drm/amdgpu: skip to program GFXDEC registers for suspend abort

2024-03-01T12:34:56+00:00

[ Upstream commit 93bafa32a6918154aa0caf9f66679a32c2431357 ] In the suspend abort cases, the gfx power rail doesn't turn off so some GFXDEC registers/CSB can't reset to default value and at this moment reinitialize GFXDEC/CSB will result in an unexpected error. So let skip those program sequence for the suspend abort case. Signed-off-by: Prike Liang Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

Revert "drm/amd: Disable S/G for APUs when 64GB or more host memory"

2023-09-11T22:18:17+00:00

This reverts commit 70e64c4d522b732e31c6475a3be2349de337d321. Since, we now have an actual fix for this issue, we can get rid of this workaround as it can cause pin failures if enough VRAM isn't carved out by the BIOS.

drm/amd: Disable S/G for APUs when 64GB or more host memory

2023-08-07T20:32:54+00:00

Users report a white flickering screen on multiple systems that is tied to having 64GB or more memory. When S/G is enabled pages will get pinned to both VRAM carve out and system RAM leading to this. Until it can be fixed properly, disable S/G when 64GB of memory or more is detected. This will force pages to be pinned into VRAM. This should fix white screen flickers but if VRAM pressure is encountered may lead to black screens. It's a trade-off for now.
