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
=========
v1 -> v2:
- Revert 2ef6efa79fec ("drm/i915: Improve on suspend / resume
time with VT-d enabled")

In the next couple of patches, we will introduce guard pages around the objects _inside_ the drm_mm_node allocation. That is we will offset the vma->pages so that the first page is at drm_mm_node.start + vma->guard (not 0 as is currently the case). All users must then not use i915_vma.node.start directly, but compute the guard offset, thus all users are converted to use a i915_vma_offset() wrapper. The notable exceptions are the selftests that are testing exact behaviour of i915_vma_pin/i915_vma_insert.

The major consequence is that all ordinary uses of i915_vma must use i915_vma_offset/i915_vma_size and not i915_vma.node.start/size directly, as the drm_mm_node will include the guard pages that surround our object. The biggest connundrum is how exactly to mix requesting a fixed address with guard pages, particularly through the existing uABI. The user does not know about guard pages, so such must be transparent to the user, and so the execobj.offset must be that of the object itself excluding the guard. So a PIN_OFFSET_FIXED must then be exclusive of the guard pages. The caveat is that some placements will be impossible with guard pages, as wrap arounds need to be avoided, and the vma itself will require a larger node. We must not report EINVAL but ENOSPC as these are unavailable locations within the GTT rather than conflicting user requirements. In the next patch, we start using guard pages for scanout objects. While these are limited to GGTT vma, on a few platforms these vma (or at least an alias of the vma) is shared with userspace, so we may leak the existence of such guards if we are not careful to ensure that the execobj.offset is transparent and excludes the guards. (On such platforms like ivb, without full-ppgtt, userspace has to use relocations so the presence of more untouchable regions within its GTT such be of no further issue.)

Currently, we fill the entire GGTT with scratch pages when using VT-d to always ensure there are valid entries around every vma, including scanout. However, writing every PTE is slow as on recent devices we perform 8MiB of uncached writes, incurring an extra 100ms during resume. If instead we focus on only putting guard pages around scanout, we can avoid touching the whole GGTT. To avoid having to introduce extra nodes around each scanout vma, we adjust the scanout drm_mm_node to be smaller than the allocated space, and fixup the extra PTE during dma binding.
