* ath9k: Fix BTCOEX timer triggering comparisionMohammed Shafi Shajakhan2012-09-112-2/+7
| | | | | | | | | | | | Its more correct to convert btcoex_period to 'us' while comparing with btcoex_no_stomp which is in 'us'. Did not find any functionality issues being fixed, as the generic hardware timer triggers are usually refreshed with the newer duty cycle.

* ath9k_hw: Fix invalid MCI GPM index access/cachingMohammed Shafi Shajakhan2012-09-111-0/+8
| | | | | | | | | | | There is a possibility that AR_MCI_GPM_1 register can return 0xdeadbeef and this results in caching of invalid GPM index in ar9003_mci_is_gpm_valid. Ensure we have appropriate checks to avoid this. Cc: xijin luo <xijin@qca.qualcomm.com> Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

| * ath9k: Fix a crash in 2 WIRE btcoex chipsetsMohammed Shafi Shajakhan2012-09-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generic timers for BTCOEX functionality is applicable only for 3 WIRE BTCOEX (and MCI) chipsets. Hence btcoex->no_stomp_timer is allocated only 3 WIRE btcoex chipsets and in all the other cases its NULL. Make sure we stop the generic timer only if 'btcoex->hw_timer_enabled' is true(only if its up and running) Fixes the following crash [68757.020454] BUG: unable to handle kernel NULL pointer dereference at 0000000c [68757.020916] IP: [<f9b055c3>] ath9k_hw_gen_timer_stop+0x13/0x80 [ath9k_hw] [68757.021251] *pde = 00000000 [68757.024384] EIP: 0060:[<f9b055c3>] EFLAGS: 00010082 CPU: 0 [68757.024384] EIP is at ath9k_hw_gen_timer_stop+0x13/0x80 [ath9k_hw] [68757.024384] EAX: d32d0000 EBX: d32d0000 ECX: 00000000 EDX: 00000000 [68757.024384] ESI: e67c24c0 EDI: 00000296 EBP: e137be2c ESP: e137be20 [68757.024384] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [68757.024384] CR0: 8005003b CR2: 0000000c CR3: 00b99000 CR4: 000407d0 [68757.024384] DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 [68757.024384] DR6: ffff0ff0 DR7: 00000400 [68757.024384] Process kworker/u:2 (pid: 8917, ti=e137a000 task=ea7a6860 task.ti=e137a000) [68757.024384] Stack: [68757.024384] c06c4676 d32d0000 e67c24c0 e137be38 f81c9590 e67c1ca0 e137be40 f81c95d9 [68757.024384] e137be64 f81cd1c5 00000246 00000002 d32d0000 e67c05e0 e67c1ca0 e67c05e0 [68757.024384] 00000000 e137beac f81cdfa0 e137be84 00000246 00000246 e67c1ca0 e67c1ca0 [68757.024384] Call Trace: [68757.024384] [<c06c4676>] ? _raw_spin_lock_irqsave+0x86/0xa0 [68757.024384] [<f81c9590>] ath9k_gen_timer_stop+0x10/0x40 [ath9k] [68757.024384] [<f81c95d9>] ath9k_btcoex_stop_gen_timer+0x19/0x20 [ath9k] [68757.024384] [<f81cd1c5>] ath9k_ps_restore+0x85/0x110 [ath9k] [68757.024384] [<f81cdfa0>] ath9k_config+0x220/0x520 [ath9k] [68757.024384] [<f81cd47d>] ? ath9k_flush+0x15d/0x1b0 [ath9k] [68757.024384] [<f85c7ca5>] ieee80211_hw_config+0x135/0x2c0 [mac80211] [68757.024384] [<f860e3c8>] ieee80211_dynamic_ps_enable_work+0x198/0x5f0 [mac80211] Cc: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Cc: Bala Shanmugam <bkamatch@qca.qualcomm.com> Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

| * ath9k_hw: enable PA linearizationFelix Fietkau2012-09-051-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature had been disabled in ath9k because the code to support it was incomplete, but now the code is in sync with the internal QCA codebase, so it's time to enable it. On many newer devices, the calibration is assumed to be done with PA linearization enabled. Tests with a particular AR933x device showed that the signal emitted at full power was highly distorted and unreliable with PA linearization disabled. With this patch, the signal becomes clear and stability is improved. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * ath9k: fix decrypt_error initialization in ath_rx_tasklet()Lorenzo Bianconi2012-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath_rx_tasklet() calls ath9k_rx_skb_preprocess() and ath9k_rx_skb_postprocess() in a loop over the received frames. The decrypt_error flag is initialized to false just outside ath_rx_tasklet() loop. ath9k_rx_accept(), called by ath9k_rx_skb_preprocess(), only sets decrypt_error to true and never to false. Then ath_rx_tasklet() calls ath9k_rx_skb_postprocess() and passes decrypt_error to it. So, after a decryption error, in ath9k_rx_skb_postprocess(), we can have a leftover value from another processed frame. In that case, the frame will not be marked with RX_FLAG_DECRYPTED even if it is decrypted correctly. When using CCMP encryption this issue can lead to connection stuck because of CCMP PN corruption and a waste of CPU time since mac80211 tries to decrypt an already deciphered frame with ieee80211_aes_ccm_decrypt. Fix the issue initializing decrypt_error flag at the begging of the ath_rx_tasklet() loop.

| * ath9k: fix interrupt storms on queued hardware resetFelix Fietkau2012-08-103-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b74713d04effbacd3d126ce94cec18742187b6ce "ath9k: Handle fatal interrupts properly" introduced a race condition, where IRQs are being left enabled, however the irq handler returns IRQ_HANDLED while the reset is still queued without addressing the IRQ cause. This leads to an IRQ storm that prevents the system from even getting to the reset code. Fix this by disabling IRQs in the handler without touching intr_ref_cnt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AR1111 is same as AR9485. The h/w difference between them is quite insignificant, Felix suggests only very few baseband features may not be available in AR1111. The h/w code for AR9485 is already present, so AR1111 should work fine with the addition of its PID/VID.

* | ath9k: Fix TX filter usageSujith Manoharan2012-09-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TX filter bit for a station would be set by the HW when a frame is not acked. A frame would be completed with ATH9K_TXERR_FILT status only when the corresponding filter bit for the destination station is already set. Currently, un-acknowledged packets are added to the pending queue and retried, but the "clear_dest_mask" bit in the descriptor is set only when the TX status has been ATH9K_TXERR_FILT. This results in packet loss and the log shows: wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746071 wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746076 wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746377 ... ... This issue can be resolved by making sure that the destination mask is cleared when the packet is being retried and the earlier TX status is ATH9K_TXERR_XRETRY.

Suppose there are 4 ath9k-htc usb dongles working, kernel has to consume about 4*50KBytes RAM to cache firmware for all dongles. After applying the patch, kernel only caches one single firmware image in RAM for all ath9k-htc devices just during system suspend/resume cycle. When system is ready for loading firmware, ath9k-htc can request the loading from usersapce. During system resume, ath9k-htc still can load the firmware which was cached in kernel memory before system suspend. Cc: ath9k-devel@lists.ath9k.org Cc: "Luis R.

| | | | | | | | | | | | | | | | | | In the tx_last_beacon() callback, mac80211's beaconing status can be used instead. The beacon tasklet doesn't require it because it is disabled when removing a slot. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * The beaconing status routine is not required, since in multi-VIF cases the HW beacon parameters should not be re-configured. * Remove SC_OP_TSF_RESET - when a beaconing interface comes up the first time, the TSF has to be reset. * Simplify ath9k_allow_beacon_config(). * Handle setting/clearing the SWBA interrupt properly. * Remove the TSF mangling in IBSS mode, it is not required. * General code cleanup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Do not set/clear TSF when adding/deleting an interface. This should be done when the BSS is set up and should also take into account the existence of other interfaces. * Set opmode explicitly. * ANI setup needs to be decided based on multiple interfaces. This can be done via the bss_info_changed() callback. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | This patch revamps interface addition and deletion and simplifies slot allocation. There is no need to setup the beacon buffer in add/remove interface, remove this and use simple APIs for assigning/deleting slots.
