Bug Description
[SRU Justification]
[Impact]
No general user impact. Only for synchronizing configs between oem-5.10
and hirsute/unstable.
[Fix]
In one of the patches landed for bug 1879633 we enabled debugfs/tracing
for ath11k driver:
https:/
This patchset was also proposed for unstable at the time. Resubmit this
part for both hirsute and unstable v5.12 again.
[Test Case]
Check if now debugfs is available for ath11k:
$ ls /sys/kernel/
qca6390 hw2.0
[Where problems could occur]
This should be unrelated to core functions, but might introduce
performance lose, undefined/untested behaviors when enabled.
[Other Info]
The rest parts to enable ath11k support have been included in v5.11, so
they're skipped here.
