6df0580be8 ath9k: add back support for using active monitor interfaces for tx99
Various documented examples on how to set up tx99 with ath9k rely
on setting up a regular monitor interface for setting the channel.
My previous patch "ath9k: fix tx99 with monitor mode interface" made
it possible to set it up this way again. However, it was removing support
for using an active monitor interface, which is required for controlling
the bitrate as well, since the bitrate is not passed down with a regular
monitor interface.

This patch partially reverts the previous one, but keeps support for using
a regular monitor interface to keep documented steps working in cases
where the bitrate does not matter

It seems like the lower 3 bits on my hardware are always zeroed, but the
magnitude matches otherwise. Therefore, let's not make the magnitude
check so strict so we can get those samples released to userspace.

FFT max index retrieval was not retrieved correctly for HT20/HT40 FFT
frames. Fixing the retrieval allows us to remove the fixup function as
well. While at it, split the spectral_max_index function into versions

d70c0d463f ath10k: add debugfs support to get power save state change of STA
This patch helps to get the power save state change of each peer
connected to the AP. With WMI_10_4_PEER_STA_PS_STATECHG_EVENTID
event, ps state of each peer is reported to user space via
debugfs.

Use the below command to get the ps state of each sta:
cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/
XX:XX:XX:XX:XX:XX/peer_ps_state

If STA is in power save state, we get the peer_ps_state value as 1.
if STA is not in power save state, we get the peer_ps_state value as 0.
If ps_state event is disabled, we get the peer_ps_state value as 2.

We can enable/disable the ps_state events using the debugfs flag
"ps_state_enable"

echo Y > /sys/kernel/debug/ieee80211/phyX/ath10k/ps_state_enable

Y = 1 to enable and Y = 0 to disable

f279294e9e ath10k: add support for configuring management packet rate
By default the firmware uses 1Mbps and 6Mbps rate for management packets
in 2G and 5G bands respectively. But when the user selects different
basic rates from the userspace, we need to send the management
packets at the lowest basic rate selected by the user.

This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
management packets rate to the firmware.

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:

234e4307cf ath10k: utilize random MAC address if none is provided
Since commit 9d5804662c ("ath10k: retrieve MAC address from system
firmware if provided"), we support pulling our MAC address from system
firmware. Along with this, we should admit that it's possible for system
firmware to be screwed up as well, omitting the MAC address there.

Provide a fallback, such that we choose a randomly-generated MAC
address, with the local assignment bit set.

This is not a preferred mode of operation and really should only serve
the purpose of keeping the system chugging along while someone figures
out what's wrong with the system. Grepping through other wireless
drivers shows very similar fallback logic though, so why not?

37f62c0d58 ath10k: wmi: disable softirq's while calling ieee80211_rx
This is done in order not to trig the below warning in
ieee80211_rx_napi:

WARN_ON_ONCE(softirq_count() == 0);

ieee80211_rx_napi requires that softirq's are disabled during
execution.

The High latency bus drivers (SDIO and USB) sometimes call the wmi
ep_rx_complete callback from non softirq context, resulting in a trigger
of the above warning.

Calling ieee80211_rx_ni with softirq's already disabled (e.g., from
softirq context) should be safe as the local_bh_disable and
local_bh_enable functions (called from ieee80211_rx_ni) are fully
reentrant.

f88d493450 ath10k: htt: High latency RX support
Special HTT RX handling for high latency interfaces.

Since no DMA physical addresses are used in the RX ring
config message (this is not supported by the high latency
devices), no RX ring is allocated.
All RX skb's are allocated by the driver and passed directly
to mac80211 in the HTT RX indication handler.

A nice side effect of this is that no huge buffer will be
allocated with dma_alloc_coherent. On embedded systems with
limited memory resources, the allocation of the RX ring is
prone to fail.

Some tweaks made to "make it work":

Removal of protected bit in 802.11 header frame control field.
The chipset seems to do hw decryption but the frame_control
protected bit is still set.

This is necessary for mac80211 not to drop the frame.

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

bc346c9a24 ath10k: support to access target space below 1M for qca6174 and qca9377
To download firmware via diag interface, driver needs to write the target
memory space below 1M. It means the bit20 should be zero for the converted
address if the target memory space is below 1M. Otherwise, bit20 is one if
the target address is larger or equal to 1M space.

As downloading firmware via diag interface is only required for qca6174
and qca9377, a new specific function is introduced to convert the target
address to ce address: ath10k_pci_qca6174_targ_cpu_to_ce_addri().
This function supports to convert any target address to ce address.

d56bbeea25 ath10k: optimize pci diag mem read & write operations
Delay 1ms is too long for both diag read and write operations.
This is observed when writing a big memory buffer to target or
reading a big memory buffer from target. Take writing/reading
512k bytes as example, the delay itself is 256ms as the maximum
length of every write/read is 2k size.

Reduce the delay to 50us for read and write operations.

Take the ath10k_pci_targ_cpu_to_ce_addr() out of loop and put it
in the beginning of the loop for ath10k_pci_diag_read_mem().

The ath10k_pci_targ_cpu_to_ce_addr() is to convert the address
from target cpu's perspective to CE's perspective, so it makes
no sense to convert a CE's perspective address again in the loop.
It's a wrong implementation but happens to work.

If the target address is below 1M space, then the convert in the loop
from the second time becomes wrong because the previously converted address
is larger than 1M. The counterpart ath10k_pci_diag_write_mem() has the
correct implementation.

With this change, ath10k_pci_diage_read_mem() works correctly no matter
the target address is below 1M or above 1M.

It's tested with QCA6174 hw3.2 and
firmware-6.bin_WLAN.RM.4.4.1-00111-QCARMSWP-1. QCA9377 is also affected.

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 :
---------------------
