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

2024-04-10T14:35:55+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

2024-03-01T12:34:56+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

commit bd1f6a31e7762ebc99b97f3eda5e5ea3708fa792 upstream. When dGPU is put into BOCO it may be in D3cold but still able send PME on display hotplug event. For this to work it must be enabled as wake source from D3. When runpm is enabled use pci_wake_from_d3() to mark wakeup as enabled by default.

drm/amdgpu: expand runpm parameter

2023-08-15T22:08:29+00:00

Allow the user to specify -2 as auto enabled with displays. By default we don't enter runtime suspend when there are displays attached because it does not work well in some desktop environments due to the driver sending hotplug events on resume in case any new displays were attached while the GPU was powered down. Some users still want this functionality though, so this lets you enable it. Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2428 Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher
