| | | | | | | | | | | The commit, "ath9k_hw: improve ANI processing and rx desensitizing parameters" removed code setting various phy registers holding threshold values. This is likely required for OFDM weak signal detection to function correctly, so add them, but skip AR9462 and AR9565.

* | ath9k: add spectral scan featureSimon Wunderlich2013-01-091-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the spectral scan feature for ath9k. AR92xx and AR93xx chips are supported for now. The spectral scan is triggered by configuring a mode through a debugfs control file. Samples can be gathered via another relay debugfs file. Essentially, to try it out: echo chanscan > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl iw dev wlan0 scan cat /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 > samples echo disable > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl This feature is still experimental. The special "chanscan" mode is used to perform spectral scan while mac80211 is scanning for channels. To allow this, sw_scan_start/complete() ops have been added. The patch contains code snippets and information from Zefir Kurtisi and information provided by Adrian Chadd and Felix Fietkau.

| * Revert "ath9k_hw: Fix incorrect spur_freq_sd for AR9003"Rajkumar Manoharan2012-05-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit a844adfd7bee4edc66d337de6c33b348e83552a8. The commit a844adfd is degrading rx sensitivity of lower rate in HT40 mode and it is confirmed that reverting the change is improving rx sensitivity. spur_freq_sd (for self-corr in AGC) is defined with respect to the center of each 20MHz channel while spur_phase_delta (for self-corr in Rx and spur data filter) is defined with respect to the center of current RF channel. So in short, we need to subtract spur_freq_sd (for self-corr in AGC) by the offset between the center of primary20 and the center of RF channel in SW. This offset could be +/10 MHz for dynamic 40.

| * ath9k: add an extra boolean parameter to ath9k_hw_apply_txpowerGabor Juhos2012-04-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.'

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAX_TXPWR table for BTCOEX is not needed for AR9462. Programming these values to the HW results in undesirable behavior - for example, large number of delimiter/data underruns are seen in AES-CCMP mode. Also, registers like AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX power table is programmed to the HW, and frames being transmitted end up being looped back to the RX engine, an example being beacon frames in IBSS mode. Remove this table for now - this fixes CCMP performance and general IBSS usage. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

|/ | | | | | | | | | | | | | | | | | | | | | 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.
