+Description
+
+  DRBD is a shared-nothing, synchronously replicated block device. It
+  is designed to serve as a building block for high availability
+  clusters and in this context, is a "drop-in" replacement for shared
+  storage. Simplistically, you could see it as a network RAID 1.
+
+  Please visit http://www.drbd.org to find out more.
+
+The here included files are intended to help understand the implementation
+
+DRBD-8.3-data-packets.svg, DRBD-data-packets.svg  
+  relates some functions, and write packets.
+
+conn-states-8.dot, disk-states-8.dot, node-states-8.dot
+  The sub graphs of DRBD's state transitions

+				Block IO Controller
+				===================
+Overview
+========
+cgroup subsys "blkio" implements the block io controller. There seems to be
+a need of various kinds of IO control policies (like proportional BW, max BW)
+both at leaf nodes as well as at intermediate nodes in a storage hierarchy.
+Plan is to use the same cgroup based management interface for blkio controller
+and based on user options switch IO policies in the background.
+
+In the first phase, this patchset implements proportional weight time based
+division of disk policy. It is implemented in CFQ. Hence this policy takes
+effect only on leaf nodes when CFQ is being used.
+
+HOWTO
+=====
+You can do a very simple testing of running two dd threads in two different
+cgroups. Here is what you can do.
+
+- Enable group scheduling in CFQ
+	CONFIG_CFQ_GROUP_IOSCHED=y
+
+- Compile and boot into kernel and mount IO controller (blkio).
+
+	mount -t cgroup -o blkio none /cgroup
+
+- Create two cgroups
+	mkdir -p /cgroup/test1/ /cgroup/test2
+
+- Set weights of group test1 and test2
+	echo 1000 > /cgroup/test1/blkio.weight
+	echo 500 > /cgroup/test2/blkio.weight
+
+- Create two same size files (say 512MB each) on same disk (file1, file2) and
+  launch two dd threads in different cgroup to read those files.
+
+	sync
+	echo 3 > /proc/sys/vm/drop_caches
+
+	dd if=/mnt/sdb/zerofile1 of=/dev/null &
+	echo $! > /cgroup/test1/tasks
+	cat /cgroup/test1/tasks
+
+	dd if=/mnt/sdb/zerofile2 of=/dev/null &
+	echo $! > /cgroup/test2/tasks
+	cat /cgroup/test2/tasks
+
+- At macro level, first dd should finish first. To get more precise data, keep
+  on looking at (with the help of script), at blkio.disk_time and
+  blkio.disk_sectors files of both test1 and test2 groups. This will tell how
+  much disk time (in milli seconds), each group got and how many secotors each
+  group dispatched to the disk. We provide fairness in terms of disk time, so
+  ideally io.disk_time of cgroups should be in proportion to the weight.
+
+Various user visible config options
+===================================
+CONFIG_CFQ_GROUP_IOSCHED
+	- Enables group scheduling in CFQ. Currently only 1 level of group
+	  creation is allowed.
+
+CONFIG_DEBUG_CFQ_IOSCHED
+	- Enables some debugging messages in blktrace. Also creates extra
+	  cgroup file blkio.dequeue.
+
+Config options selected automatically
+=====================================
+These config options are not user visible and are selected/deselected
+automatically based on IO scheduler configuration.
+
+CONFIG_BLK_CGROUP
+	- Block IO controller. Selected by CONFIG_CFQ_GROUP_IOSCHED.
+
+CONFIG_DEBUG_BLK_CGROUP
+	- Debug help. Selected by CONFIG_DEBUG_CFQ_IOSCHED.
+
+Details of cgroup files
+=======================
+- blkio.weight
+	- Specifies per cgroup weight.
+
+	  Currently allowed range of weights is from 100 to 1000.
+
+- blkio.time
+	- disk time allocated to cgroup per device in milliseconds. First
+	  two fields specify the major and minor number of the device and
+	  third field specifies the disk time allocated to group in
+	  milliseconds.
+
+- blkio.sectors
+	- number of sectors transferred to/from disk by the group. First
+	  two fields specify the major and minor number of the device and
+	  third field specifies the number of sectors transferred by the
+	  group to/from the device.
+
+- blkio.dequeue
+	- Debugging aid only enabled if CONFIG_DEBUG_CFQ_IOSCHED=y. This
+	  gives the statistics about how many a times a group was dequeued
+	  from service tree of the device. First two fields specify the major
+	  and minor number of the device and third field specifies the number
+	  of times a group was dequeued from a particular device.
+
+CFQ sysfs tunable
+=================
+/sys/block/<disk>/queue/iosched/group_isolation
+
+If group_isolation=1, it provides stronger isolation between groups at the
+expense of throughput. By default group_isolation is 0. In general that
+means that if group_isolation=0, expect fairness for sequential workload
+only. Set group_isolation=1 to see fairness for random IO workload also.
+
+Generally CFQ will put random seeky workload in sync-noidle category. CFQ
+will disable idling on these queues and it does a collective idling on group
+of such queues. Generally these are slow moving queues and if there is a
+sync-noidle service tree in each group, that group gets exclusive access to
+disk for certain period. That means it will bring the throughput down if
+group does not have enough IO to drive deeper queue depths and utilize disk
+capacity to the fullest in the slice allocated to it. But the flip side is
+that even a random reader should get better latencies and overall throughput
+if there are lots of sequential readers/sync-idle workload running in the
+system.
+
+If group_isolation=0, then CFQ automatically moves all the random seeky queues
+in the root group. That means there will be no service differentiation for
+that kind of workload. This leads to better throughput as we do collective
+idling on root sync-noidle tree.
+
+By default one should run with group_isolation=0. If that is not sufficient
+and one wants stronger isolation between groups, then set group_isolation=1
+but this will come at cost of reduced throughput.
+
+What works
+==========
+- Currently only sync IO queues are support. All the buffered writes are
+  still system wide and not per group. Hence we will not see service
+  differentiation between buffered writes between groups.

-
-Description
------------
-
-The 3dfx Voodoo3 chip contains two I2C interfaces (aka a I2C 'master' or
-'host'). 
-
-The first interface is used for DDC (Data Display Channel) which is a
-serial channel through the VGA monitor connector to a DDC-compliant
-monitor. This interface is defined by the Video Electronics Standards
-Association (VESA). The standards are available for purchase at
-http://www.vesa.org .
-
-The second interface is a general-purpose I2C bus. The intent by 3dfx was
-to allow manufacturers to add extra chips to the video card such as a
-TV-out chip such as the BT869 or possibly even I2C based temperature
-sensors like the ADM1021 or LM75.
-
-Stability
----------
-
-Seems to be stable on the test machine, but needs more testing on other
-machines. Simultaneous accesses of the DDC and I2C busses may cause errors.
-
-Supported Devices
------------------
-
-Specifically, this driver was written and tested on the '3dfx Voodoo3 AGP
-3000' which has a tv-out feature (s-video or composite).  According to the
-docs and discussions, this code should work for any Voodoo3 based cards as
-well as Voodoo Banshee based cards.  The DDC interface has been tested on a
-Voodoo Banshee card.

-Issues
-------
-
-Probably many, but it seems to work OK on my system. :')
-
-
-External Device Connection
---------------------------
-
-The digital video input jumpers give availability to the I2C bus. 
-Specifically, pins 13 and 25 (bottom row middle, and bottom right-end) are     
-the I2C clock and I2C data lines, respectively. +5V and GND are probably
-also easily available making the addition of extra I2C/SMBus devices easy
-to implement.

+I2C device driver binding control from user-space
+=================================================
+
+Up to kernel 2.6.32, many i2c drivers used helper macros provided by
+<linux/i2c.h> which created standard module parameters to let the user
+control how the driver would probe i2c buses and attach to devices. These
+parameters were known as "probe" (to let the driver probe for an extra
+address), "force" (to forcibly attach the driver to a given device) and
+"ignore" (to prevent a driver from probing a given address).
+
+With the conversion of the i2c subsystem to the standard device driver
+binding model, it became clear that these per-module parameters were no
+longer needed, and that a centralized implementation was possible. The new,
+sysfs-based interface is described in the documentation file
+"instantiating-devices", section "Method 4: Instantiate from user-space".
+
+Below is a mapping from the old module parameters to the new interface.
+
+Attaching a driver to an I2C device
+-----------------------------------
+
+Old method (module parameters):
+# modprobe <driver> probe=1,0x2d
+# modprobe <driver> force=1,0x2d
+# modprobe <driver> force_<device>=1,0x2d
+
+New method (sysfs interface):
+# echo <device> 0x2d > /sys/bus/i2c/devices/i2c-1/new_device
+
+Preventing a driver from attaching to an I2C device
+---------------------------------------------------
+
+Old method (module parameters):
+# modprobe <driver> ignore=1,0x2f
+
+New method (sysfs interface):
+# echo dummy 0x2f > /sys/bus/i2c/devices/i2c-1/new_device
+# modprobe <driver>
+
+Of course, it is important to instantiate the "dummy" device before loading
+the driver. The dummy device will be handled by i2c-core itself, preventing
+other drivers from binding to it later on. If there is a real device at the
+problematic address, and you want another driver to bind to it, then simply
+pass the name of the device in question instead of "dummy".

+ * Neuros Technologies OSD2 board support
+ *
+ * Modified from original 644X-EVM board support.
+ * 2008 (c) Neuros Technology, LLC.
+ * 2009 (c) Jorge Luis Zapata Muga <jorgeluis.zapata@gmail.com>
+ * 2009 (c) Andrey A. Porodko <Andrey.Porodko@gmail.com>
+ *
+ * The Neuros OSD 2.0 is the hardware component of the Neuros Open
+ * Internet Television Platform. Hardware is very close to TI
+ * DM644X-EVM board. It has:
+ * 	DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC,
+ * 	USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video.
+ * 	Additionaly realtime clock, IR remote control receiver,
+ * 	IR Blaster based on MSP430 (firmware although is different
+ * 	from used in DM644X-EVM), internal ATA-6 3.5” HDD drive
+ * 	with PATA interface, two muxed red-green leds.
+ *
+ * For more information please refer to
+ * 		http://wiki.neurostechnology.com/index.php/OSD_2.0_HD

+ * The @gpio_detect is used for card detection when @no_wprotect is unset,
+ * and the default sense is that 0 returned from gpio_get_value() means
+ * that a card is inserted. If @detect_invert is set, then the value from
+ * gpio_get_value() is inverted, which makes 1 mean card inserted.
+ *
+ * The driver will use @gpio_wprotect to signal whether the card is write
+ * protected if @no_wprotect is not set. A 0 returned from gpio_get_value()
+ * means the card is read/write, and 1 means read-only. The @wprotect_invert
+ * will invert the value returned from gpio_get_value().
+ *
+ * Card power is set by @ocr_availa, using MCC_VDD_ constants if it is set
+ * to a non-zero value, otherwise the default of 3.2-3.4V is used.

-	  Enable this option if your platform does not have a CPU cache which

-	  will see better performance if you can say 'N', because the PCI DMA
-	  code will not have to flush the CPU's caches. If you have a PCI host
-	  bridge integrated with your SH CPU, refer carefully to the chip specs
-	  to see if you can say 'N' here. Otherwise, leave it as 'Y'.

- *
- * This also breaks in a number of circumstances:
- * - if there are modifications to the region of memory just above
- *   empty_zero_page (for example because a breakpoint has been placed

- *
- *   This is because the the memory address which the cache temporarily

- *   movca.l hits the cache (it is assumed that it misses, or at least
- *   isn't dirty), modifies the line and then invalidates it, losing the
- *   required change.
- *
- * - If caches are disabled or configured in write-through mode, then

- *	Event Code	Description
- *	----------	-----------
- *
- *	0x01		Operand read access

- *	0x0a		All instruction accesses
- *	0x0b		OC RAM operand access
- *	0x0d		On-chip I/O space access
- *	0x0e		Operand access (r/w)
- *	0x0f		Operand cache miss (r/w)
- *	0x10		Branch instruction
- *	0x11		Branch taken

- *	0x13		Instruction execution
- *	0x14		Instruction execution in parallel
- *	0x15		FPU Instruction execution
- *	0x16		Interrupt
- *	0x17		NMI
- *	0x18		trapa instruction execution
- *	0x19		UBCA match
- *	0x1a		UBCB match
- *	0x21		Instruction cache fill
- *	0x22		Operand cache fill
- *	0x23		Elapsed time
- *	0x24		Pipeline freeze by I-cache miss
- *	0x25		Pipeline freeze by D-cache miss
- *	0x27		Pipeline freeze by branch instruction
- *	0x28		Pipeline freeze by CPU register
- *	0x29		Pipeline freeze by FPU
- *
- * Unfortunately we don't have a native exception or interrupt for counter
- * overflow (although since these counters can run for 16.3 days without

+
+	  NOTE: In order to authenticate connections you have to select
+	  CRYPTO_HMAC and a hash function as well.
+
+	  DRBD is a shared-nothing, synchronously replicated block device. It
+	  is designed to serve as a building block for high availability
+	  clusters and in this context, is a "drop-in" replacement for shared
+	  storage. Simplistically, you could see it as a network RAID 1.
+
+	  Each minor device has a role, which can be 'primary' or 'secondary'.
+	  On the node with the primary device the application is supposed to
+	  run and to access the device (/dev/drbdX). Every write is sent to
+	  the local 'lower level block device' and, across the network, to the
+	  node with the device in 'secondary' state.  The secondary device
+	  simply writes the data to its lower level block device.
+
+	  DRBD can also be used in dual-Primary mode (device writable on both
+	  nodes), which means it can exhibit shared disk semantics in a
+	  shared-nothing cluster.  Needless to say, on top of dual-Primary
+	  DRBD utilizing a cluster file system is necessary to maintain for
+	  cache coherency.
+
+	  For automatic failover you need a cluster manager (e.g. heartbeat).
+	  See also: http://www.drbd.org/, http://www.linux-ha.org

+ * The _NS macros are used for state functions that get called with the

+ *
+ * E.g. NS2(conn, C_CONNECTED, peer, R_SECONDARY)

+ * At a granularity of 4KiB storage represented per bit,
+ * and stroage sizes of several TiB,
+ * and possibly small-bandwidth replication,
+ * the bitmap transfer time can take much too long,
+ * if transmitted in plain text.
+ *
+ * We try to reduce the transfered bitmap information
+ * by encoding runlengths of bit polarity.
+ *
+ * We never actually need to encode a "zero" (runlengths are positive).
+ * But then we have to store the value of the first bit.
+ * The first bit of information thus shall encode if the first runlength
+ * gives the number of set or unset bits.
+ *
+ * We assume that large areas are either completely set or unset,
+ * which gives good compression with any runlength method,
+ * even when encoding the runlength as fixed size 32bit/64bit integers.
+ *
+ * Still, there may be areas where the polarity flips every few bits,
+ * and encoding the runlength sequence of those areas with fix size
+ * integers would be much worse than plaintext.
+ *
+ * We want to encode small runlength values with minimum code length,
+ * while still being able to encode a Huge run of all zeros.
+ *
+ * Thus we need a Variable Length Integer encoding, VLI.
+ *
+ * For some cases, we produce more code bits than plaintext input.
+ * We need to send incompressible chunks as plaintext, skip over them
+ * and then see if the next chunk compresses better.
+ *
+ * We don't care too much about "excellent" compression ratio for large
+ * runlengths (all set/all clear): whether we achieve a factor of 100
+ * or 1000 is not that much of an issue.
+ * We do not want to waste too much on short runlengths in the "noisy"
+ * parts of the bitmap, though.
+ *
+ * There are endless variants of VLI, we experimented with:
+ *  * simple byte-based
+ *  * various bit based with different code word length.
+ *
+ * To avoid yet an other configuration parameter (choice of bitmap compression
+ * algorithm) which was difficult to explain and tune, we just chose the one
+ * variant that turned out best in all test cases.
+ * Based on real world usage patterns, with device sizes ranging from a few GiB
+ * to several TiB, file server/mailserver/webserver/mysql/postgress,
+ * mostly idle to really busy, the all time winner (though sometimes only
+ * marginally better) is:

+ * encoding is "visualised" as

+ *
+ * this particular encoding is chosen so that the prefix code
+ * starts as unary encoding the level, then modified so that
+ * 10 levels can be described in 8bit, with minimal overhead
+ * for the smaller levels.
+ *
+ * Number of data bits follow fibonacci sequence, with the exception of the
+ * last level (+1 data bit, so it makes 64bit total).  The only worse code when
+ * encoding bit polarity runlength is 1 plain bits => 2 code bits.

- *
- * Falcon hardware access
- *
- **************************************************************************
- *
- * Notes on locking strategy:
- *
- * Most Falcon registers require 16-byte (or 8-byte, for SRAM
- * registers) atomic writes which necessitates locking.
- * Under normal operation few writes to the Falcon BAR are made and these
- * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
- * cased to allow 4-byte (hence lockless) accesses.
- *
- * It *is* safe to write to these 4-byte registers in the middle of an
- * access to an 8-byte or 16-byte register.  We therefore use a
- * spinlock to protect accesses to the larger registers, but no locks
- * for the 4-byte registers.
- *
- * A write barrier is needed to ensure that DW3 is written after DW0/1/2
- * due to the way the 16byte registers are "collected" in the Falcon BIU
- *
- * We also lock when carrying out reads, to ensure consistency of the
- * data (made possible since the BIU reads all 128 bits into a cache).
- * Reads are very rare, so this isn't a significant performance
- * impact.  (Most data transferred from NIC to host is DMAed directly
- * into host memory).
- *
- * I/O BAR access uses locks for both reads and writes (but is only provided
- * for testing purposes).

+ **************************************************************************
+ *
+ * Notes on locking strategy:
+ *
+ * Most NIC registers require 16-byte (or 8-byte, for SRAM) atomic writes
+ * which necessitates locking.
+ * Under normal operation few writes to NIC registers are made and these
+ * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special
+ * cased to allow 4-byte (hence lockless) accesses.
+ *
+ * It *is* safe to write to these 4-byte registers in the middle of an
+ * access to an 8-byte or 16-byte register.  We therefore use a
+ * spinlock to protect accesses to the larger registers, but no locks
+ * for the 4-byte registers.
+ *
+ * A write barrier is needed to ensure that DW3 is written after DW0/1/2
+ * due to the way the 16byte registers are "collected" in the BIU.
+ *
+ * We also lock when carrying out reads, to ensure consistency of the

+ *   - To complete a shared memory request if XFLAGS_EVREQ was set
+ *   - As a notification (link state, i2c event), controlled
+ *     via MC_CMD_LOG_CTRL
+ *
+ * Both events share a common structure:
+ *
+ *  0      32     33      36    44     52     60
+ * | Data | Cont | Level | Src | Code | Rsvd |
+ *           |
+ *           \ There is another event pending in this notification
+ *
+ * If Code==CMDDONE, then the fields are further interpreted as:
+ *
+ *   - LEVEL==INFO    Command succeded
+ *   - LEVEL==ERR     Command failed
+ *
+ *    0     8         16      24     32
+ *   | Seq | Datalen | Errno | Rsvd |
+ *
+ *   These fields are taken directly out of the standard MCDI header, i.e.,
+ *   LEVEL==ERR, Datalen == 0 => Reboot
+ *
+ * Events can be squirted out of the UART (using LOG_CTRL) without a
+ * MCDI header.  An event can be distinguished from a MCDI response by
+ * examining the first byte which is 0xc0.  This corresponds to the
+ * non-existent MCDI command MC_CMD_DEBUG_LOG.
+ *
+ *      0         7        8
+ *     | command | Resync |     = 0xc0
+ *
+ * Since the event is written in big-endian byte order, this works
+ * providing bits 56-63 of the event are 0xc0.
+ *
+ *      56     60  63
+ *     | Rsvd | Code |    = 0xc0
+ *
+ * Which means for convenience the event code is 0xc for all MC
+ * generated events.

- * @i2400m: device descriptor
- *
- * @fn: function to run to execute work. It gets passed a 'struct
- *     work_struct' that is wrapped in a 'struct i2400m_work'. Once
- *     done, you have to (1) i2400m_put(i2400m_work->i2400m) and then
- *     (2) kfree(i2400m_work).
- *
- * @gfp_flags: GFP flags for memory allocation.
- *
- * @pl: pointer to a payload buffer that you want to pass to the _work
- *     function. Use this to pack (for example) a struct with extra
- *     arguments.
- *
- * @pl_size: size of the payload buffer.
- *
- * We do this quite often, so this just saves typing; allocate a
- * wrapper for a i2400m, get a ref to it, pack arguments and launch
- * the work.
- *
- * A usual workflow is:
- *
- * struct my_work_args {
- *         void *something;
- *         int whatever;
- * };
- * ...
- *

- *                   &args, sizeof(args))
- *
- * And now the work function can unpack the arguments and call the
- * real function (or do the job itself):
- *
- * static
- * void my_work_fn((struct work_struct *ws)
- * {

-/**
- * ath5k_hw_set_bssid_mask - filter out bssids we listen
- *
- * @ah: the &struct ath5k_hw
- * @mask: the bssid_mask, a u8 array of size ETH_ALEN
- *
- * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
- * which bits of the interface's MAC address should be looked at when trying
- * to decide which packets to ACK. In station mode and AP mode with a single
- * BSS every bit matters since we lock to only one BSS. In AP mode with
- * multiple BSSes (virtual interfaces) not every bit matters because hw must
- * accept frames for all BSSes and so we tweak some bits of our mac address
- * in order to have multiple BSSes.
- *
- * NOTE: This is a simple filter and does *not* filter out all
- * relevant frames. Some frames that are not for us might get ACKed from us
- * by PCU because they just match the mask.
- *
- * When handling multiple BSSes you can get the BSSID mask by computing the
- * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
- *
- * When you do this you are essentially computing the common bits of all your
- * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
- * the MAC address to obtain the relevant bits and compare the result with
- * (frame's BSSID & mask) to see if they match.
- */
-/*
- * Simple example: on your card you have have two BSSes you have created with
- * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
- * There is another BSSID-03 but you are not part of it. For simplicity's sake,
- * assuming only 4 bits for a mac address and for BSSIDs you can then have:
- *
- *                  \
- * MAC:                0001 |
- * BSSID-01:   0100 | --> Belongs to us
- * BSSID-02:   1001 |
- *                  /
- * -------------------
- * BSSID-03:   0110  | --> External
- * -------------------
- *
- * Our bssid_mask would then be:
- *
- *             On loop iteration for BSSID-01:
- *             ~(0001 ^ 0100)  -> ~(0101)
- *                             ->   1010
- *             bssid_mask      =    1010
- *
- *             On loop iteration for BSSID-02:
- *             bssid_mask &= ~(0001   ^   1001)
- *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
- *             bssid_mask =   (1010)  & ~(1001)
- *             bssid_mask =   (1010)  &  (0110)
- *             bssid_mask =   0010
- *
- * A bssid_mask of 0010 means "only pay attention to the second least
- * significant bit". This is because its the only bit common
- * amongst the MAC and all BSSIDs we support. To findout what the real
- * common bit is we can simply "&" the bssid_mask now with any BSSID we have
- * or our MAC address (we assume the hardware uses the MAC address).
- *
- * Now, suppose there's an incoming frame for BSSID-03:
- *
- * IFRAME-01:  0110
- *
- * An easy eye-inspeciton of this already should tell you that this frame
- * will not pass our check. This is beacuse the bssid_mask tells the
- * hardware to only look at the second least significant bit and the
- * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
- * as 1, which does not match 0.
- *
- * So with IFRAME-01 we *assume* the hardware will do:
- *
- *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
- *  --> allow = (0010) == 0000 ? 1 : 0;
- *  --> allow = 0
- *
- *  Lets now test a frame that should work:
- *
- * IFRAME-02:  0001 (we should allow)
- *
- *     allow = (0001 & 1010) == 1010
- *
- *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
- *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
- *  --> allow = (0010) == (0010)
- *  --> allow = 1
- *
- * Other examples:
- *
- * IFRAME-03:  0100 --> allowed
- * IFRAME-04:  1001 --> allowed
- * IFRAME-05:  1101 --> allowed but its not for us!!!

+ * ath9k_hw_updatetxtriglevel - adjusts the frame trigger level
+ *
+ * @ah: atheros hardware struct
+ * @bIncTrigLevel: whether or not the frame trigger level should be updated
+ *
+ * The frame trigger level specifies the minimum number of bytes,
+ * in units of 64 bytes, that must be DMA'ed into the PCU TX FIFO
+ * before the PCU will initiate sending the frame on the air. This can
+ * mean we initiate transmit before a full frame is on the PCU TX FIFO.
+ * Resets to 0x1 (meaning 64 bytes or a full frame, whichever occurs
+ * first)
+ *
+ * Caution must be taken to ensure to set the frame trigger level based
+ * on the DMA request size. For example if the DMA request size is set to
+ * 128 bytes the trigger level cannot exceed 6 * 64 = 384. This is because
+ * there need to be enough space in the tx FIFO for the requested transfer
+ * size. Hence the tx FIFO will stop with 512 - 128 = 384 bytes. If we set
+ * the threshold to a value beyond 6, then the transmit will hang.
+ *
+ * Current dual   stream devices have a PCU TX FIFO size of 8 KB.
+ * Current single stream devices have a PCU TX FIFO size of 4 KB, however,
+ * there is a hardware issue which forces us to use 2 KB instead so the
+ * frame trigger level must not exceed 2 KB for these chipsets.

+/**
+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:        0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+IWCONFIG COMMANDS
+========================
+power period
+
+	This command is used to configure the station in deep sleep mode /
+	auto deep sleep mode.
+
+	The timer is implemented to monitor the activities (command, event,
+	etc.). When an activity is detected station will exit from deep
+	sleep mode automatically and restart the timer. At timer expiry
+	(no activity for defined time period) the deep sleep mode is entered
+	automatically.
+
+	Note: this command is for SDIO interface only.
+
+	Usage:
+	To enable deep sleep mode do:
+		iwconfig wlan0 power period 0
+	To enable auto deep sleep mode with idle time period 5 seconds do:
+		iwconfig wlan0 power period 5
+	To disable deep sleep/auto deep sleep mode do:
+		iwconfig wlan0 power period -1

+	tristate "Aironet Arlan 655 & IC2200 DS support"
+	depends on ISA && !64BIT && WLAN
+	select WIRELESS_EXT
+	---help---
+	  Aironet makes Arlan, a class of wireless LAN adapters. These use the
+	  www.Telxon.com chip, which is also used on several similar cards.
+	  This driver is tested on the 655 and IC2200 series cards. Look at
+	  <http://www.ylenurme.ee/~elmer/655/> for the latest information.
+
+	  The driver is built as two modules, arlan and arlan-proc. The latter
+	  is the /proc interface and is not needed most of time.
+
+	  On some computers the card ends up in non-valid state after some
+	  time. Use a ping-reset script to clear it.

+TODO:
+	- step up and maintain this driver to ensure that it continues

+	  Say Y if you have a Metricom radio and intend to use Starmode Radio
+	  IP. STRIP is a radio protocol developed for the MosquitoNet project
+	  to send Internet traffic using Metricom radios.  Metricom radios are
+	  small, battery powered, 100kbit/sec packet radio transceivers, about
+	  the size and weight of a cellular telephone. (You may also have heard
+	  them called "Metricom modems" but we avoid the term "modem" because
+	  it misleads many people into thinking that you can plug a Metricom
+	  modem into a phone line and use it as a modem.)
+
+	  You can use STRIP on any Linux machine with a serial port, although
+	  it is obviously most useful for people with laptop computers. If you
+	  think you might get a Metricom radio in the future, there is no harm
+	  in saying Y to STRIP now, except that it makes the kernel a bit
+	  bigger.
+
+	  To compile this as a module, choose M here: the module will be

+This header file (and its .c file; kernel-doc of functions see there)
+  define a helper framework to easily keep track of index:label associations,
+  and changes to an "active set" of objects, as well as pending transactions,
+  to persistently record those changes.
+
+  We use an LRU policy if it is necessary to "cool down" a region currently in
+  the active set before we can "heat" a previously unused region.
+
+  Because of this later property, it is called "lru_cache".
+  As it actually Tracks Objects in an Active SeT, we could also call it
+  toast (incidentally that is what may happen to the data on the
+  backend storage uppon next resync, if we don't get it right).
+
+What for?
+
+We replicate IO (more or less synchronously) to local and remote disk.
+
+For crash recovery after replication node failure,
+  we need to resync all regions that have been target of in-flight WRITE IO
+  (in use, or "hot", regions), as we don't know wether or not those WRITEs have
+  made it to stable storage.
+
+  To avoid a "full resync", we need to persistently track these regions.
+
+  This is known as "write intent log", and can be implemented as on-disk
+  (coarse or fine grained) bitmap, or other meta data.
+
+  To avoid the overhead of frequent extra writes to this meta data area,
+  usually the condition is softened to regions that _may_ have been target of
+  in-flight WRITE IO, e.g. by only lazily clearing the on-disk write-intent
+  bitmap, trading frequency of meta data transactions against amount of
+  (possibly unneccessary) resync traffic.
+
+  If we set a hard limit on the area that may be "hot" at any given time, we
+  limit the amount of resync traffic needed for crash recovery.
+
+For recovery after replication link failure,
+  we need to resync all blocks that have been changed on the other replica
+  in the mean time, or, if both replica have been changed independently [*],
+  all blocks that have been changed on either replica in the mean time.
+  [*] usually as a result of a cluster split-brain and insufficient protection.
+      but there are valid use cases to do this on purpose.
+
+  Tracking those blocks can be implemented as "dirty bitmap".
+  Having it fine-grained reduces the amount of resync traffic.
+  It should also be persistent, to allow for reboots (or crashes)
+  while the replication link is down.
+
+There are various possible implementations for persistently storing
+write intent log information, three of which are mentioned here.
+
+"Chunk dirtying"
+  The on-disk "dirty bitmap" may be re-used as "write-intent" bitmap as well.
+  To reduce the frequency of bitmap updates for write-intent log purposes,
+  one could dirty "chunks" (of some size) at a time of the (fine grained)
+  on-disk bitmap, while keeping the in-memory "dirty" bitmap as clean as
+  possible, flushing it to disk again when a previously "hot" (and on-disk
+  dirtied as full chunk) area "cools down" again (no IO in flight anymore,
+  and none expected in the near future either).
+
+"Explicit (coarse) write intent bitmap"
+  An other implementation could chose a (probably coarse) explicit bitmap,
+  for write-intent log purposes, additionally to the fine grained dirty bitmap.
+
+"Activity log"
+  Yet an other implementation may keep track of the hot regions, by starting
+  with an empty set, and writing down a journal of region numbers that have
+  become "hot", or have "cooled down" again.
+
+  To be able to use a ring buffer for this journal of changes to the active
+  set, we not only record the actual changes to that set, but also record the
+  not changing members of the set in a round robin fashion. To do so, we use a
+  fixed (but configurable) number of slots which we can identify by index, and
+  associate region numbers (labels) with these indices.
+  For each transaction recording a change to the active set, we record the
+  change itself (index: -old_label, +new_label), and which index is associated
+  with which label (index: current_label) within a certain sliding window that
+  is moved further over the available indices with each such transaction.
+
+  Thus, for crash recovery, if the ringbuffer is sufficiently large, we can
+  accurately reconstruct the active set.
+
+  Sufficiently large depends only on maximum number of active objects, and the
+  size of the sliding window recording "index: current_label" associations within
+  each transaction.
+
+  This is what we call the "activity log".
+
+  Currently we need one activity log transaction per single label change, which
+  does not give much benefit over the "dirty chunks of bitmap" approach, other
+  than potentially less seeks.
+
+  We plan to change the transaction format to support multiple changes per
+  transaction, which then would reduce several (disjoint, "random") updates to
+  the bitmap into one transaction to the activity log ring buffer.

+/* this defines an element in a tracked set
+ * .colision is for hash table lookup.
+ * When we process a new IO request, we know its sector, thus can deduce the
+ * region number (label) easily.  To do the label -> object lookup without a
+ * full list walk, we use a simple hash table.
+ *
+ * .list is on one of three lists:
+ *  in_use: currently in use (refcnt > 0, lc_number != LC_FREE)
+ *     lru: unused but ready to be reused or recycled
+ *          (ts_refcnt == 0, lc_number != LC_FREE),
+ *    free: unused but ready to be recycled
+ *          (ts_refcnt == 0, lc_number == LC_FREE),
+ *
+ * an element is said to be "in the active set",
+ * if either on "in_use" or "lru", i.e. lc_number != LC_FREE.
+ *
+ * DRBD currently (May 2009) only uses 61 elements on the resync lru_cache
+ * (total memory usage 2 pages), and up to 3833 elements on the act_log
+ * lru_cache, totalling ~215 kB for 64bit architechture, ~53 pages.
+ *
+ * We usually do not actually free these objects again, but only "recycle"
+ * them, as the change "index: -old_label, +LC_FREE" would need a transaction
+ * as well.  Which also means that using a kmem_cache to allocate the objects
+ * from wastes some resources.
+ * But it avoids high order page allocations in kmalloc.

-	 *	internally.
-	 *
-	 *	To fix this, we should send the frame through TX processing
-	 *	again. However, it's not that simple, since the frame will
-	 *	have been software-encrypted (if applicable) already, and
-	 *	encrypting it again doesn't do much good. So to properly do
-	 *	that, we not only have to skip the actual 'raw' encryption
-	 *	(key selection etc. still has to be done!) but also the
-	 *	sequence number assignment since that impacts the crypto
-	 *	encapsulation, of course.

-	 * This is actually quite unlikely even when both those events are

+	 *
+	 *	To fix this, we should send the frame through TX processing

+	 *	have been software-encrypted (if applicable) already, and
+	 *	encrypting it again doesn't do much good. So to properly do

-/************************** DOCUMENTATION **************************/
-/*
- * API definition :
- * --------------
- * See <linux/wireless.h> for details of the APIs and the rest.
- *
- * History :
- * -------
- *
- * v1 - 5.12.01 - Jean II
- *	o Created this file.
- *
- * v2 - 13.12.01 - Jean II
- *	o Move /proc/net/wireless stuff from net/core/dev.c to here
- *	o Make Wireless Extension IOCTLs go through here
- *	o Added iw_handler handling ;-)
- *	o Added standard ioctl description
- *	o Initial dumb commit strategy based on orinoco.c
- *
- * v3 - 19.12.01 - Jean II
- *	o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
- *	o Add event dispatcher function
- *	o Add event description
- *	o Propagate events as rtnetlink IFLA_WIRELESS option
- *	o Generate event on selected SET requests
- *
- * v4 - 18.04.02 - Jean II
- *	o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
- *
- * v5 - 21.06.02 - Jean II
- *	o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
- *	o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
- *	o Add IWEVCUSTOM for driver specific event/scanning token
- *	o Turn on WE_STRICT_WRITE by default + kernel warning
- *	o Fix WE_STRICT_WRITE in ioctl_export_private() (32 => iw_num)
- *	o Fix off-by-one in test (extra_size <= IFNAMSIZ)
- *
- * v6 - 9.01.03 - Jean II
- *	o Add common spy support : iw_handler_set_spy(), wireless_spy_update()
- *	o Add enhanced spy support : iw_handler_set_thrspy() and event.
- *	o Add WIRELESS_EXT version display in /proc/net/wireless
- *
- * v6 - 18.06.04 - Jean II
- *	o Change get_spydata() method for added safety
- *	o Remove spy #ifdef, they are always on -> cleaner code
- *	o Allow any size GET request if user specifies length > max
- *		and if request has IW_DESCR_FLAG_NOMAX flag or is SIOCGIWPRIV
- *	o Start migrating get_wireless_stats to struct iw_handler_def
- *	o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
- * Based on patch from Pavel Roskin <proski@gnu.org> :
- *	o Fix kernel data leak to user space in private handler handling
- *
- * v7 - 18.3.05 - Jean II
- *	o Remove (struct iw_point *)->pointer from events and streams
- *	o Remove spy_offset from struct iw_handler_def
- *	o Start deprecating dev->get_wireless_stats, output a warning
- *	o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
- *	o Don't lose INVALID/DBM flags when clearing UPDATED flags (iwstats)
- *
- * v8 - 17.02.06 - Jean II
- *	o RtNetlink requests support (SET/GET)
- *
- * v8b - 03.08.06 - Herbert Xu
- *	o Fix Wireless Event locking issues.
- *
- * v9 - 14.3.06 - Jean II
- *	o Change length in ESSID and NICK to strlen() instead of strlen()+1
- *	o Make standard_ioctl_num and standard_event_num unsigned
- *	o Remove (struct net_device *)->get_wireless_stats()
- *
- * v10 - 16.3.07 - Jean II
- *	o Prevent leaking of kernel space in stream on 64 bits.
