1740 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow
1741 * legacy procedure for remaining table entries.
1743 * 2) If using legacy initial rate:
1744 * a) Use the initial rate for only one entry.
1745 * b) For each following entry, reduce the rate to next lower available
1746 * rate, until reaching the lowest available rate.
1747 * c) When reducing rate, also switch antenna selection.
1748 * d) Once lowest available rate is reached, repeat this rate until
1749 * rate table is filled (16 entries), switching antenna each entry.
1752 * ACCUMULATING HISTORY
1754 * The rate scaling algorithm for 4965, as implemented in Linux driver, uses
1755 * two sets of frame Tx success history: One for the current/active modulation
1756 * mode, and one for a speculative/search mode that is being attempted. If the
1757 * speculative mode turns out to be more effective (i.e. actual transfer
1758 * rate is better), then the driver continues to use the speculative mode
1759 * as the new current active mode.
1761 * Each history set contains, separately for each possible rate, data for a
1762 * sliding window of the 62 most recent tx attempts at that rate. The data
1763 * includes a shifting bitmap of success(1)/failure(0), and sums of successful
1764 * and attempted frames, from which the driver can additionally calculate a
1765 * success ratio (success / attempted) and number of failures
1766 * (attempted - success), and control the size of the window (attempted).
1767 * The driver uses the bit map to remove successes from the success sum, as
1768 * the oldest tx attempts fall out of the window.
1770 * When the 4965 makes multiple tx attempts for a given frame, each attempt
1771 * might be at a different rate, and have different modulation characteristics
1772 * (e.g. antenna, fat channel, short guard interval), as set up in the rate
1773 * scaling table in the Link Quality command. The driver must determine
1774 * which rate table entry was used for each tx attempt, to determine which
1775 * rate-specific history to update, and record only those attempts that
1776 * match the modulation characteristics of the history set.
1778 * When using block-ack (aggregation), all frames are transmitted at the same
1779 * rate, since there is no per-attempt acknowledgment from the destination
1780 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in
1781 * rate_n_flags field. After receiving a block-ack, the driver can update
1782 * history for the entire block all at once.
1785 * FINDING BEST STARTING RATE:
1787 * When working with a selected initial modulation mode (see below), the
1788 * driver attempts to find a best initial rate. The initial rate is the
1789 * first entry in the Link Quality command's rate table.
1791 * 1) Calculate actual throughput (success ratio * expected throughput, see
1792 * table below) for current initial rate. Do this only if enough frames
1793 * have been attempted to make the value meaningful: at least 6 failed
1794 * tx attempts, or at least 8 successes. If not enough, don't try rate
1797 * 2) Find available rates adjacent to current initial rate. Available means:
1798 * a) supported by hardware &&
1799 * b) supported by association &&
1800 * c) within any constraints selected by user
1802 * 3) Gather measured throughputs for adjacent rates. These might not have
1803 * enough history to calculate a throughput. That's okay, we might try
1804 * using one of them anyway!
1806 * 4) Try decreasing rate if, for current rate:
1807 * a) success ratio is < 15% ||
1808 * b) lower adjacent rate has better measured throughput ||
1809 * c) higher adjacent rate has worse throughput, and lower is unmeasured
1811 * As a sanity check, if decrease was determined above, leave rate
1813 * a) lower rate unavailable
1814 * b) success ratio at current rate > 85% (very good)
1815 * c) current measured throughput is better than expected throughput
1816 * of lower rate (under perfect 100% tx conditions, see table below)
1818 * 5) Try increasing rate if, for current rate:
1819 * a) success ratio is < 15% ||
1820 * b) both adjacent rates' throughputs are unmeasured (try it!) ||
1821 * b) higher adjacent rate has better measured throughput ||
1822 * c) lower adjacent rate has worse throughput, and higher is unmeasured
1824 * As a sanity check, if increase was determined above, leave rate
1826 * a) success ratio at current rate < 70%. This is not particularly
1827 * good performance; higher rate is sure to have poorer success.
1829 * 6) Re-evaluate the rate after each tx frame. If working with block-
1830 * acknowledge, history and statistics may be calculated for the entire
1831 * block (including prior history that fits within the history windows),
1832 * before re-evaluation.
1834 * FINDING BEST STARTING MODULATION MODE:
1836 * After working with a modulation mode for a "while" (and doing rate scaling),
1837 * the driver searches for a new initial mode in an attempt to improve
1838 * throughput. The "while" is measured by numbers of attempted frames:
1840 * For legacy mode, search for new mode after:
1841 * 480 successful frames, or 160 failed frames
1842 * For high-throughput modes (SISO or MIMO), search for new mode after:
1843 * 4500 successful frames, or 400 failed frames
1845 * Mode switch possibilities are (3 for each mode):
1848 * Change antenna, try SISO (if HT association), try MIMO (if HT association)
1850 * Change antenna, try MIMO, try shortened guard interval (SGI)
1852 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
1854 * When trying a new mode, use the same bit rate as the old/current mode when
1855 * trying antenna switches and shortened guard interval. When switching to
1856 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
1857 * for which the expected throughput (under perfect conditions) is about the
1858 * same or slightly better than the actual measured throughput delivered by
1859 * the old/current mode.
1861 * Actual throughput can be estimated by multiplying the expected throughput
1862 * by the success ratio (successful / attempted tx frames). Frame size is
1863 * not considered in this calculation; it assumes that frame size will average
1864 * out to be fairly consistent over several samples. The following are
1865 * metric values for expected throughput assuming 100% success ratio.
1866 * Only G band has support for CCK rates:
1868 * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60
1870 * G: 7 13 35 58 40 57 72 98 121 154 177 186 186
1871 * A: 0 0 0 0 40 57 72 98 121 154 177 186 186
1872 * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202
1873 * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211
1874 * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251
1875 * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257
1876 * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257
1877 * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264
1878 * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289
1879 * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293
1881 * After the new mode has been tried for a short while (minimum of 6 failed
1882 * frames or 8 successful frames), compare success ratio and actual throughput
1883 * estimate of the new mode with the old. If either is better with the new
1884 * mode, continue to use the new mode.
1886 * Continue comparing modes until all 3 possibilities have been tried.
1887 * If moving from legacy to HT, try all 3 possibilities from the new HT
1888 * mode. After trying all 3, a best mode is found. Continue to use this mode
1889 * for the longer "while" described above (e.g. 480 successful frames for
1890 * legacy), and then repeat the search process.

2221 * The hardware scan command is very powerful; the driver can set it up to
2222 * maintain (relatively) normal network traffic while doing a scan in the
2223 * background. The max_out_time and suspend_time control the ratio of how
2224 * long the device stays on an associated network channel ("service channel")
2225 * vs. how long it's away from the service channel, i.e. tuned to other channels
2228 * max_out_time is the max time off-channel (in usec), and suspend_time
2229 * is how long (in "extended beacon" format) that the scan is "suspended"
2230 * after returning to the service channel. That is, suspend_time is the
2231 * time that we stay on the service channel, doing normal work, between
2232 * scan segments. The driver may set these parameters differently to support
2233 * scanning when associated vs. not associated, and light vs. heavy traffic
2234 * loads when associated.
2236 * After receiving this command, the device's scan engine does the following;
2238 * 1) Sends SCAN_START notification to driver
2239 * 2) Checks to see if it has time to do scan for one channel
2240 * 3) Sends NULL packet, with power-save (PS) bit set to 1,
2241 * to tell AP that we're going off-channel
2242 * 4) Tunes to first channel in scan list, does active or passive scan
2243 * 5) Sends SCAN_RESULT notification to driver
2244 * 6) Checks to see if it has time to do scan on *next* channel in list
2245 * 7) Repeats 4-6 until it no longer has time to scan the next channel
2246 * before max_out_time expires
2247 * 8) Returns to service channel
2248 * 9) Sends NULL packet with PS=0 to tell AP that we're back
2249 * 10) Stays on service channel until suspend_time expires
2250 * 11) Repeats entire process 2-10 until list is complete
2251 * 12) Sends SCAN_COMPLETE notification
2253 * For fast, efficient scans, the scan command also has support for staying on
2254 * a channel for just a short time, if doing active scanning and getting no
2255 * responses to the transmitted probe request. This time is controlled by
2256 * quiet_time, and the number of received packets below which a channel is

2631 * 1) Tx power (depends on temperature), described elsewhere
2632 * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
2633 * 3) Receiver sensitivity (to optimize signal detection)
2635 *****************************************************************************/
2638 * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
2640 * This command sets up the Rx signal detector for a sensitivity level that
2641 * is high enough to lock onto all signals within the associated network,
2642 * but low enough to ignore signals that are below a certain threshold, so as
2643 * not to have too many "false alarms". False alarms are signals that the
2644 * Rx DSP tries to lock onto, but then discards after determining that they
2647 * The optimum number of false alarms is between 5 and 50 per 200 TUs
2648 * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
2649 * time listening, not transmitting). Driver must adjust sensitivity so that
2650 * the ratio of actual false alarms to actual Rx time falls within this range.
2652 * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
2653 * received beacon. These provide information to the driver to analyze the
2654 * sensitivity. Don't analyze statistics that come in from scanning, or any
2655 * other non-associated-network source. Pertinent statistics include:
2657 * From "general" statistics (struct statistics_rx_non_phy):
2659 * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
2660 * Measure of energy of desired signal. Used for establishing a level
2661 * below which the device does not detect signals.
2663 * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
2664 * Measure of background noise in silent period after beacon.
2667 * uSecs of actual Rx time during beacon period (varies according to
2668 * how much time was spent transmitting).
2670 * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
2673 * Signal locks abandoned early (before phy-level header).
2676 * Signal locks abandoned late (during phy-level header).
2678 * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
2679 * beacon to beacon, i.e. each value is an accumulation of all errors
2680 * before and including the latest beacon. Values will wrap around to 0
2681 * after counting up to 2^32 - 1. Driver must differentiate vs.
2682 * previous beacon's values to determine # false alarms in the current
2685 * Total number of false alarms = false_alarms + plcp_errs
2687 * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
2688 * (notice that the start points for OFDM are at or close to settings for
2689 * maximum sensitivity):
2692 * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
2693 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
2694 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
2695 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
2697 * If actual rate of OFDM false alarms (+ plcp_errors) is too high
2698 * (greater than 50 for each 204.8 msecs listening), reduce sensitivity
2699 * by *adding* 1 to all 4 of the table entries above, up to the max for
2700 * each entry. Conversely, if false alarm rate is too low (less than 5
2701 * for each 204.8 msecs listening), *subtract* 1 from each entry to
2702 * increase sensitivity.
2704 * For CCK sensitivity, keep track of the following:
2706 * 1). 20-beacon history of maximum background noise, indicated by
2707 * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
2708 * 3 receivers. For any given beacon, the "silence reference" is
2709 * the maximum of last 60 samples (20 beacons * 3 receivers).
2711 * 2). 10-beacon history of strongest signal level, as indicated
2712 * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
2713 * i.e. the strength of the signal through the best receiver at the
2714 * moment. These measurements are "upside down", with lower values
2715 * for stronger signals, so max energy will be *minimum* value.
2717 * Then for any given beacon, the driver must determine the *weakest*
2718 * of the strongest signals; this is the minimum level that needs to be
2719 * successfully detected, when using the best receiver at the moment.
2720 * "Max cck energy" is the maximum (higher value means lower energy!)
2721 * of the last 10 minima. Once this is determined, driver must add
2722 * a little margin by adding "6" to it.
2724 * 3). Number of consecutive beacon periods with too few false alarms.
2725 * Reset this to 0 at the first beacon period that falls within the
2726 * "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
2728 * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
2729 * (notice that the start points for CCK are at maximum sensitivity):
2732 * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
2733 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
2734 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
2736 * If actual rate of CCK false alarms (+ plcp_errors) is too high
2737 * (greater than 50 for each 204.8 msecs listening), method for reducing
2740 * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2743 * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
2744 * sensitivity has been reduced a significant amount; bring it up to
2745 * a moderate 161. Otherwise, *add* 3, up to max 200.
2747 * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
2748 * sensitivity has been reduced only a moderate or small amount;
2749 * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
2750 * down to min 0. Otherwise (if gain has been significantly reduced),
2751 * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
2753 * b) Save a snapshot of the "silence reference".
2755 * If actual rate of CCK false alarms (+ plcp_errors) is too low
2756 * (less than 5 for each 204.8 msecs listening), method for increasing
2757 * sensitivity is used only if:
2759 * 1a) Previous beacon did not have too many false alarms
2760 * 1b) AND difference between previous "silence reference" and current
2761 * "silence reference" (prev - current) is 2 or more,
2762 * OR 2) 100 or more consecutive beacon periods have had rate of
2763 * less than 5 false alarms per 204.8 milliseconds rx time.
2765 * Method for increasing sensitivity:
2767 * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
2770 * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2773 * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
2775 * If actual rate of CCK false alarms (+ plcp_errors) is within good range
2776 * (between 5 and 50 for each 204.8 msecs listening):
2778 * 1) Save a snapshot of the silence reference.
2780 * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
2781 * give some extra margin to energy threshold by *subtracting* 8
2782 * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
2784 * For all cases (too few, too many, good range), make sure that the CCK
2785 * detection threshold (energy) is below the energy level for robust
2786 * detection over the past 10 beacon periods, the "Max cck energy".
2787 * Lower values mean higher energy; this means making sure that the value
2788 * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".
2790 * Driver should set the following entries to fixed values:

2832 * REPLY_PHY_CALIBRATION_CMD = 0xb0 (command, has simple generic response)
2834 * This command sets the relative gains of 4965's 3 radio receiver chains.
2836 * After the first association, driver should accumulate signal and noise
2837 * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20
2838 * beacons from the associated network (don't collect statistics that come
2839 * in from scanning, or any other non-network source).
2841 * DISCONNECTED ANTENNA:
2843 * Driver should determine which antennas are actually connected, by comparing
2844 * average beacon signal levels for the 3 Rx chains. Accumulate (add) the
2845 * following values over 20 beacons, one accumulator for each of the chains
2846 * a/b/c, from struct statistics_rx_non_phy:
2848 * beacon_rssi_[abc] & 0x0FF (unsigned, units in dB)
2850 * Find the strongest signal from among a/b/c. Compare the other two to the
2851 * strongest. If any signal is more than 15 dB (times 20, unless you
2852 * divide the accumulated values by 20) below the strongest, the driver
2853 * considers that antenna to be disconnected, and should not try to use that
2854 * antenna/chain for Rx or Tx. If both A and B seem to be disconnected,
2855 * driver should declare the stronger one as connected, and attempt to use it
2856 * (A and B are the only 2 Tx chains!).
2861 * Driver should balance the 3 receivers (but just the ones that are connected
2862 * to antennas, see above) for gain, by comparing the average signal levels
2863 * detected during the silence after each beacon (background noise).
2864 * Accumulate (add) the following values over 20 beacons, one accumulator for
2865 * each of the chains a/b/c, from struct statistics_rx_non_phy:
2867 * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
2869 * Find the weakest background noise level from among a/b/c. This Rx chain
2870 * will be the reference, with 0 gain adjustment. Attenuate other channels by
2871 * finding noise difference:
2873 * (accum_noise[i] - accum_noise[reference]) / 30
2875 * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
2876 * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
2877 * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
2878 * and set bit 2 to indicate "reduce gain". The value for the reference
2879 * (weakest) chain should be "0".
2881 * diff_gain_[abc] bit fields:
2882 * 2: (1) reduce gain, (0) increase gain
2883 * 1-0: amount of gain, units of 1.5 dB
