| | | | | | | | | | | | | | | | | | | | | | | | FW dump may be triggered when running init ucode, for example due to a sysassert. In this case fw_dump_wk may run after mvm is freed, resulting in a kernel panic. Fix it by flushing the work.

| | | | | | | | | | | | | | | | | | | | | | | | | | During the CT-kill exit flow, the card is powered up and partially initialized to check if the temperature is already low enough. Unfortunately the init bails early because the CT-kill flag is set. Make the code bail early only for HW RF-kill, as was intended by the author. CT-kill is self-imposed and is not really RF-kill.

| * iwlwifi: mvm: fix D3 CCMP TX PN assignmentJohannes Berg2015-10-051-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When going into/coming out of D3, the TX PN must be programmed into and restored from the firmware respectively. The restore was broken due to my previous commit to move PN assignment into the driver. Sending the PN to the firmware still worked since we now use the counter that's shared with mac80211, but accessing it through the mac80211 API makes no sense now. Fix this by reading/writing the counter directly. This actually simplifies the code since we don't need to round-trip through the key_seq structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from all drivers"), the code that cleared all interrupt enable bits before setting them was removed for all PCI drivers. This fixed an issue that caused TX to be blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft lockups to occur on boot. For that reason, the portion of the earlier commit that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected. See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where this regression affected user systems. Note that this bug does not appear on any of the developer's setups. For those users whose systems are affected by the TX blockage, but do not lock up on boot, a module parameter is added to disable the interrupt clear Fixes: 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from all drivers") Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> [V4.1+] Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To enable/configure spectral scan parameters in 10.4 firmware, existing wmi spectral related functions can be reused. Link those functions in 10.4 wmi ops table. In addition, adjust bin size (only when size is 68 bytes) before reporting bin samples to user space. The background for this adjustment is that qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte carries band edge detection data (+32) mainly used in radar detection purpose. Additional last 4 bytes are stripped to make bin size valid one. This bin size adjustment will happen only for qca99x0, all other chipsets will report proper bin sizes (64/128) without extra 4 bytes being added at the end. The changes are validated in qca99x0 using 10.4 firmware. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

This is the problem in 10.4 fw specific phyerr event handling where it uses different phyerror header format. Before adding 10.4 specific handler, little bit of refactor is done in existing phyerr handlers. Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and struct wmi_phyerr_ev_arg) are introduced to remove dependency of using firmware specific header format in the code. So that firmware specific phyerror handlers can populate values to abstracted structures and the following code can use abstracted struct for further operation. .pull_phyerr_hdr is added newly to pull common phyerr header info like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr handler is changed and called to parse every sub phyerrs in the event. Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

| | * ath10k: fix invalid survey reporting for QCA99X0Vasanthakumar Thiagarajan2015-08-172-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are three WMI_CHAN_INFO events reported per channel in QCA99X0 firmware. First one is a notification at the begining of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0), second one is a notification at the end of the dwell time with cmd_flag CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for the channel. Since there is a new state before the completion, the handler is to fixed so that the counts are deducted from the ones reported with CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE. Without this fix there will be lots of 0 msecs reported as active and busy time.

| | * ath10k: wake up queue upon vif creationMichal Kazior2015-08-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vif's vdev_id is used as queue number. However due to the tx pausing design in ath10k it was possible for a new interface to be created with its tx queue stopped (via ieee80211_stop_queues). This could in turn leave the interface inoperable until ath10k_mac_tx_unlock() was called. This problem only affected multi-vif scenarios when new interfaces were created some time later after other interfaces have been running for some time and had Tx queue full at some point prior. Possible manifestation of the bug was authentication timeout for a client vif.

This could be reproduced after running a lot of traffic enough to saturate 100% of the driver Tx queue and then trying to send offchannel traffic.

With this patch the nvram load routines will fall back to this method when there is no nvram file and support is available in the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The event mask length is determined by the highest event number that is specified in the driver. When this length is shorter than firmware expects setting event mask will fail and device becomes pretty useless. This issue was reported with bcm4339 firmware that was recently released.
