After processing received packets from copy engine, host will allocate
new buffer and queue them back to copy engine ring for further
packet reception. On post rx processing path, skb allocation and
dma mapping are unnecessarily handled within ce_lock. This is affecting
peak throughput and also causing more CPU consumption. Optimize this
by acquiring ce_lock only when accessing copy engine ring and moving
skb allocation out of ce_lock.
In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak
throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak
throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps
(71% CPU load). Similarly ~40Mbps improvement is observed in downlink

when all it needs is a boolean pointer.
It would be better to update this API to make it accept 'bool *'
instead, as that will make it more consistent and often more convenient.
Over that bool takes just a byte.
That required updates to all user sites as well, in the same commit

PRI value is used as divider when DFS detector analyzes candidate
radar pulses.
If PRI deviation is big from its origin PRI, DFS detector could miss
valid radar reports since HW often misses detecting radar pulses and
causes long interval value of pulses.
For instance from practical results, if runtime PRI is calculated as
1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
the modular remainder will be 1409 and the delta between the remainder
and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
As a result this radar report will be ignored even though it's valid.
By using spec defined PRI for fixed PRI, we can correct this error.

Current kernel support only one fw name with theoretically only one

have only one fw version (1.3). After we realised new fw 1.4, we faced
compatibility problem which was decided to solve by firmware name and
location:
- new firmware is located now in
firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw
- old version 1.3 should be on old place, so old kernel have no issues
with it.
- new kernels including this patch should be able to try different
supported (min..max) fw version.
- new kernel should be able to support old fw location too. At least for
now.
At same time this patch will add new module option which should allow user
to play with development fw version without replacing stable one. If user
will set “ath9k_htc use_dev_fw=1” module will try to find
firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use

Add support for mesh to ath10k. We simply use an AP virtual interface
in the firmware in order to enable beaconing without TSF adoption, and
use the raw (802.11) transmit mode.
Due to firmware limitations, the firmware must operate in raw
(non-native 802.11) mode. As this is configured at firmware init time,
a new "rawmode" modparam is added, and mesh interfaces are available
only if rawmode=true. The firmware must advertise support for rawmode;
tested successfully with firmware 10.2.4.70.6-2.
When the module is loaded with (newly implemented) modparam rawmode=1, it
will enable operating an open mesh STA via something like the following:
ip link set wlan0 down
iw dev wlan0 set type mp
ip link set wlan0 up
iw dev wlan0 set freq 5745 80 5775

During long hours of stress testing like AP interface up/down along
with continuous ping flood from a station doing connect/disconnect,
it is observed that the system is not able to allocate DMA consistent
memory of size > 512KB chunks as requested by firmware in WMI_SERVICE_EVENTID.
With the system memory getting fragmented during the run based on the
size of the memory requested, the failure to return physically continguous
memory of high order can happen. Once the system gets to this situation,
bringing up the wifi interface will fail and a system reboot may be needed
to make it work again. This problem is obseved with QCA99X0.
To fix this issue, allocate the DMA memory requested by firmware during
device probe time and keep it during the life time of the device. WMI service
ready event handler is changed to allocate the memory chunks if it is
not already allocated or if the memory allocated for the previous ready
event is not same as the current requested ones. After this patch the
memory usage when wifi is inactive will be inceased by few 100KB to
3MB based on the target type.

MU-MIMO Rx involves different interpretation of
the VHT-SIG-A compared to SU-MIMO.
The incorrect interpretation led ath10k to report
VHT MCS values greater than 9 which subsequently
prompted mac80211 to drop such frames. This
effectively broke Rx with MU-MIMO in many cases
and manifested with a kernel warning in the log

This adds additional 0x0041 PCI Device ID
definition to ath10k for QCA6164 which is a 1
spatial stream sibling of the QCA6174 (which is 2
spatial stream chip).
The QCA6164 needs a dedicated board.bin file which
is different than the one used for QCA6174. If the
board.bin is wrong the device will crash early
while trying to boot firmware. The register dump
will look like this:

To enable/configure spectral scan parameters in 10.4 firmware, existing
wmi spectral related functions can be reused. Link those functions in
10.4 wmi ops table.
In addition, adjust bin size (only when size is 68 bytes) before reporting
bin samples to user space. The background for this adjustment is that
qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
carries band edge detection data (+32) mainly used in radar detection
purpose. Additional last 4 bytes are stripped to make bin size valid one.
This bin size adjustment will happen only for qca99x0, all other chipsets
will report proper bin sizes (64/128) without extra 4 bytes being added
at the end. The changes are validated in qca99x0 using 10.4 firmware.

Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.
Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.
.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.
Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

There are three WMI_CHAN_INFO events reported per channel
in QCA99X0 firmware. First one is a notification at the begining
of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
second one is a notification at the end of the dwell time with cmd_flag
CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
the channel. Since there is a new state before the completion, the handler
is to fixed so that the counts are deducted from the ones reported with

Vif's vdev_id is used as queue number. However due
to the tx pausing design in ath10k it was possible
for a new interface to be created with its tx
queue stopped (via ieee80211_stop_queues). This
could in turn leave the interface inoperable until
ath10k_mac_tx_unlock() was called.
This problem only affected multi-vif scenarios when
new interfaces were created some time later after
other interfaces have been running for some time
and had Tx queue full at some point prior.
Possible manifestation of the bug was
authentication timeout for a client vif.

Even though there's a WMI enum for fragmentation
threshold no known firmware actually implements
it. Moreover it is not possible to rely frame
fragmentation to mac80211 because firmware clears
the "more fragments" bit in frame control making
it impossible for remote devices to reassemble
frames.
Hence implement a dummy callback just to say
fragmentation isn't supported. This effectively
prevents mac80211 from doing frame fragmentation
in software.
This fixes Tx becoming broken after setting
fragmentation threshold.

Allow network stack part of Rx processing to run on separate core,
relaxing CPU utilization on the core used for Rx NAPI.
If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
to enable RPS. The core for processing the rx skb is determined by RPS
mechanism according to rx_cpus bit mask which is configured at user level.
For processing skbs on different core from the core which processes
the interrupts, it is recommended not to enable core 0 in rx_cpus bit mask.

Initial QCA99X0 support has a known issue with TCP Tx throughput.
All other path such as UDP Tx/Rx and TCP Rx meet their expectation
(> 900Mbps), but TCP Tx marked as low as 5Mbps when single pair is
used on iperf.
The root cause is turned out because TSO flag is not initialized
properly so that firmware configures TSO in wrong way.
TSO flags in msdu extension descriptor is required to be reset
to indicate firmware there is no TSO is enabled, otherwise it
could act as TSO is enabled which causes huge throughput drop.
In fact, it's enough by resetting TSO flags only to prevent the
unexpected behavior, but initializing whole msdu ext. descriptor
will help to clear uncertainty of firmware could bring on as it
constantly updated.

Host memory required for firmware is allocated while handling
wmi service ready event. Right now, wmi service ready is handled
in tasklet context and it calls dma_alloc_coherent() with atomic
flag (GFP_ATOMIC) to allocate memory in host needed for firmware.
The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in
the platform (at least in AP platform) where it has less atomic
pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory
for one card, having additional QCA99X0 card in the same platform
will require similarly amount of memory. So, it's not guaranteed that
all the platform will have enough atomic memory pool.
Fix this issue, by handling wmi service ready event in workqueue
context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work
queue will not be ready at the time of handling wmi service ready.
So, it can't be used to handle wmi service ready. Also, register work
gets scheduled during insmod in existing ath10k_wq and waits for
wmi service ready to completed. Both workqueue can't be used for
this purpose. New auxiliary workqueue is added to handle wmi service
ready.

This patch enables raw Rx/Tx encap mode to support software based
crypto engine. This patch introduces a new module param 'cryptmode'.
cryptmode:
0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
encapsulation to the firmware. This is the default mode.
1: Use sofware crypto engine globally with raw mode TX/RX
encapsulation to the firmware.
Known limitation:
A-MSDU must be disabled for RAW Tx encap mode to perform well when
heavy traffic is applied.

When using DFS channels on Ath10k, kernel log has repeated warning message
'failed to process fft: -22' typically under medium/heavy traffic.
This patch switches the warnings to driver debug (WMI events) mode only
thus reducing log file noise.
DFS and spectral scan share underlying HW mechanisms and enabling one
(DFS) enables the other (spectral scan) as far as event reporting from
firmware to driver is concerned. Spectral scan events take no part in
processing of DFS radar pulses which are delivered as distinct events,
so the fft (spectral event) warning is harmless and DFS interference
detection/protection still occurs.

HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
rate mgmt frame has to go out in the air. It's an optional parameter,
setting this field to zero will force firmware to choose auto rate
and send the frame out.
Those 4 byte info is missed out in the current code and 10.4 firmware
ended up reading some junk in those 4 byte and sometime malfunctioning.
Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
will not process those four byte. So, adding 4 byte at the end of
struct htt_mgmt_tx_desc will not create any impact on other chipset.

Data Bus Error and system hard lockup. The reason
for bus error is that pcie needs some time to get
back to stable state for any transaction during cold reset. Add
delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
to fix this issue. This patch is tested on QCA988X. This is
also tested on QCA99X0 which is WIP.

We measured the FFT-based entropy in 3 ways, Shannon entropy,
collision entropy, and directly measured min-entropy. Just to
be conservative, we recommend the estimated min-Entropy to be
10 bits per 16-bit value.

While compiling ath9k with some extra flags I've
found that:
ath9k/xmit.c +2473 ## 16: warning: restricted __le16 degrades to integer
ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &=
ath9k/xmit.c +2474 ## 36: left side has type restricted __le16
ath9k/xmit.c +2474 ## 36: right side has type int
There's no way for frame ftype/stype to be
mistreated as the offending 'moredata' flag when
considering cab queue.
This could've however theoretically led sometimes
to increased power consumption on connected
stations as they would keep their Rx active
waiting for frames that would never come.

A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.
Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.
To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.

FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.
A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range
The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

Whenever any vdev was supposed to be paused all Tx
queues were stopped (except offchannel) instead of
only these associated with the given vdev.
This caused subtle issues with
multi-channel/multi-vif scenarios, e.g.
authentication of station vif could sometimes fail
depending on fw tx pause request timing.

Further testing proved that multi-channel AP+STA
on QCA6174 with RM.2.0-00088 should have powersave
force-disabled to avoid beacon misses/skipping on
either side which in turn could disrupt
communication.
Since AP never has arvif->ps don't even bother
checking it. Other combinations may be broken as
well so disallow powersave with multivif outright
unless firmware advertises otherwise.

Pre qca99X0 chipsets follows the model where dynamically allocate
memory for frag desc on getting new skb for TX. But, this is not
going to be the case in qca99X0. It expects frag desc memory to be
allocated at boot time and let the driver to reuse allocated memory
after every TX completion. So there won't be any dynamic frag memory
memory allocation in qca99X0 during data transmission.
qca99X0 hardware doesn't need fragment desc address to be programmed
in msdu descriptor for every data transaction. It needs to know only
starting address of fragment descriptor at the time of the boot.
During data transmission, qca99X0 hardware can retrieve corresponding
frag addr by adding programmed frag desc base addr + msdu id.
Allocate continuous fragment descriptor memory (same size as number of
descriptor) at the time of target initialization and configure allocated
dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.
How this is allocated continuous memory is going to be used is not
covered in this patch. It just allocates memory and hand over to firmware.
If we don't do it at init time, qca99X0 will stall when firmware tries
to do TX.
