[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://lists.ubuntu.com/archives/kernel-team/2020-December/115417.html
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/debug/ath11k
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.
========== original bug description ==========
In bug 1879633, CONFIG_ATH11K_DEBUGFS/CONFIG_ATH11K_TRACING were enabled by default for oem-5.10. Since this is also the case for ath10k and ath9k in -generic kernels, we'd like to sync the behaviors in ath9/10/11k.
