amdgpu: use drm sync objects for shared semaphores (v6)

2017-06-16T20:58:32+00:00

This creates a new command submission chunk for amdgpu to add in and out sync objects around the submission. Sync objects are managed via the drm syncobj ioctls. The command submission interface is enhanced with two new chunks, one for syncobj pre submission dependencies, and one for post submission sync obj signalling, and just takes a list of handles for each. This is based on work originally done by David Zhou at AMD, with input from Christian Konig on what things should look like. In theory VkFences could be backed with sync objects and just get passed into the cs as syncobj handles as well. NOTE: this interface addition needs a version bump to expose it to userspace. TODO: update to dep_sync when rebasing onto amdgpu master. (with this - r-b from Christian) v1.1: keep file reference on import. v2: move to using syncobjs v2.1: change some APIs to just use p pointer. v3: make more robust against CS failures, we now add the wait sems but only remove them once the CS job has been submitted. v4: rewrite names of API and base on new syncobj code. v5: move post deps earlier, rename some apis v6: lookup post deps earlier, and just replace fences in post deps stage (Christian) Reviewed-by: Christian König Signed-off-by: Dave Airlie Signed-off-by: Alex Deucher

drm/amdgpu: untie user ring ids from kernel ring ids v6

2017-05-31T20:49:01+00:00

Add amdgpu_queue_mgr, a mechanism that allows disjointing usermode's ring ids from the kernel's ring ids. The queue manager maintains a per-file descriptor map of user ring ids to amdgpu_ring pointers. Once a map is created it is permanent (this is required to maintain FIFO execution guarantees for a context's ring). Different queue map policies can be configured for each HW IP. Currently all HW IPs use the identity mapper, i.e. kernel ring id is equal to the user ring id. The purpose of this mechanism is to distribute the load across multiple queues more effectively for HW IPs that support multiple rings. Userspace clients are unable to check whether a specific resource is in use by a different client. Therefore, it is up to the kernel driver to make the optimal choice. v2: remove amdgpu_queue_mapper_funcs v3: made amdgpu_queue_mgr per context instead of per-fd v4: add context_put on error paths v5: rebase and include new IPs UVD_ENC & VCN_* v6: drop unused amdgpu_ring_is_valid_index (Alex) Reviewed-by: Christian König Signed-off-by: Andres Rodriguez Signed-off-by: Alex Deucher
