2010-09-21ath5k: Add tx queue configuration functionBruno Randolf
Add the mac80211 callback function to configure the tx queue properties like cw_min, cw_max and aifs. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-09-21ath5k: Simplify cw_min/max and AIFS configurationBruno Randolf
Get rid of overly complicated cw_min/max and AIFS configuration: * Validate values in ath5k_hw_set_tx_queueprops(), so we can use them directly without further checks or computation in ath5k_hw_reset_tx_queue(). * Simplifiy by using AR5K_TUNE_AIFS|CWMIN|CWMAX variables directly since we don't support XR or B channels. That way we can also remove AR5K_TXQ_USEDEFAULT and the confusing logic around it. * Update data types: AIFS is u8, CW's are u16. * Remove now unneeded variables in ath5k_hw.

2010-09-21ath5k: Keep last descriptor in queueBruno Randolf
If we return a TX descriptor to the pool of available descriptors, while a queues TXDP still points to it we could potentially run into all sorts of troube. It has been suggested that there is hardware which can set the descriptors done bit before it reads ds_link and moves on to the next descriptor. While the documentation says this is not true for newer chipsets (the descriptor contents are copied to some internal memory), we don't know about older hardware. To be safe, we always keep the last descriptor in the queue, and avoid dangling TXDP pointers. Unfortunately this does not fully resolve the problem - queues still get stuck! This is similar to what ath9k does. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-09-21ath5k: Add watchdog for stuck TX queuesBruno Randolf
Since we do not know any better solution to the problem that TX queues can get stuck, this adds a timer-based watchdog, which will check for stuck queues and reset the hardware if necessary.

2010-09-21ath5k: Fix TX queues stoppingBruno Randolf
It does not make sense to stop queues for NF calibration. This will not stop transmissions from the card, if there are queued packets.

2010-09-21ath5k: Use four hardware queuesBruno Randolf
Prepare ath5k for WME by using four hardware queues. The way we set up our queues matches the mac80211 queue priority 1:1, so we don't have to do any mapping for queue numbers. Every queue uses 50 of the total 200 available transmit buffers, so the DMA memory usage does not increase with this patch, but it might be good to fine-tune the number of buffers per queue later (depending on the CPU speed and load, and the speed of the medium access, it might not be big enough).

2010-09-16ath9k: fix enabling ANI / tx monitor after bg scanLuis R. Rodriguez
ath9k's entire logic with SC_OP_SCANNING is incorrect due to the way mac80211 currently implements the scan complete callback and we handle it in ath9k. This patch removes the flag completely in preference for the SC_OP_OFFCHANNEL which is really what we wanted. The scanning flag was used to ensure we reset ANI to the old values when we go back to the home channel, but if we are offchannel we use some defaults. The flag was also used to re-enable the TX monitor. Without this patch we simply never re-enabled ANI and the TX monitor after going offchannel. This means that after one background scan we are prone to noise issues and if we had a TX hang we would not recover. To get this to work properly we must enable ANI after we have configured the beacon timers, otherwise hardware acts really oddly. This patch has stable fixes which apply down to [2.6.36+], there *may* be a to fix this on older kernels but requires a bit of work since this patch relies on the new mac80211 flag IEEE80211_CONF_OFFCHANNEL which was introduced as of 2.6.36.

2010-09-16ath9k: fix regression on beacon loss after bgscanLuis R. Rodriguez
When we return to the home channel we were never reseting our beacon timers, this was casued by the fact that the scanning flag was still on even after we returned to our home channel. There are also other reasons why we would get a reset and if we are not off channel we always need to resynch our beacon timers, because a reset will clear them. This bug is a regression introduced on 2.6.36. The order of the changes are as follows: 5ee08656 - Sat Jul 31 - ath9k: prevent calibration during off-channel activity a0daa0e7 - Tue Jul 27 - Revert "mac80211: fix sw scan bracketing" 543708be - Fri Jun 18 - mac80211: fix sw scan bracketing mcgrof@tux ~/linux-2.6-allstable (git::master)$ git describe \ --contains 5ee0865615f65f84e6ee9174771a6716c29e08e1 v2.6.36-rc1~43^2~34^2~22 mcgrof@tux ~/linux-2.6-allstable (git::master)$ git describe \ --contains a0daa0e7592ada797d6835f11529097aabc27ad2 v2.6.36-rc1~571^2~64^2~13 mcgrof@tux ~/linux-2.6-allstable (git::master)$ git describe \ --contains 543708be320d7df692d24b349ca01a947b340764 v2.6.36-rc1~571^2~107^2~187 So 5ee08656 would have worked if a0daa0e7 was not committed but it was so this means 5ee08656 was broken since it assumed that when we were in the channel change routine the scan flag would be lifted. As it turns out the scan flag will be set when we are already on the home channel. For more details refer to: http://code.google.com/p/chromium-os/issues/detail?id=5715 These issues will need to be considered for our solution on reshifting the scan complete callback location on mac80211 on current development kernel work.

2010-09-16ath9k: fix power save race conditionsLuis R. Rodriguez
ath9k has a race on putting the chip into network sleep and having registers read from hardware. The race occurs because although ath9k_ps_restore() locks its own callers it makes use of some variables which get altered in the driver at different code paths. The variables are the ps_enabled and ps_flags. This is easily reprodicible in large network environments when roaming with the wpa_supplicant simple bgscan. You'd get some 0xdeadbeef read out on certain registers such as: ath: timeout (100000 us) on reg 0x806c: 0xdeadbeef & 0x01f00000 != 0x00000000 ath: RX failed to go idle in 10 ms RXSM=0xdeadbeef ath: timeout (100000 us) on reg 0x7000: 0xdeadbeef & 0x00000003 != 0x00000000 ath: Chip reset failed The fix is to protect the ath9k_config(hw, IEEE80211_CONF_CHANGE_PS) calls with a spin_lock_irqsave() which will disable contendors for these variables from interrupt context, timers, re-entry from mac80211 on the same callback, and most importantly from ath9k_ps_restore() which is the only call which will put the device into network sleep.

2010-09-16ath9k_htc: Fix register read through bulk pipeRajkumar Manoharan
To optimize register read/write operations, the HTC firmwares were patched to change EP3 and EP4 pipe types from Interrupt to Bulk. So register writes are submitted as bulk urbs, but register reads are not. Also changing the register read endpoint pipe as bulk type when URBs are filled improves the register reads considerably which results in reduced scan time and CPU utilization.

2010-09-16ath5k: Use common ath key management functionsBruno Randolf
Use common ath key management functions in ath5k. This fixes problems with HW encryption in AP mode, which was broken in the ath5k implementation. Before (with the ath5k implementation) only one client could connect to the AP using HW encryption and WPA. When a second client connected, the first client was not able to send/receive any more packets. Because of the problems with HW encryption, software encryption was always used in AP mode, which resulted in a high CPU load (and/or low thruput) on embedded devices. Instead of trying to fix the implementation in ath5k it makes more sense to share the code with ath9k. This also enables HW encryption for AP mode again.

2010-09-16ath: Copy key cache management functions from ath9k to athBruno Randolf
Copied the key cache management functions from ath9k (common.c and hw.c) to ath/key.c so we can use them from ath5k, later. Minor changes have been made: - renamed ath9k_* to ath_* - replaced ah->caps.keycache_size with common->keymax - removed ATH9K_IS_MIC_ENABLED since it is always true. - the AR_PCU_MIC_NEW_LOC_ENA flag is replaced with (splitmic == 0).
