<id>urn:sha1:929ae7c2e3adbbb2c2bddcd16854a6b11b56e95a</id>
<content type='text'>
This series adds a deadline hint to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
frequency management decisions.

This is partially inspired by a trick i915 does, but implemented
via dma-fence for a couple of reasons:

1) To continue to be able to use the atomic helpers
2) To support cases where display and gpu are different drivers

See https://patchwork.freedesktop.org/series/93035/

This does not yet add any UAPI, although this will be needed in
a number of cases:

1) Workloads "ping-ponging" between CPU and GPU, where we don't
   want the GPU freq governor to interpret time stalled waiting
   for GPU as "idle" time
2) Cases where the compositor is waiting for fences to be signaled
   before issuing the atomic ioctl, for example to maintain 60fps
   cursor updates even when the GPU is not able to maintain that
   framerate.

<id>urn:sha1:f3823da7e4ba7d4781375c2bb786a8a78efc6591</id>
<content type='text'>
As the finished fence is the one that is exposed to userspace, and
therefore the one that other operations, like atomic update, would
block on, we need to propagate the deadline from from the finished
fence to the actual hw fence.

v2: Split into drm_sched_fence_set_parent() (ckoenig)
v3: Ensure a thread calling drm_sched_fence_set_deadline_finished() sees
    fence-&gt;parent set before drm_sched_fence_set_parent() does this
    test_bit(DMA_FENCE_FLAG_HAS_DEADLINE_BIT).

<content type='text'>
In order to add a syncobj's fence as a dependency to a job, it is
necessary to call drm_syncobj_find_fence() to find the fence and then
add the dependency with drm_sched_job_add_dependency(). So, wrap these
steps in one single function, drm_sched_job_add_syncobj_dependency().

<content type='text'>
This time we've added support for reporting of GPU load via the common
fdinfo format, as already supported by multiple other drivers. Improved
diagnostic messages for MMU faults. And finally added experimental
support for driving the VeriSilicon NPU cores, which are very close
relatives to the GPU designs, so close in fact that they can run the
same compute instruction set, but with a big NN-fabric/matrix/tensor
execution array glued to the side.

Track the accumulated time that jobs from this entity were active
on the GPU. This allows drivers using the scheduler to trivially
implement the DRM fdinfo when the hardware doesn't provide more
specific information than signalling job completion anyways.

UAPI:
- Add new GEM_CREATE flags to help to transition more KFD functionality to the DRM UAPI.
  These are used internally in the driver to align location based memory coherency
  requirements from memory allocated in the KFD with how we manage GPUVM PTEs.  They
  are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now.
  They are just used internally in the kernel driver for now for existing KFD memory
  allocations. So a change to the UAPI header, but no functional change in the UAPI.
