DP connection swap to break eDP behavior on AMD 7735U

[Anson Tsao]

[Impact]
Some OEM platforms swap DP connections on the Rembrandt-R, which causes improper eDP behavior. The following issues will occur in these designs:

- Fn key failed to control brightness
- eDP remains black screen during S0i3 cycle

AMD has fixed these issues, but it requires both a kernel patch and an updated DMCUB microcode.

[Test Plan]
Validate brightness control works.
Validate that PSR works.
Validate that eDP works after suspend/resume.
Validate that external display works.

Run above test plan on Rembrandt or Rembrandt-R system with swapped DP as well as one without swapped DP.

[Where problems can occur]
The code and DMCUB microcode are localized to AMD Rembrandt/Rembrandt-R systems. Issues would occur specifically on these designs, which is why they should be tested.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-6.5/6.5.0-1014.15 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-jammy-linux-oem-6.5' to 'verification-done-jammy-linux-oem-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

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!

[Anson Tsao (ansontsao)]

Verified oem-6.5-1014 on my end with new DMCUB FW(Manually added), I don't observe this issue happening. We are still waiting for the new DMCUB FW to be added into linux-firmware for jammy, not sure if we need one more similar public bug to track FW landing.

I will tag "done" from the patch backport perspective.

[You-Sheng Yang (vicamo)]

While the proposed firmware fix is already in upstream repository, it shall be included when linux-firmware/noble is rebased to the latest HEAD.

That's actually the wrong firmware commit, upstream main has this now:

    DMCUB updates for DCN312.
    From internal git commit cc6d1d24518bfde45c01acfc760b3be5e1112d24.

    Firmware release 0.0.199.0
    Tested with DC 3.2.266

    Release notes:

    Address DP connection swap(DP0-->HDMI & DP1-->eDP) issue caused by:
    * Fn key failed to control brightness

    Signed-off-by: Rodrigo Siqueira <email address hidden>

which fixes that it is for DCN312/YC only.

Internal team at AMD has tested an OEM RMB that doesn't need the DP swap change to check for any potential regression. They tested using OEM 6.5-1014 kernel. This testing well.

Anson will confirm results on the system needing DP swap after he's back from holiday.

Verified on the OEM platform, and looks positive on my end.

Verified on top of v6.8-rc5 with 20230919.git3672ccab-0ubuntu2.9, got positive on my end. But looks like one more action to backport the patch into mantic as well, got negative on top of mantic-linux-6.5.0-25.25 with the same linux-firmware package.

even though this wasn't able to get verified with the mantic kernel, I've gone ahead and released it as the update should not break anything

[Timo Aaltonen (tjaalton)]

marking the kernel task as fixed since noble has 6.8 now.
