2015-07-21ath9k: make DMA stop related messages debug-onlyFelix Fietkau
A long time ago, ath9k had issues during reset where the DMA engine would stay active and could potentially corrupt memory. To debug those issues, the driver would print warnings whenever they occur. Nowadays, these issues are gone and the primary cause of these messages is if the MAC is stuck during reset or busy processing a long transmission. This is fairly harmless, yet these messages continue to worry users. To reduce the number of bogus bug reports, turn these messages into debug messages and count their occurence in the "reset" debugfs file.

2014-02-12ath9k: Remove ath9k rate controlSujith Manoharan
There is no benefit in retaining the legacy rate control module in the driver codebase. It is known to be buggy and has less than optimal performance in real-world environments compared with minstrel. The only reason that it was kept when we made the switch to minstrel as default was that it showed higher throughput numbers in a clean/ideal environment. This is no longer the case and minstrel can push ath9k to the same throughput levels. In TCP, with 3-stream cards, more than 295 Mbps can be obtained in open air, with 2-stream cards, 210 Mbps is easily reached. To test performance issues, instead of using a broken rate control module, it is better to use the fixed-rate interface provided by mac80211 anyway. The ath9k RC has not received any bug fixes in years and is just bit-rotting away - this patch removes it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

2014-01-13ath9k: Process GTT interruptsSujith Manoharan
Global Transmission Timeout interrupts are generated by the HW when transmission of a frame fails - this is done based on the threshold programmed in the AR_GTXTO register. Currently, even though the interrupt is enabled for all chips, it is not handled in the driver. This patch handles GTT events for AR9003 and above chips, checking if the MAC/BB has hung after successive GTT interrupts crosses a threshold (5). This can be enabled for the older chips in the AR9002 family once appropriate HW hang checks are implemented for them.

2013-01-09ath9k: add spectral scan featureSimon Wunderlich
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.

This patch keep track of number of samples that includes DMA debugs registers, PCU observe, CR, channel noise, cycle conters, noisefloor history buffer and last N number of tx and rx descriptor status. These samples are grouped in table manner which dumping in debgufs.

2011-01-28ath9k: fix tx queue index confusion in debugfs codeFelix Fietkau
Various places printing tx queue information used various different ways to get a tx queue index for printing statistics. Most of these ways were wrong. ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only used internally for queue assignment. One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however this array uses the ath9k_hw queue number as well. Fix all of this by always using the ath9k_hw queue number as an index, and always looking it up by going through sc->tx.txq_map.
