2023-03-23drm/amdgpu/nv: Apply ASPM quirk on Intel ADL + AMD NaviKai-Heng Feng1-0/+1
S2idle resume freeze can be observed on Intel ADL + AMD WX5500. This is caused by commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default"). The root cause is still not clear for now. So extend and apply the ASPM quirk from commit e02fe3bc7aba ("drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systems"), to workaround the issue on Navi cards too.

2023-02-09drm/amdgpu: add S/G display parameterAlex Deucher1-0/+1
Some users have reported flickerng with S/G display. We've tried extensively to reproduce and debug the issue on a wide variety of platform configurations (DRAM bandwidth, etc.) and a variety of monitors, but so far have not been able to. We disabled S/G display on a number of platforms to address this but that leads to failure to pin framebuffers errors and blank displays when there is memory pressure or no displays at all on systems with limited carveout (e.g., Chromebooks). Add a option to disable this as a debugging option as a way for users to disable this, depending on their use case, and for us to help debug this further. v2: fix typo Reviewed-by: Harry Wentland <harry.wentland@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-01-05drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interruptxurui1-1/+1
HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.
