2010-11-30ath5k: Reset cleanup and generic cleanupNick Kossifidis
* No functional changes * Clean up reset: Introduce init functions for each unit and call them instead of having everything inside ath5k_hw_reset (it's just c/p for now so nothing changes except calling order -I tested it with various cards and it's ok-) * Further cleanups: ofdm_timings belongs to phy.c rate_duration belongs to pcu.c clock functions are general and belong to reset.c (more to follow) * Reorder functions for better organization: We start with helpers and other functions follow in categories, init functions are last Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2010-11-22ath5k: Use static constJoe Perches
Using static const generally increases object text and decreases data size. It also generally decreases overall object size. text data bss dec hex filename 11266 56 2464 13786 35da drivers/net/wireless/ath/ath5k/ani.o.old 11181 56 2464 13701 3585 drivers/net/wireless/ath/ath5k/ani.o.new Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: John W.

2010-08-24ath5k: clean up some commentsBob Copeland
This fixes a few misspellings, word repetitions, and some grammar nits in ath5k comments. No code changes. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-06-02ath5k: print error message if ANI levels are out of rangeBruno Randolf
Since we have sysfs to manually set the ANI levels, we should print errors to the kernel log if the values are out of bounds. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-06-02ath5k: always calculate ANI listen timeBruno Randolf
Calculate 'listen' time also when automatic ANI is off, since this and the "busy" time is useful information also in manual mode. Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-04-07ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
