2020-10-01wcn36xx: Advertise beacon filtering support in bmpsLoic Poulain1-0/+2
In bmps mode, beacons are filtered, and firmware is in charge of monitoring the beacons and report changes or loss. mac80211 must be advertised about such change to prevent it's internal timer based beacon monitor to report beacon loss. Fix that by setting/clearing the IEEE80211_VIF_BEACON_FILTER vif flag on bmps entry/exit.

2020-10-01ath11k: start a timer to update TCL HPCarl Huang5-0/+130
The timer is to check if TCL HP isn't updated to target. The timer will postpone itself if there are TX operations during the interval, otherwise the timer handler updates the HP again so the index value in HP register will be forwarded to target register, and the timer stops afterwards.

2020-10-01ath11k: enable shadow register configuration and accessCarl Huang9-8/+194
To enable shadow register access, host needs to pass shadow register configuration to firmware via qmi message. Host also needs to update ring's HP or TP address to shadow register address. The write operation to shadow register will be forwarded to target register by hardware automatically, and the write operation to shadow register is permitted even when the target is in power save or sleep mode. Update the shadow config whenever power up happens. This feature is controlled by hw parameter supports_shadow_regs which is only enabled for QCA6390.

2020-10-01ath11k: read and write registers below unwindowed addressCarl Huang2-0/+42
For QCA6390, host can read and write registers below unwindowed address directly without programming the window register. For registers below bar0 + 4k - 32, host can read and write regardless of the power save state. Shadow registers are located below bar0 + 4K - 32. Before MHI power up, there is no need to wakeup MHI so ini_done is added to indicate it.

2020-10-01ath11k: debugfs: fix crash during rmmodCarl Huang1-4/+4
With QCA6390 when doing rmmod the kernel crashed. The reason was that the destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy() accidentally had swapped the debugfs directories and ath11k_debugfs_soc_destroy() was removing an already removed directory, which crashed the kernel. The source of confusion is badly named function and variable names. I think the best way to clean this up is actually to merge the corresponding functions, but that's for another patch. Let's first just fix the crash.

2020-10-01ath11k: add packet log support for QCA6390Carl Huang9-56/+169
Add packet log support for QCA6390, otherwise the data connection will stall within a minute or so. Enable it via debugfs and use trace-cmd to capture the pktlogs. echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter The mon status ring doesn't support interrupt so far, so host starts a timer to reap this ring. The timer handler also reaps the rxdma_err_dst_ring in case of monitor mode. As QCA6390 requires bss created ahead of starting vdev, so check vdev_start_delay for monitor mode. For QCA6390, it uses wbm_desc_rel_ring to return descriptors. It also uses rx_refill_buf_ring to fill mon buffer instead of rxdma_mon_buf_ring.

2020-10-01iwlwifi: mvm: ignore the scan duration parameterAvraham Stern1-45/+10
The scan request may specify the request scan dwell time. However, this value may not always be optimal (e.g. short dwell time for a passive channel). This may happen in a scan request as a result of beacon report request, in which the AP may request an active scan, thus setting a short dwell time, but the station will perform a passive scan due to regulatory. Ignore the scan duration parameter and always use the internal scan dwell time which should be optimal.

2020-10-01iwlwifi: mvm: Add FTM initiator RTT smoothing logicIlan Peer5-0/+138
The overcome instabilities in the RTT results add smoothing logic to the reported results. In short, the smoothing logic tracks the RTT average of each responder for a period of time, and in case a new RTT results is found to be a spur, the tracked RTT average is reported instead of the current RTT measurement. Smooth logic debug configuration using iwl-dbg-cfg.ini: - MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic (default=0). - MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining the weight of the current RTT results vs. the RTT average tracked based on the previous results. A value of 100 means use only the current RTT results. - MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which the RTT average tracked based on previous results is considered valid. - MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive and below the RTT average by at least this value, report the average RTT instead of the current one. In units of picoseconds. - MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive and above the RTT average by at least this value, report the average RTT instead of the current one. In units of picoseconds.
