Rajkumar Manoharan 7a1d70ab05 ath10k: fill HT/VHT MCS rateset only for configured chainmask
HT/VHT MCS rateset should be filled only for configured chainmask
rather that max supported chainmask. Fix that by checking configured
chainmask while filling HT/VHT MCS rate map.

Rajkumar Manoharan b4c306d0c5 ath10k: remove shadow copy of CE descriptors for source ring
For the messages from host to target, shadow copy of CE descriptors
are maintained in source ring. Before writing actual CE descriptor,
first shadow copy is filled and then it is copied to CE address space.
To optimize in download path and to reduce d-cache pressure, removing
shadow copy of CE descriptors. This will also reduce driver memory
consumption by 33KB during on device probing.

Rajkumar Manoharan 765952e40d ath10k: cleanup copy engine send completion
The physical address necessary to unmap DMA ('bufferp') is stored
in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
when handling send completion (htc ep id is stored in sk_buff control
buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp}
are removed from CE send completion. This change is needed before removing
the shadow copy of copy engine (CE) descriptors in follow up patch.

Rajkumar Manoharan b4e84c5606 ath10k: use local memory instead of shadow descriptor in ce_send
Currently to avoid uncached memory access while filling up copy engine
descriptors, shadow descriptors are used. This can be optimized further
by removing shadow descriptors. To achieve that first shadow ring
dependency in ce_send is removed by creating local copy of the
descriptor on stack and make a one-shot copy into the "uncached"
descriptor.

Maharaja 62f77f095c ath10k: enable adaptive CCA
European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.

Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.

The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

I'm planning to create similar directories for all vendors, currently we
just have ath, mediatek and realtek. This change has been in linux-next

There's also a new driver rtl8xxxu for few realtek USB devices. This
just made it to the last linux-next build.

Otherwise there's nothing really special, more info below. If time

Anilkumar Kolli 1aaf8efba0 ath10k: disable PCI PS for QCA988X and QCA99X0
This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is
validated for QCA6174, let it be enabled only for QCA6174. It would be
better to execute PCI PS related functions only for the supported devices.

PCI time out issue is observed with QCA99X0 on x86 platform, We will
disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly implemented.

Taking and releasing ps_lock is causing higher CPU consumption. Michal Kazior
suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep
functions are called less often, i.e. move the powersave logic up (only during
irq handling, tx path, submitting fw commands) but that's a bigger change and
can be implemented later.

Rajkumar Manoharan a70587b338 ath10k: configure copy engine 5 for HTT messages
Currently target to host (T2H) HTT messages are received at copy engine 1.
These messages are processed by HTC layer in both host and target.
To avoid HTC level processing overhead in both host and target,
the unused copy engine 5 is being used for receiving HTT T2H messages.
This will speedup the receive data processing as well as htt tx completion.
Hence host and target copy engine configuration tables are updated
to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5
for all HTT T2H.

Moreover HTT send completion messages are polled from HTC handler
as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling
needs to be done whenever CE pipe which transports HTT Rx (target->host)
is processed. This avoids overhead of polling HTT messages from HTC
layer. Servicing CE 4 faster is helping to solve "failed to transmit
packet, dropping: -105".

Manikanta Pubbisetty 0a51b343ab ath10k: add board 2 API support
QCA6174 needs different board files based on board type. To make it easier to
distribute multiple board files and automatically choose correct board file
create a simple TLV file format following the same principles as with FW IEs.
The file is named board-2.bin and contain multiple board files. Each board file
then can have multiple names.

ath10k searches for file board-N.bin (where N is the interface version number
for the board file, just like we for firmware files) in /lib/firmware/*, for
example for qca99x0 it will try to find it here:

/lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin

If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file.

This patch adds a simple name scheme using pci device id which for now will be
used by qca6174:

bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x

This removes the old method of having subsystem ids in ar->spec_board_id and
using that in the board file name.

Rajkumar Manoharan ab4e3db043 ath10k: optimize ce_lock on post rx buffer processing
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
path.

Felix Fietkau 76d164f582 ath10k: fix DMA related firmware crashes on multiple devices
Some platforms really don't like DMA bursts of 256 bytes, and this
causes the firmware to crash when sending beacons.
Also, changing this based on the firmware version does not seem to make
much sense, so use 128 bytes for all versions.

Michal Kazior 634349bae0 ath10k: move hw_scan worker queuing
The remain_on_channel callback needs different
timeout. Calling ieee80211_queue_work() with a
shorter delay after calling it with a longer delay
will not change the timer. This caused the
offchannel timeout worker to not trigger in time
and caused the device to stay on channel longer
then expected. This could cause some problems and
was be easily reproduced with `iw offchannel`
command.

Bob Copeland b6c7bafa7d ath10k: implement mesh support
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
    iw dev wlan0 mesh join mesh-vht
