Bug description:
[SRU Justification]
[Impact]
USB4 DP alt mode not available on AMD yellow carp.
[Fix]
Several fixing commits from upstream, inclusive of one titled
"drm/amd/display: Fixup previous PSR policy commit" sauced commit to
fix backport problems for commit 9470620e99e9 ("drm/amd/display: Enable
PSR by default on newer DCN").
This also depends on the firmware updates.
[Test Case]
Plug an external monitor with USB Type-C input function to AMD RMB CRB
(which has yellow carp) usbc0 and usbc1.
[Where problems could occur]
The patches revealed multiple dmub firmware versions were skipped. This
might introduce incompatibilities between driver code and the firmware.
========== linux-firmware SRU ==========
[Impact]
Need new firmware to enable USB4 DP alt mode for AMD yellow carp.
[Fix]
Already-in-upstream commit 581f8a3aae02 ("amdgpu: update yellow carp
dmcub firmware") to be backported.
[Test Case]
Need also kernel driver fixes to verify.
[Where problems could occur]
This introduces new features required both kernel driver and firmware
updates, the firmware part might cause instability or so.
