This patch adds:
- A new IOCTL function to create and destroy
- A new structure to keep all the user queue data in one place.
- A function to generate unique index for the queue.
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)
