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.
v8:
- rebase to latest drm-misc-next, adapt to changes.
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.
please review.
thanks,
Gerd
