From: Alex Deucher Date: Thu, 11 Jul 2013 18:20:11 +0000 (-0400) Subject: drm/radeon: Disable dma rings for bo moves on r6xx X-Git-Tag: firefly_0821_release~6453^2~1164 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d56b0022c1cc6c63ab85f3bebcd8bf3dfe4be5ca;p=firefly-linux-kernel-4.4.55.git drm/radeon: Disable dma rings for bo moves on r6xx 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. Tested-by: J.N.
