ath9k tries to prevent WMM queue tx buffer starvation caused by traffic on different queues by limiting the number of pending frames in a tx queue (tracked in the ath_buf structure). This had a leak issue, because the a skb can be reassigned to a different ath_buf in the tx path, causing the pending frame counter to become inaccurate. To fix this, track the number of frames in an array in the softc, using the mac80211 queue mapping as index. Signed-off-by:

AR5416 and all newer chipsets use a 32 bit rx timestamp, so there is no need to keep the 15 bit timestamp extending logic around. This patch removes ath9k_hw_extend_tsf (replaced by a call to ath9k_hw_gettsf64), and reduces the frequency of TSF reads, which can improve performance in some cases. This change also has the side effect of making rx timestamps more accurate. Signed-off-by:

ath_get_mac80211_qnum() expects the queue 'subtype' (internal ID for the WMM AC) as argument when looking up the mac80211 queue, however ath_wake_mac80211_queue provides txq->axq_qnum instead, which contains the hardware queue number. Fix this by keeping track of the WMM class ID in the txq data structure. Signed-off-by:

AR9003 has been tested with the new ANI implementation and so ANI can now be enabled for that family. Signed-off-by:

Luis R. Rodriguez authored
This adds support for ANI for AR9003. The implementation for ANI for AR9003 is slightly different than the one used for the older chipset families. It can technically be used for the older families as well but this is not yet fully tested so we only enable the new ANI for the AR5008, AR9001 and AR9002 families with a module parameter, force_new_ani. The old ANI implementation is left intact. Details of the new ANI implemention: * ANI adjustment logic is now table driven so that each ANI level setting is parameterized. This makes adjustments much more deterministic than the old procedure based logic and allows adjustments to be made incrementally to several parameters per level. * ANI register settings are now relative to INI values; so ANI param zero level == INI value. Appropriate floor and ceiling values are obeyed when adjustments are combined with INI values. * ANI processing is done once per second rather that every 100ms. The poll interval is now a set upon hardware initialization and can be picked up by the core driver. * OFDM error and CCK error processing are made in a round robin fashion rather than allowing all OFDM adjustments to be made before CCK adjustments. * ANI adjusts MRC CCK off in the presence of high CCK errors * When adjusting spur immunity (SI) and OFDM weak signal detection, ANI now sets register values for the extension channel too * When adjusting FIR step (ST), ANI now sets register for FIR step low too * FIR step adjustments now allow for an extra level of immunity for extremely noisy environments * The old Noise immunity setting (NI), which changes coarse low, size desired, etc have been removed. Changing these settings could affect up RIFS RX as well. * CCK weak signal adjustment is no longer used * ANI no longer enables phy error interrupts; in all cases phy hw counting registers are used instead * The phy error count (overflow) interrupts are also no longer used for ANI adjustments. All ANI adjustments are made via the polling routine and no adjustments are possible in the ISR context anymore * A history settings buffer is now correctly used for each channel; channel settings are initialized with the defaults but later changes are restored when returning back to that channel * When scanning, ANI is disabled settings are returned to (INI) defaults. * OFDM phy error thresholds are now 400 & 1000 (errors/second units) for low/high water marks, providing increased stability/hysteresis when changing levels. * Similarly CCK phy error thresholds are now 300 & 600 (errors/second) Signed-off-by: -

The new ANI implementation will use this to skip ANI calibration upon a scan. This cannot be ported to the older ANI implementation unless default ANI values from the ANI are also used upon a scan. This is essentially what one of the things thenew ANI does. Signed-off-by:

The AR9003 hardware family will use a slightly modified ANI implementation which has not yet been tested on the other hardware families. To allow for this new ANI implementation a few ANI calls need to be abstracted away. This patch just allows for each hardware family to declare their own ANI ops and annotates the current ANI implementation as old. Signed-off-by:

We get an MIB interrupt when we hit certain PHY error counter thresholds. If ANI is disabled but the MIB interrupt is enabled we'll keep around the old MIB interrupt causes. Since ath9k disables the MIB interrupt when ANI is disabled this is not a fix, but more of a sanity fix in case we ever need the MIB interrupt enabled but disabling ANI. Signed-off-by:

The clock rate was assumed to be static but it actually changes depending on the mode of operation, correct this to help improve the calcuation of the listenTime for ANI. This change will help adjust ANI more accurately on different PHY thresholds. Signed-off-by:

Currently, driver tracing is sometimes invoked after and sometimes before the actual driver callback. This is fine as long as the driver has no tracing itself, but as soon as it does it gets confusing. To make traces containing such information easier to read, introduce a return tracer in mac80211 that essentially brackets any driver tracing, and invoke the real trace before the driver's callback, only showing the return value, if any, afterwards. Since tracing records the process, there's no problem with overlapping calls if that should happen. Signed-off-by:

The recent change to processing action frames from the management frame queue had already broken action frame accounting, and my rework didn't help either. So add back accounting and simplify the code with a label rather than duplicating it, and also add accounting for management frames. Signed-off-by:

Allow drivers to sleep, and indicate this in the documentation. ath9k has some locking I don't understand, so keep it safe and disable BHs in it, all other drivers look fine with the context change. Signed-off-by:

To prepare for allowing drivers to sleep in ampdu_action, change the locking in the TX aggregation code to use the mutex the RX part already uses. The spinlock is still necessary around some code to avoid races with TX, but now we can also synchronize_net() to avoid getting an inconsistent sequence number. Signed-off-by:

Johannes Berg authored
Since we want the code to be able to sleep in the future, it must not be called from the timer directly. To achieve that, simply call the function drivers would call, and also use RCU in the timer to get the struct so we don't need to rely on the spinlock in the future. Signed-off-by:
