+Description:
+ A raw device name of a disk does not always point a same disk
+ each boot-up time. Therefore, users have to use persistent
+ device names, which udev creates when the kernel finds a disk,
+ instead of raw device name. However, kernel doesn't show those
+ persistent names on its messages (e.g. dmesg).
+ This file can store an alias of the disk and it would be
+ appeared in kernel messages if it is set. A disk can have an
+ alias which length is up to 255bytes. Users can use alphabets,
+ numbers, "-" and "_" in alias name. This file is writeonce.

+Introduction
+============
+
+The more-sophisticated device-mapper targets require complex metadata
+that is managed in kernel. In late 2010 we were seeing that various
+different targets were rolling their own data strutures, for example:
+
+- Mikulas Patocka's multisnap implementation
+- Heinz Mauelshagen's thin provisioning target
+- Another btree-based caching target posted to dm-devel
+- Another multi-snapshot target based on a design of Daniel Phillips
+
+Maintaining these data structures takes a lot of work, so if possible
+we'd like to reduce the number.
+
+The persistent-data library is an attempt to provide a re-usable
+framework for people who want to store metadata in device-mapper
+targets. It's currently used by the thin-provisioning target and an
+upcoming hierarchical storage target.
+
+Overview
+========
+
+The main documentation is in the header files which can all be found
+under drivers/md/persistent-data.
+
+The block manager
+-----------------
+
+dm-block-manager.[hc]
+
+This provides access to the data on disk in fixed sized-blocks. There
+is a read/write locking interface to prevent concurrent accesses, and
+keep data that is being used in the cache.
+
+Clients of persistent-data are unlikely to use this directly.
+
+The transaction manager
+-----------------------
+
+dm-transaction-manager.[hc]
+
+This restricts access to blocks and enforces copy-on-write semantics.
+The only way you can get hold of a writable block through the
+transaction manager is by shadowing an existing block (ie. doing
+copy-on-write) or allocating a fresh one. Shadowing is elided within
+the same transaction so performance is reasonable. The commit method
+ensures that all data is flushed before it writes the superblock.
+On power failure your metadata will be as it was when last committed.
+
+The Space Maps
+--------------
+
+dm-space-map.h
+dm-space-map-metadata.[hc]
+dm-space-map-disk.[hc]
+
+On-disk data structures that keep track of reference counts of blocks.
+Also acts as the allocator of new blocks. Currently two
+implementations: a simpler one for managing blocks on a different
+device (eg. thinly-provisioned data blocks); and one for managing
+the metadata space. The latter is complicated by the need to store
+its own data within the space it's managing.
+
+The data structures
+-------------------
+
+dm-btree.[hc]
+dm-btree-remove.c
+dm-btree-spine.c
+dm-btree-internal.h
+
+Currently there is only one data structure, a hierarchical btree.
+There are plans to add more. For example, something with an
+array-like interface would see a lot of use.
+
+The btree is 'hierarchical' in that you can define it to be composed
+of nested btrees, and take multiple keys. For example, the
+thin-provisioning target uses a btree with two levels of nesting.
+The first maps a device id to a mapping tree, and that in turn maps a
+virtual block to a physical block.
+
+Values stored in the btrees can have arbitrary size. Keys are always
+64bits, although nesting allows you to use multiple keys.

+implementation of snapshots, is that it allows many virtual devices to
+be stored on the same data volume. This simplifies administration and
+allows the sharing of data between volumes, thus reducing disk usage.
+
+Another significant feature is support for an arbitrary depth of
+recursive snapshots (snapshots of snapshots of snapshots ...). The
+previous implementation of snapshots did this by chaining together
+lookup tables, and so performance was O(depth). This new
+implementation uses a single data structure to avoid this degradation
+with depth. Fragmentation may still be an issue, however, in some
+scenarios.
+
+Metadata is stored on a separate device from data, giving the
+administrator some freedom, for example to:
+
+- Improve metadata resilience by storing metadata on a mirrored volume
+ but data on a non-mirrored one.
+
+- Improve performance by storing the metadata on SSD.
+
+Status
+======
+
+These targets are very much still in the EXPERIMENTAL state. Please
+do not yet rely on them in production. But do experiment and offer us
+feedback. Different use cases will have different performance
+characteristics, for example due to fragmentation of the data volume.
+
+If you find this software is not performing as expected please mail
+dm-devel@redhat.com with details and we'll try our best to improve
+things for you.
+
+Userspace tools for checking and repairing the metadata are under
+development.
+
+Cookbook
+========
+
+This section describes some quick recipes for using thin provisioning.
+They use the dmsetup program to control the device-mapper driver
+directly. End users will be advised to use a higher-level volume
+manager such as LVM2 once support has been added.
+
+Pool device
+-----------
+
+The pool device ties together the metadata volume and the data volume.
+It maps I/O linearly to the data volume and updates the metadata via
+two mechanisms:
+
+- Function calls from the thin targets
+
+- Device-mapper 'messages' from userspace which control the creation of new
+ virtual devices amongst other things.
+
+Setting up a fresh pool device
+------------------------------
+
+Setting up a pool device requires a valid metadata device, and a
+data device. If you do not have an existing metadata device you can
+make one by zeroing the first 4k to indicate empty metadata.
+
+ dd if=/dev/zero of=$metadata_dev bs=4096 count=1
+
+The amount of metadata you need will vary according to how many blocks
+are shared between thin devices (i.e. through snapshots). If you have
+less sharing than average you'll need a larger-than-average metadata device.
+
+As a guide, we suggest you calculate the number of bytes to use in the
+metadata device as 48 * $data_dev_size / $data_block_size but round it up
+to 2MB if the answer is smaller. The largest size supported is 16GB.
+
+If you're creating large numbers of snapshots which are recording large
+amounts of change, you may need find you need to increase this.
+
+Reloading a pool table
+----------------------
+
+You may reload a pool's table, indeed this is how the pool is resized
+if it runs out of space. (N.B. While specifying a different metadata
+device when reloading is not forbidden at the moment, things will go
+wrong if it does not route I/O to exactly the same on-disk location as
+previously.)
+
+Using an existing pool device
+-----------------------------
+
+ dmsetup create pool \
+ --table "0 20971520 thin-pool $metadata_dev $data_dev \
+ $data_block_size $low_water_mark"
+
+$data_block_size gives the smallest unit of disk space that can be
+allocated at a time expressed in units of 512-byte sectors. People
+primarily interested in thin provisioning may want to use a value such
+as 1024 (512KB). People doing lots of snapshotting may want a smaller value
+such as 128 (64KB). If you are not zeroing newly-allocated data,
+a larger $data_block_size in the region of 256000 (128MB) is suggested.
+$data_block_size must be the same for the lifetime of the
+metadata device.
+
+$low_water_mark is expressed in blocks of size $data_block_size. If
+free space on the data device drops below this level then a dm event
+will be triggered which a userspace daemon should catch allowing it to
+extend the pool device. Only one such event will be sent.
+Resuming a device with a new table itself triggers an event so the
+userspace daemon can use this to detect a situation where a new table
+already exceeds the threshold.
+
+Thin provisioning
+-----------------
+
+i) Creating a new thinly-provisioned volume.
+
+ To create a new thinly- provisioned volume you must send a message to an
+ active pool device, /dev/mapper/pool in this example.
+
+ dmsetup message /dev/mapper/pool 0 "create_thin 0"
+
+ Here '0' is an identifier for the volume, a 24-bit number. It's up
+ to the caller to allocate and manage these identifiers. If the
+ identifier is already in use, the message will fail with -EEXIST.
+
+ii) Using a thinly-provisioned volume.
+
+ Thinly-provisioned volumes are activated using the 'thin' target:
+
+ dmsetup create thin --table "0 2097152 thin /dev/mapper/pool 0"
+
+ The last parameter is the identifier for the thinp device.
+
+Internal snapshots
+------------------
+
+i) Creating an internal snapshot.
+
+ Snapshots are created with another message to the pool.
+
+ N.B. If the origin device that you wish to snapshot is active, you
+ must suspend it before creating the snapshot to avoid corruption.
+ This is NOT enforced at the moment, so please be careful!
+
+ dmsetup suspend /dev/mapper/thin
+ dmsetup message /dev/mapper/pool 0 "create_snap 1 0"
+ dmsetup resume /dev/mapper/thin
+
+ Here '1' is the identifier for the volume, a 24-bit number. '0' is the
+ identifier for the origin device.
+
+ii) Using an internal snapshot.
+
+ Once created, the user doesn't have to worry about any connection
+ between the origin and the snapshot. Indeed the snapshot is no
+ different from any other thinly-provisioned device and can be
+ snapshotted itself via the same method. It's perfectly legal to
+ have only one of them active, and there's no ordering requirement on
+ activating or removing them both. (This differs from conventional
+ device-mapper snapshots.)
+
+ Activate it exactly the same way as any other thinly-provisioned volume:
+
+ dmsetup create snap --table "0 2097152 thin /dev/mapper/pool 1"
+
+Deactivation
+------------
+
+All devices using a pool must be deactivated before the pool itself
+can be.
+
+ dmsetup remove thin
+ dmsetup remove snap
+ dmsetup remove pool
+
+Reference
+=========
+
+'thin-pool' target
+------------------
+
+i) Constructor
+
+ thin-pool <metadata dev> <data dev> <data block size (sectors)> \
+ <low water mark (blocks)> [<number of feature args> [<arg>]*]
+
+ Optional feature arguments:
+ - 'skip_block_zeroing': skips the zeroing of newly-provisioned blocks.
+
+ Data block size must be between 64KB (128 sectors) and 1GB
+ (2097152 sectors) inclusive.
+
+
+ii) Status
+
+ <transaction id> <used metadata blocks>/<total metadata blocks>
+ <used data blocks>/<total data blocks> <held metadata root>
+
+
+ transaction id:
+ A 64-bit number used by userspace to help synchronise with metadata
+ from volume managers.
+
+ used data blocks / total data blocks
+ If the number of free blocks drops below the pool's low water mark a
+ dm event will be sent to userspace. This event is edge-triggered and
+ it will occur only once after each resume so volume manager writers
+ should register for the event and then check the target's status.
+
+ held metadata root:
+ The location, in sectors, of the metadata root that has been
+ 'held' for userspace read access. '-' indicates there is no
+ held root. This feature is not yet implemented so '-' is
+ always returned.
+
+iii) Messages
+
+ create_thin <dev id>
+
+ Create a new thinly-provisioned device.
+ <dev id> is an arbitrary unique 24-bit identifier chosen by
+ the caller.
+
+ create_snap <dev id> <origin id>
+
+ Create a new snapshot of another thinly-provisioned device.
+ <dev id> is an arbitrary unique 24-bit identifier chosen by
+ the caller.
+ <origin id> is the identifier of the thinly-provisioned device
+ of which the new device will be a snapshot.
+
+ delete <dev id>
+
+ Deletes a thin device. Irreversible.
+
+ trim <dev id> <new size in sectors>
+
+ Delete mappings from the end of a thin device. Irreversible.
+ You might want to use this if you're reducing the size of
+ your thinly-provisioned device. In many cases, due to the
+ sharing of blocks between devices, it is not possible to
+ determine in advance how much space 'trim' will release. (In
+ future a userspace tool might be able to perform this
+ calculation.)
+
+ set_transaction_id <current id> <new id>
+
+ Userland volume managers, such as LVM, need a way to
+ synchronise their external metadata with the internal metadata of the
+ pool target. The thin-pool target offers to store an
+ arbitrary 64-bit transaction id and return it on the target's
+ status line. To avoid races you must provide what you think
+ the current transaction id is when you change it with this
+ compare-and-swap message.
+
+'thin' target
+-------------
+
+i) Constructor
+
+ thin <pool dev> <dev id>
+
+ pool dev:
+ the thin-pool device, e.g. /dev/mapper/my_pool or 253:0
+
+ dev id:
+ the internal device identifier of the device to be
+ activated.
+
+The pool doesn't store any size against the thin devices. If you
+load a thin target that is smaller than you've been using previously,
+then you'll have no access to blocks mapped beyond the end. If you
+load a target that is bigger than before, then extra blocks will be
+provisioned as and when needed.
+
+If you wish to reduce the size of your thin device and potentially
+regain some space then send the 'trim' message to the pool.
+
+ii) Status
+
+ <nr mapped sectors> <highest mapped sector>

+* ARM Generic Interrupt Controller
+
+ARM SMP cores are often associated with a GIC, providing per processor
+interrupts (PPI), shared processor interrupts (SPI) and software
+generated interrupts (SGI).
+
+Primary GIC is attached directly to the CPU and typically has PPIs and SGIs.
+Secondary GICs are cascaded into the upward interrupt controller and do not
+have PPIs or SGIs.
+
+Main node required properties:
+
+- compatible : should be one of:
+ "arm,cortex-a9-gic"
+ "arm,arm11mp-gic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 3.
+
+ The 1st cell is the interrupt type; 0 for SPI interrupts, 1 for PPI
+ interrupts.
+
+ The 2nd cell contains the interrupt number for the interrupt type.
+ SPI interrupts are in the range [0-987]. PPI interrupts are in the
+ range [0-15].
+
+ The 3rd cell is the flags, encoded as follows:
+ bits[3:0] trigger type and level flags.
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+ bits[15:8] PPI interrupt cpu mask. Each bit corresponds to each of
+ the 8 possible cpus attached to the GIC. A bit set to '1' indicated
+ the interrupt is wired to that CPU. Only valid for PPI interrupts.
+
+- reg : Specifies base physical address(s) and size of the GIC registers. The
+ first region is the GIC distributor register base and size. The 2nd region is
+ the GIC cpu interface register base and size.
+
+Optional
+- interrupts : Interrupt source of the parent interrupt controller. Only
+ present on secondary GICs.
+
+Example:
+
+ intc: interrupt-controller@fff11000 {
+ compatible = "arm,cortex-a9-gic";
+ #interrupt-cells = <3>;
+ #address-cells = <1>;
+ interrupt-controller;

+
+The Freescale hypervisor and msi-address-64
+-------------------------------------------
+Normally, PCI devices have access to all of CCSR via an ATMU mapping. The
+Freescale MSI driver calculates the address of MSIIR (in the MSI register
+block) and sets that address as the MSI message address.
+
+In a virtualized environment, the hypervisor may need to create an IOMMU
+mapping for MSIIR. The Freescale ePAPR hypervisor has this requirement
+because of hardware limitations of the Peripheral Access Management Unit
+(PAMU), which is currently the only IOMMU that the hypervisor supports.
+The ATMU is programmed with the guest physical address, and the PAMU
+intercepts transactions and reroutes them to the true physical address.
+
+In the PAMU, each PCI controller is given only one primary window. The
+PAMU restricts DMA operations so that they can only occur within a window.
+Because PCI devices must be able to DMA to memory, the primary window must
+be used to cover all of the guest's memory space.
+
+PAMU primary windows can be divided into 256 subwindows, and each
+subwindow can have its own address mapping ("guest physical" to "true
+physical"). However, each subwindow has to have the same alignment, which
+means they cannot be located at just any address. Because of these
+restrictions, it is usually impossible to create a 4KB subwindow that
+covers MSIIR where it's normally located.
+
+Therefore, the hypervisor has to create a subwindow inside the same
+primary window used for memory, but mapped to the MSIR block (where MSIIR
+lives). The first subwindow after the end of guest memory is used for
+this. The address specified in the msi-address-64 property is the PCI
+address of MSIIR. The hypervisor configures the PAMU to map that address to
+the true physical address of MSIIR.

-What: sys_sysctl
-When: September 2010
-Option: CONFIG_SYSCTL_SYSCALL
-Why: The same information is available in a more convenient from
- /proc/sys, and none of the sysctl variables appear to be
- important performance wise.
-
- Binary sysctls are a long standing source of subtle kernel
- bugs and security issues.
-
- When I looked several months ago all I could find after
- searching several distributions were 5 user space programs and
- glibc (which falls back to /proc/sys) using this syscall.
-
- The man page for sysctl(2) documents it as unusable for user
- space programs.
-
- sysctl(2) is not generally ABI compatible to a 32bit user
- space application on a 64bit and a 32bit kernel.
-
- For the last several months the policy has been no new binary
- sysctls and no one has put forward an argument to use them.
-
- Binary sysctls issues seem to keep happening appearing so
- properly deprecating them (with a warning to user space) and a
- 2 year grace warning period will mean eventually we can kill
- them and end the pain.
-
- In the mean time individual binary sysctls can be dealt with
- in a piecewise fashion.

+7.2 Native absolute mode 6 byte packet format
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+v4 hardware is a true multitouch touchpad, capable of tracking up to 5 fingers.
+Unfortunately, due to PS/2's limited bandwidth, its packet format is rather
+complex.
+
+Whenever the numbers or identities of the fingers changes, the hardware sends a
+status packet to indicate how many and which fingers is on touchpad, followed by
+head packets or motion packets. A head packet contains data of finger id, finger
+position (absolute x, y values), width, and pressure. A motion packet contains
+two fingers' position delta.
+
+For example, when status packet tells there are 2 fingers on touchpad, then we
+can expect two following head packets. If the finger status doesn't change,
+the following packets would be motion packets, only sending delta of finger
+position, until we receive a status packet.
+
+One exception is one finger touch. when a status packet tells us there is only
+one finger, the hardware would just send head packets afterwards.

+RapidIO subsystem mport driver for IDT Tsi721 PCI Express-to-SRIO bridge.
+=========================================================================
+
+I. Overview
+
+This driver implements all currently defined RapidIO mport callback functions.
+It supports maintenance read and write operations, inbound and outbound RapidIO
+doorbells, inbound maintenance port-writes and RapidIO messaging.
+
+To generate SRIO maintenance transactions this driver uses one of Tsi721 DMA
+channels. This mechanism provides access to larger range of hop counts and
+destination IDs without need for changes in outbound window translation.
+
+RapidIO messaging support uses dedicated messaging channels for each mailbox.
+For inbound messages this driver uses destination ID matching to forward messages
+into the corresponding message queue. Messaging callbacks are implemented to be
+fully compatible with RIONET driver (Ethernet over RapidIO messaging services).
+
+II. Known problems
+
+ None.
+
+III. To do
+
+ Add DMA data transfers (non-messaging).
+ Add inbound region (SRIO-to-PCIe) mapping.
+
+IV. Version History
+
+ 1.0.0 - Initial driver release.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+Operating FCoE using bnx2fc
+===========================
+Broadcom FCoE offload through bnx2fc is full stateful hardware offload that
+cooperates with all interfaces provided by the Linux ecosystem for FC/FCoE and
+SCSI controllers. As such, FCoE functionality, once enabled is largely
+transparent. Devices discovered on the SAN will be registered and unregistered
+automatically with the upper storage layers.
+
+Despite the fact that the Broadcom's FCoE offload is fully offloaded, it does
+depend on the state of the network interfaces to operate. As such, the network
+interface (e.g. eth0) associated with the FCoE offload initiator must be 'up'.
+It is recommended that the network interfaces be configured to be brought up
+automatically at boot time.
+
+Furthermore, the Broadcom FCoE offload solution creates VLAN interfaces to
+support the VLANs that have been discovered for FCoE operation (e.g.
+eth0.1001-fcoe). Do not delete or disable these interfaces or FCoE operation
+will be disrupted.
+
+Driver Usage Model:
+===================
+
+1. Ensure that fcoe-utils package is installed.
+
+2. Configure the interfaces on which bnx2fc driver has to operate on.
+Here are the steps to configure:
+ a. cd /etc/fcoe
+ b. copy cfg-ethx to cfg-eth5 if FCoE has to be enabled on eth5.
+ c. Repeat this for all the interfaces where FCoE has to be enabled.
+ d. Edit all the cfg-eth files to set "no" for DCB_REQUIRED** field, and
+ "yes" for AUTO_VLAN.
+ e. Other configuration parameters should be left as default
+
+3. Ensure that "bnx2fc" is in SUPPORTED_DRIVERS list in /etc/fcoe/config.
+
+4. Start fcoe service. (service fcoe start). If Broadcom devices are present in
+the system, bnx2fc driver would automatically claim the interfaces, starts vlan
+discovery and log into the targets.
+
+5. "Symbolic Name" in 'fcoeadm -i' output would display if bnx2fc has claimed
+the interface.
+Eg:
+[root@bh2 ~]# fcoeadm -i
+ Description: NetXtreme II BCM57712 10 Gigabit Ethernet
+ Revision: 01
+ Manufacturer: Broadcom Corporation
+ Serial Number: 0010186FD558

+ Speed: 10 Gbit
+ Supported Speed: 10 Gbit
+ MaxFrameSize: 2048
+ FC-ID (Port ID): 0x0F0377
+ State: Online
+
+6. Verify the vlan discovery is performed by running ifconfig and notice
+<INTERFACE>.<VLAN>-fcoe interfaces are automatically created.
+
+Refer to fcoeadm manpage for more information on fcoeadm operations to
+create/destroy interfaces or to display lun/target information.
+
+NOTE:
+====
+** Broadcom FCoE capable devices implement a DCBX/LLDP client on-chip. Only one
+LLDP client is allowed per interface. For proper operation all host software
+based DCBX/LLDP clients (e.g. lldpad) must be disabled. To disable lldpad on a
+given interface, run the following command:
+
+lldptool set-lldp -i <interface_name> adminStatus=disabled

+Converting old watchdog drivers to the watchdog framework
+by Wolfram Sang <w.sang@pengutronix.de>
+=========================================================
+
+Before the watchdog framework came into the kernel, every driver had to
+implement the API on its own. Now, as the framework factored out the common
+components, those drivers can be lightened making it a user of the framework.
+This document shall guide you for this task. The necessary steps are described
+as well as things to look out for.
+
+
+Remove the file_operations struct
+---------------------------------
+
+Old drivers define their own file_operations for actions like open(), write(),
+etc... These are now handled by the framework and just call the driver when
+needed. So, in general, the 'file_operations' struct and assorted functions can
+go. Only very few driver-specific details have to be moved to other functions.
+Here is a overview of the functions and probably needed actions:
+
+- open: Everything dealing with resource management (file-open checks, magic
+ close preparations) can simply go. Device specific stuff needs to go to the
+ driver specific start-function. Note that for some drivers, the start-function
+ also serves as the ping-function. If that is the case and you need start/stop
+ to be balanced (clocks!), you are better off refactoring a separate start-function.
+
+- close: Same hints as for open apply.
+
+- write: Can simply go, all defined behaviour is taken care of by the framework,
+ i.e. ping on write and magic char ('V') handling.
+
+- ioctl: While the driver is allowed to have extensions to the IOCTL interface,
+ the most common ones are handled by the framework, supported by some assistance
+ from the driver:
+
+ WDIOC_GETSUPPORT:
+ Returns the mandatory watchdog_info struct from the driver
+
+ WDIOC_GETSTATUS:
+ Needs the status-callback defined, otherwise returns 0
+
+ WDIOC_GETBOOTSTATUS:
+ Needs the bootstatus member properly set. Make sure it is 0 if you
+ don't have further support!
+
+ WDIOC_SETOPTIONS:
+ No preparations needed
+
+ WDIOC_KEEPALIVE:
+ If wanted, options in watchdog_info need to have WDIOF_KEEPALIVEPING
+ set
+
+ WDIOC_SETTIMEOUT:
+ Options in watchdog_info need to have WDIOF_SETTIMEOUT set
+ and a set_timeout-callback has to be defined. The core will also
+ do limit-checking, if min_timeout and max_timeout in the watchdog
+ device are set. All is optional.
+
+ WDIOC_GETTIMEOUT:
+ No preparations needed
+
+ Other IOCTLs can be served using the ioctl-callback. Note that this is mainly
+ intended for porting old drivers; new drivers should not invent private IOCTLs.
+ Private IOCTLs are processed first. When the callback returns with
+ -ENOIOCTLCMD, the IOCTLs of the framework will be tried, too. Any other error
+ is directly given to the user.
+
+Example conversion:
+
+-static const struct file_operations s3c2410wdt_fops = {
+- .owner = THIS_MODULE,
+- .llseek = no_llseek,
+- .write = s3c2410wdt_write,
+- .unlocked_ioctl = s3c2410wdt_ioctl,
+- .open = s3c2410wdt_open,
+- .release = s3c2410wdt_release,
+-};
+
+Check the functions for device-specific stuff and keep it for later
+refactoring. The rest can go.
+
+
+Remove the miscdevice
+---------------------
+
+Since the file_operations are gone now, you can also remove the 'struct
+miscdevice'. The framework will create it on watchdog_dev_register() called by
+watchdog_register_device().
+
+-static struct miscdevice s3c2410wdt_miscdev = {
+- .minor = WATCHDOG_MINOR,
+- .name = "watchdog",
+- .fops = &s3c2410wdt_fops,
+-};
+
+
+Remove obsolete includes and defines
+------------------------------------
+
+Because of the simplifications, a few defines are probably unused now. Remove
+them. Includes can be removed, too. For example:
+
+- #include <linux/fs.h>
+- #include <linux/miscdevice.h> (if MODULE_ALIAS_MISCDEV is not used)
+- #include <linux/uaccess.h> (if no custom IOCTLs are used)
+
+
+Add the watchdog operations
+---------------------------
+
+All possible callbacks are defined in 'struct watchdog_ops'. You can find it
+explained in 'watchdog-kernel-api.txt' in this directory. start(), stop() and
+owner must be set, the rest are optional. You will easily find corresponding
+functions in the old driver. Note that you will now get a pointer to the
+watchdog_device as a parameter to these functions, so you probably have to
+change the function header. Other changes are most likely not needed, because
+here simply happens the direct hardware access. If you have device-specific
+code left from the above steps, it should be refactored into these callbacks.
+
+Here is a simple example:
+
++static struct watchdog_ops s3c2410wdt_ops = {
++ .owner = THIS_MODULE,
++ .start = s3c2410wdt_start,
++ .stop = s3c2410wdt_stop,
++ .ping = s3c2410wdt_keepalive,
++ .set_timeout = s3c2410wdt_set_heartbeat,
++};
+
+A typical function-header change looks like:
+
+-static void s3c2410wdt_keepalive(void)
++static int s3c2410wdt_keepalive(struct watchdog_device *wdd)
+ {
+...
++
++ return 0;
+ }
+
+...
+
+- s3c2410wdt_keepalive();
++ s3c2410wdt_keepalive(&s3c2410_wdd);
+
+
+Add the watchdog device
+-----------------------
+
+Now we need to create a 'struct watchdog_device' and populate it with the
+necessary information for the framework. The struct is also explained in detail
+in 'watchdog-kernel-api.txt' in this directory. We pass it the mandatory
+watchdog_info struct and the newly created watchdog_ops. Often, old drivers
+have their own record-keeping for things like bootstatus and timeout using
+static variables. Those have to be converted to use the members in
+watchdog_device. Note that the timeout values are unsigned int. Some drivers
+use signed int, so this has to be converted, too.
+
+Here is a simple example for a watchdog device:
+
++static struct watchdog_device s3c2410_wdd = {
++ .info = &s3c2410_wdt_ident,
++ .ops = &s3c2410wdt_ops,
++};
+
+
+Register the watchdog device
+----------------------------
+
+Replace misc_register(&miscdev) with watchdog_register_device(&watchdog_dev).
+Make sure the return value gets checked and the error message, if present,
+still fits. Also convert the unregister case.
+
+- ret = misc_register(&s3c2410wdt_miscdev);
++ ret = watchdog_register_device(&s3c2410_wdd);
+
+...
+
+- misc_deregister(&s3c2410wdt_miscdev);
++ watchdog_unregister_device(&s3c2410_wdd);
+
+
+Update the Kconfig-entry
+------------------------
+
+The entry for the driver now needs to select WATCHDOG_CORE:
+
++ select WATCHDOG_CORE
+
+
+Create a patch and send it to upstream
+--------------------------------------
+
+Make sure you understood Documentation/SubmittingPatches and send your patch to
+linux-watchdog@vger.kernel.org. We are looking forward to it :)

+ * This file contains test code for ARM kprobes.
+ *
+ * The top level function run_all_tests() executes tests for all of the
+ * supported instruction sets: ARM, 16-bit Thumb, and 32-bit Thumb. These tests
+ * fall into two categories; run_api_tests() checks basic functionality of the
+ * kprobes API, and run_test_cases() is a comprehensive test for kprobes
+ * instruction decoding and simulation.
+ *
+ * run_test_cases() first checks the kprobes decoding table for self consistency
+ * (using table_test()) then executes a series of test cases for each of the CPU
+ * instruction forms. coverage_start() and coverage_end() are used to verify
+ * that these test cases cover all of the possible combinations of instructions
+ * described by the kprobes decoding tables.
+ *
+ * The individual test cases are in kprobes-test-arm.c and kprobes-test-thumb.c
+ * which use the macros defined in kprobes-test.h. The rest of this
+ * documentation will describe the operation of the framework used by these
+ * test cases.

+
+/*
+ * TESTING METHODOLOGY
+ * -------------------
+ *
+ * The methodology used to test an ARM instruction 'test_insn' is to use
+ * inline assembler like:
+ *
+ * test_before: nop
+ * test_case: test_insn
+ * test_after: nop
+ *
+ * When the test case is run a kprobe is placed of each nop. The
+ * post-handler of the test_before probe is used to modify the saved CPU
+ * register context to that which we require for the test case. The
+ * pre-handler of the of the test_after probe saves a copy of the CPU
+ * register context. In this way we can execute test_insn with a specific
+ * register context and see the results afterwards.
+ *
+ * To actually test the kprobes instruction emulation we perform the above
+ * step a second time but with an additional kprobe on the test_case
+ * instruction itself. If the emulation is accurate then the results seen
+ * by the test_after probe will be identical to the first run which didn't
+ * have a probe on test_case.
+ *
+ * Each test case is run several times with a variety of variations in the
+ * flags value of stored in CPSR, and for Thumb code, different ITState.
+ *
+ * For instructions which can modify PC, a second test_after probe is used
+ * like this:
+ *
+ * test_before: nop
+ * test_case: test_insn
+ * test_after: nop
+ * b test_done
+ * test_after2: nop
+ * test_done:
+ *
+ * The test case is constructed such that test_insn branches to
+ * test_after2, or, if testing a conditional instruction, it may just
+ * continue to test_after. The probes inserted at both locations let us
+ * determine which happened. A similar approach is used for testing
+ * backwards branches...
+ *
+ * b test_before
+ * b test_done @ helps to cope with off by 1 branches
+ * test_after2: nop
+ * b test_done
+ * test_before: nop
+ * test_case: test_insn
+ * test_after: nop
+ * test_done:
+ *
+ * The macros used to generate the assembler instructions describe above
+ * are TEST_INSTRUCTION, TEST_BRANCH_F (branch forwards) and TEST_BRANCH_B
+ * (branch backwards). In these, the local variables numbered 1, 50, 2 and
+ * 99 represent: test_before, test_case, test_after2 and test_done.
+ *
+ * FRAMEWORK
+ * ---------
+ *
+ * Each test case is wrapped between the pair of macros TESTCASE_START and
+ * TESTCASE_END. As well as performing the inline assembler boilerplate,
+ * these call out to the kprobes_test_case_start() and
+ * kprobes_test_case_end() functions which drive the execution of the test
+ * case. The specific arguments to use for each test case are stored as
+ * inline data constructed using the various TEST_ARG_* macros. Putting
+ * this all together, a simple test case may look like:
+ *
+ * TESTCASE_START("Testing mov r0, r7")
+ * TEST_ARG_REG(7, 0x12345678) // Set r7=0x12345678
+ * TEST_ARG_END("")
+ * TEST_INSTRUCTION("mov r0, r7")
+ * TESTCASE_END
+ *
+ * Note, in practice the single convenience macro TEST_R would be used for this
+ * instead.
+ *
+ * The above would expand to assembler looking something like:
+ *
+ * @ TESTCASE_START
+ * bl __kprobes_test_case_start
+ * @ start of inline data...
+ * .ascii "mov r0, r7" @ text title for test case
+ * .byte 0
+ * .align 2
+ *
+ * @ TEST_ARG_REG
+ * .byte ARG_TYPE_REG
+ * .byte 7
+ * .short 0
+ * .word 0x1234567
+ *
+ * @ TEST_ARG_END
+ * .byte ARG_TYPE_END
+ * .byte TEST_ISA @ flags, including ISA being tested
+ * .short 50f-0f @ offset of 'test_before'
+ * .short 2f-0f @ offset of 'test_after2' (if relevent)
+ * .short 99f-0f @ offset of 'test_done'
+ * @ start of test case code...
+ * 0:
+ * .code TEST_ISA @ switch to ISA being tested
+ *
+ * @ TEST_INSTRUCTION
+ * 50: nop @ location for 'test_before' probe
+ * 1: mov r0, r7 @ the test case instruction 'test_insn'
+ * nop @ location for 'test_after' probe
+ *
+ * // TESTCASE_END
+ * 2:
+ * 99: bl __kprobes_test_case_end_##TEST_ISA
+ * .code NONMAL_ISA
+ *
+ * When the above is execute the following happens...
+ *
+ * __kprobes_test_case_start() is an assembler wrapper which sets up space
+ * for a stack buffer and calls the C function kprobes_test_case_start().
+ * This C function will do some initial processing of the inline data and
+ * setup some global state. It then inserts the test_before and test_after
+ * kprobes and returns a value which causes the assembler wrapper to jump
+ * to the start of the test case code, (local label '0').
+ *
+ * When the test case code executes, the test_before probe will be hit and
+ * test_before_post_handler will call setup_test_context(). This fills the
+ * stack buffer and CPU registers with a test pattern and then processes
+ * the test case arguments. In our example there is one TEST_ARG_REG which
+ * indicates that R7 should be loaded with the value 0x12345678.
+ *
+ * When the test_before probe ends, the test case continues and executes
+ * the "mov r0, r7" instruction. It then hits the test_after probe and the
+ * pre-handler for this (test_after_pre_handler) will save a copy of the
+ * CPU register context. This should now have R0 holding the same value as
+ * R7.
+ *
+ * Finally we get to the call to __kprobes_test_case_end_{32,16}. This is
+ * an assembler wrapper which switches back to the ISA used by the test
+ * code and calls the C function kprobes_test_case_end().
+ *
+ * For each run through the test case, test_case_run_count is incremented
+ * by one. For even runs, kprobes_test_case_end() saves a copy of the
+ * register and stack buffer contents from the test case just run. It then
+ * inserts a kprobe on the test case instruction 'test_insn' and returns a
+ * value to cause the test case code to be re-run.
+ *
+ * For odd numbered runs, kprobes_test_case_end() compares the register and
+ * stack buffer contents to those that were saved on the previous even
+ * numbered run (the one without the kprobe on test_insn). These should be
+ * the same if the kprobe instruction simulation routine is correct.
+ *
+ * The pair of test case runs is repeated with different combinations of
+ * flag values in CPSR and, for Thumb, different ITState. This is
+ * controlled by test_context_cpsr().
+ *
+ * BUILDING TEST CASES
+ * -------------------
+ *
+ *
+ * As an aid to building test cases, the stack buffer is initialised with
+ * some special values:
+ *
+ * [SP+13*4] Contains SP+120. This can be used to test instructions
+ * which load a value into SP.
+ *
+ * [SP+15*4] When testing branching instructions using TEST_BRANCH_{F,B},
+ * this holds the target address of the branch, 'test_after2'.
+ * This can be used to test instructions which load a PC value
+ * from memory.

+ * This file contains clockdomains and clockdomain wakeup/sleep
+ * dependencies for the OMAP3xxx chips. Some notes:
+ *
+ * A useful validation rule for struct clockdomain: Any clockdomain
+ * referenced by a wkdep_srcs or sleepdep_srcs array must have a
+ * dep_bit assigned. So wkdep_srcs/sleepdep_srcs are really just
+ * software-controllable dependencies. Non-software-controllable
+ * dependencies do exist, but they are not encoded below (yet).
+ *
+ * The overly-specific dep_bit names are due to a bit name collision
+ * with CM_FCLKEN_{DSP,IVA2}. The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
+ * value are the same for all powerdomains: 2
+ *
+ * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
+ * sanity check?
+ * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE

+ to pass arguments to the kernel. For these, you should supply some
+ command-line options at build time by entering them here. At a
+ minimum, you should specify the memory size and the root device
+ (e.g., mem=64M root=/dev/nfs).
+

+ Enable angel debug traps (for printk's).

+ minimum value which makes sense is 2.
+
+ This is purely to save memory - each supported CPU adds
+ approximately eight kilobytes to the kernel image.

+ * Description
+ *
+ * library function for memcpy where length bytes are copied from
+ * ptr_in to ptr_out. ptr_out is returned unchanged.
+ * Allows any combination of alignment on input and output pointers
+ * and length from 0 to 2^32-1
+ *
+ * Restrictions
+ * The arrays should not overlap, the program will produce undefined output
+ * if they do.
+ * For blocks less than 16 bytes a byte by byte copy is performed. For
+ * 8byte alignments, and length multiples, a dword copy is performed up to
+ * 96bytes
+ * History
+ *
+ * DJH 5/15/09 Initial version 1.0
+ * DJH 6/ 1/09 Version 1.1 modified ABI to inlcude R16-R19
+ * DJH 7/12/09 Version 1.2 optimized codesize down to 760 was 840
+ * DJH 10/14/09 Version 1.3 added special loop for aligned case, was
+ * overreading bloated codesize back up to 892
+ * DJH 4/20/10 Version 1.4 fixed Ldword_loop_epilog loop to prevent loads
+ * occuring if only 1 left outstanding, fixes bug
+ * # 3888, corrected for all alignments. Peeled off
+ * 1 32byte chunk from kernel loop and extended 8byte
+ * loop at end to solve all combinations and prevent
+ * over read. Fixed Ldword_loop_prolog to prevent
+ * overread for blocks less than 48bytes. Reduced
+ * codesize to 752 bytes
+ * DJH 4/21/10 version 1.5 1.4 fix broke code for input block ends not
+ * aligned to dword boundaries,underwriting by 1
+ * byte, added detection for this and fixed. A
+ * little bloat.
+ * DJH 4/23/10 version 1.6 corrected stack error, R20 was not being restored
+ * always, fixed the error of R20 being modified
+ * before it was being saved
+ * Natural c model

- * 11/07/96: rewritten interrupt handling, irq lists are exists now only for

- * be careful that dev_id for this sources is unique since this the

- * free_irq. irq lists also have different irq flags:
- * - IRQ_FLG_FAST: handler is inserted at top of list (after other
- * fast handlers)
- * - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
- * they're executed irq level is set to the previous
- * one, but handlers don't need to be reentrant, if
- * reentrance occurred, slow handlers will be just
- * called again.
- * The whole interrupt handling for CIAs is moved to cia.c
- * /Roman Zippel
- *
- * 07/08/99: rewamp of the interrupt handling - we now have two types of
- * interrupts, normal and fast handlers, fast handlers being
- * marked with IRQF_DISABLED and runs with all other interrupts
- * disabled. Normal interrupts disable their own source but
- * run with all other interrupt sources enabled.
- * PORTS and EXTER interrupts are always shared even if the
- * drivers do not explicitly mark this when calling
- * request_irq which they really should do.
- * This is similar to the way interrupts are handled on all
- * other architectures and makes a ton of sense besides
- * having the advantage of making it easier to share

* <asm/atariints.h>): Autovector interrupts are 1..7, then follow ST-MFP,
* TT-MFP, SCC, and finally VME interrupts. Vector numbers for the latter can
* be allocated by atari_register_vme_int().
- *
- * Each interrupt can be of three types:
- *
- * - SLOW: The handler runs with all interrupts enabled, except the one it
- * was called by (to avoid reentering). This should be the usual method.
- * But it is currently possible only for MFP ints, since only the MFP
- * offers an easy way to mask interrupts.
- *
- * - FAST: The handler runs with all interrupts disabled. This should be used
- * only for really fast handlers, that just do actions immediately
- * necessary, and let the rest do a bottom half or task queue.
- *
- * - PRIORITIZED: The handler can be interrupted by higher-level ints
- * (greater IPL, no MFP priorities!). This is the method of choice for ints
- * which should be slow, but are not from a MFP.
- *
- * The feature of more than one handler for one int source is still there, but
- * only applicable if all handers are of the same type. To not slow down
- * processing of ints with only one handler by the chaining feature, the list
- * calling function atari_call_irq_list() is only plugged in at the time the
- * second handler is registered.
- *
- * Implementation notes: For fast-as-possible int handling, there are separate
- * entry points for each type (slow/fast/prio). The assembler handler calls
- * the irq directly in the usual case, no C wrapper is involved. In case of
- * multiple handlers, atari_call_irq_list() is registered as handler and calls
- * in turn the real irq's. To ease access from assembler level to the irq
- * function pointer and accompanying data, these two are stored in a separate
- * array, irq_handler[]. The rest of data (type, name) are put into a second
- * array, irq_param, that is accessed from C only. For each slow interrupt (32
- * in all) there are separate handler functions, which makes it possible to
- * hard-code the MFP register address and value, are necessary to mask the
- * int. If there'd be only one generic function, lots of calculations would be
- * needed to determine MFP register and int mask from the vector number :-(
- *
- * Furthermore, slow ints may not lower the IPL below its previous value
- * (before the int happened). This is needed so that an int of class PRIO, on
- * that this int may be stacked, cannot be reentered. This feature is

- * is not stacked, and the IPL is anded with 0xfbff, resulting in a new level
- * 2, which still blocks the HSYNC, but no interrupts of interest. If the
- * frame format is 0, the int is nested, and the old IPL value can be found in

- A pseudo terminal (PTY) is a software device consisting of two

- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was

- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier. All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads. This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies. See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * b = 2;
- * memory_barrier();
- * p = &b; q = p;
- * read_barrier_depends();
- * d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends(). However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * a = 2;
- * memory_barrier();
- * b = 3; y = b;
- * read_barrier_depends();
- * x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b". Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
- * in cases like this where there are no data dependencies.

+ * This is a SIMD SHA-1 implementation. It requires the Intel(R) Supplemental
+ * SSE3 instruction set extensions introduced in Intel Core Microarchitecture
+ * processors. CPUs supporting Intel(R) AVX extensions will get an additional
+ * boost.
+ *
+ * This work was inspired by the vectorized implementation of Dean Gaudet.
+ * Additional information on it can be found at:
+ * http://www.arctic.org/~dean/crypto/sha1.html
+ *
+ * It was improved upon with more efficient vectorization of the message
+ * scheduling. This implementation has also been optimized for all current and
+ * several future generations of Intel CPUs.
+ *
+ * See this article for more information about the implementation details:

+ The way to make use of this is to install the rng-tools package
+ (check your distro, or download from

+ /dev/hwrng and injects the entropy into /dev/random.

-/*
- * There are several things to be aware of that aren't at all obvious:
- *
- *
- * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
- *
- * These are some of the many terms that are thrown about that don't always
- * mean what people think they mean (Inconceivable!). In the interest of
- * creating a common ground for discussion, terms and their definitions
- * will be established.
- *
- * Memory devices: The individual chip on a memory stick. These devices
- * commonly output 4 and 8 bits each. Grouping several
- * of these in parallel provides 64 bits which is common
- * for a memory stick.
- *
- * Memory Stick: A printed circuit board that aggregates multiple
- * memory devices in parallel. This is the atomic
- * memory component that is purchaseable by Joe consumer
- * and loaded into a memory socket.
- *
- * Socket: A physical connector on the motherboard that accepts
- * a single memory stick.
- *
- * Channel: Set of memory devices on a memory stick that must be
- * grouped in parallel with one or more additional
- * channels from other memory sticks. This parallel
- * grouping of the output from multiple channels are
- * necessary for the smallest granularity of memory access.
- * Some memory controllers are capable of single channel -
- * which means that memory sticks can be loaded
- * individually. Other memory controllers are only
- * capable of dual channel - which means that memory
- * sticks must be loaded as pairs (see "socket set").
- *
- * Chip-select row: All of the memory devices that are selected together.
- * for a single, minimum grain of memory access.
- * This selects all of the parallel memory devices across
- * all of the parallel channels. Common chip-select rows
- * for single channel are 64 bits, for dual channel 128
- * bits.
- *
- * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
- * Motherboards commonly drive two chip-select pins to
- * a memory stick. A single-ranked stick, will occupy
- * only one of those rows. The other will be unused.
- *
- * Double-Ranked stick: A double-ranked stick has two chip-select rows which
- * access different sets of memory devices. The two
- * rows cannot be accessed concurrently.
- *
- * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
- * A double-sided stick has two chip-select rows which
- * access different sets of memory devices. The two
- * rows cannot be accessed concurrently. "Double-sided"
- * is irrespective of the memory devices being mounted
- * on both sides of the memory stick.
- *
- * Socket set: All of the memory sticks that are required for
- * a single memory access or all of the memory sticks
- * spanned by a chip-select row. A single socket set
- * has two chip-select rows and if double-sided sticks
- * are used these will occupy those chip-select rows.
- *
- * Bank: This term is avoided because it is unclear when
- * needing to distinguish between chip-select rows and
- * socket sets.
- *
- * Controller pages:
- *
- * Physical pages:
- *
- * Virtual pages:

- * STRUCTURE ORGANIZATION AND CHOICES

- * PS - I enjoyed writing all that about as much as you enjoyed reading it.

+ *
+ * [DevSNB-C+{W/A}] Before any depth stall flush (including those
+ * produced by non-pipelined state commands), software needs to first
+ * send a PIPE_CONTROL with no bits set except Post-Sync Operation !=
+ * 0.
+ *
+ * [Dev-SNB{W/A}]: Before a PIPE_CONTROL with Write Cache Flush Enable
+ * =1, a PIPE_CONTROL with any non-zero post-sync-op is required.
+ *
+ * And the workaround for these two requires this workaround first:
+ *
+ * [Dev-SNB{W/A}]: Pipe-control with CS-stall bit set must be sent
+ * BEFORE the pipe-control with a post-sync op and no write-cache
+ * flushes.
+ *
+ * And this last workaround is tricky because of the requirements on
+ * that bit. From section 1.4.7.2.3 "Stall" of the Sandy Bridge PRM
+ * volume 2 part 1:
+ *
+ * "1 of the following must also be set:
+ * - Render Target Cache Flush Enable ([12] of DW1)
+ * - Depth Cache Flush Enable ([0] of DW1)
+ * - Stall at Pixel Scoreboard ([1] of DW1)
+ * - Depth Stall ([13] of DW1)
+ * - Post-Sync Operation ([13] of DW1)
+ * - Notify Enable ([8] of DW1)"
+ *
+ * The cache flushes require the workaround flush that triggered this
+ * one, so we can't use it. Depth stall would trigger the same.
+ * Post-sync nonzero is what triggered this second workaround, so we
+ * can't use that one either. Notify enable is IRQs, which aren't

+ * irq is received. When the last fence waiter is gone, that IRQ is masked
+ * away.
+ *
+ * In situations where there are no waiters and we don't submit any new fences,
+ * fence objects may not be signaled. This is perfectly OK, since there are
+ * no consumers of the signaled data, but that is NOT ok when there are fence
+ * actions attached to a fence. The fencing subsystem then makes use of the
+ * FENCE_GOAL irq and sets the fence goal seqno to that of the next fence
+ * which has an action attached, and each time vmw_fences_update is called,
+ * the subsystem makes sure the fence goal seqno is updated.

- These are RF remotes with USB receivers.
- The ATI remote comes with many of ATI's All-In-Wonder video cards.
- The X10 "Lola" remote is available at:
- <http://www.x10.com/products/lola_sg1.htm>
- This driver provides mouse pointer, left and right mouse buttons,
- and maps all the other remote buttons to keypress events.
-
- To compile this driver as a module, choose M here: the module will be
- called ati_remote.

+ * As far as the metadata goes, there is:
+ *
+ * - A superblock in block zero, taking up fewer than 512 bytes for
+ * atomic writes.
+ *
+ * - A space map managing the metadata blocks.
+ *
+ * - A space map managing the data blocks.
+ *
+ * - A btree mapping our internal thin dev ids onto struct disk_device_details.
+ *
+ * - A hierarchical btree, with 2 levels which effectively maps (thin
+ * dev id, virtual block) -> block_time. Block time is a 64-bit
+ * field holding the time in the low 24 bits, and block in the top 48
+ * bits.
+ *
+ * BTrees consist solely of btree_nodes, that fill a block. Some are
+ * internal nodes, as such their values are a __le64 pointing to other
+ * nodes. Leaf nodes can store data of any reasonable size (ie. much
+ * smaller than the block size). The nodes consist of the header,
+ * followed by an array of keys, followed by an array of values. We have
+ * to binary search on the keys so they're all held together to help the
+ * cpu cache.
+ *
+ * Space maps have 2 btrees:
+ *
+ * - One maps a uint64_t onto a struct index_entry. Which points to a
+ * bitmap block, and has some details about how many free entries there
+ * are etc.
+ *
+ * - The bitmap blocks have a header (for the checksum). Then the rest
+ * of the block is pairs of bits. With the meaning being:
+ *
+ * 0 - ref count is 0
+ * 1 - ref count is 1
+ * 2 - ref count is 2
+ * 3 - ref count is higher than 2
+ *
+ * - If the count is higher than 2 then the ref count is entered in a
+ * second btree that directly maps the block_address to a uint32_t ref
+ * count.
+ *
+ * The space map metadata variant doesn't have a bitmaps btree. Instead
+ * it has one single blocks worth of index_entries. This avoids
+ * recursive issues with the bitmap btree needing to allocate space in
+ * order to insert. With a small data block size such as 64k the
+ * metadata support data devices that are hundreds of terrabytes.
+ *
+ * The space maps allocate space linearly from front to back. Space that
+ * is freed in a transaction is never recycled within that transaction.
+ * To try and avoid fragmenting _free_ space the allocator always goes
+ * back and fills in gaps.
+ *
+ * All metadata io is in THIN_METADATA_BLOCK_SIZE sized/aligned chunks
+ * from the block manager.

+ * How do we handle breaking sharing of data blocks?
+ * =================================================
+ *
+ * We use a standard copy-on-write btree to store the mappings for the
+ * devices (note I'm talking about copy-on-write of the metadata here, not
+ * the data). When you take an internal snapshot you clone the root node
+ * of the origin btree. After this there is no concept of an origin or a
+ * snapshot. They are just two device trees that happen to point to the
+ * same data blocks.
+ *
+ * When we get a write in we decide if it's to a shared data block using
+ * some timestamp magic. If it is, we have to break sharing.
+ *
+ * Let's say we write to a shared block in what was the origin. The
+ * steps are:
+ *
+ * i) plug io further to this physical block. (see bio_prison code).
+ *
+ * ii) quiesce any read io to that shared data block. Obviously
+ * including all devices that share this block. (see deferred_set code)
+ *
+ * iii) copy the data block to a newly allocate block. This step can be
+ * missed out if the io covers the block. (schedule_copy).
+ *
+ * iv) insert the new mapping into the origin's btree
+ * (process_prepared_mappings). This act of inserting breaks some
+ * sharing of btree nodes between the two devices. Breaking sharing only
+ * effects the btree of that specific device. Btrees for the other
+ * devices that share the block never change. The btree for the origin
+ * device as it was after the last commit is untouched, ie. we're using
+ * persistent data structures in the functional programming sense.
+ *
+ * v) unplug io to this physical block, including the io that triggered
+ * the breaking of sharing.
+ *
+ * Steps (ii) and (iii) occur in parallel.
+ *
+ * The metadata _doesn't_ need to be committed before the io continues. We
+ * get away with this because the io is always written to a _new_ block.
+ * If there's a crash, then:
+ *
+ * - The origin mapping will point to the old origin block (the shared
+ * one). This will contain the data as it was before the io that triggered
+ * the breaking of sharing came in.
+ *
+ * - The snap mapping still points to the old block. As it would after
+ * the commit.
+ *
+ * The downside of this scheme is the timestamp magic isn't perfect, and
+ * will continue to think that data block in the snapshot device is shared
+ * even after the write to the origin has broken sharing. I suspect data
+ * blocks will typically be shared by many different devices, so we're
+ * breaking sharing n + 1 times, rather than n, where n is the number of
+ * devices that reference this data block. At the moment I think the
+ * benefits far, far outweigh the disadvantages.

+ * Removing an entry from a btree
+ * ==============================
+ *
+ * A very important constraint for our btree is that no node, except the
+ * root, may have fewer than a certain number of entries.
+ * (MIN_ENTRIES <= nr_entries <= MAX_ENTRIES).
+ *
+ * Ensuring this is complicated by the way we want to only ever hold the
+ * locks on 2 nodes concurrently, and only change nodes in a top to bottom
+ * fashion.
+ *
+ * Each node may have a left or right sibling. When decending the spine,
+ * if a node contains only MIN_ENTRIES then we try and increase this to at
+ * least MIN_ENTRIES + 1. We do this in the following ways:
+ *
+ * [A] No siblings => this can only happen if the node is the root, in which
+ * case we copy the childs contents over the root.
+ *
+ * [B] No left sibling
+ * ==> rebalance(node, right sibling)
+ *
+ * [C] No right sibling
+ * ==> rebalance(left sibling, node)
+ *
+ * [D] Both siblings, total_entries(left, node, right) <= DEL_THRESHOLD
+ * ==> delete node adding it's contents to left and right
+ *
+ * [E] Both siblings, total_entries(left, node, right) > DEL_THRESHOLD
+ * ==> rebalance(left, node, right)
+ *
+ * After these operations it's possible that the our original node no
+ * longer contains the desired sub tree. For this reason this rebalancing
+ * is performed on the children of the current node. This also avoids
+ * having a special case for the root.
+ *
+ * Once this rebalancing has occurred we can then step into the child node
+ * for internal nodes. Or delete the entry for leaf nodes.

- Multifunction devices embed several functions (e.g. GPIOs,
- touchscreens, keyboards, current regulators, power management chips,
- etc...) in one single integrated circuit. They usually talk to the
- main CPU through one or more IRQ lines and low speed data busses (SPI,
- I2C, etc..). They appear as one single device to the main system
- through the data bus and the MFD framework allows for sub devices
- (a.k.a. functions) to appear as discrete platform devices.
- MFDs are typically found on embedded platforms.
-
- This option alone does not add any kernel code.

+ * - block erase
+ * - page write
+ * - IPL write
+ * - ECC fixing (lack of BCH algorith understanding)
+ * - powerdown / powerup
+ *
+ * The bus data width (8bits versus 16bits) is not handled (if_cfg flag), and

+ *
+ * DocG3 relies on 2 ECC algorithms, which are handled in hardware :
+ * - a 1 byte Hamming code stored in the OOB for each page
+ * - a 7 bytes BCH code stored in the OOB for each page
+ * The BCH part is only used for check purpose, no correction is available as
+ * some information is missing. What is known is that :
+ * - BCH is in GF(2^14)
+ * - BCH is over data of 520 bytes (512 page + 7 page_info bytes
+ * + 1 hamming byte)
+ * - BCH can correct up to 4 bits (t = 4)
+ * - BCH syndroms are calculated in hardware, and checked in hardware as well

+ *

+ *
+ * AD is the applied delay, in ns.

+ * if the DLL is being driven by full periods, or half that if
+ * the DLL is being driven by half periods.
+ *
+ * Let's re-arrange this in a way that's more useful to us:
+ *
+ * 8
+ * SDF = AD x ----
+ * RP
+ *
+ * The reference period is either the clock period or half that, so this
+ * is:
+ *
+ * 8 AD x DDF
+ * SDF = AD x ----- = --------
+ * f x P P
+ *
+ * where:
+ *
+ * f is 1 or 1/2, depending on how we're driving the DLL.
+ * P is the clock period.
+ * DDF is the DLL Delay Factor, a dimensionless value that
+ * incorporates all the constants in the conversion.
+ *
+ * DDF will be either 8 or 16, both of which are powers of two. We can
+ * reduce the cost of this conversion by using bit shifts instead of
+ * multiplication or division. Thus:
+ *
+ * AD << DDS
+ * SDF = ---------
+ * P
+ *
+ * or

+/*
+ * There are several places in this driver where we have to handle the OOB and
+ * block marks. This is the function where things are the most complicated, so
+ * this is where we try to explain it all. All the other places refer back to
+ * here.
+ *
+ * These are the rules, in order of decreasing importance:
+ *
+ * 1) Nothing the caller does can be allowed to imperil the block mark.
+ *
+ * 2) In read operations, the first byte of the OOB we return must reflect the
+ * true state of the block mark, no matter where that block mark appears in
+ * the physical page.
+ *
+ * 3) ECC-based read operations return an OOB full of set bits (since we never
+ * allow ECC-based writes to the OOB, it doesn't matter what ECC-based reads
+ * return).
+ *
+ * 4) "Raw" read operations return a direct view of the physical bytes in the
+ * page, using the conventional definition of which bytes are data and which
+ * are OOB. This gives the caller a way to see the actual, physical bytes
+ * in the page, without the distortions applied by our ECC engine.
+ *
+ *
+ * What we do for this specific read operation depends on two questions:
+ *
+ * 1) Are we doing a "raw" read, or an ECC-based read?
+ *
+ * 2) Are we using block mark swapping or transcription?
+ *
+ * There are four cases, illustrated by the following Karnaugh map:
+ *
+ * | Raw | ECC-based |
+ * -------------+-------------------------+-------------------------+
+ * | Read the conventional | |
+ * | OOB at the end of the | |
+ * Swapping | page and return it. It | |
+ * | contains exactly what | |
+ * | we want. | Read the block mark and |
+ * -------------+-------------------------+ return it in a buffer |
+ * | Read the conventional | full of set bits. |
+ * | OOB at the end of the | |
+ * | page and also the block | |
+ * Transcribing | mark in the metadata. | |
+ * | Copy the block mark | |
+ * | into the first byte of | |
+ * | the OOB. | |
+ * -------------+-------------------------+-------------------------+
+ *
+ * Note that we break rule #4 in the Transcribing/Raw case because we're not
+ * giving an accurate view of the actual, physical bytes in the page (we're
+ * overwriting the block mark). That's OK because it's more important to follow
+ * rule #2.
+ *
+ * It turns out that knowing whether we want an "ECC-based" or "raw" read is not
+ * easy. When reading a page, for example, the NAND Flash MTD code calls our
+ * ecc.read_page or ecc.read_page_raw function. Thus, the fact that MTD wants an
+ * ECC-based or raw view of the page is implicit in which function it calls
+ * (there is a similar pair of ECC-based/raw functions for writing).
+ *
+ * Since MTD assumes the OOB is not covered by ECC, there is no pair of
+ * ECC-based/raw functions for reading or or writing the OOB. The fact that the
+ * caller wants an ECC-based or raw view of the page is not propagated down to
+ * this driver.

+ This option allows you to select a number of media drivers that

+ Most of them don't follow properly the V4L, DVB and/or RC API's,
+ so, they won't likely work fine with the existing applications.
+ That also means that, one fixed, their API's will change to match
+ the existing ones.
+
+ If you wish to work on these drivers, to help improve them, or

-Todo:
- - Fix the loss of some blocks when receiving the video URB's
- - Add a lock at tm6000_read_write_usb() to prevent two simultaneous access to the
- URB control transfers
- - Properly add the locks at tm6000-video
- - Add audio support
- - Add vbi support
- - Add IR support
- - Do several cleanups
- - I think that frame1/frame0 are inverted. This causes a funny effect at the image.
- the fix is trivial, but require some tests
- - My tm6010 devices sometimes insist on stop working. I need to turn them off, removing
- from my machine and wait for a while for it to work again. I'm starting to think that
- it is an overheat issue - is there a workaround that we could do?
- - Sometimes, tm6010 doesn't read eeprom at the proper time (hardware bug). So, the device
- got miss-detected as a "generic" tm6000. This can be really bad if the tuner is the
- Low Power one, as it may result on loading the high power firmware, that could damage
- the device. Maybe we may read eeprom to double check, when the device is marked as "generic"
- - Coding Style fixes
- - sparse cleanups

+ * This is the implementation for the generic read ahead framework.
+ *
+ * To trigger a readahead, btrfs_reada_add must be called. It will start
+ * a read ahead for the given range [start, end) on tree root. The returned
+ * handle can either be used to wait on the readahead to finish
+ * (btrfs_reada_wait), or to send it to the background (btrfs_reada_detach).
+ *
+ * The read ahead works as follows:
+ * On btrfs_reada_add, the root of the tree is inserted into a radix_tree.
+ * reada_start_machine will then search for extents to prefetch and trigger
+ * some reads. When a read finishes for a node, all contained node/leaf
+ * pointers that lie in the given range will also be enqueued. The reads will
+ * be triggered in sequential order, thus giving a big win over a naive
+ * enumeration. It will also make use of multi-device layouts. Each disk
+ * will have its on read pointer and all disks will by utilized in parallel.
+ * Also will no two disks read both sides of a mirror simultaneously, as this
+ * would waste seeking capacity. Instead both disks will read different parts
+ * of the filesystem.
+ * Any number of readaheads can be started in parallel. The read order will be
+ * determined globally, i.e. 2 parallel readaheads will normally finish faster
+ * than the 2 started one after another.

+These module parameters can be specified or modified either during the time of
+module loading or during the runtime by using the interface
+ /proc/module/cifs/parameters/<param>
+
+i.e. echo "value" > /sys/module/cifs/parameters/<param>
+
+1. echo_retries - The number of echo attempts before giving up and

+ means never reconnect.
+
+2. enable_oplocks - Enable or disable oplocks. Oplocks are enabled by default.
+ [Y/y/1]. To disable use any of [N/n/0].

+ * * First comes delayed allocation write for

+ * previous delayed allocated blocks in the
+ * range [8-11], we would reserve 1 cluster
+ * for this write.
+ * * Next comes write for logical blocks 3 to 8.
+ * In this case, we will reserve 2 clusters
+ * (for [0-3] and [4-7]; and not for [8-11] as
+ * that range has a delayed allocated blocks.
+ * Thus total reserved clusters now becomes 3.
+ * * Now, during the delayed allocation writeout
+ * time, we will first write blocks [3-8] and
+ * allocate 3 clusters for writing these
+ * blocks. Also, we would claim all these
+ * three clusters above.
+ * * Now when we come here to writeout the

+ * (and we would claim it since there are no
+ * more delayed allocated blocks in the range
+ * [8-11]. But our reserved cluster count had

+ * Thus, at the step 4 above when we determine
+ * that there are still some unwritten delayed
+ * allocated blocks outside of our current

+ By default Squashfs sets the dev block size (sb_min_blocksize)
+ to 1K or the smallest block size supported by the block device
+ (if larger). This, because blocks are packed together and
+ unaligned in Squashfs, should reduce latency.
+
+ This, however, gives poor performance on MTD NAND devices where
+ the optimal I/O size is 4K (even though the devices can support
+ smaller block sizes).
+
+ Using a 4K device block size may also improve overall I/O
+ performance for some file access patterns (e.g. sequential
+ accesses of files in filesystem order) on all media.
+
+ Setting this option will force Squashfs to use a 4K device block
+ size by default.

+ * There are several things to be aware of that aren't at all obvious:
+ *
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!). In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices: The individual chip on a memory stick. These devices
+ * commonly output 4 and 8 bits each. Grouping several
+ * of these in parallel provides 64 bits which is common
+ * for a memory stick.
+ *
+ * Memory Stick: A printed circuit board that aggregates multiple
+ * memory devices in parallel. This is the atomic
+ * memory component that is purchaseable by Joe consumer
+ * and loaded into a memory socket.
+ *
+ * Socket: A physical connector on the motherboard that accepts
+ * a single memory stick.
+ *
+ * Channel: Set of memory devices on a memory stick that must be
+ * grouped in parallel with one or more additional
+ * channels from other memory sticks. This parallel
+ * grouping of the output from multiple channels are
+ * necessary for the smallest granularity of memory access.
+ * Some memory controllers are capable of single channel -
+ * which means that memory sticks can be loaded
+ * individually. Other memory controllers are only
+ * capable of dual channel - which means that memory
+ * sticks must be loaded as pairs (see "socket set").
+ *
+ * Chip-select row: All of the memory devices that are selected together.
+ * for a single, minimum grain of memory access.
+ * This selects all of the parallel memory devices across
+ * all of the parallel channels. Common chip-select rows
+ * for single channel are 64 bits, for dual channel 128
+ * bits.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
+ * Motherboards commonly drive two chip-select pins to
+ * a memory stick. A single-ranked stick, will occupy
+ * only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently.
+ *
+ * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
+ * A double-sided stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently. "Double-sided"
+ * is irrespective of the memory devices being mounted
+ * on both sides of the memory stick.
+ *
+ * Socket set: All of the memory sticks that are required for
+ * a single memory access or all of the memory sticks
+ * spanned by a chip-select row. A single socket set
+ * has two chip-select rows and if double-sided sticks
+ * are used these will occupy those chip-select rows.
+ *
+ * Bank: This term is avoided because it is unclear when
+ * needing to distinguish between chip-select rows and
+ * socket sets.
+ *
+ * Controller pages:
+ *
+ * Physical pages:
+ *

+ for details. YYERROR is fine as it does not invoke this

+ - If this state is a consistent state with a default action, then
+ the only way this function was invoked is if the default action
+ is an error action. In that case, don't check for expected
+ tokens because there are none.
+ - The only way there can be no lookahead present (in yychar) is if
+ this state is a consistent state with a default action. Thus,
+ detecting the absence of a lookahead is sufficient to determine
+ that there is no unexpected or expected token to report. In that
+ case, just report a simple "syntax error".
+ - Don't assume there isn't a lookahead just because this state is a
+ consistent state with a default action. There might have been a
+ previous inconsistent state, consistent state with a non-default
+ action, or user semantic action that manipulated yychar.
+ - Of course, the expected token list depends on states to have
+ correct lookahead information, and it depends on the parser not
+ to perform extra reductions after fetching a lookahead from the
+ scanner and before detecting a syntax error. Thus, state merging
+ (from LALR or IELR) and default reductions corrupt the expected
+ token list. However, the list is correct for canonical LR with
+ one exception: it will still contain any token that will not be
+ accepted due to an error action in a later state.
