drm/amd: Stop evicting resources on APUs in suspend

2024-02-15T19:18:43Z

commit 5095d5418193 ("drm/amd: Evict resources during PM ops prepare() callback") intentionally moved the eviction of resources to earlier in the suspend process, but this introduced a subtle change that it occurs before adev->in_s0ix or adev->in_s3 are set. This meant that APUs actually started to evict resources at suspend time as well. Explicitly set s0ix or s3 in the prepare() stage, and unset them if the prepare() stage failed. v2: squash in warning fix from Stephen Rothwell Reported-by: Jürg Billeter Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3132#note_2271038 Fixes: 5095d5418193 ("drm/amd: Evict resources during PM ops prepare() callback") Acked-by: Alex Deucher Signed-off-by: Mario Limonciello Signed-off-by: Alex Deucher

drm/amdgpu: make damage clips support configurable

2024-02-15T19:18:42Z

We have observed that there are quite a number of PSR-SU panels on the market that are unable to keep up with what user space throws at them, resulting in hangs and random black screens. So, make damage clips support configurable and disable it by default for PSR-SU displays.

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

2024-02-07T23:19:04Z

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

drm/amdgpu: Enable tunneling on high-priority compute queues

2023-12-13T20:23:59Z

This improves latency if the GPU is already busy with other work. This is useful for VR compositors that submit highly latency-sensitive compositing work on high-priority compute queues while the GPU is busy rendering the next frame.
