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

417 * __le32 event_id; range 0 - 1500
418 * __le32 timestamp; low 32 bits of TSF (of network, if associated)
419 * __le32 data; event_id-specific data value
420 *
421 * Entries without timestamps contain only event_id and data.
422 *
423 * 2) error_event_table_ptr indicates base of the error log. This contains

426 *
427 * __le32 valid; (nonzero) valid, (0) log is empty
428 * __le32 error_id; type of error

568 *
569 * NOTE: When tuning to a new channel, driver must set the
570 * RXON_FILTER_ASSOC_MSK to 0. This will clear station-dependent
571 * info within the device, including the station tables, tx retry
572 * rate tables, and txpower tables. Driver must build a new station
573 * table and txpower table before transmitting anything on the RXON
574 * channel.
575 *
576 * NOTE: All RXONs wipe clean the internal txpower table. Driver must
577 * issue a new REPLY_TX_PWR_TABLE_CMD after each REPLY_RXON (0x10),

1787 * is high enough to lock onto all signals within the associated network,
1788 * but low enough to ignore signals that are below a certain threshold, so as

1791 * are noise.
1792 *
1793 * The optimum number of false alarms is between 5 and 50 per 200 TUs
1794 * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
1795 * time listening, not transmitting). Driver must adjust sensitivity so that
1796 * the ratio of actual false alarms to actual Rx time falls within this range.
1797 *
1798 * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
1799 * received beacon. These provide information to the driver to analyze the
1800 * sensitivity. Don't analyze statistics that come in from scanning, or any

1806 * Measure of energy of desired signal. Used for establishing a level
1807 * below which the device does not detect signals.
1808 *
1809 * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
1810 * Measure of background noise in silent period after beacon.
1811 *
1812 * channel_load
1813 * uSecs of actual Rx time during beacon period (varies according to
1814 * how much time was spent transmitting).
1815 *
1816 * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
1817 *
1818 * false_alarm_cnt
1819 * Signal locks abandoned early (before phy-level header).
1820 *
1821 * plcp_err
1822 * Signal locks abandoned late (during phy-level header).
1823 *
1824 * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
1825 * beacon to beacon, i.e. each value is an accumulation of all errors
1826 * before and including the latest beacon. Values will wrap around to 0
1827 * after counting up to 2^32 - 1. Driver must differentiate vs.
1828 * previous beacon's values to determine # false alarms in the current
1829 * beacon period.
1830 *
1831 * Total number of false alarms = false_alarms + plcp_errs
1832 *
1833 * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
1834 * (notice that the start points for OFDM are at or close to settings for
1835 * maximum sensitivity):
1836 *
1837 * START / MIN / MAX
1838 * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
1839 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
1840 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
1841 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
1842 *
1843 * If actual rate of OFDM false alarms (+ plcp_errors) is too high
1844 * (greater than 50 for each 204.8 msecs listening), reduce sensitivity
1845 * by *adding* 1 to all 4 of the table entries above, up to the max for
1846 * each entry. Conversely, if false alarm rate is too low (less than 5
1847 * for each 204.8 msecs listening), *subtract* 1 from each entry to
1848 * increase sensitivity.
1849 *
1850 * For CCK sensitivity, keep track of the following:
1851 *
1852 * 1). 20-beacon history of maximum background noise, indicated by
1853 * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
1854 * 3 receivers. For any given beacon, the "silence reference" is
1855 * the maximum of last 60 samples (20 beacons * 3 receivers).
1856 *
1857 * 2). 10-beacon history of strongest signal level, as indicated
1858 * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
1859 * i.e. the strength of the signal through the best receiver at the
1860 * moment. These measurements are "upside down", with lower values
1861 * for stronger signals, so max energy will be *minimum* value.
1862 *
1863 * Then for any given beacon, the driver must determine the *weakest*
1864 * of the strongest signals; this is the minimum level that needs to be
1865 * successfully detected, when using the best receiver at the moment.
1866 * "Max cck energy" is the maximum (higher value means lower energy!)
1867 * of the last 10 minima. Once this is determined, driver must add
1868 * a little margin by adding "6" to it.
1869 *
1870 * 3). Number of consecutive beacon periods with too few false alarms.
1871 * Reset this to 0 at the first beacon period that falls within the
1872 * "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
1873 *
1874 * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
1875 * (notice that the start points for CCK are at maximum sensitivity):
1876 *
1877 * START / MIN / MAX
1878 * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
1879 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
1880 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
1881 *
1882 * If actual rate of CCK false alarms (+ plcp_errors) is too high
1883 * (greater than 50 for each 204.8 msecs listening), method for reducing
1884 * sensitivity is:
1885 *
1886 * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
1887 * up to max 400.
1888 *
1889 * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
1890 * sensitivity has been reduced a significant amount; bring it up to
1891 * a moderate 161. Otherwise, *add* 3, up to max 200.
1892 *
1893 * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
1894 * sensitivity has been reduced only a moderate or small amount;
1895 * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
1896 * down to min 0. Otherwise (if gain has been significantly reduced),
1897 * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
1898 *
1899 * b) Save a snapshot of the "silence reference".
1900 *
1901 * If actual rate of CCK false alarms (+ plcp_errors) is too low
1902 * (less than 5 for each 204.8 msecs listening), method for increasing
1903 * sensitivity is used only if:
1904 *
1905 * 1a) Previous beacon did not have too many false alarms
1906 * 1b) AND difference between previous "silence reference" and current
1907 * "silence reference" (prev - current) is 2 or more,
1908 * OR 2) 100 or more consecutive beacon periods have had rate of
1909 * less than 5 false alarms per 204.8 milliseconds rx time.
1910 *
1911 * Method for increasing sensitivity:
1912 *
1913 * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
1914 * down to min 125.
1915 *
1916 * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
1917 * down to min 200.
1918 *
1919 * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
1920 *
1921 * If actual rate of CCK false alarms (+ plcp_errors) is within good range
1922 * (between 5 and 50 for each 204.8 msecs listening):
1923 *
1924 * 1) Save a snapshot of the silence reference.
1925 *
1926 * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
1927 * give some extra margin to energy threshold by *subtracting* 8
1928 * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
1929 *
1930 * For all cases (too few, too many, good range), make sure that the CCK
1931 * detection threshold (energy) is below the energy level for robust
1932 * detection over the past 10 beacon periods, the "Max cck energy".
1933 * Lower values mean higher energy; this means making sure that the value
1934 * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".
1935 *
1936 * Driver should set the following entries to fixed values:
1937 *
1938 * HD_MIN_ENERGY_OFDM_DET_INDEX 100
1939 * HD_BARKER_CORR_TH_ADD_MIN_INDEX 190
1940 * HD_BARKER_CORR_TH_ADD_MIN_MRC_INDEX 390
1941 * HD_OFDM_ENERGY_TH_IN_INDEX 62

1978 * REPLY_PHY_CALIBRATION_CMD = 0xb0 (command, has simple generic response)
1979 *
1980 * This command sets the relative gains of 4965's 3 radio receiver chains.
1981 *
1982 * After the first association, driver should accumulate signal and noise
1983 * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20
1984 * beacons from the associated network (don't collect statistics that come
1985 * in from scanning, or any other non-network source).
1986 *
1987 * DISCONNECTED ANTENNA:
1988 *
1989 * Driver should determine which antennas are actually connected, by comparing
1990 * average beacon signal levels for the 3 Rx chains. Accumulate (add) the
1991 * following values over 20 beacons, one accumulator for each of the chains
1992 * a/b/c, from struct statistics_rx_non_phy:
1993 *
1994 * beacon_rssi_[abc] & 0x0FF (unsigned, units in dB)
1995 *
1996 * Find the strongest signal from among a/b/c. Compare the other two to the
1997 * strongest. If any signal is more than 15 dB (times 20, unless you
1998 * divide the accumulated values by 20) below the strongest, the driver
1999 * considers that antenna to be disconnected, and should not try to use that
2000 * antenna/chain for Rx or Tx. If both A and B seem to be disconnected,
2001 * driver should declare the stronger one as connected, and attempt to use it
2002 * (A and B are the only 2 Tx chains!).
2003 *
2004 *
2005 * RX BALANCE:
2006 *
2007 * Driver should balance the 3 receivers (but just the ones that are connected
2008 * to antennas, see above) for gain, by comparing the average signal levels
2009 * detected during the silence after each beacon (background noise).
2010 * Accumulate (add) the following values over 20 beacons, one accumulator for
2011 * each of the chains a/b/c, from struct statistics_rx_non_phy:
2012 *
2013 * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
2014 *
2015 * Find the weakest background noise level from among a/b/c. This Rx chain
2016 * will be the reference, with 0 gain adjustment. Attenuate other channels by
2017 * finding noise difference:
2018 *
2019 * (accum_noise[i] - accum_noise[reference]) / 30
2020 *
2021 * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB.
2022 * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the
2023 * driver should limit the difference results to a range of 0-3 (0-4.5 dB),
2024 * and set bit 2 to indicate "reduce gain". The value for the reference
2025 * (weakest) chain should be "0".
2026 *
2027 * diff_gain_[abc] bit fields:
2028 * 2: (1) reduce gain, (0) increase gain
2029 * 1-0: amount of gain, units of 1.5 dB
