+
+ This driver uses the kernel's mac80211 subsystem.
+
+ In order to use this driver, you will need a firmware
+ image for it. You can obtain the microcode from:
+
+ <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.
+
+ The firmware is typically installed in /lib/firmware. You can
+ look in the hotplug script /etc/hotplug/firmware.agent to
+ determine which directory FIRMWARE_DIR is set to when the script
+ runs.
+
+ If you want to compile the driver as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want),
+ say M here and read <file:Documentation/kbuild/modules.txt>. The
+ module will be called iwlwifi.

+ depends on IWLMVM
+ help
+ Say Y here to enable default bcast filtering configuration.
+
+ Enabling broadcast filtering will drop any incoming wireless
+ broadcast frames, except some very specific predefined
+ patterns (e.g. incoming arp requests).
+
+ If unsure, don't enable this option, as some programs might
+ expect incoming broadcasts for their normal operations.
+
+config IWLWIFI_UAPSD
+ bool "enable U-APSD by default"
+ depends on IWLMVM
+ help
+ Say Y here to enable U-APSD by default. This may cause
+ interoperability problems with some APs, manifesting in lower than
+ expected throughput due to those APs not enabling aggregation
+
+ If unsure, say N.
+
+menu "Debugging Options"
+
+config IWLWIFI_DEBUG
+ bool "Enable full debugging output in the iwlwifi driver"
+ ---help---
+ This option will enable debug tracing output for the iwlwifi drivers
+
+ This will result in the kernel module being ~100k larger. You can
+ control which debug output is sent to the kernel log by setting the
+ value in
+
+ /sys/module/iwlwifi/parameters/debug
+
+ This entry will only exist if this option is enabled.
+
+ To set a value, simply echo an 8-byte hex value to the same file:
+
+ % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
+
+ You can find the list of debug mask values in:
+ drivers/net/wireless/iwlwifi/iwl-debug.h
+
+ If this is your first time using this driver, you should say Y here
+ as the debug information can assist others in helping you resolve
+ any problems you may encounter.
+
+config IWLWIFI_DEBUGFS
+ bool "iwlwifi debugfs support"
+ depends on MAC80211_DEBUGFS
+ ---help---
+ Enable creation of debugfs files for the iwlwifi drivers. This
+ is a low-impact option that allows getting insight into the
+ driver's state at runtime.
+
+config IWLWIFI_DEBUG_EXPERIMENTAL_UCODE
+ bool "Experimental uCode support"
+ depends on IWLWIFI_DEBUG
+ ---help---
+ Enable use of experimental ucode for testing and debugging.
+
+config IWLWIFI_DEVICE_TRACING
+ bool "iwlwifi device access tracing"
+ depends on EVENT_TRACING
+ default y
+ help
+ Say Y here to trace all commands, including TX frames and IO
+ accesses, sent to the device. If you say yes, iwlwifi will
+ register with the ftrace framework for event tracing and dump
+ all this information to the ringbuffer, you may need to
+ increase the ringbuffer size. See the ftrace documentation
+ for more information.
+
+ When tracing is not enabled, this option still has some
+ (though rather small) overhead.
+
+ If unsure, say Y so we can help you better when problems
+ occur.

+ *
+ * NOTE: Station must already be in agn device's station table.
+ * Use REPLY_ADD_STA.
+ *
+ * The rate scaling procedures described below work well. Of course, other
+ * procedures are possible, and may work better for particular environments.
+ *
+ *
+ * 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 agn 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 agn 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:
+ *
+ * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60
+ *
+ * G: 7 13 35 58 40 57 72 98 121 154 177 186 186

+ * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257
+ * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257

+ * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293
+ *
+ * After the new mode has been tried for a short while (minimum of 6 failed
+ * frames or 8 successful frames), compare success ratio and actual throughput
+ * estimate of the new mode with the old. If either is better with the new
+ * mode, continue to use the new mode.
+ *
+ * Continue comparing modes until all 3 possibilities have been tried.
+ * If moving from legacy to HT, try all 3 possibilities from the new HT
+ * mode. After trying all 3, a best mode is found. Continue to use this mode
+ * for the longer "while" described above (e.g. 480 successful frames for
+ * legacy), and then repeat the search process.

+ * 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.

+ * Rx Calibration Commands:
+ *
+ * With the uCode used for open source drivers, most Tx calibration (except

+ * "initialize" phase of uCode boot. Driver must calibrate only:
+ *

+ * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
+ * 3) Receiver sensitivity (to optimize signal detection)
+ *
+ *****************************************************************************/
+
+/**
+ * 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,
+ * down to min 125.
+ *
+ * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
+ * down to min 200.
+ *
+ * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
+ *
+ * If actual rate of CCK false alarms (+ plcp_errors) is within good range
+ * (between 5 and 50 for each 204.8 msecs listening):
+ *
+ * 1) Save a snapshot of the silence reference.
+ *
+ * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
+ * give some extra margin to energy threshold by *subtracting* 8
+ * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
+ *
+ * For all cases (too few, too many, good range), make sure that the CCK
+ * detection threshold (energy) is below the energy level for robust
+ * detection over the past 10 beacon periods, the "Max cck energy".
+ * Lower values mean higher energy; this means making sure that the value
+ * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

+ * REPLY_PHY_CALIBRATION_CMD = 0xb0 (command, has simple generic response)
+ *
+ * This command sets the relative gains of agn 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

+ * This component is also in charge of managing the several implementations of
+ * the wifi flows: it will allow to have several fw API implementation. These
+ * different implementations will differ in the way they implement mac80211's
+ * handlers too.
+
+ * The init flow wrt to the drv component looks like this:
+ * 1) The bus specific component is called from module_init
+ * 2) The bus specific component registers the bus driver
+ * 3) The bus driver calls the probe function
+ * 4) The bus specific component configures the bus
+ * 5) The bus specific component calls to the drv bus agnostic part
+ * (iwl_drv_start)
+ * 6) iwl_drv_start fetches the fw ASYNC, iwl_req_fw_callback
+ * 7) iwl_req_fw_callback parses the fw file
+ * 8) iwl_req_fw_callback starts the wifi implementation to matches the fw

+/**
+ * Rx SRAM Control and Status Registers (RSCSR)
+ *
+ * These registers provide handshake between driver and device for the Rx queue
+ * (this queue handles *all* command responses, notifications, Rx data, etc.
+ * sent from uCode to host driver). Unlike Tx, there is only one Rx
+ * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can
+ * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
+ * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
+ * mapping between RBDs and RBs.
+ *
+ * Driver must allocate host DRAM memory for the following, and set the
+ * physical address of each into device registers:
+ *
+ * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
+ * entries (although any power of 2, up to 4096, is selectable by driver).
+ * Each entry (1 dword) points to a receive buffer (RB) of consistent size
+ * (typically 4K, although 8K or 16K are also selectable by driver).
+ * Driver sets up RB size and number of RBDs in the CB via Rx config
+ * register FH_MEM_RCSR_CHNL0_CONFIG_REG.
+ *
+ * Bit fields within one RBD:
+ * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned
+ *
+ * Driver sets physical address [35:8] of base of RBD circular buffer
+ * into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
+ *
+ * 2) Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
+ * (RBs) have been filled, via a "write pointer", actually the index of
+ * the RB's corresponding RBD within the circular buffer. Driver sets
+ * physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
+ *
+ * Bit fields in lower dword of Rx status buffer (upper dword not used
+ * by driver:
+ * 31-12: Not used by driver
+ * 11- 0: Index of last filled Rx buffer descriptor
+ * (device writes, driver reads this value)
+ *
+ * As the driver prepares Receive Buffers (RBs) for device to fill, driver must
+ * enter pointers to these RBs into contiguous RBD circular buffer entries,
+ * and update the device'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: DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
+ *
+ * As the device 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 device
+ *
+ * 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, device 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.

+
+/**
+ * DOC: Life cycle of the Operational mode
+ *
+ * The operational mode has a very simple life cycle.
+ *
+ * 1) The driver layer (iwl-drv.c) chooses the op_mode based on the
+ * capabilities advertised by the fw file (in TLV format).
+ * 2) The driver layer starts the op_mode (ops->start)
+ * 3) The op_mode registers mac80211
+ * 4) The op_mode is governed by mac80211
+ * 5) The driver layer stops the op_mode
+ */
+
+/**
+ * struct iwl_op_mode_ops - op_mode specific operations
+ *
+ * The op_mode exports its ops so that external components can start it and
+ * interact with it. The driver layer typically calls the start and stop
+ * handlers, the transport layer calls the others.
+ *
+ * All the handlers MUST be implemented, except @rx_rss which can be left
+ * out *iff* the opmode will never run on hardware with multi-queue capability.
+ *
+ * @start: start the op_mode. The transport layer is already allocated.
+ * May sleep
+ * @stop: stop the op_mode. Must free all the memory allocated.
+ * May sleep
+ * @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
+ * HCMD this Rx responds to. Can't sleep.
+ * @rx_rss: data queue RX notification to the op_mode, for (data) notifications
+ * received on the RSS queue(s). The queue parameter indicates which of the
+ * RSS queues received this frame; it will always be non-zero.
+ * This method must not sleep.
+ * @queue_full: notifies that a HW queue is full.
+ * Must be atomic and called with BH disabled.
+ * @queue_not_full: notifies that a HW queue is not full any more.
+ * Must be atomic and called with BH disabled.
+ * @hw_rf_kill:notifies of a change in the HW rf kill switch. True means that
+ * the radio is killed. Return %true if the device should be stopped by
+ * the transport immediately after the call. May sleep.
+ * @free_skb: allows the transport layer to free skbs that haven't been
+ * reclaimed by the op_mode. This can happen when the driver is freed and
+ * there are Tx packets pending in the transport layer.
+ * Must be atomic
+ * @nic_error: error notification. Must be atomic and must be called with BH
+ * disabled.
+ * @cmd_queue_full: Called when the command queue gets full. Must be atomic and
+ * called with BH disabled.
+ * @nic_config: configure NIC, called before firmware is started.
+ * May sleep
+ * @wimax_active: invoked when WiMax becomes active. May sleep
+ * @enter_d0i3: configure the fw to enter d0i3. return 1 to indicate d0i3
+ * entrance is aborted (e.g. due to held reference). May sleep.

+/**
+ * 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 5000 series and up, they are used differently
+ * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.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 -- unused
+ * 5 -- unused
+ * 6 -- unused
+ * 7 -- Commands
+ *
+ * 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

+ * the SCD base address in SRAM, then provide it here, or 0 otherwise.
+ * May sleep
+ * @stop_device: stops the whole device (embedded CPU put to reset) and stops
+ * the HW. If low_power is true, the NIC will be put in low power state.
+ * From that point on, the HW will be stopped but will still issue an
+ * interrupt if the HW RF kill switch is triggered.
+ * This callback must do the right thing and not crash even if %start_hw()
+ * was called but not &start_fw(). May sleep.
+ * @d3_suspend: put the device into the correct mode for WoWLAN during
+ * suspend. This is optional, if not implemented WoWLAN will not be
+ * supported. This callback may sleep.
+ * @d3_resume: resume the device after WoWLAN, enabling the opmode to
+ * talk to the WoWLAN image to get its status. This is optional, if not
+ * implemented WoWLAN will not be supported. This callback may sleep.
+ * @send_cmd:send a host command. Must return -ERFKILL if RFkill is asserted.
+ * If RFkill is asserted in the middle of a SYNC host command, it must
+ * return -ERFKILL straight away.
+ * May sleep only if CMD_ASYNC is not set
+ * @tx: send an skb
+ * Must be atomic
+ * @reclaim: free packet until ssn. Returns a list of freed packets.
+ * Must be atomic
+ * @txq_enable: setup a queue. To setup an AC queue, use the
+ * iwl_trans_ac_txq_enable wrapper. fw_alive must have been called before
+ * this one. The op_mode must not configure the HCMD queue. The scheduler
+ * configuration may be %NULL, in which case the hardware will not be
+ * configured. May sleep.
+ * @txq_disable: de-configure a Tx queue to send AMPDUs
+ * Must be atomic
+ * @wait_tx_queue_empty: wait until tx queues are empty. May sleep.
+ * @freeze_txq_timer: prevents the timer of the queue from firing until the
+ * queue is set to awake. Must be atomic.
+ * @dbgfs_register: add the dbgfs files under this directory. Files will be
+ * automatically deleted.
+ * @write8: write a u8 to a register at offset ofs from the BAR
+ * @write32: write a u32 to a register at offset ofs from the BAR
+ * @read32: read a u32 register at offset ofs from the BAR
+ * @read_prph: read a DWORD from a periphery register
+ * @write_prph: write a DWORD to a periphery register
+ * @read_mem: read device's SRAM in DWORD
+ * @write_mem: write device's SRAM in DWORD. If %buf is %NULL, then the memory
+ * will be zeroed.
+ * @configure: configure parameters required by the transport layer from
+ * the op_mode. May be called several times before start_fw, can't be
+ * called after that.
+ * @set_pmi: set the power pmi state
+ * @grab_nic_access: wake the NIC to be able to access non-HBUS regs.
+ * Sleeping is not allowed between grab_nic_access and
+ * release_nic_access.
+ * @release_nic_access: let the NIC go to sleep. The "flags" parameter
+ * must be the same one that was sent before to the grab_nic_access.
+ * @set_bits_mask - set SRAM register according to value and mask.
+ * @ref: grab a reference to the transport/FW layers, disallowing
+ * certain low power states
+ * @unref: release a reference previously taken with @ref. Note that
+ * initially the reference count is 1, making an initial @unref
+ * necessary to allow low power states.
+ * @dump_data: return a vmalloc'ed buffer with debug data, maybe containing last
+ * TX'ed commands and similar. The buffer will be vfree'd by the caller.
+ * Note that the transport must fill in the proper file headers.

+/**
+ * DOC: station table - introduction
+ *
+ * The station table is a list of data structure that reprensent the stations.
+ * In STA/P2P client mode, the driver will hold one station for the AP/ GO.
+ * In GO/AP mode, the driver will have as many stations as associated clients.
+ * All these stations are reflected in the fw's station table. The driver
+ * keeps the fw's station table up to date with the ADD_STA command. Stations
+ * can be removed by the REMOVE_STA command.
+ *
+ * All the data related to a station is held in the structure %iwl_mvm_sta
+ * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area.
+ * This data includes the index of the station in the fw, per tid information
+ * (sequence numbers, Block-ack state machine, etc...). The stations are
+ * created and deleted by the %sta_state callback from %ieee80211_ops.
+ *
+ * The driver holds a map: %fw_id_to_mac_id that allows to fetch a
+ * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw
+ * station index. That way, the driver is able to get the tid related data in
+ * O(1) in time sensitive paths (Tx / Tx response / BA notification). These
+ * paths are triggered by the fw, and the driver needs to get a pointer to the
+ * %ieee80211 structure. This map helps to get that pointer quickly.
+ */
+
+/**
+ * DOC: station table - locking
+ *
+ * As stated before, the station is created / deleted by mac80211's %sta_state
+ * callback from %ieee80211_ops which can sleep. The next paragraph explains
+ * the locking of a single stations, the next ones relates to the station
+ * table.
+ *
+ * The station holds the sequence number per tid. So this data needs to be
+ * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack
+ * information (the state machine / and the logic that checks if the queues
+ * were drained), so it also needs to be accessible from the Tx response flow.
+ * In short, the station needs to be access from sleepable context as well as
+ * from tasklets, so the station itself needs a spinlock.
+ *
+ * The writers of %fw_id_to_mac_id map are serialized by the global mutex of
+ * the mvm op_mode. This is possible since %sta_state can sleep.
+ * The pointers in this map are RCU protected, hence we won't replace the
+ * station while we have Tx / Tx response / BA notification running.
+ *
+ * If a station is deleted while it still has packets in its A-MPDU queues,
+ * then the reclaim flow will notice that there is no station in the map for
+ * sta_id and it will dump the responses.

+ * The FW needs a few internal stations that are not reflected in
+ * mac80211, such as broadcast station in AP / GO mode, or AUX sta for
+ * scanning and P2P device (during the GO negotiation).
+ * For these kind of stations we have %iwl_mvm_int_sta struct which holds the
+ * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta.
+ * Usually the data for these stations is static, so no locking is required,
+ * and no TID data as this is also not needed.
+ * One thing to note, is that these stations have an ID in the fw, but not
+ * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id
+ * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of
+ * pointers from this mapping need to check that the value is not error
+ * or NULL.
+ *
+ * Currently there is only one auxiliary station for scanning, initialized
+ * on init.
+ */
+
+/**
+ * DOC: station table - AP Station in STA mode
+ *
+ * %iwl_mvm_vif includes the index of the AP station in the fw's STA table:
+ * %ap_sta_id. To get the point to the corresponding %ieee80211_sta,
+ * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove
+ * the AP station from the fw before setting the MAC context as unassociated.
+ * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is
+ * removed by mac80211, but the station won't be removed in the fw until the
+ * VIF is set as unassociated. Then, %ap_sta_id will be invalidated.
+ */
+
+/**
+ * DOC: station table - Drain vs. Flush
+ *
+ * Flush means that all the frames in the SCD queue are dumped regardless the
+ * station to which they were sent. We do that when we disassociate and before
+ * we remove the STA of the AP. The flush can be done synchronously against the
+ * fw.
+ * Drain means that the fw will drop all the frames sent to a specific station.
+ * This is useful when a client (if we are IBSS / GO or AP) disassociates. In
+ * that case, we need to drain all the frames for that client from the AC queues
+ * that are shared with the other clients. Only then, we can remove the STA in
+ * the fw. In order to do so, we track the non-AMPDU packets for each station.
+ * If mac80211 removes a STA and if it still has non-AMPDU packets pending in
+ * the queues, we mark this station as %EBUSY in %fw_id_to_mac_id, and drop all
+ * the frames for this STA (%iwl_mvm_rm_sta). When the last frame is dropped
+ * (we know about it with its Tx response), we remove the station in fw and set
+ * it as %NULL in %fw_id_to_mac_id: this is the purpose of
+ * %iwl_mvm_sta_drained_wk.
+ */
+
+/**
+ * DOC: station table - fw restart
+ *
+ * When the fw asserts, or we have any other issue that requires to reset the
+ * driver, we require mac80211 to reconfigure the driver. Since the private
+ * data of the stations is embed in mac80211's %ieee80211_sta, that data will
+ * not be zeroed and needs to be reinitialized manually.
+ * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us
+ * that we must not allocate a new sta_id but reuse the previous one. This
+ * means that the stations being re-added after the reset will have the same
+ * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id
+ * map, since the stations aren't in the fw any more. Internal stations that
+ * are not added by mac80211 will be re-added in the init flow that is called
+ * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to
+ * %iwl_mvm_up.
+ */
+
+/**
+ * DOC: AP mode - PS
+ *
+ * When a station is asleep, the fw will set it as "asleep". All frames on
+ * shared queues (i.e. non-aggregation queues) to that station will be dropped
+ * by the fw (%TX_STATUS_FAIL_DEST_PS failure code).
+ *
+ * AMPDUs are in a separate queue that is stopped by the fw. We just need to
+ * let mac80211 know when there are frames in these queues so that it can
+ * properly handle trigger frames.
+ *
+ * When a trigger frame is received, mac80211 tells the driver to send frames
+ * from the AMPDU queues or sends frames to non-aggregation queues itself,
+ * depending on which ACs are delivery-enabled and what TID has frames to
+ * transmit. Note that mac80211 has all the knowledge since all the non-agg
+ * frames are buffered / filtered, and the driver tells mac80211 about agg
+ * frames). The driver needs to tell the fw to let frames out even if the
+ * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count.
+ *
+ * When we receive a frame from that station with PM bit unset, the driver
+ * needs to let the fw know that this station isn't asleep any more. This is
+ * done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the
+ * station's wakeup.
+ *
+ * For a GO, the Service Period might be cut short due to an absence period
+ * of the GO. In this (and all other cases) the firmware notifies us with the
+ * EOSP_NOTIFICATION, and we notify mac80211 of that. Further frames that we
+ * already sent to the device will be rejected again.
+ *
+ * See also "AP support for powersaving clients" in mac80211.h.

+/**
+ * DOC: Time Events - what is it?
+ *
+ * Time Events are a fw feature that allows the driver to control the presence
+ * of the device on the channel. Since the fw supports multiple channels
+ * concurrently, the fw may choose to jump to another channel at any time.
+ * In order to make sure that the fw is on a specific channel at a certain time
+ * and for a certain duration, the driver needs to issue a time event.
+ *
+ * The simplest example is for BSS association. The driver issues a time event,
+ * waits for it to start, and only then tells mac80211 that we can start the
+ * association. This way, we make sure that the association will be done
+ * smoothly and won't be interrupted by channel switch decided within the fw.
+ */
+
+ /**
+ * DOC: The flow against the fw
+ *
+ * When the driver needs to make sure we are in a certain channel, at a certain
+ * time and for a certain duration, it sends a Time Event. The flow against the
+ * fw goes like this:
+ * 1) Driver sends a TIME_EVENT_CMD to the fw
+ * 2) Driver gets the response for that command. This response contains the
+ * Unique ID (UID) of the event.
+ * 3) The fw sends notification when the event starts.
+ *
+ * Of course the API provides various options that allow to cover parameters
+ * of the flow.
+ * What is the duration of the event?
+ * What is the start time of the event?
+ * Is there an end-time for the event?
+ * How much can the event be delayed?
+ * Can the event be split?

+ * 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 RBDs is stored in iwl->rxq->rx_free.
+ * When the interrupt handler is called, the request is processed.
+ * The page is either stolen - transferred to the upper layer
+ * or reused - added immediately to the iwl->rxq->rx_free list.
+ * + When the page is stolen - the driver updates the matching queue's used
+ * count, detaches the RBD and transfers it to the queue used list.
+ * When there are two used RBDs - they are transferred to the allocator empty
+ * list. Work is then scheduled for the allocator to start allocating
+ * eight buffers.
+ * When there are another 6 used RBDs - they are transferred to the allocator
+ * empty list and the driver tries to claim the pre-allocated buffers and
+ * add them to iwl->rxq->rx_free. If it fails - it continues to claim them
+ * until ready.
+ * When there are 8+ buffers in the free list - either from allocation or from
+ * 8 reused unstolen pages - restock is called to update the FW and indexes.
+ * + In order to make sure the allocator always has RBDs to use for allocation
+ * the allocator has initial pool in the size of num_queues*(8-2) - the
+ * maximum missing RBDs per allocation request (request posted with 2
+ * empty RBDs, there is no guarantee when the other 6 RBDs are supplied).
+ * The queues supplies the recycle of the rest of the RBDs.
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the iwl->rxq. The driver 'processed' index is updated.
+ * + 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_rxq_alloc() Allocates rx_free
+ * iwl_pcie_rx_replenish() Replenishes rx_free list from rx_used, and calls
+ * iwl_pcie_rxq_restock.
+ * Used only during initialization.
+ * iwl_pcie_rxq_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE index.
+ * iwl_pcie_rx_allocator() Background work for allocating pages.
+ *
+ * -- 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.
+ * Posts and claims requests to the allocator.
+ * Calls iwl_pcie_rxq_restock to refill any empty
+ * slots.
+ *
+ * RBD life-cycle:
+ *
+ * Init:
+ * rxq.pool -> rxq.rx_used -> rxq.rx_free -> rxq.queue
+ *
+ * Regular Receive interrupt:
+ * Page Stolen:
+ * rxq.queue -> rxq.rx_used -> allocator.rbd_empty ->
+ * allocator.rbd_allocated -> rxq.rx_free -> rxq.queue
+ * Page not Stolen:
+ * rxq.queue -> rxq.rx_free -> rxq.queue

+/*************** DMA-QUEUE-GENERAL-FUNCTIONS *****
+ * DMA services
+ *
+ * Theory of operation
+ *
+ * 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.

- Intel Wireless WiFi Link 6250AGN Adapter
- Intel 6000 Series Wi-Fi Adapters (6200AGN and 6300AGN)
- Intel WiFi Link 1000BGN

- Intel 3165 Wi-Fi Adapter
-
-
- This driver uses the kernel's mac80211 subsystem.
-
- In order to use this driver, you will need a firmware
- image for it. You can obtain the microcode from:
-
- <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.
-
- The firmware is typically installed in /lib/firmware. You can
- look in the hotplug script /etc/hotplug/firmware.agent to
- determine which directory FIRMWARE_DIR is set to when the script
- runs.
-
- If you want to compile the driver as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/kbuild/modules.txt>. The
- module will be called iwlwifi.

-config IWLWIFI_BCAST_FILTERING
- bool "Enable broadcast filtering"
- depends on IWLMVM
- help
- Say Y here to enable default bcast filtering configuration.
-
- Enabling broadcast filtering will drop any incoming wireless
- broadcast frames, except some very specific predefined
- patterns (e.g. incoming arp requests).
-
- If unsure, don't enable this option, as some programs might
- expect incoming broadcasts for their normal operations.
-
-config IWLWIFI_UAPSD
- bool "enable U-APSD by default"
- depends on IWLMVM
- help
- Say Y here to enable U-APSD by default. This may cause
- interoperability problems with some APs, manifesting in lower than
- expected throughput due to those APs not enabling aggregation
-
- If unsure, say N.
-
-menu "Debugging Options"
-
-config IWLWIFI_DEBUG
- bool "Enable full debugging output in the iwlwifi driver"
- ---help---
- This option will enable debug tracing output for the iwlwifi drivers
-
- This will result in the kernel module being ~100k larger. You can
- control which debug output is sent to the kernel log by setting the
- value in
-
- /sys/module/iwlwifi/parameters/debug
-
- This entry will only exist if this option is enabled.
-
- To set a value, simply echo an 8-byte hex value to the same file:
-
- % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
-
- You can find the list of debug mask values in:
- drivers/net/wireless/iwlwifi/iwl-debug.h
-
- If this is your first time using this driver, you should say Y here
- as the debug information can assist others in helping you resolve
- any problems you may encounter.
-
-config IWLWIFI_DEBUGFS
- bool "iwlwifi debugfs support"
- depends on MAC80211_DEBUGFS
- ---help---
- Enable creation of debugfs files for the iwlwifi drivers. This
- is a low-impact option that allows getting insight into the
- driver's state at runtime.
-
-config IWLWIFI_DEBUG_EXPERIMENTAL_UCODE
- bool "Experimental uCode support"
- depends on IWLWIFI_DEBUG
- ---help---
- Enable use of experimental ucode for testing and debugging.
-
-config IWLWIFI_DEVICE_TRACING
- bool "iwlwifi device access tracing"
- depends on EVENT_TRACING
- default y
- help
- Say Y here to trace all commands, including TX frames and IO
- accesses, sent to the device. If you say yes, iwlwifi will
- register with the ftrace framework for event tracing and dump
- all this information to the ringbuffer, you may need to
- increase the ringbuffer size. See the ftrace documentation
- for more information.
-
- When tracing is not enabled, this option still has some
- (though rather small) overhead.
-
- If unsure, say Y so we can help you better when problems
- occur.

- * __le32 wraps; # times uCode has wrapped to top of circular buffer

- *
- * __le32 event_id; range 0 - 1500
- * __le32 timestamp; low 32 bits of TSF (of network, if associated)
- * __le32 data; event_id-specific data value
- *
- * Entries without timestamps contain only event_id and data.

- *
- * 2) error_event_table_ptr indicates base of the error log. This contains
- * information about any uCode error that occurs. For agn, the format

- *
- * The rate scaling procedures described below work well. Of course, other
- * procedures are possible, and may work better for particular environments.
- *
- *
- * 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 agn 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 agn 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:
- *
- * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60
- *
- * G: 7 13 35 58 40 57 72 98 121 154 177 186 186
- * A: 0 0 0 0 40 57 72 98 121 154 177 186 186
- * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202
- * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211
- * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251
- * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257
- * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257
- * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264
- * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289
- * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293
- *
- * After the new mode has been tried for a short while (minimum of 6 failed
- * frames or 8 successful frames), compare success ratio and actual throughput
- * estimate of the new mode with the old. If either is better with the new
- * mode, continue to use the new mode.
- *
- * Continue comparing modes until all 3 possibilities have been tried.
- * If moving from legacy to HT, try all 3 possibilities from the new HT
- * mode. After trying all 3, a best mode is found. Continue to use this mode
- * for the longer "while" described above (e.g. 480 successful frames for
- * legacy), and then repeat the search process.

- * 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,
- * down to min 125.
- *
- * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
- * down to min 200.
- *
- * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
- *
- * If actual rate of CCK false alarms (+ plcp_errors) is within good range
- * (between 5 and 50 for each 204.8 msecs listening):
- *
- * 1) Save a snapshot of the silence reference.
- *
- * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
- * give some extra margin to energy threshold by *subtracting* 8
- * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
- *
- * For all cases (too few, too many, good range), make sure that the CCK
- * detection threshold (energy) is below the energy level for robust
- * detection over the past 10 beacon periods, the "Max cck energy".
- * Lower values mean higher energy; this means making sure that the value
- * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

- * This command sets the relative gains of agn device's 3 radio receiver chains.

- *
- * DISCONNECTED ANTENNA:

- * Driver should determine which antennas are actually connected, by comparing

- * 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

- * (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

- *
- * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)

- * Find the weakest background noise level from among a/b/c. This Rx chain

- *
- * (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

- * 3: CT_KILL_EXIT
- * Host sets this to request exit from CT_KILL state, i.e. host thinks
- * device temperature is low enough to continue normal operation.
- * 2: CMD_BLOCKED
- * Host sets this during RF KILL power-down sequence (HW, SW, CT KILL)
- * to release uCode to clear all Tx and command queues, enter
- * unassociated mode, and power down.
- * NOTE: Some devices also use HBUS_TARG_MBX_C register for this bit.
- * 1: SW_BIT_RFKILL
- * Host sets this when issuing CARD_STATE command to request
- * device sleep.
- * 0: MAC_SLEEP
- * uCode sets this when preparing a power-saving power-down.
- * uCode resets this when power-up is complete and SRAM is sane.
- * NOTE: device saves internal SRAM data to host when powering down,
- * and must restore this data after powering back up.
- * MAC_SLEEP is the best indication that restore is complete.
- * Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and

-/**
- * DOC: Driver system flows - drv component
- *
- * This component implements the system flows such as bus enumeration, bus
- * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in
- * bus specific files (transport files). This is the code that is common among
- * different buses.
- *
- * This component is also in charge of managing the several implementations of
- * the wifi flows: it will allow to have several fw API implementation. These
- * different implementations will differ in the way they implement mac80211's
- * handlers too.
-
- * The init flow wrt to the drv component looks like this:
- * 1) The bus specific component is called from module_init
- * 2) The bus specific component registers the bus driver
- * 3) The bus driver calls the probe function
- * 4) The bus specific component configures the bus
- * 5) The bus specific component calls to the drv bus agnostic part
- * (iwl_drv_start)
- * 6) iwl_drv_start fetches the fw ASYNC, iwl_req_fw_callback
- * 7) iwl_req_fw_callback parses the fw file
- * 8) iwl_req_fw_callback starts the wifi implementation to matches the fw

-/**
- * Rx SRAM Control and Status Registers (RSCSR)
- *
- * These registers provide handshake between driver and device for the Rx queue
- * (this queue handles *all* command responses, notifications, Rx data, etc.
- * sent from uCode to host driver). Unlike Tx, there is only one Rx
- * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can
- * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
- * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
- * mapping between RBDs and RBs.
- *
- * Driver must allocate host DRAM memory for the following, and set the
- * physical address of each into device registers:
- *
- * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
- * entries (although any power of 2, up to 4096, is selectable by driver).
- * Each entry (1 dword) points to a receive buffer (RB) of consistent size
- * (typically 4K, although 8K or 16K are also selectable by driver).
- * Driver sets up RB size and number of RBDs in the CB via Rx config
- * register FH_MEM_RCSR_CHNL0_CONFIG_REG.
- *
- * Bit fields within one RBD:
- * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned
- *
- * Driver sets physical address [35:8] of base of RBD circular buffer
- * into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
- *
- * 2) Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
- * (RBs) have been filled, via a "write pointer", actually the index of
- * the RB's corresponding RBD within the circular buffer. Driver sets
- * physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
- *
- * Bit fields in lower dword of Rx status buffer (upper dword not used
- * by driver:
- * 31-12: Not used by driver
- * 11- 0: Index of last filled Rx buffer descriptor
- * (device writes, driver reads this value)
- *
- * As the driver prepares Receive Buffers (RBs) for device to fill, driver must
- * enter pointers to these RBs into contiguous RBD circular buffer entries,
- * and update the device'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: DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
- *
- * As the device 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 device
- *
- * 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, device 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.

- * DOC: Operational mode - what is it ?
- *
- * The operational mode (a.k.a. op_mode) is the layer that implements

- * the transport API to access the HW. The op_mode doesn't need to know how the
- * underlying HW works, since the transport layer takes care of that.
- *
- * There can be several op_mode: i.e. different fw APIs will require two
- * different op_modes. This is why the op_mode is virtualized.
- */
-
-/**
- * DOC: Life cycle of the Operational mode
- *
- * The operational mode has a very simple life cycle.
- *
- * 1) The driver layer (iwl-drv.c) chooses the op_mode based on the
- * capabilities advertised by the fw file (in TLV format).
- * 2) The driver layer starts the op_mode (ops->start)
- * 3) The op_mode registers mac80211
- * 4) The op_mode is governed by mac80211
- * 5) The driver layer stops the op_mode
- */
-
-/**
- * struct iwl_op_mode_ops - op_mode specific operations
- *
- * The op_mode exports its ops so that external components can start it and
- * interact with it. The driver layer typically calls the start and stop
- * handlers, the transport layer calls the others.
- *
- * All the handlers MUST be implemented, except @rx_rss which can be left
- * out *iff* the opmode will never run on hardware with multi-queue capability.
- *
- * @start: start the op_mode. The transport layer is already allocated.
- * May sleep
- * @stop: stop the op_mode. Must free all the memory allocated.
- * May sleep
- * @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
- * HCMD this Rx responds to. Can't sleep.
- * @rx_rss: data queue RX notification to the op_mode, for (data) notifications
- * received on the RSS queue(s). The queue parameter indicates which of the
- * RSS queues received this frame; it will always be non-zero.
- * This method must not sleep.
- * @queue_full: notifies that a HW queue is full.
- * Must be atomic and called with BH disabled.
- * @queue_not_full: notifies that a HW queue is not full any more.
- * Must be atomic and called with BH disabled.
- * @hw_rf_kill:notifies of a change in the HW rf kill switch. True means that
- * the radio is killed. Return %true if the device should be stopped by
- * the transport immediately after the call. May sleep.
- * @free_skb: allows the transport layer to free skbs that haven't been
- * reclaimed by the op_mode. This can happen when the driver is freed and
- * there are Tx packets pending in the transport layer.
- * Must be atomic
- * @nic_error: error notification. Must be atomic and must be called with BH
- * disabled.
- * @cmd_queue_full: Called when the command queue gets full. Must be atomic and
- * called with BH disabled.
- * @nic_config: configure NIC, called before firmware is started.
- * May sleep
- * @wimax_active: invoked when WiMax becomes active. May sleep
- * @enter_d0i3: configure the fw to enter d0i3. return 1 to indicate d0i3
- * entrance is aborted (e.g. due to held reference). May sleep.
- * @exit_d0i3: configure the fw to exit d0i3. May sleep.

-/**
- * 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 5000 series and up, they are used differently
- * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.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 -- unused
- * 5 -- unused
- * 6 -- unused
- * 7 -- Commands
- *
- * 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
- * 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 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

-/**
- * DOC: Transport layer - what is it ?
- *
- * The transport layer is the layer that deals with the HW directly. It provides
- * an abstraction of the underlying HW to the upper layer. The transport layer
- * doesn't provide any policy, algorithm or anything of this kind, but only
- * mechanisms to make the HW do something. It is not completely stateless but
- * close to it.
- * We will have an implementation for each different supported bus.
- */
-
-/**
- * DOC: Life cycle of the transport layer
- *
- * The transport layer has a very precise life cycle.
- *
- * 1) A helper function is called during the module initialization and
- * registers the bus driver's ops with the transport's alloc function.
- * 2) Bus's probe calls to the transport layer's allocation functions.
- * Of course this function is bus specific.
- * 3) This allocation functions will spawn the upper layer which will
- * register mac80211.
- *
- * 4) At some point (i.e. mac80211's start call), the op_mode will call
- * the following sequence:
- * start_hw
- * start_fw
- *
- * 5) Then when finished (or reset):
- * stop_device
- *
- * 6) Eventually, the free function will be called.

- * The transport does provide helper functionality (i.e. SYNC / ASYNC mode),

- * May sleep

- * May sleep

- * the SCD base address in SRAM, then provide it here, or 0 otherwise.
- * May sleep
- * @stop_device: stops the whole device (embedded CPU put to reset) and stops
- * the HW. If low_power is true, the NIC will be put in low power state.
- * From that point on, the HW will be stopped but will still issue an
- * interrupt if the HW RF kill switch is triggered.
- * This callback must do the right thing and not crash even if %start_hw()
- * was called but not &start_fw(). May sleep.
- * @d3_suspend: put the device into the correct mode for WoWLAN during
- * suspend. This is optional, if not implemented WoWLAN will not be
- * supported. This callback may sleep.
- * @d3_resume: resume the device after WoWLAN, enabling the opmode to
- * talk to the WoWLAN image to get its status. This is optional, if not
- * implemented WoWLAN will not be supported. This callback may sleep.
- * @send_cmd:send a host command. Must return -ERFKILL if RFkill is asserted.
- * If RFkill is asserted in the middle of a SYNC host command, it must
- * return -ERFKILL straight away.
- * May sleep only if CMD_ASYNC is not set
- * @tx: send an skb
- * Must be atomic
- * @reclaim: free packet until ssn. Returns a list of freed packets.
- * Must be atomic
- * @txq_enable: setup a queue. To setup an AC queue, use the
- * iwl_trans_ac_txq_enable wrapper. fw_alive must have been called before
- * this one. The op_mode must not configure the HCMD queue. The scheduler
- * configuration may be %NULL, in which case the hardware will not be
- * configured. May sleep.
- * @txq_disable: de-configure a Tx queue to send AMPDUs
- * Must be atomic
- * @wait_tx_queue_empty: wait until tx queues are empty. May sleep.
- * @freeze_txq_timer: prevents the timer of the queue from firing until the
- * queue is set to awake. Must be atomic.
- * @dbgfs_register: add the dbgfs files under this directory. Files will be
- * automatically deleted.
- * @write8: write a u8 to a register at offset ofs from the BAR
- * @write32: write a u32 to a register at offset ofs from the BAR
- * @read32: read a u32 register at offset ofs from the BAR
- * @read_prph: read a DWORD from a periphery register
- * @write_prph: write a DWORD to a periphery register
- * @read_mem: read device's SRAM in DWORD
- * @write_mem: write device's SRAM in DWORD. If %buf is %NULL, then the memory
- * will be zeroed.
- * @configure: configure parameters required by the transport layer from
- * the op_mode. May be called several times before start_fw, can't be
- * called after that.
- * @set_pmi: set the power pmi state
- * @grab_nic_access: wake the NIC to be able to access non-HBUS regs.
- * Sleeping is not allowed between grab_nic_access and
- * release_nic_access.
- * @release_nic_access: let the NIC go to sleep. The "flags" parameter
- * must be the same one that was sent before to the grab_nic_access.
- * @set_bits_mask - set SRAM register according to value and mask.
- * @ref: grab a reference to the transport/FW layers, disallowing
- * certain low power states
- * @unref: release a reference previously taken with @ref. Note that
- * initially the reference count is 1, making an initial @unref
- * necessary to allow low power states.
- * @dump_data: return a vmalloc'ed buffer with debug data, maybe containing last
- * TX'ed commands and similar. The buffer will be vfree'd by the caller.
- * Note that the transport must fill in the proper file headers.

-/**
- * DOC: station table - introduction
- *
- * The station table is a list of data structure that reprensent the stations.
- * In STA/P2P client mode, the driver will hold one station for the AP/ GO.
- * In GO/AP mode, the driver will have as many stations as associated clients.
- * All these stations are reflected in the fw's station table. The driver
- * keeps the fw's station table up to date with the ADD_STA command. Stations
- * can be removed by the REMOVE_STA command.
- *
- * All the data related to a station is held in the structure %iwl_mvm_sta
- * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area.
- * This data includes the index of the station in the fw, per tid information
- * (sequence numbers, Block-ack state machine, etc...). The stations are
- * created and deleted by the %sta_state callback from %ieee80211_ops.
- *
- * The driver holds a map: %fw_id_to_mac_id that allows to fetch a
- * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw
- * station index. That way, the driver is able to get the tid related data in
- * O(1) in time sensitive paths (Tx / Tx response / BA notification). These
- * paths are triggered by the fw, and the driver needs to get a pointer to the
- * %ieee80211 structure. This map helps to get that pointer quickly.

-/**
- * DOC: station table - locking
- *
- * As stated before, the station is created / deleted by mac80211's %sta_state
- * callback from %ieee80211_ops which can sleep. The next paragraph explains
- * the locking of a single stations, the next ones relates to the station
- * table.
- *
- * The station holds the sequence number per tid. So this data needs to be
- * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack
- * information (the state machine / and the logic that checks if the queues
- * were drained), so it also needs to be accessible from the Tx response flow.
- * In short, the station needs to be access from sleepable context as well as
- * from tasklets, so the station itself needs a spinlock.
- *
- * The writers of %fw_id_to_mac_id map are serialized by the global mutex of
- * the mvm op_mode. This is possible since %sta_state can sleep.
- * The pointers in this map are RCU protected, hence we won't replace the
- * station while we have Tx / Tx response / BA notification running.
- *
- * If a station is deleted while it still has packets in its A-MPDU queues,
- * then the reclaim flow will notice that there is no station in the map for
- * sta_id and it will dump the responses.

-/**
- * DOC: station table - internal stations
- *
- * The FW needs a few internal stations that are not reflected in
- * mac80211, such as broadcast station in AP / GO mode, or AUX sta for
- * scanning and P2P device (during the GO negotiation).
- * For these kind of stations we have %iwl_mvm_int_sta struct which holds the
- * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta.
- * Usually the data for these stations is static, so no locking is required,
- * and no TID data as this is also not needed.
- * One thing to note, is that these stations have an ID in the fw, but not
- * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id
- * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of
- * pointers from this mapping need to check that the value is not error
- * or NULL.
- *
- * Currently there is only one auxiliary station for scanning, initialized
- * on init.
- */
-
-/**
- * DOC: station table - AP Station in STA mode
- *
- * %iwl_mvm_vif includes the index of the AP station in the fw's STA table:
- * %ap_sta_id. To get the point to the corresponding %ieee80211_sta,
- * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove
- * the AP station from the fw before setting the MAC context as unassociated.
- * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is
- * removed by mac80211, but the station won't be removed in the fw until the
- * VIF is set as unassociated. Then, %ap_sta_id will be invalidated.

-
-/**
- * DOC: station table - Drain vs. Flush
- *
- * Flush means that all the frames in the SCD queue are dumped regardless the
- * station to which they were sent. We do that when we disassociate and before
- * we remove the STA of the AP. The flush can be done synchronously against the
- * fw.
- * Drain means that the fw will drop all the frames sent to a specific station.
- * This is useful when a client (if we are IBSS / GO or AP) disassociates. In
- * that case, we need to drain all the frames for that client from the AC queues
- * that are shared with the other clients. Only then, we can remove the STA in
- * the fw. In order to do so, we track the non-AMPDU packets for each station.
- * If mac80211 removes a STA and if it still has non-AMPDU packets pending in
- * the queues, we mark this station as %EBUSY in %fw_id_to_mac_id, and drop all
- * the frames for this STA (%iwl_mvm_rm_sta). When the last frame is dropped
- * (we know about it with its Tx response), we remove the station in fw and set
- * it as %NULL in %fw_id_to_mac_id: this is the purpose of
- * %iwl_mvm_sta_drained_wk.
- */
-
-/**
- * DOC: station table - fw restart
- *
- * When the fw asserts, or we have any other issue that requires to reset the
- * driver, we require mac80211 to reconfigure the driver. Since the private
- * data of the stations is embed in mac80211's %ieee80211_sta, that data will
- * not be zeroed and needs to be reinitialized manually.
- * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us
- * that we must not allocate a new sta_id but reuse the previous one. This
- * means that the stations being re-added after the reset will have the same
- * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id
- * map, since the stations aren't in the fw any more. Internal stations that
- * are not added by mac80211 will be re-added in the init flow that is called
- * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to
- * %iwl_mvm_up.
- */
-
-/**
- * DOC: AP mode - PS
- *
- * When a station is asleep, the fw will set it as "asleep". All frames on
- * shared queues (i.e. non-aggregation queues) to that station will be dropped
- * by the fw (%TX_STATUS_FAIL_DEST_PS failure code).
- *
- * AMPDUs are in a separate queue that is stopped by the fw. We just need to
- * let mac80211 know when there are frames in these queues so that it can
- * properly handle trigger frames.
- *
- * When a trigger frame is received, mac80211 tells the driver to send frames
- * from the AMPDU queues or sends frames to non-aggregation queues itself,
- * depending on which ACs are delivery-enabled and what TID has frames to
- * transmit. Note that mac80211 has all the knowledge since all the non-agg
- * frames are buffered / filtered, and the driver tells mac80211 about agg
- * frames). The driver needs to tell the fw to let frames out even if the
- * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count.
- *
- * When we receive a frame from that station with PM bit unset, the driver
- * needs to let the fw know that this station isn't asleep any more. This is
- * done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the
- * station's wakeup.
- *
- * For a GO, the Service Period might be cut short due to an absence period
- * of the GO. In this (and all other cases) the firmware notifies us with the
- * EOSP_NOTIFICATION, and we notify mac80211 of that. Further frames that we
- * already sent to the device will be rejected again.
- *
- * See also "AP support for powersaving clients" in mac80211.h.

-/**
- * DOC: Time Events - what is it?
- *
- * Time Events are a fw feature that allows the driver to control the presence
- * of the device on the channel. Since the fw supports multiple channels
- * concurrently, the fw may choose to jump to another channel at any time.
- * In order to make sure that the fw is on a specific channel at a certain time
- * and for a certain duration, the driver needs to issue a time event.
- *
- * The simplest example is for BSS association. The driver issues a time event,
- * waits for it to start, and only then tells mac80211 that we can start the
- * association. This way, we make sure that the association will be done
- * smoothly and won't be interrupted by channel switch decided within the fw.
- */
-
- /**
- * DOC: The flow against the fw
- *
- * When the driver needs to make sure we are in a certain channel, at a certain
- * time and for a certain duration, it sends a Time Event. The flow against the
- * fw goes like this:
- * 1) Driver sends a TIME_EVENT_CMD to the fw
- * 2) Driver gets the response for that command. This response contains the
- * Unique ID (UID) of the event.
- * 3) The fw sends notification when the event starts.
- *
- * Of course the API provides various options that allow to cover parameters
- * of the flow.
- * What is the duration of the event?
- * What is the start time of the event?
- * Is there an end-time for the event?
- * How much can the event be delayed?
- * Can the event be split?
- * If yes what is the maximal number of chunks?

- * 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 RBDs is stored in iwl->rxq->rx_free.
- * When the interrupt handler is called, the request is processed.
- * The page is either stolen - transferred to the upper layer
- * or reused - added immediately to the iwl->rxq->rx_free list.
- * + When the page is stolen - the driver updates the matching queue's used
- * count, detaches the RBD and transfers it to the queue used list.
- * When there are two used RBDs - they are transferred to the allocator empty
- * list. Work is then scheduled for the allocator to start allocating
- * eight buffers.
- * When there are another 6 used RBDs - they are transferred to the allocator
- * empty list and the driver tries to claim the pre-allocated buffers and
- * add them to iwl->rxq->rx_free. If it fails - it continues to claim them
- * until ready.
- * When there are 8+ buffers in the free list - either from allocation or from
- * 8 reused unstolen pages - restock is called to update the FW and indexes.
- * + In order to make sure the allocator always has RBDs to use for allocation
- * the allocator has initial pool in the size of num_queues*(8-2) - the
- * maximum missing RBDs per allocation request (request posted with 2
- * empty RBDs, there is no guarantee when the other 6 RBDs are supplied).
- * The queues supplies the recycle of the rest of the RBDs.
- * + A received packet is processed and handed to the kernel network stack,
- * detached from the iwl->rxq. The driver 'processed' index is updated.
- * + 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_rxq_alloc() Allocates rx_free
- * iwl_pcie_rx_replenish() Replenishes rx_free list from rx_used, and calls
- * iwl_pcie_rxq_restock.
- * Used only during initialization.
- * iwl_pcie_rxq_restock() Moves available buffers from rx_free into Rx
- * queue, updates firmware pointers, and updates
- * the WRITE index.
- * iwl_pcie_rx_allocator() Background work for allocating pages.
- *
- * -- 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.
- * Posts and claims requests to the allocator.
- * Calls iwl_pcie_rxq_restock to refill any empty
- * slots.
- *
- * RBD life-cycle:
- *
- * Init:
- * rxq.pool -> rxq.rx_used -> rxq.rx_free -> rxq.queue
- *
- * Regular Receive interrupt:
- * Page Stolen:
- * rxq.queue -> rxq.rx_used -> allocator.rbd_empty ->
- * allocator.rbd_allocated -> rxq.rx_free -> rxq.queue
- * Page not Stolen:
- * rxq.queue -> rxq.rx_free -> rxq.queue
- * ...

-/*************** DMA-QUEUE-GENERAL-FUNCTIONS *****
- * DMA services
- *
- * Theory of operation
- *
- * 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.
