2011-08-15ath9k: initialize tx chainmask before testing channel tx power valuesFelix Fietkau
commit c1227340ca65c2069222a956a68b6842d460c4f4 upstream. With an uninitialized chainmask, the per-channel power will only contain the power limits for a single chain instead of the combined tx power.

The DMA latency issue is observed only in Intel pinetrail platforms but in the driver we had a default PM-QOS value of 55.

2011-01-28ath9k: Fix power save usage count imbalance on deinitRajkumar Manoharan
While unloading the driver, the ps_usecount is incremented before configuring gpio registers in deinit_device. But it is failed to restore the ps_usecount after that. The problem is that the chip is forcibly moved to FULL SLEEP by radio_disable when mac80211 is reporting as idle though ps_usecount is not zero. This patch retores ps_usecount properly and ensures that the chip is always moved to full sleep only if ps usage count is zero which also helps in debugging deadbeef on multivif case. And also fixes the following warning. ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:536 ath_stoprecv+0xf4/0x100 [ath9k]() Cc: stable@kernel.org Cc: Paul Stewart <pstew@google.com> Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

2010-12-22ath9k: Reset keycache on resumeMohammed Shafi Shajakhan
It looks like some hardware registers are left into undefined state after suspend/resume. At minimum, this can cause odd issues related to key cache and hardware trying to encrypt/decrypt frames unexpectedly. This seems to happen even when there is no keys configured, i.e., hardware can end up touching TX frames just based of invalid key cache context even if the driver is not asking a specific entry to be used. In addition, RX can likely be affected. This patch fixes this issue.

2010-12-07ath9k: Parse DTIM period from mac80211Mohammed Shafi Shajakhan
With the current save power save implementation we assume a dtim period of 1.This value is assigned based on a sanity check in the driver eventhough we had not parsed it from mac80211.This patch obtains the actual DTIM period from AP by parsing it from mac80211.Yet for handling multicast traffic we may still have it as fixed rather than parsing it from mac80211 .This does not breaks power save or anything as the sleep duration is currently fixed in the driver.This patch may serve to improve power save in the future by using dtim period for sleep duration and using correct dtim period adhoc mode.

2010-11-15ath9k: rework tx queue selection and fix queue stopping/wakingFelix Fietkau
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.

2010-10-15ath9k_hw: remove enum wireless_mode and its usersFelix Fietkau
The wireless mode bitfield was only used to detect 2.4 and 5 GHz support, which can be simplified by using ATH9K_HW_CAP_* capabilities. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-11ath9k: add compile time checking for the size of the channel listFelix Fietkau
This prevents random memory corruption if the number of channels ever gets changed without an update to the internal channel array size. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-05ath9k: add WDS interfaces to ath9kBill Jordan
Enable WDS for the ath9k driver. Signed-off-by: Bill Jordan <bjordan@rajant.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-05ath9k: fix channel flag / regd issues with multiple cardsFelix Fietkau
Since the regulatory code touches the channel array, it needs to be copied for each device instance. That way the original channel array can also be made const. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org [all] Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-10-05ath9k: remove the noise floor value in the ani structFelix Fietkau
common->ani.noise_floor is now only used for a similar redundant debug message similar to the one that was removed from ath9k_htc in an earlier patch. Remove it from ath9k as well now. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
