drm/amdgpu: fix pm notifier handling

2025-05-22T12:12:26Z

commit 4aaffc85751da5722e858e4333e8cf0aa4b6c78f upstream. Set the s3/s0ix and s4 flags in the pm notifier so that we can skip the resource evictions properly in pm prepare based on whether we are suspending or hibernating. Drop the eviction as processes are not frozen at this time, we we can end up getting stuck trying to evict VRAM while applications continue to submit work which causes the buffers to get pulled back into VRAM. v2: Move suspend flags out of pm notifier (Mario) Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4178 Fixes: 2965e6355dcd ("drm/amd: Add Suspend/Hibernate notification callback support") Cc: Mario Limonciello Reviewed-by: Mario Limonciello Signed-off-by: Alex Deucher (cherry picked from commit 06f2dcc241e7e5c681f81fbc46cacdf4bfd7d6d7) Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

drm/amd/display: Avoid flooding unnecessary info messages

2025-05-22T12:12:20Z

commit d33724ffb743d3d2698bd969e29253ae0cff9739 upstream. It's expected that we'll encounter temporary exceptions during aux transactions. Adjust logging from drm_info to drm_dbg_dp to prevent flooding with unnecessary log messages.

drm/amd/display: Correct the reply value when AUX write incomplete

2025-05-22T12:12:19Z

commit d433981385c62c72080e26f1c00a961d18b233be upstream. [Why] Now forcing aux->transfer to return 0 when incomplete AUX write is inappropriate. It should return bytes have been transferred. [How] aux->transfer is asked not to change original msg except reply field of drm_dp_aux_msg structure. Copy the msg->buffer when it's write request, and overwrite the first byte when sink reply 1 byte indicating partially written byte number. Then we can return the correct value without changing the original msg.

Revert "drm/amd: Stop evicting resources on APUs in suspend"

2025-05-22T12:12:14Z

[ Upstream commit d0ce1aaa8531a4a4707711cab5721374751c51b0 ] This reverts commit 3a9626c816db901def438dc2513622e281186d39. This breaks S4 because we end up setting the s3/s0ix flags even when we are entering s4 since prepare is used by both flows. The causes both the S3/s0ix and s4 flags to be set which breaks several checks in the driver which assume they are mutually exclusive.

drm/amd: Add Suspend/Hibernate notification callback support

2025-05-22T12:12:14Z

[ Upstream commit 2965e6355dcdf157b5fafa25a2715f00064da8bf ] As part of the suspend sequence VRAM needs to be evicted on dGPUs. In order to make suspend/resume more reliable we moved this into the pmops prepare() callback so that the suspend sequence would fail but the system could remain operational under high memory usage suspend. Another class of issues exist though where due to memory fragementation there isn't a large enough contiguous space and swap isn't accessible. Add support for a suspend/hibernate notification callback that could evict VRAM before tasks are frozen. This should allow paging out to swap if necessary.

drm/amd: Stop evicting resources on APUs in suspend

[ Upstream commit 226db36032c61d8717dfdd052adac351b22d3e83 ] 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 Stable-dep-of: d0ce1aaa8531 ("Revert "drm/amd: Stop evicting resources on APUs in suspend"") Signed-off-by: Sasha Levin
