Alex Deucher ce3537d571 drm/radeon/dpm: use multiple UVD power states (v3)
Use the UVD handle information to determine which
which power states to select when using UVD.  For
example, decoding a single SD stream requires much
lower clocks than multiple HD streams.

v2: switch to a cleaner dpm/uvd interface
v3: change the uvd power state while streams
are active if need be

Alex Deucher 85a129ca8d drm/radeon: add UVD->DPM helper function (v5)
Add a helper function for counting the number of open stream handles.

v2: fix copy-pasta in comments and whitespace error
v3: make function static since it's only used in radeon_uvd.c
at the moment
v4: make non-static again for future changes
v5: make static again for new rework of dpm uvd changes

Otherwise just reinitialize from scratch on resume,
and so make it more likely to succeed.

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.

Avoid creating temporary platform device that will lead to issue
when several radeon gpu are in same computer. Instead directly use

Maarten Lankhorst ecff665f5e drm/ttm: make ttm reservation calls behave like reservation calls
This commit converts the source of the val_seq counter to
the ww_mutex api. The reservation objects are converted later,
because there is still a lockdep splat in nouveau that has to
resolved first.

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.

V2: fix locking.

V3: switch from timer to delayed work

V4: check fence driver for UVD jobs, reduce timeout to
    1 second and rearm timeout on activity

v5: rebase on new dpm tree

v6: rebase on interim uvd on demand changes

v7: fix UVD when DPM is disabled

v8: unify non-DPM and DPM UVD handling

v9: remove leftover idle work struct

Jerome Glisse 089920f21d drm/radeon: fix write back suspend regression with uvd v2
UVD ring can't use scratch thus it does need writeback buffer to keep
a valid address or radeon_ring_backup will trigger a kernel fault.

It's ok to not unpin the write back buffer on suspend as it leave in
gtt and thus does not need eviction.

v2: Fix the uvd case.
