|
|
* FILLING THE RATE TABLE
|
|
*
|
|
* Given a particular initial rate and mode, as determined by the rate
|
|
* scaling algorithm described below, the Linux driver uses the following
|
|
* formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the
|
|
* Link Quality command:
|
|
*
|
|
*
|
|
* 1) If using High-throughput (HT) (SISO or MIMO) initial rate:
|
|
* a) Use this same initial rate for first 3 entries.
|
|
* b) Find next lower available rate using same mode (SISO or MIMO),
|
|
* use for next 3 entries. If no lower rate available, switch to
|
|
* legacy mode (no HT40 channel, no MIMO, no short guard interval).
|
|
* c) If using MIMO, set command's mimo_delimiter to number of entries
|
|
* using MIMO (3 or 6).
|
|
* d) After trying 2 HT rates, switch to legacy mode (no HT40 channel,
|
|
* no MIMO, no short guard interval), at the next lower bit rate
|
|
* (e.g. if second HT bit rate was 54, try 48 legacy), and follow
|
|
* legacy procedure for remaining table entries.
|
|
*
|
|
* 2) If using legacy initial rate:
|
|
* a) Use the initial rate for only one entry.
|
|
* b) For each following entry, reduce the rate to next lower available
|
|
* rate, until reaching the lowest available rate.
|
|
* c) When reducing rate, also switch antenna selection.
|
|
* d) Once lowest available rate is reached, repeat this rate until
|
|
* rate table is filled (16 entries), switching antenna each entry.
|
|
*
|
|
*
|
|
* ACCUMULATING HISTORY
|
|
*
|
|
* The rate scaling algorithm for agn devices, as implemented in Linux driver,
|
|
* uses two sets of frame Tx success history: One for the current/active
|
|
* modulation mode, and one for a speculative/search mode that is being
|
|
* attempted. If the speculative mode turns out to be more effective (i.e.
|
|
* actual transfer rate is better), then the driver continues to use the
|
|
* speculative mode as the new current active mode.
|
|
*
|
|
* Each history set contains, separately for each possible rate, data for a
|
|
* sliding window of the 62 most recent tx attempts at that rate. The data
|
|
* includes a shifting bitmap of success(1)/failure(0), and sums of successful
|
|
* and attempted frames, from which the driver can additionally calculate a
|
|
* success ratio (success / attempted) and number of failures
|
|
* (attempted - success), and control the size of the window (attempted).
|
|
* The driver uses the bit map to remove successes from the success sum, as
|
|
* the oldest tx attempts fall out of the window.
|
|
*
|
|
* When the agn device makes multiple tx attempts for a given frame, each
|
|
* attempt might be at a different rate, and have different modulation
|
|
* characteristics (e.g. antenna, fat channel, short guard interval), as set
|
|
* up in the rate scaling table in the Link Quality command. The driver must
|
|
* determine which rate table entry was used for each tx attempt, to determine
|
|
* which rate-specific history to update, and record only those attempts that
|
|
* match the modulation characteristics of the history set.
|
|
*
|
|
* When using block-ack (aggregation), all frames are transmitted at the same
|
|
* rate, since there is no per-attempt acknowledgment from the destination
|
|
* station. The Tx response struct iwl_tx_resp indicates the Tx rate in
|
|
* rate_n_flags field. After receiving a block-ack, the driver can update
|
|
* history for the entire block all at once.
|
|
*
|
|
*
|
|
* FINDING BEST STARTING RATE:
|
|
*
|
|
* When working with a selected initial modulation mode (see below), the
|
|
* driver attempts to find a best initial rate. The initial rate is the
|
|
* first entry in the Link Quality command's rate table.
|
|
*
|
|
* 1) Calculate actual throughput (success ratio * expected throughput, see
|
|
* table below) for current initial rate. Do this only if enough frames
|
|
* have been attempted to make the value meaningful: at least 6 failed
|
|
* tx attempts, or at least 8 successes. If not enough, don't try rate
|
|
* scaling yet.
|
|
*
|
|
* 2) Find available rates adjacent to current initial rate. Available means:
|
|
* a) supported by hardware &&
|
|
* b) supported by association &&
|
|
* c) within any constraints selected by user
|
|
*
|
|
* 3) Gather measured throughputs for adjacent rates. These might not have
|
|
* enough history to calculate a throughput. That's okay, we might try
|
|
* using one of them anyway!
|
|
*
|
|
* 4) Try decreasing rate if, for current rate:
|
|
* a) success ratio is < 15% ||
|
|
* b) lower adjacent rate has better measured throughput ||
|
|
* c) higher adjacent rate has worse throughput, and lower is unmeasured
|
|
*
|
|
* As a sanity check, if decrease was determined above, leave rate
|
|
* unchanged if:
|
|
* a) lower rate unavailable
|
|
* b) success ratio at current rate > 85% (very good)
|
|
* c) current measured throughput is better than expected throughput
|
|
* of lower rate (under perfect 100% tx conditions, see table below)
|
|
*
|
|
* 5) Try increasing rate if, for current rate:
|
|
* a) success ratio is < 15% ||
|
|
* b) both adjacent rates' throughputs are unmeasured (try it!) ||
|
|
* b) higher adjacent rate has better measured throughput ||
|
|
* c) lower adjacent rate has worse throughput, and higher is unmeasured
|
|
*
|
|
* As a sanity check, if increase was determined above, leave rate
|
|
* unchanged if:
|
|
* a) success ratio at current rate < 70%. This is not particularly
|
|
* good performance; higher rate is sure to have poorer success.
|
|
*
|
|
* 6) Re-evaluate the rate after each tx frame. If working with block-
|
|
* acknowledge, history and statistics may be calculated for the entire
|
|
* block (including prior history that fits within the history windows),
|
|
* before re-evaluation.
|
|
*
|
|
* FINDING BEST STARTING MODULATION MODE:
|
|
*
|
|
* After working with a modulation mode for a "while" (and doing rate scaling),
|
|
* the driver searches for a new initial mode in an attempt to improve
|
|
* throughput. The "while" is measured by numbers of attempted frames:
|
|
*
|
|
* For legacy mode, search for new mode after:
|
|
* 480 successful frames, or 160 failed frames
|
|
* For high-throughput modes (SISO or MIMO), search for new mode after:
|
|
* 4500 successful frames, or 400 failed frames
|
|
*
|
|
* Mode switch possibilities are (3 for each mode):
|
|
*
|
|
* For legacy:
|
|
* Change antenna, try SISO (if HT association), try MIMO (if HT association)
|
|
* For SISO:
|
|
* Change antenna, try MIMO, try shortened guard interval (SGI)
|
|
* For MIMO:
|
|
* Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI)
|
|
*
|
|
* When trying a new mode, use the same bit rate as the old/current mode when
|
|
* trying antenna switches and shortened guard interval. When switching to
|
|
* SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate
|
|
* for which the expected throughput (under perfect conditions) is about the
|
|
* same or slightly better than the actual measured throughput delivered by
|
|
* the old/current mode.
|
|
*
|
|
* Actual throughput can be estimated by multiplying the expected throughput
|

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

/**
|
|
* SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
|
|
*
|
|
* This command sets up the Rx signal detector for a sensitivity level that
|
|
* is high enough to lock onto all signals within the associated network,
|
|
* but low enough to ignore signals that are below a certain threshold, so as
|
|
* not to have too many "false alarms". False alarms are signals that the
|
|
* Rx DSP tries to lock onto, but then discards after determining that they
|
|
* are noise.
|
|
*
|
|
* The optimum number of false alarms is between 5 and 50 per 200 TUs
|
|
* (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
|
|
* time listening, not transmitting). Driver must adjust sensitivity so that
|
|
* the ratio of actual false alarms to actual Rx time falls within this range.
|
|
*
|
|
* While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
|
|
* received beacon. These provide information to the driver to analyze the
|
|
* sensitivity. Don't analyze statistics that come in from scanning, or any
|
|
* other non-associated-network source. Pertinent statistics include:
|
|
*
|
|
* From "general" statistics (struct statistics_rx_non_phy):
|
|
*
|
|
* (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
|
|
* Measure of energy of desired signal. Used for establishing a level
|
|
* below which the device does not detect signals.
|
|
*
|
|
* (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
|
|
* Measure of background noise in silent period after beacon.
|
|
*
|
|
* channel_load
|
|
* uSecs of actual Rx time during beacon period (varies according to
|
|
* how much time was spent transmitting).
|
|
*
|
|
* From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
|
|
*
|
|
* false_alarm_cnt
|
|
* Signal locks abandoned early (before phy-level header).
|
|
*
|
|
* plcp_err
|
|
* Signal locks abandoned late (during phy-level header).
|
|
*
|
|
* NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
|
|
* beacon to beacon, i.e. each value is an accumulation of all errors
|
|
* before and including the latest beacon. Values will wrap around to 0
|
|
* after counting up to 2^32 - 1. Driver must differentiate vs.
|
|
* previous beacon's values to determine # false alarms in the current
|
|
* beacon period.
|
|
*
|
|
* Total number of false alarms = false_alarms + plcp_errs
|
|
*
|
|
* For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
|
|
* (notice that the start points for OFDM are at or close to settings for
|
|
* maximum sensitivity):
|
|
*
|
|
* START / MIN / MAX
|
|
* HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
|
|
* HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
|
|
* HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
|
|
* HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
|
|
*
|
|
* If actual rate of OFDM false alarms (+ plcp_errors) is too high
|
|
* (greater than 50 for each 204.8 msecs listening), reduce sensitivity
|
|
* by *adding* 1 to all 4 of the table entries above, up to the max for
|
|
* each entry. Conversely, if false alarm rate is too low (less than 5
|
|
* for each 204.8 msecs listening), *subtract* 1 from each entry to
|
|
* increase sensitivity.
|
|
*
|
|
* For CCK sensitivity, keep track of the following:
|
|
*
|
|
* 1). 20-beacon history of maximum background noise, indicated by
|
|
* (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
|
|
* 3 receivers. For any given beacon, the "silence reference" is
|
|
* the maximum of last 60 samples (20 beacons * 3 receivers).
|
|
*
|
|
* 2). 10-beacon history of strongest signal level, as indicated
|
|
* by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
|
|
* i.e. the strength of the signal through the best receiver at the
|
|
* moment. These measurements are "upside down", with lower values
|
|
* for stronger signals, so max energy will be *minimum* value.
|
|
*
|
|
* Then for any given beacon, the driver must determine the *weakest*
|
|
* of the strongest signals; this is the minimum level that needs to be
|
|
* successfully detected, when using the best receiver at the moment.
|
|
* "Max cck energy" is the maximum (higher value means lower energy!)
|
|
* of the last 10 minima. Once this is determined, driver must add
|
|
* a little margin by adding "6" to it.
|
|
*
|
|
* 3). Number of consecutive beacon periods with too few false alarms.
|
|
* Reset this to 0 at the first beacon period that falls within the
|
|
* "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
|
|
*
|
|
* Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
|
|
* (notice that the start points for CCK are at maximum sensitivity):
|
|
*
|
|
* START / MIN / MAX
|
|
* HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
|
|
* HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
|
|
* HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
|
|
*
|
|
* If actual rate of CCK false alarms (+ plcp_errors) is too high
|
|
* (greater than 50 for each 204.8 msecs listening), method for reducing
|
|
* sensitivity is:
|
|
*
|
|
* 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
|
|
* up to max 400.
|
|
*
|
|
* 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
|
|
* sensitivity has been reduced a significant amount; bring it up to
|
|
* a moderate 161. Otherwise, *add* 3, up to max 200.
|
|
*
|
|
* 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
|
|
* sensitivity has been reduced only a moderate or small amount;
|
|
* *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
|
|
* down to min 0. Otherwise (if gain has been significantly reduced),
|
|
* don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
|
|
*
|
|
* b) Save a snapshot of the "silence reference".
|
|
*
|
|
* If actual rate of CCK false alarms (+ plcp_errors) is too low
|
|
* (less than 5 for each 204.8 msecs listening), method for increasing
|
|
* sensitivity is used only if:
|
|
*
|
|
* 1a) Previous beacon did not have too many false alarms
|
|
* 1b) AND difference between previous "silence reference" and current
|
|
* "silence reference" (prev - current) is 2 or more,
|
|
* OR 2) 100 or more consecutive beacon periods have had rate of
|
|
* less than 5 false alarms per 204.8 milliseconds rx time.
|
|
*
|
|
* Method for increasing sensitivity:
|
|
*
|
|
* 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
|
|
* down to min 125.
|
|
*
|
|
* 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
|
|
* down to min 200.
|
|
*
|
|
* 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
|
|
*
|
|
* If actual rate of CCK false alarms (+ plcp_errors) is within good range
|
|
* (between 5 and 50 for each 204.8 msecs listening):
|
|
*
|
|
* 1) Save a snapshot of the silence reference.
|
|
*
|
|
* 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
|
|
* give some extra margin to energy threshold by *subtracting* 8
|
|
* from value in HD_MIN_ENERGY_CCK_DET_INDEX.
|
|
*
|
|
* For all cases (too few, too many, good range), make sure that the CCK
|
|
* detection threshold (energy) is below the energy level for robust
|
|
* detection over the past 10 beacon periods, the "Max cck energy".
|
|
* Lower values mean higher energy; this means making sure that the value
|
|
* in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

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