QCA6164 in Fedora

QCA6164 in Fedora

[Susi Lehtola]

Hello people,


I recently bought a Lenovo U31 laptop for work, and was surprised 
wireless didn't work out of the box.

Fortunately thanks to you the card (supposedly) works in linux, but I 
have yet to get mine to work.

I've patched the Fedora 4.1.6 kernel
  https://bugzilla.redhat.com/attachment.cgi?id=1069561&action=diff
to add support for the card, which I adapted from
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436940

However, I'm having trouble loading the firmware. I took the firmware 
files from
 
https://github.com/atondwal/ath10k-firmware/commit/88fca85ef59d708b9874e5b7885416b58aef9ee7
and installed them into /lib/firmware/ath10k/QCA6174/hw2.1/, renaming 
firmare-5.bin to firmware-4.bin.

I also have added the necessary kernel option

$ cat /etc/modprobe.d/ath10k.conf
options ath10k_core skip_otp=y

After these changes, the kernel does detect the card, but it fails to 
load the firmware.

The card in question is

(rev 20)

What might be the problem?

FYI This is asking for problems. You can't just go around renaming
firmware files like that. There's a reason why there are different
numbers in the filename.

You're surely using wrong board.bin. The qca6164 will not work with
the board.bin for qca6174.

The board.bin problem is currently being addressed. In the meantime
you need to get an adequate eeprom_* file from windows driver and put
it as hw2.1/board.bin. You'll need to look into .inf file from the
windows driver and output of `lspci -vvnn` to understand which eeprom
file suits your device.

I can confirm the card works with the linux-next tree, using a snapshot 
I took today.

However, it would be nice to get this working in the 4.1.6 kernel which 
supposedly supports the 6174 chip.

The problem in the Fedora kernel is that the direct firmware load fails, 
althoug the same firmware works with the linux-next tree.

What would need to be backported to the 4.1 tree in order to get the 
card working?

However, the card only seems to make a 1Mbps connection in the same 
situation where my old laptop made a 55Mbps one...

You need to cherry-pick at least this patch:
https://github.com/kvalo/ath/commit/36582e5d4daeccf68a8a3cef9bc37b60fb7d45b9

The problem is qca6164 requires a different board.bin and will not
work with one from qca6174. The driver uses the same firmware filepath
for both. There's a per-pci-vid/pid board lookup but it's broken I
would discourage using it until we come up with a better solution.

How did you measure this? `iw` tool reports invalid tx bitrate for
ath10k due to firmware limitation. Did you test the actual performance
(iperf/wget)? Is it downlink or uplink? Are both as bad?

This was the link speed reported by NetworkManager. But yes, actual 
performance is much better, seeing 2.2 MB/sec is not uncommon [the 
internet connection is pretty slow].

I tried that but it didn't work; the card was detected but the firmware 
failed to load. The patch I formed is at
https://bugzilla.redhat.com/attachment.cgi?id=1069561

The exact same firmware and board.bin works with the linux-next tree.

However, now that the development version of Fedora comes with kernel 
4.3, I can just recompile the package for my laptop. This problem should 
solve itself with time..
