2015-08-17drm/amd: add basic scheduling frameworkJammy Zhou1-0/+531
run queue: A set of entities scheduling commands for the same ring. It implements the scheduling policy that selects the next entity to emit commands from. entity: A scheduler entity is a wrapper around a job queue or a group of other entities. This can be used to build hierarchies of entities. For example all job queue entities belonging to the same process may be placed in a higher level entity and scheduled against other process entities. Entities take turns emitting jobs from their job queue to the corresponding hardware ring, in accordance with the scheduler policy.
