Need to initialize the mask to 0 on init, otherwise it
keeps increasing.

drm/radeon: Sync ME and PFP after CP semaphore waits v4

2014-08-19T15:44:47+00:00

Fixes lockups due to CP read GPUVM faults when running piglit on Cape
Verde.

v2 (chk): apply the fix to R600+ as well, on CIK only the GFX CP has
	  a PFP, add more comments to R600 code, enable flushing again
v3: (agd5f): only apply to 7xx+.  r6xx does not have the packet.
v4: (agd5f): split flush change into a separate patch, fix formatting

drm/radeon: fix display handling in radeon_gpu_reset

2014-08-19T15:29:22+00:00

If the display hw was reset or a hard reset was used,
we need to re-init some of the common display hardware as well.

drm/radeon: fix pm handling in radeon_gpu_reset

2014-08-19T15:29:21+00:00

pm_suspend is handled in the radeon_suspend callbacks.
pm_resume has special handling depending on whether
dpm or legacy pm is enabled.  Change radeon_gpu_reset
to mirror the behavior in the suspend and resume
pathes.

drm/radeon: Only flush HDP cache for indirect buffers from userspace

2014-08-18T21:09:44+00:00

It isn't necessary for command streams generated by the kernel (at least
not while we aren't storing ring or indirect buffers in VRAM).
