Bug description:
[SRU Justification]
[Impact]
Multiple issues in DP alt mode, PSR-SU(Panel Self Refresh–Selective
Update), and HDMI signal integrity.
[Fix]
Upstream commit b0f995cd61cd ("amdgpu: update DMCUB firmware for DCN
3.1.6") that updates binary firmware.
[Test Case]
Can only be verified with dedicated equipment from vendor.
[Where problems could occur]
Binary firmware, everything can go wrong.
[Other Info]
Already in korg upstream, included in Lunar, too. Only Jammy and
Kinetic will be nominated for fix.
========== original bug report ==========
Some fixes for DP alt mode and PSR-SU(Panel Self Refresh–Selective
Update), and also improve HDMI signal integrity. This FW would be
tuning PHY of HDMI to enhance signal integrity in eye diagram to reach
HDMI spec(2.0/1.4b), and also avoid any risk on monitor with multiple
resolutions over HDMI output.
