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

- * __le32 wraps; # times uCode has wrapped to top of circular buffer
- * __le32 write_index; next circular buffer entry that uCode would fill

- * The header is followed by the circular buffer of log entries. Entries
- * with timestamps have the following format:
- *
- * __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
- * of the error log is defined by struct iwl_error_event_table.

- *
- *
- * 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.

- *
- *****************************************************************************/

-/**
- * 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.
- *

- * 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
- * (weakest) chain should be "0".
- *
- * diff_gain_[abc] bit fields:
- * 2: (1) reduce gain, (0) increase gain
- * 1-0: amount of gain, units of 1.5 dB
