407 * See comments documenting "BSM" (bootstrap state machine).
409 * This response includes two pointers to structures within the device's
410 * data SRAM (access via HBUS_TARG_MEM_* regs) that are useful for debugging:
412 * 1) log_event_table_ptr indicates base of the event log. This traces
413 * a 256-entry history of uCode execution within a circular buffer.
414 * Its header format is:
416 * __le32 log_size; log capacity (in number of entries)
417 * __le32 type; (1) timestamp with each entry, (0) no timestamp
418 * __le32 wraps; # times uCode has wrapped to top of circular buffer
419 * __le32 write_index; next circular buffer entry that uCode would fill
421 * The header is followed by the circular buffer of log entries. Entries
422 * with timestamps have the following format:
424 * __le32 event_id; range 0 - 1500
425 * __le32 timestamp; low 32 bits of TSF (of network, if associated)
426 * __le32 data; event_id-specific data value
428 * Entries without timestamps contain only event_id and data.
431 * 2) error_event_table_ptr indicates base of the error log. This contains
432 * information about any uCode error that occurs. For agn, the format
433 * of the error log is defined by struct iwl_error_event_table.
435 * The Linux driver can print both logs to the system log when a uCode error
440 * Note: This structure is read from the device with IO accesses,
441 * and the reading already does the endian conversion. As it is
442 * read with u32-sized accesses, any members with a different size
443 * need to be ordered correctly though!

1663 * FILLING THE RATE TABLE
1665 * Given a particular initial rate and mode, as determined by the rate
1666 * scaling algorithm described below, the Linux driver uses the following
1667 * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
1668 * Link Quality command:
1671 * 1) If using High-throughput (HT) (SISO or MIMO) initial rate:
1672 * a) Use this same initial rate for first 3 entries.
1673 * b) Find next lower available rate using same mode (SISO or MIMO),
1674 * use for next 3 entries. If no lower rate available, switch to
1675 * legacy mode (no HT40 channel, no MIMO, no short guard interval).
1676 * c) If using MIMO, set command's mimo_delimiter to number of entries
1677 * using MIMO (3 or 6).
1678 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
1679 * no MIMO, no short guard interval), at the next lower bit rate
1680 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow
1681 * legacy procedure for remaining table entries.
1683 * 2) If using legacy initial rate:
1684 * a) Use the initial rate for only one entry.
1685 * b) For each following entry, reduce the rate to next lower available
1686 * rate, until reaching the lowest available rate.
1687 * c) When reducing rate, also switch antenna selection.
1688 * d) Once lowest available rate is reached, repeat this rate until
1689 * rate table is filled (16 entries), switching antenna each entry.
1692 * ACCUMULATING HISTORY
1694 * The rate scaling algorithm for agn devices, as implemented in Linux driver,
1695 * uses two sets of frame Tx success history: One for the current/active
1696 * modulation mode, and one for a speculative/search mode that is being
1697 * attempted. If the speculative mode turns out to be more effective (i.e.
1698 * actual transfer rate is better), then the driver continues to use the
1699 * speculative mode as the new current active mode.
1701 * Each history set contains, separately for each possible rate, data for a
1702 * sliding window of the 62 most recent tx attempts at that rate. The data
1703 * includes a shifting bitmap of success(1)/failure(0), and sums of successful
1704 * and attempted frames, from which the driver can additionally calculate a
1705 * success ratio (success / attempted) and number of failures
1706 * (attempted - success), and control the size of the window (attempted).
1707 * The driver uses the bit map to remove successes from the success sum, as
1708 * the oldest tx attempts fall out of the window.
1710 * When the agn device makes multiple tx attempts for a given frame, each
1711 * attempt might be at a different rate, and have different modulation
1712 * characteristics (e.g. antenna, fat channel, short guard interval), as set
1713 * up in the rate scaling table in the Link Quality command. The driver must
1714 * determine which rate table entry was used for each tx attempt, to determine
1715 * which rate-specific history to update, and record only those attempts that
1716 * match the modulation characteristics of the history set.
1718 * When using block-ack (aggregation), all frames are transmitted at the same
1719 * rate, since there is no per-attempt acknowledgment from the destination
1720 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in
1721 * rate_n_flags field. After receiving a block-ack, the driver can update
1722 * history for the entire block all at once.
1725 * FINDING BEST STARTING RATE:
1727 * When working with a selected initial modulation mode (see below), the
1728 * driver attempts to find a best initial rate. The initial rate is the
1729 * first entry in the Link Quality command's rate table.
1731 * 1) Calculate actual throughput (success ratio * expected throughput, see
1732 * table below) for current initial rate. Do this only if enough frames
1733 * have been attempted to make the value meaningful: at least 6 failed
1734 * tx attempts, or at least 8 successes. If not enough, don't try rate
1737 * 2) Find available rates adjacent to current initial rate. Available means:
1738 * a) supported by hardware &&
1739 * b) supported by association &&
1740 * c) within any constraints selected by user
1742 * 3) Gather measured throughputs for adjacent rates. These might not have
1743 * enough history to calculate a throughput. That's okay, we might try
1744 * using one of them anyway!
1746 * 4) Try decreasing rate if, for current rate:
1747 * a) success ratio is < 15% ||
1748 * b) lower adjacent rate has better measured throughput ||
1749 * c) higher adjacent rate has worse throughput, and lower is unmeasured
1751 * As a sanity check, if decrease was determined above, leave rate
1753 * a) lower rate unavailable
1754 * b) success ratio at current rate > 85% (very good)
1755 * c) current measured throughput is better than expected throughput
1756 * of lower rate (under perfect 100% tx conditions, see table below)
1758 * 5) Try increasing rate if, for current rate:
1759 * a) success ratio is < 15% ||
1760 * b) both adjacent rates' throughputs are unmeasured (try it!) ||
1761 * b) higher adjacent rate has better measured throughput ||
1762 * c) lower adjacent rate has worse throughput, and higher is unmeasured
1764 * As a sanity check, if increase was determined above, leave rate
1766 * a) success ratio at current rate < 70%. This is not particularly
1767 * good performance; higher rate is sure to have poorer success.
1769 * 6) Re-evaluate the rate after each tx frame. If working with block-
1770 * acknowledge, history and statistics may be calculated for the entire
1771 * block (including prior history that fits within the history windows),
1772 * before re-evaluation.
1774 * FINDING BEST STARTING MODULATION MODE:
1776 * After working with a modulation mode for a "while" (and doing rate scaling),
1777 * the driver searches for a new initial mode in an attempt to improve
1778 * throughput. The "while" is measured by numbers of attempted frames:
1780 * For legacy mode, search for new mode after:
1781 * 480 successful frames, or 160 failed frames
1782 * For high-throughput modes (SISO or MIMO), search for new mode after:
1783 * 4500 successful frames, or 400 failed frames
1785 * Mode switch possibilities are (3 for each mode):
1788 * Change antenna, try SISO (if HT association), try MIMO (if HT association)
1790 * Change antenna, try MIMO, try shortened guard interval (SGI)
1792 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
1794 * When trying a new mode, use the same bit rate as the old/current mode when
1795 * trying antenna switches and shortened guard interval. When switching to
1796 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
1797 * for which the expected throughput (under perfect conditions) is about the
1798 * same or slightly better than the actual measured throughput delivered by
1799 * the old/current mode.
1801 * Actual throughput can be estimated by multiplying the expected throughput
1802 * by the success ratio (successful / attempted tx frames). Frame size is
1803 * not considered in this calculation; it assumes that frame size will average
1804 * out to be fairly consistent over several samples. The following are
1805 * metric values for expected throughput assuming 100% success ratio.
1806 * Only G band has support for CCK rates:
1808 * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60
1810 * G: 7 13 35 58 40 57 72 98 121 154 177 186 186
1811 * A: 0 0 0 0 40 57 72 98 121 154 177 186 186
1812 * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202
1813 * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211
1814 * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251
1815 * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257
1816 * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257
1817 * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264
1818 * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289
1819 * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293
1821 * After the new mode has been tried for a short while (minimum of 6 failed
1822 * frames or 8 successful frames), compare success ratio and actual throughput
1823 * estimate of the new mode with the old. If either is better with the new
1824 * mode, continue to use the new mode.
1826 * Continue comparing modes until all 3 possibilities have been tried.
1827 * If moving from legacy to HT, try all 3 possibilities from the new HT
1828 * mode. After trying all 3, a best mode is found. Continue to use this mode
1829 * for the longer "while" described above (e.g. 480 successful frames for
1830 * legacy), and then repeat the search process.

2323 * REPLY_SCAN_CMD = 0x80 (command)
2325 * The hardware scan command is very powerful; the driver can set it up to
2326 * maintain (relatively) normal network traffic while doing a scan in the
2327 * background. The max_out_time and suspend_time control the ratio of how
2328 * long the device stays on an associated network channel ("service channel")
2329 * vs. how long it's away from the service channel, i.e. tuned to other channels
2332 * max_out_time is the max time off-channel (in usec), and suspend_time
2333 * is how long (in "extended beacon" format) that the scan is "suspended"
2334 * after returning to the service channel. That is, suspend_time is the
2335 * time that we stay on the service channel, doing normal work, between
2336 * scan segments. The driver may set these parameters differently to support
2337 * scanning when associated vs. not associated, and light vs. heavy traffic
2338 * loads when associated.
2340 * After receiving this command, the device's scan engine does the following;
2342 * 1) Sends SCAN_START notification to driver
2343 * 2) Checks to see if it has time to do scan for one channel
2344 * 3) Sends NULL packet, with power-save (PS) bit set to 1,
2345 * to tell AP that we're going off-channel
2346 * 4) Tunes to first channel in scan list, does active or passive scan
2347 * 5) Sends SCAN_RESULT notification to driver
2348 * 6) Checks to see if it has time to do scan on *next* channel in list
2349 * 7) Repeats 4-6 until it no longer has time to scan the next channel
2350 * before max_out_time expires
2351 * 8) Returns to service channel
2352 * 9) Sends NULL packet with PS=0 to tell AP that we're back
2353 * 10) Stays on service channel until suspend_time expires
2354 * 11) Repeats entire process 2-10 until list is complete
2355 * 12) Sends SCAN_COMPLETE notification
2357 * For fast, efficient scans, the scan command also has support for staying on
2358 * a channel for just a short time, if doing active scanning and getting no
2359 * responses to the transmitted probe request. This time is controlled by
2360 * quiet_time, and the number of received packets below which a channel is
2361 * considered "quiet" is controlled by quiet_plcp_threshold.
2363 * For active scanning on channels that have regulatory restrictions against
2364 * blindly transmitting, the scan can listen before transmitting, to make sure
2365 * that there is already legitimate activity on the channel. If enough
2366 * packets are cleanly received on the channel (controlled by good_CRC_th,
2367 * typical value 1), the scan engine starts transmitting probe requests.
2369 * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
2371 * To avoid uCode errors, see timing restrictions described under
2372 * struct iwl_scan_channel.

2877 * Measure of energy of desired signal. Used for establishing a level
2878 * below which the device does not detect signals.
2880 * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
2881 * Measure of background noise in silent period after beacon.
2884 * uSecs of actual Rx time during beacon period (varies according to
2885 * how much time was spent transmitting).
2887 * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
2890 * Signal locks abandoned early (before phy-level header).
2893 * Signal locks abandoned late (during phy-level header).
2895 * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
2896 * beacon to beacon, i.e. each value is an accumulation of all errors
2897 * before and including the latest beacon. Values will wrap around to 0
2898 * after counting up to 2^32 - 1. Driver must differentiate vs.
2899 * previous beacon's values to determine # false alarms in the current
2902 * Total number of false alarms = false_alarms + plcp_errs
2904 * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
2905 * (notice that the start points for OFDM are at or close to settings for
2906 * maximum sensitivity):
2909 * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
2910 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
2911 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
2912 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
2914 * If actual rate of OFDM false alarms (+ plcp_errors) is too high
2915 * (greater than 50 for each 204.8 msecs listening), reduce sensitivity
2916 * by *adding* 1 to all 4 of the table entries above, up to the max for
2917 * each entry. Conversely, if false alarm rate is too low (less than 5
2918 * for each 204.8 msecs listening), *subtract* 1 from each entry to
2919 * increase sensitivity.
2921 * For CCK sensitivity, keep track of the following:
2923 * 1). 20-beacon history of maximum background noise, indicated by
2924 * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
2925 * 3 receivers. For any given beacon, the "silence reference" is
2926 * the maximum of last 60 samples (20 beacons * 3 receivers).
2928 * 2). 10-beacon history of strongest signal level, as indicated
2929 * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
2930 * i.e. the strength of the signal through the best receiver at the
2931 * moment. These measurements are "upside down", with lower values
2932 * for stronger signals, so max energy will be *minimum* value.
2934 * Then for any given beacon, the driver must determine the *weakest*
2935 * of the strongest signals; this is the minimum level that needs to be
2936 * successfully detected, when using the best receiver at the moment.
2937 * "Max cck energy" is the maximum (higher value means lower energy!)
2938 * of the last 10 minima. Once this is determined, driver must add
2939 * a little margin by adding "6" to it.
2941 * 3). Number of consecutive beacon periods with too few false alarms.
2942 * Reset this to 0 at the first beacon period that falls within the
2943 * "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
2945 * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
2946 * (notice that the start points for CCK are at maximum sensitivity):
2949 * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
2950 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
2951 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
2953 * If actual rate of CCK false alarms (+ plcp_errors) is too high
2954 * (greater than 50 for each 204.8 msecs listening), method for reducing
2957 * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2960 * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
2961 * sensitivity has been reduced a significant amount; bring it up to
2962 * a moderate 161. Otherwise, *add* 3, up to max 200.
2964 * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
2965 * sensitivity has been reduced only a moderate or small amount;
2966 * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
2967 * down to min 0. Otherwise (if gain has been significantly reduced),
2968 * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
2970 * b) Save a snapshot of the "silence reference".
2972 * If actual rate of CCK false alarms (+ plcp_errors) is too low
2973 * (less than 5 for each 204.8 msecs listening), method for increasing
2974 * sensitivity is used only if:
2976 * 1a) Previous beacon did not have too many false alarms
2977 * 1b) AND difference between previous "silence reference" and current
2978 * "silence reference" (prev - current) is 2 or more,
2979 * OR 2) 100 or more consecutive beacon periods have had rate of
2980 * less than 5 false alarms per 204.8 milliseconds rx time.
2982 * Method for increasing sensitivity:
2984 * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
2987 * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2990 * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
2992 * If actual rate of CCK false alarms (+ plcp_errors) is within good range
2993 * (between 5 and 50 for each 204.8 msecs listening):
2995 * 1) Save a snapshot of the silence reference.
2997 * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
2998 * give some extra margin to energy threshold by *subtracting* 8
2999 * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
3001 * For all cases (too few, too many, good range), make sure that the CCK
3002 * detection threshold (energy) is below the energy level for robust
3003 * detection over the past 10 beacon periods, the "Max cck energy".
3004 * Lower values mean higher energy; this means making sure that the value
3005 * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

3103 * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20

3107 * DISCONNECTED ANTENNA:
3109 * Driver should determine which antennas are actually connected, by comparing
3110 * average beacon signal levels for the 3 Rx chains. Accumulate (add) the
3111 * following values over 20 beacons, one accumulator for each of the chains
3112 * a/b/c, from struct statistics_rx_non_phy:
3114 * beacon_rssi_[abc] & 0x0FF (unsigned, units in dB)
3116 * Find the strongest signal from among a/b/c. Compare the other two to the
3117 * strongest. If any signal is more than 15 dB (times 20, unless you
3118 * divide the accumulated values by 20) below the strongest, the driver
3119 * considers that antenna to be disconnected, and should not try to use that
3120 * antenna/chain for Rx or Tx. If both A and B seem to be disconnected,
3121 * driver should declare the stronger one as connected, and attempt to use it
3122 * (A and B are the only 2 Tx chains!).
3127 * Driver should balance the 3 receivers (but just the ones that are connected
3128 * to antennas, see above) for gain, by comparing the average signal levels
3129 * detected during the silence after each beacon (background noise).
3130 * Accumulate (add) the following values over 20 beacons, one accumulator for
3131 * each of the chains a/b/c, from struct statistics_rx_non_phy:
3133 * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
3135 * Find the weakest background noise level from among a/b/c. This Rx chain
3136 * will be the reference, with 0 gain adjustment. Attenuate other channels by
3137 * finding noise difference:
3139 * (accum_noise[i] - accum_noise[reference]) / 30
3141 * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
3142 * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
3143 * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
3144 * and set bit 2 to indicate "reduce gain". The value for the reference
3145 * (weakest) chain should be "0".
