* iwlwifi: mvm: send udev event upon firmware error to dump logsEmmanuel Grumbach2014-03-181-0/+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>
* iwlwifi: mvm: BT Coex add support for Co-running blockEmmanuel Grumbach2014-03-111-0/+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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For testing the D3 (WoWLAN) firmware, it is useful to be able to run the firmware with instrumentation while the host isn't sleeping and can poke at the firmware debug logging etc. Implement this by a debugfs file. When the file is opened the D3 firmware is loaded and all regular commands are blocked. While the file is being read, poll the firmware's PME status flag and report EOF once it changes to non-zero. When it is closed, do (most of) the resume processing. This lets a user just "cat" the file. Pressing Ctrl-C to kill the cat process will resume the firwmare as though the platform resumed for non-wireless reason and when the firmware wants to wake up reading from the file automatically completes. Unlike in real suspend, only disable interrupts and don't reset the TX/RX hardware while in the test mode. This is a workaround for some interrupt problems that happen only when the PCIe link isn't fully reset (presumably by changing the PCI config space registers which the core PCI code does.) Note that while regular operations are blocked from sending commands to the firmware, they could still be made and cause strange mac80211 issues. Therefore, while using this testing feature you need to be careful to not try to disconnect, roam or similar, and will see warnings for such attempts. Als note that this requires an upcoming firmware change to tell the driver the location of the PME status flag in SRAM. D3 test will fail if the firmware doesn't report the pointer.
