2015-03-13ath5k: fix reset raceSergey Ryazanov
To prepare for reset ath5k should finish all asynchronous tasks. At first, it disables the interrupt generation, then it waits for the interrupt handler and tasklets completion, and then proceeds to the HW configuration update. But it does not consider that the interrupt handler or tasklet re-enables the interrupt generation. And we fall in a situation when ath5k assumes that interrupts are disabled, but it is not. This can lead to different consequences, such as reception of the frame, when we do not expect it. Under certain circumstances, this can lead to the following warning: WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]() invalid hw_rix: 1a [..] Call Trace: [<802656a8>] show_stack+0x48/0x70 [<802dd92c>] warn_slowpath_common+0x88/0xbc [<802dd98c>] warn_slowpath_fmt+0x2c/0x38 [<81b51be8>] ath5k_tasklet_rx+0x318/0x6ec [ath5k] [<8028ac64>] tasklet_action+0x8c/0xf0 [<80075804>] __do_softirq+0x180/0x32c [<80196ce8>] irq_exit+0x54/0x70 [<80041848>] ret_from_irq+0x0/0x4 [<80182fdc>] ioread32+0x4/0xc [<81b4c42c>] ath5k_hw_set_sleep_clock+0x2ec/0x474 [ath5k] [<81b4cf28>] ath5k_hw_reset+0x50/0xeb8 [ath5k] [<81b50900>] ath5k_reset+0xd4/0x310 [ath5k] [<81b557e8>] ath5k_config+0x4c/0x104 [ath5k] [<80d01770>] ieee80211_hw_config+0x2f4/0x35c [mac80211] [<80d09aa8>] ieee80211_scan_work+0x2e4/0x414 [mac80211] [<8022c3f4>] process_one_work+0x28c/0x400 [<802df8f8>] worker_thread+0x258/0x3c0 [<801b5710>] kthread+0xe0/0xec [<800418a8>] ret_from_kernel_thread+0x14/0x1c Fix this issue by adding a new status flag, which forbids to re-enable the interrupt generation until the HW configuration is completed.

2015-03-13ath5k: channel change fixSergey Ryazanov
ath5k updates the channel pointer and after that it stops the Rx logic and apply channel to HW. In case of channel switch, such sequence creates a small window when a frame, which is received on the old channel is considered as a frame received on the new one. The most notable consequence of this situation occurs during the switch from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received with CCK rate, e.g. beacon received at the 1mbps, causes the following warning: WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]() invalid hw_rix: 1a [..] Call Trace: [<802656a8>] show_stack+0x48/0x70 [<802dd92c>] warn_slowpath_common+0x88/0xbc [<802dd98c>] warn_slowpath_fmt+0x2c/0x38 [<81b51be8>] ath5k_tasklet_rx+0x318/0x6ec [ath5k] [<8028ac64>] tasklet_action+0x8c/0xf0 [<80075804>] __do_softirq+0x180/0x32c [<80196ce8>] irq_exit+0x54/0x70 [<80041848>] ret_from_irq+0x0/0x4 [<80182fdc>] ioread32+0x4/0xc [<81b4c42c>] ath5k_hw_set_sleep_clock+0x2ec/0x474 [ath5k] [<81b4cf28>] ath5k_hw_reset+0x50/0xeb8 [ath5k] [<81b50900>] ath5k_reset+0xd4/0x310 [ath5k] [<81b557e8>] ath5k_config+0x4c/0x104 [ath5k] [<80d01770>] ieee80211_hw_config+0x2f4/0x35c [mac80211] [<80d09aa8>] ieee80211_scan_work+0x2e4/0x414 [mac80211] [<8022c3f4>] process_one_work+0x28c/0x400 [<802df8f8>] worker_thread+0x258/0x3c0 [<801b5710>] kthread+0xe0/0xec [<800418a8>] ret_from_kernel_thread+0x14/0x1c The easiest way to reproduce this warning is to run scan with dualband NIC in noisy environments, when the channel 11 runs multiple APs. In my tests if the APs num >= 12, the warning appears in the first few seconds of scanning. In order to fix this, the Rx disable code moved to a higher level and placed before the channel pointer update. This is also makes the code a bit more symmetrical, since we disable and enable the Rx in the same function. In fact, at the pointer update time new frames should not appear, because interrupt generation at this point should already be disabled. The next patch should address this issue.

As currently written, macb always ends up requesting a new tx_clk frequency in macb_handle_link_change.

2015-03-12iwlwifi: mvm: BT Coex - update the new APIEmmanuel Grumbach
The firmware was not using the new API, so we don't need to differentiate between the different stages of this new API. The main difference here is that most of the hard coded values are not sent through the command anymore. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: mvm: fix force NMI for 8000Emmanuel Grumbach
The newer devices will enable a new register for this (DEVICE_SET_NMI_8000B_REG), but the interrupt handler isn't wired yet. Keep the old register for now. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: mvm: freeze the non-shared queues when a station goes to sleepEmmanuel Grumbach
When a station goes to sleep, we can't transmit any frame to it. This means that until that station will wake up, a queue that is dedicated to this station won't progress at all. Take this into account when monitoring stuck queues and don't account for the time the station was asleep. This allows to mask false positives where the queues are stuck not because of a bug, but because of the station being asleep. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
