347 * uCode issues this "alive" notification once the runtime image is ready

349 * notification that the driver will receive after rebooting uCode;
350 * this "alive" is indicated by subtype field != 9.
352 * See comments documenting "BSM" (bootstrap state machine).
354 * This response includes two pointers to structures within the device's
355 * data SRAM (access via HBUS_TARG_MEM_* regs) that are useful for debugging:
357 * 1) log_event_table_ptr indicates base of the event log. This traces
358 * a 256-entry history of uCode execution within a circular buffer.
359 * Its header format is:
361 * __le32 log_size; log capacity (in number of entries)
362 * __le32 type; (1) timestamp with each entry, (0) no timestamp
363 * __le32 wraps; # times uCode has wrapped to top of circular buffer
364 * __le32 write_index; next circular buffer entry that uCode would fill
366 * The header is followed by the circular buffer of log entries. Entries
367 * with timestamps have the following format:
369 * __le32 event_id; range 0 - 1500
370 * __le32 timestamp; low 32 bits of TSF (of network, if associated)
371 * __le32 data; event_id-specific data value
373 * Entries without timestamps contain only event_id and data.
376 * 2) error_event_table_ptr indicates base of the error log. This contains
377 * information about any uCode error that occurs. For agn, the format
378 * of the error log is defined by struct iwl_error_event_table.
380 * The Linux driver can print both logs to the system log when a uCode error
385 * Note: This structure is read from the device with IO accesses,
386 * and the reading already does the endian conversion. As it is
387 * read with u32-sized accesses, any members with a different size
388 * need to be ordered correctly though!

1609 * FILLING THE RATE TABLE
1611 * Given a particular initial rate and mode, as determined by the rate
1612 * scaling algorithm described below, the Linux driver uses the following
1613 * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
1614 * Link Quality command:
1617 * 1) If using High-throughput (HT) (SISO or MIMO) initial rate:
1618 * a) Use this same initial rate for first 3 entries.
1619 * b) Find next lower available rate using same mode (SISO or MIMO),
1620 * use for next 3 entries. If no lower rate available, switch to
1621 * legacy mode (no HT40 channel, no MIMO, no short guard interval).
1622 * c) If using MIMO, set command's mimo_delimiter to number of entries
1623 * using MIMO (3 or 6).
1624 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
1625 * no MIMO, no short guard interval), at the next lower bit rate
1626 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow
1627 * legacy procedure for remaining table entries.
1629 * 2) If using legacy initial rate:
1630 * a) Use the initial rate for only one entry.
1631 * b) For each following entry, reduce the rate to next lower available
1632 * rate, until reaching the lowest available rate.
1633 * c) When reducing rate, also switch antenna selection.
1634 * d) Once lowest available rate is reached, repeat this rate until
1635 * rate table is filled (16 entries), switching antenna each entry.
1638 * ACCUMULATING HISTORY
1640 * The rate scaling algorithm for agn devices, as implemented in Linux driver,
1641 * uses two sets of frame Tx success history: One for the current/active
1642 * modulation mode, and one for a speculative/search mode that is being
1643 * attempted. If the speculative mode turns out to be more effective (i.e.
1644 * actual transfer rate is better), then the driver continues to use the
1645 * speculative mode as the new current active mode.
1647 * Each history set contains, separately for each possible rate, data for a
1648 * sliding window of the 62 most recent tx attempts at that rate. The data
1649 * includes a shifting bitmap of success(1)/failure(0), and sums of successful
1650 * and attempted frames, from which the driver can additionally calculate a
1651 * success ratio (success / attempted) and number of failures
1652 * (attempted - success), and control the size of the window (attempted).
1653 * The driver uses the bit map to remove successes from the success sum, as
1654 * the oldest tx attempts fall out of the window.
1656 * When the agn device makes multiple tx attempts for a given frame, each
1657 * attempt might be at a different rate, and have different modulation
1658 * characteristics (e.g. antenna, fat channel, short guard interval), as set
1659 * up in the rate scaling table in the Link Quality command. The driver must
1660 * determine which rate table entry was used for each tx attempt, to determine
1661 * which rate-specific history to update, and record only those attempts that
1662 * match the modulation characteristics of the history set.
1664 * When using block-ack (aggregation), all frames are transmitted at the same
1665 * rate, since there is no per-attempt acknowledgment from the destination
1666 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in
1667 * rate_n_flags field. After receiving a block-ack, the driver can update
1668 * history for the entire block all at once.
1671 * FINDING BEST STARTING RATE:
1673 * When working with a selected initial modulation mode (see below), the
1674 * driver attempts to find a best initial rate. The initial rate is the
1675 * first entry in the Link Quality command's rate table.
1677 * 1) Calculate actual throughput (success ratio * expected throughput, see
1678 * table below) for current initial rate. Do this only if enough frames
1679 * have been attempted to make the value meaningful: at least 6 failed
1680 * tx attempts, or at least 8 successes. If not enough, don't try rate
1683 * 2) Find available rates adjacent to current initial rate. Available means:
1684 * a) supported by hardware &&
1685 * b) supported by association &&
1686 * c) within any constraints selected by user
1688 * 3) Gather measured throughputs for adjacent rates. These might not have
1689 * enough history to calculate a throughput. That's okay, we might try
1690 * using one of them anyway!
1692 * 4) Try decreasing rate if, for current rate:
1693 * a) success ratio is < 15% ||
1694 * b) lower adjacent rate has better measured throughput ||
1695 * c) higher adjacent rate has worse throughput, and lower is unmeasured
1697 * As a sanity check, if decrease was determined above, leave rate
1699 * a) lower rate unavailable
1700 * b) success ratio at current rate > 85% (very good)
1701 * c) current measured throughput is better than expected throughput
1702 * of lower rate (under perfect 100% tx conditions, see table below)
1704 * 5) Try increasing rate if, for current rate:
1705 * a) success ratio is < 15% ||
1706 * b) both adjacent rates' throughputs are unmeasured (try it!) ||
1707 * b) higher adjacent rate has better measured throughput ||
1708 * c) lower adjacent rate has worse throughput, and higher is unmeasured
1710 * As a sanity check, if increase was determined above, leave rate
1712 * a) success ratio at current rate < 70%. This is not particularly
1713 * good performance; higher rate is sure to have poorer success.
1715 * 6) Re-evaluate the rate after each tx frame. If working with block-
1716 * acknowledge, history and statistics may be calculated for the entire
1717 * block (including prior history that fits within the history windows),
1718 * before re-evaluation.
1720 * FINDING BEST STARTING MODULATION MODE:
1722 * After working with a modulation mode for a "while" (and doing rate scaling),
1723 * the driver searches for a new initial mode in an attempt to improve
1724 * throughput. The "while" is measured by numbers of attempted frames:
1726 * For legacy mode, search for new mode after:
1727 * 480 successful frames, or 160 failed frames
1728 * For high-throughput modes (SISO or MIMO), search for new mode after:
1729 * 4500 successful frames, or 400 failed frames
1731 * Mode switch possibilities are (3 for each mode):
1734 * Change antenna, try SISO (if HT association), try MIMO (if HT association)
1736 * Change antenna, try MIMO, try shortened guard interval (SGI)
1738 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
1740 * When trying a new mode, use the same bit rate as the old/current mode when
1741 * trying antenna switches and shortened guard interval. When switching to
1742 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
1743 * for which the expected throughput (under perfect conditions) is about the
1744 * same or slightly better than the actual measured throughput delivered by
1745 * the old/current mode.
1747 * Actual throughput can be estimated by multiplying the expected throughput
1748 * by the success ratio (successful / attempted tx frames). Frame size is
1749 * not considered in this calculation; it assumes that frame size will average
1750 * out to be fairly consistent over several samples. The following are
1751 * metric values for expected throughput assuming 100% success ratio.
1752 * Only G band has support for CCK rates:
1754 * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60
1756 * G: 7 13 35 58 40 57 72 98 121 154 177 186 186
1757 * A: 0 0 0 0 40 57 72 98 121 154 177 186 186
1758 * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202
1759 * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211
1760 * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251
1761 * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257
1762 * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257
1763 * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264
1764 * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289
1765 * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293
1767 * After the new mode has been tried for a short while (minimum of 6 failed
1768 * frames or 8 successful frames), compare success ratio and actual throughput
1769 * estimate of the new mode with the old. If either is better with the new
1770 * mode, continue to use the new mode.
1772 * Continue comparing modes until all 3 possibilities have been tried.
1773 * If moving from legacy to HT, try all 3 possibilities from the new HT
1774 * mode. After trying all 3, a best mode is found. Continue to use this mode
1775 * for the longer "while" described above (e.g. 480 successful frames for
1776 * legacy), and then repeat the search process.

2269 * REPLY_SCAN_CMD = 0x80 (command)
2271 * The hardware scan command is very powerful; the driver can set it up to
2272 * maintain (relatively) normal network traffic while doing a scan in the
2273 * background. The max_out_time and suspend_time control the ratio of how
2274 * long the device stays on an associated network channel ("service channel")
2275 * vs. how long it's away from the service channel, i.e. tuned to other channels
2278 * max_out_time is the max time off-channel (in usec), and suspend_time
2279 * is how long (in "extended beacon" format) that the scan is "suspended"
2280 * after returning to the service channel. That is, suspend_time is the
2281 * time that we stay on the service channel, doing normal work, between
2282 * scan segments. The driver may set these parameters differently to support
2283 * scanning when associated vs. not associated, and light vs. heavy traffic
2284 * loads when associated.
2286 * After receiving this command, the device's scan engine does the following;
2288 * 1) Sends SCAN_START notification to driver
2289 * 2) Checks to see if it has time to do scan for one channel
2290 * 3) Sends NULL packet, with power-save (PS) bit set to 1,
2291 * to tell AP that we're going off-channel
2292 * 4) Tunes to first channel in scan list, does active or passive scan
2293 * 5) Sends SCAN_RESULT notification to driver
2294 * 6) Checks to see if it has time to do scan on *next* channel in list
2295 * 7) Repeats 4-6 until it no longer has time to scan the next channel
2296 * before max_out_time expires
2297 * 8) Returns to service channel
2298 * 9) Sends NULL packet with PS=0 to tell AP that we're back
2299 * 10) Stays on service channel until suspend_time expires
2300 * 11) Repeats entire process 2-10 until list is complete
2301 * 12) Sends SCAN_COMPLETE notification
2303 * For fast, efficient scans, the scan command also has support for staying on
2304 * a channel for just a short time, if doing active scanning and getting no
2305 * responses to the transmitted probe request. This time is controlled by
2306 * quiet_time, and the number of received packets below which a channel is
2307 * considered "quiet" is controlled by quiet_plcp_threshold.
2309 * For active scanning on channels that have regulatory restrictions against
2310 * blindly transmitting, the scan can listen before transmitting, to make sure
2311 * that there is already legitimate activity on the channel. If enough
2312 * packets are cleanly received on the channel (controlled by good_CRC_th,
2313 * typical value 1), the scan engine starts transmitting probe requests.
2315 * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
2317 * To avoid uCode errors, see timing restrictions described under
2318 * struct iwl_scan_channel.

2794 * 1) Tx power (depends on temperature), described elsewhere
2795 * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
2796 * 3) Receiver sensitivity (to optimize signal detection)
2798 *****************************************************************************/
2801 * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
2803 * This command sets up the Rx signal detector for a sensitivity level that
2804 * is high enough to lock onto all signals within the associated network,
2805 * but low enough to ignore signals that are below a certain threshold, so as
2806 * not to have too many "false alarms". False alarms are signals that the
2807 * Rx DSP tries to lock onto, but then discards after determining that they
2810 * The optimum number of false alarms is between 5 and 50 per 200 TUs
2811 * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
2812 * time listening, not transmitting). Driver must adjust sensitivity so that
2813 * the ratio of actual false alarms to actual Rx time falls within this range.
2815 * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
2816 * received beacon. These provide information to the driver to analyze the
2817 * sensitivity. Don't analyze statistics that come in from scanning, or any
2818 * other non-associated-network source. Pertinent statistics include:
2820 * From "general" statistics (struct statistics_rx_non_phy):
2822 * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
2823 * Measure of energy of desired signal. Used for establishing a level
2824 * below which the device does not detect signals.
2826 * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
2827 * Measure of background noise in silent period after beacon.
2830 * uSecs of actual Rx time during beacon period (varies according to
2831 * how much time was spent transmitting).
2833 * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
2836 * Signal locks abandoned early (before phy-level header).
2839 * Signal locks abandoned late (during phy-level header).
2841 * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
2842 * beacon to beacon, i.e. each value is an accumulation of all errors
2843 * before and including the latest beacon. Values will wrap around to 0
2844 * after counting up to 2^32 - 1. Driver must differentiate vs.
2845 * previous beacon's values to determine # false alarms in the current
2848 * Total number of false alarms = false_alarms + plcp_errs
2850 * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
2851 * (notice that the start points for OFDM are at or close to settings for
2852 * maximum sensitivity):
2855 * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
2856 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
2857 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
2858 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
2860 * If actual rate of OFDM false alarms (+ plcp_errors) is too high
2861 * (greater than 50 for each 204.8 msecs listening), reduce sensitivity
2862 * by *adding* 1 to all 4 of the table entries above, up to the max for
2863 * each entry. Conversely, if false alarm rate is too low (less than 5
2864 * for each 204.8 msecs listening), *subtract* 1 from each entry to
2865 * increase sensitivity.
2867 * For CCK sensitivity, keep track of the following:
2869 * 1). 20-beacon history of maximum background noise, indicated by
2870 * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
2871 * 3 receivers. For any given beacon, the "silence reference" is
2872 * the maximum of last 60 samples (20 beacons * 3 receivers).
2874 * 2). 10-beacon history of strongest signal level, as indicated
2875 * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
2876 * i.e. the strength of the signal through the best receiver at the
2877 * moment. These measurements are "upside down", with lower values
2878 * for stronger signals, so max energy will be *minimum* value.
2880 * Then for any given beacon, the driver must determine the *weakest*
2881 * of the strongest signals; this is the minimum level that needs to be
2882 * successfully detected, when using the best receiver at the moment.
2883 * "Max cck energy" is the maximum (higher value means lower energy!)
2884 * of the last 10 minima. Once this is determined, driver must add
2885 * a little margin by adding "6" to it.
2887 * 3). Number of consecutive beacon periods with too few false alarms.
2888 * Reset this to 0 at the first beacon period that falls within the
2889 * "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
2891 * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
2892 * (notice that the start points for CCK are at maximum sensitivity):
2895 * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
2896 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
2897 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
2899 * If actual rate of CCK false alarms (+ plcp_errors) is too high
2900 * (greater than 50 for each 204.8 msecs listening), method for reducing
2903 * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2906 * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
2907 * sensitivity has been reduced a significant amount; bring it up to
2908 * a moderate 161. Otherwise, *add* 3, up to max 200.
2910 * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
2911 * sensitivity has been reduced only a moderate or small amount;
2912 * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
2913 * down to min 0. Otherwise (if gain has been significantly reduced),
2914 * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
2916 * b) Save a snapshot of the "silence reference".
2918 * If actual rate of CCK false alarms (+ plcp_errors) is too low
2919 * (less than 5 for each 204.8 msecs listening), method for increasing
2920 * sensitivity is used only if:
2922 * 1a) Previous beacon did not have too many false alarms
2923 * 1b) AND difference between previous "silence reference" and current
2924 * "silence reference" (prev - current) is 2 or more,
2925 * OR 2) 100 or more consecutive beacon periods have had rate of
2926 * less than 5 false alarms per 204.8 milliseconds rx time.
2928 * Method for increasing sensitivity:
2930 * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
2933 * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
2936 * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
2938 * If actual rate of CCK false alarms (+ plcp_errors) is within good range
2939 * (between 5 and 50 for each 204.8 msecs listening):
2941 * 1) Save a snapshot of the silence reference.
2943 * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
2944 * give some extra margin to energy threshold by *subtracting* 8
2945 * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
2947 * For all cases (too few, too many, good range), make sure that the CCK
2948 * detection threshold (energy) is below the energy level for robust
2949 * detection over the past 10 beacon periods, the "Max cck energy".
2950 * Lower values mean higher energy; this means making sure that the value
2951 * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

3068 * (A and B are the only 2 Tx chains!).
3073 * Driver should balance the 3 receivers (but just the ones that are connected
3074 * to antennas, see above) for gain, by comparing the average signal levels
3075 * detected during the silence after each beacon (background noise).
3076 * Accumulate (add) the following values over 20 beacons, one accumulator for
3077 * each of the chains a/b/c, from struct statistics_rx_non_phy:
3079 * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
3081 * Find the weakest background noise level from among a/b/c. This Rx chain
