d79749f771 ath10k: fix latency issue for QCA988x
(kvalo: cherry picked from commit 1340cc631b in
wireless-drivers-next to wireless-drivers as this a frequently reported
regression)

Bad latency is found on QCA988x, the issue was introduced by
commit 4504f0e5b5 ("ath10k: sdio: workaround firmware UART
pin configuration bug"). If uart_pin_workaround is false, this
change will set uart pin even if uart_print is false.

6b4021deb0 ath10k: add new hw_ops for sdio chip

c6f537a11b ath10k: Add peer delete response event
Peer creation in firmware fails if last peer deletion is still
in progress.

The firmware sends a peer delete response event if it advertises
the service WMI_SERVICE_SYNC_DELETE_CMDS. This peer delete response
event is used to synchronize the peer deletion.

Add peer delete response event and wait for the event after
deleting every peer from host driver to synchronize with firmware.

8b97b055dc ath10k: fix failure to set multiple fixed rate
Currently, below fixed rate commands are broken,
iw wlanx set bitrates legacy-<2.4|5> ht-mcs-<2.4|5> vht-mcs-<2.4|5> \
<NSS:MCSx>
iw wlanx set bitrates legacy-<2.4|5> <legacy rate> ht-mcs-<2.4|5> \
vht-mcs-<2.4|5> <NSS:MCSx>

There are two methods to set fixed rate, both failed,
- Use vdev fixed rate command
  This command only support one single rate, but it's broken due to
  mac80211 change commit e8e4f5280d ("mac80211: reject/clear user
  rate mask if not usable"), which requires user to specify at least
  one legacy rate. So we can't use this command to set ht/vht single
  rate any more.
- Use peer_assoc command
  This command can update rx capability for multiple rates, it will
  work fine for ht mcs rates, as each supported mcs can be advertised
  in ht_mcs index mask. But this will not work with vht rates because,
  as per the vht mcs capability advertisement, there are only two bits
  to indicate the supported mcs. E.g. only support 0-7, 0-8, 0-9.

So introduced new WMI command: WMI_PEER_PARAM_FIXED_RATE. After peer
assoc, the peer fixed rate cmd will work for that specific peer.
Remaining peers will use auto rate. If both vdev fixed rate and peer
fixed rates are given, peer fixed rate will take effect to peers for
which this cmd is given. Remaining peers in that vdev, will use vdev
fixed rate.

4fa42adebe ath10k: enabling tx stats support over pktlog
For QCA988X target, pktlog gives details of the tx bitrate
which is used in the driver for station info.

Enabling pktlog by default will cause more interrupts
in target to host CE pipe, which can impact more CPU usage
for targets ex:WCN3990 and also not required for all other
platforms (eg: WCN3990), for getting tx bitrate.

Enable pktlog only for QCA988X based on hardware params.

9d740d6380 ath10k: Add wrapper function to ath10k debug
ath10k_dbg() is called in ath10k_process_rx() with huge set of arguments
which is causing CPU overhead even when debug_mask is not set.
Good improvement was observed in the receive side performance when call
to ath10k_dbg() is avoided in the RX path.

Since currently all debug messages are sent via tracing infrastructure,
we cannot entirely avoid calling ath10k_dbg. Therefore, call to
ath10k_dbg() is made conditional based on tracing config in the driver.

Trasmit performance remains unchanged with this patch; below are some
experimental results with this patch and tracing disabled.

[...]

ath10k_pci_fw_crashed_dump() is called from NAPI contexts, and firmware
memory dumps are retrieved using the diag memory interface.

A simple reproduction case is to run this on QCA6174A /
WLAN.RM.4.4.1-00132-QCARMSWP-1, which happens to be a way to b0rk the
firmware:

  dd if=/sys/kernel/debug/ieee80211/phy0/ath10k/mem_value bs=4K count=1
of=/dev/null

(NB: simulated firmware crashes, via debugfs, don't trigger firmware
dumps.)

The fix is to move the crash-dump into a workqueue context, and avoid
relying on 'data_lock' for most mutual exclusion. We only keep using it
here for protecting 'fw_crash_counter', while the rest of the coredump
buffers are protected by a new 'dump_mutex'.

I've tested the above with simulated firmware crashes (debugfs 'reset'
file), real firmware crashes (the 'dd' command above), and a variety of
reboot and suspend/resume configurations on QCA6174A.

4504f0e5b5 ath10k: sdio: workaround firmware UART pin configuration bug
On QCA6174 SDIO devices the SDIO interrupt will fail if UART is
disabled from ath10k. SDIO firmware enables UART printouts by
default. If ath10k will try to enable UART again the firmware
will configure it's GPIO line incorrectly and SDIO interrupts
won't work anymore. The workaround is to set UART pin again (19
for QCA6174 SDIO) if uart_print is 0.

f40a307eb9 ath10k: Fill rx duration for each peer in fw_stats for WCN3990
Currently, rx_duration for each peer is not getting populated in
fw_stats debugfs entry for WCN3990.

WCN3990 firmware sends rx duration for each peer as part of
peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats,
firmware expects host to send fw_stats_req_mask with flag
WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD.

Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in
WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in
WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer
in fw_stats debugfs entry.

Currently the driver handles 32-bit rx_duration, but the rx_duration
for WCN3990 can be upto 63 bit. The firmware sends rx_duration split
into two 32-bit fields, with the upper 32-bits being valid only if its
MSB is set. This change handles the 63-bit rx_duration obtained from
WCN3990 and maintain the backward compatibility.

To get the rx_duration of each connected peer :
cat /sys/kernel/debug/ieee80211/phyX/ath10k/fw_stats

05e7ba24b1 ath10k: implement set_base_macaddr to fix rx-bssid mask in multiple APs conf
Many integrated QCA9984 WiFis in various IPQ806x platform routers
from various vendors (Netgear R7800, ZyXEL NBG6817, TP-LINK C2600,
etc.) have either blank, bogus or non-unique MAC-addresses in
their calibration data.

As a result, OpenWrt utilizes a discouraged binary calibration data
patching method that allows to modify the device's MAC-addresses right
at the source. This is because the ath10k' firmware extracts the MAC
address from the supplied radio/calibration data and issues a response
to the ath10k linux driver. Which was designed to take the main MAC in
ath10k_wmi_event_ready().

Part of the "setting an alternate MAC" issue was already tackled by a
patch from Brian Norris:
commit 9d5804662c
("ath10k: retrieve MAC address from system firmware if provided")
by allowing the option to specify an alternate MAC-address with the
established device_get_mac_address() function which extracts the right
address from DeviceTree/fwnode mac-address or local-mac-address
properties and saves it for later.

However, Ben Greear noted that the Qualcomm's ath10k firmware is liable
to not properly calculate its rx-bssid mask in this case. This can cause
issues in the popluar "multiple AP with a single ath10k instance"
configurations.

To improve MAC address handling, Felix Fietkau suggested to call
pdev_set_base_macaddr_cmdid before bringing up the first vif and
use the first vif MAC address there. Which is in ath10k_core_start().

This patch implement Felix Fietkau's request to
"call pdev_set_base_macaddr_cmdid before bringing up the first vif".
The pdev_set_base_macaddr_cmdid is already declared for all devices
and version. The driver just needed the support code for this
function.

7ba31e6e0c ath10k: assign 'n_cipher_suites = 11' for WCN3990 to enable WPA3
Hostapd uses CCMP, GCMP & GCMP-256 as 'wpa_pairwise' option to run WPA3.
In WCN3990 firmware cipher suite numbers 9 to 11 are for CCMP,
GCMP & GCMP-256.

To enable CCMP, GCMP & GCMP-256 cipher suites in WCN3990 firmware,
host sets 'n_cipher_suites = 11' while initializing hardware parameters.

53884577fb ath10k: skip sending quiet mode cmd for WCN3990
HL2.0 firmware does not support setting quiet mode.  If the host driver sends
the quiet mode setting command to the HL2.0 firmware, it crashes with the below
signature.

fatal error received: err_qdi.c:456:EX:wlan_process:1:WLAN RT:207a:PC=b001b4f0

The quiet mode command support is exposed by the firmware via thermal throttle
wmi service. Enable ath10k thermal support if thermal throttle wmi service bit
is set.  10.x firmware versions support this feature by default, but
unfortunately do not advertise the support via service flags, hence have to
manually set the service flag in ath10k_core_compat_services().

Tested on QCA988X with 10.2.4.70.9-2. Also tested on WCN3990.

13104929d2 ath10k: fill the channel survey results for WCN3990 correctly
The host driver currently expects the channel info event to be
received in pairs for all the channels, i.e. the first
chan_info event for a particular channel will not have the
COMPLETE flag set and the second chan_info event for the
same channel will have the COMPLETE flag set.

The HL2.0 firmware sends only one channel info event per channel
which is scanned without the COMPLETE flag set. After sending the
chan_info_event for all the channels, the HL2.0 firmware sends a
chan_info_event with COMPLETE flag set to indicate the completion
of the channel info event.

The firmware does not indicate this behavior with any service bitmap
and hence a new firmware feature flag is used to handle the modified
parsing of the channel info events, in the host driver, for the
firmware which sends single channel info event per scanned channel.

0e622f67e0 ath10k: add support for WCN3990 firmware crash recovery
Whenever the WCN3990 firmware becomes unavailable,
the host driver receives a FW down indication, post
which all the direct hardware register access should
be avoided, in order to prevent improper behavior in
the host driver.

Set the crash_flush flag when the host driver receives
a FW_DOWN_IND via qmi, in order to stop the untimely
hardware register access. Also handle the case, where
we need to do core register only for the first FW_READY
indication, which is when we initialize the host driver.
All the subsequent FW_READY indication will be received
in subsystem recovery case and we only need to do the
restart work. The state of driver is maintained using
flags to distinguish between first and subsequent FW_READY
indication received.

08fafd646d ath10k: remove num_peers in hw_params for most targets
>From commit "ath10k: add per target config of max_num_peers",
the num_peers value in struct ath10k_hw_params is used to override
the value obtained from the WMI op version in the firmware file.

Currently, only high latency devices (USB and SDIO) need to use this
value, since the value obtained from the WMI op version is not
applicable for these devices.

Many devices in ath10k_hw_params_list have the wrong value set.

An example of this is the QCA9880 hw2.0 chipset that had (before this
patch) num_peers set to TARGET_TLV_NUM_PEERS although the firmware
uses WMI version ATH10K_FW_WMI_OP_VERSION_10_2_4.

Using the wrong value for the QCA9880 chip results in a fw crash:

39501ea641 ath10k: download firmware via diag Copy Engine for QCA6174 and QCA9377.
Downloading firmware via BMI protocol takes too long time. For example,
a ~700K bytes firmware takes about 500ms to download via BMI protocol.
This is too long especially in suspend and resume scenario where firmware
is re-downloaded unless WoWLAN is enabled. Downloading firmware via diag CE
can reduce the time to ~40ms for a ~700K bytes firmware binary.

Ath10k driver parses the firmware to segments and downloads the segments
to the specified address directly. If the firmware is compressed or has
unsupported segments, ath10k driver will try BMI download again.

It's tested with QCA6174 hw3.2 and

31324d1797 ath10k: support extended board data download for dual-band QCA9984
To support dual-band variant of QCA9984, new extended board data (eBDF)
is introduced since existing board data ran out of space.

Below is the brief implementation & design detail,
----------------------------------------------------

1. New OTP changes to inform eBDF support in existing OTP download to
fetch board ID and chip ID. This is backward compatible and older
card sends 0 by default for eBDF support bit (bit 18 of OTP response) we
check in ath10k driver.

2. If eBDF is supported, then we need to fetch eBDF ID which is bundled
in downloaded board data. So again OTP is executed for knowing the eBDF ID.
This is done once we set 'board_data_initialized' bit. If eBDF ID
returned is zero, we continue booting with previous board data downloaded.

3. Based on the eBDF ID fetched, ath10k driver tries to download the
extended board data to a new offset ahead of already downloaded board
data address.

4. A new BD IE type, ATH10K_BD_IE_BOARD_EXT is added to differentiate in
bundling eBDF separately in board-2.bin and also to parse through
board bundle for eBDF download in ath10k boot.

5. If eBDF is not present in the board-2.bin bundle or when board ID is
zero, we do a fallback boot to "eboard.bin" in the same QCA9984/hw1.0 dir.
This is same as done to existing "board.bin" if board ID is not present
in board-2.bin bundle.

Current design is that eBDF size will be 2KB and eBDF ID will be
byte value.

Tested the above changes with dual-band variant of QCA9984 card. OTP
update needed for the test will be part of next FW release 10.4-3.6-xxxx.

Below are the logs with ath10k BOOT debugs enabled.

First OTP response :
---------------------

9d5804662c ath10k: retrieve MAC address from system firmware if provided
Devices may provide their own MAC address via system firmware (e.g.,
device tree), especially in the case where the device doesn't have a
useful EEPROM on which to store its MAC address (e.g., for integrated
Wifi).

Use the generic device helper to retrieve the MAC address, and (if
present) honor it above the MAC address advertised by the card.

58da3b4230 ath10k: skip resetting rx filter for WCN3990
WCN3990 has the MAC_PCU_ADDR1 configured properly
and hence it will not send spurious ack frames
during boot up.

Hence the reset_rx_filter workaround is not needed
for WCN3990. Add a hw_param to indicate if hardware rx
filter reset is needed and skip the reset_rx_filter for
WCN3990.

Tested HW: WCN3990
Tested FW: WLAN.HL.2.0-01188-QCAHLSWMTPLZ-1

dc405152bb ath10k: handle mgmt tx completion event
WCN3990 transmits management frames via WMI
with reference. Currently, with the management
tx completion not being handled, these frames are
not getting freed even after the transmission status
is returned by the firmware.

The transmitted management frames should be freed
when the firmware sends the over-the-air tx status of
the corresponding management frames.

Handle the wmi mgmt tx completion event and free
the corresponding management frame.

Tested HW: WCN3990
Tested FW: WLAN.HL.2.0-01188-QCAHLSWMTPLZ-1
