commit 4ad9c1c774c2af152283f510062094e768876f55 upstream.
Otherwise just reinitialize from scratch on resume,
and so make it more likely to succeed.
v2: rebased for 3.10-stable tree

We also need to check the handle.

commit 9cc2e0e9f13315559c85c9f99f141e420967c955 upstream.
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
v4: rebased for 3.10-stable tree
Note: a version of this patch needs to go to stable.

This fixes the kernel side so that the ring should come
up and ring and IB tests should work. The userspace
UVD drivers will also need big endian fixes.

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.

Instead of duplicating the code over and over again, just use a single
function to handle the clock calculations.

That not only saves some power, but also solves problems with
older chips where an idle UVD block on higher clocks can
cause problems.

Message and feedback buffers must be at start of
VRAM, not at start of address space.

Just everything needed to decode videos using UVD.
v6: just all the bugfixes and support for R7xx-SI merged in one patch
v7: UVD_CGC_GATE is a write only register, lockup detection fix
v8: split out VRAM fallback changes, remove support for RV770,
add support for HEMLOCK, add buffer sizes checks
