From 53b3f8f40e6cff36ae12b11e6d6b308af3c7e53f Mon Sep 17 00:00:00 2001 From: Dennis Li Date: Wed, 19 Aug 2020 17:23:03 +0800 Subject: drm/amdgpu: refine codes to avoid reentering GPU recovery if other threads have holden the reset lock, recovery will fail to try_lock. Therefore we introduce atomic hive->in_reset and adev->in_gpu_reset, to avoid reentering GPU recovery. v2: drop "? true : false" in the definition of amdgpu_in_reset Reviewed-by: Hawking Zhang Signed-off-by: Dennis Li Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c index 3d2712a4cf4d..97449ab24c20 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c @@ -2098,7 +2098,7 @@ void amdgpu_ttm_set_buffer_funcs_status(struct amdgpu_device *adev, bool enable) uint64_t size; int r; - if (!adev->mman.initialized || adev->in_gpu_reset || + if (!adev->mman.initialized || amdgpu_in_reset(adev) || adev->mman.buffer_funcs_enabled == enable) return; -- cgit v1.2.3
