Arunpravin Paneer Selvam 95a16160ca drm/amdgpu: Reset the clear flag in buddy during resume ... - 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.
