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.
