16 | ---help--- | ||
17 | This option will enable debug tracing output for the iwlwifilegacy | ||
18 | drivers. | ||
19 | |||
20 | This will result in the kernel module being ~100k larger. You can | ||
21 | control which debug output is sent to the kernel log by setting the | ||
22 | value in | ||
23 | |||
24 | /sys/class/net/wlan0/device/debug_level | ||
25 | |||
26 | This entry will only exist if this option is enabled. | ||
27 | |||
28 | To set a value, simply echo an 8-byte hex value to the same file: | ||
29 | |||
30 | % echo 0x43fff > /sys/class/net/wlan0/device/debug_level | ||
31 | |||
32 | You can find the list of debug mask values in: | ||
33 | drivers/net/wireless/iwlwifilegacy/iwl-debug.h | ||
34 | |||
35 | If this is your first time using this driver, you should say Y here | ||
36 | as the debug information can assist others in helping you resolve | ||

43 | Enable creation of debugfs files for the iwlwifilegacy drivers. This | ||

51 | help | ||
52 | Say Y here to trace all commands, including TX frames and IO | ||
53 | accesses, sent to the device. If you say yes, iwlwifilegacy will | ||
54 | register with the ftrace framework for event tracing and dump | ||
55 | all this information to the ringbuffer, you may need to | ||
56 | increase the ringbuffer size. See the ftrace documentation | ||
57 | for more information. | ||
58 | |||
59 | When tracing is not enabled, this option still has some | ||
60 | (though rather small) overhead. | ||
61 | |||
62 | If unsure, say Y so we can help you better when problems | ||
63 | occur. | ||

57 | * Regular (not A-MPDU) frames are put into hardware queues corresponding | ||
58 | * to the FIFOs, see comments in iwl-prph.h. Aggregated frames get their | ||
59 | * own queue per aggregation session (RA/TID combination), such queues are | ||
60 | * set up to map into FIFOs too, for which we need an AC->FIFO mapping. In | ||
61 | * order to map frames to the right queue, we also need an AC->hw queue | ||
62 | * mapping. This is implemented here. | ||
63 | * | ||
64 | * Due to the way hw queues are set up (by the hw specific modules like | ||
65 | * iwl-4965.c), the AC->hw queue mapping is the identity | ||

1912 | * FILLING THE RATE TABLE | ||
1913 | * | ||
1914 | * Given a particular initial rate and mode, as determined by the rate | ||
1915 | * scaling algorithm described below, the Linux driver uses the following | ||
1916 | * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the | ||
1917 | * Link Quality command: | ||
1918 | * | ||
1919 | * | ||
1920 | * 1) If using High-throughput (HT) (SISO or MIMO) initial rate: | ||
1921 | * a) Use this same initial rate for first 3 entries. | ||
1922 | * b) Find next lower available rate using same mode (SISO or MIMO), | ||
1923 | * use for next 3 entries. If no lower rate available, switch to | ||
1924 | * legacy mode (no HT40 channel, no MIMO, no short guard interval). | ||
1925 | * c) If using MIMO, set command's mimo_delimiter to number of entries | ||
1926 | * using MIMO (3 or 6). | ||
1927 | * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, | ||
1928 | * no MIMO, no short guard interval), at the next lower bit rate | ||
1929 | * (e.g. if second HT bit rate was 54, try 48 legacy), and follow | ||
1930 | * legacy procedure for remaining table entries. | ||
1931 | * | ||
1932 | * 2) If using legacy initial rate: | ||
1933 | * a) Use the initial rate for only one entry. | ||
1934 | * b) For each following entry, reduce the rate to next lower available | ||
1935 | * rate, until reaching the lowest available rate. | ||
1936 | * c) When reducing rate, also switch antenna selection. | ||
1937 | * d) Once lowest available rate is reached, repeat this rate until | ||
1938 | * rate table is filled (16 entries), switching antenna each entry. | ||
1939 | * | ||
1940 | * | ||
1941 | * ACCUMULATING HISTORY | ||
1942 | * | ||
1943 | * The rate scaling algorithm for 4965 devices, as implemented in Linux driver, | ||
1944 | * uses two sets of frame Tx success history: One for the current/active | ||
1945 | * modulation mode, and one for a speculative/search mode that is being | ||
1946 | * attempted. If the speculative mode turns out to be more effective (i.e. | ||
1947 | * actual transfer rate is better), then the driver continues to use the | ||
1948 | * speculative mode as the new current active mode. | ||
1949 | * | ||
1950 | * Each history set contains, separately for each possible rate, data for a | ||
1951 | * sliding window of the 62 most recent tx attempts at that rate. The data | ||
1952 | * includes a shifting bitmap of success(1)/failure(0), and sums of successful | ||
1953 | * and attempted frames, from which the driver can additionally calculate a | ||
1954 | * success ratio (success / attempted) and number of failures | ||
1955 | * (attempted - success), and control the size of the window (attempted). | ||
1956 | * The driver uses the bit map to remove successes from the success sum, as | ||
1957 | * the oldest tx attempts fall out of the window. | ||
1958 | * | ||
1959 | * When the 4965 device makes multiple tx attempts for a given frame, each | ||
1960 | * attempt might be at a different rate, and have different modulation | ||
1961 | * characteristics (e.g. antenna, fat channel, short guard interval), as set | ||
1962 | * up in the rate scaling table in the Link Quality command. The driver must | ||
1963 | * determine which rate table entry was used for each tx attempt, to determine | ||
1964 | * which rate-specific history to update, and record only those attempts that | ||
1965 | * match the modulation characteristics of the history set. | ||
1966 | * | ||
1967 | * When using block-ack (aggregation), all frames are transmitted at the same | ||
1968 | * rate, since there is no per-attempt acknowledgment from the destination | ||
1969 | * station. The Tx response struct iwl_tx_resp indicates the Tx rate in | ||
1970 | * rate_n_flags field. After receiving a block-ack, the driver can update | ||
1971 | * history for the entire block all at once. | ||
1972 | * | ||
1973 | * | ||
1974 | * FINDING BEST STARTING RATE: | ||
1975 | * | ||
1976 | * When working with a selected initial modulation mode (see below), the | ||
1977 | * driver attempts to find a best initial rate. The initial rate is the | ||
1978 | * first entry in the Link Quality command's rate table. | ||
1979 | * | ||
1980 | * 1) Calculate actual throughput (success ratio * expected throughput, see | ||
1981 | * table below) for current initial rate. Do this only if enough frames | ||
1982 | * have been attempted to make the value meaningful: at least 6 failed | ||
1983 | * tx attempts, or at least 8 successes. If not enough, don't try rate | ||
1984 | * scaling yet. | ||
1985 | * | ||
1986 | * 2) Find available rates adjacent to current initial rate. Available means: | ||
1987 | * a) supported by hardware && | ||
1988 | * b) supported by association && | ||
1989 | * c) within any constraints selected by user | ||
1990 | * | ||
1991 | * 3) Gather measured throughputs for adjacent rates. These might not have | ||
1992 | * enough history to calculate a throughput. That's okay, we might try | ||
1993 | * using one of them anyway! | ||
1994 | * | ||
1995 | * 4) Try decreasing rate if, for current rate: | ||
1996 | * a) success ratio is < 15% || | ||
1997 | * b) lower adjacent rate has better measured throughput || | ||
1998 | * c) higher adjacent rate has worse throughput, and lower is unmeasured | ||
1999 | * | ||
2000 | * As a sanity check, if decrease was determined above, leave rate | ||
2001 | * unchanged if: | ||
2002 | * a) lower rate unavailable | ||
2003 | * b) success ratio at current rate > 85% (very good) | ||
2004 | * c) current measured throughput is better than expected throughput | ||
2005 | * of lower rate (under perfect 100% tx conditions, see table below) | ||
2006 | * | ||
2007 | * 5) Try increasing rate if, for current rate: | ||
2008 | * a) success ratio is < 15% || | ||
2009 | * b) both adjacent rates' throughputs are unmeasured (try it!) || | ||
2010 | * b) higher adjacent rate has better measured throughput || | ||
2011 | * c) lower adjacent rate has worse throughput, and higher is unmeasured | ||
2012 | * | ||
2013 | * As a sanity check, if increase was determined above, leave rate | ||
2014 | * unchanged if: | ||
2015 | * a) success ratio at current rate < 70%. This is not particularly | ||
2016 | * good performance; higher rate is sure to have poorer success. | ||
2017 | * | ||
2018 | * 6) Re-evaluate the rate after each tx frame. If working with block- | ||
2019 | * acknowledge, history and statistics may be calculated for the entire | ||
2020 | * block (including prior history that fits within the history windows), | ||
2021 | * before re-evaluation. | ||
2022 | * | ||
2023 | * FINDING BEST STARTING MODULATION MODE: | ||
2024 | * | ||
2025 | * After working with a modulation mode for a "while" (and doing rate scaling), | ||
2026 | * the driver searches for a new initial mode in an attempt to improve | ||
2027 | * throughput. The "while" is measured by numbers of attempted frames: | ||
2028 | * | ||
2029 | * For legacy mode, search for new mode after: | ||
2030 | * 480 successful frames, or 160 failed frames | ||
2031 | * For high-throughput modes (SISO or MIMO), search for new mode after: | ||
2032 | * 4500 successful frames, or 400 failed frames | ||
2033 | * | ||
2034 | * Mode switch possibilities are (3 for each mode): | ||
2035 | * | ||
2036 | * For legacy: | ||
2037 | * Change antenna, try SISO (if HT association), try MIMO (if HT association) | ||
2038 | * For SISO: | ||
2039 | * Change antenna, try MIMO, try shortened guard interval (SGI) | ||
2040 | * For MIMO: | ||
2041 | * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) | ||
2042 | * | ||
2043 | * When trying a new mode, use the same bit rate as the old/current mode when | ||
2044 | * trying antenna switches and shortened guard interval. When switching to | ||
2045 | * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate | ||
2046 | * for which the expected throughput (under perfect conditions) is about the | ||
2047 | * same or slightly better than the actual measured throughput delivered by | ||
2048 | * the old/current mode. | ||
2049 | * | ||
2050 | * Actual throughput can be estimated by multiplying the expected throughput | ||
2051 | * by the success ratio (successful / attempted tx frames). Frame size is | ||
2052 | * not considered in this calculation; it assumes that frame size will average | ||
2053 | * out to be fairly consistent over several samples. The following are | ||
2054 | * metric values for expected throughput assuming 100% success ratio. | ||
2055 | * Only G band has support for CCK rates: | ||
2056 | * | ||
2057 | * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 | ||
2058 | * | ||
2059 | * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 | ||
2060 | * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 | ||
2061 | * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 | ||
2062 | * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 | ||
2063 | * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 | ||
2064 | * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 | ||
2065 | * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 | ||
2066 | * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 | ||
2067 | * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 | ||
2068 | * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 | ||
2069 | * | ||
2070 | * After the new mode has been tried for a short while (minimum of 6 failed | ||
2071 | * frames or 8 successful frames), compare success ratio and actual throughput | ||
2072 | * estimate of the new mode with the old. If either is better with the new | ||
2073 | * mode, continue to use the new mode. | ||
2074 | * | ||
2075 | * Continue comparing modes until all 3 possibilities have been tried. | ||
2076 | * If moving from legacy to HT, try all 3 possibilities from the new HT | ||
2077 | * mode. After trying all 3, a best mode is found. Continue to use this mode | ||
2078 | * for the longer "while" described above (e.g. 480 successful frames for | ||
2079 | * legacy), and then repeat the search process. | ||

2461 | /* | ||
2462 | * REPLY_SCAN_CMD = 0x80 (command) | ||
2463 | * | ||
2464 | * The hardware scan command is very powerful; the driver can set it up to | ||
2465 | * maintain (relatively) normal network traffic while doing a scan in the | ||
2466 | * background. The max_out_time and suspend_time control the ratio of how | ||
2467 | * long the device stays on an associated network channel ("service channel") | ||
2468 | * vs. how long it's away from the service channel, i.e. tuned to other channels | ||
2469 | * for scanning. | ||
2470 | * | ||
2471 | * max_out_time is the max time off-channel (in usec), and suspend_time | ||
2472 | * is how long (in "extended beacon" format) that the scan is "suspended" | ||
2473 | * after returning to the service channel. That is, suspend_time is the | ||
2474 | * time that we stay on the service channel, doing normal work, between | ||
2475 | * scan segments. The driver may set these parameters differently to support | ||
2476 | * scanning when associated vs. not associated, and light vs. heavy traffic | ||
2477 | * loads when associated. | ||
2478 | * | ||
2479 | * After receiving this command, the device's scan engine does the following; | ||
2480 | * | ||
2481 | * 1) Sends SCAN_START notification to driver | ||
2482 | * 2) Checks to see if it has time to do scan for one channel | ||
2483 | * 3) Sends NULL packet, with power-save (PS) bit set to 1, | ||
2484 | * to tell AP that we're going off-channel | ||
2485 | * 4) Tunes to first channel in scan list, does active or passive scan | ||
2486 | * 5) Sends SCAN_RESULT notification to driver | ||
2487 | * 6) Checks to see if it has time to do scan on *next* channel in list | ||
2488 | * 7) Repeats 4-6 until it no longer has time to scan the next channel | ||
2489 | * before max_out_time expires | ||
2490 | * 8) Returns to service channel | ||
2491 | * 9) Sends NULL packet with PS=0 to tell AP that we're back | ||
2492 | * 10) Stays on service channel until suspend_time expires | ||
2493 | * 11) Repeats entire process 2-10 until list is complete | ||
2494 | * 12) Sends SCAN_COMPLETE notification | ||
2495 | * | ||
2496 | * For fast, efficient scans, the scan command also has support for staying on | ||
2497 | * a channel for just a short time, if doing active scanning and getting no | ||
2498 | * responses to the transmitted probe request. This time is controlled by | ||
2499 | * quiet_time, and the number of received packets below which a channel is | ||
2500 | * considered "quiet" is controlled by quiet_plcp_threshold. | ||
2501 | * | ||
2502 | * For active scanning on channels that have regulatory restrictions against | ||
2503 | * blindly transmitting, the scan can listen before transmitting, to make sure | ||
2504 | * that there is already legitimate activity on the channel. If enough | ||
2505 | * packets are cleanly received on the channel (controlled by good_CRC_th, | ||
2506 | * typical value 1), the scan engine starts transmitting probe requests. | ||
2507 | * | ||
2508 | * Driver must use separate scan commands for 2.4 vs. 5 GHz bands. | ||
2509 | * | ||

3071 | /** | ||
3072 | * SENSITIVITY_CMD = 0xa8 (command, has simple generic response) | ||
3073 | * | ||
3074 | * This command sets up the Rx signal detector for a sensitivity level that | ||
3075 | * is high enough to lock onto all signals within the associated network, | ||
3076 | * but low enough to ignore signals that are below a certain threshold, so as | ||
3077 | * not to have too many "false alarms". False alarms are signals that the | ||
3078 | * Rx DSP tries to lock onto, but then discards after determining that they | ||
3079 | * are noise. | ||
3080 | * | ||
3081 | * The optimum number of false alarms is between 5 and 50 per 200 TUs | ||
3082 | * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e. | ||
3083 | * time listening, not transmitting). Driver must adjust sensitivity so that | ||
3084 | * the ratio of actual false alarms to actual Rx time falls within this range. | ||
3085 | * | ||
3086 | * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each | ||
3087 | * received beacon. These provide information to the driver to analyze the | ||
3088 | * sensitivity. Don't analyze statistics that come in from scanning, or any | ||
3089 | * other non-associated-network source. Pertinent statistics include: | ||
3090 | * | ||
3091 | * From "general" statistics (struct statistics_rx_non_phy): | ||
3092 | * | ||
3093 | * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level) | ||
3094 | * Measure of energy of desired signal. Used for establishing a level | ||
3095 | * below which the device does not detect signals. | ||
3096 | * | ||
3097 | * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB) | ||
3098 | * Measure of background noise in silent period after beacon. | ||
3099 | * | ||
3100 | * channel_load | ||
3101 | * uSecs of actual Rx time during beacon period (varies according to | ||
3102 | * how much time was spent transmitting). | ||
3103 | * | ||
3104 | * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately: | ||
3105 | * | ||
3106 | * false_alarm_cnt | ||
3107 | * Signal locks abandoned early (before phy-level header). | ||
3108 | * | ||
3109 | * plcp_err | ||
3110 | * Signal locks abandoned late (during phy-level header). | ||
3111 | * | ||
3112 | * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from | ||
3113 | * beacon to beacon, i.e. each value is an accumulation of all errors | ||
3114 | * before and including the latest beacon. Values will wrap around to 0 | ||
3115 | * after counting up to 2^32 - 1. Driver must differentiate vs. | ||
3116 | * previous beacon's values to determine # false alarms in the current | ||
3117 | * beacon period. | ||
3118 | * | ||
3119 | * Total number of false alarms = false_alarms + plcp_errs | ||
3120 | * | ||
3121 | * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd | ||
3122 | * (notice that the start points for OFDM are at or close to settings for | ||
3123 | * maximum sensitivity): | ||
3124 | * | ||
3125 | * START / MIN / MAX | ||
3126 | * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120 | ||
3127 | * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210 | ||
3128 | * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140 | ||
3129 | * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270 | ||
3130 | * | ||
3131 | * If actual rate of OFDM false alarms (+ plcp_errors) is too high | ||
3132 | * (greater than 50 for each 204.8 msecs listening), reduce sensitivity | ||
3133 | * by *adding* 1 to all 4 of the table entries above, up to the max for | ||
3134 | * each entry. Conversely, if false alarm rate is too low (less than 5 | ||
3135 | * for each 204.8 msecs listening), *subtract* 1 from each entry to | ||
3136 | * increase sensitivity. | ||
3137 | * | ||
3138 | * For CCK sensitivity, keep track of the following: | ||
3139 | * | ||
3140 | * 1). 20-beacon history of maximum background noise, indicated by | ||
3141 | * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the | ||
3142 | * 3 receivers. For any given beacon, the "silence reference" is | ||
3143 | * the maximum of last 60 samples (20 beacons * 3 receivers). | ||
3144 | * | ||
3145 | * 2). 10-beacon history of strongest signal level, as indicated | ||
3146 | * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers, | ||
3147 | * i.e. the strength of the signal through the best receiver at the | ||
3148 | * moment. These measurements are "upside down", with lower values | ||
3149 | * for stronger signals, so max energy will be *minimum* value. | ||
3150 | * | ||
3151 | * Then for any given beacon, the driver must determine the *weakest* | ||
3152 | * of the strongest signals; this is the minimum level that needs to be | ||
3153 | * successfully detected, when using the best receiver at the moment. | ||
3154 | * "Max cck energy" is the maximum (higher value means lower energy!) | ||
3155 | * of the last 10 minima. Once this is determined, driver must add | ||
3156 | * a little margin by adding "6" to it. | ||
3157 | * | ||
3158 | * 3). Number of consecutive beacon periods with too few false alarms. | ||
3159 | * Reset this to 0 at the first beacon period that falls within the | ||
3160 | * "good" range (5 to 50 false alarms per 204.8 milliseconds rx). | ||
3161 | * | ||
3162 | * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd | ||
3163 | * (notice that the start points for CCK are at maximum sensitivity): | ||
3164 | * | ||
3165 | * START / MIN / MAX | ||
3166 | * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200 | ||
3167 | * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400 | ||
3168 | * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100 | ||
3169 | * | ||
3170 | * If actual rate of CCK false alarms (+ plcp_errors) is too high | ||
3171 | * (greater than 50 for each 204.8 msecs listening), method for reducing | ||
3172 | * sensitivity is: | ||
3173 | * | ||
3174 | * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, | ||
3175 | * up to max 400. | ||
3176 | * | ||
3177 | * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160, | ||
3178 | * sensitivity has been reduced a significant amount; bring it up to | ||
3179 | * a moderate 161. Otherwise, *add* 3, up to max 200. | ||
3180 | * | ||
3181 | * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160, | ||
3182 | * sensitivity has been reduced only a moderate or small amount; | ||
3183 | * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX, | ||
3184 | * down to min 0. Otherwise (if gain has been significantly reduced), | ||
3185 | * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value. | ||
3186 | * | ||
3187 | * b) Save a snapshot of the "silence reference". | ||
3188 | * | ||
3189 | * If actual rate of CCK false alarms (+ plcp_errors) is too low | ||
3190 | * (less than 5 for each 204.8 msecs listening), method for increasing | ||
3191 | * sensitivity is used only if: | ||

3193 | * 1a) Previous beacon did not have too many false alarms | ||
3194 | * 1b) AND difference between previous "silence reference" and current | ||
3195 | * "silence reference" (prev - current) is 2 or more, | ||
3196 | * OR 2) 100 or more consecutive beacon periods have had rate of | ||
3197 | * less than 5 false alarms per 204.8 milliseconds rx time. | ||
3198 | * | ||
3199 | * Method for increasing sensitivity: | ||
3200 | * | ||
3201 | * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX, | ||
3202 | * down to min 125. | ||
3203 | * | ||
3204 | * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, | ||
3205 | * down to min 200. | ||
3206 | * | ||
3207 | * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100. | ||
3208 | * | ||
3209 | * If actual rate of CCK false alarms (+ plcp_errors) is within good range | ||
3210 | * (between 5 and 50 for each 204.8 msecs listening): | ||
3211 | * | ||
3212 | * 1) Save a snapshot of the silence reference. | ||
3213 | * | ||
3214 | * 2) If previous beacon had too many CCK false alarms (+ plcp_errors), | ||
3215 | * give some extra margin to energy threshold by *subtracting* 8 | ||
3216 | * from value in HD_MIN_ENERGY_CCK_DET_INDEX. | ||
3217 | * | ||
3218 | * For all cases (too few, too many, good range), make sure that the CCK | ||
3219 | * detection threshold (energy) is below the energy level for robust | ||
3220 | * detection over the past 10 beacon periods, the "Max cck energy". | ||
3221 | * Lower values mean higher energy; this means making sure that the value | ||
3222 | * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy". | ||

3262 | * This command sets the relative gains of 4965 device's 3 radio receiver chains. | ||
3263 | * | ||
3264 | * After the first association, driver should accumulate signal and noise | ||
3265 | * statistics from the STATISTICS_NOTIFICATIONs that follow the first 20 | ||
3266 | * beacons from the associated network (don't collect statistics that come | ||
3267 | * in from scanning, or any other non-network source). | ||
3268 | * | ||
3269 | * DISCONNECTED ANTENNA: | ||
3270 | * | ||

3272 | * average beacon signal levels for the 3 Rx chains. Accumulate (add) the | ||
3273 | * following values over 20 beacons, one accumulator for each of the chains | ||

3279 | * strongest. If any signal is more than 15 dB (times 20, unless you | ||
3280 | * divide the accumulated values by 20) below the strongest, the driver | ||
3281 | * considers that antenna to be disconnected, and should not try to use that | ||
3282 | * antenna/chain for Rx or Tx. If both A and B seem to be disconnected, | ||
3283 | * driver should declare the stronger one as connected, and attempt to use it | ||
3284 | * (A and B are the only 2 Tx chains!). | ||
3285 | * | ||
3286 | * | ||
3287 | * RX BALANCE: | ||
3288 | * | ||
3289 | * Driver should balance the 3 receivers (but just the ones that are connected | ||
3290 | * to antennas, see above) for gain, by comparing the average signal levels | ||
3291 | * detected during the silence after each beacon (background noise). | ||
3292 | * Accumulate (add) the following values over 20 beacons, one accumulator for | ||
3293 | * each of the chains a/b/c, from struct statistics_rx_non_phy: | ||
3294 | * | ||
3295 | * beacon_silence_rssi_[abc] & 0x0FF (unsigned, units in dB) | ||
3296 | * | ||
3297 | * Find the weakest background noise level from among a/b/c. This Rx chain | ||
3298 | * will be the reference, with 0 gain adjustment. Attenuate other channels by | ||
3299 | * finding noise difference: | ||
3300 | * | ||
3301 | * (accum_noise[i] - accum_noise[reference]) / 30 | ||
3302 | * | ||
3303 | * The "30" adjusts the dB in the 20 accumulated samples to units of 1.5 dB. | ||
3304 | * For use in diff_gain_[abc] fields of struct iwl_calibration_cmd, the | ||
3305 | * driver should limit the difference results to a range of 0-3 (0-4.5 dB), | ||

78 | /************************** EEPROM BANDS **************************** | ||
79 | * | ||
80 | * The iwl_eeprom_band definitions below provide the mapping from the | ||
81 | * EEPROM contents to the specific channel number supported for each | ||
82 | * band. | ||
83 | * | ||
84 | * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3 | ||
85 | * definition below maps to physical channel 42 in the 5.2GHz spectrum. | ||
86 | * The specific geography and calibration information for that channel | ||
87 | * is contained in the eeprom map itself. | ||
88 | * | ||
89 | * During init, we copy the eeprom information and channel map | ||
90 | * information into priv->channel_info_24/52 and priv->channel_map_24/52 | ||
91 | * | ||
92 | * channel_map_24/52 provides the index in the channel_info array for a | ||
93 | * given channel. We have to have two separate maps as there is channel | ||
94 | * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and | ||
95 | * band_2 | ||
96 | * | ||
97 | * A value of 0xff stored in the channel_map indicates that the channel | ||
98 | * is not supported by the hardware at all. | ||
99 | * | ||

117 | * Rx SRAM Control and Status Registers (RSCSR) | ||
118 | * | ||
119 | * These registers provide handshake between driver and 4965 for the Rx queue | ||
120 | * (this queue handles *all* command responses, notifications, Rx data, etc. | ||
121 | * sent from 4965 uCode to host driver). Unlike Tx, there is only one Rx | ||
122 | * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can | ||
123 | * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer | ||
124 | * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1 | ||
125 | * mapping between RBDs and RBs. | ||
126 | * | ||
127 | * Driver must allocate host DRAM memory for the following, and set the | ||
128 | * physical address of each into 4965 registers: | ||
129 | * | ||
130 | * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256 | ||
131 | * entries (although any power of 2, up to 4096, is selectable by driver). | ||
132 | * Each entry (1 dword) points to a receive buffer (RB) of consistent size | ||
133 | * (typically 4K, although 8K or 16K are also selectable by driver). | ||
134 | * Driver sets up RB size and number of RBDs in the CB via Rx config | ||
135 | * register FH_MEM_RCSR_CHNL0_CONFIG_REG. | ||
136 | * | ||
137 | * Bit fields within one RBD: | ||
138 | * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned | ||
139 | * | ||
140 | * Driver sets physical address [35:8] of base of RBD circular buffer | ||
141 | * into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0]. | ||
142 | * | ||
143 | * 2) Rx status buffer, 8 bytes, in which 4965 indicates which Rx Buffers | ||
144 | * (RBs) have been filled, via a "write pointer", actually the index of | ||
145 | * the RB's corresponding RBD within the circular buffer. Driver sets | ||
146 | * physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0]. | ||
147 | * | ||
148 | * Bit fields in lower dword of Rx status buffer (upper dword not used | ||
149 | * by driver; see struct iwl4965_shared, val0): | ||
150 | * 31-12: Not used by driver | ||
151 | * 11- 0: Index of last filled Rx buffer descriptor | ||
152 | * (4965 writes, driver reads this value) | ||
153 | * | ||
154 | * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must | ||
155 | * enter pointers to these RBs into contiguous RBD circular buffer entries, | ||
156 | * and update the 4965's "write" index register, | ||
157 | * FH_RSCSR_CHNL0_RBDCB_WPTR_REG. | ||
158 | * | ||
159 | * This "write" index corresponds to the *next* RBD that the driver will make | ||
160 | * available, i.e. one RBD past the tail of the ready-to-fill RBDs within | ||
161 | * the circular buffer. This value should initially be 0 (before preparing any | ||
162 | * RBs), should be 8 after preparing the first 8 RBs (for example), and must | ||
163 | * wrap back to 0 at the end of the circular buffer (but don't wrap before | ||
164 | * "read" index has advanced past 1! See below). | ||
165 | * NOTE: 4965 EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8. | ||
166 | * | ||
167 | * As the 4965 fills RBs (referenced from contiguous RBDs within the circular | ||
168 | * buffer), it updates the Rx status buffer in host DRAM, 2) described above, | ||
169 | * to tell the driver the index of the latest filled RBD. The driver must | ||
170 | * read this "read" index from DRAM after receiving an Rx interrupt from 4965. | ||
171 | * | ||
172 | * The driver must also internally keep track of a third index, which is the | ||
173 | * next RBD to process. When receiving an Rx interrupt, driver should process | ||
174 | * all filled but unprocessed RBs up to, but not including, the RB | ||
175 | * corresponding to the "read" index. For example, if "read" index becomes "1", | ||
176 | * driver may process the RB pointed to by RBD 0. Depending on volume of | ||
177 | * traffic, there may be many RBs to process. | ||
178 | * | ||
179 | * If read index == write index, 4965 thinks there is no room to put new data. | ||
180 | * Due to this, the maximum number of filled RBs is 255, instead of 256. To | ||
181 | * be safe, make sure that there is a gap of at least 2 RBDs between "write" | ||
182 | * and "read" indexes; that is, make sure that there are no more than 254 | ||
183 | * buffers waiting to be filled. | ||

102 | * BSM (Bootstrap State Machine) | ||
103 | * | ||
104 | * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program | ||
105 | * in special SRAM that does not power down when the embedded control | ||
106 | * processor is sleeping (e.g. for periodic power-saving shutdowns of radio). | ||
107 | * | ||
108 | * When powering back up after sleeps (or during initial uCode load), the BSM | ||
109 | * internally loads the short bootstrap program from the special SRAM into the | ||
110 | * embedded processor's instruction SRAM, and starts the processor so it runs | ||
111 | * the bootstrap program. | ||
112 | * | ||
113 | * This bootstrap program loads (via PCI busmaster DMA) instructions and data | ||
114 | * images for a uCode program from host DRAM locations. The host driver | ||
115 | * indicates DRAM locations and sizes for instruction and data images via the | ||
116 | * four BSM_DRAM_* registers. Once the bootstrap program loads the new program, | ||
117 | * the new program starts automatically. | ||
118 | * | ||
119 | * The uCode used for open-source drivers includes two programs: | ||
120 | * | ||
121 | * 1) Initialization -- performs hardware calibration and sets up some | ||
122 | * internal data, then notifies host via "initialize alive" notification | ||
123 | * (struct iwl_init_alive_resp) that it has completed all of its work. | ||
124 | * After signal from host, it then loads and starts the runtime program. | ||
125 | * The initialization program must be used when initially setting up the | ||
126 | * NIC after loading the driver. | ||
127 | * | ||
128 | * 2) Runtime/Protocol -- performs all normal runtime operations. This | ||
129 | * notifies host via "alive" notification (struct iwl_alive_resp) that it | ||
130 | * is ready to be used. | ||
131 | * | ||
132 | * When initializing the NIC, the host driver does the following procedure: | ||
133 | * | ||
134 | * 1) Load bootstrap program (instructions only, no data image for bootstrap) | ||
135 | * into bootstrap memory. Use dword writes starting at BSM_SRAM_LOWER_BOUND | ||
136 | * | ||
137 | * 2) Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction | ||
138 | * images in host DRAM. | ||
139 | * | ||
140 | * 3) Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked: | ||
141 | * BSM_WR_MEM_SRC_REG = 0 | ||
142 | * BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND | ||
143 | * BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image | ||
144 | * | ||
145 | * 4) Load bootstrap into instruction SRAM: | ||
146 | * BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START | ||
147 | * | ||
148 | * 5) Wait for load completion: | ||
149 | * Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0 | ||
150 | * | ||
151 | * 6) Enable future boot loads whenever NIC's power management triggers it: | ||
152 | * BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN | ||
153 | * | ||
154 | * 7) Start the NIC by removing all reset bits: | ||
155 | * CSR_RESET = 0 | ||
156 | * | ||
157 | * The bootstrap uCode (already in instruction SRAM) loads initialization | ||
158 | * uCode. Initialization uCode performs data initialization, sends | ||
159 | * "initialize alive" notification to host, and waits for a signal from | ||
160 | * host to load runtime code. | ||
161 | * | ||
162 | * 4) Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction | ||
163 | * images in host DRAM. The last register loaded must be the instruction | ||
164 | * byte count register ("1" in MSbit tells initialization uCode to load | ||
165 | * the runtime uCode): | ||
166 | * BSM_DRAM_INST_BYTECOUNT_REG = byte count | BSM_DRAM_INST_LOAD | ||
167 | * | ||
168 | * 5) Wait for "alive" notification, then issue normal runtime commands. | ||
169 | * | ||
170 | * Data caching during power-downs: | ||
171 | * | ||
172 | * Just before the embedded controller powers down (e.g for automatic | ||
173 | * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA) | ||
174 | * a current snapshot of the embedded processor's data SRAM into host DRAM. | ||
175 | * This caches the data while the embedded processor's memory is powered down. | ||
176 | * Location and size are controlled by BSM_DRAM_DATA_* registers. | ||
177 | * | ||
178 | * NOTE: Instruction SRAM does not need to be saved, since that doesn't | ||
179 | * change during operation; the original image (from uCode distribution | ||
180 | * file) can be used for reload. | ||
181 | * | ||
182 | * When powering back up, the BSM loads the bootstrap program. Bootstrap looks | ||
183 | * at the BSM_DRAM_* registers, which now point to the runtime instruction | ||
184 | * image and the cached (modified) runtime data (*not* the initialization | ||
185 | * uCode). Bootstrap reloads these runtime images into SRAM, and restarts the | ||
186 | * uCode from where it left off before the power-down. | ||
187 | * | ||
188 | * NOTE: Initialization uCode does *not* run as part of the save/restore | ||
189 | * procedure. | ||
190 | * | ||
191 | * This save/restore method is mostly for autonomous power management during | ||
192 | * normal operation (result of POWER_TABLE_CMD). Platform suspend/resume and | ||
193 | * RFKILL should use complete restarts (with total re-initialization) of uCode, | ||
194 | * allowing total shutdown (including BSM memory). | ||
195 | * | ||
196 | * Note that, during normal operation, the host DRAM that held the initial | ||
197 | * startup data for the runtime code is now being used as a backup data cache | ||
198 | * for modified data! If you need to completely re-initialize the NIC, make | ||
199 | * sure that you use the runtime data image from the uCode distribution file, | ||
200 | * not the modified/saved runtime data. You may want to store a separate | ||
201 | * "clean" runtime data image in DRAM to avoid disk reads of distribution file. | ||

248 | * Tx Scheduler | ||
249 | * | ||
250 | * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs | ||
251 | * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in | ||
252 | * host DRAM. It steers each frame's Tx command (which contains the frame | ||
253 | * data) into one of up to 7 prioritized Tx DMA FIFO channels within the | ||
254 | * device. A queue maps to only one (selectable by driver) Tx DMA channel, | ||
255 | * but one DMA channel may take input from several queues. | ||
256 | * | ||
257 | * Tx DMA FIFOs have dedicated purposes. For 4965, they are used as follows | ||
258 | * (cf. default_queue_to_tx_fifo in iwl-4965.c): | ||
259 | * | ||
260 | * 0 -- EDCA BK (background) frames, lowest priority | ||
261 | * 1 -- EDCA BE (best effort) frames, normal priority | ||
262 | * 2 -- EDCA VI (video) frames, higher priority | ||
263 | * 3 -- EDCA VO (voice) and management frames, highest priority | ||
264 | * 4 -- Commands (e.g. RXON, etc.) | ||
265 | * 5 -- unused (HCCA) | ||
266 | * 6 -- unused (HCCA) | ||
267 | * 7 -- not used by driver (device-internal only) | ||
268 | * | ||
269 | * | ||
270 | * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6. | ||
271 | * In addition, driver can map the remaining queues to Tx DMA/FIFO | ||
272 | * channels 0-3 to support 11n aggregation via EDCA DMA channels. | ||
273 | * | ||
274 | * The driver sets up each queue to work in one of two modes: | ||
275 | * | ||
276 | * 1) Scheduler-Ack, in which the scheduler automatically supports a | ||
277 | * block-ack (BA) window of up to 64 TFDs. In this mode, each queue | ||
278 | * contains TFDs for a unique combination of Recipient Address (RA) | ||
279 | * and Traffic Identifier (TID), that is, traffic of a given | ||
280 | * Quality-Of-Service (QOS) priority, destined for a single station. | ||
281 | * | ||
282 | * In scheduler-ack mode, the scheduler keeps track of the Tx status of | ||
283 | * each frame within the BA window, including whether it's been transmitted, | ||
284 | * and whether it's been acknowledged by the receiving station. The device | ||
285 | * automatically processes block-acks received from the receiving STA, | ||
286 | * and reschedules un-acked frames to be retransmitted (successful | ||
287 | * Tx completion may end up being out-of-order). | ||
288 | * | ||
289 | * The driver must maintain the queue's Byte Count table in host DRAM | ||
290 | * (struct iwl4965_sched_queue_byte_cnt_tbl) for this mode. | ||
291 | * This mode does not support fragmentation. | ||
292 | * | ||
293 | * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order. | ||
294 | * The device may automatically retry Tx, but will retry only one frame | ||
295 | * at a time, until receiving ACK from receiving station, or reaching | ||
296 | * retry limit and giving up. | ||
297 | * | ||
298 | * The command queue (#4/#9) must use this mode! | ||
299 | * This mode does not require use of the Byte Count table in host DRAM. | ||
300 | * | ||
301 | * Driver controls scheduler operation via 3 means: | ||
302 | * 1) Scheduler registers | ||
303 | * 2) Shared scheduler data base in internal 4956 SRAM | ||
304 | * 3) Shared data in host DRAM | ||
305 | * | ||
306 | * Initialization: | ||
307 | * | ||
308 | * When loading, driver should allocate memory for: | ||
309 | * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs. | ||
310 | * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory | ||
311 | * (1024 bytes for each queue). | ||
312 | * | ||
313 | * After receiving "Alive" response from uCode, driver must initialize | ||
314 | * the scheduler (especially for queue #4/#9, the command queue, otherwise | ||
315 | * the driver can't issue commands!): | ||

41 | /* | ||
42 | * Rx theory of operation | ||
43 | * | ||
44 | * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs), | ||
45 | * each of which point to Receive Buffers to be filled by the NIC. These get | ||
46 | * used not only for Rx frames, but for any command response or notification | ||
47 | * from the NIC. The driver and NIC manage the Rx buffers by means | ||
48 | * of indexes into the circular buffer. | ||
49 | * | ||
50 | * Rx Queue Indexes | ||
51 | * The host/firmware share two index registers for managing the Rx buffers. | ||
52 | * | ||
53 | * The READ index maps to the first position that the firmware may be writing | ||
54 | * to -- the driver can read up to (but not including) this position and get | ||
55 | * good data. | ||
56 | * The READ index is managed by the firmware once the card is enabled. | ||
57 | * | ||
58 | * The WRITE index maps to the last position the driver has read from -- the | ||
59 | * position preceding WRITE is the last slot the firmware can place a packet. | ||
60 | * | ||
61 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | ||
62 | * WRITE = READ. | ||
63 | * | ||
64 | * During initialization, the host sets up the READ queue position to the first | ||
65 | * INDEX position, and WRITE to the last (READ - 1 wrapped) | ||
66 | * | ||
67 | * When the firmware places a packet in a buffer, it will advance the READ index | ||
68 | * and fire the RX interrupt. The driver can then query the READ index and | ||
69 | * process as many packets as possible, moving the WRITE index forward as it | ||
70 | * resets the Rx queue buffers with new memory. | ||
71 | * | ||
72 | * The management in the driver is as follows: | ||
73 | * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When | ||
74 | * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled | ||
75 | * to replenish the iwl->rxq->rx_free. | ||
76 | * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the | ||
77 | * iwl->rxq is replenished and the READ INDEX is updated (updating the | ||
78 | * 'processed' and 'read' driver indexes as well) | ||
79 | * + A received packet is processed and handed to the kernel network stack, | ||
80 | * detached from the iwl->rxq. The driver 'processed' index is updated. | ||
81 | * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free | ||
82 | * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ | ||
83 | * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there | ||
84 | * were enough free buffers and RX_STALLED is set it is cleared. | ||
85 | * | ||
86 | * | ||
87 | * Driver sequence: | ||
88 | * | ||
89 | * iwl_legacy_rx_queue_alloc() Allocates rx_free | ||
90 | * iwl_rx_replenish() Replenishes rx_free list from rx_used, and calls | ||
91 | * iwl_rx_queue_restock | ||
92 | * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx | ||
93 | * queue, updates firmware pointers, and updates | ||
94 | * the WRITE index. If insufficient rx_free buffers | ||
95 | * are available, schedules iwl_rx_replenish | ||
96 | * | ||
97 | * -- enable interrupts -- | ||
98 | * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the | ||
99 | * READ INDEX, detaching the SKB from the pool. | ||
100 | * Moves the packet buffer from queue to rx_used. | ||
101 | * Calls iwl_rx_queue_restock to refill any empty | ||
102 | * slots. | ||
