If there are some tx packets pending in firmware, and then system
enters suspend, firmware will fail for wow enable. This will trigger
mac80211 to stop ath10k and download firmware again, then it is
non-wow suspend.
After add the waiting htt tx complete, then firmware will have some
time window to send or flush the pending tx packets.

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.

Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
the RX and TX path. These filtered channel can in theory still be used by
the hardware but the signal strength is reduced so much that it makes no
sense.
There is already a DT property to limit the available channels but ath10k
has to manually call this functionality to limit the currrently set wiphy
channels further.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This issue was detected with the help of Coccinelle.

When running in AP mode, ath10k sometimes suffers from TX credit
starvation. The issue is hard to reproduce and shows up once in a
few days, but has been repeatedly seen with QCA9882 and a large
range of firmwares, including 10.2.4.70.67.
Once the module is in this state, TX credits are never replenished,
which results in "SWBA overrun" errors, as no beacons can be sent.
Even worse, WMI commands run in a timeout while holding the conf
mutex for three seconds each, making any further operations slow
and the whole system unresponsive.
The firmware/driver never recovers from that state automatically,
and triggering TX flush or warm restarts won't work over WMI. So
issue a hardware restart if a WMI command times out due to missing
TX credits. This implies a connectivity outage of about 1.4s in AP
mode, but brings back the interface and the whole system to a usable
state. WMI command timeouts have not been seen in absent of this
specific issue, so taking such drastic actions seems legitimate.

When continuously running wifi up/down sequence, the napi poll
can be scheduled after the CE buffers being freed by ath10k_pci_flush
Steps:
In a certain condition, during wifi down below scenario might occur.
ath10k_stop->ath10k_hif_stop->napi_schedule->ath10k_pci_flush->napi_poll(napi_synchronize).
In the above scenario, CE buffer entries will be freed up and become NULL in
ath10k_pci_flush. And the napi_poll has been invoked after the flush process
and it will try to get the skb from the CE buffer entry and perform some action on that.
Since the CE buffer already cleaned by pci flush this action will create NULL
pointer dereference and trigger below kernel panic.

The QCA4019 hw1.0 firmware 10.4-3.2.1-00050 and 10.4-3.5.3-00053 (and most
likely all other) seem to ignore the WMI_CHAN_FLAG_DFS flag during the
scan. This results in transmission (probe requests) on channels which are
not "available" for transmissions.
Since the firmware is closed source and nothing can be done from our side
to fix the problem in it, the driver has to work around this problem. The
WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not
scan actively on a channel unless an AP was detected on it. Simple probe
requests will then be transmitted by the STA on the channel.
ath10k must therefore also use this flag when it queues a radar channel for
scanning. This should reduce the chance of an active scan when the channel
might be "unusable" for transmissions.

Debugfs support to do hardware warm reset with WMI command
WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi
service is enabled in the firmware for backward compatibility).
This change is purely for debugging purpose when hardware hangs/mutes.
This hardware reset won't affect the connectivity but there will be small
pause in data traffic. Here we are doing BB/MAC level reset and hence
whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset.
So the target will be in the active state.

support needs to be disabled in the wmi init cmd, sent to the firmware.

to let firmware know the features supported by the host driver.
This field is ignored if it is not supported by firmware.
Set the host capability indication flag(i.e. host_capab) to zero,
for disabling the support of bundle mgmt tx completion. This will
indicate the firmware to send completion event for every mgmt tx
completion, instead of bundling them together and sending in a single

The hardcoded values used in ath10k_mac_tx_push_pending and
ath10k_mac_op_wake_tx_queue set an upper limit of how many packets that
can be consumed from the TX queue.
HTC_HOST_MAX_MSG_PER_TX_BUNDLE is a proper name for this constant, as
the value effectively limits the number of messages that can be consumed
in one step. Thus, the value is an upper limit of the number of messages
that can be added to a TX message bundle.

There are frames in the ieee80211_txq and there are frames that have
been removed from from this queue, but haven't yet been sent on the wire
(num_pending_tx).
When num_pending_tx reaches max_num_pending_tx, we will stop the queues
by calling ieee80211_stop_queues().
As frames that have previously been sent for transmission
(num_pending_tx) are completed, we will decrease num_pending_tx and wake
the queues by calling ieee80211_wake_queue(). ieee80211_wake_queue()
does not call wake_tx_queue, so we might still have frames in the
queue at this point.
While the queues were stopped, the socket buffer might have filled up,
and in order for user space to write more, we need to free the frames
in the queue, since they are accounted to the socket. In order to free
them, we first need to transmit them.
This problem cannot be reproduced on low-latency devices, e.g. pci,
since they call ath10k_mac_tx_push_pending() from
ath10k_htt_txrx_compl_task(). ath10k_htt_txrx_compl_task() is not called
on high-latency devices.
Fix the problem by calling ath10k_mac_tx_push_pending(), after
processing rx packets, just like for low-latency devices, also in the
SDIO case. Since we are calling ath10k_mac_tx_push_pending() directly,
we also need to export it.

In the case of Station connects to AP with narrower bandwidth at beginning.
And later the AP changes the bandwidth to winder bandwidth, the AP will
beacon with wider bandwidth IE, eg VHT20->VHT40->VHT80 or VHT40->VHT80.
Since the supported BANDWIDTH will be limited by the PHYMODE, so while
Station receives the bandwidth change request, it will also need to
reconfigure the PHYMODE setting to firmware instead of just configuring
the BANDWIDTH info, otherwise it'll trigger a firmware crash with

The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in wireless-drivers by changing it to BIT_ULL instead. In addition, there are
some places which don't use BIT nor BIT_ULL macros so align those as well.

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).

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.

Usage of the collected info is specific to driver implementation.
For example, collected radar info could be used by the host driver
to send to co-processors for additional processing/validation.
Note: 'radar_detector_specs' data containing the specifications of
different radar types which was private within dfs_pattern_detector/
dfs_pri_detector is now shared with drivers as well for making use

ath10k_mac_tx_push_txq returns either a postive integer (length) on

The "if (ret) break;" statement will thus always break out of the loop
immediately after ath10k_mac_tx_push_txq has returned (making the loop
pointless).
A side effect of this fix is that we will iterate the queue until
ath10k_mac_tx_push_txq returns -ENOENT. This will make sure the queue is
not added back to ar->txqs when it is empty. This could potentially
improve performance somewhat (I have seen a small improvement with SDIO

When trying to set wow wakeup patterns it fails with this command:

The reason is that the wow pattern from upper layer is in 802.3 format
for this case, it need to convert it to 802.11 format. The input
offset parameter is used for 802.3, but the actual offset firmware
need depends on rx_decap_mode, so that it needs to be recalculated.
Pattern of 802.3 packet is not same with 802.11 packet. If the

commit f2593cb1b2 ("ath10k: Search SMBIOS for OEM board file
extension") added a feature to ath10k that allows Board Data File
(BDF) conflicts between multiple devices that use the same device IDs
but have different calibration requirements to be resolved by allowing
a "variant" string to be stored in SMBIOS [and later device tree, added
by commit d06f26c5c8 ("ath10k: search DT for qcom,ath10k-calibration-
variant")] that gets appended to the ID stored in board-2.bin.
This original patch had a regression, however. Namely that devices with
a variant present in SMBIOS that didn't need custom BDFs could no longer
find the default BDF, which has no variant appended. The patch was
reverted and re-applied with a fix for this issue in commit 1657b8f84e
("search SMBIOS for OEM board file extension").
But the fix to fall back to a default BDF introduced another issue: the
driver currently parses IEs in board-2.bin one by one, and for each one
it first checks to see if it matches the ID with the variant appended.
If it doesn't, it checks to see if it matches the "fallback" ID with no
variant. If a matching BDF is found at any point during this search, the
search is terminated and that BDF is used. The issue is that it's very
possible (and is currently the case for board-2.bin files present in the
ath10k-firmware repository) for the default BDF to occur in an earlier
IE than the variant-specific BDF. In this case, the current code will
happily choose the default BDF even though a better-matching BDF is
present later in the file.
This patch fixes the issue by first searching the entire file for the ID
with variant, and searching for the fallback ID only if that search
fails. It also includes some code cleanup in the area, as
ath10k_core_fetch_board_data_api_n() no longer does its own string
mangling to remove the variant from an ID, instead leaving that job to a
new flag passed to ath10k_core_create_board_name().
I've tested this patch on a QCA4019 and verified that the driver behaves
correctly for 1) both fallback and variant BDFs present, 2) only fallback
BDF present, and 3) no matching BDFs present.

WCN3990 is integrated 802.11ac chipset with SNOC
bus interface. Add snoc layer driver registration
and associated ops.
WCN3990 support is not yet complete as cold-boot
handshake is done using qmi(Qualcomm-MSM-Interface)
and qmi client support will be added once qmi framework
is available.

CE layer is shared between pci and snoc target and results
in duplicate object inclusion if both modules are compiled
together statically and undefined KBUILD_MODNAME if
compiled as module.
Fix this by building ce layer in ath10k core module by
adding ce object inclusion with ATH10K_CE boolean CONFIG.
