407  *
408  *     Entries without timestamps contain only event_id and data.
409  *
410  *
411  * 2)  error_event_table_ptr indicates base of the error log.  This contains

1637  * FILLING THE RATE TABLE
1638  *
1639  * Given a particular initial rate and mode, as determined by the rate
1640  * scaling algorithm described below, the Linux driver uses the following
1641  * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
1642  * Link Quality command:
1643  *
1644  *
1645  * 1)  If using High-throughput (HT) (SISO or MIMO) initial rate:
1646  *     a) Use this same initial rate for first 3 entries.
1647  *     b) Find next lower available rate using same mode (SISO or MIMO),
1648  *        use for next 3 entries.  If no lower rate available, switch to
1649  *        legacy mode (no HT40 channel, no MIMO, no short guard interval).
1650  *     c) If using MIMO, set command's mimo_delimiter to number of entries
1651  *        using MIMO (3 or 6).
1652  *     d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
1653  *        no MIMO, no short guard interval), at the next lower bit rate
1654  *        (e.g. if second HT bit rate was 54, try 48 legacy), and follow
1655  *        legacy procedure for remaining table entries.
1656  *
1657  * 2)  If using legacy initial rate:
1658  *     a) Use the initial rate for only one entry.
1659  *     b) For each following entry, reduce the rate to next lower available
1660  *        rate, until reaching the lowest available rate.
1661  *     c) When reducing rate, also switch antenna selection.
1662  *     d) Once lowest available rate is reached, repeat this rate until
1663  *        rate table is filled (16 entries), switching antenna each entry.
1664  *
1665  *
1666  * ACCUMULATING HISTORY
1667  *
1668  * The rate scaling algorithm for agn devices, as implemented in Linux driver,
1669  * uses two sets of frame Tx success history:  One for the current/active
1670  * modulation mode, and one for a speculative/search mode that is being
1671  * attempted. If the speculative mode turns out to be more effective (i.e.
1672  * actual transfer rate is better), then the driver continues to use the
1673  * speculative mode as the new current active mode.
1674  *
1675  * Each history set contains, separately for each possible rate, data for a
1676  * sliding window of the 62 most recent tx attempts at that rate.  The data
1677  * includes a shifting bitmap of success(1)/failure(0), and sums of successful
1678  * and attempted frames, from which the driver can additionally calculate a
1679  * success ratio (success / attempted) and number of failures
1680  * (attempted - success), and control the size of the window (attempted).
1681  * The driver uses the bit map to remove successes from the success sum, as
1682  * the oldest tx attempts fall out of the window.
1683  *
1684  * When the agn device makes multiple tx attempts for a given frame, each
1685  * attempt might be at a different rate, and have different modulation
1686  * characteristics (e.g. antenna, fat channel, short guard interval), as set
1687  * up in the rate scaling table in the Link Quality command.  The driver must
1688  * determine which rate table entry was used for each tx attempt, to determine
1689  * which rate-specific history to update, and record only those attempts that
1690  * match the modulation characteristics of the history set.
1691  *
1692  * When using block-ack (aggregation), all frames are transmitted at the same
1693  * rate, since there is no per-attempt acknowledgment from the destination
1694  * station.  The Tx response struct iwl_tx_resp indicates the Tx rate in
1695  * rate_n_flags field.  After receiving a block-ack, the driver can update
1696  * history for the entire block all at once.
1697  *
1698  *
1699  * FINDING BEST STARTING RATE:
1700  *
1701  * When working with a selected initial modulation mode (see below), the
1702  * driver attempts to find a best initial rate.  The initial rate is the
1703  * first entry in the Link Quality command's rate table.
1704  *
1705  * 1)  Calculate actual throughput (success ratio * expected throughput, see
1706  *     table below) for current initial rate.  Do this only if enough frames
1707  *     have been attempted to make the value meaningful:  at least 6 failed
1708  *     tx attempts, or at least 8 successes.  If not enough, don't try rate
1709  *     scaling yet.
1710  *
1711  * 2)  Find available rates adjacent to current initial rate.  Available means:
1712  *     a)  supported by hardware &&
1713  *     b)  supported by association &&
1714  *     c)  within any constraints selected by user
1715  *
1716  * 3)  Gather measured throughputs for adjacent rates.  These might not have
1717  *     enough history to calculate a throughput.  That's okay, we might try
1718  *     using one of them anyway!
1719  *
1720  * 4)  Try decreasing rate if, for current rate:
1721  *     a)  success ratio is < 15% ||
1722  *     b)  lower adjacent rate has better measured throughput ||
1723  *     c)  higher adjacent rate has worse throughput, and lower is unmeasured
1724  *
1725  *     As a sanity check, if decrease was determined above, leave rate
1726  *     unchanged if:
1727  *     a)  lower rate unavailable
1728  *     b)  success ratio at current rate > 85% (very good)
1729  *     c)  current measured throughput is better than expected throughput
1730  *         of lower rate (under perfect 100% tx conditions, see table below)
1731  *
1732  * 5)  Try increasing rate if, for current rate:
1733  *     a)  success ratio is < 15% ||
1734  *     b)  both adjacent rates' throughputs are unmeasured (try it!) ||
1735  *     b)  higher adjacent rate has better measured throughput ||
1736  *     c)  lower adjacent rate has worse throughput, and higher is unmeasured
1737  *
1738  *     As a sanity check, if increase was determined above, leave rate
1739  *     unchanged if:
1740  *     a)  success ratio at current rate < 70%.  This is not particularly
1741  *         good performance; higher rate is sure to have poorer success.
1742  *
1743  * 6)  Re-evaluate the rate after each tx frame.  If working with block-
1744  *     acknowledge, history and statistics may be calculated for the entire
1745  *     block (including prior history that fits within the history windows),
1746  *     before re-evaluation.
1747  *
1748  * FINDING BEST STARTING MODULATION MODE:
1749  *
1750  * After working with a modulation mode for a "while" (and doing rate scaling),
1751  * the driver searches for a new initial mode in an attempt to improve
1752  * throughput.  The "while" is measured by numbers of attempted frames:
1753  *
1754  * For legacy mode, search for new mode after:
1755  *   480 successful frames, or 160 failed frames
1756  * For high-throughput modes (SISO or MIMO), search for new mode after:
1757  *   4500 successful frames, or 400 failed frames
1758  *
1759  * Mode switch possibilities are (3 for each mode):
1760  *
1761  * For legacy:
1762  *   Change antenna, try SISO (if HT association), try MIMO (if HT association)
1763  * For SISO:
1764  *   Change antenna, try MIMO, try shortened guard interval (SGI)
1765  * For MIMO:
1766  *   Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
1767  *
1768  * When trying a new mode, use the same bit rate as the old/current mode when
1769  * trying antenna switches and shortened guard interval.  When switching to
1770  * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
1771  * for which the expected throughput (under perfect conditions) is about the
1772  * same or slightly better than the actual measured throughput delivered by
1773  * the old/current mode.
1774  *
1775  * Actual throughput can be estimated by multiplying the expected throughput
1776  * by the success ratio (successful / attempted tx frames).  Frame size is
1777  * not considered in this calculation; it assumes that frame size will average
1778  * out to be fairly consistent over several samples.  The following are
1779  * metric values for expected throughput assuming 100% success ratio.
1780  * Only G band has support for CCK rates:
1781  *
1782  *           RATE:  1    2    5   11    6   9   12   18   24   36   48   54   60

1794  *
1795  * After the new mode has been tried for a short while (minimum of 6 failed
1796  * frames or 8 successful frames), compare success ratio and actual throughput
1797  * estimate of the new mode with the old.  If either is better with the new
1798  * mode, continue to use the new mode.

1800  * Continue comparing modes until all 3 possibilities have been tried.

1802  * mode.  After trying all 3, a best mode is found.  Continue to use this mode
1803  * for the longer "while" described above (e.g. 480 successful frames for
1804  * legacy), and then repeat the search process.

2314  *
2315  * The hardware scan command is very powerful; the driver can set it up to
2316  * maintain (relatively) normal network traffic while doing a scan in the
2317  * background.  The max_out_time and suspend_time control the ratio of how
2318  * long the device stays on an associated network channel ("service channel")
2319  * vs. how long it's away from the service channel, i.e. tuned to other channels
2320  * for scanning.
2321  *
2322  * max_out_time is the max time off-channel (in usec), and suspend_time
2323  * is how long (in "extended beacon" format) that the scan is "suspended"
2324  * after returning to the service channel.  That is, suspend_time is the
2325  * time that we stay on the service channel, doing normal work, between
2326  * scan segments.  The driver may set these parameters differently to support
2327  * scanning when associated vs. not associated, and light vs. heavy traffic
2328  * loads when associated.
2329  *
2330  * After receiving this command, the device's scan engine does the following;
2331  *
2332  * 1)  Sends SCAN_START notification to driver
2333  * 2)  Checks to see if it has time to do scan for one channel
2334  * 3)  Sends NULL packet, with power-save (PS) bit set to 1,
2335  *     to tell AP that we're going off-channel
2336  * 4)  Tunes to first channel in scan list, does active or passive scan
2337  * 5)  Sends SCAN_RESULT notification to driver
2338  * 6)  Checks to see if it has time to do scan on *next* channel in list
2339  * 7)  Repeats 4-6 until it no longer has time to scan the next channel
2340  *     before max_out_time expires
2341  * 8)  Returns to service channel
2342  * 9)  Sends NULL packet with PS=0 to tell AP that we're back
2343  * 10) Stays on service channel until suspend_time expires
2344  * 11) Repeats entire process 2-10 until list is complete
2345  * 12) Sends SCAN_COMPLETE notification
2346  *
2347  * For fast, efficient scans, the scan command also has support for staying on
2348  * a channel for just a short time, if doing active scanning and getting no
2349  * responses to the transmitted probe request.  This time is controlled by
2350  * quiet_time, and the number of received packets below which a channel is
2351  * considered "quiet" is controlled by quiet_plcp_threshold.
2352  *
2353  * For active scanning on channels that have regulatory restrictions against
2354  * blindly transmitting, the scan can listen before transmitting, to make sure
2355  * that there is already legitimate activity on the channel.  If enough
2356  * packets are cleanly received on the channel (controlled by good_CRC_th,
2357  * typical value 1), the scan engine starts transmitting probe requests.
2358  *
2359  * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
2360  *
2361  * To avoid uCode errors, see timing restrictions described under
2362  * struct iwl_scan_channel.

2844 /**
2845  * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
2846  *
2847  * This command sets up the Rx signal detector for a sensitivity level that
2848  * is high enough to lock onto all signals within the associated network,
2849  * but low enough to ignore signals that are below a certain threshold, so as
2850  * not to have too many "false alarms".  False alarms are signals that the
2851  * Rx DSP tries to lock onto, but then discards after determining that they
2852  * are noise.
2853  *
2854  * The optimum number of false alarms is between 5 and 50 per 200 TUs
2855  * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
2856  * time listening, not transmitting).  Driver must adjust sensitivity so that
2857  * the ratio of actual false alarms to actual Rx time falls within this range.
2858  *
2859  * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
2860  * received beacon.  These provide information to the driver to analyze the
2861  * sensitivity.  Don't analyze statistics that come in from scanning, or any
2862  * other non-associated-network source.  Pertinent statistics include:
2863  *
2864  * From "general" statistics (struct statistics_rx_non_phy):
2865  *
2866  * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
2867  *   Measure of energy of desired signal.  Used for establishing a level
2868  *   below which the device does not detect signals.
2869  *
2870  * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
2871  *   Measure of background noise in silent period after beacon.
2872  *
2873  * channel_load
2874  *   uSecs of actual Rx time during beacon period (varies according to
2875  *   how much time was spent transmitting).
2876  *
2877  * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
2878  *
2879  * false_alarm_cnt
2880  *   Signal locks abandoned early (before phy-level header).
2881  *
2882  * plcp_err
2883  *   Signal locks abandoned late (during phy-level header).
2884  *
2885  * NOTE:  Both false_alarm_cnt and plcp_err increment monotonically from
2886  *        beacon to beacon, i.e. each value is an accumulation of all errors
2887  *        before and including the latest beacon.  Values will wrap around to 0
2888  *        after counting up to 2^32 - 1.  Driver must differentiate vs.
2889  *        previous beacon's values to determine # false alarms in the current
2890  *        beacon period.
2891  *
2892  * Total number of false alarms = false_alarms + plcp_errs
2893  *
2894  * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
2895  * (notice that the start points for OFDM are at or close to settings for
2896  * maximum sensitivity):
2897  *
2898  *                                             START  /  MIN  /  MAX
2899  *   HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX          90   /   85  /  120
2900  *   HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX     170   /  170  /  210
2901  *   HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX         105   /  105  /  140
2902  *   HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX     220   /  220  /  270
2903  *
2904  *   If actual rate of OFDM false alarms (+ plcp_errors) is too high
2905  *   (greater than 50 for each 204.8 msecs listening), reduce sensitivity
2906  *   by *adding* 1 to all 4 of the table entries above, up to the max for
2907  *   each entry.  Conversely, if false alarm rate is too low (less than 5
2908  *   for each 204.8 msecs listening), *subtract* 1 from each entry to
2909  *   increase sensitivity.
2910  *
2911  * For CCK sensitivity, keep track of the following:
2912  *
2913  *   1).  20-beacon history of maximum background noise, indicated by
2914  *        (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
2915  *        3 receivers.  For any given beacon, the "silence reference" is
2916  *        the maximum of last 60 samples (20 beacons * 3 receivers).
2917  *
2918  *   2).  10-beacon history of strongest signal level, as indicated
2919  *        by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
2920  *        i.e. the strength of the signal through the best receiver at the
2921  *        moment.  These measurements are "upside down", with lower values
2922  *        for stronger signals, so max energy will be *minimum* value.
2923  *
2924  *        Then for any given beacon, the driver must determine the *weakest*
2925  *        of the strongest signals; this is the minimum level that needs to be
2926  *        successfully detected, when using the best receiver at the moment.
2927  *        "Max cck energy" is the maximum (higher value means lower energy!)
2928  *        of the last 10 minima.  Once this is determined, driver must add
2929  *        a little margin by adding "6" to it.
2930  *
2931  *   3).  Number of consecutive beacon periods with too few false alarms.
2932  *        Reset this to 0 at the first beacon period that falls within the
2933  *        "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
2934  *
2935  * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd

2942  *
2943  *   If actual rate of CCK false alarms (+ plcp_errors) is too high
2944  *   (greater than 50 for each 204.8 msecs listening), method for reducing
2945  *   sensitivity is:
2946  *
2947  *   1)  *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2948  *       up to max 400.
2949  *
2950  *   2)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
2951  *       sensitivity has been reduced a significant amount; bring it up to
2952  *       a moderate 161.  Otherwise, *add* 3, up to max 200.
2953  *
2954  *   3)  a)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
2955  *       sensitivity has been reduced only a moderate or small amount;
2956  *       *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
2957  *       down to min 0.  Otherwise (if gain has been significantly reduced),
2958  *       don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
2959  *
2960  *       b)  Save a snapshot of the "silence reference".
2961  *
2962  *   If actual rate of CCK false alarms (+ plcp_errors) is too low
2963  *   (less than 5 for each 204.8 msecs listening), method for increasing
2964  *   sensitivity is used only if:
2965  *
2966  *   1a)  Previous beacon did not have too many false alarms
2967  *   1b)  AND difference between previous "silence reference" and current
2968  *        "silence reference" (prev - current) is 2 or more,
2969  *   OR 2)  100 or more consecutive beacon periods have had rate of
2970  *          less than 5 false alarms per 204.8 milliseconds rx time.
2971  *
2972  *   Method for increasing sensitivity:
2973  *
2974  *   1)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
2975  *       down to min 125.
2976  *
2977  *   2)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2978  *       down to min 200.
2979  *
2980  *   3)  *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
2981  *
2982  *   If actual rate of CCK false alarms (+ plcp_errors) is within good range
2983  *   (between 5 and 50 for each 204.8 msecs listening):
2984  *
2985  *   1)  Save a snapshot of the silence reference.
2986  *
2987  *   2)  If previous beacon had too many CCK false alarms (+ plcp_errors),
2988  *       give some extra margin to energy threshold by *subtracting* 8
2989  *       from value in HD_MIN_ENERGY_CCK_DET_INDEX.
2990  *
2991  *   For all cases (too few, too many, good range), make sure that the CCK
2992  *   detection threshold (energy) is below the energy level for robust
2993  *   detection over the past 10 beacon periods, the "Max cck energy".
2994  *   Lower values mean higher energy; this means making sure that the value
2995  *   in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

3090  * This command sets the relative gains of agn device's 3 radio receiver chains.
3091  *
3092  * After the first association, driver should accumulate signal and noise

3099  * Driver should determine which antennas are actually connected, by comparing
3100  * average beacon signal levels for the 3 Rx chains.  Accumulate (add) the

3107  * strongest.  If any signal is more than 15 dB (times 20, unless you
3108  * divide the accumulated values by 20) below the strongest, the driver
3109  * considers that antenna to be disconnected, and should not try to use that

3111  * driver should declare the stronger one as connected, and attempt to use it
3112  * (A and B are the only 2 Tx chains!).
3113  *
3114  *
3115  * RX BALANCE:
3116  *
3117  * Driver should balance the 3 receivers (but just the ones that are connected
3118  * to antennas, see above) for gain, by comparing the average signal levels
3119  * detected during the silence after each beacon (background noise).
3120  * Accumulate (add) the following values over 20 beacons, one accumulator for
3121  * each of the chains a/b/c, from struct statistics_rx_non_phy:
3122  *
3123  * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
3124  *
3125  * Find the weakest background noise level from among a/b/c.  This Rx chain
3126  * will be the reference, with 0 gain adjustment.  Attenuate other channels by
3127  * finding noise difference:
3128  *
3129  * (accum_noise[i] - accum_noise[reference]) / 30
3130  *
3131  * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
3132  * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
