2014-03-24ath10k: add soft/hard firmware crash option to simulate_fw_crashMarek Puzyniak
Command WMI_FORCE_FW_HANG_CMDID is not supported in firmware 10.1. In order to have firmware crash simulation functionality also in firmware 10.1 driver can force firmware crash by performing not allowed operation. Driver can deliberately crash firmware when setting vdev param for vdev id out of range. This patch introduces two keywords to simulate_fw_crash: 'soft' which will cause firmware crash that is recoverable by warm firmware reset but supported only in main firmware. 'hard' which will cause firmware crash recoverable by cold firmware reset, this option works for both firmwares. Commands to trigger firmware soft/hard crash: echo 'soft' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash echo 'hard' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash kvalo: remove '\n' before checking the command and simplify how buf is null terminated Signed-off-by: Marek Puzyniak <marek.puzyniak@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-20brcmfmac: reinit watchdog completion after handling watchdogArend van Spriel
The watchdog thread waits on completion that is set from a timer. As the completion is count based this could mean that on a busy system the watchdog is handled multiple times with a very short interval. This is not the intended behaviour. After handling the watchdog it should wait for the next timer expiry. This is accomplished by reinitializing the completion.

2014-03-18iwlwifi: mvm: configure low latency dependent scan parametersAlexander Bondar
In case of system low latency configure passive scan to be fragmented. Set the following scan parameters for both immediate and scheduled scan: - passive scan fragment duration = 20ms - out-of-channel time = 70ms - suspend time = 105ms Restructure channel's active/passive dwell time configuration to better suit the above change. The idea is that under low latency traffic passive scan is fragmented, i.e. that dwell on a particular channel will be fragmented. Each fragment dwell time is 20ms and fragments period is 105ms. Skipping to next channel will be delayed by the same period (105ms). So suspend_time parameter describing both fragments and channels skipping periods is set to 105ms. This value is chosen so that overall passive scan duration will not be too long. Max_out_time in this case is set to 70ms, so for active scanning operating channel will be left for 70ms while for passive still for 20ms (fragment dwell).

2014-03-18iwlwifi: mvm: restructure scan parameters calculationAlexander Bondar
Some scan parameters should be dependent on traffic conditions. Centralize conditions verification in one function and obtain scan max out-of-channel and suspend time in that new function. Rely on bound interfaces indication instead of association state to calculate scan parameters. If no bound interfaces use default values for out-of-channel and suspend time parameters. Additionally, get rid of NL80211_SCAN_FLAG_LOW_PRIORITY checks since no use case for this exists so far.

2014-03-18iwlwifi: mvm: send udev event upon firmware error to dump logsEmmanuel Grumbach
When the firmware asserts, the driver will dump the firmware state to an internal buffer. This buffer is kept aside until it is dumped through debugfs. Once an external application fetched the data, the buffer is freed and a new buffer can be allocated in case another assert occurs. A udev event is sent to trigger an external application. A simple rule like: DRIVER=="iwlwifi", ACTION=="change", RUN+="/sbin/dump_sram.sh" can fetch the data from debugfs. Here is my dump_sram.sh: phyname=$(basename ${DEVPATH}) date=$(date +%F_%H_%M) filename=/var/log/iwl-sram-${phyname}-${date}.bin cat /sys/kernel/debug/ieee80211/${phyname}/iwlwifi/iwlmvm/fw_error_dump > ${filename} The current SRAM size is 80KB so, currently: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin -rw-r--r-- 1 emmanuel emmanuel 81K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin and after compression: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin.xz -rw-r--r-- 1 emmanuel emmanuel 13K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin.xz Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2014-03-17wil6210: fix race between disconnect and Tx NAPIVladimir Kondratiev
When disconnecting some CID, corresponded Tx vring get released. During vring release, all descriptors get freed. It is possible that Tx NAPI working on the same vring simultaneously. If it happens, descriptor may be double freed. To protect from the race above, make sure NAPI won't process the same vring. Introduce 'enabled' flag in the struct vring_tx_data. Proceed with Tx NAPI only if 'enabled' flag set. Prior to Tx vring release, clear this flag and make sure NAPI get synchronized. NAPI enablement status protected by wil->mutex, add protection where it was missing and check for it. During reset, disconnect all peers first, then proceed with the Rx vring.
