V1: Worked on review comments from RFC patch series: - Alex: Keep a list of queues, instead of single queue per process. - Christian: Use the queue manager instead of global ptrs, Don't keep the queue structure in amdgpu_ctx V2: Worked on review comments: - Christian: - Formatting of text - There is no need for queuing of userqueues, with idr in place - Alex: - Remove use_doorbell, its unnecessary - Reuse amdgpu_mqd_props for saving mqd fields - Code formatting and re-arrangement V3: - Integration with doorbell manager V4: - Accommodate MQD union related changes in UAPI (Alex) - Do not set the queue size twice (Bas) V5: - Remove wrapper functions for queue indexing (Christian) - Do not save the queue id/idr in queue itself (Christian) - Move the idr allocation in the IP independent generic space (Christian) V6: - Check the validity of input IP type (Christian) V7: - Move uq_func from uq_mgr to adev (Alex) - Add missing free(queue) for error cases (Yifan) V9: - Rebase V10: Addressed review comments from Christian, and added R-B: - Do not initialize the local variable - Convert DRM_ERROR to DEBUG. V11: - check the input flags to be zero (Alex) Cc: Alex Deucher Cc: Christian Koenig Reviewed-by: Christian Koenig Reviewed-by: Alex Deucher Signed-off-by: Shashank Sharma Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index 1d41e45a317e..dd2ec890d186 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -2948,6 +2948,7 @@ const struct drm_ioctl_desc amdgpu_ioctls_kms[] = { DRM_IOCTL_DEF_DRV(AMDGPU_GEM_VA, amdgpu_gem_va_ioctl, DRM_AUTH|DRM_RENDER_ALLOW), DRM_IOCTL_DEF_DRV(AMDGPU_GEM_OP, amdgpu_gem_op_ioctl, DRM_AUTH|DRM_RENDER_ALLOW), DRM_IOCTL_DEF_DRV(AMDGPU_GEM_USERPTR, amdgpu_gem_userptr_ioctl, DRM_AUTH|DRM_RENDER_ALLOW), + DRM_IOCTL_DEF_DRV(AMDGPU_USERQ, amdgpu_userq_ioctl, DRM_AUTH|DRM_RENDER_ALLOW), }; static const struct drm_driver amdgpu_kms_driver = { -- cgit v1.2.3
