They still seem to cause instability on some r6xx parts.
As a follow up, we can switch to using CP DMA for bo
moves on r6xx as a lighter weight alternative to using
the 3D engine.
A version of this patch should also go to stable kernels.

"drm/nve0-/gr: some new gpc registers can have multiple copies"
5ee86c4190f9e caused a regression for nvc0, because the bit indicating last
transfer has occured was no longer set, resulting in random system lockups.

This allows you to force specific power levels within a power

interface is limited to the following 3 selections:
auto: all levels enabled
low: forced to the lowest power level

r1xx asics have a slightly different surface register
setup compared to newer asics. There is no specific
enable bit for macro tiling, rather, to disable macro
tiling, you need to set the surface pitch to 0.
With this fixed, the special rn50 handling can go.

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.
