      ath10k: DFS Host Confirmation · 6f6eb1bc
      由 Sriram R 提交于 
      In the 10.4-3.6 firmware branch there's a new DFS Host confirmation
feature which is advertised using WMI_SERVICE_HOST_DFS_CHECK_SUPPORT flag.

This new features enables the ath10k host to send information to the
firmware on the specifications of detected radar type. This allows the
firmware to validate if the host's radar pattern detector unit is
operational and check if the radar information shared by host matches
the radar pulses sent as phy error events from firmware. If the check
fails the firmware won't allow use of DFS channels on AP mode when using
FCC regulatory region.

Hence this patch is mandatory when using a firmware from 10.4-3.6 branch.
Else, DFS channels on FCC regions cannot be used.

      ath10k: debugfs support to get final TPC stats for 10.4 variants · bc64d052
      由 Maharaja Kennadyrajan 提交于 
      Export the final Transmit Power Control (TPC) value, which is the
minimum of control power and existing TPC value to user space via
a new debugfs file "tpc_stats_final" to help with debugging.
It works with the new wmi cmd and event introduced in 10.4 firmware
branch.

      ath10k: dma unmap mgmt tx buffer if wmi cmd send fails · 38a1390e
      由 Rakesh Pillai 提交于 
      WCN3990 sends mgmt frames by reference via WMI.
The host dma maps the mgmt frame and sends the physical
address to the firmware in the wmi command. Since the
dma mapping is done in the gen_mgmt_tx and if the wmi
command send fails, the corresponding mgmt frame is
not being dma unmapped.

Fix the missing dma unmapping of mgmt tx frame when
wmi command sending fails for mgmt tx by reference
via WMI. The already exisiting mgmt tx using copy by
value does not need such dma unmapping.
Add a separate wmi-tlv op for mgmt tx via ref, which
takes care of unmapping the dma address, in case of
wmi command sending failure.

      由 Michal Kazior 提交于 
      WMI ops wrappers did not properly check for null
function pointers for spectral scan. This caused
null dereference crash with WMI-TLV based firmware

The crash could be triggered with:

  ip link set dev wlan0 up
  echo background > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl

The crash looked like this:

      ath10k: enable adaptive CCA · 62f77f09
      由 Maharaja 提交于 
      European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.

Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.

The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

      ath10k: refactor phyerr event handlers · 991adf71
      由 Raja Mani 提交于 
      Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. 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.
