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.
Thanks Tvrtko and Chris for the review.
Andi
Changelog
=========
v3 -> v4:
- change the order of the patches: the 64->32 bit change of the
memory alignment goes as first (Tvrtko).
- Use roundup instead of ALIGN to round up the guard padding
(Chris).
- Restore the GEM_BUG_ON(2 * guard > end) as a paranoiac check
and as mean of documentation (Chris).
v2 -> v3:
- fix Tvrtko's comments: explain in a comment why the guard is
is alligned as the vma and remove a GEM_BUG_ON() in case the
the total padding was exceeding the size of the va.
- the display_alignment is declared as u32 instead of a u64 in
a separate patch.
v1 -> v2:
- Revert 2ef6efa79fec ("drm/i915: Improve on suspend / resume
time with VT-d enabled")
