drm/amdgpu: Reset the clear flag in buddy during resume

2025-07-16T10:50:32Z

- Added a handler in DRM buddy manager to reset the cleared flag for the blocks in the freelist. - This is necessary because, upon resuming, the VRAM becomes cluttered with BIOS data, yet the VRAM backend manager believes that everything has been cleared. v2: - Add lock before accessing drm_buddy_clear_reset_blocks()(Matthew Auld) - Force merge the two dirty blocks.(Matthew Auld) - Add a new unit test case for this issue.(Matthew Auld) - Having this function being able to flip the state either way would be good. (Matthew Brost) v3(Matthew Auld): - Do merge step first to avoid the use of extra reset flag.

drm/amdgpu: switch job hw_fence to amdgpu_fence

2025-06-18T17:15:26Z

Use the amdgpu fence container so we can store additional data in the fence. This also fixes the start_time handling for MCBP since we were casting the fence to an amdgpu_fence and it wasn't.

drm/amdgpu: fix pm notifier handling

2025-05-07T21:43:18Z

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

drm/amdgpu: Implement unrecoverable error message handling for VFs

2025-05-07T21:43:13Z

This notification may arrive in VF mailbox while polling for response from another event. This patches covers the following scenarios: - If VF is already in RMA state, then do not attempt to contact the host. Host will ignore the VF after sending the notification. - If the notification is detected during polling, then set the RMA status, and return error to caller. - If the notification arrives by interrupt, then set the RMA status and queue a reset. This reset will fail and VF will stop runtime services. Reviewed-by: Shravan Kumar Gande Signed-off-by: Victor Skvortsov Signed-off-by: Ellen Pan Signed-off-by: Alex Deucher

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

2025-05-07T21:42:30Z

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.
