|
* __le32 event_id; range 0 - 1500 |
|
* __le32 timestamp; low 32 bits of TSF (of network, if associated) |

* __le32 data; event_id-specific data value |

* |

* Entries without timestamps contain only event_id and data. |

* 2) error_event_table_ptr indicates base of the error log. This contains |
|
* information about any uCode error that occurs. For agn, the format |
|
* of the error log is defined by struct iwl_error_event_table. |

|
* SCD registers and Tx/Rx Queues). When the device's Tx scheduler and uCode |

* are preparing to transmit, the device pulls the Tx command over the PCI |
|
* bus via one of the device's Tx DMA channels, to fill an internal FIFO |
|
* from which data will be transmitted. |
|
* |
|
* uCode handles all timing and protocol related to control frames |
|
* (RTS/CTS/ACK), based on flags in the Tx command. uCode and Tx scheduler |
|
* handle reception of block-acks; uCode updates the host driver via |
|
* REPLY_COMPRESSED_BA. |
|
* |
|
* uCode handles retrying Tx when an ACK is expected but not received. |
|
* This includes trying lower data rates than the one requested in the Tx |
|
* command, as set up by the REPLY_TX_LINK_QUALITY_CMD (agn). |
|
* |
|
* Driver sets up transmit power for various rates via REPLY_TX_PWR_TABLE_CMD. |

|
* For agn devices |
|
* |
|
* Each station in the agn device's internal station table has its own table |
|
* of 16 |
|
* Tx rates and modulation modes (e.g. legacy/SISO/MIMO) for retrying Tx when |
|
* an ACK is not received. This command replaces the entire table for |

* Use REPLY_ADD_STA. |
|
* |
|
* The rate scaling procedures described below work well. Of course, other |
|
* procedures are possible, and may work better for particular environments. |
|
* |
|
* |
|
* 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 |
|
* by the success ratio (successful / attempted tx frames). Frame size is |
|
* not considered in this calculation; it assumes that frame size will average |
|
* out to be fairly consistent over several samples. The following are |
|
* metric values for expected throughput assuming 100% success ratio. |
|
* Only G band has support for CCK rates: |
|
* |
|
* RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 |
|
* |
|
* G: 7 13 35 58 40 57 72 98 121 154 177 186 186 |
|
* A: 0 0 0 0 40 57 72 98 121 154 177 186 186 |
|
* SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 |
|
* SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 |
|
* MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 |
|
* SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 |
|
* SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 |
|
* SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 |
|
* MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 |
|
* SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 |
|
* |
|
* After the new mode has been tried for a short while (minimum of 6 failed |
|
* frames or 8 successful frames), compare success ratio and actual throughput |
|
* estimate of the new mode with the old. If either is better with the new |
|
* mode, continue to use the new mode. |
|
* |
|
* Continue comparing modes until all 3 possibilities have been tried. |
|
* If moving from legacy to HT, try all 3 possibilities from the new HT |
|
* mode. After trying all 3, a best mode is found. Continue to use this mode |
|
* for the longer "while" described above (e.g. 480 successful frames for |
|
* legacy), and then repeat the search process. |

/* |
|
* 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 |
