Well, if it can also d

the maximum tx / rx rate for 4x4 vht80 and 2x2 vht160 is identical. so

From: Ben Greear
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 sp

Both, as I understand it. I think maybe we could use the max-tx-rate and
max-rx-rate
fields in the vht mcs info field to give user-space a clue.
Thanks,

So, it appears that the ath10k QCA9984 4x4 160Mhz chip can do 4x4 MIMO at
VHT80, but
it can do only 2x2 MIMO at VHT160/80+80.
When configuring a peer, we need to tell the firmware the number of spatial

The variant[] string will be valid only if the bdf_ext is set.
The string memory needs to be null-terminated to avoid the undefined garbage

From looking at firmware, it appears the driver needs to set
peer_bw_rxnss_override,
but it is not set in the 4.9 driver.
Has anyone investigated this already?
Thanks,

Hi,
here are patches to make ath10k less spammy during initialisation.
v2:
* RFC -> PATCH
* add new patches:
ath10k: fetch firmware images in a loop
ath10k: add directory to board data error message
ath10k: convert warning about non-existent OTP board id to debug message

From: Michal Kazior
Firmware files are versioned to prevent older
driver instances to load unsupported firmware
blobs. This is reflected with a fallback logic
which attempts to load several firmware files.
This however produced a lot of unnecessary
warnings sometimes confusing users and leading
Currently ath10k unncessarily warns about board id not available from OTP:
ath10k_pci :02:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0
ath10k_pci :02:00.0: qca988x hw2.0 target 0x4100016c chip_id 0x043202ff sub
:
ath10k_pci :02:00.0: kconfig debug 1 debugfs 1 trac
This way user has a better idea what file exactly is missing.
This is needed when we switch to using request_firmware_direct() which doesn't
print any errors anymore.

This fixes the below crash when ath10k probe firmware fails, NAPI polling tries
to access a rx ring resource which was never allocated. An easy way to
reproduce this is easy to remove all the firmware files, load ath10k modules
and ath10k will crash when calling 'rmmod ath10k_pci'. The fix is to ca

Nevermind, I was blind again. It was my script which calls rmmod and I
failed to realise that. Sorry
