2022-01-27drm/amdgpu: Wipe all VRAM on free when RAS is enabledFelix Kuehling1-0/+3
On GPUs with RAS, poison can propagate between processes if VRAM is not cleared when it is freed or allocated. The reason is, that not all write accesses clear RAS poison. 32-byte writes by the SDMA engine do clear RAS poison. Clearing memory in the background when it is freed should avoid major performance impact. KFD has been doing this already for a long time.

amdgpu_dm_connector_add_common_modes() In amdgpu_dm_connector_add_common_modes(), amdgpu_dm_create_common_mode() is assigned to mode and is passed to drm_mode_probed_add() directly after that. drm_mode_probed_add() passes &mode->head to list_add_tail(), and there is a dereference of it in list_add_tail() without recoveries, which could lead to NULL pointer dereference on failure of amdgpu_dm_create_common_mode().
