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>

2017-02-09drm/amdgpu: fix a potential deadlock in amdgpu_bo_create_restricted()Samuel Pitoiset
When ttm_bo_init() fails, the reservation mutex should be unlocked. In debug build, the kernel reported "possible recursive locking detected" in this codepath. For debugging purposes, I also added a "WARN_ON(ww_mutex_is_locked())" when ttm_bo_init() fails and the mutex was locked as expected. This should fix (random) GPU hangs. The easy way to reproduce the issue is to change the "Super Sampling" option from 1.0 to 2.0 in Hitman. It will create a huge buffer, evict a bunch of buffers (around ~5k) and deadlock. This regression has been introduced pretty recently. v2: only release the mutex if resv is NULL Fixes: 12a852219583 ("drm/amdgpu: improve AMDGPU_GEM_CREATE_VRAM_CLEARED handling (v2)") Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2017-02-09drm/amdgpu: shut up #warning for compile testingArnd Bergmann
My randconfig tests on linux-next showed a newly introduced warning: drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function 'amdgpu_bo_create_restricted': drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:377:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp] Generally speaking, warnings about bad kernel configuration are not particularly helpful. We could enforce the selection of X86_PAT through Kconfig, so the driver cannot even be used unless it is enabled, or we could just rely on the runtime warning that is also there. In this version, I'm making the warning conditional on CONFIG_COMPILE_TEST, which shuts it up for me, but not people that may actually want to run the kernel as a compromize.
