| | | | | | | | | | | | | | | | | | All of the survey data is (currently) per channel anyway, so having the word "channel" in the name does nothing. In the next patch I'll introduce global data to the survey, where the word "channel" is actually confusing. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | ath10k: add thermal sensor device supportRajkumar Manoharan2014-12-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Temperature sensor generates electrical analog voltage from temperature of each chain. The analog voltage is converted to digital value through ADC. For reading temperature values fom user space, hw monitoring device is used. Whenever the user requests for current temperature, the driver sends WMI command and wait for response.

| | | | | | | | | | | | | | | | | | | | | | | | | | 10.2.4 firmware uses bitmask in wmi_resource_config to configure 10.2 firmware features like airtime fairness and rx batch mode instead of maintaining separete bool entry. This allows new features that can be configure during init time without breaking backward compatibility. kvalo: use WMI op version, bump up FW API to 4 to not break older versions of ath10k Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new wmi interface controls noise floor (NF) calibration period via debugfs as firmware has introduced it on v10.2. It allows users to modify frequency of NF calibration in millisecond and changes RSSI reporting frequency consequently. Short calibration period will trigger more frequent NF calibration, so that RSSI reported in receive frames is more realistic. Till now calibration was done at 30 seconds.

| | | | | | | | | | | | | | | | | | | | | | | | Latest main firmware branch introduced a new WMI ABI called wmi-tlv. It is not a tlv strictly speaking but something that resembles it because it is ordered and may have duplicate id entries. This prepares ath10k to support new hw.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the 10.x fw branch support was introduced it became apparent ath10k will need to be able to deal with different fw ABIs eventually. The patch creates an abstraction for dealing with command and event structures across different ABIs and mostly gets rid of the ATH10K_FW_FEATURE_WMI_10X flag usage.

* ath10k: fix station count enforcementMichal Kazior2014-11-261-1/+1
| | | | | | | | | | | | | | | The number of peers isn't directly translatable to the number of stations because ath10k needs to reserve a few extra peers for special cases like multi-vif concurrency. The previous limit was 126 and 15 stations in AP mode for 10.x and main firmware branches respectively. The limit is now 128 and 16 which was the original intention.

* ath10k: fix shared WEPSujith Manoharan2014-11-261-0/+36
| | | | | | | | | | | | | | | | | When static keys are used in shared WEP, when a station is associated, message 3 is sent with an encrypted payload. But, for subsequent authentications that are triggered without a deauth, the auth frame is decrypted by the HW. To handle this, check if the WEP keys have already been set for the peer and if so, mark the frame as decrypted. This scenario can happen when a station changes its default TX key and initiates a new authentication sequence.

* ath10k: speed up hw recoveryMichal Kazior2014-10-311-1/+4
| | | | | | | | | | | | | | | | | | In some cases hw recovery was taking an absurdly long time due to ath10k waiting for things that would never really complete. Instead of waiting for inevitable timeouts poke all completions and wakequeues and check if it's still worth waiting. Reading/writing ar->state requires conf_mutex. Since waiters might be holding it introduce a new flag CRASH_FLUSH so it's possible to tell waiters to abort whatever they were waiting for.

| | | | | | | | | | | | | | | | If stat data exceeds wmi-htc buffer limits firmware splits it into many wmi stats update events which are delivered in a ping-pong fashion triggered by wmi stats request command.

| | | | | | | | | | | | | | | The logic responsible for processing the event is no different across different firmware binaries.

* ath10k: workaround fw beaconing bugMichal Kazior2014-09-231-14/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some firmware revisions don't wait for beacon tx completion before sending another SWBA event. This could lead to hardware using old (freed) beacon data in some cases, e.g. tx credit starvation combined with missed TBTT. This is very very rare. On non-IOMMU-enabled hosts this could be a possible security issue because hw could beacon some random data on the air. On IOMMU-enabled hosts DMAR faults would occur in most cases and target device would crash. Since there are no beacon tx completions (implicit nor explicit) propagated to host the only workaround for this is to allocate a DMA-coherent buffer for a lifetime of a vif and use it for all beacon tx commands. Worst case for this approach is some beacons may become corrupted, e.g. garbled IEs or out-of-date TIM bitmap. Keep the original beacon-related code as-is in case future firmware revisions solve this problem so that the old path can be easily re-enabled with a fw_feature flag.

| | | | | | | | | | | | | | | | | | | This aims at fixing some rare scan bugs related to firmware reporting unexpected scan event sequences. One such bug was if spectral scan phyerr reporting prevented firmware from properly propagating scan events to host. This led to scan timeout. After that next scan would trigger scan completed event first (before scan started event) leading to ar->scan.in_progress and timeout timer states to be overwritten incorrectly and making the very next scan to hang forever.
