Hi,
This series adds guards around vma's but setting a pages at the
beginning and at the end that work as padding.
The first user of the vma guard are scanout objects which don't
need anymore to add scratch to all the unused ggtt's and speeding
up up considerably the boot and resume by several hundreds of
milliseconds up to over a full second in slower machines.
Because of this we don't need anymore 2ef6efa79fec ("drm/i915:
Improve on suspend / resume time with VT-d enabled") which gets
reverted.
Changelog
