[ Upstream commit 067f44c8b4590c3f24d21a037578a478590f2175 ]

In amdgpu_fence_driver_hw_fini, no need to call drm_sched_fini to stop
scheduler in s3 test, otherwise, fence related failure will arrive
after resume. To fix this and for a better clean up, move drm_sched_fini
from fence_hw_fini to fence_sw_fini, as it's part of driver shutdown, and
should never be called in hw_fini.

v2: rename amdgpu_fence_driver_init to amdgpu_fence_driver_sw_init,
to keep sw_init and sw_fini paired.

Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1668
Fixes: 8d35a2596164c1 ("drm/amdgpu: adjust fence driver enable sequence")

[ Upstream commit 8d35a2596164c1c9d34d4656fd42b445cd1e247f ]

Fence driver was enabled per ring when sw init on per IP block before.
Change to enable all the fence driver at the same time after
amdgpu_device_ip_init finished.
Rename some function related to fence to make it reasonable for read.

Some of the stuff in amdgpu_device_fini such as HW interrupts
disable and pending fences finilization must be done right away on
pci_remove while most of the stuff which relates to finilizing and
releasing driver data structures can be kept until
drm_driver.release hook is called, i.e. when the last device
reference is dropped.

v4: Change functions prefix early-&gt;hw and late-&gt;sw

<title>drm/amdgpu: add wave limit functionality for gfx8,9</title>

Wave limiting can be use to load balance high priority
compute jobs along with gfx jobs. When enabled, this will reserve
~75% of waves for compute jobs.

We do not need this from gfx10 onwards because &gt;=gfx10 has
asynchronous compute tunneling to replace wave limit requirement.

This patch consist of below related changes:

1 Rename ring-&gt;priority to ring-&gt;hw_prio.
2 Assign correct hardware ring priority.
3 Remove ring-&gt;priority_mutex as ring priority remains unchanged
  after initialization.
4 Remove unused ring-&gt;num_jobs.

v3: remove ring-&gt;num_jobs.
v2: remove ring-&gt;priority_mutex.

Remove DRM_SCHED_PRIORITY_LOW, as it was used
in only one place.

Rename and separate by a line
DRM_SCHED_PRIORITY_MAX to DRM_SCHED_PRIORITY_COUNT
as it represents a (total) count of said
priorities and it is used as such in loops
throughout the code. (0-based indexing is the
the count number.)

Remove redundant word HIGH in priority names,
and rename *KERNEL* to *HIGH*, as it really
means that, high.

v2: Add back KERNEL and remove SW and HW,
    in lieu of a single HIGH between NORMAL and KERNEL.
