ttm increasingly gets into the way while hacking on virtio-gpu memory management. It also overkill for what virtio-gpu needs. Lets get rid of it.
v7: - rebase to latest drm-misc-next - reorder patches: switch all virtio commands to object array helpers first. then drop ttm, to make sure we don't release objects still in use. - misc fixes. v6: - largely rewrite fencing logic, using the virtio_gpu_array_* helpers - add more patches to the series. v5: - fence bugfixes. - minor optimizations. v4: - make gem array helpers private to virtio. - misc minor fixes. v3: - add gem array helpers. - rework fencing.
cheers, Gerd
