2010-08-04ath9k_hw: Fix regulatory CTL index usage for AR9003Luis R. Rodriguez
AR9003 was not relying on the CTL indexes from the EEPROM for capping the max output power. The CTL indexes from the EEPROM provide calibrated limits for output power for each tested and supported frequency. Without this the device operates at a power level which only conforms to the transmit spectrum mask as specified by IEEE Annex I.2.3. The regulatory limit by CRDA is always used but does not provide calibrated values for optimal performance, specially on band edges. Using the calibrated data from the EEPROM ensures the device operates at optimal output power while still ensuring proper regulatory compliance. The device uses the minimum of these tree values, the value from CRDA, the calibrated value from CTL indexex, and the value to conform to the IEEE transmit spectrum mask. Signed-off-by: Luis R.

2010-08-04ath9k_hw: fix a noise floor calibration related race conditionFelix Fietkau
On AR5008-AR9002, other forms of calibration must not be started while the noise floor calibration is running, as this can create invalid readings which were sometimes not even recoverable by any further calibration attempts. This patch also ensures that the result of noise floor measurements are processed faster and also allows the result of the initial calibration on reset to make it into the NF history buffer Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-08-04ath9k_hw: clean up per-channel calibration dataFelix Fietkau
The noise floor history buffer is currently not kept per channel, which can lead to problems when changing channels from a clean channel to a noisy one. Also when switching from HT20 to HT40, the noise floor history buffer is full of measurements, but none of them contain data for the extension channel, which it needs quite a bit of time to recover from. This patch puts all the per-channel calibration data into a single data structure, and gives the the driver control over whether that is used per-channel or even not used for some channels. For ath9k_htc, I decided to keep this per-channel in order to avoid creating regressions. For ath9k, the data is kept only for the operating channel, which saves some space. ath9k_hw takes care of wiping old data when the operating channel or its channel flags change.

2010-08-04ath9k: prevent calibration during off-channel activityFelix Fietkau
Previously the software scan callback was used to indicate to the hardware, when it was safe to calibrate. This didn't really work properly, because it depends on a specific order of software scan callbacks vs. channel changes. Also, software scans are not the only thing that triggers off-channel activity, so it's better to use the newly added indication from mac80211 for this and not use the software scan callback for anything calibration related. This fixes at least some of the invalid noise floor readings that I've seen in AP mode on AR9160 Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-08-04ath9k_hw: fix periodic noise floor calibration on AR9003Felix Fietkau
The periodic noise floor calibration is broken on this chip family, because it keeps triggering a software-filtered noise floor calibration, but never reads the result before uploading the history buffer value to the hardware. Fix this with a call to ath9k_hw_getnf(), just like on AR9002. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Acked-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

2010-08-04ath9k_hw: clean up and fix initial noise floor calibrationFelix Fietkau
On AR9003 the initial noise floor calibration is currently triggered at the end of the reset without allowing the hardware to update the baseband settings. This could potentially make scans in noisy environments a bit more unreliable, so use the same calibration sequence that is used on AR9002.

2010-07-29iwlwifi: fix scan abortStanislaw Gruszka
Fix possible double priv->mutex lock introduced by commit a69b03e941abae00380fc6bc1877fb797a1b31e6 "iwlwifi: cancel scan watchdog in iwl_bg_abort_scan" . We can not call cancel_delayed_work_sync(&priv->scan_check) with priv->mutex locked because workqueue function iwl_bg_scan_check() take that lock internally. We do not need to synchronize when canceling priv->scan_check work. We can avoid races (sending double abort command or send no command at all) using STATUS_SCAN_ABORT bit. Moreover current iwl_bg_scan_check() code seems to be broken, as we should not send abort commands when currently aborting.

When issuing two consecutive scans you could often end up getting in the logs: "ath9k: Two wiphys trying to scan at the same time" This message is due to a race in mac80211 but addressing that race requires some more major changes on the driver and perhaps optimizations on mac80211 like removing the scan complete callback alltogether. Its too late to address this this kernel release so supress the complaint and annotate this needs fixing for later. Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luis R.
