      amdgpu: use drm sync objects for shared semaphores (v6) · 660e8558
      由 Dave Airlie 提交于 
      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)

      drm/amd/amdgpu: get maximum and used UVD handles (v4) · 44879b62
      由 Arindam Nath 提交于 
      Change History
--------------

v4: Changes suggested by Emil, Christian
- return -ENODATA for asics with unlimited sessions

v3: changes suggested by Christian
- Add a check for UVD IP block using AMDGPU_HW_IP_UVD
  query type.
- Add a check for asic_type to be less than
  CHIP_POLARIS10 since starting Polaris, we support
  unlimited UVD instances.
- Add kerneldoc style comment for
  amdgpu_uvd_used_handles().

v2: as suggested by Christian
- Add a new query AMDGPU_INFO_NUM_HANDLES
- Create a helper function to return the number
  of currently used UVD handles.
- Modify the logic to count the number of used
  UVD handles since handles can be freed in
  non-linear fashion.

v1:
- User might want to query the maximum number of UVD
  instances supported by firmware. In addition to that,
  if there are multiple applications using UVD handles
  at the same time, he might also want to query the
  currently used number of handles.

  For this we add two variables max_handles and
  used_handles inside drm_amdgpu_info_hw_ip. So now
  an application (or libdrm) can use AMDGPU_INFO IOCTL
  with AMDGPU_INFO_HW_IP_INFO query type to get these
  values.
