Subject: drm/radeon: Disable dma rings for bo moves on r6xx
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit aeea40cbf9388fc829e66fa049f64d97fd72e118 upstream.
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.
