drm/amd: Evict resources during PM ops prepare() callback

2024-04-10T14:28:28+00:00

[ Upstream commit 5095d5418193eb2748c7d8553c7150b8f1c44696 ] Linux PM core has a prepare() callback run before suspend. If the system is under high memory pressure, the resources may need to be evicted into swap instead. If the storage backing for swap is offlined during the suspend() step then such a call may fail. So move this step into prepare() to move evict majority of resources and update all non-pmops callers to call the same callback.

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

2024-03-01T12:26:30+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"

2023-09-23T09:11:10+00:00

commit 169ed4ece8373f02f10642eae5240e3d1ef5c038 upstream. 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/pm: avoid unintentional shutdown due to temperature momentary fluctuation

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

2023-08-16T16:27:22+00:00

commit 08fffa74d9772d9538338be3f304006c94dde6f0 upstream. 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.

drm/amdgpu: add S/G display parameter

2023-08-16T16:27:22+00:00

commit bf0207e1727031798f300afa17f9bbeceac6da87 upstream. 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 Acked-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
