So, for sriov use case, the timeout setting on compute rings is kept. -v2: clean the code Signed-off-by: Evan Quan Reviewed-by: Christian König Reviewed-by: Monk Liu Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c index 455a81e4c246..97449e06a242 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c @@ -410,6 +410,7 @@ int amdgpu_fence_driver_start_ring(struct amdgpu_ring *ring, int amdgpu_fence_driver_init_ring(struct amdgpu_ring *ring, unsigned num_hw_submission) { + long timeout; int r; /* Check that num_hw_submission is a power of two */ @@ -433,11 +434,16 @@ int amdgpu_fence_driver_init_ring(struct amdgpu_ring *ring, /* No need to setup the GPU scheduler for KIQ ring */ if (ring->funcs->type != AMDGPU_RING_TYPE_KIQ) { + /* for non-sriov case, no timeout enforce on compute ring */ + if ((ring->funcs->type == AMDGPU_RING_TYPE_COMPUTE) + && !amdgpu_sriov_vf(ring->adev)) + timeout = MAX_SCHEDULE_TIMEOUT; + else + timeout = msecs_to_jiffies(amdgpu_lockup_timeout); + r = drm_sched_init(&ring->sched, &amdgpu_sched_ops, num_hw_submission, amdgpu_job_hang_limit, - (ring->funcs->type == AMDGPU_RING_TYPE_COMPUTE) ? - MAX_SCHEDULE_TIMEOUT : msecs_to_jiffies(amdgpu_lockup_timeout), - ring->name); + timeout, ring->name); if (r) { DRM_ERROR("Failed to create scheduler on ring %s.\n", ring->name);
