2012-04-23ath9k: add an extra boolean parameter to ath9k_hw_apply_txpowerGabor Juhos
In order to unifying regulatory limit handling commit ca2c68cc7bc80fc4504fb420df04cce99c9ee6ec (ath9k_hw: clean up tx power handling) introduced a new helper function 'ath9k_hw_apply_txpower', and the direct calls of 'ah->eep_ops->set_txpower' has been replaced by a call of the helper function. This caused a change in the behaviour of the 'ath9k_hw_set_txpowerlimit' function. The purpose of that function is to calculate and store the rate txpower table and the regulatory limit without touching the hardware registers. Before the commit, the 'test' parameter of the function was passed to the 'ah->eep_ops->set_txpower'. Now the calling of the 'set_txpower' function happens indirectly through 'ath9k_hw_apply_txpower', so the 'test' argument of the 'set_txpower' is always 'false'. This patch restores the original behaviour of 'ath9k_hw_set_txpowerlimit' by adding a new argument to 'ath9k_hw_apply_txpower.'

2012-04-09ath9k_hw: improve ANI processing and rx desensitizing parametersRajkumar Manoharan
This patch improves ANI operations by switching among the immunity levels based on PHY errors and beacon rssi which will adjust receiver desensitizing parameters. The changes are * Configure the Weak Signal Detection based on current immunity value. * At highest OFDM immunity level poor performance was observed with strong interference. By tuning the FIR step and spur immunity levels and not changing any weak signal detection thresholds at any level helped to improve the performance. * ANI took long time to recover back to lower immunity levels on heavy data load. As the listen time got reset to zero before reaching to the 5x of aniperiod, the immunity level is not lowering back even without any interference. This patch fix that.

2011-10-11ath9k_hw: clean up tx power handlingFelix Fietkau
The code for handling various restrictions concerning regulatory limits, antenna gain, etc. is very convoluted and duplicated across various EEPROM parsing implementations, making it hard to review. This patch partially cleans up the mess by unifying regulatory limit handling in one function and simplifying handling of antenna gain. It also removes unused transmit power scaling arrays from the EEPROM code, which belonged to an unimplemented API that isn't supposed to be in the driver anyway.

2011-03-30ath9k_hw: Speedup register ops for HTC driverRajkumar Manoharan
Fine-tuning register write operation and avoid unnecessay delays for ath9k_htc driver, saves hw reset time which improves scanning time and also solves one of the following scenario. Sometimes the ACK is sent by STA for assoc response is not seen at AP side. So the AP continues to send retry assoc responses. At the STA side, since the assoc response was already forwarded to mac80211, it proceeded to channel change which in turns does chip reset. In most of the cases the chip reset was completed before max retries are reached at AP side. Hence STA can able to ACK the retried frames again. But in clear environment these retries are completed within shortspan of time. Since ath9k_htc consumes more time for hw reset, this latency is causing dissociation by AP due to max reties are reached. This issue was originally reported with Cisco Aironet 1250 AP in HT40 mode in noise free environment. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to turn off based on GPIO input, however that code was hardcoded to GPIO 0 instead of ah->rfkill_gpio.

In the future, we want to use these counters to determine the medium utilization and export this information via survey.

2010-07-12ath9k: merge noisefloor load implementationsFelix Fietkau
AR5008+ and AR9003 currently use two separate implementations of the ath9k_hw_loadnf function. There are three main differences: - PHY registers for AR9003 are different - AR9003 always uses 3 chains, earlier versions are more selective - The AR9003 variant contains a fix for NF load timeouts This patch merges the two implementations into one, storing the register array in the ath_hw struct. The fix for NF load timeouts is not just relevant for AR9003, but also important for earlier hardware, so it's better to just keep one common implementation.
