* ath9k: resume aggregation immediately after a hardware resetFelix Fietkau2010-10-253-4/+4
| | | | | | | | | | | | Since aggregation is usually triggered by tx completion, a hardware reset (because of beacon stuck, tx hang or baseband hang) can significantly delay the transmission of the next AMPDU (until the next tx completion event). Fix this by rescheduling aggregation after such a reset. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: fix handling of rate control probe framesFelix Fietkau2010-10-251-0/+6
| | | | | | | | | | | The ath9k aggregation code was already checking the rate control probe flag to prevent starting an aggregate frame with a sampling rate. What was missing was closing an aggregate before adding a probing frame to it. Without that, rate control cannot have precise control over probing, which delays using faster rates when the channel conditions improve.

* ath9k_hw: Fix TX carrier leakage for IEEE compliance on AR9003 2.2Luis R. Rodriguez2010-10-251-56/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the initvals for the AR9003 2.2 chipsets. The initvals are the initial register values we use for our registers upon hardware reset. This synchs up the initvals to match what our latest recommendation from our systems engineering team. The description of changes in this update: Improves ability to support very strong Rx conditions. Enhances DFS support for AP-mode. Improves performance of Tx carrier leak calibration. Adds support for Japan channel 14 Tx filtering requirements. Improves Tx power accuracy. Impact: Update required to address degraded throughput at very short range. Update required for AP-mode DFS certification. Update required to comply to IEEE Tx carrier leak specification. May not meet expected +/- 2 dB Tx power accuracy without update. The most important fix here would be the TX carrier leakage required to comply with IEEE 802.11 specifications. The group of changes have been tested all together in one release.

| * ath9k: A-MPDU rate control info fixBjörn Smedman2010-10-111-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the following problems with the rate control feedback generated by ath9k for A-MPDU frames: 1. Rate control feedback is carried on the first frame of an aggregate that is either ACKed, or has execeeded the software retry count and is considered failed. However, ath9k would incorrectly assume the aggregate had the length 1 if one of these conditions did not apply to the first frame of the aggregate, but instead a later frame. This fix therefor copies the bf_nframes field of the buffer in the same manner as the rates field of the tx status. 2. Sometimes the ampdu_len and ampdu_ack_len fields of the tx status was left uninitialized eventhough the IEEE80211_TX_STAT_AMPDU flag was set. This is now avoid by setting flag and fields in the same place. 3. Even if a frame has been selected for aggregation by mac80211 and marked with the IEEE80211_TX_CTL_AMPDU flag it can sometimes happen that ath9k transmits the frame without aggregation. In these cases the ampdu_ack_len field could be incorrectly computed because the nbad parameter to ath_tx_rc_status was incorrect.

| * ath9k_hw: clean up ANI state handlingFelix Fietkau2010-10-066-260/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ANI state is kept per channel, so instead of keeping an array of ANI states with an arbitrary size of 255, move the ANI state into the channel struct. Move some config settings that are not per-channel out of the per-channel struct to save some memory. With those changes, ath9k_ani_restart_old and ath9k_ani_restart_new can be merged into a single function. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| * ath9k_hw: clean up register write bufferingFelix Fietkau2010-10-0611-58/+6
| | | | | | | | | | | | | | | | | | | | Throughout the code, DISABLE_REGWRITE_BUFFER is always called right after REGWRITE_BUFFER_FLUSH. Since that's unlikely to change any time soon, that makes keeping those ops separate rather pointless, as it only increases code size and line number counts.

| * ath9k_hw: merge codepaths that access the cycle counter registersFelix Fietkau2010-10-065-92/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | The cycle counters are used by ANI to determine the amount of time that the radio spent not receiving or transmitting. They're also used for debugging purposes if the baseband watchdog on AR9003 detects a lockup. In the future, we want to use these counters to determine the medium utilization and export this information via survey. For that, we need to make sure that the counter is only accessed from one place, which also ensures that wraparounds won't occur at inconvenient points in time.

| * ath9k_hw: clean up calibration flagsFelix Fietkau2010-10-066-77/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The calibration actual calibration flags are only used by the per chip family source files, so it makes more sense to define them in those files instead of globally. That way the code has to test for less flags. Also instead of using a separate callback for testing whether a particular calibration type is supported, simply adjust ah->supp_cals in the calibration init which is called right after the hardware reset, before any of the calibrations are run.

| * | ath9k: get correct tx gain type in ath9k_hw_4k_get_eepromGabor Juhos2010-10-051-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The base_eep_header_4k structure contains information that the device supports high power tx gain table or not. However the ath9k_hw_4k_get_eeprom function does not return that value when it is called with EEP_TXGAIN_TYPE. This leads to that the tx gain initialization will use the init values from the original tx gain table even if the device inidicates that the high power table should be used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the ath9k debugging feature 'wiphy' the current channel used by the station is incorrectly displayed.This is because the channels available are sequentially mapped from numbers 0 to 37.This mapping cannot be changed as the channel number is also used as an array index This fix solves the above problem by calculating the channel number from center frequency.
