[Intel-gfx] gpu outputs slave and cache flushing

2013-07-29 Thread Dave Airlie
Hey, so I put a patch into intel driver a while ago to avoid doing a bo flush using map/unmap for output slave device if the kernel has vmap flushing However on reflection I realised this only works for CPU accessing devices like UDL but doesn't work for GPU accessing devices like nouveau/radeon,
