2017-03-29drm/amdgpu: simplify reservation handling during buffer creationNicolai Hähnle
By using ttm_bo_init_reserved instead of the manual initialization of the reservation object, the reservation lock will be properly unlocked and destroyed when the TTM BO initialization fails. Actual deadlocks caused by the missing unlock should have been fixed by "drm/ttm: never add BO that failed to validate to the LRU list", superseding the flawed fix in commit 38fc4856ad98 ("drm/amdgpu: fix a potential deadlock in amdgpu_bo_create_restricted()"). This change fixes remaining recursive locking errors that can be seen with lock debugging enabled, and avoids the error of freeing a locked mutex. As an additional minor bonus, buffers created with resv == NULL and the AMDGPU_GEM_CREATE_VRAM_CLEARED flag are now only added to the global LRU list after the fill commands have been issued. v2: use amdgpu_bo_unreserve instead of ttm_bo_unreserve Fixes: 12a852219583 ("drm/amdgpu: improve AMDGPU_GEM_CREATE_VRAM_CLEARED handling (v2)") Signed-off-by: Nicolai Hähnle <nicolai.haehnle@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
