2014-09-03iwlwifi: mvm: reset the temperature when temperature test is disabledLuciano Coelho1-0/+10
Since we can't read the actual temperature when the firmware is running, just set the temperature to 0 when the test is disabled and disable CT Kill if it was enabled. Additionally, since we rely on iwl_mvm_tt_handler() to exit CT kill when in test mode, call iwl_mvm_exit_ctkill() in that function if the temperature is low again. Also make the iwl_mvm_enter_ctkill() and iwl_mvm_exit_ctkill() return if called when not necessary anymore (e.g. when iwl_mvm_exit_ctkill() is called when we're not in CT-kill).

Add iwl_mvm_ref_sync() calls (with new ref types) to flows that might access the device directly. These calls make sure the device is out of d0i3, and the bus is available for direct access.

2014-03-18iwlwifi: mvm: send udev event upon firmware error to dump logsEmmanuel Grumbach1-0/+53
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>
2014-03-11iwlwifi: mvm: BT Coex add support for Co-running blockEmmanuel Grumbach1-0/+3
7265 features a new calibration which is called antenna coupling. The purpose of this calibration (which isn't really a calibration), is to measure the isolation between the antennas and that can give us useful information for the Coex modules. With this information, we can tune the LookUpTables (LUTs) that define the BT / WiFi contention policy. The LUTs currently contain dummy values - but they will be updated soon. While at it, change the current code to stop duplicate the host command while sending. This was needed back then, when the command was short enough to be allocated on the stack. Since then, the command grew a lot and is now allocated on the heap - hence we can use the NOCOPY option instead. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
