Currently host can send two WMI commands at once. There is possibility to
cause SMMU issues or corruption, if host wants to initiate 2 DMA
transfers, it is possible when copy complete interrupt for first DMA
reaches host, CE has already updated SRRI (Source ring read index) for
both DMA transfers and is in the middle of 2nd DMA. Host uses SRRI
(Source ring read index) to interpret how many DMA’s have been completed
and tries to unmap/free both the DMA entries. Hence now it is limiting to
one.Because CE is still in the middle of 2nd DMA which can cause these
issues when handling two DMA transfers.
This change will not impact other targets, as it is only for WCN3990.

Currently after the hardware restart triggered from the driver,
the station interface connection remains intact, since a disconnect
trigger is not sent to userspace. This can lead to a problem in
targets where the wifi mac sequence is added by the firmware.
After the target restart, its wifi mac sequence number gets
reset to zero. Hence AP to which our device is connected will receive
frames with a wifi mac sequence number jump to the past, thereby
resulting in the AP dropping all these frames, until the frame
arrives with a wifi mac sequence number which AP was expecting.
To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.
The other targets are not affected by this change, since the hardware
params flag is not set.

QCA6174 card often hangs with the current htt_rx_desc
memory layout in some circumstances, because its firmware
fails to handle length differences.
Therefore we must abstract the htt_rx_desc structure
and operations on it, to allow different wireless cards
to use different, unrelated rx descriptor structures.
Define a base htt_rx_desc structure and htt_rx_desc_v1
for use with the QCA family of ath10k supported cards
and htt_rx_desc_v2 for use with the WCN3990 card.
Define htt_rx_desc_ops which contains the abstract operations
to access the generic htt_rx_desc, give implementations
for each card and update htt_rx.c to use the defined
abstract interface to rx descriptors.

On an imx6dl-pico-pi board with a QCA9377 SDIO chip, simply trying to
connect via ssh to another machine causes:
[ 55.824159] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12
[ 55.832169] ath10k_sdio mmc1:0001:1: failed to submit frame: -12

[ 55.919887] ath10k_sdio mmc1:0001:1: failed to push frame: -12
, leading to an ssh connection failure.
One user inspected the size of frames on Wireshark and reported
the followig:
"I was able to narrow the issue down to the mtu. If I set the mtu for
the wlan0 device to 1486 instead of 1500, the issue does not happen.
The size of frames that I see on Wireshark is exactly 1500 after
setting it to 1486."
Clearing the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE avoids the problem and
the ssh command works successfully after that.
Introduce a 'credit_size_workaround' field to ath10k_hw_params for
the QCA9377 SDIO, so that the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE
is not set in this case.
Tested with QCA9377 SDIO with firmware WLAN.TF.1.1.1-00061-QCATFSWPZ-1.

ath10k assigns ath10k_mac_set_sar_specs to ath10k_ops, and
this function is called when user space application calls
NL80211_CMD_SET_SAR_SPECS. ath10k also registers SAR type,
and supported frequency ranges to wiphy so user space can
query SAR capabilities.
This SAR power limitation is compared to regulatory txpower
and selects the minimal one to set when station is connected.
Otherwise, it delays until the station is connected. If the
station is disconnected, it returns to regulatory txpower.
This feature is controlled by hw parameter: dynamic_sar_support.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

For SDIO chip, its rx indication is struct htt_rx_indication_hl, which
does not include the bitrate info as well as PCIe, for PCIe, it use
function ath10k_htt_rx_h_rates to parse the bitrate info in struct
rx_ppdu_start and then report it to mac80211 via ieee80211_rx_status.
SDIO does not have the same info as PCIe, then iw command can not get
the rx bitrate by "iw wlan0 station dump".
for example, it always show 6.0 MBit/s
localhost ~ # iw wlan0 link
Connected to 3c:28:6d:96:fd:69 (on wlan0)
SSID: kukui_test
freq: 5180
RX: 111800 bytes (595 packets)
TX: 35419 bytes (202 packets)
signal: -41 dBm
rx bitrate: 6.0 MBit/s
This patch is to send WMI_TLV_REQUEST_PEER_STATS_INFO_CMDID to firmware
for ath10k_sta_statistics and save the rx bitrate for WMI event
WMI_TLV_PEER_STATS_INFO_EVENTID.
This patch only effect SDIO chip, ath10k_mac_sta_get_peer_stats_info
has check for bitrate_statistics of hw_params, this patch only enable

For sdio chip, it is high latency bus, all the TX packet's content will
be tranferred from HOST memory to firmware memory via sdio bus, then it
need much more memory in firmware than low latency bus chip, for low
latency chip, such as PCI-E, it only need to transfer the TX descriptor
via PCI-E bus to firmware memory. For sdio chip, reduce the complexity of
TX logic will help TX efficiency since its memory is limited, and it will
reduce the TX circle's time of each packet and then firmware will have more
memory for TX since TX complete also need memeory.
This patch disable TX complete indication from firmware for htt data
packet, it will not have TX complete indication from firmware to ath10k.
It will cut the cost of bus bandwidth of TX complete and make the TX
logic of firmware simpler, it results in significant performance
improvement on TX path.
Udp TX throughout is 130Mbps without this patch, and it arrives
400Mbps with this patch.
The downside of this patch is the command "iw wlan0 station dump" will
show 0 for "tx retries" and "tx failed" since all tx packet's status
is success.
This patch only effect sdio chip, it will not effect PCI, SNOC etc.

This reverts commit 76d164f582150fd0259ec0fcbc485470bcd8033e.
PCIe hung issue was observed on multiple platforms. The issue was reproduced
when DUT was configured as AP and associated with 50+ STAs.
For QCA9984/QCA9888, the DMA_BURST_SIZE register controls the AXI burst size
of the RD/WR access to the HOST MEM.
0 - No split , RAW read/write transfer size from MAC is put out on bus
as burst length
1 - Split at 256 byte boundary
2,3 - Reserved
With PCIe protocol analyzer, we can see DMA Read crossing 4KB boundary when
issue happened. It broke PCIe spec and caused PCIe stuck. So revert
the default value from 0 to 1.

When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_TLV_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath10k will check the capability, and if it is enabled then
ath10k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath10k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware to enable/disable the radio
and also notifies cfg80211.
We can't power off the device when rfkill is enabled, as otherwise the
firmware would not be able to detect GPIO changes and report them to the
host. So when rfkill is enabled, we need to keep the firmware running.

WCN3990 is a 37-bit target but can address memory range
only upto 35 bits. The 36th bit is used to control the
smmu/iommu translation and the 37th bit is used by the
internal bus masters to access the wifi subsystem internal
SRAM. With the DMA mask set to 37i-bit, the host driver
can get 37-bit dma address, which leads to incorrect
address access in the target.
Hence the host driver can used addresses upto 35-bit
for WCN3990. Fix the dma mask for wcn3990 to 35-bit,
instead of 37-bit.

Some hardwares variants (QCA99x0) are limiting msdu deaggregation with
some threshold value(default limit in QCA99x0 is 64 msdus), it was introduced to
avoid excessive MSDU-deaggregation in error cases. When number of sub frames
exceeds the limit, target hardware will send all msdus starting from present
msdu in RAW format as a single msdu packet and it will be indicated with
error status bit "RX_MSDU_END_INFO0_MSDU_LIMIT_ERR" set in rx descriptor.
This msdu frame is a partial raw MSDU and does't have first msdu and ieee80211
header. It caused below warning message.

[ 320.155006] WARNING: CPU: 0 PID: 3 at drivers/net/wireless/ath/ath10k/htt_rx.c:1188
In our issue case, MSDU limit error happened due to FCS error and generated
this warning message.
This fixes the warning by handling the MSDU limit error. If msdu limit error
happens, driver adds first MSDU's ieee80211 header and sets A-MSDU present bit
in QOS header so that upper layer processes this frame if it is valid or drop it
if FCS error set. And removed the warning message, hence partial msdus without
first msdu is expected in msdu limit error cases.

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.

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.

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.

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.

The spectral scan has been always broken on QCA9984 and QCA9888.
Introduce a hardware parameter 'spectral_bin_offset' to resolve this issue for
QCA9984 and QCA9888 chipsets. For other chipsets, the hardware parameter
'spectral_bin_offset' is zero so that existing behaviour is retained as it is.
In QCA9984 and QCA9888 chipsets, hardware param value 'spectral_bin_discard'
is 12 bytes. This 12 bytes is derived as the sum of segment index (4 bytes),
extra bins before the actual data (4 bytes) and extra bins after the actual
data (4 bytes). Always discarding (12 bytes) happens at end of the samples and
incorrect samples got dumped, so that user can find incorrect arrangement
samples in spectral scan dump.
To fix this issue, we have to discard first 8 bytes and last 4 bytes in every
samples, so totally 12 bytes are discarded. In every sample we need to consider
the offset while taking the actual spectral data. For QCA9984, QCA9888 the
offset is 8 bytes (segment index + extra bins before actual data).
Hardware tested: QCA9984 and QCA9888
Firmware tested: 10.4-3.5.3-00053

SRRI/DRRI are not mapped in the HW Shadow block and can lead
to un-clocked access if common subsystem in the target is
powered down due to idle mode.
To mitigate this problem SRRI/DRRI can be read from
DDR instead of doing an actual hardware read.
Host allocates non cached memory on ddr and configures
the physical address of this memory to the CE hardware.
The hardware updates the RRI on this particular location.
Read SRRI/DRRI from DDR location instead of
direct target read.
Enable retention restore on ddr using hw params to enable
in specific targets.

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).

QCA9984 hardware can do 4x4 at 80Mhz, but only 2x2 at 160Mhz.
First, report this to user-space by setting the max-tx-speed
and max-rx-speed vht capabilities.
Second, if the peer rx-speed is configured, and if we
are in 160 or 80+80 mode, and the peer rx-speed matches
the max speed for 2x2 or 1x1 at 160Mhz (long guard interval),
then use that info to set the peer_bw_rxnss_override appropriately.
Without this, a 9984 firmware will not use 2x2 ratesets when
transmitting to peer (it will be stuck at 1x1), because
the firmware would not have configured the rxnss_override.
