This patch intorduces new UAPI/IOCTL for usermode graphics
queue. The userspace app will fill this structure and request
the graphics driver to add a graphics work queue for it. The
output of this UAPI is a queue id.
This UAPI maps the queue into GPU, so the graphics app can start
submitting work to the queue as soon as the call returns.
V2: Addressed review comments from Alex and Christian
- Make the doorbell offset's comment clearer
- Change the output parameter name to queue_id
V3: Integration with doorbell manager
V4:
- Updated the UAPI doc (Pierre-Eric)
- Created a Union for engine specific MQDs (Alex)
- Added Christian's R-B
V5:
- Add variables for GDS and CSA in MQD structure (Alex)
- Make MQD data a ptr-size pair instead of union (Alex)
V9:
- renamed struct drm_amdgpu_userq_mqd_gfx_v11 to struct
drm_amdgpu_userq_mqd as its being used for SDMA and
compute queues as well
V10:
- keeping the drm_amdgpu_userq_mqd IP independent, moving the
_gfx_v11 objects in a separate structure in other patch.
