There are some boot loader versions which perform redundant

while boot loader access memory can cause the device memory
controller to get stuck, the FW will fail to load and the

For such boot loaders implement a workaround where we freeze

in net a fixup for a testcase prohibits logical operations

Add memory dump to the firmware crash data file which is provided to user space
via devcoredump interface. This makes it easier for firmware engineers to debug
firmware crashes.
Due to increased memory consumption the memory dump is disabled by default. To
enable it make sure that bit 3 is set in coredump_mask module parameter:
modprobe ath10k_core coredump_mask=0xffffffff
When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during
device probe. The actual memory layout is different in hardware versions and
the layouts are defined in coredump.c. The memory is split to regions and, to
get even finegrained control of what to copy, the region can split to smaller
sections as not all registers are readable (which could cause the whole system
to stall).

Due to the limitation of wmi tlv parsing logic, if there are

the last value, as it overwrites the prev value of the same tlv tag.
The service ready event in wcn3990 contains two parameters of the

Current hw_scan implementation does not trigger offloaded
hardware scan and seems to only put the device in a kind of
listening mode (beacon/probe-response) for software scan.
Since no probe request are generated by the software, current
scanning method is similar to a passive scan.
This patch introduces support for 'true' hardware offloaded scan.
Hardware scan is configured and started via the start-scan-offload
firmware message. Once scan has been completed a scan indicator
message is received from firmware.
Moreover, this patch includes support for directed probe-request,
allowing connection with hidden APs. It also fixes scan issues with
band-steering AP which are not 'visible' with passive scan (due to
hidden ssid in beacons).
Let's keep the 'legacy' scanning method in case scan-offload is not
supported.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.
The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.
This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.
The device tree requires addition strings to define the variant name
wifi@a000000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
wifi@a800000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
This would create the boarddata identifiers for the board-2.bin search
* bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
* bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

10.2.4 firmware branch (used in QCA988X) does not support
HTT_10_4_T2H_MSG_TYPE_PEER_STATS and that's why ath10k does not provide
tranmission rate statistics to user space, instead it just shows
hardcoded 6 Mbit/s. But pktlog firmware facility provides per peer tx
statistics. The firmware sends one pktlog event for every four
PPDUs per peer, which include:
* successful number of packets and bytes transmitted
* number of packets and bytes dropped
* retried number of packets and bytes
* rate info per ppdu
Firmware supports WMI_SERVICE_PEER_STATS, pktlog is enabled through
ATH10K_FLAG_PEER_STATS, which is nowadays enabled by default in ath10k.
This patch does not impact throughput.
Tested on QCA9880 with firmware version 10.2.4.70.48. This should also
work with firmware branch 10.2.4-1.0-00029
Parse peer stats from pktlog packets and update the tx rate information

With current NAPI implementation, NAPI poll can deliver more frames
to net core than allotted budget. This may cause warning in napi_poll.
Remaining quota is not accounted, while processing amsdus in
rx_in_ord_ind and rx_ind queue. Adding num_msdus at last can not
prevent delivering more frames to net core. With this change,
all amdus from both in_ord_ind and rx_ind queues are processed and
enqueued into common skb list instead of delivering into mac80211.
Later msdus from common queue are dequeued and delivered depends on
quota availability. This change also simplifies the rx processing in
napi poll routine.

Data packets are not sent by STA in case of STA joined to
non QOS AP (WMM disabled AP). This is happening because of STA
is sending data packets to firmware from host with qos enabled
along with non qos queue value(TID = 16).
Due to qos enabled, firmware is discarding the packet.
This patch fixes this issue by updating the qos based on station
WME capability field if WMM is disabled in AP.

At the moment, spectral scan support, and with it RELAY, is always enabled
with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
RELAY in ath10k, and it unconditionally reserves a relay channel.
Having debugfs support in ath10k is often useful even on very small
embedded routers, where we'd rather like to avoid the code size and RAM
usage of the relay support. While ath10k-based devices usually have more
resources than ath9k-based ones, it makes sense to keep the configuration
symmetric to ath9k, so the same base kernel without RELAY can be used for
both ath9k and ath10k hardware.

cycle between BT and WLAN is such that if BT (including BLE) is active
WLAN gets 0 bandwidth. When tuning these parameters having a too high
value for WLAN means that BLE performance degrades.
The "sweet" point of roughly half of the maximal values was empirically
