Subject: drm/radeon: use DMA engine for VM page table updates on SI
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bf66a786c92488dfc99cc7f19bc9eda7b4c98fa6;p=linux-beck.git

drm/radeon: use DMA engine for VM page table updates on SI

DMA engine has special packets to facilitate this and it also keeps
