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, Going forward I'm sure we'll eventually get GPU sync via Maarten's patches but I'm thinking I should revert this change in the intel driver for now, so reverse optimus can work properly Anyone got any ideas for a better plan going forward, maybe a stop gap before Maartens patches.
