Does anyone know what would cause an error message for the ath10k module:
# dmesg | grep ath
[ 0.865212] ath: module verification failed: signature and/or required key missing - tainted kernal

UPDATE:
I created a directory named
/lib/firmware/ath10k/QCA6174/hw3.0
I then went to https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0
and copied the entire contents into the new directory.
This is where I run into my first issue the github
QCA6174/hw3.0 directory only contained 3 bin files:
board-2.bin
board.bin
firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1
there was no sign of a firmware-3.bin or firmware-2.bin. I
did not touch the other folder in the ath10k folder (my plan
if this worked to to systematically rename them to see if it
mattered; I didn't get that far).
Upon restart, I still get
[ 0.000000] tsc: Fast TSC calibration failed

Given my confusion about the "missing" firmware-3.bin and
firmware-2.bin and the apparent mismatch between the
messages and kernel module, I went back to the start. I
verified the network adapter:
# lspci -nnk | grep Wireless
03:00.0 Network controller [0280]: Qualcom Atheros QCA6714
802.11ac Wireless Ne
twork Adapter [168c:0003e] (rev 32)
ath10k seems the correct module based on Google (I don't
know, I'm new to Linux).
So, then I went back and checked the ath10k messages:
# dmesg | grep ath
[ 0.865212] ath: module verification

I am guessing my issue lies with the "tainted kernal"
message, but don't know how to proceed. Any suggestions?

We need
to find the right firmware(s) for that driver.
From your output above:
> [ 2.880797] ath10k_pci
0000:03:00.0: could not fetch firmware file
'ath10k/QC
>
A6174/hw3.0/firmware-4.bin': -2

looks like we need
ath10k/QCA6174/hw3.0/firmware-4.bin
ath10k/QCA6174/hw3.0/firmware-3.bin
ath10k/QCA6174/hw3.0/firmware-2.bin
yet the kernel module says
otherwise:
$ modinfo
ath10k_pci | grep firmware
firmware:
ath10k/QCA988X/hw2.0/board.bin
firmware:
ath10k/QCA988X/hw2.0/firmware-3.bin
firmware:
ath10k/QCA988X/hw2.0/firmware-2.bin
firmware:
ath10k/QCA988X/hw2.0/firmware.bin
Note /QCA6174/hw3.0/ versus
/QCA988X/hw2.0/ not to mention the different
firmware numbers.
Which is correct? I have no clue so good luck
working it out.
So lets
start at the beginning. There is a Wiki page with some
info
here:
https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/firmware
At a point of reference, your
kmod-ath10k-0.0-4.el7.elrepo.x86_64 driver
is backported from kernel-4.1.26.
The firmware(s) that I
packaged came from here:
https://github.com/kvalo/ath10k-firmware
You need to work out which
firmware(s) you require, and copy them in
place under /lib/firmware/ath10k/ Don't
be afraid to just dump
everything in there
and cover all possibilities - the driver will only
load the firmware it needs. The only caveat is
that the versions must be
correct.
Keep looking in dmesg for
clues as to what the driver is looking for.
Once you have figured it out,
let us know and we can package the
appropriate firmwares for the driver. I
can't do it for you as I don't
have
the hardware to test.
Good
luck!
