* ath9k: replace snprintf() with scnprintf()Zefir Kurtisi2013-09-26
| | | | | | | | | | | | Whenever the return value of snprintf() is used to calculate remaining buffer-space, we wanted to use sncprintf() instead. Indentation is adapted where possible. Some lines exceed the line width limit, either they did it already before, or since they can not be broken reasonably well.

* | ath9k: add spectral scan featureSimon Wunderlich2013-01-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

* ath9k: rework tx queue selection and fix queue stopping/wakingFelix Fietkau2010-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ath9k tx queue handling code showed a few issues that could lead to locking issues, tx stalls due to stopped queues, and maybe even DMA issues. The main source of these issues is that in some places the queue is selected via skb queue mapping in places where this mapping may no longer be valid. One such place is when data frames are transmitted via the CAB queue (for powersave buffered frames). This is made even worse by a lookup WMM AC values from the assigned tx queue (which is undefined for the CAB queue). This messed up the pending frame counting, which in turn caused issues with queues getting stopped, but not woken again. To fix these issues, this patch removes an unnecessary abstraction separating a driver internal queue number from the skb queue number (not to be confused with the hardware queue number). It seems that this abstraction may have been necessary because of tx queue preinitialization from the initvals. This patch avoids breakage here by pushing the software <-> hardware queue mapping to the function that assigns the tx queues and redefining the WMM AC definitions to match the numbers used by mac80211 (also affects ath9k_htc). To ensure consistency wrt. pending frame count tracking, these counters are moved to the ath_txq struct, updated with the txq lock held, but only where the tx queue selected by the skb queue map actually matches the tx queue used by the driver for the frame.

* ath9k: enable the baseband watchdog events for AR9003Luis R. Rodriguez2010-06-02
| | | | | | | | | | | | | | | | | This enables the baseband watchdog events for the AR9003 family on ath9k. Upon an a baseband watchdog interrupt we reset the hardware, this should address corner case conditions where normal operation can stall. Enable ATH_DBG_RESET to be able to review details of the bb watchdog interrupt once it happens. If you're curious how often this happens just grep the debugfs interrupt file.
