[Intel-xe] [PATCH 0/7] Frontbuffer tracking and dirtyfb

[Jouni Högander]

Generic dirtyfb implementation which Xe is currently using is doing atomic
commit which is inefficient. We have now dma fence handling in our dirtyfb
implementation. This works with Xe and CPU/GPU frontbuffer rendering as
long as sync objects are imported by userspace
(dma_buf_import_sync_file).

This patch set is backporting dirtyfb dma fence handling into our
custom dirtyfb implementation and switching to that on Xe as well.
