Bug Description

[SRU Justification]

[Impact]

Bug 1928857 pulls stable patches from v5.11.20, which contains commit
dc764382762e {"bus: mhi: core: Process execution environment changes
serially") that cause a regression on ath11k cards and fails device
init:

  mhi mhi0: MHI did not enter SBL

[Fix]

Upsteram commit 4884362f6977 ("bus: mhi: core: Download AMSS image
from appropriate function"), also landed to v5.12.6 but not v5.11
stable tree, has fixed this.

[Test Case]

Tested on Dell XPS 13 9310. No longer has this regression and both
WiFi/Bluetooth works fine as before.

[Where problems could occur]

The actual firmware downloading process is moved into a state machine
callback that has identical semantics with before. Additions or removals
to this in the future may change the timing of fw being dowloaded.

[Other Info]

While the commit causing this regress is backported to 5.11 onward and
fixed in v5.12 and 5.13, leaving Hirsute is the only victim.

Can you please prevent this already fixed bug from being introduced any further into Ubuntu.
Thanks.

This is reproducible with 5.11.0-19-generic from hirsute-proposed, but not reproducible with 5.13 for impish. Also oem kernels (5.10-oem-1029, 5.13-oem) are not affected.

See my reply here:

I describe that I am tested 5.11.0-20 right now.

So WIFI ath11k works (and Soundwire, that's the bugreport that I am replying on). A new graphics related issues occurs with the generic version of the kernel, lowlatency works fine.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Ok, although I am normally using Hirsute, today I installed Focal, so I could do the requested testing here for Focal as well.
I tested:
 - 5.11.0-20-generic
 - 5.11.0-20-lowlatency
 - 5.11.0-22-generic
 - 5.11.0-22-lowlatency
 - 5.11.0-23-generic
 - 5.11.0-23-lowlatency

Because these where the kernels that I got available today with Proposed enabled.

All of these kernels give me a working Soundwire and a working ath11k!
