+ * Each clock can have zero, one, or two dividers which change the
+ * output rate of the clock.  Each divider can be either fixed or
+ * variable.  If there are two dividers, they are the "pre-divider"
+ * and the "regular" or "downstream" divider.  If there is only one,
+ * there is no pre-divider.
+ *
+ * A fixed divider is any non-zero (positive) value, and it
+ * indicates how the input rate is affected by the divider.
+ *
+ * The value of a variable divider is maintained in a sub-field of a
+ * 32-bit divider register.  The position of the field in the
+ * register is defined by its offset and width.  The value recorded
+ * in this field is always 1 less than the value it represents.
+ *
+ * In addition, a variable divider can indicate that some subset
+ * of its bits represent a "fractional" part of the divider.  Such
+ * bits comprise the low-order portion of the divider field, and can
+ * be viewed as representing the portion of the divider that lies to
+ * the right of the decimal point.  Most variable dividers have zero
+ * fractional bits.  Variable dividers with non-zero fraction width
+ * still record a value 1 less than the value they represent; the
+ * added 1 does *not* affect the low-order bit in this case, it
+ * affects the bits above the fractional part only.  (Often in this
+ * code a divider field value is distinguished from the value it
+ * represents by referring to the latter as a "divisor".)
+ *
+ * In order to avoid dealing with fractions, divider arithmetic is
+ * performed using "scaled" values.  A scaled value is one that's
+ * been left-shifted by the fractional width of a divider.  Dividing
+ * a scaled value by a scaled divisor produces the desired quotient
+ * without loss of precision and without any other special handling
+ * for fractions.
+ *
+ * The recorded value of a variable divider can be modified.  To
+ * modify either divider (or both), a clock must be enabled (i.e.,
+ * using its gate).  In addition, a trigger register (described
+ * below) must be used to commit the change, and polled to verify

+ * Only the GMAC should use this clock. Altering the clock so that it doesn't

+ * QCOM BAM DMA engine driver

+ * QCOM BAM DMA blocks are distributed amongst a number of the on-chip
+ * peripherals on the MSM 8x74.  The configuration of the channels are dependent
+ * on the way they are hard wired to that specific peripheral.  The peripheral
+ * device tree entries specify the configuration of each channel.
+ *
+ * The DMA controller requires the use of external memory for storage of the
+ * hardware descriptors for each channel.  The descriptor FIFO is accessed as a
+ * circular buffer and operations are managed according to the offset within the
+ * FIFO.  After pipe/channel reset, all of the pipe registers and internal state
+ * are back to defaults.
+ *
+ * During DMA operations, we write descriptors to the FIFO, being careful to
+ * handle wrapping and then write the last FIFO offset to that channel's
+ * P_EVNT_REG register to kick off the transaction.  The P_SW_OFSTS register
+ * indicates the current FIFO offset that is being processed, so there is some
+ * indication of where the hardware is currently working.

+ * This helper doesn't provide a error return value since restoring the old

+ * has successfully set the restored configuration already. Hence this should

+ * configuration is restored in a different order than when userspace set it up)
+ * need to use their own restore logic.

+/**
+ * DOC: Overview
+ *
+ * drm_mm provides a simple range allocator. The drivers are free to use the
+ * resource allocator from the linux core if it suits them, the upside of drm_mm
+ * is that it's in the DRM core. Which means that it's easier to extend for
+ * some of the crazier special purpose needs of gpus.
+ *
+ * The main data struct is &drm_mm, allocations are tracked in &drm_mm_node.
+ * Drivers are free to embed either of them into their own suitable
+ * datastructures. drm_mm itself will not do any allocations of its own, so if
+ * drivers choose not to embed nodes they need to still allocate them
+ * themselves.
+ *
+ * The range allocator also supports reservation of preallocated blocks. This is
+ * useful for taking over initial mode setting configurations from the firmware,
+ * where an object needs to be created which exactly matches the firmware's
+ * scanout target. As long as the range is still free it can be inserted anytime
+ * after the allocator is initialized, which helps with avoiding looped
+ * depencies in the driver load sequence.
+ *
+ * drm_mm maintains a stack of most recently freed holes, which of all
+ * simplistic datastructures seems to be a fairly decent approach to clustering
+ * allocations and avoiding too much fragmentation. This means free space
+ * searches are O(num_holes). Given that all the fancy features drm_mm supports
+ * something better would be fairly complex and since gfx thrashing is a fairly
+ * steep cliff not a real concern. Removing a node again is O(1).
+ *
+ * drm_mm supports a few features: Alignment and range restrictions can be
+ * supplied. Further more every &drm_mm_node has a color value (which is just an
+ * opaqua unsigned long) which in conjunction with a driver callback can be used
+ * to implement sophisticated placement restrictions. The i915 DRM driver uses
+ * this to implement guard pages between incompatible caching domains in the
+ * graphics TT.
+ *
+ * Two behaviors are supported for searching and allocating: bottom-up and top-down.
+ * The default is bottom-up. Top-down allocation can be used if the memory area
+ * has different restrictions, or just to reduce fragmentation.
+ *
+ * Finally iteration helpers to walk all nodes and all holes are provided as are
+ * some basic allocator dumpers for debugging.

+ * efficient when we simply start to select all objects from the tail of an LRU
+ * until there's a suitable hole: Especially for big objects or nodes that

+ * The DRM range allocator supports this use-case through the scanning
+ * interfaces. First a scan operation needs to be initialized with
+ * drm_mm_init_scan() or drm_mm_init_scan_with_range(). The the driver adds
+ * objects to the roaster (probably by walking an LRU list, but this can be
+ * freely implemented) until a suitable hole is found or there's no further
+ * evitable object.
+ *
+ * The the driver must walk through all objects again in exactly the reverse
+ * order to restore the allocator state. Note that while the allocator is used
+ * in the scan mode no other operation is allowed.
+ *
+ * Finally the driver evicts all objects selected in the scan. Adding and
+ * removing an object is O(1), and since freeing a node is also O(1) the overall
+ * complexity is O(scanned_objects). So like the free stack which needs to be
+ * walked before a scan operation even begins this is linear in the number of

+
+/**
+ * DOC: i915 batch buffer command parser
+ *
+ * Motivation:
+ * Certain OpenGL features (e.g. transform feedback, performance monitoring)
+ * require userspace code to submit batches containing commands such as
+ * MI_LOAD_REGISTER_IMM to access various registers. Unfortunately, some
+ * generations of the hardware will noop these commands in "unsecure" batches
+ * (which includes all userspace batches submitted via i915) even though the
+ * commands may be safe and represent the intended programming model of the
+ * device.
+ *
+ * The software command parser is similar in operation to the command parsing
+ * done in hardware for unsecure batches. However, the software parser allows
+ * some operations that would be noop'd by hardware, if the parser determines
+ * the operation is safe, and submits the batch as "secure" to prevent hardware
+ * parsing.
+ *
+ * Threats:
+ * At a high level, the hardware (and software) checks attempt to prevent
+ * granting userspace undue privileges. There are three categories of privilege.
+ *
+ * First, commands which are explicitly defined as privileged or which should
+ * only be used by the kernel driver. The parser generally rejects such
+ * commands, though it may allow some from the drm master process.
+ *
+ * Second, commands which access registers. To support correct/enhanced
+ * userspace functionality, particularly certain OpenGL extensions, the parser
+ * provides a whitelist of registers which userspace may safely access (for both
+ * normal and drm master processes).
+ *
+ * Third, commands which access privileged memory (i.e. GGTT, HWS page, etc).
+ * The parser always rejects such commands.
+ *
+ * The majority of the problematic commands fall in the MI_* range, with only a
+ * few specific commands on each ring (e.g. PIPE_CONTROL and MI_FLUSH_DW).
+ *
+ * Implementation:
+ * Each ring maintains tables of commands and registers which the parser uses in
+ * scanning batch buffers submitted to that ring.
+ *
+ * Since the set of commands that the parser must check for is significantly
+ * smaller than the number of commands supported, the parser tables contain only
+ * those commands required by the parser. This generally works because command
+ * opcode ranges have standard command length encodings. So for commands that
+ * the parser does not need to check, it can easily skip them. This is
+ * implementated via a per-ring length decoding vfunc.
+ *
+ * Unfortunately, there are a number of commands that do not follow the standard
+ * length encoding for their opcode range, primarily amongst the MI_* commands.
+ * To handle this, the parser provides a way to define explicit "skip" entries
+ * in the per-ring command tables.
+ *
+ * Other command table entries map fairly directly to high level categories
+ * mentioned above: rejected, master-only, register whitelist. The parser
+ * implements a number of checks, including the privileged memory checks, via a
+ * general bitmasking mechanism.

 /*
- * This struct tracks the state needed for the Package C8+ feature.
- *
- * Package states C8 and deeper are really deep PC states that can only be
- * reached when all the devices on the system allow it, so even if the graphics
- * device allows PC8+, it doesn't mean the system will actually get to these
- * states.
- *
- * Our driver only allows PC8+ when all the outputs are disabled, the power well
- * is disabled and the GPU is idle. When these conditions are met, we manually
- * do the other conditions: disable the interrupts, clocks and switch LCPLL
- * refclk to Fclk.
- *
- * When we really reach PC8 or deeper states (not just when we allow it) we lose
- * the state of some registers, so when we come back from PC8+ we need to
- * restore this state. We don't get into PC8+ if we're not in RC6, so we don't
- * need to take care of the registers kept by RC6.
+ * This struct helps tracking the state needed for runtime PM, which puts the
+ * device in PCI D3 state. Notice that when this happens, nothing on the
+ * graphics device works, even register access, so we don't get interrupts nor
+ * anything else.
  *
- * The interrupt disabling is part of the requirements. We can only leave the
- * PCH HPD interrupts enabled. If we're in PC8+ and we get another interrupt we
- * can lock the machine.
+ * Every piece of our code that needs to actually touch the hardware needs to
+ * either call intel_runtime_pm_get or call intel_display_power_get with the
+ * appropriate power domain.
  *
- * Ideally every piece of our code that needs PC8+ disabled would call
- * hsw_disable_package_c8, which would increment disable_count and prevent the
- * system from reaching PC8+. But we don't have a symmetric way to do this for
- * everything, so we have the requirements_met and gpu_idle variables. When we
- * switch requirements_met or gpu_idle to true we decrease disable_count, and
- * increase it in the opposite case. The requirements_met variable is true when
- * all the CRTCs, encoders and the power well are disabled. The gpu_idle
- * variable is true when the GPU is idle.
- *
- * In addition to everything, we only actually enable PC8+ if disable_count
- * stays at zero for at least some seconds. This is implemented with the
- * enable_work variable. We do this so we don't enable/disable PC8 dozens of
- * consecutive times when all screens are disabled and some background app
- * queries the state of our connectors, or we have some application constantly
- * waking up to use the GPU. Only after the enable_work function actually
- * enables PC8+ the "enable" variable will become true, which means that it can
- * be false even if disable_count is 0.
+ * Our driver uses the autosuspend delay feature, which means we'll only really
+ * suspend if we stay with zero refcount for a certain amount of time. The
+ * default value is currently very conservative (see intel_init_runtime_pm), but
+ * it can be changed with the standard runtime PM files from sysfs.
  *
  * The irqs_disabled variable becomes true exactly after we disable the IRQs and
  * goes back to false exactly before we reenable the IRQs. We use this variable

+ * Package states C8 and deeper are really deep PC states that can only be

+ *
+ * The requirements for PC8+ are that all the outputs are disabled, the power
+ * well is disabled and most interrupts are disabled, and these are also
+ * requirements for runtime PM. When these conditions are met, we manually do
+ * the other conditions: disable the interrupts, clocks and switch LCPLL refclk
+ * to Fclk. If we're in PC8+ and we get an non-hotplug interrupt, we can hard
+ * hang the machine.
+ *
+ * When we really reach PC8 or deeper states (not just when we allow it) we lose
+ * the state of some registers, so when we come back from PC8+ we need to
+ * restore this state. We don't get into PC8+ if we're not in RC6, so we don't
+ * need to take care of the registers kept by RC6. Notice that this happens even

+ * GPUVM
+ * GPUVM is similar to the legacy gart on older asics, however

+ * for the entire GPU, there are multiple VM page tables active
+ * at any given time.  The VM page tables can contain a mix
+ * vram pages and system memory pages and system memory pages
+ * can be mapped as snooped (cached system pages) or unsnooped
+ * (uncached system pages).
+ * Each VM has an ID associated with it and there is a page table
+ * associated with each VMID.  When execting a command buffer,
+ * the kernel tells the the ring what VMID to use for that command
+ * buffer.  VMIDs are allocated dynamically as commands are submitted.
+ * The userspace drivers maintain their own address space and the kernel
+ * sets up their pages tables accordingly when they submit their
+ * command buffers and a VMID is assigned.
+ * Cayman/Trinity support up to 8 active VMs at any given time;
+ * SI supports 16.

+* (3) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=1
+*
+* The default setting will be (3) both long and short.
+* The default setting will need no compile switches.

+* Comments about DRXDAP_MAX_WCHUNKSIZE in single or multi master mode and
+* in combination with short and long addressing format. All text below
+* assumes long addressing format. The table also includes information
+* for short ADDRessing format.
+*
+* In single master mode, data can be written by sending the register address
+* first, then two or four bytes of data in the next packet.
+* Because the device address plus a register address equals five bytes,
+* the mimimum chunk size must be five.
+* If ten-bit I2C device addresses are used, the minimum chunk size must be six,
+* because the I2C device address will then occupy two bytes when writing.
+*
+* Data in single master mode is transferred as follows:
+* <S> <devW>  a0  a1  a2  a3  <P>
+* <S> <devW>  d0  d1 [d2  d3] <P>
+* ..
+* or
+* ..
+* <S> <devW>  a0  a1  a2  a3  <P>
+* <S> <devR> --- <P>
+*
+* In multi-master mode, the data must immediately follow the address (an I2C
+* stop resets the internal address), and hence the minimum chunk size is
+* 1 <I2C address> + 4 (register address) + 2 (data to send) = 7 bytes (8 if
+* 10-bit I2C device addresses are used).

+   Implementation notes.
+
+   NTSC/FM AGCs
+
+      Four AGCs are used for NTSC:
+      (1) RF (used to attenuate the input signal in case of to much power)
+      (2) IF (used to attenuate the input signal in case of to much power)
+      (3) Video AGC (used to amplify the output signal in case input to low)
+      (4) SIF AGC (used to amplify the output signal in case input to low)
+
+      Video AGC is coupled to RF and IF. SIF AGC is not coupled. It is assumed
+      that the coupling between Video AGC and the RF and IF AGCs also works in
+      favor of the SIF AGC.
+
+      Three AGCs are used for FM:
+      (1) RF (used to attenuate the input signal in case of to much power)
+      (2) IF (used to attenuate the input signal in case of to much power)
+      (3) SIF AGC (used to amplify the output signal in case input to low)
+
+      The SIF AGC is now coupled to the RF/IF AGCs.
+      The SIF AGC is needed for both SIF ouput and the internal SIF signal to
+      the AUD block.
+
+      RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of
+      the ATV block. The AGC control algorithms are all implemented in
+      microcode.
+
+   ATV SETTINGS
+
+      (Shadow settings will not be used for now, they will be implemented
+       later on because of the schedule)
+
+      Several HW/SCU "settings" can be used for ATV. The standard selection
+      will reset most of these settings. To avoid that the end user apllication
+      has to perform these settings each time the ATV or FM standards is
+      selected the driver will shadow these settings. This enables the end user
+      to perform the settings only once after a drx_open(). The driver must
+      write the shadow settings to HW/SCU incase:
+	 ( setstandard FM/ATV) ||
+	 ( settings have changed && FM/ATV standard is active)
+      The shadow settings will be stored in the device specific data container.
+      A set of flags will be defined to flag changes in shadow settings.
+      A routine will be implemented to write all changed shadow settings to
+      HW/SCU.
+
+      The "settings" will consist of: AGC settings, filter settings etc.
+
+      Disadvantage of use of shadow settings:
+      Direct changes in HW/SCU registers will not be reflected in the
+      shadow settings and these changes will be overwritten during a next
+      update. This can happen during evaluation. This will not be a problem
+      for normal customer usage.

-	  If you say Y here, the MMC layer will assume that all cards

-	  normal behaviour is to remove them at suspend and
-	  redetecting them at resume. Breaking this assumption will
-	  in most cases result in data corruption.
-
-	  This option is usually just for embedded systems which use
-	  a MMC/SD card for rootfs. Most people should say N here.

+	   This option enables read-only UBI block devices support. UBI block
+	   devices will be layered on top of UBI volumes, which means that the
+	   UBI driver will transparently handle things like bad eraseblocks and
+	   bit-flips. You can put any block-oriented file system on top of UBI
+	   volumes in read-only mode (e.g., ext4), but it is probably most
+	   practical for read-only file systems, like squashfs.
+
+	   When selected, this feature will be built in the UBI driver.

+ * Read-only block devices on top of UBI volumes

+ * A simple implementation to allow a block device to be layered on top of a
+ * UBI volume. The implementation is provided by creating a static 1-to-1
+ * mapping between the block device and the UBI volume.
+ *
+ * The addressed byte is obtained from the addressed block sector, which is
+ * mapped linearly into the corresponding LEB:
+ *
+ *   LEB number = addressed byte / LEB size
+ *
+ * This feature is compiled in the UBI core, and adds a 'block' parameter
+ * to allow early creation of block devices on top of UBI volumes. Runtime
+ * block creation/removal for UBI volumes is provided through two UBI ioctls:
+ * UBI_IOCVOLCRBLK and UBI_IOCVOLRMBLK.

+ * Macros are used to shorten the table lines and make this table human

+ * We store the PTYPE in the top byte of the bit field - this is just so that

+ * ELSE IF i40evf_ptype_lookup[ptype].outer_ip == I40E_RX_PTYPE_OUTER_IP

+/* There are 3 ways the host can communicate with the trf7970a:
+ * parallel mode, SPI with Slave Select (SS) mode, and SPI without
+ * SS mode.  The driver only supports the two SPI modes.
+ *
+ * The trf7970a is very timing sensitive and the VIN, EN2, and EN
+ * pins must asserted in that order and with specific delays in between.
+ * The delays used in the driver were provided by TI and have been
+ * confirmed to work with this driver.
+ *
+ * Timeouts are implemented using the delayed workqueue kernel facility.
+ * Timeouts are required so things don't hang when there is no response
+ * from the trf7970a (or tag).  Using this mechanism creates a race with
+ * interrupts, however.  That is, an interrupt and a timeout could occur
+ * closely enough together that one is blocked by the mutex while the other
+ * executes.  When the timeout handler executes first and blocks the
+ * interrupt handler, it will eventually set the state to IDLE so the
+ * interrupt handler will check the state and exit with no harm done.
+ * When the interrupt handler executes first and blocks the timeout handler,
+ * the cancel_delayed_work() call will know that it didn't cancel the
+ * work item (i.e., timeout) and will return zero.  That return code is
+ * used by the timer handler to indicate that it should ignore the timeout
+ * once its unblocked.
+ *
+ * Aborting an active command isn't as simple as it seems because the only
+ * way to abort a command that's already been sent to the tag is so turn
+ * off power to the tag.  If we do that, though, we'd have to go through
+ * the entire anticollision procedure again but the digital layer doesn't
+ * support that.  So, if an abort is received before trf7970a_in_send_cmd()
+ * has sent the command to the tag, it simply returns -ECANCELED.  If the
+ * command has already been sent to the tag, then the driver continues
+ * normally and recieves the response data (or error) but just before
+ * sending the data upstream, it frees the rx_skb and sends -ECANCELED
+ * upstream instead.  If the command failed, that error will be sent
+ * upstream.
+ *
+ * When recieving data from a tag and the interrupt status register has
+ * only the SRX bit set, it means that all of the data has been received
+ * (once what's in the fifo has been read).  However, depending on timing
+ * an interrupt status with only the SRX bit set may not be recived.  In
+ * those cases, the timeout mechanism is used to wait 5 ms in case more
+ * data arrives.  After 5 ms, it is assumed that all of the data has been
+ * received and the accumulated rx data is sent upstream.  The
+ * 'TRF7970A_ST_WAIT_FOR_RX_DATA_CONT' state is used for this purpose
+ * (i.e., it indicates that some data has been received but we're not sure
+ * if there is more coming so a timeout in this state means all data has
+ * been received and there isn't an error).  The delay is 5 ms since delays
+ * over 2 ms have been observed during testing (a little extra just in case).
+ *
+ * Type 2 write and sector select commands respond with a 4-bit ACK or NACK.
+ * Having only 4 bits in the FIFO won't normally generate an interrupt so
+ * driver enables the '4_bit_RX' bit of the Special Functions register 1
+ * to cause an interrupt in that case.  Leaving that bit for a read command
+ * messes up the data returned so it is only enabled when the framing is
+ * 'NFC_DIGITAL_FRAMING_NFCA_T2T' and the command is not a read command.
+ * Unfortunately, that means that the driver has to peek into tx frames
+ * when the framing is 'NFC_DIGITAL_FRAMING_NFCA_T2T'.  This is done by
+ * the trf7970a_per_cmd_config() routine.
+ *
+ * ISO/IEC 15693 frames specify whether to use single or double sub-carrier
+ * frequencies and whether to use low or high data rates in the flags byte
+ * of the frame.  This means that the driver has to peek at all 15693 frames
+ * to determine what speed to set the communication to.  In addition, write
+ * and lock commands use the OPTION flag to indicate that an EOF must be
+ * sent to the tag before it will send its response.  So the driver has to
+ * examine all frames for that reason too.
+ *
+ * It is unclear how long to wait before sending the EOF.  According to the
+ * Note under Table 1-1 in section 1.6 of
+ * http://www.ti.com/lit/ug/scbu011/scbu011.pdf, that wait should be at least
+ * 10 ms for TI Tag-it HF-I tags; however testing has shown that is not long
+ * enough.  For this reason, the driver waits 20 ms which seems to work
+ * reliably.

- * - split USB ADC interface and RF tuner to own drivers (msi2500 and msi001)
- * - move controls to V4L2 API
- * - use libv4l2 for stream format conversions
- * - gr-kernel: switch to v4l2_mmap (current read eats a lot of cpu)
- * - SDRSharp support

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts.  The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames.  With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.

+- find and remove code valid only for 5 HGz. Many of the obvious

+- find and remove any code for other chips that is left over
+- convert any remaining unusual variable types
+- find codes that can use %pM and %Nph formatting
+- checkpatch.pl fixes - most of the remaining ones are lines too long. Many
+  of them will require refactoring
+- merge Realtek's bugfixes and new features into the driver
+- switch to use MAC80211
+
+Please send any patches to Greg Kroah-Hartman <gregkh@linux.com>,

+	 * resulted in a couple unusual behaviors.  First, if a range is not
+	 * able to be unmapped, ex. a set of 4k pages that was mapped as a
+	 * 2M hugepage into the IOMMU, the unmap ioctl returns success but with
+	 * a zero sized unmap.  Also, if an unmap request overlaps the first

+	 * This also returns success and the returned unmap size reflects the
+	 * actual size unmapped.

+	 * We attempt to maintain compatibility with this "v1" interface, but

+	 * request offset from the beginning of the original mapping will
+	 * return success with zero sized unmap.  And an unmap request covering
+	 * the first iova of mapping will unmap the entire range.
+	 *
+	 * The v2 version of this interface intends to be more deterministic.
+	 * Unmap requests must fully cover previous mappings.  Multiple
+	 * mappings may still be unmaped by specifying large ranges, but there
+	 * must not be any previous mappings bisected by the range.  An error

-	---help---
-	  The frame buffer device provides an abstraction for the graphics
-	  hardware. It represents the frame buffer of some video hardware and
-	  allows application software to access the graphics hardware through
-	  a well-defined interface, so the software doesn't need to know
-	  anything about the low-level (hardware register) stuff.
-
-	  Frame buffer devices work identically across the different
-	  architectures supported by Linux and make the implementation of
-	  application programs easier and more portable; at this point, an X
-	  server exists which uses the frame buffer device exclusively.
-	  On several non-X86 architectures, the frame buffer device is the
-	  only way to use the graphics hardware.
-
-	  The device is accessed through special device nodes, usually located
-	  in the /dev directory, i.e. /dev/fb*.
-
-	  You need an utility program called fbset to make full use of frame
-	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-	  and the Framebuffer-HOWTO at
-	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
-	  information.
-
-	  Say Y here and to the driver for your graphics board below if you
-	  are compiling a kernel for a non-x86 architecture.
-
-	  If you are compiling for the x86 architecture, you can say Y if you
-	  want to play with it, but it is not essential. Please note that
-	  running graphical applications that directly touch the hardware
-	  (e.g. an accelerated X server) and that are not frame buffer
-	  device-aware may cause unexpected results. If unsure, say N.

-          set of values), you'll be able to use any combination of horizontal 
-	  and vertical resolutions, and vertical refresh rates without having
-	  to specify your own timing parameters.  This is especially useful
-	  to maximize the performance of an aging display, or if you just 
-          have a display with nonstandard dimensions. A VESA compliant 
-	  monitor is recommended, but can still work with non-compliant ones.

+	tristate "Support for frame buffer devices"
+	---help---
+	  The frame buffer device provides an abstraction for the graphics
+	  hardware. It represents the frame buffer of some video hardware and
+	  allows application software to access the graphics hardware through
+	  a well-defined interface, so the software doesn't need to know
+	  anything about the low-level (hardware register) stuff.
+
+	  Frame buffer devices work identically across the different
+	  architectures supported by Linux and make the implementation of
+	  application programs easier and more portable; at this point, an X
+	  server exists which uses the frame buffer device exclusively.
+	  On several non-X86 architectures, the frame buffer device is the
+	  only way to use the graphics hardware.
+
+	  The device is accessed through special device nodes, usually located
+	  in the /dev directory, i.e. /dev/fb*.
+
+	  You need an utility program called fbset to make full use of frame
+	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
+	  and the Framebuffer-HOWTO at
+	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
+	  information.
+
+	  Say Y here and to the driver for your graphics board below if you
+	  are compiling a kernel for a non-x86 architecture.
+
+	  If you are compiling for the x86 architecture, you can say Y if you
+	  want to play with it, but it is not essential. Please note that
+	  running graphical applications that directly touch the hardware
+	  (e.g. an accelerated X server) and that are not frame buffer
+	  device-aware may cause unexpected results. If unsure, say N.

+	 nvidiafb, i810fb or savagefb.
+
+	 In general, choosing Y for this option is safe.  If you
