Subject: ath10k: fix NAPI enable/disable symmetry for AHB interface

Move NAPI enable to 'ath10k_ahb_hif_start' from
'ath10k_ahb_hif_power_up'. This is to maintain the symmetry
of calling napi_enable() from ath10k_ahb_hif_start() so that it
matches with  napi_disable() being called from ath10k_pci_hif_stop().

This change is based on the crash fix from Kalle for PCI interface in
commit 1427228d5869 ("ath10k: fix napi crash during rmmod when probe
firmware fails").

Subject: ath10k: fix station nss computation

If station advertises diffferent NSS capabilities in Rx_mcs set
of HT and VHT IEs in assoc req, the current NSS computation
logic configures the NSS support only based on Rx_mcs set of
HT capabilities in the driver. This is configuring the station
NSS capabilities incorreclty in the target.

For example, if station advertise Rx_mcs set as 2 spatial streams
in HT capabilities and 1 spatial streams in VHT capabilities in
assoc request, as per current logic we are calculating nss from
HT capabilities and the driver sets peer_num_spatial_streams as
2 for the station which is configured in VHT 1*1.

This patchs fix this issue by calculating the nss from VHT cap if
station supports vht.

It seems set_coverage_class_work is not cancelled anywhere,
though I could not find a crash/warning  with this existing
design, its safer to cancel it during stop() and also before
restarting the hardware.

Subject: iwlwifi: mvm: support new binding API

For a000 devices the binding API needs to include relevant
lmac ID - support the new API.
The new API should be used regardless if the device had CDB or
not. If there is no actual CDB support the binding is bound
to first lmac regardless of the band.
There are some functionality changes in binding restrictions
and quota allocations that will be handled in future patches.

Subject: iwlwifi: be more verbose about needed firmware

If the supported firmware versions are not found, we currently only
print "no suitable firmware found".  This is not very informative for
the user trying to find the correct version to use.  Improve this by
printing the exact firmware name(s) the driver supports and pointing
to the git repository where they can be found.

Subject: iwlwifi: mvm: fix RX SKB header size and align it properly

When receiving a frame, we currently pull in sizeof(*hdr) plus
some extra (crypto/snap), which is too much, most headers aren't
actually sizeof(*hdr) since that takes into account the 4-address
format but doesn't take into account QoS. As a result, a typical
frame will have 4 bytes of the payload in the SKB header already.

Fix this by calculating the correct header length, and now that
we have that, align the end of the SKB header to a multiple of 4
so that the IP header will be aligned properly when pulled in.

Subject: iwlwifi: pcie: print less data upon firmware crash

We don't need to print so much data in the kernel log.
Limit the data to be printed to the queue that actually
got stuck in case of a TFD queue hang, and stop dumping
all the CSR and FH registers. Over the course of time, the
CSR and FH values haven't proven themselves to be really
useful for debugging, and they are now in the firmware dump
anyway.

This comes as a preparation to the addition of more data
required to be printed by the firwmare team.

Subject: iwlwifi: mvm: cleanup pending frames in DQA mode

When a station is asleep, the fw will set it as "asleep".
All queues that are used only by one station will be stopped by
the fw.

In pre-DQA mode this was relevant for aggregation queues. However,
in DQA mode a queue is owned by one station only, so all queues
will be stopped.
As a result, we don't expect to get filtered frames back to
mac80211 and don't have to maintain the entire pending_frames
state logic, the same way as we do in aggregations.

The correct behavior is to align DQA behavior with the aggregation
queue behaviour pre-DQA:
- Don't count pending frames.
- Let mac80211 know we have frames in these queues so that it can
properly handle trigger frames.

When a trigger frame is received, mac80211 tells the driver to send
frames from the queues using release_buffered_frames.
The driver will tell the fw to let frames out even if the station
is asleep. This is done by iwl_mvm_sta_modify_sleep_tx_count.

Subject: iwlwifi: mvm: add multicast station

Currently multicast queue is associated with the broadcast
station.

This raises quite a few issues:

The multicast queue has a special treatment:
- It is sent in the MAC context command
- It is excluded from tfd_queue_mask

In DQA mode we end up enabling two queues - the probe response
queue and the multicast queue - with the same station (broadcast)
and TID while in DQA mode it should be unique RA-TID.
Firmware will enforce it for a000 devices, so this allocation
will fail.

In addition, in a000 devices the FW will set the FIFO and not
the driver. So there is a need for FW to know when we enable
the queue that it is multicast queue so it will be bound to
the multicast FIFO. There is no such way in current design.

In order to simplify driver and firmware handling of this queue
create a multicast station.
This solves the unique RA-TID issue in the short term and serves
as preparation for the long term.

In the long term we will also add a flag marking this station for
the FW as the multicast station.
Once we will do that the FW will know this is the multicast queue
immediately when it is added and bind it to the correct FIFO.
It will also enable removing the special treatment of the
queue in the MAC context command.

Subject: iwlwifi: mvm: support new ADD_MODIFY_STA_KEY command

The command was changed to support PN offload and TKIP offload.
The FW will do TKIP calculations in D0 only for a000 devices,
but API is aligned anyway.
However, for all devices we can stop sending the wowlan tkip
command.
Firmware will fetch the keys from the station key command.

Subject: iwlwifi: mvm: optimize reorder timeout frame releasing

Currently we release up to the last expired frame.
However, if there are consecutive frames after it - we can
optimize it further and release them as well - until the next
hole.

Subject: iwlwifi: mvm: don't assume static queue numbers

In a000 devices FW will assign the queue number. Prepare for
that by getting rid of static defines and store them in variables.
Enlarge to u16 since we may have up to 512 queues.

Subject: iwlwifi: mvm: support MFUART dump in case of MFUART assert

In case of a MFUART assert, get a notification from the fw
that consists of the assert id and debug data.

The notification may be divided to multiple chunks, depending
on the size of the debug data sent to the driver, which would
be up to 1KB.

Get the notification, and if the debug info flag is enabled,
print the debug data to the dmesg.

Subject: iwlwifi: remove unnecessary dev_cmd_headroom parameter

We don't need this parameter anymore, since we always pass 0 anyway.
Remove it from the structure and from all the relevant functions.

Subject: iwlwifi: pcie: introduce split point to a000 devices

a000 devices are going to have a lot of flows simplified
and changed: init flow, RX, TX, and more.
This, combined with the fact that code is already very
complicated due to backward compatibility - introduce
a split that will enable to introduce simplified version
of functions.
Shared ops are moved to a macro, while functions that will
be updated in the next patches are defined twice for now.

Subject: iwlwifi: pcie: add context information support

Context information structure is going to be used in a000
devices for firmware self init.

The self init includes firmware self loading from DRAM by
ROM.
This means the TFH relevant firmware loading can be cleaned up.

The firmware loading includes the paging memory as well, so op
mode can stop initializing the paging and sending the DRAM_BLOCK_CMD.

Firmware is doing RFH, TFH and SCD configuration, while driver
only fills the required configurations and addresses in the
context information structure.

The only remaining access to RFH is the write pointer, which
is updated upon alive interrupt after FW configured the RFH.

Subject: wil6210: support 8KB RX buffers

The 11ad spec requires 11ad devices to be able to receive 8KB
packets over the air. Currently this is only possible by
loading the driver with mtu_max=7912 but this also forces
a smaller block ACK window size which reduces performance
for stations which transmit normal sized packets (<2KB).
Fix this problem as follows:
1. Add a module parameter rx_large_buf that when set,
will allocate 8KB RX buffers regardless of mtu_max
setting.
2. When receiving block ACK request agree to any window
size not above our maximum, regardless of the mtu_max setting.
This means if the other side transmits small packets (2KB)
it can still set up block ACK with a large window size,
and get better performance.

Subject: wil6210: fix protection against connections during reset

Existing code that ignores connection events during
reset flow will never take effect since it locks the
same mutex taken by the reset flow.

In addition, in case of unsolicited disconnect events ignore
those as well since device is about to get reset.

Subject: wil6210: fix check for sparrow D0 FW file

Driver fails to load FW for sparrow D0 devices in some cases.
Fix this by returning correct value from wil_fw_verify_file_exists
when D0 FW file is not detected for any reason.

Subject: wil6210: fix memory access violation in wil_memcpy_from/toio_32

In case count is not multiple of 4, there is a read access in
wil_memcpy_toio_32() from outside src buffer boundary.
In wil_memcpy_fromio_32(), in case count is not multiple of 4, there is
a write access to outside dst io memory boundary.

Fix these issues with proper handling of the last 1 to 4 copied bytes.

Subject: wil6210: remove HALP voting in debugfs ioblob

debugfs ioblob function is called by the FW logs scripts
to copy the FW logs via PCIe.
As the FW logs collection is done in parallel to the operational
11AD actions, the HALP voting can take place during 11AD reset flow
and other sensitive scenarios.
To prevent that, remove HALP voting from the ioblob function.

Subject: wil6210: prevent access to 11AD device if resume fails

In case wil6210 resume fails, wil6210 suspend function will try
to access the suspended device in the next kernel suspend.
To prevent that, add wil_status_suspended flag to indicate if the
device is already suspended and clear it only if the resume succeeds.

Subject: brcmfmac: properly align buffers on certain platforms with 64 bit DMA

Systems with 64 bit DMA at least partially require buffers to be used
for DMA to be 8-byte-aligned. One example is Amlogic Meson GX.
Switching the MMC/SDIO driver for this platform to SG DMA mode
resulted in problems due to unaligned buffers.

Fortunately the brcmfmac driver has a global define for the alignment.
Changing it to 8 fixed the issues with Meson GX.

Subject: brcmfmac: ignore interfaces when fwsignal is disabled

When brcmf_fws_add_interface() is called the struct brcmf_if::fws_desc
field is initialized regardless the state of the fwsignal functionality,
ie. the fcmode. This is not needed when fcmode is NONE, which is the
default mode.

Subject: brcmfmac: remove reference to fwsignal data from struct brcmf_pub

The fwsignal module is part of the bcdc protocol and as such does
its instance data is not needed in core structure. Moving it into
struct brcmf_bcdc instead.

Assure the event data buffer is long enough to hold the array
of netinfo items and that SSID length does not exceed the maximum
of 32 characters as per 802.11 spec.

Subject: rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma
 duration

For time division multiple access, the wifi and bt take turns to
transmit, but we need to let AP know that wifi is under standby mode by
sending null data to "pretend" entering power saving state using lps
rpwm.

But, the fw does not know if it is the actual power saving mode or just a
fake one to cheat to the AP. Hence, before fw setting the tdma duration,
the fw needs the driver to check the power saving state first.

When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

Subject: rtlwifi: btcoex: 23b 2ant: check more cases when bt is queuing

If bt is queing, we need to set the packet priority properly.
Originally we only consider if wifi was connected or not, but now we
also consider if bt is under abnormal scan or wifi is scanning, roaming
or linking, and set the coex table.

During hw initialisation, wifi may be ready after bt has already been

When wifi is in concurrent mode, we can not distinguish if it is the
real PS or just a fake one by sending null data, so we turn it off
in case of miracast scenario.

Subject: rtlwifi: btcoex: 23b 2ant: turn off antenna when rssi is too high/low

For 2-antenna combo card, the signal of the neighbor antenna could be
over noise level and cause be severe interference. So we monitor the
rssi and turn off one of the antennas when the other is transmitting
and the rssi level is beyond a threshold.

To support miracast and P2P, the chip may operate under concurrent mode,
In this situation, do not aggregate tx packet and properly set the rx
aggregation size.

We detect it by monitoring the number of link established.

Subject: rtlwifi: btcoex: 21a 1ant: consider more cases when bt inquiry

With bt inquiry, the wifi may start as a softap or the wifi and bt are
busy, we take these scenarios into consider to avoid bt inquiry to
degrade the performance of the network

Subject: rtlwifi: btcoex: 21a 1ant: do not switch antenna when wifi is under

When wifi is on a 5G channel, the 5G signal will not interfere bt 2.4G
signal, and they can transmit simultaneously, hence there is no need to
switch antenna between wifi and bt.

Subject: rtlwifi: btcoex: 21a 1ant: avoid LPS/IPS mismatch for pnp notify

When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

Subject: rt2x00: reverse external PA capability flag logic

Consequently refer to external PA instead of inverting the logic and
use an internal PA capability flag which is a bit confusing.
Currently this is used for Rt3352 only, but MT7620A also allows for an
external PA which will be supported by a follow up patch.

Subject: ath10k: fix spectral scan for QCA99X0 family of chipsets

spectral_bin length (number of bins per fft sample) is usually
a value where (2^n = value), n is an integer.  All of the QCA99X0
family of chipsets seems to report a spectral_bin length of
2^n + 'm' bytes, where m = 4, 12 based on the chipset. This 'm'
bytes seems to carry some radar related info which is currently
discarded only for 'bin_len = 68' bytes. Extend this discarding of
irrelevant 'bin_len' for QCA9984, QCA9888, IPQ4019 as well by
introducing a hardware parameter 'spectral_bin_discard'. Also
for QCA988X based family of chipsets which doesn't seem to have this
issue and also for some of the hardware which I have not tested
like QCA6174/QCA9377 the existing behaviour is retained as it is.

Subject: ath10k: bump up FW API to 6

For QCA6174 hw3.0, since WLAN.RM.4.4-00022-QCARMSWPZ-2, it starts to
support the board ID information from otp, with some devices released on
the market that didn't calibrated with OTP, will have 0 for board ID
information, which cause the backward compatibility issue and was fixed
in commit 'd2e202c06ca4 ("ath10k: ignore configuring the incorrect board_id")'

So bump the fw api version to differentiate the latest firmware support.

Subject: ath9k: add noise floor override option

Introduce a debugfs option to manually override the noise floor,
ignoring the automatically tuned noise floor of the driver/hw.

In my tests with a AR9580 based module and a tx99 5 MHz interferer,
I could tune the noisefloor to -95 dBm or above to allow communication
again. The automatic noise floor calibration sometimes could adapt to
the situation as well, but not reliably and permanently.

I would consider this "feature" experimental and interesting for people
debugging the noise floor calibration or other effects of the hardware.

Subject: ath: Fix updating radar flags for coutry code India

As per latest regulatory update for India, channel 52, 56, 60, 64
is no longer restricted to DFS. Enabling DFS/no infra flags in driver
results in applying all DFS related restrictions (like doing CAC etc
before this channel moves to 'available state') for these channels
even though the country code is programmed as 'India' in he hardware,
fix this by relaxing the frequency range while applying RADAR flags
only if the country code is programmed to India. If the frequency range
needs to modified based on different country code, ath_is_radar_freq
can be extended/modified dynamically.

Subject: iwlwifi: mvm: add queues after adding station

Currently aux & broadcast queues are added before calling add
station, which results with a SCD_QUEUE_CFG command sent with
a station id unknown yet to fw.
While this works for pre-a000 firmware, the a000 fw requires
the order to be reversed.
The reason the change is only for a000 devices and not for
previous devices is that we cannot reverse the order since
the tfd_queue_mask containing the aux queue will cause FW to
assert on adding a queue mask with a queue that is not enabled.
This is not a problem in a000 fw since the tfd_queue_mask was
removed from the add sta API.

Subject: iwlwifi: mvm: prepare for station count change

In a000 devices we will support up to 32 stations.
The max station define is used also for invalid station marking
which makes finding usages of actual maximum station pretty hard
to sort through - change it to be a different define in order
to make future changes easier.
Use also ARRAY_SIZE intead of define when possible.
Do not move yet to 32 stations until firmware do it though.

Subject: iwlwifi: mvm: refactor SAR init to prepare for dynamic SAR

We are adding support for dynamic TX power tables for SAR (specific
absorption rate) compliance.  Currently, we only support a single
(static) TX power table, which is read from ACPI, and use it
statically.

To prepare for more tables that can be switched dynamically, refactor
the SAR init flow to allow reusage and add the current static table as
a single entry in an array of tables.

Subject: iwlwifi: mvm: spin off SAR profile selection function

For dynamic SAR, we will need to select the current profile from
different places.  In preparation for that, spin the profile selection
code out of iwl_mvm_sar_init().

Subject: iwlwifi: mvm: add support for EWRD (Dynamic SAR) ACPI table

Dynamic SAR allows changing TX power limits at runtime to comply with
SAR regulations on multiple form factors (e.g. tablet vs. clamshell
mode).  To support this, a new table was added to ACPI, which is
called Extended Wireless Regulatory Descriptor (EWRD).  This table
allows OEMs to define different TX power profiles for each form-factor
or usage mode.

Read this new table and store it in our SAR profiles table, in
preparation for Dynamic SAR support.

Subject: iwlwifi: mvm: support new TX API

Support the new TX command API for a000 devices.
Command is a very slim version of current TX command.
Generalize iwl_mvm_tx_mpdu to get rid of TX command dependencies.

Subject: iwlwifi: pcie: introduce a000 TX queues management

In a000 devices the TX handling is different in a few ways:
* Queues are allocated dynamically
* DQA is enabled by default
* Driver shouldn't access TFH registers - ucode configures it
  all in SCD_QUEUE_CFG command

Support all this in a new API with op mode, where op mode sends
the command, transport will allocate the queue dynamically, fill
in DMA properties, send the command to FW and get the ID back.
Current implementation only sets the new transport API and fills
the DMA properties.
Future patches will complete the other parts.

From bb49701b41deff0a8edd297357b23ffe833099eb Mon Sep 17 00:00:00 2001

Subject: iwlwifi: mvm: support a000 SCD queue configuration

a000 devices queue management is going to change significantly.
We will have 512 queues. Those queues will be assigned number
by the firmware and not by the driver.

In addition, due to SN offload having TX queue shared between TIDs
is impossible

Also, the ADD_STA command no longer updates queues status.
The only point of changing queue in the SCD queue config API.

From driver perspective we have here a new design:

Queue sharing and inactivity checks are disabled.

Once this is done, the only paths that call scd_queue_cfg command
are paths that alloc and release TX queues - which will make future
accommodation to queue number assignment by FW easier.
Since allocating 512 queues statically is not advisable, transport
will allocate the queue on demand, fill the command with DRAM data
and send it. This is reflected in the new transport API.

Subject: iwlwifi: mvm: support moving to mgmt tid

For a000 FW moved to 15 as management TID.
The change for us is fairly local - translate old TID to 15
when enabling and disabling a queue, and make sure to cover
it also on TX responses.

Subject: iwlwifi: mvm: remove unnecessary debugging from UMAC scan

There are several occasions where a scan of the same type is requested
concurrently, so logging every time this happens is just noisy and
unnecessary.  Remove the logging for these cases.

Subject: iwlwifi: mvm: tell the firmware about the U-APSD parameters

Newer firmware versions will be able to handle all the
WMM-PS flows internally when we act as a GO. The firwmare
relies on the fact that the drivers puts frames for
different peers in different queues (DQA) to achieve this.
The driver will not be aware of the power state of the peers
anymore.

Tell the firmware about the WMM-PS parameters of earch peer
that connects to us so that it can know what are the
trigger-enabled ACs, the delivery-enableds ACs and the
Service Period length.

This API change is backward compatible since older firmware
versions will simply ignore the newly added values.

Since we don't support ieee80211 TSPECs for now, just copy
the trigger-enabled ACs to the delivery enabled ones.

Subject: iwlwifi: pcie: support host commands in new transport

Code is basically the same, with a cleanups of old narrow host
command, ampg workarounds, some cosmetic stuff, and usage of
TFH functions when accessing TFD queues.
This enables also the cleanup of iwl_pcie_tfd_set_tb() since
now it won't be called anywhere in the a000 data path

Subject: iwlwifi: pcie: prepare for dynamic queue allocation

In a000 transport we will allocate queues dynamically.
Right now queue are allocated as one big chunk of memory
and accessed as such.
The dynamic allocation of the queues will require accessing
the queues as pointers.
In order to keep simplicity of pre-a000 tx queues handling,
keep allocating and freeing the memory in the same style,
but move to access the queues in the various functions as
individual pointers.
Dynamic allocation for the a000 devices will be in a separate
patch.

Subject: iwlwifi: pcie: introduce new stop_device

This function is basically the same as gen1, except for clean
ups of old devices configuration that are never used in a000
configuration.
It will also help with refactoring rf_kill later on.

Subject: iwlwifi: pcie: alloc queues dynamically

Change queue allocation to be dynamic. On transport init only
the command queue is being allocated. Other queues are allocated
on demand.
This is due to the huge amount of queues we will soon enable (512)
and as a preparation for TX Virtual Queue Manager feature (TVQM),
where firmware will assign the actual queue number on demand.
This includes also allocation of the byte count table per queue
and not as a contiguous chunk of memory.

Subject: iwlwifi: mvm: support new TX response for TVQM

In TVQM mode the TX responses were changed to include
queue number since legacy TX queue number retrieval cannot
be scaled up to 512 queues.
Support this change.

Subject: iwlwifi: move to TVQM mode

In TVQM firmware returns the value of the queue ID and code
should accept it.
The TX queue config API was changed. Move to new API.
This has to be done in parallel in mvm and pcie.
Do not move yet to 512 queues since there are some opens
with enabling it.

Subject: iwlwifi: mvm: remove unneeded reg write in iwl_mvm_up()

Not only that this write is not needed (as FW does this
itself), on newer HW this register is write protected
so trying to write there will cause problems.

ourselves, turning it on is misleading and pointless.

Subject: iwlwifi: mvm: work around HW issue with AMSDU de-aggregation

Seems like HW is reversing addr3 in the MAC header of de-aggregated
AMSDU. Reverse it back.

Subject: iwlwifi: mvm: ignore BAID for SN smaller than SSN

When we get SN that is smaller than SSN of the aggregation,
we shouldn't apply any reordering on them.
Further more, HW NSSN will be zeroed, which can cause us
to make some invalid decisions.
Detect the situation and invalidate the BAID.

Subject: iwlwifi: mvm: add GEO_TX_POWER_LIMIT cmd for geographic tx power
 table

To utilize the maximum allowed tx power, an additional table was added
to the BIOS. The table consists of up to seven different regions
(currently only three are in use). Each region contains per band:
1. Maximum allowed tx power on the band.
2. Tx power offset for chain A.
3. Tx power offset for chain B.
On init flow driver reads this table by means of ACPI and
passes it to the firmware with GEO_TX_POWER_LIMIT cmd.
The firmware will use this table to enhance tx power with
the offset in the relevant table as well as verifying it does not
violate the maximum allowed tx power.

Subject: iwlwifi: mvm: support init extended command

When we load firmware in extended mode (as we do by default for
now) driver should send a command what kind of commands ucode
should stop and wait for before proceeding with phy calibrations.
Support this command. Currently we only do NVM access - so mark
this bit only.

Subject: iwlwifi: mvm: dump frames early on invalid rate

Currently when rate isn't found (invalid rate or CCK rate in high
band) driver is assigning rate -1, which causes mac80211 to dump
it later with the cryptic rate value of 0xFF.
Instead, warn early and dump the frame in mvm.

Subject: iwlwifi: split the handler and the wake parts of the notification
 infra

The notification infrastructure (iwl_notification_wait_*
functions) allows to wait until a list of notifications
will come up from the firmware and to run a special handler
(notif_wait handler) when those are received.

The operation mode notifies the notification infrastructure
about any Rx being received by the mean of
iwl_notification_wait_notify() which will do two things:
1) call the notif_wait handler
2) wakeup the thread that was waiting for the notification

Typically, only after those two steps happened, the
operation mode will run its own handler for the notification
that was received from the firmware. This means that the
thread that was waiting for that notification can be
running before the operation mode's handler was called.

When the operation mode's handler is ASYNC, things get even
worse since the thread that was waiting for the
notification isn't even guaranteed that the ASYNC callback
was added to async_handlers_list before it starts to run.
This means that even calling
iwl_mvm_wait_for_async_handlers() can't guarantee that
absolutely everything related to that notification has run.
The following can happen:

Thread sending the command        Operation mode's Rx path
--------------------------        ------------------------
iwl_init_notification_wait()
iwl_mvm_send_cmd()
                                  iwl_mvm_rx_common()
                                  iwl_notification_wait_notify()
iwl_mvm_wait_for_async_handlers()
// Possibly free some data
// structure
                                  list_add_tail(async_handlers_list);
                                  schedule_work(async_handlers_wk);
                                  // Access the freed structure

Split the 'run notif_wait's handler' and the 'wake up the
thread' parts to fix this. This allows the operation mode
to do the following:

Thread sending the command        Operation mode's Rx path
--------------------------        ------------------------
iwl_init_notification_wait()
iwl_mvm_send_cmd()
                                  iwl_mvm_rx_common()
                                  iwl_notification_wait()
                                  // Will run the notif_wait's handler
                                  list_add_tail(async_handlers_list);
                                  schedule_work(async_handlers_wk);
                                  iwl_notification_notify()
iwl_mvm_wait_for_async_handlers()

This way, the waiter is guaranteed that all the handlers
have been run (if SYNC), or at least enqueued (if ASYNC)
by the time it wakes up.

Subject: mwifiex: MAC randomization should not be persistent

nl80211 provides the NL80211_SCAN_FLAG_RANDOM_ADDR for every scan
request that should be randomized; the absence of such a flag means we
should not randomize. However, mwifiex was stashing the latest
randomization request and *always* using it for future scans, even those
that didn't set the flag.

Let's zero out the randomization info whenever we get a scan request
without NL80211_SCAN_FLAG_RANDOM_ADDR. I'd prefer to remove
priv->random_mac entirely (and plumb the randomization MAC properly
through the call sequence), but the spaghetti is a little difficult to
unravel here for me.

Subject: mwifiex: pcie: extract wifi part from combo firmware during function
 level reset

A separate wifi-only firmware was download during pcie function level
reset. It is in fact the tail part of wifi/bt combo firmware. Per
Brian's and Dmitry's suggestion, this patch extract the wifi part from
combo firmware.

After that, the mrvl/pcie8997_wlan_v4.bin image in linux-firmware repo
is redundant (though I guess we keep it around to support older
kernels).

Subject: mwifiex: pcie: fix cmd_buf use-after-free in remove/reset

Command buffers (skb's) are allocated by the main driver, and freed upon
the last use. That last use is often in mwifiex_free_cmd_buffer(). In
the meantime, if the command buffer gets used by the PCI driver, we map
it as DMA-able, and store the mapping information in the 'cb' memory.

However, if a command was in-flight when resetting the device (and
therefore was still mapped), we don't get a chance to unmap this memory
until after the core has cleaned up its command handling.

Let's keep a refcount within the PCI driver, so we ensure the memory
only gets freed after we've finished unmapping it.

Noticed by KASAN when forcing a reset via:

  echo 1 > /sys/bus/pci/.../reset

The same code path can presumably be exercised in remove() and
shutdown().

noticed in commit 955ab095c51a ("mwifiex: Do not kfree cmd buf while
unregistering PCIe"), but it just fixed the double-free, without
acknowledging the potential for use-after-free.

Subject: mwifiex: reset timeout flag when resetting device

If we reset because of a command timeout, we should reset this flag.
Otherwise, we might erroneously think the next command after reset is
timing out, and trigger another reset.

The above behavior effectively neuters the automatic card_reset()
behavior, as it means we will never recover from a command timeout
properly (and in fact, we might enter an infinite loop:

  timeout -> reset -> (fake) timeout -> reset -> ...

This fixes a bug introduced with introduction of PCIe function level
reset support, but it was carried into the SDIO driver when it was
converted to use the same codepaths. And this is currently mostly a
problem only in the SDIO driver, because it's the only one with
automatic card_reset() support (e.g., on command timeout). But it will
be a problem for PCIe too, as I'm working on supporting automatic
card_reset() for PCIe.

Subject: mwifiex: pcie: clear outstanding work when resetting

When we shut down the device (i.e., during 'reset'), we cancel any
outstanding work, but we don't clear any work-related flags. This can
cause problems if, e.g., we begin to queue a new firmware dump or card
reset while the other one is in progress. That might leave work_flags
with a stale value, and we might begin one of these *after* we've
completely reset the device. That doesn't make sense, because all
firmware context will have been lost by then.

This fixes some forms of cascading failures, where I:

(a) force a firmware dump (cat /sys/kernel/debug/mwifiex/mlan0/device_dump)
(b) run a Wifi scan in parallel (iw mlan0 scan)
(c) the scan times out due to (a) hogging the interface
(d) the command timeout triggers another firmware dump and a reset [*]
(e) the 2nd firmware dump flag persists across the reset
(f) as soon as the interface comes back up, we trigger the pending
    firmware dump
(g) subsequent commands time out again, while we are processing the
    firmware dump; return to (d)

[*] Note that automatic card_reset() support is not yet implemented for
the mwifiex PCIe driver, so we won't hit *exactly* this behavior yet.
But we can see similarly-confusing behaviors today.

Subject: mwifiex: don't leak 'chan_stats' on reset

'chan_stats' is (re)allocated in _mwifiex_fw_dpc() ->
mwifiex_init_channel_scan_gap(), which is called whenever the device is
initialized -- at probe or at reset.

But we only free it in we completely unregister the adapter, meaning we
leak a copy of it during every reset.

Let's free it in the shutdown / removal paths instead (and in the
error-handling path), to avoid the leak.

Ideally, we can eventually unify much of mwifiex_shutdown_sw() and
mwifiex_remove_card() (way too much copy-and-paste) to reduce the burden
on bugfixes like this. But that's work for tomorrow.

We monitor the packet counter to guess if the bt is slave or not, and
when bt is slave, it may receive packet at any time, so we will have to

Subject: rtlwifi: btcoex: 21a 2ant: monitor wifi counter to check network
 status

If there are a lot of low-rate packets, then the connection of wifi is
unstable. If so, we should switch resource to bt to have a higher
transmission quality, or wifi resource will be wasted

Subject: rtlwifi: btcoex: 21a 2ant: finer adjustment of bt power

Originally we only increase/decrease bt power in a fixed power gap, this
patch makes us be able to modify bt power for multiple power gaps and we
can precisely adjust the bt power.

Subject: rtlwifi: btcoex: 21a 2ant: check power save state before pstdma

The power_save_state function checks the state of power saving.
For tdma settings, the wifi sends nullfunc to pretend enter power saving
and then bt can transmit. Hence the coex needs to check the power status
before set the pstdma function.

Subject: rtlwifi: btcoex: 21a 2ant: ignore wifi if it is at 5G band

When wifi is at 5G band, it does not intefere with 2.4G bt signal,
hence we can just ignore it and transmit normally as nothing happened.

Subject: rtlwifi: btcoex: 21a 2ant: set coex table and tdma when bt inquiry

Instead of just setting the coex table directly, we check if the
wifi is under some important activity (scanning|roaming|linking) and
mark the packets as high priority in that case.

Subject: rtlwifi: btcoex: 21a 2ant: action for wifi is idle/linking/common

Depending on the state of wifi, we need to set different tdma and coex
table parameters to make wfi and bt coexist smoothly. Otherwise the
bt may have low sound quality or mouse lag, which mean bad user
experience. The same problem may occur on wifi also, if could disconnect
or lose some important packets.

Subject: rtlwifi: btcoex: 21a 2ant: refine tdma duration adjust function

1. Add more cases to adjust the wifi duration and add a case with
the max interval of 3 for some future uses.

2. rename tdma_adj -> ps_tdma_du_adj to indicate that this member is
for power saving tdma duration adjustment

Subject: rtlwifi: btcoex: 21a 2ant: add multiport action for p2p/miracast

For p2p/miracast, the wifi may have multiple ports for different roles.
Under this, we need extra settings for turning off the tdma and proper
coex table parameters.

We monnitor the number of links on a port to determine if it is for
p2p/miracast or not.

Subject: rtlwifi: btcoex: 21a 2ant: wifi is linking action

When wifi is under scanning/linking/roaming, do not run the reset of the
coex mechanism because these activities are important for wifi, just run
the linking process and return.

Subject: rt2800: fix LNA gain assignment for MT7620

The base value used for MT7620 differs from Rt5392 which resulted in
quite bad RX signal quality. Fix this by using the correct base value as
well as the LNA calibration values for HT20.

Subject: rt2800: do VCO calibration after programming ALC

Somehow AP doesn't come up and the first scan fails if we don't do
VCO calibration every time.
The vendor driver duplicates the VCO calibration function into the
channel switching logic, we can do the same with less duplication.

Use register values from init LNA function instead of the ones from
restore LNA function. Apply register values based on rx path
configuration.
