Christian König 9cc2e0e9f1 drm/radeon: never unpin UVD bo v3
Changing the UVD BOs offset on suspend/resume doesn't work because the VCPU
internally keeps pointers to it. Just keep it always pinned and save the
content manually.

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=66425

v2: fix compiler warning
v3: fix CIK support

Note: a version of this patch needs to go to stable.

This allows you to force specific power levels within a power

Alex Deucher edcaa5b125 drm/radeon: add support for 3d perf states on older asics
Certain older rv770 asics have both a performance and
a 3D performance state rather than just multiple performance
levels in the state power state.  The current code would
select the performance state rather than the 3D performance
state when the "performance" profile was selected.  This change
switches to the "balanced" profile by default which ends up being
the internal performance profile.  When the user selects the
"performance" profile, it selects the internal 3D performance
state so the user can select the higher performance modes.

For most asics this changes nothing.  For certain rv770 asics
with static performance and 3D performance states, this allows
you to select between then using by selecting the "balanced"
and "performance" dpm profiles.

Alex Deucher 8a227555a8 drm/radeon/kms: enable UVD as needed (v9)
When using UVD, the driver must switch to a special UVD power
state.  In the CS ioctl, switch to the power state and schedule
work to change the power state back, when the work comes up,
check if uvd is still busy and if not, switch back to the user
state, otherwise, reschedule the work.

Note:  We really need some better way to decide when to
switch out of the uvd power state.  Switching power states
while playback is active make uvd angry.

Alex Deucher 963e81f9e0 drm/radeon/cik: Add support for compute queues (v4)
On CIK, the compute rings work slightly differently than
on previous asics, however the basic concepts are the same.

The main differences:
- New MEC engines for compute queues
- Multiple queues per MEC:
  - CI/KB: 1 MEC, 4 pipes per MEC, 8 queues per pipe = 32 queues
  -    KV: 2 MEC, 4 pipes per MEC, 8 queues per pipe = 64 queues
- Queues can be allocated and scheduled by another queue

  for the wptr which allows for userspace access to queues
