx23415 can do both encoding and decoding, the cx23416 can only do MPEG
+encoding. Currently the only card featuring full decoding support is the
+Hauppauge PVR-350.
+
+NOTE: this driver requires the latest encoder firmware (version 2.06.039, size
+376836 bytes). Get the firmware from here:
+
+http://dl.ivtvdriver.org/ivtv/firmware/firmware.tar.gz
+
+NOTE: 'normal' TV applications do not work with this driver, you need
+an application that can handle MPEG input such as mplayer, xine, MythTV,
+etc.
+
+The primary goal of the IVTV project is to provide a "clean room" Linux
+Open Source driver implementation for video capture cards based on the
+iCompression iTVC15 or Conexant CX23415/CX23416 MPEG Codec.
+
+Features:
+ * Hardware mpeg2 capture of broadcast video (and sound) via the tuner or
+ S-Video/Composite and audio line-in.
+ * Hardware mpeg2 capture of FM radio where hardware support exists
+ * Supports NTSC, PAL, SECAM with stereo sound
+ * Supports SAP and bilingual transmissions.
+ * Supports raw VBI (closed captions and teletext).
+ * Supports sliced VBI (closed captions and teletext) and is able to insert
+ this into the captured MPEG stream.
+ * Supports raw YUV and PCM input.
+
+Additional features for the PVR-350 (CX23415 based):
+ * Provides hardware mpeg2 playback
+ * Provides comprehensive OSD (On Screen Display: ie. graphics overlaying the
+ video signal)
+ * Provides a framebuffer (allowing X applications to appear on the video
+ device) (this framebuffer is not yet part of the kernel. In the meantime it
+ is available from www.ivtvdriver.org).
+ * Supports raw YUV output.
+
+IMPORTANT: In case of problems first read this page:
+ http://www.ivtvdriver.org/index.php/Troubleshooting

+
+Devices
+=======
+
+A maximum of 12 ivtv boards are allowed at the moment.
+
+Cards that don't have a video output capability (i.e. non PVR350 cards)
+lack the vbi8, vbi16, video16 and video48 devices. They also do not
+support the framebuffer device /dev/fbx for OSD.
+
+The radio0 device may or may not be present, depending on whether the
+card has a radio tuner or not.
+
+Here is a list of the base v4l devices:
+crw-rw---- 1 root video 81, 0 Jun 19 22:22 /dev/video0
+crw-rw---- 1 root video 81, 16 Jun 19 22:22 /dev/video16
+crw-rw---- 1 root video 81, 24 Jun 19 22:22 /dev/video24
+crw-rw---- 1 root video 81, 32 Jun 19 22:22 /dev/video32
+crw-rw---- 1 root video 81, 48 Jun 19 22:22 /dev/video48
+crw-rw---- 1 root video 81, 64 Jun 19 22:22 /dev/radio0
+crw-rw---- 1 root video 81, 224 Jun 19 22:22 /dev/vbi0
+crw-rw---- 1 root video 81, 228 Jun 19 22:22 /dev/vbi8
+crw-rw---- 1 root video 81, 232 Jun 19 22:22 /dev/vbi16
+
+Base devices
+============
+
+For every extra card you have the numbers increased by one. For example,
+/dev/video0 is listed as the 'base' encoding capture device so we have:
+
+ /dev/video0 is the encoding capture device for the first card (card 0)
+ /dev/video1 is the encoding capture device for the second card (card 1)
+ /dev/video2 is the encoding capture device for the third card (card 2)
+
+Note that if the first card doesn't have a feature (eg no decoder, so no
+video16, the second card will still use video17. The simple rule is 'add
+the card number to the base device number'. If you have other capture
+cards (e.g. WinTV PCI) that are detected first, then you have to tell
+the ivtv module about it so that it will start counting at 1 (or 2, or
+whatever). Otherwise the device numbers can get confusing. The ivtv
+'ivtv_first_minor' module option can be used for that.
+
+
+/dev/video0
+The encoding capture device(s).
+Read-only.
+
+Reading from this device gets you the MPEG1/2 program stream.
+Example:
+
+cat /dev/video0 > my.mpg (you need to hit ctrl-c to exit)
+
+
+/dev/video16
+The decoder output device(s)
+Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+An mpeg2 stream sent to this device will appear on the selected video
+display, audio will appear on the line-out/audio out. It is only
+available for cards that support video out. Example:
+
+cat my.mpg >/dev/video16
+
+
+/dev/video24
+The raw audio capture device(s).
+Read-only
+
+The raw audio PCM stereo stream from the currently selected
+tuner or audio line-in. Reading from this device results in a raw
+(signed 16 bit Little Endian, 48000 Hz, stereo pcm) capture.
+This device only captures audio. This should be replaced by an ALSA
+device in the future.
+Note that there is no corresponding raw audio output device, this is
+not supported in the decoder firmware.
+
+
+/dev/video32
+The raw video capture device(s)
+Read-only
+
+The raw YUV video output from the current video input. The YUV format
+is non-standard (V4L2_PIX_FMT_HM12).
+
+Note that the YUV and PCM streams are not synchronized, so they are of
+limited use.
+
+
+/dev/video48
+The raw video display device(s)
+Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+Writes a YUV stream to the decoder of the card.
+
+
+/dev/radio0
+The radio tuner device(s)
+Cannot be read or written.
+
+Used to enable the radio tuner and tune to a frequency. You cannot
+read or write audio streams with this device. Once you use this
+device to tune the radio, use /dev/video24 to read the raw pcm stream
+or /dev/video0 to get an mpeg2 stream with black video.
+
+
+/dev/vbi0
+The 'vertical blank interval' (Teletext, CC, WSS etc) capture device(s)
+Read-only
+
+Captures the raw (or sliced) video data sent during the Vertical Blank
+Interval. This data is used to encode teletext, closed captions, VPS,
+widescreen signalling, electronic program guide information, and other
+services.
+
+
+/dev/vbi8
+Processed vbi feedback device(s)
+Read-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+The sliced VBI data embedded in an MPEG stream is reproduced on this
+device. So while playing back a recording on /dev/video16, you can
+read the embedded VBI data from /dev/vbi8.
+
+
+/dev/vbi16
+The vbi 'display' device(s)
+Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+Can be used to send sliced VBI data to the video-out connector.

+Zoran 364xx based USB webcam module version 0.72
+site: http://royale.zerezo.com/zr364xx/
+mail: royale@zerezo.com
+
+introduction:
+This brings support under Linux for the Aiptek PocketDV 3300 in webcam mode.
+If you just want to get on your PC the pictures and movies on the camera, you should use the usb-storage module instead.
+The driver works with several other cameras in webcam mode (see the list below).
+Maybe this code can work for other JPEG/USB cams based on the Coach chips from Zoran?
+Possible chipsets are : ZR36430 (ZR36430BGC) and maybe ZR36431, ZR36440, ZR36442...
+You can try the experience changing the vendor/product ID values (look at the source code).
+You can get these values by looking at /var/log/messages when you plug your camera, or by typing : cat /proc/bus/usb/devices.
+If you manage to use your cam with this code, you can send me a mail (royale@zerezo.com) with the name of your cam and a patch if needed.
+This is a beta release of the driver.
+Since version 0.70, this driver is only compatible with V4L2 API and 2.6.x kernels.
+If you need V4L1 or 2.4x kernels support, please use an older version, but the code is not maintained anymore.
+Good luck!
+
+install:
+In order to use this driver, you must compile it with your kernel.
+Location: Device Drivers -> Multimedia devices -> Video For Linux -> Video Capture Adapters -> V4L USB devices
+
+usage:
+modprobe zr364xx debug=X mode=Y
+ - debug : set to 1 to enable verbose debug messages
+ - mode : 0 = 320x240, 1 = 160x120, 2 = 640x480
+You can then use the camera with V4L2 compatible applications, for example Ekiga.
+To capture a single image, try this: dd if=/dev/video0 of=test.jpg bs=1 count=1
+
+links :
+http://mxhaard.free.fr/ (support for many others cams including some Aiptek PocketDV)

+Short users guide for SLUB
+--------------------------
+
+First of all slub should transparently replace SLAB. If you enable
+SLUB then everything should work the same (Note the word "should".
+There is likely not much value in that word at this point).
+
+The basic philosophy of SLUB is very different from SLAB. SLAB
+requires rebuilding the kernel to activate debug options for all
+SLABS. SLUB always includes full debugging but its off by default.
+SLUB can enable debugging only for selected slabs in order to avoid
+an impact on overall system performance which may make a bug more
+difficult to find.
+
+In order to switch debugging on one can add a option "slub_debug"
+to the kernel command line. That will enable full debugging for
+all slabs.
+
+Typically one would then use the "slabinfo" command to get statistical
+data and perform operation on the slabs. By default slabinfo only lists
+slabs that have data in them. See "slabinfo -h" for more options when
+running the command. slabinfo can be compiled with
+
+gcc -o slabinfo Documentation/vm/slabinfo.c
+
+Some of the modes of operation of slabinfo require that slub debugging
+be enabled on the command line. F.e. no tracking information will be
+available without debugging on and validation can only partially
+be performed if debugging was not switched on.
+
+Some more sophisticated uses of slub_debug:
+-------------------------------------------
+
+Parameters may be given to slub_debug. If none is specified then full
+debugging is enabled. Format:
+
+slub_debug=<Debug-Options> Enable options for all slabs
+slub_debug=<Debug-Options>,<slab name>
+ Enable options only for select slabs
+
+Possible debug options are
+ F Sanity checks on (enables SLAB_DEBUG_FREE. Sorry
+ SLAB legacy issues)
+ Z Red zoning
+ P Poisoning (object and padding)
+ U User tracking (free and alloc)
+ T Trace (please only use on single slabs)
+
+F.e. in order to boot just with sanity checks and red zoning one would specify:
+
+ slub_debug=FZ
+
+Trying to find an issue in the dentry cache? Try
+
+ slub_debug=,dentry_cache
+
+to only enable debugging on the dentry cache.
+
+Red zoning and tracking may realign the slab. We can just apply sanity checks
+to the dentry cache with
+
+ slub_debug=F,dentry_cache
+
+In case you forgot to enable debugging on the kernel command line: It is
+possible to enable debugging manually when the kernel is up. Look at the
+contents of:
+
+/sys/slab/<slab name>/
+
+Look at the writable files. Writing 1 to them will enable the
+corresponding debug option. All options can be set on a slab that does
+not contain objects. If the slab already contains objects then sanity checks
+and tracing may only be enabled. The other options may cause the realignment
+of objects.
+
+Careful with tracing: It may spew out lots of information and never stop if
+used on the wrong slab.
+
+SLAB Merging
+------------
+
+If no debugging is specified then SLUB may merge similar slabs together
+in order to reduce overhead and increase cache hotness of objects.
+slabinfo -a displays which slabs were merged together.
+
+Getting more performance
+------------------------
+
+To some degree SLUB's performance is limited by the need to take the
+list_lock once in a while to deal with partial slabs. That overhead is
+governed by the order of the allocation for each slab. The allocations
+can be influenced by kernel parameters:
+
+slub_min_objects=x (default 8)
+slub_min_order=x (default 0)
+slub_max_order=x (default 4)
+
+slub_min_objects allows to specify how many objects must at least fit
+into one slab in order for the allocation order to be acceptable.
+In general slub will be able to perform this number of allocations
+on a slab without consulting centralized resources (list_lock) where
+contention may occur.
+
+slub_min_order specifies a minim order of slabs. A similar effect like
+slub_min_objects.
+
+slub_max_order specified the order at which slub_min_objects should no
+longer be checked. This is useful to avoid SLUB trying to generate
+super large order pages to fit slub_min_objects of a slab cache with
+large object sizes into one high order page.

+Using numa=fake and CPUSets for Resource Management
+Written by David Rientjes <rientjes@cs.washington.edu>
+
+This document describes how the numa=fake x86_64 command-line option can be used
+in conjunction with cpusets for coarse memory management. Using this feature,
+you can create fake NUMA nodes that represent contiguous chunks of memory and
+assign them to cpusets and their attached tasks. This is a way of limiting the
+amount of system memory that are available to a certain class of tasks.
+
+For more information on the features of cpusets, see Documentation/cpusets.txt.
+There are a number of different configurations you can use for your needs. For
+more information on the numa=fake command line option and its various ways of
+configuring fake nodes, see Documentation/x86_64/boot-options.txt.
+
+For the purposes of this introduction, we'll assume a very primitive NUMA
+emulation setup of "numa=fake=4*512,". This will split our system memory into
+four equal chunks of 512M each that we can now use to assign to cpusets. As
+you become more familiar with using this combination for resource control,
+you'll determine a better setup to minimize the number of nodes you have to deal
+with.
+
+A machine may be split as follows with "numa=fake=4*512," as reported by dmesg:
+
+ Faking node 0 at 0000000000000000-0000000020000000 (512MB)
+ Faking node 1 at 0000000020000000-0000000040000000 (512MB)
+ Faking node 2 at 0000000040000000-0000000060000000 (512MB)
+ Faking node 3 at 0000000060000000-0000000080000000 (512MB)
+ ...
+ On node 0 totalpages: 130975
+ On node 1 totalpages: 131072
+ On node 2 totalpages: 131072
+ On node 3 totalpages: 131072
+
+Now following the instructions for mounting the cpusets filesystem from
+Documentation/cpusets.txt, you can assign fake nodes (i.e. contiguous memory
+address spaces) to individual cpusets:
+
+ [root@xroads /]# mkdir exampleset
+ [root@xroads /]# mount -t cpuset none exampleset
+ [root@xroads /]# mkdir exampleset/ddset
+ [root@xroads /]# cd exampleset/ddset
+ [root@xroads /exampleset/ddset]# echo 0-1 > cpus
+ [root@xroads /exampleset/ddset]# echo 0-1 > mems
+
+Now this cpuset, 'ddset', will only allowed access to fake nodes 0 and 1 for
+memory allocations (1G).
+
+You can now assign tasks to these cpusets to limit the memory resources
+available to them according to the fake nodes assigned as mems:
+
+ [root@xroads /exampleset/ddset]# echo $$ > tasks
+ [root@xroads /exampleset/ddset]# dd if=/dev/zero of=tmp bs=1024 count=1G
+ [1] 13425
+
+Notice the difference between the system memory usage as reported by
+/proc/meminfo between the restricted cpuset case above and the unrestricted
+case (i.e. running the same 'dd' command without assigning it to a fake NUMA
+cpuset):
+ Unrestricted Restricted
+ MemTotal: 3091900 kB 3091900 kB
+ MemFree: 42113 kB 1513236 kB
+
+This allows for coarse memory management for the tasks you assign to particular
+cpusets. Since cpusets can form a hierarchy, you can create some pretty
+interesting combinations of use-cases for various classes of tasks for your
+memory management needs.

+ * - The parentheses on the keypad send '(' and ')' with all

+ * - HELP and UNDO are mapped to be F21 and F24, resp, that send the

+ * F11 and F12, because these codes are on Shift+F1/2 anyway.) This
+ * way, applications that allow their own keyboard mappings
+ * (e.g. tcsh, X Windows) can be configured to use them in the way
+ * the label suggests (providing help or undoing).
+ *
+ * - Console switching is done with Alt+Fx (consoles 1..10) and
+ * Shift+Alt+Fx (consoles 11..20).
+ *
+ * - The misc. special function implemented in the kernel are mapped
+ * to the following key combinations:
+ *
+ * ClrHome -> Home/Find
+ * Shift + ClrHome -> End/Select
+ * Shift + Up -> Page Up
+ * Shift + Down -> Page Down
+ * Alt + Help -> show system status
+ * Shift + Help -> show memory info
+ * Ctrl + Help -> show registers
+ * Ctrl + Alt + Del -> Reboot
+ * Alt + Undo -> switch to last console
+ * Shift + Undo -> send interrupt
+ * Alt + Insert -> stop/start output (same as ^S/^Q)
+ * Alt + Up -> Scroll back console (if implemented)
+ * Alt + Down -> Scroll forward console (if implemented)
+ * Alt + CapsLock -> NumLock

- temperature within 2-4 degrees Celsius. This option shows the current
- on-die temperature in /proc/cpuinfo if the cpu supports it.
-
- Unfortunately, on some chip revisions, this sensor is very inaccurate

-config TAU_INT

- ---help---
- The TAU supports an interrupt driven mode which causes an interrupt
- whenever the temperature goes out of range. This is the fastest way
- to get notified the temp has exceeded a range. With this option off,
- a timer is used to re-check the temperature periodically.
-
- However, on some cpus it appears that the TAU interrupt hardware
- is buggy and can cause a situation which would lead unexplained hard
- lockups.
-
- Unless you are extending the TAU driver, or enjoy kernel/hardware
- debugging, leave this option off.
-
-config TAU_AVERAGE
- bool "Average high and low temp"
- depends on TAU
- ---help---
- The TAU hardware can compare the temperature to an upper and lower
- bound. The default behavior is to show both the upper and lower
- bound in /proc/cpuinfo. If the range is large, the temperature is
- either changing a lot, or the TAU hardware is broken (likely on some
- G4's). If the range is small (around 4 degrees), the temperature is
- relatively stable. If you say Y here, a single temperature value,
- halfway between the upper and lower bounds, will be reported in
- /proc/cpuinfo.
-
- If in doubt, say N here.

+ temperature within 2-4 degrees Celsius. This option shows the current
+ on-die temperature in /proc/cpuinfo if the cpu supports it.

+ The TAU supports an interrupt driven mode which causes an interrupt

+ to get notified the temp has exceeded a range. With this option off,
+ a timer is used to re-check the temperature periodically.
+
+ However, on some cpus it appears that the TAU interrupt hardware
+ is buggy and can cause a situation which would lead unexplained hard
+ lockups.
+
+ Unless you are extending the TAU driver, or enjoy kernel/hardware
+ debugging, leave this option off.
+
+config TAU_AVERAGE
+ bool "Average high and low temp"
+ depends on TAU
+ ---help---
+ The TAU hardware can compare the temperature to an upper and lower
+ bound. The default behavior is to show both the upper and lower
+ bound in /proc/cpuinfo. If the range is large, the temperature is
+ either changing a lot, or the TAU hardware is broken (likely on some
+ G4's). If the range is small (around 4 degrees), the temperature is
+ relatively stable. If you say Y here, a single temperature value,
+ halfway between the upper and lower bounds, will be reported in

/*
* thermal support for the cell processor
*
+ * This module adds some sysfs attributes to cpu and spu nodes.
+ * Base for measurements are the digital thermal sensors (DTS)
+ * located on the chip.
+ * The accuracy is 2 degrees, starting from 65 up to 125 degrees celsius
+ * The attributes can be found under
+ * /sys/devices/system/cpu/cpuX/thermal
+ * /sys/devices/system/spu/spuX/thermal
+ *
+ * The following attributes are added for each node:
+ * temperature:
+ * contains the current temperature measured by the DTS
+ * throttle_begin:
+ * throttling begins when temperature is greater or equal to
+ * throttle_begin. Setting this value to 125 prevents throttling.
+ * throttle_end:
+ * throttling is being ceased, if the temperature is lower than
+ * throttle_end. Due to a delay between applying throttling and
+ * a reduced temperature this value should be less than throttle_begin.
+ * A value equal to throttle_begin provides only a very little hysteresis.
+ * throttle_full_stop:
+ * If the temperatrue is greater or equal to throttle_full_stop,
+ * full throttling is applied to the cpu or spu. This value should be
+ * greater than throttle_begin and throttle_end. Setting this value to
+ * 65 prevents the unit from running code at all.

-/* ++TeSche: radically changed for new expanding purposes...
- *
- * These two routines now deal with copying/expanding/translating the samples
- * from user space into our buffer at the right frequency. They take care about
- * how much data there's actually to read, how much buffer space there is and
- * to convert samples into the right frequency/encoding. They will only work on
- * complete samples so it may happen they leave some bytes in the input stream
- * if the user didn't write a multiple of the current sample size. They both
- * return the number of bytes they've used from both streams so you may detect
- * such a situation. Luckily all programs should be able to cope with that.
- *
- * I think I've optimized anything as far as one can do in plain C, all
- * variables should fit in registers and the loops are really short. There's
- * one loop for every possible situation. Writing a more generalized and thus
- * parameterized loop would only produce slower code. Feel free to optimize
- * this in assembler if you like. :)
- *
- * I think these routines belong here because they're not yet really hardware
- * independent, especially the fact that the Falcon can play 16bit samples
- * only in stereo is hardcoded in both of them!
- *
- * ++geert: split in even more functions (one per format)

+ * It has 3 IRQ lines which trigger 10 events, and works independently
+ * from the traditional SH DMAC (although it blocks usage of DMAC 0)

- This gives the physical address where the kernel is loaded. Normally
- for regular kernels this value is 0x200000 (2MB). But in the case
- of kexec on panic the fail safe kernel needs to run at a different
- address than the panic-ed kernel. This option is used to set the load
- address for kernels used to capture crash dump on being kexec'ed
- after panic. The default value for crash dump kernels is
- 0x1000000 (16MB). This can also be set based on the "X" value as
+ This gives the physical address where the kernel is loaded. It
+ should be aligned to 2MB boundary.
+
+ If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
+ bzImage will decompress itself to above physical address and
+ run from there. Otherwise, bzImage will run from the address where
+ it has been loaded by the boot loader and will ignore above physical
+ address.
+
+ In normal kdump cases one does not have to set/change this option
+ as now bzImage can be compiled as a completely relocatable image
+ (CONFIG_RELOCATABLE=y) and be used to load and run from a different
+ address. This option is mainly useful for the folks who don't want
+ to use a bzImage for capturing the crash dump and want to use a
+ vmlinux instead.
+
+ So if you are using bzImage for capturing the crash dump, leave
+ the value here unchanged to 0x200000 and set CONFIG_RELOCATABLE=y.
+ Otherwise if you plan to use vmlinux for capturing the crash dump
+ change this value to start of the reserved region (Typically 16MB
+ 0x1000000). In other words, it can be set based on the "X" value as
specified in the "crashkernel=YM@XM" command line boot parameter
passed to the panic-ed kernel. Typically this parameter is set as
crashkernel=64M@16M. Please take a look at
Documentation/kdump/kdump.txt for more details about crash dumps.
+ Usage of bzImage for capturing the crash dump is advantageous as
+ one does not have to build two kernels. Same kernel can be used
+ as production kernel and capture kernel.

+ * The buffer for decompression in place is the length of the
+ * uncompressed data, plus a small amount extra to keep the algorithm safe.
+ * The compressed data is placed at the end of the buffer. The output
+ * pointer is placed at the start of the buffer and the input pointer
+ * is placed where the compressed data starts. Problems will occur
+ * when the output pointer overruns the input pointer.
+ *
+ * The output pointer can only overrun the input pointer if the input
+ * pointer is moving faster than the output pointer. A condition only
+ * triggered by data whose compressed form is larger than the uncompressed
+ * form.
+ *
+ * The worst case at the block level is a growth of the compressed data
+ * of 5 bytes per 32767 bytes.
+ *
+ * The worst case internal to a compressed block is very hard to figure.
+ * The worst case can at least be boundined by having one bit that represents
+ * 32764 bytes and then all of the rest of the bytes representing the very
+ * very last byte.
+ *
+ * All of which is enough to compute an amount of extra data that is required
+ * to be safe. To avoid problems at the block level allocating 5 extra bytes
+ * per 32767 bytes of data is sufficient. To avoind problems internal to a block
+ * adding an extra 32767 bytes (the worst case uncompressed block size) is
+ * sufficient, to ensure that in the worst case the decompressed data for
+ * block will stop the byte before the compressed data for a block begins.
+ * To avoid problems with the compressed data's meta information an extra 18
+ * bytes are needed. Leading to the formula:
+ *
+ * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
+ *
+ * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
+ * Adding 32768 instead of 32767 just makes for round numbers.
+ * Adding the decompressor_size is necessary as it musht live after all
+ * of the data as well. Last I measured the decompressor is about 14K.
+ * 10K of actuall data and 4K of bss.

- * FAN ACCESS MODES
- *
- * IBMACPI_FAN_RD_ACPI_GFAN:
- * ACPI GFAN method: returns fan level
- *
- * see IBMACPI_FAN_WR_ACPI_SFAN
- * EC 0x2f not available if GFAN exists
- *
- * IBMACPI_FAN_WR_ACPI_SFAN:
- * ACPI SFAN method: sets fan level, 0 (stop) to 7 (max)
- *
- * EC 0x2f might be available *for reading*, but never for writing.
- *
- * IBMACPI_FAN_WR_TPEC:
- * ThinkPad EC register 0x2f (HFSP): fan control loop mode Supported
- * on almost all ThinkPads
- *
- * Fan speed changes of any sort (including those caused by the
- * disengaged mode) are usually done slowly by the firmware as the
- * maximum ammount of fan duty cycle change per second seems to be
- * limited.
- *
- * Reading is not available if GFAN exists.
- * Writing is not available if SFAN exists.
- *
- * Bits
- * 7 automatic mode engaged;
- * (default operation mode of the ThinkPad)
- * fan level is ignored in this mode.
- * 6 disengage mode (takes precedence over bit 7);
- * not available on all thinkpads. May disable
- * the tachometer, and speeds up fan to 100% duty-cycle,
- * which speeds it up far above the standard RPM
- * levels. It is not impossible that it could cause
- * hardware damage.
- * 5-3 unused in some models. Extra bits for fan level
- * in others, but still useless as all values above
- * 7 map to the same speed as level 7 in these models.
- * 2-0 fan level (0..7 usually)
- * 0x00 = stop
- * 0x07 = max (set when temperatures critical)
- * Some ThinkPads may have other levels, see
- * IBMACPI_FAN_WR_ACPI_FANS (X31/X40/X41)
- *
- * FIRMWARE BUG: on some models, EC 0x2f might not be initialized at
- * boot. Apparently the EC does not intialize it, so unless ACPI DSDT
- * does so, its initial value is meaningless (0x07).
- *
- * For firmware bugs, refer to:
- * http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
- *
- * ----
- *
- * ThinkPad EC register 0x84 (LSB), 0x85 (MSB):
- * Main fan tachometer reading (in RPM)
- *
- * This register is present on all ThinkPads with a new-style EC, and
- * it is known not to be present on the A21m/e, and T22, as there is
- * something else in offset 0x84 according to the ACPI DSDT. Other
- * ThinkPads from this same time period (and earlier) probably lack the
- * tachometer as well.
- *
- * Unfortunately a lot of ThinkPads with new-style ECs but whose firwmare
- * was never fixed by IBM to report the EC firmware version string
- * probably support the tachometer (like the early X models), so
- * detecting it is quite hard. We need more data to know for sure.
- *
- * FIRMWARE BUG: always read 0x84 first, otherwise incorrect readings
- * might result.
- *
- * FIRMWARE BUG: when EC 0x2f bit 6 is set (disengaged mode), this
- * register is not invalidated in ThinkPads that disable tachometer
- * readings. Thus, the tachometer readings go stale.
- *
- * For firmware bugs, refer to:
- * http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
- *
- * IBMACPI_FAN_WR_ACPI_FANS:
- * ThinkPad X31, X40, X41. Not available in the X60.
- *
- * FANS ACPI handle: takes three arguments: low speed, medium speed,
- * high speed. ACPI DSDT seems to map these three speeds to levels
- * as follows: STOP LOW LOW MED MED HIGH HIGH HIGH HIGH
- * (this map is stored on FAN0..FAN8 as "0,1,1,2,2,3,3,3,3")
- *
- * The speeds are stored on handles
- * (FANA:FAN9), (FANC:FANB), (FANE:FAND).
- *
- * There are three default speed sets, acessible as handles:
- * FS1L,FS1M,FS1H; FS2L,FS2M,FS2H; FS3L,FS3M,FS3H
- *
- * ACPI DSDT switches which set is in use depending on various
- * factors.
- *
- * IBMACPI_FAN_WR_TPEC is also available and should be used to
- * command the fan. The X31/X40/X41 seems to have 8 fan levels,
- * but the ACPI tables just mention level 7.

If you say Y here, the kernelcapi driver can make verbose traces
of CAPI messages. This feature can be enabled/disabled via IOCTL for
- every controler (default disabled).
+ every controller (default disabled).
This will increase the size of the kernelcapi module by 20 KB.
If unsure, say Y.

* The basic ADB state machine was left unchanged from the original MacII code

- * The syntax of the ADB status lines seems to be totally different on MacII,
- * though. MacII uses the states Command -> Even -> Odd -> Even ->...-> Idle for
- * sending, and Idle -> Even -> Odd -> Even ->...-> Idle for receiving. Start
- * and end of a receive packet are signaled by asserting /IRQ on the interrupt
- * line. Timeouts are signaled by a sequence of 4 0xFF, with /IRQ asserted on
- * every other byte. SRQ is probably signaled by 3 or more 0xFF tacked on the
- * end of a packet. (Thanks to Guido Koerber for eavesdropping on the ADB
- * protocol with a logic analyzer!!)
- *
- * Note: As of 21/10/97, the MacII ADB part works including timeout detection

+Guess at API of the I2C function:
+I2C operation is done one byte at a time with USB control messages. The
+index the messages is sent to is made up of a set of flags that control
+the I2C bus state:
+0x80: Send START condition. After a START condition, one would normally
+ always send the 7-bit slave I2C address as the 7 MSB, followed by
+ the read/write bit as the LSB.
+0x40: Send STOP condition. This should be set on the last byte of an
+ I2C transaction.
+0x20: Read a byte from the slave. As opposed to writing a byte to the
+ slave. The slave will normally not produce any data unless you
+ set the R/W bit to 1 when sending the slave's address after the
+ START condition.
+0x01: Respond with ACK, as opposed to a NACK. For a multi-byte read,
+ the master should send an ACK, that is pull SDA low during the 9th
+ clock cycle, after every byte but the last. This flags only makes
+ sense when bit 0x20 is set, indicating a read.
+
+What any other bits might mean, or how to get the slave's ACK/NACK
+response to a write, is unknown.

+/*
+ This file includes an i2c implementation that was reverse engineered
+ from the Hauppauge windows driver. Older ivtv versions used i2c-algo-bit,
+ which whilst fine under most circumstances, had trouble with the Zilog
+ CPU on the PVR-150 which handles IR functions (occasional inability to
+ communicate with the chip until it was reset) and also with the i2c
+ bus being completely unreachable when multiple PVR cards were present.
+
+ The implementation is very similar to i2c-algo-bit, but there are enough
+ subtle differences that the two are hard to merge. The general strategy
+ employed by i2c-algo-bit is to use udelay() to implement the timing
+ when putting out bits on the scl/sda lines. The general strategy taken
+ here is to poll the lines for state changes (see ivtv_waitscl and
+ ivtv_waitsda). In addition there are small delays at various locations
+ which poll the SCL line 5 times (ivtv_scldelay). I would guess that
+ since this is memory mapped I/O that the length of those delays is tied
+ to the PCI bus clock. There is some extra code to do with recovery
+ and retries. Since it is not known what causes the actual i2c problems
+ in the first place, the only goal if one was to attempt to use
+ i2c-algo-bit would be to try to make it follow the same code path.
+ This would be a lot of work, and I'm also not convinced that it would
+ provide a generic benefit to i2c-algo-bit. Therefore consider this
+ an engineering solution -- not pretty, but it works.
+
+ Some more general comments about what we are doing:
+
+ The i2c bus is a 2 wire serial bus, with clock (SCL) and data (SDA)
+ lines. To communicate on the bus (as a master, we don't act as a slave),
+ we first initiate a start condition (ivtv_start). We then write the
+ address of the device that we want to communicate with, along with a flag
+ that indicates whether this is a read or a write. The slave then issues
+ an ACK signal (ivtv_ack), which tells us that it is ready for reading /
+ writing. We then proceed with reading or writing (ivtv_read/ivtv_write),
+ and finally issue a stop condition (ivtv_stop) to make the bus available
+ to other masters.
+
+ There is an additional form of transaction where a write may be
+ immediately followed by a read. In this case, there is no intervening
+ stop condition. (Only the msp3400 chip uses this method of data transfer).

+ *
+ * see TPACPI_FAN_WR_ACPI_SFAN
+ * EC 0x2f (HFSP) not available if GFAN exists
+ *
+ * TPACPI_FAN_WR_ACPI_SFAN:
+ * ACPI SFAN method: sets fan level, 0 (stop) to 7 (max)
+ *
+ * EC 0x2f (HFSP) might be available *for reading*, but do not use
+ * it for writing.
+ *
+ * TPACPI_FAN_WR_TPEC:
+ * ThinkPad EC register 0x2f (HFSP): fan control loop mode
+ * Supported on almost all ThinkPads
+ *
+ * Fan speed changes of any sort (including those caused by the
+ * disengaged mode) are usually done slowly by the firmware as the
+ * maximum ammount of fan duty cycle change per second seems to be
+ * limited.
+ *
+ * Reading is not available if GFAN exists.
+ * Writing is not available if SFAN exists.
+ *
+ * Bits
+ * 7 automatic mode engaged;
+ * (default operation mode of the ThinkPad)
+ * fan level is ignored in this mode.
+ * 6 full speed mode (takes precedence over bit 7);
+ * not available on all thinkpads. May disable
+ * the tachometer while the fan controller ramps up
+ * the speed (which can take up to a few *minutes*).
+ * Speeds up fan to 100% duty-cycle, which is far above
+ * the standard RPM levels. It is not impossible that
+ * it could cause hardware damage.
+ * 5-3 unused in some models. Extra bits for fan level
+ * in others, but still useless as all values above
+ * 7 map to the same speed as level 7 in these models.
+ * 2-0 fan level (0..7 usually)
+ * 0x00 = stop
+ * 0x07 = max (set when temperatures critical)
+ * Some ThinkPads may have other levels, see
+ * TPACPI_FAN_WR_ACPI_FANS (X31/X40/X41)
+ *
+ * FIRMWARE BUG: on some models, EC 0x2f might not be initialized at
+ * boot. Apparently the EC does not intialize it, so unless ACPI DSDT
+ * does so, its initial value is meaningless (0x07).
+ *
+ * For firmware bugs, refer to:
+ * http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
+ *
+ * ----
+ *
+ * ThinkPad EC register 0x84 (LSB), 0x85 (MSB):
+ * Main fan tachometer reading (in RPM)
+ *
+ * This register is present on all ThinkPads with a new-style EC, and
+ * it is known not to be present on the A21m/e, and T22, as there is
+ * something else in offset 0x84 according to the ACPI DSDT. Other
+ * ThinkPads from this same time period (and earlier) probably lack the
+ * tachometer as well.
+ *
+ * Unfortunately a lot of ThinkPads with new-style ECs but whose firwmare
+ * was never fixed by IBM to report the EC firmware version string
+ * probably support the tachometer (like the early X models), so
+ * detecting it is quite hard. We need more data to know for sure.
+ *
+ * FIRMWARE BUG: always read 0x84 first, otherwise incorrect readings
+ * might result.
+ *
+ * FIRMWARE BUG: may go stale while the EC is switching to full speed
+ * mode.
+ *
+ * For firmware bugs, refer to:
+ * http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
+ *
+ * TPACPI_FAN_WR_ACPI_FANS:
+ * ThinkPad X31, X40, X41. Not available in the X60.
+ *
+ * FANS ACPI handle: takes three arguments: low speed, medium speed,
+ * high speed. ACPI DSDT seems to map these three speeds to levels
+ * as follows: STOP LOW LOW MED MED HIGH HIGH HIGH HIGH
+ * (this map is stored on FAN0..FAN8 as "0,1,1,2,2,3,3,3,3")
+ *
+ * The speeds are stored on handles
+ * (FANA:FAN9), (FANC:FANB), (FANE:FAND).
+ *
+ * There are three default speed sets, acessible as handles:
+ * FS1L,FS1M,FS1H; FS2L,FS2M,FS2H; FS3L,FS3M,FS3H
+ *
+ * ACPI DSDT switches which set is in use depending on various
+ * factors.
+ *
+ * TPACPI_FAN_WR_TPEC is also available and should be used to
+ * command the fan. The X31/X40/X41 seems to have 8 fan levels,
+ * but the ACPI tables just mention level 7.

+ depends on MTD
+ select CRC32
+ help
+ UBI is a software layer above MTD layer which admits of LVM-like
+ logical volumes on top of MTD devices, hides some complexities of
+ flash chips like wear and bad blocks and provides some other useful
+ capabilities. Please, consult the MTD web site for more details
+ (www.linux-mtd.infradead.org).
+

+ range 2 65536
+ depends on MTD_UBI
+ help
+ This parameter defines the maximum difference between the highest
+ erase counter value and the lowest erase counter value of eraseblocks
+ of UBI devices. When this threshold is exceeded, UBI starts performing
+ wear leveling by means of moving data from eraseblock with low erase
+ counter to eraseblocks with high erase counter. Leave the default
+ value if unsure.
+
+config MTD_UBI_BEB_RESERVE
+ int "Percentage of reserved eraseblocks for bad eraseblocks handling"
+ default 1
+ range 0 25
+ depends on MTD_UBI
+ help
+ If the MTD device admits of bad eraseblocks (e.g. NAND flash), UBI
+ reserves some amount of physical eraseblocks to handle new bad
+ eraseblocks. For example, if a flash physical eraseblock becomes bad,
+ UBI uses these reserved physical eraseblocks to relocate the bad one.
+ This option specifies how many physical eraseblocks will be reserved
+ for bad eraseblock handling (percents of total number of good flash
+ eraseblocks). If the underlying flash does not admit of bad
+ eraseblocks (e.g. NOR flash), this value is ignored and nothing is
+ reserved. Leave the default value if unsure.
+
+config MTD_UBI_GLUEBI
+ bool "Emulate MTD devices"
+ default n
+ depends on MTD_UBI
+ help
+ This option enables MTD devices emulation on top of UBI volumes: for
+ each UBI volumes an MTD device is created, and all I/O to this MTD
+ device is redirected to the UBI volume. This is handy to make
+ MTD-oriented software (like JFFS2) work on top of UBI. Do not enable
+ this if no legacy software will be used.

+/*
+ * UBI input/output unit.
+ *
+ * This unit provides a uniform way to work with all kinds of the underlying
+ * MTD devices. It also implements handy functions for reading and writing UBI
+ * headers.
+ *
+ * We are trying to have a paranoid mindset and not to trust to what we read
+ * from the flash media in order to be more secure and robust. So this unit
+ * validates every single header it reads from the flash media.
+ *
+ * Some words about how the eraseblock headers are stored.
+ *
+ * The erase counter header is always stored at offset zero. By default, the
+ * VID header is stored after the EC header at the closest aligned offset
+ * (i.e. aligned to the minimum I/O unit size). Data starts next to the VID
+ * header at the closest aligned offset. But this default layout may be
+ * changed. For example, for different reasons (e.g., optimization) UBI may be
+ * asked to put the VID header at further offset, and even at an unaligned
+ * offset. Of course, if the offset of the VID header is unaligned, UBI adds
+ * proper padding in front of it. Data offset may also be changed but it has to
+ * be aligned.
+ *
+ * About minimal I/O units. In general, UBI assumes flash device model where
+ * there is only one minimal I/O unit size. E.g., in case of NOR flash it is 1,
+ * in case of NAND flash it is a NAND page, etc. This is reported by MTD in the
+ * @ubi->mtd->writesize field. But as an exception, UBI admits of using another
+ * (smaller) minimal I/O unit size for EC and VID headers to make it possible
+ * to do different optimizations.
+ *
+ * This is extremely useful in case of NAND flashes which admit of several
+ * write operations to one NAND page. In this case UBI can fit EC and VID
+ * headers at one NAND page. Thus, UBI may use "sub-page" size as the minimal
+ * I/O unit for the headers (the @ubi->hdrs_min_io_size field). But it still
+ * reports NAND page size (@ubi->min_io_size) as a minimal I/O unit for the UBI
+ * users.
+ *
+ * Example: some Samsung NANDs with 2KiB pages allow 4x 512-byte writes, so
+ * although the minimal I/O unit is 2K, UBI uses 512 bytes for EC and VID
+ * headers.
+ *
+ * Q: why not just to treat sub-page as a minimal I/O unit of this flash
+ * device, e.g., make @ubi->min_io_size = 512 in the example above?
+ *
+ * A: because when writing a sub-page, MTD still writes a full 2K page but the
+ * bytes which are no relevant to the sub-page are 0xFF. So, basically, writing
+ * 4x512 sub-pages is 4 times slower then writing one 2KiB NAND page. Thus, we
+ * prefer to use sub-pages only for EV and VID headers.
+ *
+ * As it was noted above, the VID header may start at a non-aligned offset.
+ * For example, in case of a 2KiB page NAND flash with a 512 bytes sub-page,
+ * the VID header may reside at offset 1984 which is the last 64 bytes of the
+ * last sub-page (EC header is always at offset zero). This causes some
+ * difficulties when reading and writing VID headers.
+ *
+ * Suppose we have a 64-byte buffer and we read a VID header at it. We change
+ * the data and want to write this VID header out. As we can only write in
+ * 512-byte chunks, we have to allocate one more buffer and copy our VID header
+ * to offset 448 of this buffer.
+ *
+ * The I/O unit does the following trick in order to avoid this extra copy.
+ * It always allocates a @ubi->vid_hdr_alsize bytes buffer for the VID header
+ * and returns a pointer to offset @ubi->vid_hdr_shift of this buffer. When the
+ * VID header is being written out, it shifts the VID header pointer back and
+ * writes the whole sub-page.

+ * eraseblock when the MTD device is attached again.
+ *
+ * The main and obvious use-case of this function is when the contents of a
+ * logical eraseblock has to be re-written. Then it is much more efficient to
+ * first un-map it, then write new data, rather then first erase it, then write
+ * new data. Note, once new data has been written to the logical eraseblock,
+ * UBI guarantees that the old contents has gone forever. In other words, if an
+ * unclean reboot happens after the logical eraseblock has been un-mapped and
+ * then written to, it will contain the last written data.

+ * case of failure. If the volume is damaged because of an interrupted update

+ * This file includes volume table manipulation code. The volume table is an
+ * on-flash table containing volume meta-data like name, number of reserved
+ * physical eraseblocks, type, etc. The volume table is stored in the so-called
+ * "layout volume".
+ *
+ * The layout volume is an internal volume which is organized as follows. It
+ * consists of two logical eraseblocks - LEB 0 and LEB 1. Each logical
+ * eraseblock stores one volume table copy, i.e. LEB 0 and LEB 1 duplicate each
+ * other. This redundancy guarantees robustness to unclean reboots. The volume
+ * table is basically an array of volume table records. Each record contains
+ * full information about the volume and protected by a CRC checksum.
+ *
+ * The volume table is changed, it is first changed in RAM. Then LEB 0 is
+ * erased, and the updated volume table is written back to LEB 0. Then same for
+ * LEB 1. This scheme guarantees recoverability from unclean reboots.
+ *
+ * In this UBI implementation the on-flash volume table does not contain any
+ * information about how many data static volumes contain. This information may
+ * be found from the scanning data.
+ *
+ * But it would still be beneficial to store this information in the volume
+ * table. For example, suppose we have a static volume X, and all its physical
+ * eraseblocks became bad for some reasons. Suppose we are attaching the
+ * corresponding MTD device, the scanning has found no logical eraseblocks
+ * corresponding to the volume X. According to the volume table volume X does
+ * exist. So we don't know whether it is just empty or all its physical
+ * eraseblocks went bad. So we cannot alarm the user about this corruption.
+ *
+ * The volume table also stores so-called "update marker", which is used for
+ * volume updates. Before updating the volume, the update marker is set, and
+ * after the update operation is finished, the update marker is cleared. So if
+ * the update operation was interrupted (e.g. by an unclean reboot) - the
+ * update marker is still there and we know that the volume's contents is

+ * UBI wear-leveling unit.
+ *
+ * This unit is responsible for wear-leveling. It works in terms of physical
+ * eraseblocks and erase counters and knows nothing about logical eraseblocks,
+ * volumes, etc. From this unit's perspective all physical eraseblocks are of
+ * two types - used and free. Used physical eraseblocks are those that were
+ * "get" by the 'ubi_wl_get_peb()' function, and free physical eraseblocks are
+ * those that were put by the 'ubi_wl_put_peb()' function.
+ *
+ * Physical eraseblocks returned by 'ubi_wl_get_peb()' have only erase counter
+ * header. The rest of the physical eraseblock contains only 0xFF bytes.
+ *
+ * When physical eraseblocks are returned to the WL unit by means of the
+ * 'ubi_wl_put_peb()' function, they are scheduled for erasure. The erasure is
+ * done asynchronously in context of the per-UBI device background thread,
+ * which is also managed by the WL unit.
+ *
+ * The wear-leveling is ensured by means of moving the contents of used
+ * physical eraseblocks with low erase counter to free physical eraseblocks
+ * with high erase counter.
+ *
+ * The 'ubi_wl_get_peb()' function accepts data type hints which help to pick
+ * an "optimal" physical eraseblock. For example, when it is known that the
+ * physical eraseblock will be "put" soon because it contains short-term data,
+ * the WL unit may pick a free physical eraseblock with low erase counter, and
+ * so forth.
+ *
+ * If the WL unit fails to erase a physical eraseblock, it marks it as bad.
+ *
+ * This unit is also responsible for scrubbing. If a bit-flip is detected in a
+ * physical eraseblock, it has to be moved. Technically this is the same as
+ * moving it for wear-leveling reasons.
+ *
+ * As it was said, for the UBI unit all physical eraseblocks are either "free"
+ * or "used". Free eraseblock are kept in the @wl->free RB-tree, while used
+ * eraseblocks are kept in a set of different RB-trees: @wl->used,
+ * @wl->prot.pnum, @wl->prot.aec, and @wl->scrub.
+ *
+ * Note, in this implementation, we keep a small in-RAM object for each physical
+ * eraseblock. This is surely not a scalable solution. But it appears to be good
+ * enough for moderately large flashes and it is simple. In future, one may
+ * re-work this unit and make it more scalable.
+ *
+ * At the moment this unit does not utilize the sequence number, which was
+ * introduced relatively recently. But it would be wise to do this because the
+ * sequence number of a logical eraseblock characterizes how old is it. For
+ * example, when we move a PEB with low erase counter, and we need to pick the
+ * target PEB, we pick a PEB with the highest EC if our PEB is "old" and we
+ * pick target PEB with an average EC if our PEB is not very "old". This is a
+ * room for future re-works of the WL unit.
+ *
+ * FIXME: looks too complex, should be simplified (later).

+ * @e: the wear-leveling entry of the physical eraseblock under protection
+ *
+ * When the WL unit returns a physical eraseblock, the physical eraseblock is
+ * protected from being moved for some "time". For this reason, the physical
+ * eraseblock is not directly moved from the @wl->free tree to the @wl->used
+ * tree. There is one more tree in between where this physical eraseblock is
+ * temporarily stored (@wl->prot).
+ *
+ * All this protection stuff is needed because:
+ * o we don't want to move physical eraseblocks just after we have given them
+ * to the user; instead, we first want to let users fill them up with data;
+ *
+ * o there is a chance that the user will put the physical eraseblock very
+ * soon, so it makes sense not to move it for some time, but wait; this is
+ * especially important in case of "short term" physical eraseblocks.
+ *
+ * Physical eraseblocks stay protected only for limited time. But the "time" is
+ * measured in erase cycles in this case. This is implemented with help of the
+ * absolute erase counter (@wl->abs_ec). When it reaches certain value, the
+ * physical eraseblocks are moved from the protection trees (@wl->prot.*) to
+ * the @wl->used tree.
+ *
+ * Protected physical eraseblocks are searched by physical eraseblock number
+ * (when they are put) and by the absolute erase counter (to check if it is
+ * time to move them to the @wl->used tree). So there are actually 2 RB-trees
+ * storing the protected physical eraseblocks: @wl->prot.pnum and
+ * @wl->prot.aec. They are referred to as the "protection" trees. The
+ * first one is indexed by the physical eraseblock number. The second one is
+ * indexed by the absolute erase counter. Both trees store
+ * &struct ubi_wl_prot_entry objects.
+ *
+ * Each physical eraseblock has 2 main states: free and used. The former state
+ * corresponds to the @wl->free tree. The latter state is split up on several
+ * sub-states:
+ * o the WL movement is allowed (@wl->used tree);
+ * o the WL movement is temporarily prohibited (@wl->prot.pnum and
+ * @wl->prot.aec trees);
+ * o scrubbing is needed (@wl->scrub tree).
+ *
+ * Depending on the sub-state, wear-leveling entries of the used physical
+ * eraseblocks may be kept in one of those trees.

+ *
+ * Here the timer peeks at the DP83840 status registers at each click to see

+ * will time out at some point and just tell us what (didn't) happen. For
+ * complete coverage we only allow so many of the ticks at this level to run,
+ * when this has expired we print a warning message and try another strategy.
+ * This "other" strategy is to force the interface into various speed/duplex
+ * configurations and we stop when we see a link-up condition before the
+ * maximum number of "peek" ticks have occurred.
+ *
+ * Once a valid link status has been detected we configure the BigMAC and
+ * the rest of the Happy Meal to speak the most efficient protocol we could
+ * get a clean link for. The priority for link configurations, highest first
+ * is:
+ * 100 Base-T Full Duplex
+ * 100 Base-T Half Duplex
+ * 10 Base-T Full Duplex
+ * 10 Base-T Half Duplex
+ *
+ * We start a new timer now, after a successful auto negotiation status has
+ * been detected. This timer just waits for the link-up bit to get set in
+ * the BMCR of the DP83840. When this occurs we print a kernel log message
+ * describing the link type in use and the fact that it is up.
+ *
+ * If a fatal error of some sort is signalled and detected in the interrupt
+ * service routine, and the chip is reset, or the link is ifconfig'd down

- The beauty of it is that a single set of tool can support all the

- README
- ------
-
- This directory is mostly for Wireless LAN drivers, in their
-various incarnations (ISA, PCI, Pcmcia...).
- This separate directory is needed because a lot of driver work
-on different bus (typically PCI + Pcmcia) and share 95% of the
-code. This allow the code and the config options to be in one single
-place instead of scattered all over the driver tree, which is never
-100% satisfactory.
-
- Note : if you want more info on the topic of Wireless LANs,
-you are kindly invited to have a look at the Wireless Howto :
- http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/
- Some Wireless LAN drivers, like orinoco_cs, require the use of
-Wireless Tools to be configured :
- http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
-
- Special notes for distribution maintainers :
- 1) wvlan_cs will be discontinued soon in favor of orinoco_cs
- 2) Please add Wireless Tools support in your scripts
-
- Have fun...

+BT Commands:
+ The blinding table (BT) contains a list of mac addresses that should be
+ ignored by the firmware. It is primarily used for debugging and
+ testing networks. It can be edited and inspected with the following
+ commands:
+
+ iwpriv ethX bt_reset
+ iwpriv ethX bt_add <mac_address>
+ iwpriv ethX bt_del <mac_address>
+ iwpriv ethX bt_list <id>
+
+FWT Commands:
+ The forwarding table (FWT) is a feature used to manage mesh network
+ routing in the firmware. The FWT is essentially a routing table that
+ associates a destination mac address (da) with a next hop receiver
+ address (ra). The FWT can be inspected and edited with the following
+ iwpriv commands, which are described in greater detail below.
+ Eventually, the table will be automatically maintained by a custom
+ routing protocol.
+
+ NOTE: FWT commands replace the previous DFT commands. What were the DFT
+ commands?, you might ask. They were an earlier API to the firmware that
+ implemented a simple MAC-layer forwarding mechanism. In the unlikely
+ event that you were using these commands, you must migrate to the new
+ FWT commands which can be used to achieve the same functionality.
+
+ iwpriv ethX fwt_add [parameters]
+ iwpriv ethX fwt_del [parameters]
+ iwpriv ethX fwt_lookup [parameters]
+ iwpriv ethX fwt_list [parameters]
+ iwpriv ethX fwt_list_route [parameters]
+ iwpriv ethX fwt_list_neigh [parameters]
+ iwpriv ethX fwt_reset [parameters]
+ iwpriv ethX fwt_cleanup
+ iwpriv ethX fwt_time
+
+MESH Commands:
+
+ The MESH commands are used to configure various features of the mesh
+ routing protocol. The following commands are supported:
+
+ iwpriv ethX mesh_get_ttl
+ iwpriv ethX mesh_set_ttl ttl
+
+DESCRIPTION

+
+getNF
+ This command gets the average and non average value of Noise Floor of
+ Beacon and Data.
+
+ where value is:-
+ 0 -- Beacon non-average.
+ 1 -- Beacon average.
+ 2 -- Data non-average.
+ 3 -- Data average.
+
+ Note: This command is available only when STA is connected.
+
+setrxant
+ This command is used to set the mode for Rx antenna.

+fwt_add
+ This command is used to insert an entry into the FWT table. The list of
+ parameters must follow the following structure:
+
+ iwpriv ethX fwt_add da ra [metric dir ssn dsn hopcount ttl expiration sleepmode snr]
+
+ The parameters between brackets are optional, but they must appear in
+ the order specified. For example, if you want to specify the metric,
+ you must also specify the dir, ssn, and dsn but you need not specify the
+ hopcount, expiration, sleepmode, or snr. Any unspecified parameters
+ will be assigned the defaults specified below.
+
+ The different parameters are:-
+ da -- DA MAC address in the form 00:11:22:33:44:55
+ ra -- RA MAC address in the form 00:11:22:33:44:55
+ metric -- route metric (cost: smaller-metric routes are
+ preferred, default is 0)
+ dir -- direction (1 for direct, 0 for reverse,
+ default is 1)
+ ssn -- Source Sequence Number (time at the RA for
+ reverse routes. Default is 0)
+ dsn -- Destination Sequence Number (time at the DA
+ for direct routes. Default is 0)
+ hopcount -- hop count (currently unused, default is 0)
+ ttl -- TTL (Only used in reverse entries)
+ expiration -- entry expiration (in ticks, where a tick is
+ 1024us, or ~ 1ms. Use 0 for an indefinite
+ entry, default is 0)
+ sleepmode -- RA's sleep mode (currently unused, default is
+ 0)
+ snr -- SNR in the link to RA (currently unused,
+ default is 0)
+
+ The command does not return anything.
+
+fwt_del
+ This command is used to remove an entry to the FWT table. The list of
+ parameters must follow the following structure:
+
+ iwpriv ethX fwt_del da ra [dir]
+
+ where the different parameters are:-
+ da -- DA MAC address (in the form "00:11:22:33:44:55")
+ ra -- RA MAC address (in the form "00:11:22:33:44:55")
+ dir -- direction (1 for direct, 0 for reverse,
+ default is 1)
+
+ The command does not return anything.
+
+fwt_lookup
+ This command is used to get the best route in the FWT table to a given
+ host. The only parameter is the MAC address of the host that is being
+ looked for.
+
+ iwpriv ethX fwt_lookup da
+
+ where:-
+ da -- DA MAC address (in the form "00:11:22:33:44:55")
+
+ The command returns an output string identical to the one returned by
+ fwt_list described below.
+
+
+fwt_list
+ This command is used to list a route from the FWT table. The only
+ parameter is the index into the table. If you want to list all the
+ routes in a table, start with index=0, and keep listing until you get a
+ "(null)" string. Note that the indicies may change as the fwt is
+ updated. It is expected that most users will not use fwt_list directly,
+ but that a utility similar to the traditional route command will be used
+ to invoke fwt_list over and over.
+
+ iwpriv ethX fwt_list index
+
+ The output is a string of the following form:
+
+ da ra metric dir ssn dsn hopcount ttl expiration sleepmode snr
+
+ where the different fields are:-
+ da -- DA MAC address (in the form "00:11:22:33:44:55")
+ ra -- RA MAC address (in the form "00:11:22:33:44:55")
+ metric -- route metric (cost: smaller-metric routes are preferred)
+ dir -- direction (1 for direct, 0 for reverse)
+ ssn -- Source Sequence Number (time at the RA for reverse routes)
+ dsn -- Destination Sequence Number (time at the DA for direct routes)
+ hopcount -- hop count (currently unused)
+ ttl -- TTL (only used in reverse entries)
+ expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
+ sleepmode -- RA's sleep mode (currently unused)
+ snr -- SNR in the link to RA (currently unused)
+
+fwt_list_route
+ This command is used to list a route from the FWT table. The only
+ parameter is the route ID. If you want to list all the routes in a
+ table, start with rid=0, and keep incrementing rid until you get a
+ "(null)" string. This function is similar to fwt_list. The only
+ difference is the output format. Also note that this command is meant
+ for debugging. It is expected that users will use fwt_lookup and
+ fwt_list. One important reason for this is that the route id may change
+ as the route table is altered.
+
+ iwpriv ethX fwt_list_route rid
+
+ The output is a string of the following form:
+
+ da metric dir nid ssn dsn hopcount ttl expiration
+
+ where the different fields are:-
+ da -- DA MAC address (in the form "00:11:22:33:44:55")
+ metric -- route metric (cost: smaller-metric routes are preferred)
+ dir -- direction (1 for direct, 0 for reverse)
+ nid -- Next-hop (neighbor) host ID (nid)
+ ssn -- Source Sequence Number (time at the RA for reverse routes)
+ dsn -- Destination Sequence Number (time at the DA for direct routes)
+ hopcount -- hop count (currently unused)
+ ttl -- TTL count (only used in reverse entries)
+ expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
+
+fwt_list_neigh
+ This command is used to list a neighbor from the FWT table. The only
+ parameter is the neighbor ID. If you want to list all the neighbors in a
+ table, start with nid=0, and keep incrementing nid until you get a
+ "(null)" string. Note that the nid from a fwt_list_route command can be
+ used as an input to this command. Also note that this command is meant
+ mostly for debugging. It is expected that users will use fwt_lookup.
+ One important reason for this is that the neighbor id may change as the
+ neighbor table is altered.
+
+ iwpriv ethX fwt_list_neigh nid
+
+ The output is a string of the following form:
+
+ ra sleepmode snr references
+
+ where the different fields are:-
+ ra -- RA MAC address (in the form "00:11:22:33:44:55")
+ sleepmode -- RA's sleep mode (currently unused)
+ snr -- SNR in the link to RA (currently unused)
+ references -- RA's reference counter
+
+fwt_reset
+ This command is used to reset the FWT table, getting rid of all the
+ entries. There are no input parameters.
+
+ iwpriv ethX fwt_reset
+
+ The command does not return anything.
+
+fwt_cleanup
+ This command is used to perform user-based garbage recollection. The
+ FWT table is checked, and all the entries that are expired or invalid
+ are cleaned. Note that this is exported to the driver for debugging
+ purposes, as garbage collection is also fired by the firmware when in
+ space problems. There are no input parameters.
+
+ iwpriv ethX fwt_cleanup
+
+ The command does returns the number of invalid/expired routes deleted.
+
+fwt_time
+ This command returns a card's internal time representation. It is this
+ time that is used to represent the expiration times of FWT entries. The
+ number is not consistent from card to card; it is simply a timer count.
+ The fwt_time command is used to inspect the timer so that expiration
+ times reported by fwt_list can be properly interpreted.
+
+ iwpriv ethX fwt_time
+
+mesh_get_ttl
+
+ The mesh ttl is the number of hops a mesh packet can traverse before it
+ is dropped. This parameter is used to prevent infinite loops in the
+ mesh network. The value returned by this function is the ttl assigned
+ to all mesh packets. Currently there is no way to control the ttl on a
+ per packet or per socket basis.
+
+ iwpriv ethX mesh_get_ttl
+
+mesh_set_ttl ttl
+
+ Set the ttl. The argument must be between 0 and 255.
+
+ iwpriv ethX mesh_set_ttl <ttl>

+ETHTOOL
+=========================
+
+
+Use the -i option to retrieve version information from the driver.
+
+# ethtool -i eth0
+driver: libertas
+version: COMM-USB8388-318.p4
+firmware-version: 5.110.7
+bus-info:
+
+Use the -e option to read the EEPROM contents of the card.
+
+ Usage:
+ ethtool -e ethX [raw on|off] [offset N] [length N]
+
+ -e retrieves and prints an EEPROM dump for the specified ethernet
+ device. When raw is enabled, then it dumps the raw EEPROM data
+ to stdout. The length and offset parameters allow dumping cer-
+ tain portions of the EEPROM. Default is to dump the entire EEP-
+ ROM.

+DEBUGFS COMMANDS
+========================
+
+those commands are used via debugfs interface
+
+===========
+rdmac
+rdbbp
+rdrf
+ These commands are used to read the MAC, BBP and RF registers from the
+ card. These commands take one parameter that specifies the offset
+ location that is to be read. This parameter must be specified in
+ hexadecimal (its possible to preceed preceding the number with a "0x").
+
+ Path: /debugfs/libertas_wireless/ethX/registers/
+
+ Usage:
+ echo "0xa123" > rdmac ; cat rdmac
+ echo "0xa123" > rdbbp ; cat rdbbp
+ echo "0xa123" > rdrf ; cat rdrf
+wrmac
+wrbbp
+wrrf
+ These commands are used to write the MAC, BBP and RF registers in the
+ card. These commands take two parameters that specify the offset
+ location and the value that is to be written. This parameters must
+ be specified in hexadecimal (its possible to preceed the number
+ with a "0x").
+
+ Usage:
+ echo "0xa123 0xaa" > wrmac
+ echo "0xa123 0xaa" > wrbbp
+ echo "0xa123 0xaa" > wrrf
+
+sleepparams
+ This command is used to set the sleepclock configurations
+
+ Path: /debugfs/libertas_wireless/ethX/
+
+ Usage:
+ cat sleepparams: reads the current sleepclock configuration
+
+ echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration.
+
+ where:
+ p1 is Sleep clock error in ppm (0-65535)
+ p2 is Wakeup offset in usec (0-65535)
+ p3 is Clock stabilization time in usec (0-65535)
+ p4 is Control periodic calibration (0-2)
+ p5 is Control the use of external sleep clock (0-2)
+ p6 is reserved for debug (0-65535)
+
+subscribed_events
+
+ The subscribed_events directory contains the interface for the
+ subscribed events API.
+
+ Path: /debugfs/libertas_wireless/ethX/subscribed_events/
+
+ Each event is represented by a filename. Each filename consists of the
+ following three fields:
+ Value Frequency Subscribed
+
+ To read the current values for a given event, do:
+ cat event
+ To set the current values, do:
+ echo "60 2 1" > event
+
+ Frequency field specifies the reporting frequency for this event.
+ If it is set to 0, then the event is reported only once, and then
+ automatically unsubscribed. If it is set to 1, then the event is
+ reported every time it occurs. If it is set to N, then the event is
+ reported every Nth time it occurs.
+
+ beacon_missed
+ Value field specifies the number of consecutive missing beacons which
+ triggers the LINK_LOSS event. This event is generated only once after
+ which the firmware resets its state. At initialization, the LINK_LOSS
+ event is subscribed by default. The default value of MissedBeacons is
+ 60.
+
+ failure_count
+ Value field specifies the consecutive failure count threshold which
+ triggers the generation of the MAX_FAIL event. Once this event is
+ generated, the consecutive failure count is reset to 0.
+ At initialization, the MAX_FAIL event is NOT subscribed by
+ default.
+
+ high_rssi
+ This event is generated when the average received RSSI in beacons goes
+ above a threshold, specified by Value.
+
+ low_rssi
+ This event is generated when the average received RSSI in beacons goes
+ below a threshold, specified by Value.
+
+ high_snr
+ This event is generated when the average received SNR in beacons goes
+ above a threshold, specified by Value.
+
+ low_snr
+ This event is generated when the average received SNR in beacons goes
+ below a threshold, specified by Value.
+
+extscan
+ This command is used to do a specific scan.
+
+ Path: /debugfs/libertas_wireless/ethX/
+
+ Usage: echo "SSID" > extscan
+
+ Example:
+ echo "LINKSYS-AP" > extscan
+
+ To see the results of use getscantable command.
+
+getscantable
+
+ Display the current contents of the driver scan table (ie. get the
+ scan results).
+
+ Path: /debugfs/libertas_wireless/ethX/
+
+ Usage:
+ cat getscantable
+
+setuserscan
+ Initiate a customized scan and retrieve the results
+
+
+ Path: /debugfs/libertas_wireless/ethX/
+
+ Usage:
+ echo "[ARGS]" > setuserscan
+
+ where [ARGS]:
+
+ chan=[chan#][band][mode] where band is [a,b,g] and mode is
+ blank for active or 'p' for passive
+ bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan
+ ssid="[SSID]" specify a SSID filter for the scan
+ keep=[0 or 1] keep the previous scan results (1), discard (0)
+ dur=[scan time] time to scan for each channel in milliseconds
+ probes=[#] number of probe requests to send on each chan
+ type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any)
+
+ Any combination of the above arguments can be supplied on the command line.
+ If the chan token is absent, a full channel scan will be completed by
+ the driver. If the dur or probes tokens are absent, the driver default
+ setting will be used. The bssid and ssid fields, if blank,
+ will produce an unfiltered scan. The type field will default to 3 (Any)
+ and the keep field will default to 0 (Discard).
+
+ Examples:
+ 1) Perform an active scan on channels 1, 6, and 11 in the 'g' band:
+ echo "chan=1g,6g,11g" > setuserscan
+
+ 2) Perform a passive scan on channel 11 for 20 ms:
+ echo "chan=11gp dur=20" > setuserscan
+
+ 3) Perform an active scan on channels 1, 6, and 11; and a passive scan on
+ channel 36 in the 'a' band:
+
+ echo "chan=1g,6g,11g,36ap" > setuserscan
+
+ 4) Perform an active scan on channel 6 and 36 for a specific SSID:
+ echo "chan=6g,36a ssid="TestAP"" > setuserscan
+
+ 5) Scan all available channels (B/G, A bands) for a specific BSSID, keep
+ the current scan table intact, update existing or append new scan data:
+ echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
+
+ 6) Scan channel 6, for all infrastructure networks, sending two probe
+ requests. Keep the previous scan table intact. Update any duplicate
+ BSSID/SSID matches with the new scan data:
+ echo "chan=6g type=1 probes=2 keep=1" > setuserscan
+
+ All entries in the scan table (not just the new scan data when keep=1)
+ will be displayed upon completion by use of the getscantable ioctl.

- Wireless Todo
- -------------
-
-1) Bring other kernel Wireless LAN drivers here
- Completed
-
-2) Bring new Wireless LAN driver not yet in the kernel there
- See my web page for details
- In particular : HostAP
-
-3) Misc
- o Mark wavelan, wavelan_cs, netwave_cs drivers as obsolete
- o Maybe arlan.c, ray_cs.c and strip.c also deserve to be obsolete
-
- Jean II

- the time from the system clock.
- You want this driver only if you are doing development
- on the RTC subsystem. Please read the source code
- for further details.
-
- This driver can also be built as a module. If so, the module
- will be called rtc-test.

+/* The biggest issue we deal with in this driver is that register writes are
+ * synced to the RTC frequency of 1Hz. So if you write to a register and
+ * attempt to write again before the first write has completed, the new write
+ * is simply discarded. This can easily be troublesome if userspace disables
+ * one event (say periodic) and then right after enables an event (say alarm).
+ * Since all events are maintained in the same interrupt mask register, if
+ * we wrote to it to disable the first event and then wrote to it again to
+ * enable the second event, that second event would not be enabled as the
+ * write would be discarded and things quickly fall apart.
+ *
+ * To keep this delay from significantly degrading performance (we, in theory,
+ * would have to sleep for up to 1 second everytime we wanted to write a
+ * register), we only check the write pending status before we start to issue
+ * a new write. We bank on the idea that it doesnt matter when the sync
+ * happens so long as we don't attempt another write before it does. The only
+ * time userspace would take this penalty is when they try and do multiple
+ * operations right after another ... but in this case, they need to take the
+ * sync penalty, so we should be OK.
+ *
+ * Also note that the RTC_ISTAT register does not suffer this penalty; its
+ * writes to clear status registers complete immediately.

- * This is a representation of the input

- * timing is longer than 400ns depends on this
- * value being correct. For example, you'll
- * get blips for arbitration/selection during
- * high load or with multiple targets if this
- * is not set correctly.
- *
- * b) Selection Time-Out
- *
- * The ESP isn't very bright and will arbitrate
- * for the bus and try to select a target
- * forever if you let it. This value tells
- * the ESP when it has taken too long to
- * negotiate and that it should interrupt
- * the CPU so we can see what happened.
- * The value is computed as follows (from
- * NCR/Symbios chip docs).
- *
- * (Time Out Period) * (Input Clock)
- * STO = ----------------------------------
- * (8192) * (Clock Conversion Factor)
- *
- * You usually want the time out period to be
- * around 250ms, I think we'll set it a little
- * bit higher to account for fully loaded SCSI
- * bus's and slow devices that don't respond so
- * quickly to selection attempts. (yeah, I know
- * this is out of spec. but there is a lot of
- * buggy pieces of firmware out there so bite me)
- *
- * c) Imperical constants for synchronous offset
- * and transfer period register values
- *
- * This entails the smallest and largest sync
- * period we could ever handle on this ESP.

- to guarantee that control traffic gets 10% of the bandwidth, and periodic transfer may
- allocate the rest (90%). This doesn't work though. Read on for a lenghty explanation.
-
- While there is a difference between rev. 2 and rev. 3 of the ETRAX 100LX regarding the NAK
- behaviour, it doesn't solve this problem. What happens is that a control transfer will not
- be interrupted in its data stage when PSTART happens (the point at which periodic traffic
- is started). Thus, if PSTART is set to 10800 and its IN or OUT token is NAKed until just before
- PSTART happens, it will continue the IN/OUT transfer as long as it's ACKed. After it's done,
- there may be too little time left for an isochronous transfer, causing an epid attention
- interrupt due to perror. The work-around for this is to let the control transfers run at the
- end of the frame instead of at the beginning, and will be interrupted just fine if it doesn't
- fit into the frame. However, since there will *always* be a control transfer at the beginning
- of the frame, regardless of what we set PSTART to, that transfer might be a 64-byte transfer
- which consumes up to 15% of the frame, leaving only 85% for periodic traffic. The solution to
- this would be to 'dummy allocate' 5% of the frame with the usb_claim_bandwidth function to make
- sure that the periodic transfers that are inserted will always fit in the frame.
-
- The idea was suggested that a control transfer could be split up into several 8 byte transfers,
- so that it would be interrupted by PSTART, but since this can't be done for an IN transfer this
- hasn't been implemented.
-
- The value 11960 is chosen to be just after the SOF token, with a couple of bit times extra
- for possible bit stuffing. */

- *
- * Kudos to ITM for providing me with the datasheet for the panel,
- * even though it was a day later than I had finished writing this
- * driver.
- *
- * It has meant that I've been able to correct my interpretation of the
- * protocol packets however.
- *
- * CC -- 2003/9/29
- *
- * History
- * 1.0 & 1.1 2003 (CC) vojtech@suse.cz
- * Original version for 2.4.x kernels
- *
- * 1.2 02/03/2005 (HCE) hc@mivu.no
- * Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
- * Unfortunately no calibration support at this time.
- *
- * 1.2.1 09/03/2005 (HCE) hc@mivu.no
- * Code cleanup and adjusting syntax to start matching kernel standards
- *
- * 1.2.2 10/05/2006 (MJA) massad@gmail.com
- * Flag for detecting if the screen was being touch was incorrectly
- * inverted, so no touch events were being detected.

+ *
+ * Code is very simple, just gruesome expansion. Basic strategy is to
+ * increase data moved/cleared at each step to 16 bytes to reduce
+ * instruction per data move overhead. movem might be faster still
+ * For more than 15 bytes, we try to align the write direction on a

+ * linux/drivers/video/hecubafb.c -- FB driver for Hecuba controller
+ *
+ * Copyright (C) 2006, Jaya Kumar
+ * This work was sponsored by CIS(M) Sdn Bhd
+ *
+ * This file is subject to the terms and conditions of the GNU General Public
+ * License. See the file COPYING in the main directory of this archive for
+ * more details.
+ *
+ * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
+ * This work was possible because of apollo display code from E-Ink's website
+ * http://support.eink.com/community
+ * All information used to write this code is from public material made
+ * available by E-Ink on its support site. Some commands such as 0xA4
+ * were found by looping through cmd=0x00 thru 0xFF and supplying random
+ * values. There are other commands that the display is capable of,
+ * beyond the 5 used here but they are more complex.
+ *
+ * This driver is written to be used with the Hecuba display controller
+ * board, and tested with the EInk 800x600 display in 1 bit mode.
+ * The interface between Hecuba and the host is TTL based GPIO. The
+ * GPIO requirements are 8 writable data lines and 6 lines for control.
+ * Only 4 of the controls are actually used here but 6 for future use.
+ * The driver requires the IO addresses for data and control GPIO at
+ * load time. It is also possible to use this display with a standard
+ * PC parallel port.
+ *
+ * General notes:
+ * - User must set hecubafb_enable=1 to enable it
+ * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR

- *
- * This is the "low-level" comms layer.
- *
- * It is responsible for sending/receiving messages
- * from other nodes in the cluster.
- *
- * Cluster nodes are referred to by their nodeids. nodeids are
- * simply 32 bit numbers to the locking module - if they need to
- * be expanded for the cluster infrastructure then that is it's
- * responsibility. It is this layer's
- * responsibility to resolve these into IP address or
- * whatever it needs for inter-node communication.
- *
- * The comms level is two kernel threads that deal mainly with
- * the receiving of messages from other nodes and passing them
- * up to the mid-level comms layer (which understands the

- * IO port access primitives
- * -------------------------
- *
- * The AVR32 doesn't have special IO access instructions; all IO is memory
- * mapped. Note that these are defined to perform little endian accesses
- * only. Their primary purpose is to access PCI and ISA peripherals.
- *
- * Note that for a big endian machine, this implies that the following
- * big endian mode connectivity is in place.
- *
- * The machine specific io.h include defines __io to translate an "IO"
- * address to a memory address.
- *
- * Note that we prevent GCC re-ordering or caching values in expressions
- * by introducing sequence points into the in*() definitions. Note that
- * __raw_* do not guarantee this behaviour.
- *
- * The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.

+ * On the Blackfin, the interrupt structure allows remmapping of the hardware
+ * levels.
+ * - I'm going to assume that the H/W level is going to stay at the default
+ * settings. If someone wants to go through and abstart this out, feel free
+ * to mod the interrupt numbering scheme.
+ * - I'm abstracting the interrupts so that uClinux does not know anything
+ * about the H/W levels. If you want to change the H/W AND keep the abstracted
+ * levels that uClinux sees, you should be able to do most of it here.
+ * - I've left the "abstract" numbering sparce in case someone wants to pull the
+ * interrupts apart (just the TX/RX for the various devices)

+/* Core file format: The core file is written in such a way that gdb
+ can understand it and provide useful information to the user (under
+ linux we use the 'trad-core' bfd). There are quite a number of
+ obstacles to being able to view the contents of the floating point
+ registers, and until these are solved you will not be able to view the
+ contents of them. Actually, you can read in the core file and look at
+ the contents of the user struct to find out what the floating point
+ registers contain.
+ The actual file contents are as follows:
+ UPAGE: 1 page consisting of a user struct that tells gdb what is present
+ in the file. Directly after this is a copy of the task_struct, which
+ is currently not used by gdb, but it may come in useful at some point.
+ All of the registers are stored as part of the upage. The upage should
+ always be only one page.
+ DATA: The data area is stored. We use current->end_text to
+ current->brk to pick up all of the user variables, plus any memory
+ that may have been malloced. No attempt is made to determine if a page
+ is demand-zero or if a page is totally unused, we just cover the entire
+ range. All of the addresses are rounded in such a way that an integral
+ number of pages is written.
+ STACK: We need the stack information in order to get a meaningful
+ backtrace. We need to write the data from (esp) to
+ current->start_stack, so we round each of these off in order to be able
+ to write an integer number of pages.
+ The minimum core file size is 3 pages, or 12288 bytes.

+ * These macros are intended to wrap calls into a paravirt_ops
+ * operation, so that they can be later identified and patched at
+ * runtime.
+ *
+ * Normally, a call to a pv_op function is a simple indirect call:
+ * (paravirt_ops.operations)(args...).
+ *
+ * Unfortunately, this is a relatively slow operation for modern CPUs,
+ * because it cannot necessarily determine what the destination
+ * address is. In this case, the address is a runtime constant, so at
+ * the very least we can patch the call to e a simple direct call, or
+ * ideally, patch an inline implementation into the callsite. (Direct
+ * calls are essentially free, because the call and return addresses
+ * are completely predictable.)
+ *
+ * These macros rely on the standard gcc "regparm(3)" calling
+ * convention, in which the first three arguments are placed in %eax,
+ * %edx, %ecx (in that order), and the remaining arguments are placed
+ * on the stack. All caller-save registers (eax,edx,ecx) are expected
+ * to be modified (either clobbered or used for return values).
+ *
+ * The call instruction itself is marked by placing its start address
+ * and size into the .parainstructions section, so that
+ * apply_paravirt() in arch/i386/kernel/alternative.c can do the
+ * appropriate patching under the control of the backend paravirt_ops
+ * implementation.
+ *
+ * Unfortunately there's no way to get gcc to generate the args setup
+ * for the call, and then allow the call itself to be generated by an
+ * inline asm. Because of this, we must do the complete arg setup and
+ * return value handling from within these macros. This is fairly
+ * cumbersome.
+ *
+ * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments.
+ * It could be extended to more arguments, but there would be little
+ * to be gained from that. For each number of arguments, there are
+ * the two VCALL and CALL variants for void and non-void functions.
+ *
+ * When there is a return value, the invoker of the macro must specify
+ * the return type. The macro then uses sizeof() on that type to
+ * determine whether its a 32 or 64 bit value, and places the return
+ * in the right register(s) (just %eax for 32-bit, and %edx:%eax for
+ * 64-bit).
+ *
+ * 64-bit arguments are passed as a pair of adjacent 32-bit arguments
+ * in low,high order.
+ *
+ * Small structures are passed and returned in registers. The macro
+ * calling convention can't directly deal with this, so the wrapper
+ * functions must do this.
+ *
+ * These PVOP_* macros are only defined within this header. This
+ * means that all uses must be wrapped in inline functions. This also
+ * makes sure the incoming and outgoing types are always correct.

+ * (context << 15) | (esid & 0x7fff)
+ *
+ * The two forms are distinguishable because the top bit is 0 for user
+ * addresses, whereas the top two bits are 1 for kernel addresses.
+ * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
+ * now.
+ *
+ * The proto-VSIDs are then scrambled into real VSIDs with the
+ * multiplicative hash:
+ *
+ * VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
+ * where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
+ * VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
+ *
+ * This scramble is only well defined for proto-VSIDs below
+ * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
+ * reserved. VSID_MULTIPLIER is prime, so in particular it is
+ * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
+ * Because the modulus is 2^n-1 we can compute it efficiently without
+ * a divide or extra multiply (see below).
+ *
+ * This scheme has several advantages over older methods:
+ *
+ * - We have VSIDs allocated for every kernel address
+ * (i.e. everything above 0xC000000000000000), except the very top
+ * segment, which simplifies several things.
+ *
+ * - We allow for 15 significant bits of ESID and 20 bits of
+ * context for user addresses. i.e. 8T (43 bits) of address space for
+ * up to 1M contexts (although the page table structure and context
+ * allocation will need changes to take advantage of this).
+ *
+ * - The scramble function gives robust scattering in the hash
+ * table (at least based on some initial results). The previous
+ * method was more susceptible to pathological cases giving excessive
+ * hash collisions.

- * VSID allocation
- *
- * We first generate a 36-bit "proto-VSID". For kernel addresses this
- * is equal to the ESID, for user addresses it is:
- * (context << 15) | (esid & 0x7fff)
- *
- * The two forms are distinguishable because the top bit is 0 for user
- * addresses, whereas the top two bits are 1 for kernel addresses.
- * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
- * now.
- *
- * The proto-VSIDs are then scrambled into real VSIDs with the
- * multiplicative hash:
- *
- * VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
- * where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
- * VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
- *
- * This scramble is only well defined for proto-VSIDs below
- * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
- * reserved. VSID_MULTIPLIER is prime, so in particular it is
- * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
- * Because the modulus is 2^n-1 we can compute it efficiently without
- * a divide or extra multiply (see below).
- *
- * This scheme has several advantages over older methods:
- *
- * - We have VSIDs allocated for every kernel address
- * (i.e. everything above 0xC000000000000000), except the very top
- * segment, which simplifies several things.
- *
- * - We allow for 15 significant bits of ESID and 20 bits of
- * context for user addresses. i.e. 8T (43 bits) of address space for
- * up to 1M contexts (although the page table structure and context
- * allocation will need changes to take advantage of this).
- *
- * - The scramble function gives robust scattering in the hash
- * table (at least based on some initial results). The previous
- * method was more susceptible to pathological cases giving excessive
- * hash collisions.

+ * needed for the TLB and tablewalk. These definitions require Mx_CTR.PPM = 0,
+ * Mx_CTR.PPCS = 0, and MD_CTR.TWAM = 1. The level 2 descriptor has
+ * additional page protection (when Mx_CTR.PPCS = 1) that allows TLB hit
+ * based upon user/super access. The TLB does not have accessed nor write
+ * protect. We assume that if the TLB get loaded with an entry it is
+ * accessed, and overload the changed bit for write protect. We use
+ * two bits in the software pte that are supposed to be set to zero in
+ * the TLB entry (24 and 25) for these indicators. Although the level 1
+ * descriptor contains the guarded and writethrough/copyback bits, we can
+ * set these at the page level since they get copied from the Mx_TWC
+ * register when the TLB entry is loaded. We will use bit 27 for guard, since
+ * that is where it exists in the MD_TWC, and bit 26 for writethrough.
+ * These will get masked from the level 2 descriptor at TLB load time, and
+ * copied to the MD_TWC before it gets loaded.
+ * Large page sizes added. We currently support two sizes, 4K and 8M.
+ * This also allows a TLB hander optimization because we can directly
+ * load the PMD into MD_TWC. The 8M pages are only used for kernel
+ * mapping of well known areas. The PMD (PGD) entries contain control
+ * flags in addition to the address, so care must be taken that the

+ * @used_bytes: how many bytes of data this volume contains
+ * @used_ebs: how many physical eraseblocks of this volume actually contain any
+ * data
+ * @vol_type: volume type (%UBI_DYNAMIC_VOLUME or %UBI_STATIC_VOLUME)
+ * @corrupted: non-zero if the volume is corrupted (static volumes only)
+ * @upd_marker: non-zero if the volume has update marker set
+ * @alignment: volume alignment
+ * @usable_leb_size: how many bytes are available in logical eraseblocks of
+ * this volume
+ * @name_len: volume name length
+ * @name: volume name
+ * @cdev: UBI volume character device major and minor numbers
+ *
+ * The @corrupted flag is only relevant to static volumes and is always zero
+ * for dynamic ones. This is because UBI does not care about dynamic volume
+ * data protection and only cares about protecting static volume data.
+ *
+ * The @upd_marker flag is set if the volume update operation was interrupted.
+ * Before touching the volume data during the update operation, UBI first sets
+ * the update marker flag for this volume. If the volume update operation was
+ * further interrupted, the update marker indicates this. If the update marker
+ * is set, the contents of the volume is certainly damaged and a new volume
+ * update operation has to be started.
+ *
+ * To put it differently, @corrupted and @upd_marker fields have different
+ * semantics:
+ * o the @corrupted flag means that this static volume is corrupted for some
+ * reasons, but not because an interrupted volume update
+ * o the @upd_marker field means that the volume is damaged because of an
+ * interrupted update operation.
+ *
+ * I.e., the @corrupted flag is never set if the @upd_marker flag is set.
+ *
+ * The @used_bytes and @used_ebs fields are only really needed for static
+ * volumes and contain the number of bytes stored in this static volume and how
+ * many eraseblock this data occupies. In case of dynamic volumes, the
+ * @used_bytes field is equivalent to @size*@usable_leb_size, and the @used_ebs
+ * field is equivalent to @size.
+ *
+ * In general, logical eraseblock size is a property of the UBI device, not
+ * of the UBI volume. Indeed, the logical eraseblock size depends on the
+ * physical eraseblock size and on how much bytes UBI headers consume. But
+ * because of the volume alignment (@alignment), the usable size of logical
+ * eraseblocks if a volume may be less. The following equation is true:
+ * @usable_leb_size = LEB size - (LEB size mod @alignment),
+ * where LEB size is the logical eraseblock size defined by the UBI device.
+ *
+ * The alignment is multiple to the minimal flash input/output unit size or %1
+ * if all the available space is used.
+ *
+ * To put this differently, alignment may be considered is a way to change
+ * volume logical eraseblock sizes.

+ * In POSIX a signal is sent either to a specific thread (Linux task)
+ * or to the process as a whole (Linux thread group). How the signal
+ * is sent determines whether it's to one thread or the whole group,
+ * which determines which signal mask(s) are involved in blocking it
+ * from being delivered until later. When the signal is delivered,
+ * either it's caught or ignored by a user handler or it has a default
+ * effect that applies to the whole thread group (POSIX process).
+ *
+ * The possible effects an unblocked signal set to SIG_DFL can have are:
+ * ignore - Nothing Happens
+ * terminate - kill the process, i.e. all threads in the group,
+ * similar to exit_group. The group leader (only) reports
+ * WIFSIGNALED status to its parent.
+ * coredump - write a core dump file describing all threads using
+ * the same mm and then kill all those threads
+ * stop - stop all the threads in the group, i.e. TASK_STOPPED state
+ *
+ * SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
+ * Other signals when not blocked and set to SIG_DFL behaves as follows.
+ * The job control signals also have other special effects.

+ * @padding1: reserved for future, zeroes
+ * @sqnum: sequence number
+ * @padding2: reserved for future, zeroes
+ * @hdr_crc: volume identifier header CRC checksum
+ *
+ * The @sqnum is the value of the global sequence counter at the time when this
+ * VID header was created. The global sequence counter is incremented each time
+ * UBI writes a new VID header to the flash, i.e. when it maps a logical
+ * eraseblock to a new physical eraseblock. The global sequence counter is an
+ * unsigned 64-bit integer and we assume it never overflows. The @sqnum
+ * (sequence number) is used to distinguish between older and newer versions of
+ * logical eraseblocks.
+ *
+ * There are 2 situations when there may be more then one physical eraseblock
+ * corresponding to the same logical eraseblock, i.e., having the same @vol_id
+ * and @lnum values in the volume identifier header. Suppose we have a logical
+ * eraseblock L and it is mapped to the physical eraseblock P.
+ *
+ * 1. Because UBI may erase physical eraseblocks asynchronously, the following
+ * situation is possible: L is asynchronously erased, so P is scheduled for
+ * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
+ * so P1 is written to, then an unclean reboot happens. Result - there are 2
+ * physical eraseblocks P and P1 corresponding to the same logical eraseblock
+ * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
+ * flash.
+ *
+ * 2. From time to time UBI moves logical eraseblocks to other physical
+ * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
+ * to P1, and an unclean reboot happens before P is physically erased, there
+ * are two physical eraseblocks P and P1 corresponding to L and UBI has to
+ * select one of them when the flash is attached. The @sqnum field says which
+ * PEB is the original (obviously P will have lower @sqnum) and the copy. But
+ * it is not enough to select the physical eraseblock with the higher sequence
+ * number, because the unclean reboot could have happen in the middle of the
+ * copying process, so the data in P is corrupted. It is also not enough to
+ * just select the physical eraseblock with lower sequence number, because the
+ * data there may be old (consider a case if more data was added to P1 after
+ * the copying). Moreover, the unclean reboot may happen when the erasure of P
+ * was just started, so it result in unstable P, which is "mostly" OK, but
+ * still has unstable bits.
+ *
+ * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
+ * copy. UBI also calculates data CRC when the data is moved and stores it at
+ * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
+ * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
+ * examined. If it is cleared, the situation* is simple and the newer one is
+ * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
+ * checksum is correct, this physical eraseblock is selected (P1). Otherwise
+ * the older one (P) is selected.
+ *
+ * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
+ * in the past. But it is not used anymore and we keep it in order to be able
+ * to deal with old UBI images. It will be removed at some point.
+ *
+ * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
+ * Internal volumes are not seen from outside and are used for various internal
+ * UBI purposes. In this implementation there is only one internal volume - the
+ * layout volume. Internal volumes are the main mechanism of UBI extensions.
+ * For example, in future one may introduce a journal internal volume. Internal
+ * volumes have their own reserved range of IDs.
+ *
+ * The @compat field is only used for internal volumes and contains the "degree
+ * of their compatibility". It is always zero for user volumes. This field
+ * provides a mechanism to introduce UBI extensions and to be still compatible
+ * with older UBI binaries. For example, if someone introduced a journal in
+ * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
+ * journal volume. And in this case, older UBI binaries, which know nothing
+ * about the journal volume, would just delete this volume and work perfectly
+ * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
+ * - it just ignores the Ext3fs journal.
+ *
+ * The @data_crc field contains the CRC checksum of the contents of the logical
+ * eraseblock if this is a static volume. In case of dynamic volumes, it does
+ * not contain the CRC checksum as a rule. The only exception is when the
+ * data of the physical eraseblock was moved by the wear-leveling unit, then
+ * the wear-leveling unit calculates the data CRC and stores it in the
+ * @data_crc field. And of course, the @copy_flag is %in this case.
+ *
+ * The @data_size field is used only for static volumes because UBI has to know
+ * how many bytes of data are stored in this eraseblock. For dynamic volumes,
+ * this field usually contains zero. The only exception is when the data of the
+ * physical eraseblock was moved to another physical eraseblock for
+ * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
+ * contents and uses both @data_crc and @data_size fields. In this case, the
+ * @data_size field contains data size.
+ *
+ * The @used_ebs field is used only for static volumes and indicates how many
+ * eraseblocks the data of the volume takes. For dynamic volumes this field is
+ * not used and always contains zero.
+ *
+ * The @data_pad is calculated when volumes are created using the alignment
+ * parameter. So, effectively, the @data_pad field reduces the size of logical
+ * eraseblocks of this volume. This is very handy when one uses block-oriented
+ * software (say, cramfs) on top of the UBI volume.

+ *
+ * The @upd_marker flag is used to implement volume update. It is set to %1

+ *
+ * Volume update should be done via the %UBI_IOCVOLUP IOCTL command of the

+ * size should be passed to the IOCTL. After then, UBI expects user to write
+ * this number of bytes to the volume character device. The update is finished

+ * is something like:
+ *
+ * fd = open("/dev/my_volume");

+ * write(fd, buf, image_size);

- * In POSIX a signal is sent either to a specific thread (Linux task)
- * or to the process as a whole (Linux thread group). How the signal
- * is sent determines whether it's to one thread or the whole group,
- * which determines which signal mask(s) are involved in blocking it
- * from being delivered until later. When the signal is delivered,
- * either it's caught or ignored by a user handler or it has a default
- * effect that applies to the whole thread group (POSIX process).
- *
- * The possible effects an unblocked signal set to SIG_DFL can have are:
- * ignore - Nothing Happens
- * terminate - kill the process, i.e. all threads in the group,
- * similar to exit_group. The group leader (only) reports
- * WIFSIGNALED status to its parent.
- * coredump - write a core dump file describing all threads using
- * the same mm and then kill all those threads
- * stop - stop all the threads in the group, i.e. TASK_STOPPED state
- *
- * SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
- * Other signals when not blocked and set to SIG_DFL behaves as follows.
- * The job control signals also have other special effects.
- *
- * +--------------------+------------------+
- * | POSIX signal | default action |
- * +--------------------+------------------+
- * | SIGHUP | terminate |
- * | SIGINT | terminate |
- * | SIGQUIT | coredump |
- * | SIGILL | coredump |
- * | SIGTRAP | coredump |
- * | SIGABRT/SIGIOT | coredump |
- * | SIGBUS | coredump |
- * | SIGFPE | coredump |
- * | SIGKILL | terminate(+) |
- * | SIGUSR1 | terminate |
- * | SIGSEGV | coredump |
- * | SIGUSR2 | terminate |
- * | SIGPIPE | terminate |
- * | SIGALRM | terminate |
- * | SIGTERM | terminate |
- * | SIGCHLD | ignore |
- * | SIGCONT | ignore(*) |
- * | SIGSTOP | stop(*)(+) |
- * | SIGTSTP | stop(*) |
- * | SIGTTIN | stop(*) |
- * | SIGTTOU | stop(*) |
- * | SIGURG | ignore |
- * | SIGXCPU | coredump |
- * | SIGXFSZ | coredump |
- * | SIGVTALRM | terminate |
- * | SIGPROF | terminate |
- * | SIGPOLL/SIGIO | terminate |
- * | SIGSYS/SIGUNUSED | coredump |
- * | SIGSTKFLT | terminate |
- * | SIGWINCH | ignore |
- * | SIGPWR | terminate |
- * | SIGRTMIN-SIGRTMAX | terminate |
- * +--------------------+------------------+
- * | non-POSIX signal | default action |
- * +--------------------+------------------+
- * | SIGEMT | coredump |
- * +--------------------+------------------+
- *
- * (+) For SIGKILL and SIGSTOP the action is "always", not just "default".
- * (*) Special job control effects:
- * When SIGCONT is sent, it resumes the process (all threads in the group)
- * from TASK_STOPPED state and also clears any pending/queued stop signals
- * (any of those marked with "stop(*)"). This happens regardless of blocking,
- * catching, or ignoring SIGCONT. When any stop signal is sent, it clears
- * any pending/queued SIGCONT signals; this happens regardless of blocking,
- * catching, or ignored the stop signal, though (except for SIGSTOP) the
- * default action of stopping the process may happen later or never.

+ * Lock order:
+ * 1. slab_lock(page)
+ * 2. slab->list_lock
+ *
+ * The slab_lock protects operations on the object of a particular
+ * slab and its metadata in the page struct. If the slab lock
+ * has been taken then no allocations nor frees can be performed
+ * on the objects in the slab nor can the slab be added or removed
+ * from the partial or full lists since this would mean modifying
+ * the page_struct of the slab.
+ *
+ * The list_lock protects the partial and full list on each node and
+ * the partial slab counter. If taken then no new slabs may be added or
+ * removed from the lists nor make the number of partial slabs be modified.
+ * (Note that the total number of slabs is an atomic value that may be
+ * modified without taking the list lock).
+ *
+ * The list_lock is a centralized lock and thus we avoid taking it as
+ * much as possible. As long as SLUB does not have to handle partial
+ * slabs, operations can continue without any centralized lock. F.e.
+ * allocating a long series of objects that fill up slabs does not require
+ * the list lock.
+ *
+ * The lock order is sometimes inverted when we are trying to get a slab
+ * off a list. We take the list_lock and then look for a page on the list
+ * to use. While we do that objects in the slabs may be freed. We can
+ * only operate on the slab if we have also taken the slab_lock. So we use
+ * a slab_trylock() on the slab. If trylock was successful then no frees
+ * can occur anymore and we can use the slab for allocations etc. If the
+ * slab_trylock() does not succeed then frees are in progress in the slab and
+ * we must stay away from it for a while since we may cause a bouncing
+ * cacheline if we try to acquire the lock. So go onto the next slab.
+ * If all pages are busy then we may allocate a new slab instead of reusing
+ * a partial slab. A new slab has noone operating on it and thus there is
+ * no danger of cacheline contention.
+ *
+ * Interrupts are disabled during allocation and deallocation in order to
+ * make the slab allocator safe to use in the context of an irq. In addition
+ * interrupts are disabled to ensure that the processor does not change
+ * while handling per_cpu slabs, due to kernel preemption.
+ *
+ * SLUB assigns one slab for allocation to each processor.
+ * Allocations only occur from these slabs called cpu slabs.
+ *
+ * Slabs with free elements are kept on a partial list and during regular
+ * operations no list for full slabs is used. If an object in a full slab is
+ * freed then the slab will show up again on the partial lists.
+ * We track full slabs for debugging purposes though because otherwise we
+ * cannot scan all objects.
+ *
+ * Slabs are freed when they become empty. Teardown and setup is
+ * minimal so we rely on the page allocators per cpu caches for
+ * fast frees and allocs.
+ *
+ * Overloading of page flags that are otherwise used for LRU management.
+ *
+ * PageActive The slab is used as a cpu cache. Allocations
+ * may be performed from the slab. The slab is not
+ * on any slab list and cannot be moved onto one.
+ *
+ * PageError Slab requires special handling due to debug
+ * options set. This moves slab handling out of
+ * the fast path.

This option adds a `SAME' target, which works like the standard SNAT
target, but attempts to give clients the same IP for all connections.

- This module implements an Application Layer Gateway (ALG) for

- * ip_conntrack_pptp.c - Version 3.0
- *
- * Connection tracking support for PPTP (Point to Point Tunneling Protocol).
- * PPTP is a a protocol for creating virtual private networks.
- * It is a specification defined by Microsoft and some vendors
- * working with Microsoft. PPTP is built on top of a modified
- * version of the Internet Generic Routing Encapsulation Protocol.
- * GRE is defined in RFC 1701 and RFC 1702. Documentation of
- * PPTP can be found in RFC 2637
- *
- * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
- *
- * Development of this code funded by Astaro AG (http://www.astaro.com/)
- *
- * Limitations:
- * - We blindly assume that control connections are always
- * established in PNS->PAC direction. This is a violation
- * of RFFC2673
- * - We can only support one single call within each session
- *
- * TODO:
- * - testing of incoming PPTP calls
- *
- * Changes:
- * 2002-02-05 - Version 1.3
- * - Call ip_conntrack_unexpect_related() from
- * pptp_destroy_siblings() to destroy expectations in case
- * CALL_DISCONNECT_NOTIFY or tcp fin packet was seen
- * (Philip Craig <philipc@snapgear.com>)
- * - Add Version information at module loadtime
- * 2002-02-10 - Version 1.6
- * - move to C99 style initializers
- * - remove second expectation if first arrives
- * 2004-10-22 - Version 2.0
- * - merge Mandrake's 2.6.x port with recent 2.6.x API changes
- * - fix lots of linear skb assumptions from Mandrake's port
- * 2005-06-10 - Version 2.1
- * - use ip_conntrack_expect_free() instead of kfree() on the
- * expect's (which are from the slab for quite some time)
- * 2005-06-10 - Version 3.0
- * - port helper to post-2.6.11 API changes,
- * funded by Oxcoda NetBox Blue (http://www.netboxblue.com/)
- * 2005-07-30 - Version 3.1
- * - port helper to 2.6.13 API changes
- *

- *
- * It has an optional key field, which may help us distinguishing two
- * connections between the same two hosts.
- *
- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
- *
- * PPTP is built on top of a modified version of GRE, and has a mandatory

-NONE - Nothing so far.
-COOKIE WAIT - We have seen an INIT chunk in the original direction, or also
- an INIT_ACK chunk in the reply direction.
-COOKIE ECHOED - We have seen a COOKIE_ECHO chunk in the original direction.
-ESTABLISHED - We have seen a COOKIE_ACK in the reply direction.
-SHUTDOWN_SENT - We have seen a SHUTDOWN chunk in the original direction.
-SHUTDOWN_RECD - We have seen a SHUTDOWN chunk in the reply directoin.
-SHUTDOWN_ACK_SENT - We have seen a SHUTDOWN_ACK chunk in the direction opposite
- to that of the SHUTDOWN chunk.
-CLOSED - We have seen a SHUTDOWN_COMPLETE chunk in the direction of
- the SHUTDOWN chunk. Connection is closed.

- * ip_nat_pptp.c - Version 3.0
- *
- * NAT support for PPTP (Point to Point Tunneling Protocol).
- * PPTP is a a protocol for creating virtual private networks.
- * It is a specification defined by Microsoft and some vendors
- * working with Microsoft. PPTP is built on top of a modified
- * version of the Internet Generic Routing Encapsulation Protocol.
- * GRE is defined in RFC 1701 and RFC 1702. Documentation of
- * PPTP can be found in RFC 2637
- *
- * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
- *
- * Development of this code funded by Astaro AG (http://www.astaro.com/)
- *
- * TODO: - NAT to a unique tuple, not to TCP source port
- * (needs netfilter tuple reservation)
- *
- * Changes:
- * 2002-02-10 - Version 1.3
- * - Use ip_nat_mangle_tcp_packet() because of cloned skb's
- * in local connections (Philip Craig <philipc@snapgear.com>)
- * - add checks for magicCookie and pptp version
- * - make argument list of pptp_{out,in}bound_packet() shorter
- * - move to C99 style initializers
- * - print version number at module loadtime
- * 2003-09-22 - Version 1.5
- * - use SNATed tcp sourceport as callid, since we get called before
- * TCP header is mangled (Philip Craig <philipc@snapgear.com>)
- * 2004-10-22 - Version 2.0
- * - kernel 2.6.x version
- * 2005-06-10 - Version 3.0
- * - kernel >= 2.6.11 version,
- * funded by Oxcoda NetBox Blue (http://www.netboxblue.com/)
- *

- * NAT protocol helper module for GRE.
- *
- * GRE is a generic encapsulation protocol, which is generally not very
- * suited for NAT, as it has no protocol-specific part as port numbers.
- *
- * It has an optional key field, which may help us distinguishing two
- * connections between the same two hosts.
- *
- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
- *
- * PPTP is built on top of a modified version of GRE, and has a mandatory
- * field called "CallID", which serves us for the same purpose as the key
- * field in plain GRE.
- *
- * Documentation about PPTP can be found in RFC 2637

-/*
- * ip_nat_snmp_basic.c
- *
- * Basic SNMP Application Layer Gateway
- *
- * This IP NAT module is intended for use with SNMP network
- * discovery and monitoring applications where target networks use
- * conflicting private address realms.
- *
- * Static NAT is used to remap the networks from the view of the network
- * management system at the IP layer, and this module remaps some application
- * layer addresses to match.
- *
- * The simplest form of ALG is performed, where only tagged IP addresses
- * are modified. The module does not need to be MIB aware and only scans
- * messages at the ASN.1/BER level.
- *
- * Currently, only SNMPv1 and SNMPv2 are supported.
- *
- * More information on ALG and associated issues can be found in
- * RFC 2962
- *
- * The ASB.1/BER parsing code is derived from the gxsnmp package by Gregory
- * McLean & Jochen Friedrich, stripped down for use in the kernel.

- *
- * Thu 21 Mar 2002 Harald Welte <laforge@gnumonks.org>
- * - Port to newnat API
- *
- * This module currently supports DNAT:
- * iptables -t nat -A PREROUTING -d x.x.x.x -j DNAT --to-dest x.x.x.y
- *
- * and SNAT:
- * iptables -t nat -A POSTROUTING { -j MASQUERADE , -j SNAT --to-source x.x.x.x }
- *
- * It has not been tested with
- * -j SNAT --to-source x.x.x.x-x.x.x.y since I only have one external ip
- * If you do test this please let me know if it works or not.

+ * window (but not to or beyond highest sequence sent before RTO):
+ * On First ACK, send two new segments out.
+ * On Second ACK, RTO was likely spurious. Do spurious response (response
+ * algorithm is not part of the F-RTO detection algorithm
+ * given in RFC4138 but can be selected separately).
+ * Otherwise (basically on duplicate ACK), RTO was (likely) caused by a loss
+ * and TCP falls back to conventional RTO recovery. F-RTO allows overriding
+ * of Nagle, this is done using frto_counter states 2 and 3, when a new data
+ * segment of any size sent during F-RTO, state 2 is upgraded to 3.
+ *
+ * Rationale: if the RTO was spurious, new ACKs should arrive from the
+ * original window even after we transmit two new data segments.
+ *
+ * SACK version:
+ * on first step, wait until first cumulative ACK arrives, then move to
+ * the second step. In second step, the next ACK decides.
+ *
+ * F-RTO is implemented (mainly) in four functions:
+ * - tcp_use_frto() is used to determine if TCP is can use F-RTO
+ * - tcp_enter_frto() prepares TCP state on RTO if F-RTO is used, it is
+ * called when tcp_use_frto() showed green light
+ * - tcp_process_frto() handles incoming ACKs during F-RTO algorithm
+ * - tcp_enter_frto_loss() is called if there is not enough evidence
+ * to prove that the RTO is indeed spurious. It transfers the control

+ * For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the
+ * US-ASCII string:
+ *
+ * h1.h2.h3.h4.p1.p2
+ *
+ * The prefix, "h1.h2.h3.h4", is the standard textual form for
+ * representing an IPv4 address, which is always four octets long.
+ * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
+ * the first through fourth octets each converted to ASCII-decimal.
+ * Assuming big-endian ordering, p1 and p2 are, respectively, the first
+ * and second octets each converted to ASCII-decimal. For example, if a
+ * host, in big-endian order, has an address of 0x0A010307 and there is
+ * a service listening on, in big endian order, port 0x020F (decimal
+ * 527), then the complete universal address is "10.1.3.7.2.15".
+ *
+ * ...
+ *
+ * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
+ * US-ASCII string:
+ *
+ * x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
+ *
+ * The suffix "p1.p2" is the service port, and is computed the same way
+ * as with universal addresses for TCP and UDP over IPv4. The prefix,
+ * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
+ * representing an IPv6 address as defined in Section 2.2 of [RFC2373].
+ * Additionally, the two alternative forms specified in Section 2.2 of
+ * [RFC2373] are also acceptable.
