221 u8 cmd; /* Command ID: REPLY_RXON, etc. */

224 * The driver sets up the sequence number to values of its choosing.
225 * uCode does not use this value, but passes it back to the driver
226 * when sending the response to each driver-originated command, so
227 * the driver can match the response to the command. Since the values
228 * don't get used by uCode, the driver may set up an arbitrary format.
230 * There is one exception: uCode sets bit 15 when it originates
231 * the response/notification, i.e. when the response/notification
232 * is not a direct response to a command sent by the driver. For
233 * example, uCode issues REPLY_3945_RX when it sends a received frame
234 * to the driver; it is not a direct response to any driver command.
236 * The Linux driver uses the following format:
238 * 0:7 tfd index - position within TX queue
241 * 14 huge - driver sets this to indicate command is in the
242 * 'huge' storage at the end of the command buffers

259 * linear value that multiplies the output of the digital signal processor,
260 * before being sent to the analog radio.
261 * 2) Radio gain. This sets the analog gain of the radio Tx path.

2187 * FILLING THE RATE TABLE
2189 * Given a particular initial rate and mode, as determined by the rate
2190 * scaling algorithm described below, the Linux driver uses the following
2191 * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
2192 * Link Quality command:
2195 * 1) If using High-throughput (HT) (SISO or MIMO) initial rate:
2196 * a) Use this same initial rate for first 3 entries.
2197 * b) Find next lower available rate using same mode (SISO or MIMO),
2198 * use for next 3 entries. If no lower rate available, switch to
2199 * legacy mode (no HT40 channel, no MIMO, no short guard interval).
2200 * c) If using MIMO, set command's mimo_delimiter to number of entries
2201 * using MIMO (3 or 6).
2202 * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
2203 * no MIMO, no short guard interval), at the next lower bit rate
2204 * (e.g. if second HT bit rate was 54, try 48 legacy), and follow
2205 * legacy procedure for remaining table entries.
2207 * 2) If using legacy initial rate:
2208 * a) Use the initial rate for only one entry.
2209 * b) For each following entry, reduce the rate to next lower available
2210 * rate, until reaching the lowest available rate.
2211 * c) When reducing rate, also switch antenna selection.
2212 * d) Once lowest available rate is reached, repeat this rate until
2213 * rate table is filled (16 entries), switching antenna each entry.
2216 * ACCUMULATING HISTORY
2218 * The rate scaling algorithm for agn devices, as implemented in Linux driver,
2219 * uses two sets of frame Tx success history: One for the current/active
2220 * modulation mode, and one for a speculative/search mode that is being
2221 * attempted. If the speculative mode turns out to be more effective (i.e.
2222 * actual transfer rate is better), then the driver continues to use the
2223 * speculative mode as the new current active mode.
2225 * Each history set contains, separately for each possible rate, data for a
2226 * sliding window of the 62 most recent tx attempts at that rate. The data
2227 * includes a shifting bitmap of success(1)/failure(0), and sums of successful
2228 * and attempted frames, from which the driver can additionally calculate a
2229 * success ratio (success / attempted) and number of failures
2230 * (attempted - success), and control the size of the window (attempted).
2231 * The driver uses the bit map to remove successes from the success sum, as
2232 * the oldest tx attempts fall out of the window.
2234 * When the agn device makes multiple tx attempts for a given frame, each
2235 * attempt might be at a different rate, and have different modulation
2236 * characteristics (e.g. antenna, fat channel, short guard interval), as set
2237 * up in the rate scaling table in the Link Quality command. The driver must
2238 * determine which rate table entry was used for each tx attempt, to determine
2239 * which rate-specific history to update, and record only those attempts that
2240 * match the modulation characteristics of the history set.
2242 * When using block-ack (aggregation), all frames are transmitted at the same
2243 * rate, since there is no per-attempt acknowledgment from the destination
2244 * station. The Tx response struct iwl_tx_resp indicates the Tx rate in
2245 * rate_n_flags field. After receiving a block-ack, the driver can update
2246 * history for the entire block all at once.
2249 * FINDING BEST STARTING RATE:
2251 * When working with a selected initial modulation mode (see below), the
2252 * driver attempts to find a best initial rate. The initial rate is the
2253 * first entry in the Link Quality command's rate table.
2255 * 1) Calculate actual throughput (success ratio * expected throughput, see
2256 * table below) for current initial rate. Do this only if enough frames
2257 * have been attempted to make the value meaningful: at least 6 failed
2258 * tx attempts, or at least 8 successes. If not enough, don't try rate
2261 * 2) Find available rates adjacent to current initial rate. Available means:
2262 * a) supported by hardware &&
2263 * b) supported by association &&
2264 * c) within any constraints selected by user
2266 * 3) Gather measured throughputs for adjacent rates. These might not have
2267 * enough history to calculate a throughput. That's okay, we might try
2268 * using one of them anyway!
2270 * 4) Try decreasing rate if, for current rate:
2271 * a) success ratio is < 15% ||
2272 * b) lower adjacent rate has better measured throughput ||
2273 * c) higher adjacent rate has worse throughput, and lower is unmeasured
2275 * As a sanity check, if decrease was determined above, leave rate
2277 * a) lower rate unavailable
2278 * b) success ratio at current rate > 85% (very good)
2279 * c) current measured throughput is better than expected throughput
2280 * of lower rate (under perfect 100% tx conditions, see table below)
2282 * 5) Try increasing rate if, for current rate:
2283 * a) success ratio is < 15% ||
2284 * b) both adjacent rates' throughputs are unmeasured (try it!) ||
2285 * b) higher adjacent rate has better measured throughput ||
2286 * c) lower adjacent rate has worse throughput, and higher is unmeasured
2288 * As a sanity check, if increase was determined above, leave rate
2290 * a) success ratio at current rate < 70%. This is not particularly
2291 * good performance; higher rate is sure to have poorer success.
2293 * 6) Re-evaluate the rate after each tx frame. If working with block-
2294 * acknowledge, history and statistics may be calculated for the entire
2295 * block (including prior history that fits within the history windows),
2296 * before re-evaluation.
2298 * FINDING BEST STARTING MODULATION MODE:
2300 * After working with a modulation mode for a "while" (and doing rate scaling),
2301 * the driver searches for a new initial mode in an attempt to improve
2302 * throughput. The "while" is measured by numbers of attempted frames:
2304 * For legacy mode, search for new mode after:
2305 * 480 successful frames, or 160 failed frames
2306 * For high-throughput modes (SISO or MIMO), search for new mode after:
2307 * 4500 successful frames, or 400 failed frames
2309 * Mode switch possibilities are (3 for each mode):
2312 * Change antenna, try SISO (if HT association), try MIMO (if HT association)
2314 * Change antenna, try MIMO, try shortened guard interval (SGI)
2316 * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
2318 * When trying a new mode, use the same bit rate as the old/current mode when
2319 * trying antenna switches and shortened guard interval. When switching to
2320 * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
2321 * for which the expected throughput (under perfect conditions) is about the
2322 * same or slightly better than the actual measured throughput delivered by
2323 * the old/current mode.
2325 * Actual throughput can be estimated by multiplying the expected throughput
2326 * by the success ratio (successful / attempted tx frames). Frame size is
2327 * not considered in this calculation; it assumes that frame size will average
2328 * out to be fairly consistent over several samples. The following are
2329 * metric values for expected throughput assuming 100% success ratio.
2330 * Only G band has support for CCK rates:
2332 * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60
2334 * G: 7 13 35 58 40 57 72 98 121 154 177 186 186

2339 * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257
2340 * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257

2343 * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293
2345 * After the new mode has been tried for a short while (minimum of 6 failed
2346 * frames or 8 successful frames), compare success ratio and actual throughput
2347 * estimate of the new mode with the old. If either is better with the new
2348 * mode, continue to use the new mode.
2350 * Continue comparing modes until all 3 possibilities have been tried.
2351 * If moving from legacy to HT, try all 3 possibilities from the new HT
2352 * mode. After trying all 3, a best mode is found. Continue to use this mode
2353 * for the longer "while" described above (e.g. 480 successful frames for
2354 * legacy), and then repeat the search process.

2858 * The hardware scan command is very powerful; the driver can set it up to
2859 * maintain (relatively) normal network traffic while doing a scan in the
2860 * background. The max_out_time and suspend_time control the ratio of how
2861 * long the device stays on an associated network channel ("service channel")
2862 * vs. how long it's away from the service channel, i.e. tuned to other channels
2865 * max_out_time is the max time off-channel (in usec), and suspend_time
2866 * is how long (in "extended beacon" format) that the scan is "suspended"
2867 * after returning to the service channel. That is, suspend_time is the
2868 * time that we stay on the service channel, doing normal work, between
2869 * scan segments. The driver may set these parameters differently to support
2870 * scanning when associated vs. not associated, and light vs. heavy traffic
2871 * loads when associated.
2873 * After receiving this command, the device's scan engine does the following;
2875 * 1) Sends SCAN_START notification to driver
2876 * 2) Checks to see if it has time to do scan for one channel
2877 * 3) Sends NULL packet, with power-save (PS) bit set to 1,
2878 * to tell AP that we're going off-channel
2879 * 4) Tunes to first channel in scan list, does active or passive scan
2880 * 5) Sends SCAN_RESULT notification to driver
2881 * 6) Checks to see if it has time to do scan on *next* channel in list
2882 * 7) Repeats 4-6 until it no longer has time to scan the next channel
2883 * before max_out_time expires
2884 * 8) Returns to service channel
2885 * 9) Sends NULL packet with PS=0 to tell AP that we're back
2886 * 10) Stays on service channel until suspend_time expires
2887 * 11) Repeats entire process 2-10 until list is complete
2888 * 12) Sends SCAN_COMPLETE notification
2890 * For fast, efficient scans, the scan command also has support for staying on
2891 * a channel for just a short time, if doing active scanning and getting no
2892 * responses to the transmitted probe request. This time is controlled by
2893 * quiet_time, and the number of received packets below which a channel is
2894 * considered "quiet" is controlled by quiet_plcp_threshold.
2896 * For active scanning on channels that have regulatory restrictions against
2897 * blindly transmitting, the scan can listen before transmitting, to make sure
2898 * that there is already legitimate activity on the channel. If enough
2899 * packets are cleanly received on the channel (controlled by good_CRC_th,
2900 * typical value 1), the scan engine starts transmitting probe requests.
2902 * Driver must use separate scan commands for 2.4 vs. 5 GHz bands.
2904 * To avoid uCode errors, see timing restrictions described under
2905 * struct iwl_scan_channel.

3507 * 1) Tx power (depends on temperature), described elsewhere
3508 * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
3509 * 3) Receiver sensitivity (to optimize signal detection)
3511 *****************************************************************************/
3514 * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
3516 * This command sets up the Rx signal detector for a sensitivity level that
3517 * is high enough to lock onto all signals within the associated network,
3518 * but low enough to ignore signals that are below a certain threshold, so as
3519 * not to have too many "false alarms". False alarms are signals that the
3520 * Rx DSP tries to lock onto, but then discards after determining that they
3523 * The optimum number of false alarms is between 5 and 50 per 200 TUs
3524 * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
3525 * time listening, not transmitting). Driver must adjust sensitivity so that
3526 * the ratio of actual false alarms to actual Rx time falls within this range.
3528 * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
3529 * received beacon. These provide information to the driver to analyze the
3530 * sensitivity. Don't analyze statistics that come in from scanning, or any
3531 * other non-associated-network source. Pertinent statistics include:
3533 * From "general" statistics (struct statistics_rx_non_phy):
3535 * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
3536 * Measure of energy of desired signal. Used for establishing a level
3537 * below which the device does not detect signals.
3539 * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
3540 * Measure of background noise in silent period after beacon.
3543 * uSecs of actual Rx time during beacon period (varies according to
3544 * how much time was spent transmitting).
3546 * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
3549 * Signal locks abandoned early (before phy-level header).
3552 * Signal locks abandoned late (during phy-level header).
3554 * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
3555 * beacon to beacon, i.e. each value is an accumulation of all errors
3556 * before and including the latest beacon. Values will wrap around to 0
3557 * after counting up to 2^32 - 1. Driver must differentiate vs.
3558 * previous beacon's values to determine # false alarms in the current
3561 * Total number of false alarms = false_alarms + plcp_errs
3563 * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
3564 * (notice that the start points for OFDM are at or close to settings for
3565 * maximum sensitivity):
3568 * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
3569 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
3570 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
3571 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
3573 * If actual rate of OFDM false alarms (+ plcp_errors) is too high
3574 * (greater than 50 for each 204.8 msecs listening), reduce sensitivity
3575 * by *adding* 1 to all 4 of the table entries above, up to the max for
3576 * each entry. Conversely, if false alarm rate is too low (less than 5
3577 * for each 204.8 msecs listening), *subtract* 1 from each entry to
3578 * increase sensitivity.
3580 * For CCK sensitivity, keep track of the following:
3582 * 1). 20-beacon history of maximum background noise, indicated by
3583 * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
3584 * 3 receivers. For any given beacon, the "silence reference" is
3585 * the maximum of last 60 samples (20 beacons * 3 receivers).
3587 * 2). 10-beacon history of strongest signal level, as indicated
3588 * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
3589 * i.e. the strength of the signal through the best receiver at the
3590 * moment. These measurements are "upside down", with lower values
3591 * for stronger signals, so max energy will be *minimum* value.
3593 * Then for any given beacon, the driver must determine the *weakest*
3594 * of the strongest signals; this is the minimum level that needs to be
3595 * successfully detected, when using the best receiver at the moment.
3596 * "Max cck energy" is the maximum (higher value means lower energy!)
3597 * of the last 10 minima. Once this is determined, driver must add
3598 * a little margin by adding "6" to it.
3600 * 3). Number of consecutive beacon periods with too few false alarms.
3601 * Reset this to 0 at the first beacon period that falls within the
3602 * "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
3604 * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
3605 * (notice that the start points for CCK are at maximum sensitivity):
3608 * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
3609 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
3610 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
3612 * If actual rate of CCK false alarms (+ plcp_errors) is too high
3613 * (greater than 50 for each 204.8 msecs listening), method for reducing
3616 * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
3619 * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,

3661 * detection threshold (energy) is below the energy level for robust
3662 * detection over the past 10 beacon periods, the "Max cck energy".

3769 * (A and B are the only 2 Tx chains!).
3774 * Driver should balance the 3 receivers (but just the ones that are connected
3775 * to antennas, see above) for gain, by comparing the average signal levels
3776 * detected during the silence after each beacon (background noise).
3777 * Accumulate (add) the following values over 20 beacons, one accumulator for
3778 * each of the chains a/b/c, from struct statistics_rx_non_phy:
3780 * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB)
3782 * Find the weakest background noise level from among a/b/c. This Rx chain
