[Intel-gfx] [PATCH 0/2] Handle dma fences in dirtyfb ioctl

[Jouni Högander]

Currently i915 dirtyfb ioctl is not taking dma fences into
account. This works with features like FBC, PSR, DRRS because our gem
code is triggering flush again when rendering completes. We are
targeting in getting rid of frontbuffer tracking code: Flusing hook
from gem code will be removed as well.

This patch set is adding dma fence handling into i915 dirtyfb ioctl.
