+ * Renaming devices is racy at many levels, symlinks and other stuff are not

+ * connect the event to the old and new device. Device nodes are not renamed at
+ * all, there isn't even support for that in the kernel now.
+ *
+ * In the meantime, during renaming, your target name might be taken by another
+ * driver, creating conflicts. Or the old name is taken directly after you
+ * renamed it -- then you get events for the same DEVPATH, before you even see
+ * the "move" event. It's just a mess, and nothing new should ever rely on
+ * kernel device renaming. Besides that, it's not even implemented now for
+ * other things than (driver-core wise very simple) network devices.
+ *
+ * We are currently about to change network renaming in udev to completely
+ * disallow renaming of devices in the same namespace as the kernel uses,
+ * because we can't solve the problems properly, that arise with swapping names
+ * of multiple interfaces without races. Means, renaming of eth[0-9]* will only
+ * be allowed to some other name than eth[0-9]*, for the aforementioned
+ * reasons.
+ *
+ * Make up a "real" name in the driver before you register anything, or add
+ * some other attributes for userspace to find the device, or use udev to add
+ * symlinks -- but never rename kernel devices later, it's a complete mess. We

-	default y
-	---help---
-	  If you say Y here, you will get support for terminal devices with
-	  display and keyboard devices. These are called "virtual" because you
-	  can run several virtual terminals (also called virtual consoles) on
-	  one physical terminal. This is rather useful, for example one
-	  virtual terminal can collect system messages and warnings, another
-	  one can be used for a text-mode user session, and a third could run
-	  an X session, all in parallel. Switching between virtual terminals
-	  is done with certain key combinations, usually Alt-<function key>.
-
-	  The setterm command ("man setterm") can be used to change the
-	  properties (such as colors or beeping) of a virtual terminal. The
-	  man page console_codes(4) ("man console_codes") contains the special
-	  character sequences that can be used to change those properties
-	  directly. The fonts used on virtual terminals can be changed with
-	  the setfont ("man setfont") command and the key bindings are defined
-	  with the loadkeys ("man loadkeys") command.
-
-	  You need at least one virtual terminal device in order to make use
-	  of your keyboard and monitor. Therefore, only people configuring an
-	  embedded system would want to say N here in order to save some
-	  memory; the only way to log into such a system is then via a serial

-	  answer Y here, a virtual terminal (the device used to interact with
-	  a physical terminal) can be used as system console. This is the most
-	  common mode of operations, so you should say Y here unless you want
-	  the kernel messages be output only to a serial port (in which case
-	  you should say Y to "Console on serial port", below).
-
-	  If you do say Y here, by default the currently visible virtual
-	  terminal (/dev/tty0) will be used as system console. You can change
-	  that with a kernel command line option such as "console=tty3" which
-	  would use the third virtual terminal as system console. (Try "man
-	  bootparam" or see the documentation of your boot loader (lilo or

-         drivers may be enabled, such as the framebuffer console. If more than

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

-	  terminal is then made available to the process and the pseudo
-	  terminal slave can be accessed as /dev/pts/<number>. What was
-	  traditionally /dev/ttyp2 will then be /dev/pts/2, for example.

+ * converters such as CP1800, CP2000AC, CP2000DC, CP2100DC, and others.
+ *
+ * The devices are nominally PMBus compliant. However, most standard PMBus
+ * commands are not supported. Specifically, all hardware monitoring and
+ * status reporting commands are non-standard. For this reason, a standard
+ * PMBus driver can not be used.
+ *
+ * All Lineage CPL devices have a built-in I2C bus master selector (PCA9541).
+ * To ensure device access, this driver should only be used as client driver
+ * to the pca9541 I2C master selector driver.

+ * @pads: Array of 'num_pads' pads.

+ * The total number of pads is an intrinsic property of entities known by the

+ *
+ * For those reasons the links array can be preallocated based on the entity
+ * driver guess and will be reallocated later if extra links need to be
+ * created.
+ *
+ * This function allocates a links array with enough space to hold at least
+ * 'num_pads' + 'extra_links' elements. The media_entity::max_links field will
+ * be set to the number of allocated elements.

+ * The pads array is managed by the entity driver and passed to

+ * The resizer uses a polyphase sample rate converter. The upsampling filter

+ * computation depends on the number of phases, we need to compute a first
+ * approximation and then refine it.
+ *
+ * The input/output/ratio relationship is given by the OMAP34xx TRM:
+ *
+ * - 8-phase, 4-tap mode (RSZ = 64 ~ 512)
+ *	iw = (32 * sph + (ow - 1) * hrsz + 16) >> 8 + 7
+ *	ih = (32 * spv + (oh - 1) * vrsz + 16) >> 8 + 4
+ * - 4-phase, 7-tap mode (RSZ = 513 ~ 1024)
+ *	iw = (64 * sph + (ow - 1) * hrsz + 32) >> 8 + 7
+ *	ih = (64 * spv + (oh - 1) * vrsz + 32) >> 8 + 7
+ *
+ * iw and ih are the input width and height after cropping. Those equations need
+ * to be satisfied exactly for the resizer to work correctly.
+ *
+ * Reverting the equations, we can compute the resizing ratios with
+ *
+ * - 8-phase, 4-tap mode
+ *	hrsz = ((iw - 7) * 256 - 16 - 32 * sph) / (ow - 1)
+ *	vrsz = ((ih - 4) * 256 - 16 - 32 * spv) / (oh - 1)

+ *	vrsz = ((ih - 7) * 256 - 32 - 64 * spv) / (oh - 1)
+ *
+ * The ratios are integer values, and must be rounded down to ensure that the
+ * cropped input size is not bigger than the uncropped input size. As the ratio
+ * in 7-tap mode is always smaller than the ratio in 4-tap mode, we can use the
+ * 7-tap mode equations to compute a ratio approximation.
+ *
+ * We first clamp the output size according to the hardware capabilitie to avoid
+ * auto-cropping the input more than required to satisfy the TRM equations. The
+ * minimum output size is achieved with a scaling factor of 1024. It is thus
+ * computed using the 7-tap equations.
+ *
+ *	min ow = ((iw - 7) * 256 - 32 - 64 * sph) / 1024 + 1
+ *	min oh = ((ih - 7) * 256 - 32 - 64 * spv) / 1024 + 1
+ *
+ * Similarly, the maximum output size is achieved with a scaling factor of 64

+ * Stream management
+ *
+ * Every ISP pipeline has a single input and a single output. The input can be
+ * either a sensor or a video node. The output is always a video node.
+ *
+ * As every pipeline has an output video node, the ISP video objects at the
+ * pipeline output stores the pipeline state. It tracks the streaming state of
+ * both the input and output, as well as the availability of buffers.
+ *
+ * In sensor-to-memory mode, frames are always available at the pipeline input.
+ * Starting the sensor usually requires I2C transfers and must be done in
+ * interruptible context. The pipeline is started and stopped synchronously
+ * to the stream on/off commands. All modules in the pipeline will get their
+ * subdev set stream handler called. The module at the end of the pipeline must
+ * delay starting the hardware until buffers are available at its output.
+ *
+ * In memory-to-memory mode, starting/stopping the stream requires
+ * synchronization between the input and output. ISP modules can't be stopped
+ * in the middle of a frame, and at least some of the modules seem to become
+ * busy as soon as they're started, even if they don't receive a frame start
+ * event. For that reason frames need to be processed in single-shot mode. The
+ * driver needs to wait until a frame is completely processed and written to
+ * memory before restarting the pipeline for the next frame. Pipelined
+ * processing might be possible but requires more testing.
+ *
+ * Stream start must be delayed until buffers are available at both the input
+ * and output. The pipeline must be started in the videobuf queue callback with
+ * the buffers queue spinlock held. The modules subdev set stream operation must
+ * not sleep.

  *
+ * About corruptions
+ * ~~~~~~~~~~~~~~~~~
+ *
+ * UBI protects EC and VID headers with CRC-32 checksums, so it can detect
+ * whether the headers are corrupted or not. Sometimes UBI also protects the
+ * data with CRC-32, e.g., when it executes the atomic LEB change operation, or
+ * when it moves the contents of a PEB for wear-leveling purposes.
+ *
  * UBI tries to distinguish between 2 types of corruptions.
- * 1. Corruptions caused by power cuts. These are harmless and expected
- *    corruptions and UBI tries to handle them gracefully, without printing too
- *    many warnings and error messages. The idea is that we do not lose
- *    important data in these case - we may lose only the data which was being
- *    written to the media just before the power cut happened, and the upper
- *    layers (e.g., UBIFS) are supposed to handle these situations. UBI puts
- *    these PEBs to the head of the @erase list and they are scheduled for
- *    erasure.
+ *
+ * 1. Corruptions caused by power cuts. These are expected corruptions and UBI

+ * error messages. The idea is that we do not lose important data in these case
+ * - we may lose only the data which was being written to the media just before
+ * the power cut happened, and the upper layers (e.g., UBIFS) are supposed to
+ * handle such data losses (e.g., by using the FS journal).
+ *
+ * When UBI detects a corruption (CRC-32 mismatch) in a PEB, and it looks like
+ * the reason is a power cut, UBI puts this PEB to the @erase list, and all
+ * PEBs in the @erase list are scheduled for erasure later.
  *
  * 2. Unexpected corruptions which are not caused by power cuts. During
- *    scanning, such PEBs are put to the @corr list and UBI preserves them.
- *    Obviously, this lessens the amount of available PEBs, and if at some
- *    point UBI runs out of free PEBs, it switches to R/O mode. UBI also loudly
- *    informs about such PEBs every time the MTD device is attached.

  *
  * However, it is difficult to reliably distinguish between these types of
- * corruptions and UBI's strategy is as follows. UBI assumes (2.) if the VID
- * header is corrupted and the data area does not contain all 0xFFs, and there
- * were not bit-flips or integrity errors while reading the data area. Otherwise
- * UBI assumes (1.). The assumptions are:
- *   o if the data area contains only 0xFFs, there is no data, and it is safe
- *     to just erase this PEB.
- *   o if the data area has bit-flips and data integrity errors (ECC errors on
+ * corruptions and UBI's strategy is as follows. UBI assumes corruption type 2
+ * if the VID header is corrupted and the data area does not contain all 0xFFs,
+ * and there were no bit-flips or integrity errors while reading the data area.
+ * Otherwise UBI assumes corruption type 1. So the decision criteria are as
+ * follows.
+ *   o If the data area contains only 0xFFs, there is no data, and it is safe
+ *     to just erase this PEB - this is corruption type 1.
+ *   o If the data area has bit-flips or data integrity errors (ECC errors on
  *     NAND), it is probably a PEB which was being erased when power cut
- *     happened.
+ *     happened, so this is corruption type 1. However, this is just a guess,
+ *     which might be wrong.
+ *   o Otherwise this it corruption type 2.

+ *
+ * For now, the actual "head" pointer points at NET_SKB_PAD bytes of

- *
- *	Tigran Aivazian <tigran@sco.com>:	TLan_PciProbe() now uses
- *						new PCI BIOS interface.
- *	Alan Cox	<alan@lxorguk.ukuu.org.uk>:
- *						Fixed the out of memory
- *						handling.
- *
- *	Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
- *
- *	v1.1 Dec 20, 1999    - Removed linux version checking
- *			       Patch from Tigran Aivazian.
- *			     - v1.1 includes Alan's SMP updates.
- *			     - We still have problems on SMP though,
- *			       but I'm looking into that.
- *
- *	v1.2 Jan 02, 2000    - Hopefully fixed the SMP deadlock.
- *			     - Removed dependency of HZ being 100.
- *			     - We now allow higher priority timers to
- *			       overwrite timers like TLAN_TIMER_ACTIVITY
- *			       Patch from John Cagle <john.cagle@compaq.com>.
- *			     - Fixed a few compiler warnings.
- *
- *	v1.3 Feb 04, 2000    - Fixed the remaining HZ issues.
- *			     - Removed call to pci_present().
- *			     - Removed SA_INTERRUPT flag from irq handler.
- *			     - Added __init and __initdata to reduce resisdent
- *			       code size.
- *			     - Driver now uses module_init/module_exit.
- *			     - Rewrote init_module and tlan_probe to
- *			       share a lot more code. We now use tlan_probe
- *			       with builtin and module driver.
- *			     - Driver ported to new net API.
- *			     - tlan.txt has been reworked to reflect current
- *			       driver (almost)
- *			     - Other minor stuff
- *
- *	v1.4 Feb 10, 2000    - Updated with more changes required after Dave's
- *	                       network cleanup in 2.3.43pre7 (Tigran & myself)
- *	                     - Minor stuff.
- *
- *	v1.5 March 22, 2000  - Fixed another timer bug that would hang the driver
- *			       if no cable/link were present.
- *			     - Cosmetic changes.
- *			     - TODO: Port completely to new PCI/DMA API
- *			     	     Auto-Neg fallback.
- *
- * 	v1.6 April 04, 2000  - Fixed driver support for kernel-parameters. Haven't
- * 			       tested it though, as the kernel support is currently
- * 			       broken (2.3.99p4p3).
- * 			     - Updated tlan.txt accordingly.
- * 			     - Adjusted minimum/maximum frame length.
- * 			     - There is now a TLAN website up at
- * 			       http://hp.sourceforge.net/ 
- *
- * 	v1.7 April 07, 2000  - Started to implement custom ioctls. Driver now
- * 			       reports PHY information when used with Donald
- * 			       Beckers userspace MII diagnostics utility.
- *
- * 	v1.8 April 23, 2000  - Fixed support for forced speed/duplex settings.
- * 			     - Added link information to Auto-Neg and forced
- * 			       modes. When NIC operates with auto-neg the driver
- * 			       will report Link speed & duplex modes as well as
- * 			       link partner abilities. When forced link is used,
- * 			       the driver will report status of the established
- * 			       link.
- * 			       Please read tlan.txt for additional information.
- * 			     - Removed call to check_region(), and used
- * 			       return value of request_region() instead.
- *
- *	v1.8a May 28, 2000   - Minor updates.
- *
- *	v1.9 July 25, 2000   - Fixed a few remaining Full-Duplex issues.
- *	                     - Updated with timer fixes from Andrew Morton.
- *	                     - Fixed module race in TLan_Open.
- *	                     - Added routine to monitor PHY status.
- *	                     - Added activity led support for Proliant devices.
- *
- *	v1.10 Aug 30, 2000   - Added support for EISA based tlan controllers
- *			       like the Compaq NetFlex3/E.
- *			     - Rewrote tlan_probe to better handle multiple
- *			       bus probes. Probing and device setup is now
- *			       done through TLan_Probe and TLan_init_one. Actual
- *			       hardware probe is done with kernel API and
- *			       TLan_EisaProbe.
- *			     - Adjusted debug information for probing.
- *			     - Fixed bug that would cause general debug information
- *			       to be printed after driver removal.
- *			     - Added transmit timeout handling.
- *			     - Fixed OOM return values in tlan_probe.
- *			     - Fixed possible mem leak in tlan_exit
- *			       (now tlan_remove_one).
- *			     - Fixed timer bug in TLan_phyMonitor.
- *			     - This driver version is alpha quality, please
- *			       send me any bug issues you may encounter.
- *
- *	v1.11 Aug 31, 2000   - Do not try to register irq 0 if no irq line was
- *			       set for EISA cards.
- *			     - Added support for NetFlex3/E with nibble-rate
- *			       10Base-T PHY. This is untestet as I haven't got
- *			       one of these cards.
- *			     - Fixed timer being added twice.
- *			     - Disabled PhyMonitoring by default as this is
- *			       work in progress. Define MONITOR to enable it.
- *			     - Now we don't display link info with PHYs that
- *			       doesn't support it (level1).
- *			     - Incresed tx_timeout beacuse of auto-neg.
- *			     - Adjusted timers for forced speeds.
- *
- *	v1.12 Oct 12, 2000   - Minor fixes (memleak, init, etc.)
- *
- * 	v1.13 Nov 28, 2000   - Stop flooding console with auto-neg issues
- * 			       when link can't be established.
- *			     - Added the bbuf option as a kernel parameter.
- *			     - Fixed ioaddr probe bug.
- *			     - Fixed stupid deadlock with MII interrupts.
- *			     - Added support for speed/duplex selection with
- *			       multiple nics.
- *			     - Added partly fix for TX Channel lockup with
- *			       TLAN v1.0 silicon. This needs to be investigated
- *			       further.
- *
- * 	v1.14 Dec 16, 2000   - Added support for servicing multiple frames per.
- * 			       interrupt. Thanks goes to
- * 			       Adam Keys <adam@ti.com>
- * 			       Denis Beaudoin <dbeaudoin@ti.com>
- * 			       for providing the patch.
- * 			     - Fixed auto-neg output when using multiple
- * 			       adapters.
- * 			     - Converted to use new taskq interface.
- *
- * 	v1.14a Jan 6, 2001   - Minor adjustments (spinlocks, etc.)
- *
- *	Samuel Chessman <chessman@tux.org> New Maintainer!
- *
- *	v1.15 Apr 4, 2002    - Correct operation when aui=1 to be
- *	                       10T half duplex no loopback
- *	                       Thanks to Gunnar Eikman
- *
- *	Sakari Ailus <sakari.ailus@iki.fi>:
- *
- *	v1.15a Dec 15 2008   - Remove bbuf support, it doesn't work anyway.

+ *
+ *
+ * FILLING THE RATE TABLE
+ *
+ * Given a particular initial rate and mode, as determined by the rate
+ * scaling algorithm described below, the Linux driver uses the following
+ * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
+ * Link Quality command:
+ *
+ *
+ * 1)  If using High-throughput (HT) (SISO or MIMO) initial rate:
+ *     a) Use this same initial rate for first 3 entries.
+ *     b) Find next lower available rate using same mode (SISO or MIMO),
+ *        use for next 3 entries.  If no lower rate available, switch to
+ *        legacy mode (no HT40 channel, no MIMO, no short guard interval).
+ *     c) If using MIMO, set command's mimo_delimiter to number of entries
+ *        using MIMO (3 or 6).
+ *     d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
+ *        no MIMO, no short guard interval), at the next lower bit rate
+ *        (e.g. if second HT bit rate was 54, try 48 legacy), and follow
+ *        legacy procedure for remaining table entries.
+ *
+ * 2)  If using legacy initial rate:
+ *     a) Use the initial rate for only one entry.
+ *     b) For each following entry, reduce the rate to next lower available
+ *        rate, until reaching the lowest available rate.
+ *     c) When reducing rate, also switch antenna selection.
+ *     d) Once lowest available rate is reached, repeat this rate until
+ *        rate table is filled (16 entries), switching antenna each entry.
+ *
+ *
+ * ACCUMULATING HISTORY
+ *
+ * The rate scaling algorithm for 4965 devices, as implemented in Linux driver,
+ * uses two sets of frame Tx success history:  One for the current/active
+ * modulation mode, and one for a speculative/search mode that is being
+ * attempted. If the speculative mode turns out to be more effective (i.e.
+ * actual transfer rate is better), then the driver continues to use the
+ * speculative mode as the new current active mode.
+ *
+ * Each history set contains, separately for each possible rate, data for a
+ * sliding window of the 62 most recent tx attempts at that rate.  The data
+ * includes a shifting bitmap of success(1)/failure(0), and sums of successful
+ * and attempted frames, from which the driver can additionally calculate a
+ * success ratio (success / attempted) and number of failures
+ * (attempted - success), and control the size of the window (attempted).
+ * The driver uses the bit map to remove successes from the success sum, as
+ * the oldest tx attempts fall out of the window.
+ *
+ * When the 4965 device makes multiple tx attempts for a given frame, each
+ * attempt might be at a different rate, and have different modulation
+ * characteristics (e.g. antenna, fat channel, short guard interval), as set
+ * up in the rate scaling table in the Link Quality command.  The driver must
+ * determine which rate table entry was used for each tx attempt, to determine
+ * which rate-specific history to update, and record only those attempts that
+ * match the modulation characteristics of the history set.
+ *
+ * When using block-ack (aggregation), all frames are transmitted at the same
+ * rate, since there is no per-attempt acknowledgment from the destination
+ * station.  The Tx response struct iwl_tx_resp indicates the Tx rate in
+ * rate_n_flags field.  After receiving a block-ack, the driver can update
+ * history for the entire block all at once.
+ *
+ *
+ * FINDING BEST STARTING RATE:
+ *
+ * When working with a selected initial modulation mode (see below), the
+ * driver attempts to find a best initial rate.  The initial rate is the
+ * first entry in the Link Quality command's rate table.
+ *
+ * 1)  Calculate actual throughput (success ratio * expected throughput, see
+ *     table below) for current initial rate.  Do this only if enough frames
+ *     have been attempted to make the value meaningful:  at least 6 failed
+ *     tx attempts, or at least 8 successes.  If not enough, don't try rate
+ *     scaling yet.
+ *
+ * 2)  Find available rates adjacent to current initial rate.  Available means:
+ *     a)  supported by hardware &&
+ *     b)  supported by association &&
+ *     c)  within any constraints selected by user
+ *
+ * 3)  Gather measured throughputs for adjacent rates.  These might not have
+ *     enough history to calculate a throughput.  That's okay, we might try
+ *     using one of them anyway!
+ *
+ * 4)  Try decreasing rate if, for current rate:
+ *     a)  success ratio is < 15% ||
+ *     b)  lower adjacent rate has better measured throughput ||
+ *     c)  higher adjacent rate has worse throughput, and lower is unmeasured
+ *
+ *     As a sanity check, if decrease was determined above, leave rate
+ *     unchanged if:
+ *     a)  lower rate unavailable
+ *     b)  success ratio at current rate > 85% (very good)
+ *     c)  current measured throughput is better than expected throughput
+ *         of lower rate (under perfect 100% tx conditions, see table below)
+ *
+ * 5)  Try increasing rate if, for current rate:
+ *     a)  success ratio is < 15% ||
+ *     b)  both adjacent rates' throughputs are unmeasured (try it!) ||
+ *     b)  higher adjacent rate has better measured throughput ||
+ *     c)  lower adjacent rate has worse throughput, and higher is unmeasured
+ *
+ *     As a sanity check, if increase was determined above, leave rate
+ *     unchanged if:
+ *     a)  success ratio at current rate < 70%.  This is not particularly
+ *         good performance; higher rate is sure to have poorer success.
+ *
+ * 6)  Re-evaluate the rate after each tx frame.  If working with block-
+ *     acknowledge, history and statistics may be calculated for the entire
+ *     block (including prior history that fits within the history windows),
+ *     before re-evaluation.
+ *
+ * FINDING BEST STARTING MODULATION MODE:
+ *
+ * After working with a modulation mode for a "while" (and doing rate scaling),
+ * the driver searches for a new initial mode in an attempt to improve
+ * throughput.  The "while" is measured by numbers of attempted frames:
+ *
+ * For legacy mode, search for new mode after:
+ *   480 successful frames, or 160 failed frames
+ * For high-throughput modes (SISO or MIMO), search for new mode after:
+ *   4500 successful frames, or 400 failed frames
+ *
+ * Mode switch possibilities are (3 for each mode):
+ *
+ * For legacy:
+ *   Change antenna, try SISO (if HT association), try MIMO (if HT association)
+ * For SISO:
+ *   Change antenna, try MIMO, try shortened guard interval (SGI)
+ * For MIMO:
+ *   Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
+ *
+ * When trying a new mode, use the same bit rate as the old/current mode when
+ * trying antenna switches and shortened guard interval.  When switching to
+ * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
+ * for which the expected throughput (under perfect conditions) is about the
+ * same or slightly better than the actual measured throughput delivered by
+ * the old/current mode.
+ *
+ * Actual throughput can be estimated by multiplying the expected throughput
+ * by the success ratio (successful / attempted tx frames).  Frame size is
+ * not considered in this calculation; it assumes that frame size will average
+ * out to be fairly consistent over several samples.  The following are
+ * metric values for expected throughput assuming 100% success ratio.
+ * Only G band has support for CCK rates:

+ * REPLY_SCAN_CMD = 0x80 (command)
+ *
+ * The hardware scan command is very powerful; the driver can set it up to
+ * maintain (relatively) normal network traffic while doing a scan in the
+ * background.  The max_out_time and suspend_time control the ratio of how
+ * long the device stays on an associated network channel ("service channel")
+ * vs. how long it's away from the service channel, i.e. tuned to other channels
+ * for scanning.
+ *
+ * max_out_time is the max time off-channel (in usec), and suspend_time
+ * is how long (in "extended beacon" format) that the scan is "suspended"
+ * after returning to the service channel.  That is, suspend_time is the
+ * time that we stay on the service channel, doing normal work, between
+ * scan segments.  The driver may set these parameters differently to support
+ * scanning when associated vs. not associated, and light vs. heavy traffic
+ * loads when associated.
+ *
+ * After receiving this command, the device's scan engine does the following;
+ *
+ * 1)  Sends SCAN_START notification to driver
+ * 2)  Checks to see if it has time to do scan for one channel
+ * 3)  Sends NULL packet, with power-save (PS) bit set to 1,
+ *     to tell AP that we're going off-channel
+ * 4)  Tunes to first channel in scan list, does active or passive scan
+ * 5)  Sends SCAN_RESULT notification to driver
+ * 6)  Checks to see if it has time to do scan on *next* channel in list
+ * 7)  Repeats 4-6 until it no longer has time to scan the next channel
+ *     before max_out_time expires
+ * 8)  Returns to service channel
+ * 9)  Sends NULL packet with PS=0 to tell AP that we're back
+ * 10) Stays on service channel until suspend_time expires
+ * 11) Repeats entire process 2-10 until list is complete
+ * 12) Sends SCAN_COMPLETE notification
+ *
+ * For fast, efficient scans, the scan command also has support for staying on
+ * a channel for just a short time, if doing active scanning and getting no
+ * responses to the transmitted probe request.  This time is controlled by
+ * quiet_time, and the number of received packets below which a channel is
+ * considered "quiet" is controlled by quiet_plcp_threshold.
+ *
+ * For active scanning on channels that have regulatory restrictions against
+ * blindly transmitting, the scan can listen before transmitting, to make sure
+ * that there is already legitimate activity on the channel.  If enough
+ * packets are cleanly received on the channel (controlled by good_CRC_th,
+ * typical value 1), the scan engine starts transmitting probe requests.
+ *
+ * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
+ *
+ * To avoid uCode errors, see timing restrictions described under
+ * struct iwl_scan_channel.

+ *
+ *****************************************************************************/
+
+/**
+ * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
+ *
+ * This command sets up the Rx signal detector for a sensitivity level that
+ * is high enough to lock onto all signals within the associated network,
+ * but low enough to ignore signals that are below a certain threshold, so as
+ * not to have too many "false alarms".  False alarms are signals that the
+ * Rx DSP tries to lock onto, but then discards after determining that they
+ * are noise.
+ *
+ * The optimum number of false alarms is between 5 and 50 per 200 TUs
+ * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
+ * time listening, not transmitting).  Driver must adjust sensitivity so that
+ * the ratio of actual false alarms to actual Rx time falls within this range.
+ *
+ * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
+ * received beacon.  These provide information to the driver to analyze the
+ * sensitivity.  Don't analyze statistics that come in from scanning, or any
+ * other non-associated-network source.  Pertinent statistics include:
+ *
+ * From "general" statistics (struct statistics_rx_non_phy):
+ *
+ * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
+ *   Measure of energy of desired signal.  Used for establishing a level
+ *   below which the device does not detect signals.
+ *
+ * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
+ *   Measure of background noise in silent period after beacon.
+ *
+ * channel_load
+ *   uSecs of actual Rx time during beacon period (varies according to
+ *   how much time was spent transmitting).
+ *
+ * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
+ *
+ * false_alarm_cnt
+ *   Signal locks abandoned early (before phy-level header).
+ *
+ * plcp_err
+ *   Signal locks abandoned late (during phy-level header).
+ *
+ * NOTE:  Both false_alarm_cnt and plcp_err increment monotonically from
+ *        beacon to beacon, i.e. each value is an accumulation of all errors
+ *        before and including the latest beacon.  Values will wrap around to 0
+ *        after counting up to 2^32 - 1.  Driver must differentiate vs.
+ *        previous beacon's values to determine # false alarms in the current
+ *        beacon period.
+ *
+ * Total number of false alarms = false_alarms + plcp_errs
+ *
+ * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
+ * (notice that the start points for OFDM are at or close to settings for
+ * maximum sensitivity):
+ *
+ *                                             START  /  MIN  /  MAX
+ *   HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX          90   /   85  /  120
+ *   HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX     170   /  170  /  210
+ *   HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX         105   /  105  /  140
+ *   HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX     220   /  220  /  270
+ *
+ *   If actual rate of OFDM false alarms (+ plcp_errors) is too high
+ *   (greater than 50 for each 204.8 msecs listening), reduce sensitivity
+ *   by *adding* 1 to all 4 of the table entries above, up to the max for
+ *   each entry.  Conversely, if false alarm rate is too low (less than 5
+ *   for each 204.8 msecs listening), *subtract* 1 from each entry to
+ *   increase sensitivity.
+ *
+ * For CCK sensitivity, keep track of the following:
+ *
+ *   1).  20-beacon history of maximum background noise, indicated by
+ *        (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
+ *        3 receivers.  For any given beacon, the "silence reference" is
+ *        the maximum of last 60 samples (20 beacons * 3 receivers).
+ *
+ *   2).  10-beacon history of strongest signal level, as indicated
+ *        by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
+ *        i.e. the strength of the signal through the best receiver at the
+ *        moment.  These measurements are "upside down", with lower values
+ *        for stronger signals, so max energy will be *minimum* value.
+ *
+ *        Then for any given beacon, the driver must determine the *weakest*
+ *        of the strongest signals; this is the minimum level that needs to be
+ *        successfully detected, when using the best receiver at the moment.
+ *        "Max cck energy" is the maximum (higher value means lower energy!)
+ *        of the last 10 minima.  Once this is determined, driver must add
+ *        a little margin by adding "6" to it.
+ *
+ *   3).  Number of consecutive beacon periods with too few false alarms.
+ *        Reset this to 0 at the first beacon period that falls within the
+ *        "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
+ *
+ * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
+ * (notice that the start points for CCK are at maximum sensitivity):
+ *
+ *                                             START  /  MIN  /  MAX
+ *   HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX         125   /  125  /  200
+ *   HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX     200   /  200  /  400
+ *   HD_MIN_ENERGY_CCK_DET_INDEX                100   /    0  /  100
+ *
+ *   If actual rate of CCK false alarms (+ plcp_errors) is too high
+ *   (greater than 50 for each 204.8 msecs listening), method for reducing
+ *   sensitivity is:
+ *
+ *   1)  *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
+ *       up to max 400.
+ *
+ *   2)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
+ *       sensitivity has been reduced a significant amount; bring it up to
+ *       a moderate 161.  Otherwise, *add* 3, up to max 200.
+ *
+ *   3)  a)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
+ *       sensitivity has been reduced only a moderate or small amount;
+ *       *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
+ *       down to min 0.  Otherwise (if gain has been significantly reduced),
+ *       don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
+ *
+ *       b)  Save a snapshot of the "silence reference".
+ *
+ *   If actual rate of CCK false alarms (+ plcp_errors) is too low
+ *   (less than 5 for each 204.8 msecs listening), method for increasing
+ *   sensitivity is used only if:
+ *
+ *   1a)  Previous beacon did not have too many false alarms
+ *   1b)  AND difference between previous "silence reference" and current
+ *        "silence reference" (prev - current) is 2 or more,
+ *   OR 2)  100 or more consecutive beacon periods have had rate of
+ *          less than 5 false alarms per 204.8 milliseconds rx time.
+ *
+ *   Method for increasing sensitivity:
+ *
+ *   1)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,

+ * REPLY_PHY_CALIBRATION_CMD = 0xb0 (command, has simple generic response)
+ *
+ * This command sets the relative gains of 4965 device's 3 radio receiver chains.
+ *
+ * After the first association, driver should accumulate signal and noise
+ * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20
+ * beacons from the associated network (don't collect statistics that come
+ * in from scanning, or any other non-network source).
+ *
+ * DISCONNECTED ANTENNA:
+ *
+ * Driver should determine which antennas are actually connected, by comparing
+ * average beacon signal levels for the 3 Rx chains.  Accumulate (add) the
+ * following values over 20 beacons, one accumulator for each of the chains
+ * a/b/c, from struct statistics_rx_non_phy:
+ *
+ * beacon_rssi_[abc] & 0x0FF (unsigned, units in dB)
+ *
+ * Find the strongest signal from among a/b/c.  Compare the other two to the
+ * strongest.  If any signal is more than 15 dB (times 20, unless you
+ * divide the accumulated values by 20) below the strongest, the driver
+ * considers that antenna to be disconnected, and should not try to use that
+ * antenna/chain for Rx or Tx.  If both A and B seem to be disconnected,
+ * driver should declare the stronger one as connected, and attempt to use it
+ * (A and B are the only 2 Tx chains!).
+ *
+ *
+ * RX BALANCE:
+ *
+ * Driver should balance the 3 receivers (but just the ones that are connected
+ * to antennas, see above) for gain, by comparing the average signal levels
+ * detected during the silence after each beacon (background noise).
+ * Accumulate (add) the following values over 20 beacons, one accumulator for
+ * each of the chains a/b/c, from struct statistics_rx_non_phy:
+ *
+ * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
+ *
+ * Find the weakest background noise level from among a/b/c.  This Rx chain
+ * will be the reference, with 0 gain adjustment.  Attenuate other channels by
+ * finding noise difference:
+ *
+ * (accum_noise[i] - accum_noise[reference]) / 30
+ *
+ * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
+ * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
+ * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
+ * and set bit 2 to indicate "reduce gain".  The value for the reference
+ * (weakest) chain should be "0".
+ *
+ * diff_gain_[abc] bit fields:
+ *   2: (1) reduce gain, (0) increase gain

+ * highest and @ucode_api_min the lowest). Firmware will only be loaded if
+ * it has a supported API version. The firmware's API version will be

+ * on firmware version used.
+ *
+ * For example,

+ *	Driver interacts with Firmware API version >= 2.
+ * } else {
+ *	Driver interacts with Firmware API version 1.
+ * }

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwlegacy_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel.  We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware.  This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel.  There is no corresponding channel information for that
+ * entry.

+ *     (RBs) have been filled, via a "write pointer", actually the index of
+ *     the RB's corresponding RBD within the circular buffer.  Driver sets

+ *     11- 0:  Index of last filled Rx buffer descriptor
+ *             (4965 writes, driver reads this value)
+ *
+ * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
+ * enter pointers to these RBs into contiguous RBD circular buffer entries,
+ * and update the 4965's "write" index register,
+ * FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
+ *
+ * This "write" index corresponds to the *next* RBD that the driver will make
+ * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
+ * the circular buffer.  This value should initially be 0 (before preparing any
+ * RBs), should be 8 after preparing the first 8 RBs (for example), and must
+ * wrap back to 0 at the end of the circular buffer (but don't wrap before
+ * "read" index has advanced past 1!  See below).
+ * NOTE:  4965 EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
+ *
+ * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
+ * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
+ * to tell the driver the index of the latest filled RBD.  The driver must
+ * read this "read" index from DRAM after receiving an Rx interrupt from 4965.
+ *
+ * The driver must also internally keep track of a third index, which is the
+ * next RBD to process.  When receiving an Rx interrupt, driver should process
+ * all filled but unprocessed RBs up to, but not including, the RB
+ * corresponding to the "read" index.  For example, if "read" index becomes "1",
+ * driver may process the RB pointed to by RBD 0.  Depending on volume of
+ * traffic, there may be many RBs to process.
+ *
+ * If read index == write index, 4965 thinks there is no room to put new data.
+ * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
+ * be safe, make sure that there is a gap of at least 2 RBDs between "write"
+ * and "read" indexes; that is, make sure that there are no more than 254
+ * buffers waiting to be filled.

+/**
+ * BSM (Bootstrap State Machine)
+ *
+ * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
+ * in special SRAM that does not power down when the embedded control
+ * processor is sleeping (e.g. for periodic power-saving shutdowns of radio).
+ *
+ * When powering back up after sleeps (or during initial uCode load), the BSM
+ * internally loads the short bootstrap program from the special SRAM into the
+ * embedded processor's instruction SRAM, and starts the processor so it runs
+ * the bootstrap program.
+ *
+ * This bootstrap program loads (via PCI busmaster DMA) instructions and data
+ * images for a uCode program from host DRAM locations.  The host driver
+ * indicates DRAM locations and sizes for instruction and data images via the
+ * four BSM_DRAM_* registers.  Once the bootstrap program loads the new program,
+ * the new program starts automatically.
+ *
+ * The uCode used for open-source drivers includes two programs:
+ *
+ * 1)  Initialization -- performs hardware calibration and sets up some
+ *     internal data, then notifies host via "initialize alive" notification
+ *     (struct iwl_init_alive_resp) that it has completed all of its work.
+ *     After signal from host, it then loads and starts the runtime program.
+ *     The initialization program must be used when initially setting up the
+ *     NIC after loading the driver.
+ *
+ * 2)  Runtime/Protocol -- performs all normal runtime operations.  This
+ *     notifies host via "alive" notification (struct iwl_alive_resp) that it
+ *     is ready to be used.
+ *
+ * When initializing the NIC, the host driver does the following procedure:
+ *
+ * 1)  Load bootstrap program (instructions only, no data image for bootstrap)
+ *     into bootstrap memory.  Use dword writes starting at BSM_SRAM_LOWER_BOUND
+ *
+ * 2)  Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction
+ *     images in host DRAM.
+ *
+ * 3)  Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked:
+ *     BSM_WR_MEM_SRC_REG = 0
+ *     BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND
+ *     BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image
+ *
+ * 4)  Load bootstrap into instruction SRAM:
+ *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START
+ *
+ * 5)  Wait for load completion:
+ *     Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0
+ *
+ * 6)  Enable future boot loads whenever NIC's power management triggers it:
+ *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN
+ *
+ * 7)  Start the NIC by removing all reset bits:
+ *     CSR_RESET = 0
+ *
+ *     The bootstrap uCode (already in instruction SRAM) loads initialization
+ *     uCode.  Initialization uCode performs data initialization, sends
+ *     "initialize alive" notification to host, and waits for a signal from
+ *     host to load runtime code.
+ *
+ * 4)  Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction
+ *     images in host DRAM.  The last register loaded must be the instruction
+ *     byte count register ("1" in MSbit tells initialization uCode to load
+ *     the runtime uCode):
+ *     BSM_DRAM_INST_BYTECOUNT_REG = byte count | BSM_DRAM_INST_LOAD
+ *
+ * 5)  Wait for "alive" notification, then issue normal runtime commands.
+ *
+ * Data caching during power-downs:
+ *
+ * Just before the embedded controller powers down (e.g for automatic
+ * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA)
+ * a current snapshot of the embedded processor's data SRAM into host DRAM.
+ * This caches the data while the embedded processor's memory is powered down.
+ * Location and size are controlled by BSM_DRAM_DATA_* registers.
+ *
+ * NOTE:  Instruction SRAM does not need to be saved, since that doesn't
+ *        change during operation; the original image (from uCode distribution
+ *        file) can be used for reload.
+ *
+ * When powering back up, the BSM loads the bootstrap program.  Bootstrap looks
+ * at the BSM_DRAM_* registers, which now point to the runtime instruction
+ * image and the cached (modified) runtime data (*not* the initialization
+ * uCode).  Bootstrap reloads these runtime images into SRAM, and restarts the
+ * uCode from where it left off before the power-down.
+ *
+ * NOTE:  Initialization uCode does *not* run as part of the save/restore
+ *        procedure.
+ *
+ * This save/restore method is mostly for autonomous power management during
+ * normal operation (result of POWER_TABLE_CMD).  Platform suspend/resume and
+ * RFKILL should use complete restarts (with total re-initialization) of uCode,
+ * allowing total shutdown (including BSM memory).
+ *
+ * Note that, during normal operation, the host DRAM that held the initial
+ * startup data for the runtime code is now being used as a backup data cache
+ * for modified data!  If you need to completely re-initialize the NIC, make
+ * sure that you use the runtime data image from the uCode distribution file,
+ * not the modified/saved runtime data.  You may want to store a separate
+ * "clean" runtime data image in DRAM to avoid disk reads of distribution file.

+/**
+ * Tx Scheduler
+ *
+ * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
+ * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
+ * host DRAM.  It steers each frame's Tx command (which contains the frame
+ * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
+ * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
+ * but one DMA channel may take input from several queues.
+ *
+ * Tx DMA FIFOs have dedicated purposes.  For 4965, they are used as follows
+ * (cf. default_queue_to_tx_fifo in iwl-4965.c):
+ *
+ * 0 -- EDCA BK (background) frames, lowest priority
+ * 1 -- EDCA BE (best effort) frames, normal priority
+ * 2 -- EDCA VI (video) frames, higher priority
+ * 3 -- EDCA VO (voice) and management frames, highest priority
+ * 4 -- Commands (e.g. RXON, etc.)
+ * 5 -- unused (HCCA)
+ * 6 -- unused (HCCA)
+ * 7 -- not used by driver (device-internal only)
+ *
+ *
+ * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
+ * In addition, driver can map the remaining queues to Tx DMA/FIFO
+ * channels 0-3 to support 11n aggregation via EDCA DMA channels.
+ *
+ * The driver sets up each queue to work in one of two modes:
+ *
+ * 1)  Scheduler-Ack, in which the scheduler automatically supports a
+ *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
+ *     contains TFDs for a unique combination of Recipient Address (RA)
+ *     and Traffic Identifier (TID), that is, traffic of a given
+ *     Quality-Of-Service (QOS) priority, destined for a single station.
+ *
+ *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
+ *     each frame within the BA window, including whether it's been transmitted,
+ *     and whether it's been acknowledged by the receiving station.  The device
+ *     automatically processes block-acks received from the receiving STA,
+ *     and reschedules un-acked frames to be retransmitted (successful
+ *     Tx completion may end up being out-of-order).
+ *
+ *     The driver must maintain the queue's Byte Count table in host DRAM
+ *     (struct iwl4965_sched_queue_byte_cnt_tbl) for this mode.
+ *     This mode does not support fragmentation.
+ *
+ * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
+ *     The device may automatically retry Tx, but will retry only one frame
+ *     at a time, until receiving ACK from receiving station, or reaching
+ *     retry limit and giving up.
+ *
+ *     The command queue (#4/#9) must use this mode!
+ *     This mode does not require use of the Byte Count table in host DRAM.
+ *
+ * Driver controls scheduler operation via 3 means:
+ * 1)  Scheduler registers
+ * 2)  Shared scheduler data base in internal 4956 SRAM
+ * 3)  Shared data in host DRAM
+ *
+ * Initialization:
+ *
+ * When loading, driver should allocate memory for:
+ * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
+ * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
+ *     (1024 bytes for each queue).
+ *
+ * After receiving "Alive" response from uCode, driver must initialize
+ * the scheduler (especially for queue #4/#9, the command queue, otherwise
+ * the driver can't issue commands!):
+ */
+
+/**
+ * Max Tx window size is the max number of contiguous TFDs that the scheduler
+ * can keep track of at one time when creating block-ack chains of frames.
+ * Note that "64" matches the number of ack bits in a block-ack packet.
+ * Driver should use SCD_WIN_SIZE and SCD_FRAME_LIMIT values to initialize
+ * IWL49_SCD_CONTEXT_QUEUE_OFFSET(x) values.

+/************************** RX-FUNCTIONS ****************************/
+/*
+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC.  These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC.  The driver and NIC manage the Rx buffers by means
+ * of indexes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ index
+ * and fire the RX interrupt.  The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replenish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ *   detached from the iwl->rxq.  The driver 'processed' index is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
+ *   were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * iwl_legacy_rx_queue_alloc()   Allocates rx_free
+ * iwl_rx_replenish()     Replenishes rx_free list from rx_used, and calls
+ *                            iwl_rx_queue_restock
+ * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
+ *                            queue, updates firmware pointers, and updates
+ *                            the WRITE index.  If insufficient rx_free buffers
+ *                            are available, schedules iwl_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - iwl_rx()         Detach iwl_rx_mem_buffers from pool up to the
+ *                            READ INDEX, detaching the SKB from the pool.
+ *                            Moves the packet buffer from queue to rx_used.
+ *                            Calls iwl_rx_queue_restock to refill any empty
+ *                            slots.

+ *
+ * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
+ * of buffer descriptors, each of which points to one or more data buffers for
+ * the device to read from or fill.  Driver and device exchange status of each
+ * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
+ * entries in each circular buffer, to protect against confusing empty and full
+ * queue states.
+ *
+ * The device reads or writes the data in the queues via the device's several
+ * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.

+	  This module implements a driver for a wide range of different
+	  Samsung laptops.  It offers control over the different
+	  function keys, wireless LED, LCD backlight level, and
+	  sometimes provides a "performance_control" sysfs file to allow
+	  the performance level of the laptop to be changed.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called samsung-laptop.

+	 *     day/month/year calendar data.

+	 *     Linux uses only oneshot alarms.
+	 *
+	 * When we see that here, we deal with it by using values from
+	 * a current RTC timestamp for any missing (-1) values.  The
+	 * RTC driver prevents "periodic alarm" modes.
+	 *
+	 * But this can be racey, because some fields of the RTC timestamp
+	 * may have wrapped in the interval since we read the RTC alarm,
+	 * which would lead to us inserting inconsistent values in place
+	 * of the -1 fields.
+	 *
+	 * Reading the alarm and timestamp in the reverse sequence
+	 * would have the same race condition, and not solve the issue.
+	 *
+	 * So, we must first read the RTC timestamp,
+	 * then read the RTC alarm value,
+	 * and then read a second RTC timestamp.
+	 *
+	 * If any fields of the second timestamp have changed
+	 * when compared with the first timestamp, then we know
+	 * our timestamp may be inconsistent with that used by
+	 * the low-level rtc_read_alarm_internal() function.
+	 *
+	 * So, when the two timestamps disagree, we just loop and do
+	 * the process again to get a fully consistent set of values.
+	 *

+
+/*
+ * iDiag PCI config space register access methods:
+ *
+ * The PCI config space register accessees of read, write, read-modify-write
+ * for set bits, and read-modify-write for clear bits to SLI4 PCI functions
+ * are provided. In the proper SLI4 PCI function's debugfs iDiag directory,
+ *
+ *      /sys/kernel/debug/lpfc/fn<#>/iDiag
+ *
+ * the access is through the debugfs entry pciCfg:
+ *
+ * 1. For PCI config space register read access, there are two read methods:
+ *    A) read a single PCI config space register in the size of a byte
+ *    (8 bits), a word (16 bits), or a dword (32 bits); or B) browse through
+ *    the 4K extended PCI config space.
+ *
+ *    A) Read a single PCI config space register consists of two steps:
+ *
+ *    Step-1: Set up PCI config space register read command, the command
+ *    syntax is,
+ *
+ *        echo 1 <where> <count> > pciCfg
+ *
+ *    where, 1 is the iDiag command for PCI config space read, <where> is the
+ *    offset from the beginning of the device's PCI config space to read from,
+ *    and <count> is the size of PCI config space register data to read back,
+ *    it will be 1 for reading a byte (8 bits), 2 for reading a word (16 bits
+ *    or 2 bytes), or 4 for reading a dword (32 bits or 4 bytes).
+ *
+ *    Setp-2: Perform the debugfs read operation to execute the idiag command
+ *    set up in Step-1,
+ *
+ *        cat pciCfg
+ *
+ *    Examples:
+ *    To read PCI device's vendor-id and device-id from PCI config space,
+ *
+ *        echo 1 0 4 > pciCfg
+ *        cat pciCfg
+ *
+ *    To read PCI device's currnt command from config space,
+ *
+ *        echo 1 4 2 > pciCfg
+ *        cat pciCfg
+ *
+ *    B) Browse through the entire 4K extended PCI config space also consists
+ *    of two steps:
+ *
+ *    Step-1: Set up PCI config space register browsing command, the command
+ *    syntax is,
+ *
+ *        echo 1 0 4096 > pciCfg
+ *
+ *    where, 1 is the iDiag command for PCI config space read, 0 must be used
+ *    as the offset for PCI config space register browse, and 4096 must be
+ *    used as the count for PCI config space register browse.
+ *
+ *    Step-2: Repeately issue the debugfs read operation to browse through
+ *    the entire PCI config space registers:
+ *
+ *        cat pciCfg
+ *        cat pciCfg
+ *        cat pciCfg
+ *        ...
+ *
+ *    When browsing to the end of the 4K PCI config space, the browse method
+ *    shall wrap around to start reading from beginning again, and again...
+ *
+ * 2. For PCI config space register write access, it supports a single PCI
+ *    config space register write in the size of a byte (8 bits), a word
+ *    (16 bits), or a dword (32 bits). The command syntax is,
+ *
+ *        echo 2 <where> <count> <value> > pciCfg
+ *
+ *    where, 2 is the iDiag command for PCI config space write, <where> is
+ *    the offset from the beginning of the device's PCI config space to write
+ *    into, <count> is the size of data to write into the PCI config space,
+ *    it will be 1 for writing a byte (8 bits), 2 for writing a word (16 bits
+ *    or 2 bytes), or 4 for writing a dword (32 bits or 4 bytes), and <value>
+ *    is the data to be written into the PCI config space register at the
+ *    offset.
+ *
+ *    Examples:
+ *    To disable PCI device's interrupt assertion,
+ *
+ *    1) Read in device's PCI config space register command field <cmd>:
+ *
+ *           echo 1 4 2 > pciCfg
+ *           cat pciCfg
+ *
+ *    2) Set bit 10 (Interrupt Disable bit) in the <cmd>:
+ *
+ *           <cmd> = <cmd> | (1 < 10)
+ *
+ *    3) Write the modified command back:
+ *
+ *           echo 2 4 2 <cmd> > pciCfg
+ *
+ * 3. For PCI config space register set bits access, it supports a single PCI
+ *    config space register set bits in the size of a byte (8 bits), a word
+ *    (16 bits), or a dword (32 bits). The command syntax is,
+ *
+ *        echo 3 <where> <count> <bitmask> > pciCfg
+ *
+ *    where, 3 is the iDiag command for PCI config space set bits, <where> is
+ *    the offset from the beginning of the device's PCI config space to set
+ *    bits into, <count> is the size of the bitmask to set into the PCI config
+ *    space, it will be 1 for setting a byte (8 bits), 2 for setting a word
+ *    (16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 bytes), and
+ *    <bitmask> is the bitmask, indicating the bits to be set into the PCI
+ *    config space register at the offset. The logic performed to the content
+ *    of the PCI config space register, regval, is,
+ *
+ *        regval |= <bitmask>
+ *
+ * 4. For PCI config space register clear bits access, it supports a single
+ *    PCI config space register clear bits in the size of a byte (8 bits),
+ *    a word (16 bits), or a dword (32 bits). The command syntax is,
+ *
+ *        echo 4 <where> <count> <bitmask> > pciCfg
+ *
+ *    where, 4 is the iDiag command for PCI config space clear bits, <where>
+ *    is the offset from the beginning of the device's PCI config space to
+ *    clear bits from, <count> is the size of the bitmask to set into the PCI
+ *    config space, it will be 1 for setting a byte (8 bits), 2 for setting
+ *    a word(16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4
+ *    bytes), and <bitmask> is the bitmask, indicating the bits to be cleared
+ *    from the PCI config space register at the offset. the logic performed
+ *    to the content of the PCI config space register, regval, is,
+ *
+ *        regval &= ~<bitmask>
+ *
+ * Note, for all single register read, write, set bits, or clear bits access,
+ * the offset (<where>) must be aligned with the size of the data:
+ *
+ * For data size of byte (8 bits), the offset must be aligned to the byte
+ * boundary; for data size of word (16 bits), the offset must be aligned
+ * to the word boundary; while for data size of dword (32 bits), the offset
+ * must be aligned to the dword boundary. Otherwise, the interface will
+ * return the error:
+ *
+ *     "-bash: echo: write error: Invalid argument".
+ *
+ * For example:
+ *
+ *     echo 1 2 4 > pciCfg
+ *     -bash: echo: write error: Invalid argument
+ *
+ * Note also, all of the numbers in the command fields for all read, write,
+ * set bits, and clear bits PCI config space register command fields can be
+ * either decimal or hex.
+ *
+ * For example,
+ *     echo 1 0 4096 > pciCfg
+ *
+ * will be the same as
+ *     echo 1 0 0x1000 > pciCfg
+ *
+ * And,
+ *     echo 2 155 1 10 > pciCfg
+ *
+ * will be
+ *     echo 2 0x9b 1 0xa > pciCfg

-	tristate "Kernel automounter support"
-	depends on BKL # unfixable, just use autofs4
-	help
-	  The automounter is a tool to automatically mount remote file systems
-	  on demand. This implementation is partially kernel-based to reduce
-	  overhead in the already-mounted case; this is unlike the BSD
-	  automounter (amd), which is a pure user space daemon.
-
-	  To use the automounter you need the user-space tools from the autofs
-	  package; you can find the location in <file:Documentation/Changes>.
-	  You also want to answer Y to "NFS file system support", below.
-
-	  If you want to use the newer version of the automounter with more
-	  features, say N here and say Y to "Kernel automounter v4 support",
-	  below.
-
-	  To compile this support as a module, choose M here: the module will be
-	  called autofs.
-
-	  If you are not a part of a fairly large, distributed network, you
-	  probably do not need an automounter, and can say N here.

+ - Encrypted data must be written to 'sec0'.
+ - Decrypted data can be read from 'sec0'.
+ - Setup the CAM using device 'ca0'.
+
+But this is wrong. There are some discussions about the proper way for
+doing it, as seen at:
+	http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html
+
+While there's no proper fix for it, the driver should be kept in staging.
+
+Patches should be submitted to: linux-media@vger.kernel.org.

+	  This option supports the 2232 7-port serial card shipped with the
+	  Amiga 2000 and other Zorro-bus machines, dating from 1989.  At
+	  a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip

+	  ports were connected with 8 pin DIN connectors on the card bracket,
+	  for which 8 pin to DB25 adapters were supplied. The card also had
+	  jumpers internally to toggle various pinning configurations.
+
+	  This driver can be built as a module; but then "generic_serial"
+	  will also be built as a module. This has to be loaded before
+	  "ser_a2232". If you want to do this, answer M here.

+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ *	Index		Key Name
+ *	0		FullyQualifiedDomainName
+ *	1		IntegrationServicesVersion
+ *	2		NetworkAddressIPv4
+ *	3		NetworkAddressIPv6
+ *	4		OSBuildNumber
+ *	5		OSName
+ *	6		OSMajorVersion
+ *	7		OSMinorVersion
+ *	8		OSVersion
+ *	9		ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.

+====================

+Supported chips:
+  * Maxim MAX517, MAX518, MAX519
+    Prefix: 'max517'
+    Datasheet: Publicly available at the Maxim website

+Author:

+
+Description
+-----------
+
+The Maxim MAX517/518/519 is an 8-bit DAC on the I2C bus. The following table
+shows the different feature sets of the variants MAX517, MAX518 and MAX519:
+
+Feature                              MAX517 MAX518 MAX519
+--------------------------------------------------------------------------
+One output channel                   X
+Two output channels                         X      X
+Simultaneous output updates                 X      X
+Supply voltage as reference                 X
+Separate reference input             X
+Reference input for each DAC                       X
+
+Via the iio sysfs interface, there are three attributes available: out1_raw,
+out2_raw and out12_raw. With out1_raw and out2_raw, the current output values
+(0..255) of the DACs can be written to the device. out12_raw can be used to set
+both output channel values simultaneously.
+
+With MAX517, only out1_raw is available.
+
+Via out1_scale (and where appropriate, out2_scale), the current scaling factor
+in mV can be read.
+
+When the operating system goes to a power down state, the Power Down function
+of the chip is activated, reducing the supply current to 4uA.
+
+On power-up, the device is in 0V-output state.

-1. Both ir-kbd-i2c and lirc_zilog provide support for RX events.
-The 'tx_only' lirc_zilog module parameter will allow ir-kbd-i2c
-and lirc_zilog to coexist in the kernel, if the user requires such a set-up.
-However the IR unit will not work well without coordination between the
-two modules.  A shared mutex, for transceiver access locking, needs to be
-supplied by bridge drivers, in struct IR_i2_init_data, to both ir-kbd-i2c
-and lirc_zilog, before they will coexist usefully.  This should be fixed
-before moving out of staging.
-
-2. References and locking need careful examination.  For cx18 and ivtv PCI
-cards, which are not easily "hot unplugged", the imperfect state of reference
-counting and locking is acceptable if not correct.  For USB connected units
-like HD PVR, PVR USB2, HVR-1900, and HVR1950, the likelyhood of an Ooops on
-unplug is probably great.  Proper reference counting and locking needs to be
-implemented before this module is moved out of staging.
-
-3. The binding between hdpvr and lirc_zilog is currently disabled,
-due to an OOPS reported a few years ago when both the hdpvr and cx18
-drivers were loaded in his system. More details can be seen at:
-	http://www.mail-archive.com/linux-media@vger.kernel.org/msg09163.html
-More tests need to be done, in order to fix the reported issue.
-
-4. In addition to providing a shared mutex for transceiver access
-locking, bridge drivers, if able, should provide a chip reset() callback
+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
+the chips supported by lirc_zilog.  Before moving lirc_zilog out of staging:
+
+a. ir-kbd-i2c needs a module parameter added to allow the user to tell
+   ir-kbd-i2c to ignore Z8 IR units.
+
+b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
+   does.
+
+
+2. lirc_zilog module ref-counting need examination.  It has not been
+verified that cdev and lirc_dev will take the proper module references on
+lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
+is open.
+
+(The good news is ref-counting of lirc_zilog internal structures appears to be
+complete.  Testing has shown the cx18 module can be unloaded out from under
+irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
+effects.  The cx18 module could then be reloaded and irw properly began
+receiving button presses again and ir_send worked without error.)
+
+
+3. Bridge drivers, if able, should provide a chip reset() callback
 to lirc_zilog via struct IR_i2c_init_data.  cx18 and ivtv already have routines
-to perform Z8 chip resets via GPIO manipulations.  This will allow lirc_zilog
+to perform Z8 chip resets via GPIO manipulations.  This would allow lirc_zilog
 to bring the chip back to normal when it hangs, in the same places the
 original lirc_pvr150 driver code does.  This is not strictly needed, so it
 is not required to move lirc_zilog out of staging.

+Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed

- * The ITE8709 device seems to be the combination of IT8512 superIO chip and
- * a specific firmware running on the IT8512's embedded micro-controller.
- * In addition of the embedded micro-controller, the IT8512 chip contains a
- * CIR module and several other modules. A few modules are directly accessible
- * by the host CPU, but most of them are only accessible by the
- * micro-controller. The CIR module is only accessible by the micro-controller.
- * The battery-backed SRAM module is accessible by the host CPU and the
- * micro-controller. So one of the MC's firmware role is to act as a bridge
- * between the host CPU and the CIR module. The firmware implements a kind of
- * communication protocol using the SRAM module as a shared memory. The IT8512
- * specification is publicly available on ITE's web site, but the communication
- * protocol is not, so it was reverse-engineered.

-	---help---
-	  This driver provides a memory management interface to
-	  restricted access regions (RAR) available on the Intel
-	  Moorestown platform.
-
-	  Once locked down, restricted access regions are only
-	  accessible by specific hardware on the platform.  The x86
-	  CPU is typically not one of those platforms.  As such this
-	  driver does not access RAR, and only provides a buffer
-	  allocation/bookkeeping mechanism.
-
-	  If unsure, say N.

-RAR Handler (memrar) Driver TODO Items
-======================================
-
-Maintainer: Eugene Epshteyn <eugene.epshteyn@intel.com>
-
-memrar.h
---------
-1. This header exposes the driver's user space and kernel space
-   interfaces.  It should be moved to <linux/rar/memrar.h>, or
-   something along those lines, when this memrar driver is moved out
-   of `staging'.
-     a. It would be ideal if staging/rar_register/rar_register.h was
-        moved to the same directory.
-
-memrar_allocator.[ch]
----------------------
-1. Address potential fragmentation issues with the memrar_allocator.
-
-2. Hide struct memrar_allocator details/fields.  They need not be
-   exposed to the user.
-     a. Forward declare struct memrar_allocator.
-     b. Move all three struct definitions to `memrar_allocator.c'
-        source file.
-     c. Add a memrar_allocator_largest_free_area() function, or
-        something like that to get access to the value of the struct
-        memrar_allocator "largest_free_area" field.  This allows the
-        struct memrar_allocator fields to be completely hidden from
-        the user.  The memrar_handler code really only needs this for
-        statistic gathering on-demand.
-     d. Do the same for the "capacity" field as the
-        "largest_free_area" field.
-
-3. Move memrar_allocator.* to kernel `lib' directory since it is HW
-   neutral.
-     a. Alternatively, use lib/genalloc.c instead.
-     b. A kernel port of Doug Lea's malloc() implementation may also
-        be an option.
-
-memrar_handler.c
-----------------
-1. Split user space interface (ioctl code) from core/kernel code,
-   e.g.:
-     memrar_handler.c -> memrar_core.c, memrar_user.c

-What:		/dev/memrar
-Date:		March 2010
-KernelVersion:	2.6.34
-Contact:	Eugene Epshteyn <eugene.epshteyn@intel.com>
-Description:	The Intel Moorestown Restricted Access Region (RAR)
-		Handler driver exposes an ioctl() based interface that
-		allows a user to reserve and release blocks of RAR
-		memory.
-
-		Note:  A sysfs based one was not appropriate for the
-		RAR handler's usage model.
-
-		=========================================================
-				ioctl() Requests
-		=========================================================
-		RAR_HANDLER_RESERVE
-		-------------------
-		Description:	Reserve RAR block.
-		Type:		struct RAR_block_info
-		Direction:	in/out
-		Errors:		EINVAL (invalid RAR type or size)
-				ENOMEM (not enough RAR memory)
-
-		RAR_HANDLER_STAT
-		----------------
-		Description:	Get RAR statistics.
-		Type:		struct RAR_stat
-		Direction:	in/out
-		Errors:		EINVAL (invalid RAR type)
-
-		RAR_HANDLER_RELEASE
-		-------------------
-		Description:	Release previously reserved RAR block.
-		Type:		32 bit unsigned integer
-				(e.g. uint32_t), i.e the RAR "handle".
-		Direction:	in
-		Errors:		EINVAL (invalid RAR handle)
-
-
-		=========================================================
-			ioctl() Request Parameter Types
-		=========================================================
-		The structures referred to above are defined as
-		follows:
-
-		/**
-		 * struct RAR_block_info - user space struct that
-		 *			   describes RAR buffer
-		 * @type:	Type of RAR memory (e.g.,
-		 *		RAR_TYPE_VIDEO or RAR_TYPE_AUDIO) [in]
-		 * @size:	Requested size of a block in bytes to
-		 *		be reserved in RAR. [in]
-		 * @handle:	Handle that can be used to refer to
-		 *		reserved block. [out]
-		 *
-		 * This is the basic structure exposed to the user
-		 * space that describes a given RAR buffer.  It used
-		 * as the parameter for the RAR_HANDLER_RESERVE ioctl.
-		 * The buffer's underlying bus address is not exposed
-		 * to the user.  User space code refers to the buffer
-		 * entirely by "handle".
-		 */
-		struct RAR_block_info {
-			__u32 type;
-			__u32 size;
-			__u32 handle;
-		};
-
-		/**
-		 * struct RAR_stat - RAR statistics structure
-		 * @type:		Type of RAR memory (e.g.,
-		 *			RAR_TYPE_VIDEO or
-		 *			RAR_TYPE_AUDIO) [in]
-		 * @capacity:		Total size of RAR memory
-		 *			region. [out]
-		 * @largest_block_size:	Size of the largest reservable
-		 *			block. [out]
-		 *
-		 * This structure is used for RAR_HANDLER_STAT ioctl.
-		 */
-		struct RAR_stat {
-			__u32 type;
-			__u32 capacity;
-			__u32 largest_block_size;
-		};
-
-		Lastly, the RAR_HANDLER_RELEASE ioctl expects a
-		"handle" to the RAR block of memory.  It is a 32 bit
-		unsigned integer.

-config SMB_FS
-	tristate "SMB file system support (OBSOLETE, please use CIFS)"
-	depends on BKL # probably unfixable
-	depends on INET
-	select NLS
-	help
-	  SMB (Server Message Block) is the protocol Windows for Workgroups
-	  (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
-	  files and printers over local networks.  Saying Y here allows you to
-	  mount their file systems (often called "shares" in this context) and
-	  access them just like any other Unix directory.  Currently, this
-	  works only if the Windows machines use TCP/IP as the underlying
-	  transport protocol, and not NetBEUI.  For details, read
-	  <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
-	  available from <http://www.tldp.org/docs.html#howto>.
-
-	  Note: if you just want your box to act as an SMB *server* and make
-	  files and printing services available to Windows clients (which need
-	  to have a TCP/IP stack), you don't need to say Y here; you can use
-	  the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
-	  for that.
-
-	  General information about how to connect Linux, Windows machines and
-	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
-
-	  To compile the SMB support as a module, choose M here:
-	  the module will be called smbfs.  Most people say N, however.
-
-config SMB_NLS_DEFAULT
-	bool "Use a default NLS"
-	depends on SMB_FS
-	help
-	  Enabling this will make smbfs use nls translations by default. You
-	  need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
-	  settings and you need to give the default nls for the SMB server as
-	  CONFIG_SMB_NLS_REMOTE.
-
-	  The nls settings can be changed at mount time, if your smbmount
-	  supports that, using the codepage and iocharset parameters.
-
-	  smbmount from samba 2.2.0 or later supports this.
-
-config SMB_NLS_REMOTE
-	string "Default Remote NLS Option"
-	depends on SMB_NLS_DEFAULT
-	default "cp437"
-	help
-	  This setting allows you to specify a default value for which
-	  codepage the server uses. If this field is left blank no
-	  translations will be done by default. The local codepage/charset
-	  default to CONFIG_NLS_DEFAULT.
-
-	  The nls settings can be changed at mount time, if your smbmount
-	  supports that, using the codepage and iocharset parameters.

-Smbfs is a filesystem that implements the SMB protocol, which is the
-protocol used by Windows for Workgroups, Windows 95 and Windows NT.
-Smbfs was inspired by Samba, the program written by Andrew Tridgell
-that turns any Unix host into a file server for DOS or Windows clients.
-
-Smbfs is a SMB client, but uses parts of samba for its operation. For
-more info on samba, including documentation, please go to
-http://www.samba.org/ and then on to your nearest mirror.

-	 *    track of the queue, the FIFO, command parsing and so
-	 *    on. This is the one comparable to the 300 series.
-	 * 2. VRAM queue mode (bit 6, 0x40). In this case, one will
-	 *    have to do queue management himself. Register 0x85c4 will
-	 *    hold the location of the next free queue slot, 0x85c8
-	 *    is the "queue read pointer" whose way of working is
-	 *    unknown to me. Anyway, this mode would require a
-	 *    translation of the MMIO commands to some kind of
-	 *    accelerator assembly and writing these commands
-	 *    to the memory location pointed to by 0x85c4.
-	 *    We will not use this, as nobody knows how this
-	 *    "assembly" works, and as it would require a complete
-	 *    re-write of the accelerator code.
-	 * 3. AGP queue mode (bit 7, 0x80). Works as 2., but keeps the
-	 *    queue in AGP memory space.
-	 *
-	 * SR26 bit 4 is called "Bypass H/W queue".
-	 * SR26 bit 1 is called "Enable Command Queue Auto Correction"
-	 * SR26 bit 0 resets the queue
-	 * Size of queue memory is encoded in bits 3:2 like this:
-	 *    00  (0x00)  512K
-	 *    01  (0x04)  1M
-	 *    10  (0x08)  2M
-	 *    11  (0x0C)  4M

+ *
+ * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
+ * "handles" (triples containing a pool id, and object id, and an index), to
+ * pages in a page-accessible memory (PAM).  Tmem references the PAM pages via
+ * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
+ * set of functions (pamops).  Each pampd contains some representation of
+ * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
+ * pages and must be able to insert, find, and delete these pages at a
+ * potential frequency of thousands per second concurrently across many CPUs,
+ * (and, if used with KVM, across many vcpus across many guests).
+ * Tmem is tracked with a hierarchy of data structures, organized by
+ * the elements in a handle-tuple: pool_id, object_id, and page index.
+ * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
+ * Each pool, contains a hash table of rb_trees of tmem_objs.  Each
+ * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
+ * nodes called tmem_objnodes.  Each leaf pointer in this tree points to
+ * a pampd, which is accessible only through a small set of callbacks
+ * registered by the PAM implementation (see tmem_register_pamops). Tmem
+ * does all memory allocation via a set of callbacks registered by the tmem
+ * host implementation (e.g. see tmem_register_hostops).

+ * Zcache provides an in-kernel "host implementation" for transcendent memory
+ * and, thus indirectly, for cleancache and frontswap.  Zcache includes two
+ * page-accessible memory [1] interfaces, both utilizing lzo1x compression:
+ * 1) "compression buddies" ("zbud") is used for ephemeral pages
+ * 2) xvmalloc is used for persistent pages.
+ * Xvmalloc (based on the TLSF allocator) has very low fragmentation
+ * so maximizes space efficiency, while zbud allows pairs (and potentially,
+ * in the future, more than a pair of) compressed pages to be closely linked
+ * so that reclaiming can be done via the kernel's physical-page-oriented
+ * "shrinker" interface.
+ *
+ * [1] For a definition of page-accessible memory (aka PAM), see:
+ *   http://marc.info/?l=linux-mm&m=127811271605009

+ * Compression buddies ("zbud") provides for packing two (or, possibly
+ * in the future, more) compressed ephemeral pages into a single "raw"
+ * (physical) page and tracking them with data structures so that
+ * the raw pages can be easily reclaimed.
+ *
+ * A zbud page ("zbpg") is an aligned page containing a list_head,
+ * a lock, and two "zbud headers".  The remainder of the physical
+ * page is divided up into aligned 64-byte "chunks" which contain
+ * the compressed data for zero, one, or two zbuds.  Each zbpg
+ * resides on: (1) an "unused list" if it has no zbuds; (2) a
+ * "buddied" list if it is fully populated  with two zbuds; or
+ * (3) one of PAGE_SIZE/64 "unbuddied" lists indexed by how many chunks
+ * the one unbuddied zbud uses.  The data inside a zbpg cannot be
+ * read or written unless the zbpg's lock is held.

+config VT

+	select INPUT
+	default y
+	---help---
+	  If you say Y here, you will get support for terminal devices with
+	  display and keyboard devices. These are called "virtual" because you
+	  can run several virtual terminals (also called virtual consoles) on
+	  one physical terminal. This is rather useful, for example one
+	  virtual terminal can collect system messages and warnings, another
+	  one can be used for a text-mode user session, and a third could run
+	  an X session, all in parallel. Switching between virtual terminals
+	  is done with certain key combinations, usually Alt-<function key>.
+
+	  The setterm command ("man setterm") can be used to change the
+	  properties (such as colors or beeping) of a virtual terminal. The
+	  man page console_codes(4) ("man console_codes") contains the special
+	  character sequences that can be used to change those properties
+	  directly. The fonts used on virtual terminals can be changed with
+	  the setfont ("man setfont") command and the key bindings are defined
+	  with the loadkeys ("man loadkeys") command.
+
+	  You need at least one virtual terminal device in order to make use
+	  of your keyboard and monitor. Therefore, only people configuring an
+	  embedded system would want to say N here in order to save some
+	  memory; the only way to log into such a system is then via a serial
+	  or network connection.

+	  The system console is the device which receives all kernel messages

+	  answer Y here, a virtual terminal (the device used to interact with
+	  a physical terminal) can be used as system console. This is the most
+	  common mode of operations, so you should say Y here unless you want
+	  the kernel messages be output only to a serial port (in which case
+	  you should say Y to "Console on serial port", below).
+
+	  If you do say Y here, by default the currently visible virtual
+	  terminal (/dev/tty0) will be used as system console. You can change
+	  that with a kernel command line option such as "console=tty3" which
+	  would use the third virtual terminal as system console. (Try "man
+	  bootparam" or see the documentation of your boot loader (lilo or

+         drivers may be enabled, such as the framebuffer console. If more than

+	  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

+ * @file
+ * @brief LCDIF driver for i.MX23 and i.MX28
+ *
+ * The LCDIF support four modes of operation
+ * - MPU interface (to drive smart displays) -> not supported yet
+ * - VSYNC interface (like MPU interface plus Vsync) -> not supported yet
+ * - Dotclock interface (to drive LC displays with RGB data and sync signals)
+ * - DVI (to drive ITU-R BT656)  -> not supported yet
+ *
+ * This driver depends on a correct setup of the pins used for this purpose
+ * (platform specific).
+ *
+ * For the developer: Don't forget to set the data bus width to the display
+ * in the imx_fb_videomode structure. You will else end up with ugly colours.
+ * If you fight against jitter you can vary the clock delay. This is a feature
+ * of the i.MX28 and you can vary it between 2 ns ... 8 ns in 2 ns steps. Give
+ * the required value in the imx_fb_videomode structure.

+/*
+ * This driver exists to allow userspace programs in Linux to allocate kernel
+ * memory that will later be shared with another domain.  Without this device,
+ * Linux userspace programs cannot create grant references.
+ *
+ * How this stuff works:
+ *   X -> granting a page to Y
+ *   Y -> mapping the grant from X
+ *
+ *   1. X uses the gntalloc device to allocate a page of kernel memory, P.
+ *   2. X creates an entry in the grant table that says domid(Y) can access P.
+ *      This is done without a hypercall unless the grant table needs expansion.
+ *   3. X gives the grant reference identifier, GREF, to Y.
+ *   4. Y maps the page, either directly into kernel memory for use in a backend
+ *      driver, or via a the gntdev device to map into the address space of an
+ *      application running in Y. This is the first point at which Xen does any
+ *      tracking of the page.
+ *   5. A program in X mmap()s a segment of the gntalloc device that corresponds
+ *      to the shared page, and can now communicate with Y over the shared page.
+ *
+ *
+ * NOTE TO USERSPACE LIBRARIES:
+ *   The grant allocation and mmap()ing are, naturally, two separate operations.
+ *   You set up the sharing by calling the create ioctl() and then the mmap().
+ *   Teardown requires munmap() and either close() or ioctl().
+ *
+ * WARNING: Since Xen does not allow a guest to forcibly end the use of a grant
+ * reference, this device can be used to consume kernel memory by leaving grant
+ * references mapped by another domain when an application exits. Therefore,
+ * there is a global limit on the number of pages that can be allocated. When
+ * all references to the page are unmapped, it will be freed during the next
+ * grant operation.
