1559  * FILLING THE RATE TABLE
1560  *
1561  * Given a particular initial rate and mode, as determined by the rate
1562  * scaling algorithm described below, the Linux driver uses the following
1563  * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
1564  * Link Quality command:
1565  *
1566  *
1567  * 1)  If using High-throughput (HT) (SISO or MIMO) initial rate:
1568  *     a) Use this same initial rate for first 3 entries.
1569  *     b) Find next lower available rate using same mode (SISO or MIMO),
1570  *        use for next 3 entries.  If no lower rate available, switch to
1571  *        legacy mode (no HT40 channel, no MIMO, no short guard interval).
1572  *     c) If using MIMO, set command's mimo_delimiter to number of entries
1573  *        using MIMO (3 or 6).
1574  *     d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
1575  *        no MIMO, no short guard interval), at the next lower bit rate
1576  *        (e.g. if second HT bit rate was 54, try 48 legacy), and follow
1577  *        legacy procedure for remaining table entries.
1578  *
1579  * 2)  If using legacy initial rate:
1580  *     a) Use the initial rate for only one entry.
1581  *     b) For each following entry, reduce the rate to next lower available
1582  *        rate, until reaching the lowest available rate.
1583  *     c) When reducing rate, also switch antenna selection.
1584  *     d) Once lowest available rate is reached, repeat this rate until
1585  *        rate table is filled (16 entries), switching antenna each entry.
1586  *
1587  *
1588  * ACCUMULATING HISTORY
1589  *
1590  * The rate scaling algorithm for agn devices, as implemented in Linux driver,
1591  * uses two sets of frame Tx success history:  One for the current/active
1592  * modulation mode, and one for a speculative/search mode that is being
1593  * attempted. If the speculative mode turns out to be more effective (i.e.
1594  * actual transfer rate is better), then the driver continues to use the
1595  * speculative mode as the new current active mode.
1596  *
1597  * Each history set contains, separately for each possible rate, data for a
1598  * sliding window of the 62 most recent tx attempts at that rate.  The data
1599  * includes a shifting bitmap of success(1)/failure(0), and sums of successful
1600  * and attempted frames, from which the driver can additionally calculate a
1601  * success ratio (success / attempted) and number of failures
1602  * (attempted - success), and control the size of the window (attempted).
1603  * The driver uses the bit map to remove successes from the success sum, as
1604  * the oldest tx attempts fall out of the window.
1605  *
1606  * When the agn device makes multiple tx attempts for a given frame, each
1607  * attempt might be at a different rate, and have different modulation
1608  * characteristics (e.g. antenna, fat channel, short guard interval), as set
1609  * up in the rate scaling table in the Link Quality command.  The driver must
1610  * determine which rate table entry was used for each tx attempt, to determine
1611  * which rate-specific history to update, and record only those attempts that
1612  * match the modulation characteristics of the history set.
1613  *
1614  * When using block-ack (aggregation), all frames are transmitted at the same
1615  * rate, since there is no per-attempt acknowledgment from the destination
1616  * station.  The Tx response struct iwl_tx_resp indicates the Tx rate in
1617  * rate_n_flags field.  After receiving a block-ack, the driver can update
1618  * history for the entire block all at once.
1619  *
1620  *
1621  * FINDING BEST STARTING RATE:
1622  *
1623  * When working with a selected initial modulation mode (see below), the
1624  * driver attempts to find a best initial rate.  The initial rate is the
1625  * first entry in the Link Quality command's rate table.
1626  *
1627  * 1)  Calculate actual throughput (success ratio * expected throughput, see
1628  *     table below) for current initial rate.  Do this only if enough frames
1629  *     have been attempted to make the value meaningful:  at least 6 failed
1630  *     tx attempts, or at least 8 successes.  If not enough, don't try rate
1631  *     scaling yet.
1632  *
1633  * 2)  Find available rates adjacent to current initial rate.  Available means:
1634  *     a)  supported by hardware &&
1635  *     b)  supported by association &&
1636  *     c)  within any constraints selected by user
1637  *
1638  * 3)  Gather measured throughputs for adjacent rates.  These might not have
1639  *     enough history to calculate a throughput.  That's okay, we might try
1640  *     using one of them anyway!
1641  *
1642  * 4)  Try decreasing rate if, for current rate:
1643  *     a)  success ratio is < 15% ||
1644  *     b)  lower adjacent rate has better measured throughput ||
1645  *     c)  higher adjacent rate has worse throughput, and lower is unmeasured
1646  *
1647  *     As a sanity check, if decrease was determined above, leave rate
1648  *     unchanged if:
1649  *     a)  lower rate unavailable
1650  *     b)  success ratio at current rate > 85% (very good)
1651  *     c)  current measured throughput is better than expected throughput
1652  *         of lower rate (under perfect 100% tx conditions, see table below)
1653  *
1654  * 5)  Try increasing rate if, for current rate:
1655  *     a)  success ratio is < 15% ||
1656  *     b)  both adjacent rates' throughputs are unmeasured (try it!) ||
1657  *     b)  higher adjacent rate has better measured throughput ||
1658  *     c)  lower adjacent rate has worse throughput, and higher is unmeasured
1659  *
1660  *     As a sanity check, if increase was determined above, leave rate
1661  *     unchanged if:
1662  *     a)  success ratio at current rate < 70%.  This is not particularly
1663  *         good performance; higher rate is sure to have poorer success.
1664  *
1665  * 6)  Re-evaluate the rate after each tx frame.  If working with block-
1666  *     acknowledge, history and statistics may be calculated for the entire
1667  *     block (including prior history that fits within the history windows),
1668  *     before re-evaluation.
1669  *
1670  * FINDING BEST STARTING MODULATION MODE:
1671  *
1672  * After working with a modulation mode for a "while" (and doing rate scaling),
1673  * the driver searches for a new initial mode in an attempt to improve
1674  * throughput.  The "while" is measured by numbers of attempted frames:
1675  *
1676  * For legacy mode, search for new mode after:
1677  *   480 successful frames, or 160 failed frames
1678  * For high-throughput modes (SISO or MIMO), search for new mode after:
1679  *   4500 successful frames, or 400 failed frames
1680  *
1681  * Mode switch possibilities are (3 for each mode):
1682  *
1683  * For legacy:

1687  * For MIMO:
1688  *   Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
1689  *
1690  * When trying a new mode, use the same bit rate as the old/current mode when
1691  * trying antenna switches and shortened guard interval.  When switching to
1692  * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
1693  * for which the expected throughput (under perfect conditions) is about the
1694  * same or slightly better than the actual measured throughput delivered by
1695  * the old/current mode.
1696  *
1697  * Actual throughput can be estimated by multiplying the expected throughput
1698  * by the success ratio (successful / attempted tx frames).  Frame size is
1699  * not considered in this calculation; it assumes that frame size will average
1700  * out to be fairly consistent over several samples.  The following are
1701  * metric values for expected throughput assuming 100% success ratio.

2235  * REPLY_SCAN_CMD = 0x80 (command)
2236  *
2237  * The hardware scan command is very powerful; the driver can set it up to
2238  * maintain (relatively) normal network traffic while doing a scan in the
2239  * background.  The max_out_time and suspend_time control the ratio of how
2240  * long the device stays on an associated network channel ("service channel")
2241  * vs. how long it's away from the service channel, i.e. tuned to other channels
2242  * for scanning.
2243  *
2244  * max_out_time is the max time off-channel (in usec), and suspend_time
2245  * is how long (in "extended beacon" format) that the scan is "suspended"
2246  * after returning to the service channel.  That is, suspend_time is the
2247  * time that we stay on the service channel, doing normal work, between
2248  * scan segments.  The driver may set these parameters differently to support
2249  * scanning when associated vs. not associated, and light vs. heavy traffic
2250  * loads when associated.
2251  *
2252  * After receiving this command, the device's scan engine does the following;
2253  *
2254  * 1)  Sends SCAN_START notification to driver
2255  * 2)  Checks to see if it has time to do scan for one channel
2256  * 3)  Sends NULL packet, with power-save (PS) bit set to 1,
2257  *     to tell AP that we're going off-channel
2258  * 4)  Tunes to first channel in scan list, does active or passive scan
2259  * 5)  Sends SCAN_RESULT notification to driver
2260  * 6)  Checks to see if it has time to do scan on *next* channel in list
2261  * 7)  Repeats 4-6 until it no longer has time to scan the next channel
2262  *     before max_out_time expires
2263  * 8)  Returns to service channel
2264  * 9)  Sends NULL packet with PS=0 to tell AP that we're back
2265  * 10) Stays on service channel until suspend_time expires
2266  * 11) Repeats entire process 2-10 until list is complete
2267  * 12) Sends SCAN_COMPLETE notification
2268  *
2269  * For fast, efficient scans, the scan command also has support for staying on
2270  * a channel for just a short time, if doing active scanning and getting no
2271  * responses to the transmitted probe request.  This time is controlled by
2272  * quiet_time, and the number of received packets below which a channel is
2273  * considered "quiet" is controlled by quiet_plcp_threshold.
2274  *
2275  * For active scanning on channels that have regulatory restrictions against
2276  * blindly transmitting, the scan can listen before transmitting, to make sure
2277  * that there is already legitimate activity on the channel.  If enough
2278  * packets are cleanly received on the channel (controlled by good_CRC_th,
2279  * typical value 1), the scan engine starts transmitting probe requests.
2280  *
2281  * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
2282  *
2283  * To avoid uCode errors, see timing restrictions described under
2284  * struct iwl_scan_channel.

2766 /**
2767  * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
2768  *
2769  * This command sets up the Rx signal detector for a sensitivity level that
2770  * is high enough to lock onto all signals within the associated network,
2771  * but low enough to ignore signals that are below a certain threshold, so as
2772  * not to have too many "false alarms".  False alarms are signals that the
2773  * Rx DSP tries to lock onto, but then discards after determining that they
2774  * are noise.
2775  *
2776  * The optimum number of false alarms is between 5 and 50 per 200 TUs
2777  * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
2778  * time listening, not transmitting).  Driver must adjust sensitivity so that
2779  * the ratio of actual false alarms to actual Rx time falls within this range.
2780  *
2781  * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
2782  * received beacon.  These provide information to the driver to analyze the
2783  * sensitivity.  Don't analyze statistics that come in from scanning, or any
2784  * other non-associated-network source.  Pertinent statistics include:
2785  *
2786  * From "general" statistics (struct statistics_rx_non_phy):
2787  *
2788  * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
2789  *   Measure of energy of desired signal.  Used for establishing a level
2790  *   below which the device does not detect signals.
2791  *
2792  * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
2793  *   Measure of background noise in silent period after beacon.
2794  *
2795  * channel_load
2796  *   uSecs of actual Rx time during beacon period (varies according to
2797  *   how much time was spent transmitting).
2798  *
2799  * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
2800  *
2801  * false_alarm_cnt
2802  *   Signal locks abandoned early (before phy-level header).
2803  *
2804  * plcp_err
2805  *   Signal locks abandoned late (during phy-level header).
2806  *
2807  * NOTE:  Both false_alarm_cnt and plcp_err increment monotonically from
2808  *        beacon to beacon, i.e. each value is an accumulation of all errors
2809  *        before and including the latest beacon.  Values will wrap around to 0
2810  *        after counting up to 2^32 - 1.  Driver must differentiate vs.
2811  *        previous beacon's values to determine # false alarms in the current
2812  *        beacon period.
2813  *
2814  * Total number of false alarms = false_alarms + plcp_errs
2815  *
2816  * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
2817  * (notice that the start points for OFDM are at or close to settings for
2818  * maximum sensitivity):
2819  *
2820  *                                             START  /  MIN  /  MAX
2821  *   HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX          90   /   85  /  120
2822  *   HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX     170   /  170  /  210
2823  *   HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX         105   /  105  /  140
2824  *   HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX     220   /  220  /  270
2825  *
2826  *   If actual rate of OFDM false alarms (+ plcp_errors) is too high
2827  *   (greater than 50 for each 204.8 msecs listening), reduce sensitivity
2828  *   by *adding* 1 to all 4 of the table entries above, up to the max for
2829  *   each entry.  Conversely, if false alarm rate is too low (less than 5
2830  *   for each 204.8 msecs listening), *subtract* 1 from each entry to
2831  *   increase sensitivity.
2832  *
2833  * For CCK sensitivity, keep track of the following:
2834  *
2835  *   1).  20-beacon history of maximum background noise, indicated by
2836  *        (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
2837  *        3 receivers.  For any given beacon, the "silence reference" is
2838  *        the maximum of last 60 samples (20 beacons * 3 receivers).
2839  *
2840  *   2).  10-beacon history of strongest signal level, as indicated
2841  *        by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
2842  *        i.e. the strength of the signal through the best receiver at the
2843  *        moment.  These measurements are "upside down", with lower values
2844  *        for stronger signals, so max energy will be *minimum* value.
2845  *
2846  *        Then for any given beacon, the driver must determine the *weakest*
2847  *        of the strongest signals; this is the minimum level that needs to be
2848  *        successfully detected, when using the best receiver at the moment.
2849  *        "Max cck energy" is the maximum (higher value means lower energy!)
2850  *        of the last 10 minima.  Once this is determined, driver must add
2851  *        a little margin by adding "6" to it.
2852  *
2853  *   3).  Number of consecutive beacon periods with too few false alarms.
2854  *        Reset this to 0 at the first beacon period that falls within the
2855  *        "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
2856  *
2857  * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
2858  * (notice that the start points for CCK are at maximum sensitivity):
2859  *
2860  *                                             START  /  MIN  /  MAX
2861  *   HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX         125   /  125  /  200
2862  *   HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX     200   /  200  /  400
2863  *   HD_MIN_ENERGY_CCK_DET_INDEX                100   /    0  /  100
2864  *
2865  *   If actual rate of CCK false alarms (+ plcp_errors) is too high
2866  *   (greater than 50 for each 204.8 msecs listening), method for reducing
2867  *   sensitivity is:
2868  *
2869  *   1)  *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2870  *       up to max 400.
2871  *
2872  *   2)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
2873  *       sensitivity has been reduced a significant amount; bring it up to
2874  *       a moderate 161.  Otherwise, *add* 3, up to max 200.
2875  *
2876  *   3)  a)  If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
2877  *       sensitivity has been reduced only a moderate or small amount;
2878  *       *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
2879  *       down to min 0.  Otherwise (if gain has been significantly reduced),
2880  *       don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
2881  *
2882  *       b)  Save a snapshot of the "silence reference".
2883  *
2884  *   If actual rate of CCK false alarms (+ plcp_errors) is too low
2885  *   (less than 5 for each 204.8 msecs listening), method for increasing
2886  *   sensitivity is used only if:
2887  *
2888  *   1a)  Previous beacon did not have too many false alarms
2889  *   1b)  AND difference between previous "silence reference" and current
2890  *        "silence reference" (prev - current) is 2 or more,
2891  *   OR 2)  100 or more consecutive beacon periods have had rate of
2892  *          less than 5 false alarms per 204.8 milliseconds rx time.
2893  *
2894  *   Method for increasing sensitivity:
2895  *
2896  *   1)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
2897  *       down to min 125.
2898  *
2899  *   2)  *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2900  *       down to min 200.
2901  *
2902  *   3)  *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
2903  *
2904  *   If actual rate of CCK false alarms (+ plcp_errors) is within good range
2905  *   (between 5 and 50 for each 204.8 msecs listening):
2906  *
2907  *   1)  Save a snapshot of the silence reference.
2908  *
2909  *   2)  If previous beacon had too many CCK false alarms (+ plcp_errors),
2910  *       give some extra margin to energy threshold by *subtracting* 8
2911  *       from value in HD_MIN_ENERGY_CCK_DET_INDEX.
2912  *

3011  *
3012  * This command sets the relative gains of agn device's 3 radio receiver chains.
3013  *
3014  * After the first association, driver should accumulate signal and noise
3015  * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20

3019  * DISCONNECTED ANTENNA:
3020  *
3021  * Driver should determine which antennas are actually connected, by comparing
3022  * average beacon signal levels for the 3 Rx chains.  Accumulate (add) the
3023  * following values over 20 beacons, one accumulator for each of the chains

3025  *
3026  * beacon_rssi_[abc] & 0x0FF (unsigned, units in dB)

3028  * Find the strongest signal from among a/b/c.  Compare the other two to the
3029  * strongest.  If any signal is more than 15 dB (times 20, unless you
3030  * divide the accumulated values by 20) below the strongest, the driver
3031  * considers that antenna to be disconnected, and should not try to use that
3032  * antenna/chain for Rx or Tx.  If both A and B seem to be disconnected,
3033  * driver should declare the stronger one as connected, and attempt to use it
3034  * (A and B are the only 2 Tx chains!).
3035  *
3036  *
3037  * RX BALANCE:
3038  *
3039  * Driver should balance the 3 receivers (but just the ones that are connected
3040  * to antennas, see above) for gain, by comparing the average signal levels
3041  * detected during the silence after each beacon (background noise).
3042  * Accumulate (add) the following values over 20 beacons, one accumulator for
3043  * each of the chains a/b/c, from struct statistics_rx_non_phy:
3044  *
3045  * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
3046  *
3047  * Find the weakest background noise level from among a/b/c.  This Rx chain
3048  * will be the reference, with 0 gain adjustment.  Attenuate other channels by
3049  * finding noise difference:
3050  *
3051  * (accum_noise[i] - accum_noise[reference]) / 30
3052  *
3053  * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
3054  * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
3055  * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
3056  * and set bit 2 to indicate "reduce gain".  The value for the reference
3057  * (weakest) chain should be "0".
