X-Git-Tag: microblaze-v5.11~41^2~18^2~121 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=6894305c97ceb56c0caa6f701516546a732af95f;p=linux-2.6-microblaze.git drm/amdgpu: Disable DPC for XGMI for now. XGMI support is more complicated than single device support as questions of synchronization between the device recovering from PCI error and other members of the hive are required. Leaving this for next round.
