- bool "iwlwifilegacy legacy device access tracing"
- depends on IWLWIFI_LEGACY
- depends on EVENT_TRACING
- help
- Say Y here to trace all commands, including TX frames and IO
- accesses, sent to the device. If you say yes, iwlwifilegacy 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.

Subject: [PATCH 02/77] iwlegacy: rename iwl to il

iwl_legacy prefix result in long function names, what cause that we
have frequent line split and not readable code. Also iwl_foo symbols
are duplicated in iwlwifi driver, what is annoying when editing
kernel tree with cscope.

For the same reason as in other patches - for make code shorter.

Actually rx_reply is confusing name for interrupt handler.

:-) it's shortcut from "handler", but you known it, don't you ?

I think this particular change would make the code less readable. It's
one thing to replace TABLE with TBL, but S_ can be anything - signed,
special, settable, stable...

You may want to replace RF_KILL with RFKILL if you are desperate to
shorten variable names.

+ * scaling algorithm described below, the Linux driver uses the following
+ * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
+ * Link Quality command:
+ *
+ *
+ * 1) If using High-throughput (HT) (SISO or MIMO) initial rate:
+ * a) Use this same initial rate for first 3 entries.
+ * b) Find next lower available rate using same mode (SISO or MIMO),
+ * use for next 3 entries. If no lower rate available, switch to
+ * legacy mode (no HT40 channel, no MIMO, no short guard interval).
+ * c) If using MIMO, set command's mimo_delimiter to number of entries
+ * using MIMO (3 or 6).
+ * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
+ * no MIMO, no short guard interval), at the next lower bit rate
+ * (e.g. if second HT bit rate was 54, try 48 legacy), and follow
+ * legacy procedure for remaining table entries.
+ *
+ * 2) If using legacy initial rate:
+ * a) Use the initial rate for only one entry.
+ * b) For each following entry, reduce the rate to next lower available
+ * rate, until reaching the lowest available rate.
+ * c) When reducing rate, also switch antenna selection.
+ * d) Once lowest available rate is reached, repeat this rate until
+ * rate table is filled (16 entries), switching antenna each entry.
+ *
+ *
+ * ACCUMULATING HISTORY
+ *
+ * The rate scaling algorithm for 4965 devices, as implemented in Linux driver,
+ * uses two sets of frame Tx success history: One for the current/active
+ * modulation mode, and one for a speculative/search mode that is being
+ * attempted. If the speculative mode turns out to be more effective (i.e.
+ * actual transfer rate is better), then the driver continues to use the
+ * speculative mode as the new current active mode.
+ *
+ * Each history set contains, separately for each possible rate, data for a
+ * sliding win 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 win (attempted).
+ * The driver uses the bit map to remove successes from the success sum, as
+ * the oldest tx attempts fall out of the win.
+ *
+ * When the 4965 device makes multiple tx attempts for a given frame, each
+ * attempt might be at a different rate, and have different modulation
+ * characteristics (e.g. antenna, fat channel, short guard interval), as set
+ * up in the rate scaling table in the Link Quality command. The driver must
+ * determine which rate table entry was used for each tx attempt, to determine
+ * which rate-specific history to update, and record only those attempts that
+ * match the modulation characteristics of the history set.
+ *
+ * When using block-ack (aggregation), all frames are transmitted at the same
+ * rate, since there is no per-attempt acknowledgment from the destination
+ * station. The Tx response struct il_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 stats may be calculated for the entire
+ * block (including prior history that fits within the history wins),
+ * 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.

+ * C_SCAN = 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 il_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:
+ *
+ * 1) Tx power (depends on temperature), described elsewhere
+ * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
+ * 3) Receiver sensitivity (to optimize signal detection)
+ *
+ *****************************************************************************/
+
+/**
+ * C_SENSITIVITY = 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 N_STATSs after each
+ * received beacon. These provide information to the driver to analyze the
+ * sensitivity. Don't analyze stats that come in from scanning, or any
+ * other non-associated-network source. Pertinent stats include:
+ *
+ * From "general" stats (struct stats_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" stats (struct stats_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 il_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_IDX 90 / 85 / 120
+ * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_IDX 170 / 170 / 210
+ * HD_AUTO_CORR32_X4_TH_ADD_MIN_IDX 105 / 105 / 140
+ * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_IDX 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 il_sensitivity_cmd
+ * (notice that the start points for CCK are at maximum sensitivity):
+ *

+ * C_PHY_CALIBRATION = 0xb0 (command, has simple generic response)
+ *
+ * This command sets the relative gains of 4965 device's 3 radio receiver chains.
+ *
+ * After the first association, driver should accumulate signal and noise
+ * stats from the N_STATSs that follow the first 20
+ * beacons from the associated network (don't collect stats 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 stats_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 stats_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 il_calibration_cmd, the
+ * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
+ * and set bit 2 to indicate "reduce gain". The value for the reference
+ * (weakest) chain should be "0".

- *
- * __le32 log_size; log capacity (in number of entries)

- * __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 4965, the format
- * of the error log is:
- *
- * __le32 valid; (nonzero) valid, (0) log is empty

- *
- *
- * FILLING THE RATE TBL
- *
- * Given a particular initial rate and mode, as determined by the rate
- * scaling algorithm described below, the Linux driver uses the following
- * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
- * Link Quality command:
- *
- *
- * 1) If using High-throughput (HT) (SISO or MIMO) initial rate:
- * a) Use this same initial rate for first 3 entries.
- * b) Find next lower available rate using same mode (SISO or MIMO),
- * use for next 3 entries. If no lower rate available, switch to
- * legacy mode (no HT40 channel, no MIMO, no short guard interval).
- * c) If using MIMO, set command's mimo_delimiter to number of entries
- * using MIMO (3 or 6).
- * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
- * no MIMO, no short guard interval), at the next lower bit rate
- * (e.g. if second HT bit rate was 54, try 48 legacy), and follow
- * legacy procedure for remaining table entries.
- *
- * 2) If using legacy initial rate:
- * a) Use the initial rate for only one entry.
- * b) For each following entry, reduce the rate to next lower available
- * rate, until reaching the lowest available rate.
- * c) When reducing rate, also switch antenna selection.
- * d) Once lowest available rate is reached, repeat this rate until
- * rate table is filled (16 entries), switching antenna each entry.
- *
- *
- * ACCUMULATING HISTORY
- *
- * The rate scaling algorithm for 4965 devices, as implemented in Linux driver,
- * uses two sets of frame Tx success history: One for the current/active
- * modulation mode, and one for a speculative/search mode that is being
- * attempted. If the speculative mode turns out to be more effective (i.e.
- * actual transfer rate is better), then the driver continues to use the
- * speculative mode as the new current active mode.
- *
- * Each history set contains, separately for each possible rate, data for a
- * sliding win 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 win (attempted).
- * The driver uses the bit map to remove successes from the success sum, as
- * the oldest tx attempts fall out of the win.
- *
- * When the 4965 device makes multiple tx attempts for a given frame, each
- * attempt might be at a different rate, and have different modulation
- * characteristics (e.g. antenna, fat channel, short guard interval), as set
- * up in the rate scaling table in the Link Quality command. The driver must
- * determine which rate table entry was used for each tx attempt, to determine
- * which rate-specific history to update, and record only those attempts that
- * match the modulation characteristics of the history set.
- *
- * When using block-ack (aggregation), all frames are transmitted at the same
- * rate, since there is no per-attempt acknowledgment from the destination
- * station. The Tx response struct il_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 stats may be calculated for the entire
- * block (including prior history that fits within the history wins),
- * 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.

-/*
- * C_SCAN = 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 il_scan_channel.

- * (11)
- * Rx Calibration Commands:
- *
- * With the uCode used for open source drivers, most Tx calibration (except
- * for Tx Power) and most Rx calibration is done by uCode during the
- * "initialize" phase of uCode boot. Driver must calibrate only:
- *
- * 1) Tx power (depends on temperature), described elsewhere
- * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
- * 3) Receiver sensitivity (to optimize signal detection)
- *
- *****************************************************************************/
-
-/**
- * C_SENSITIVITY = 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 N_STATSs after each
- * received beacon. These provide information to the driver to analyze the
- * sensitivity. Don't analyze stats that come in from scanning, or any
- * other non-associated-network source. Pertinent stats include:
- *
- * From "general" stats (struct stats_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" stats (struct stats_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 il_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_IDX 90 / 85 / 120
- * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_IDX 170 / 170 / 210
- * HD_AUTO_CORR32_X4_TH_ADD_MIN_IDX 105 / 105 / 140
- * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_IDX 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 il_sensitivity_cmd
- * (notice that the start points for CCK are at maximum sensitivity):
- *
- * START / MIN / MAX
- * HD_AUTO_CORR40_X4_TH_ADD_MIN_IDX 125 / 125 / 200
- * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_IDX 200 / 200 / 400
- * HD_MIN_ENERGY_CCK_DET_IDX 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_IDX,
- * up to max 400.
- *
- * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_IDX 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_IDX is > 160,
- * sensitivity has been reduced only a moderate or small amount;
- * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_IDX,
- * down to min 0. Otherwise (if gain has been significantly reduced),
- * don't change the HD_MIN_ENERGY_CCK_DET_IDX 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_IDX,
- * down to min 125.
- *
- * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_IDX,
- * down to min 200.
- *
- * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_IDX, 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_IDX.
- *
- * 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_IDX is at or *above* "Max cck energy".

- *
- * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
- *
- * Find the weakest background noise level from among a/b/c. This Rx chain

- *
- * 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 il_calibration_cmd, the

+ *
+ * For example, il_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into il->channel_info_24/52 and il->channel_map_24/52
+ *
+ * channel_map_24/52 provides the idx in the channel_info array for a
+ * given channel. We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware. This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that

+/*
+ * 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 idxes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two idx registers for managing the Rx buffers.
+ *
+ * The READ idx 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 idx is managed by the firmware once the card is enabled.
+ *
+ * The WRITE idx 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
+ * IDX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ idx
+ * and fire the RX interrupt. The driver can then query the READ idx and
+ * process as many packets as possible, moving the WRITE idx forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
+ * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replenish the iwl->rxq->rx_free.
+ * + In il_rx_replenish (scheduled) if 'processed' != 'read' then the
+ * iwl->rxq is replenished and the READ IDX is updated (updating the
+ * 'processed' and 'read' driver idxes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the iwl->rxq. The driver 'processed' idx is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ * IDX 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:
+ *
+ * il_rx_queue_alloc() Allocates rx_free
+ * il_rx_replenish() Replenishes rx_free list from rx_used, and calls
+ * il_rx_queue_restock
+ * il_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE idx. If insufficient rx_free buffers
+ * are available, schedules il_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - il_rx() Detach il_rx_bufs from pool up to the
+ * READ IDX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls il_rx_queue_restock to refill any empty

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

-/************************** RX-FUNCTIONS ****************************/
-/*
- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC. These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC. The driver and NIC manage the Rx buffers by means
- * of idxes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two idx registers for managing the Rx buffers.
- *
- * The READ idx 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 idx is managed by the firmware once the card is enabled.
- *
- * The WRITE idx 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
- * IDX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ idx
- * and fire the RX interrupt. The driver can then query the READ idx and
- * process as many packets as possible, moving the WRITE idx forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
- * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- * to replenish the iwl->rxq->rx_free.
- * + In il_rx_replenish (scheduled) if 'processed' != 'read' then the
- * iwl->rxq is replenished and the READ IDX is updated (updating the
- * 'processed' and 'read' driver idxes as well)
- * + A received packet is processed and handed to the kernel network stack,
- * detached from the iwl->rxq. The driver 'processed' idx is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- * IDX 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:
- *
- * il_rx_queue_alloc() Allocates rx_free
- * il_rx_replenish() Replenishes rx_free list from rx_used, and calls
- * il_rx_queue_restock
- * il_rx_queue_restock() Moves available buffers from rx_free into Rx
- * queue, updates firmware pointers, and updates
- * the WRITE idx. If insufficient rx_free buffers
- * are available, schedules il_rx_replenish
- *
- * -- enable interrupts --
- * ISR - il_rx() Detach il_rx_bufs from pool up to the
- * READ IDX, detaching the SKB from the pool.
- * Moves the packet buffer from queue to rx_used.
- * Calls il_rx_queue_restock to refill any empty
- * slots.
- * ...

- * 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.

+
+/**
+ * To calculate a txpower setting for a given desired target txpower, channel,
+ * modulation bit rate, and transmitter chain (4965 has 2 transmitters to
+ * support MIMO and transmit diversity), driver must do the following:
+ *
+ * 1) Compare desired txpower vs. (EEPROM) regulatory limit for this channel.
+ * Do not exceed regulatory limit; reduce target txpower if necessary.
+ *
+ * If setting up txpowers for MIMO rates (rate idxes 8-15, 24-31),
+ * 2 transmitters will be used simultaneously; driver must reduce the
+ * regulatory limit by 3 dB (half-power) for each transmitter, so the
+ * combined total output of the 2 transmitters is within regulatory limits.
+ *
+ *
+ * 2) Compare target txpower vs. (EEPROM) saturation txpower *reduced by
+ * backoff for this bit rate*. Do not exceed (saturation - backoff[rate]);
+ * reduce target txpower if necessary.
+ *
+ * Backoff values below are in 1/2 dB units (equivalent to steps in
+ * txpower gain tables):
+ *
+ * OFDM 6 - 36 MBit: 10 steps (5 dB)
+ * OFDM 48 MBit: 15 steps (7.5 dB)
+ * OFDM 54 MBit: 17 steps (8.5 dB)
+ * OFDM 60 MBit: 20 steps (10 dB)
+ * CCK all rates: 10 steps (5 dB)
+ *
+ * Backoff values apply to saturation txpower on a per-transmitter basis;
+ * when using MIMO (2 transmitters), each transmitter uses the same
+ * saturation level provided in EEPROM, and the same backoff values;
+ * no reduction (such as with regulatory txpower limits) is required.
+ *
+ * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel
+ * widths and 40 Mhz (.11n HT40) channel widths; there is no separate
+ * factory measurement for ht40 channels.
+ *
+ * The result of this step is the final target txpower. The rest of
+ * the steps figure out the proper settings for the device to achieve
+ * that target txpower.
+ *
+ *
+ * 3) Determine (EEPROM) calibration sub band for the target channel, by
+ * comparing against first and last channels in each sub band
+ * (see struct il4965_eeprom_calib_subband_info).
+ *
+ *
+ * 4) Linearly interpolate (EEPROM) factory calibration measurement sets,
+ * referencing the 2 factory-measured (sample) channels within the sub band.
+ *
+ * Interpolation is based on difference between target channel's frequency
+ * and the sample channels' frequencies. Since channel numbers are based
+ * on frequency (5 MHz between each channel number), this is equivalent
+ * to interpolating based on channel number differences.
+ *
+ * Note that the sample channels may or may not be the channels at the
+ * edges of the sub band. The target channel may be "outside" of the
+ * span of the sampled channels.
+ *
+ * Driver may choose the pair (for 2 Tx chains) of measurements (see
+ * struct il4965_eeprom_calib_ch_info) for which the actual measured
+ * txpower comes closest to the desired txpower. Usually, though,
+ * the middle set of measurements is closest to the regulatory limits,
+ * and is therefore a good choice for all txpower calculations (this
+ * assumes that high accuracy is needed for maximizing legal txpower,
+ * while lower txpower configurations do not need as much accuracy).
+ *
+ * Driver should interpolate both members of the chosen measurement pair,
+ * i.e. for both Tx chains (radio transmitters), unless the driver knows
+ * that only one of the chains will be used (e.g. only one tx antenna
+ * connected, but this should be unusual). The rate scaling algorithm
+ * switches antennas to find best performance, so both Tx chains will
+ * be used (although only one at a time) even for non-MIMO transmissions.
+ *
+ * Driver should interpolate factory values for temperature, gain table
+ * idx, and actual power. The power amplifier detector values are
+ * not used by the driver.
+ *
+ * Sanity check: If the target channel happens to be one of the sample
+ * channels, the results should agree with the sample channel's
+ * measurements!
+ *
+ *
+ * 5) Find difference between desired txpower and (interpolated)
+ * factory-measured txpower. Using (interpolated) factory gain table idx
+ * (shown elsewhere) as a starting point, adjust this idx lower to
+ * increase txpower, or higher to decrease txpower, until the target
+ * txpower is reached. Each step in the gain table is 1/2 dB.
+ *
+ * For example, if factory measured txpower is 16 dBm, and target txpower
+ * is 13 dBm, add 6 steps to the factory gain idx to reduce txpower
+ * by 3 dB.
+ *
+ *
+ * 6) Find difference between current device temperature and (interpolated)
+ * factory-measured temperature for sub-band. Factory values are in
+ * degrees Celsius. To calculate current temperature, see comments for
+ * "4965 temperature calculation".
+ *
+ * If current temperature is higher than factory temperature, driver must
+ * increase gain (lower gain table idx), and vice verse.
+ *
+ * Temperature affects gain differently for different channels:
+ *
+ * 2.4 GHz all channels: 3.5 degrees per half-dB step
+ * 5 GHz channels 34-43: 4.5 degrees per half-dB step
+ * 5 GHz channels >= 44: 4.0 degrees per half-dB step
+ *
+ * NOTE: Temperature can increase rapidly when transmitting, especially
+ * with heavy traffic at high txpowers. Driver should update
+ * temperature calculations often under these conditions to
+ * maintain strong txpower in the face of rising temperature.
+ *
+ *
+ * 7) Find difference between current power supply voltage indicator
+ * (from "initialize alive") and factory-measured power supply voltage
+ * indicator (EEPROM).
+ *
+ * If the current voltage is higher (indicator is lower) than factory
+ * voltage, gain should be reduced (gain table idx increased) by:
+ *
+ * (eeprom - current) / 7
+ *
+ * If the current voltage is lower (indicator is higher) than factory
+ * voltage, gain should be increased (gain table idx decreased) by:
+ *
+ * 2 * (current - eeprom) / 7
+ *
+ * If number of idx steps in either direction turns out to be > 2,
+ * something is wrong ... just use 0.
+ *
+ * NOTE: Voltage compensation is independent of band/channel.
+ *
+ * NOTE: "Initialize" uCode measures current voltage, which is assumed
+ * to be constant after this initial measurement. Voltage
+ * compensation for txpower (number of steps in gain table)
+ * may be calculated once and used until the next uCode bootload.
+ *
+ *
+ * 8) If setting up txpowers for MIMO rates (rate idxes 8-15, 24-31),
+ * adjust txpower for each transmitter chain, so txpower is balanced
+ * between the two chains. There are 5 pairs of tx_atten[group][chain]
+ * values in "initialize alive", one pair for each of 5 channel ranges:
+ *
+ * Group 0: 5 GHz channel 34-43
+ * Group 1: 5 GHz channel 44-70
+ * Group 2: 5 GHz channel 71-124
+ * Group 3: 5 GHz channel 125-200
+ * Group 4: 2.4 GHz all channels
+ *
+ * Add the tx_atten[group][chain] value to the idx for the target chain.
+ * The values are signed, but are in pairs of 0 and a non-negative number,
+ * so as to reduce gain (if necessary) of the "hotter" channel. This
+ * avoids any need to double-check for regulatory compliance after
+ * this step.
+ *
+ *
+ * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation
+ * value to the idx:
+ *
+ * Hardware rev B: 9 steps (4.5 dB)
+ * Hardware rev C: 5 steps (2.5 dB)
+ *
+ * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG,
+ * bits [3:2], 1 = B, 2 = C.
+ *
+ * NOTE: This compensation is in addition to any saturation backoff that
+ * might have been applied in an earlier step.
+ *
+ *
+ * 10) Select the gain table, based on band (2.4 vs 5 GHz).
+ *
+ * Limit the adjusted idx to stay within the table!
+ *
+ *
+ * 11) Read gain table entries for DSP and radio gain, place into appropriate
+ * location(s) in command (struct il4965_txpowertable_cmd).

+ *
+ * 4965 supports up to 16 DRAM-based Tx queues, and services these queues via

-/**
- * To calculate a txpower setting for a given desired target txpower, channel,
- * modulation bit rate, and transmitter chain (4965 has 2 transmitters to
- * support MIMO and transmit diversity), driver must do the following:
- *
- * 1) Compare desired txpower vs. (EEPROM) regulatory limit for this channel.
- * Do not exceed regulatory limit; reduce target txpower if necessary.
- *
- * If setting up txpowers for MIMO rates (rate idxes 8-15, 24-31),
- * 2 transmitters will be used simultaneously; driver must reduce the
- * regulatory limit by 3 dB (half-power) for each transmitter, so the
- * combined total output of the 2 transmitters is within regulatory limits.
- *
- *
- * 2) Compare target txpower vs. (EEPROM) saturation txpower *reduced by
- * backoff for this bit rate*. Do not exceed (saturation - backoff[rate]);
- * reduce target txpower if necessary.
- *
- * Backoff values below are in 1/2 dB units (equivalent to steps in
- * txpower gain tables):
- *
- * OFDM 6 - 36 MBit: 10 steps (5 dB)
- * OFDM 48 MBit: 15 steps (7.5 dB)
- * OFDM 54 MBit: 17 steps (8.5 dB)
- * OFDM 60 MBit: 20 steps (10 dB)
- * CCK all rates: 10 steps (5 dB)
- *
- * Backoff values apply to saturation txpower on a per-transmitter basis;
- * when using MIMO (2 transmitters), each transmitter uses the same
- * saturation level provided in EEPROM, and the same backoff values;
- * no reduction (such as with regulatory txpower limits) is required.
- *
- * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel
- * widths and 40 Mhz (.11n HT40) channel widths; there is no separate
- * factory measurement for ht40 channels.
- *
- * The result of this step is the final target txpower. The rest of
- * the steps figure out the proper settings for the device to achieve
- * that target txpower.
- *
- *
- * 3) Determine (EEPROM) calibration sub band for the target channel, by
- * comparing against first and last channels in each sub band
- * (see struct il4965_eeprom_calib_subband_info).
- *
- *
- * 4) Linearly interpolate (EEPROM) factory calibration measurement sets,
- * referencing the 2 factory-measured (sample) channels within the sub band.
- *
- * Interpolation is based on difference between target channel's frequency
- * and the sample channels' frequencies. Since channel numbers are based
- * on frequency (5 MHz between each channel number), this is equivalent
- * to interpolating based on channel number differences.
- *
- * Note that the sample channels may or may not be the channels at the
- * edges of the sub band. The target channel may be "outside" of the
- * span of the sampled channels.
- *
- * Driver may choose the pair (for 2 Tx chains) of measurements (see
- * struct il4965_eeprom_calib_ch_info) for which the actual measured
- * txpower comes closest to the desired txpower. Usually, though,
- * the middle set of measurements is closest to the regulatory limits,
- * and is therefore a good choice for all txpower calculations (this
- * assumes that high accuracy is needed for maximizing legal txpower,
- * while lower txpower configurations do not need as much accuracy).
- *
- * Driver should interpolate both members of the chosen measurement pair,
- * i.e. for both Tx chains (radio transmitters), unless the driver knows
- * that only one of the chains will be used (e.g. only one tx antenna
- * connected, but this should be unusual). The rate scaling algorithm
- * switches antennas to find best performance, so both Tx chains will
- * be used (although only one at a time) even for non-MIMO transmissions.
- *
- * Driver should interpolate factory values for temperature, gain table
- * idx, and actual power. The power amplifier detector values are
- * not used by the driver.
- *
- * Sanity check: If the target channel happens to be one of the sample
- * channels, the results should agree with the sample channel's
- * measurements!
- *
- *
- * 5) Find difference between desired txpower and (interpolated)
- * factory-measured txpower. Using (interpolated) factory gain table idx
- * (shown elsewhere) as a starting point, adjust this idx lower to
- * increase txpower, or higher to decrease txpower, until the target
- * txpower is reached. Each step in the gain table is 1/2 dB.
- *
- * For example, if factory measured txpower is 16 dBm, and target txpower
- * is 13 dBm, add 6 steps to the factory gain idx to reduce txpower
- * by 3 dB.
- *
- *
- * 6) Find difference between current device temperature and (interpolated)
- * factory-measured temperature for sub-band. Factory values are in
- * degrees Celsius. To calculate current temperature, see comments for
- * "4965 temperature calculation".
- *
- * If current temperature is higher than factory temperature, driver must
- * increase gain (lower gain table idx), and vice verse.
- *
- * Temperature affects gain differently for different channels:
- *
- * 2.4 GHz all channels: 3.5 degrees per half-dB step
- * 5 GHz channels 34-43: 4.5 degrees per half-dB step
- * 5 GHz channels >= 44: 4.0 degrees per half-dB step
- *
- * NOTE: Temperature can increase rapidly when transmitting, especially
- * with heavy traffic at high txpowers. Driver should update
- * temperature calculations often under these conditions to
- * maintain strong txpower in the face of rising temperature.
- *
- *
- * 7) Find difference between current power supply voltage indicator
- * (from "initialize alive") and factory-measured power supply voltage
- * indicator (EEPROM).
- *
- * If the current voltage is higher (indicator is lower) than factory
- * voltage, gain should be reduced (gain table idx increased) by:
- *
- * (eeprom - current) / 7
- *
- * If the current voltage is lower (indicator is higher) than factory
- * voltage, gain should be increased (gain table idx decreased) by:
- *
- * 2 * (current - eeprom) / 7
- *
- * If number of idx steps in either direction turns out to be > 2,
- * something is wrong ... just use 0.
- *
- * NOTE: Voltage compensation is independent of band/channel.
- *
- * NOTE: "Initialize" uCode measures current voltage, which is assumed
- * to be constant after this initial measurement. Voltage
- * compensation for txpower (number of steps in gain table)
- * may be calculated once and used until the next uCode bootload.
- *
- *
- * 8) If setting up txpowers for MIMO rates (rate idxes 8-15, 24-31),
- * adjust txpower for each transmitter chain, so txpower is balanced
- * between the two chains. There are 5 pairs of tx_atten[group][chain]
- * values in "initialize alive", one pair for each of 5 channel ranges:
- *
- * Group 0: 5 GHz channel 34-43
- * Group 1: 5 GHz channel 44-70
- * Group 2: 5 GHz channel 71-124
- * Group 3: 5 GHz channel 125-200
- * Group 4: 2.4 GHz all channels
- *
- * Add the tx_atten[group][chain] value to the idx for the target chain.
- * The values are signed, but are in pairs of 0 and a non-negative number,
- * so as to reduce gain (if necessary) of the "hotter" channel. This
- * avoids any need to double-check for regulatory compliance after
- * this step.
- *
- *
- * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation
- * value to the idx:
- *
- * Hardware rev B: 9 steps (4.5 dB)
- * Hardware rev C: 5 steps (2.5 dB)
- *
- * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG,
- * bits [3:2], 1 = B, 2 = C.
- *
- * NOTE: This compensation is in addition to any saturation backoff that
- * might have been applied in an earlier step.
- *
- *
- * 10) Select the gain table, based on band (2.4 vs 5 GHz).
- *
- * Limit the adjusted idx to stay within the table!
- *
- *
- * 11) Read gain table entries for DSP and radio gain, place into appropriate
- * location(s) in command (struct il4965_txpowertable_cmd).

- *
- * Each entry contains two values:

- * Tx/Rx Queues
- *

- * For example, all commands that the driver issues to device's embedded
- * controller (uCode) are via the command queue (one of the Tx queues). All
- * uCode command responses/replies/notifications, including Rx frames, are
- * conveyed from uCode to driver via the Rx queue.
- *
- * Most support for these queues, including handshake support, resides in
- * structures in host DRAM, shared between the driver and the device. When
- * allocating this memory, the driver must make sure that data written by
- * the host CPU updates DRAM immediately (and does not get "stuck" in CPU's
- * cache memory), so DRAM and cache are consistent, and the device can
- * immediately see changes made by the driver.
- *
- * 4965 supports up to 16 DRAM-based Tx queues, and services these queues via
- * up to 7 DMA channels (FIFOs). Each Tx queue is supported by a circular array
- * in DRAM containing 256 Transmit Frame Descriptors (TFDs).

- * duplicate the first 64 entries (to avoid wrap-around within a Tx win;
- * max Tx win is 64 TFDs).
- *
- * When driver sets up a new TFD, it must also enter the total byte count
- * of the frame to be transmitted into the corresponding entry in the byte
- * count table for the chosen Tx queue. If the TFD idx is 0-63, the driver
- * must duplicate the byte count entry in corresponding idx 256-319.

+ * Rx SRAM Control and Status Registers (RSCSR)
+ *
+ * These registers provide handshake between driver and 4965 for the Rx queue
+ * (this queue handles *all* command responses, notifications, Rx data, etc.
+ * sent from 4965 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 4965 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 FH49_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 FH49_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
+ *
+ * 2) Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers
+ * (RBs) have been filled, via a "write pointer", actually the idx of
+ * the RB's corresponding RBD within the circular buffer. Driver sets
+ * physical address [35:4] into FH49_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
+ *
+ * Bit fields in lower dword of Rx status buffer (upper dword not used
+ * by driver; see struct il4965_shared, val0):
+ * 31-12: Not used by driver
+ * 11- 0: Index of last filled Rx buffer descriptor
+ * (4965 writes, driver reads this value)
+ *
+ * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
+ * enter pointers to these RBs into contiguous RBD circular buffer entries,
+ * and update the 4965's "write" idx register,
+ * FH49_RSCSR_CHNL0_RBDCB_WPTR_REG.
+ *
+ * This "write" idx 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" idx has advanced past 1! See below).
+ * NOTE: 4965 EXPECTS THE WRITE IDX TO BE INCREMENTED IN MULTIPLES OF 8.
+ *
+ * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
+ * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
+ * to tell the driver the idx of the latest filled RBD. The driver must
+ * read this "read" idx from DRAM after receiving an Rx interrupt from 4965.
+ *
+ * The driver must also internally keep track of a third idx, 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" idx. For example, if "read" idx 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 idx == write idx, 4965 thinks there is no room to put new data.
+ * Due to this, the maximum number of filled RBs is 255, instead of 256. To
+ * be safe, make sure that there is a gap of at least 2 RBDs between "write"
+ * and "read" idxes; that is, make sure that there are no more than 254
+ * buffers waiting to be filled.

-/**
- * Rx SRAM Control and Status Registers (RSCSR)
- *
- * These registers provide handshake between driver and 4965 for the Rx queue
- * (this queue handles *all* command responses, notifications, Rx data, etc.
- * sent from 4965 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 4965 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 FH49_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 FH49_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
- *
- * 2) Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers
- * (RBs) have been filled, via a "write pointer", actually the idx of
- * the RB's corresponding RBD within the circular buffer. Driver sets
- * physical address [35:4] into FH49_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
- *
- * Bit fields in lower dword of Rx status buffer (upper dword not used
- * by driver; see struct il4965_shared, val0):
- * 31-12: Not used by driver
- * 11- 0: Index of last filled Rx buffer descriptor
- * (4965 writes, driver reads this value)
- *
- * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must
- * enter pointers to these RBs into contiguous RBD circular buffer entries,
- * and update the 4965's "write" idx register,
- * FH49_RSCSR_CHNL0_RBDCB_WPTR_REG.
- *
- * This "write" idx 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" idx has advanced past 1! See below).
- * NOTE: 4965 EXPECTS THE WRITE IDX TO BE INCREMENTED IN MULTIPLES OF 8.
- *
- * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
- * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
- * to tell the driver the idx of the latest filled RBD. The driver must
- * read this "read" idx from DRAM after receiving an Rx interrupt from 4965.
- *
- * The driver must also internally keep track of a third idx, 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" idx. For example, if "read" idx 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 idx == write idx, 4965 thinks there is no room to put new data.
- * Due to this, the maximum number of filled RBs is 255, instead of 256. To
- * be safe, make sure that there is a gap of at least 2 RBDs between "write"
- * and "read" idxes; that is, make sure that there are no more than 254
- * buffers waiting to be filled.

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

-/**
- * Tx Scheduler
- *
- * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
- * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
- * host DRAM. It steers each frame's Tx command (which contains the frame
- * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
- * device. A queue maps to only one (selectable by driver) Tx DMA channel,
- * but one DMA channel may take input from several queues.
- *
- * Tx DMA FIFOs have dedicated purposes. For 4965, they are used as follows
- * (cf. default_queue_to_tx_fifo in 4965.c):
- *
- * 0 -- EDCA BK (background) frames, lowest priority
- * 1 -- EDCA BE (best effort) frames, normal priority
- * 2 -- EDCA VI (video) frames, higher priority
- * 3 -- EDCA VO (voice) and management frames, highest priority
- * 4 -- Commands (e.g. RXON, etc.)
- * 5 -- unused (HCCA)
- * 6 -- unused (HCCA)
- * 7 -- not used by driver (device-internal only)
- *
- *
- * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
- * In addition, driver can map the remaining queues to Tx DMA/FIFO
- * channels 0-3 to support 11n aggregation via EDCA DMA channels.
- *
- * The driver sets up each queue to work in one of two modes:
- *
- * 1) Scheduler-Ack, in which the scheduler automatically supports a
- * block-ack (BA) win 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 win, including whether it's been transmitted,
- * and whether it's been acknowledged by the receiving station. The device
- * automatically processes block-acks received from the receiving STA,
- * and reschedules un-acked frames to be retransmitted (successful
- * Tx completion may end up being out-of-order).
- *
- * The driver must maintain the queue's Byte Count table in host DRAM
- * (struct il4965_sched_queue_byte_cnt_tbl) for this mode.
- * This mode does not support fragmentation.
- *
- * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
- * The device may automatically retry Tx, but will retry only one frame
- * at a time, until receiving ACK from receiving station, or reaching
- * retry limit and giving up.
- *
- * The command queue (#4/#9) must use this mode!
- * This mode does not require use of the Byte Count table in host DRAM.
- *
- * Driver controls scheduler operation via 3 means:
- * 1) Scheduler registers
- * 2) Shared scheduler data base in internal 4956 SRAM
- * 3) Shared data in host DRAM
- *
- * Initialization:
- *
- * When loading, driver should allocate memory for:
- * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs.
- * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory
- * (1024 bytes for each queue).
- *
- * After receiving "Alive" response from uCode, driver must initialize
- * the scheduler (especially for queue #4/#9, the command queue, otherwise
- * the driver can't issue commands!):
- */
-
-/**
- * Max Tx win size is the max number of contiguous TFDs that the scheduler
- * can keep track of at one time when creating block-ack chains of frames.
- * Note that "64" matches the number of ack bits in a block-ack packet.

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

+/**
+ * Tx Scheduler
+ *
+ * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
+ * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
+ * host DRAM. It steers each frame's Tx command (which contains the frame
+ * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
+ * device. A queue maps to only one (selectable by driver) Tx DMA channel,
+ * but one DMA channel may take input from several queues.
+ *
+ * Tx DMA FIFOs have dedicated purposes. For 4965, they are used as follows
+ * (cf. default_queue_to_tx_fifo in 4965.c):
+ *
+ * 0 -- EDCA BK (background) frames, lowest priority
+ * 1 -- EDCA BE (best effort) frames, normal priority
+ * 2 -- EDCA VI (video) frames, higher priority
+ * 3 -- EDCA VO (voice) and management frames, highest priority
+ * 4 -- Commands (e.g. RXON, etc.)
+ * 5 -- unused (HCCA)
+ * 6 -- unused (HCCA)
+ * 7 -- not used by driver (device-internal only)
+ *
+ *
+ * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
+ * In addition, driver can map the remaining queues to Tx DMA/FIFO
+ * channels 0-3 to support 11n aggregation via EDCA DMA channels.
+ *
+ * The driver sets up each queue to work in one of two modes:
+ *
+ * 1) Scheduler-Ack, in which the scheduler automatically supports a
+ * block-ack (BA) win 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 win, including whether it's been transmitted,
+ * and whether it's been acknowledged by the receiving station. The device
+ * automatically processes block-acks received from the receiving STA,
+ * and reschedules un-acked frames to be retransmitted (successful
+ * Tx completion may end up being out-of-order).
+ *
+ * The driver must maintain the queue's Byte Count table in host DRAM
+ * (struct il4965_sched_queue_byte_cnt_tbl) for this mode.
+ * This mode does not support fragmentation.
+ *
+ * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
+ * The device may automatically retry Tx, but will retry only one frame
+ * at a time, until receiving ACK from receiving station, or reaching
+ * retry limit and giving up.
+ *
+ * The command queue (#4/#9) must use this mode!
+ * This mode does not require use of the Byte Count table in host DRAM.
+ *
+ * Driver controls scheduler operation via 3 means:
+ * 1) Scheduler registers
+ * 2) Shared scheduler data base in internal 4956 SRAM
+ * 3) Shared data in host DRAM
+ *
+ * Initialization:
+ *
+ * When loading, driver should allocate memory for:
+ * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs.
+ * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory
+ * (1024 bytes for each queue).
+ *
+ * After receiving "Alive" response from uCode, driver must initialize
+ * the scheduler (especially for queue #4/#9, the command queue, otherwise
+ * the driver can't issue commands!):
+ */
+
+/**
+ * Max Tx win size is the max number of contiguous TFDs that the scheduler
+ * can keep track of at one time when creating block-ack chains of frames.
+ * Note that "64" matches the number of ack bits in a block-ack packet.

+ * @fw_name_pre: Firmware filename prefix. The api version and extension
+ * (.ucode) will be added to filename before loading from disk. The

+ * @ucode_api_max: Highest version of uCode API supported by driver.
+ * @ucode_api_min: Lowest version of uCode API supported by driver.
+ * @scan_antennas: available antenna for scan operation
+ * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
+ *
+ * We enable the driver to be backward compatible wrt API version. The
+ * driver specifies which APIs it supports (with @ucode_api_max being the
+ * highest and @ucode_api_min the lowest). Firmware will only be loaded if
+ * it has a supported API version. The firmware's API version will be
+ * stored in @il_priv, enabling the driver to make runtime changes based
+ * on firmware version used.
+ *
+ * For example,
+ * if (IL_UCODE_API(il->ucode_ver) >= 2) {
+ * Driver interacts with Firmware API version >= 2.
+ * } else {
+ * Driver interacts with Firmware API version 1.
+ * }
+ *
+ * The ideal usage of this infrastructure is to treat a new ucode API
+ * release as a new hardware revision. That is, through utilizing the
+ * il_hcmd_utils_ops etc. we accommodate different command structures
+ * and flows between hardware versions as well as their API

- * struct il_cfg
- * @fw_name_pre: Firmware filename prefix. The api version and extension
- * (.ucode) will be added to filename before loading from disk. The
- * filename is constructed as fw_name_pre<api>.ucode.
- * @ucode_api_max: Highest version of uCode API supported by driver.
- * @ucode_api_min: Lowest version of uCode API supported by driver.
- * @scan_antennas: available antenna for scan operation
- * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
- *
- * We enable the driver to be backward compatible wrt API version. The
- * driver specifies which APIs it supports (with @ucode_api_max being the
- * highest and @ucode_api_min the lowest). Firmware will only be loaded if
- * it has a supported API version. The firmware's API version will be
- * stored in @il_priv, enabling the driver to make runtime changes based
- * on firmware version used.
- *
- * For example,
- * if (IL_UCODE_API(il->ucode_ver) >= 2) {
- * Driver interacts with Firmware API version >= 2.
- * } else {
- * Driver interacts with Firmware API version 1.
- * }
- *
- * The ideal usage of this infrastructure is to treat a new ucode API
- * release as a new hardware revision. That is, through utilizing the
- * il_hcmd_utils_ops etc. we accommodate different command structures
- * and flows between hardware versions as well as their API
- * versions.
