When DMAR / VT-d is enabled, the display engine uses overfetching, presumably
to deal with the increased latency. To avoid display engine errors and DMAR
faults, as a workaround the GGTT is populated with scatch PTEs when VT-d
is enabled. However starting with gen10, Write-combined writing of scratch
PTES is no longer possible and as a result, populating the full GGTT with
scratch PTEs like on resume becomes very slow as uncached access is needed.
Therefore, replace filling the GGTT entirely with scratch pages with only
filling surrounding scanout vma with guard pages. This eliminates the 100+ms
delay in resume where we have to repopulate the GGTT with scratch.
While 100+ms might appear like a short time it's 10% to 20% of total resume
time and important in some applications.
Additional considerations:
Since GPUs where VT-d might be present should have at least 2GiB worth of
GGTT space, the extra guard pages should not really have a significant
impact on GGTT contention.
Neither should there be a problem with not populating GGTT with scratch
PTEs on unbind since that's typically not done when VT-d is not enabled
either.
Finally, discrete GPUs should ideally not overfetch even with VT-d enabled,
but removing the workaround for discrete GPUs needs thorough testing and
will be done, if needed, as a follow up.
Patch 1 introduces accessors for vma.node.start and vma.node.size. While
this patch is the most invasive, the end result is actually something
we might want event without the introduced guard pages.
Patch 2 introduces the concept of guard pages to i915_vma and wraps the
needed arithmetic in the accessors.
Patch 3 uses the guard pages to replace the old VT-d workaround.
v4: Completely rebase on drm-tip:
- Avoid vmas in the binding backends
- Make sure vma PIN flags don't clash
- Add some kernedoc and rewrite cover-letter.

* [PATCH v4 1/3] drm/i915: Wrap all access to i915_vma.node.start|size

Tejas Upadhyay
From: Chris Wilson <chris@chris-wilson.co.uk>
We already wrap i915_vma.node.start for use with the GGTT, as there we
can perform additional sanity checks that the node belongs to the GGTT
and fits within the 32b registers. 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.
v2:
- Rebased on drm-tip.
v3:
- Rebase on drm-tip reworked. The vma resources still used for the
vm backend interface, but the meaning of start and node_size updated.
Documentation update.

* [Intel-gfx] [PATCH v4 1/3] drm/i915: Wrap all access to i915_vma.node.start|size
@ 2022-03-23 8:35 ` Thomas Hellström
0 siblings, 0 replies; 13+ messages in thread
From: Thomas Hellström @ 2022-03-23 8:35 UTC (permalink / raw)
To: intel-gfx
Cc: Thomas Hellström, dri-devel, Chris Wilson, matthew.auld,
Tejas Upadhyay, airlied
From: Chris Wilson <chris@chris-wilson.co.uk>
We already wrap i915_vma.node.start for use with the GGTT, as there we
can perform additional sanity checks that the node belongs to the GGTT
and fits within the 32b registers. 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.
v2:
- Rebased on drm-tip.
v3:
- Rebase on drm-tip reworked. The vma resources still used for the
vm backend interface, but the meaning of start and node_size updated.
Documentation update.

* [PATCH v4 2/3] drm/i915: Introduce guard pages to i915_vma

From: Chris Wilson <chris@chris-wilson.co.uk>
Introduce the concept of padding the i915_vma with guard pages before
and aft. 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 we 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.)
v2: Include the guard range in the overflow checks and placement
restrictions.
v3: Fix the check on the placement upper bound. The request user offset
is relative to the guard offset (not the node.start) and so we should
not include the initial guard offset again when computing the upper
bound of the node.
v4:
- Rebase on upstream vma resources.
- Use iowrite32 instead of gen8_set_pte() in gen6_ggtt_insert_entries()

* [PATCH v4 3/3] drm/i915: Refine VT-d scanout workaround

From: Thomas Hellström @ 2022-03-23 8:35 UTC (permalink / raw)
To: intel-gfx; +Cc: Tejas Upadhyay, matthew.auld, dri-devel, Chris Wilson
From: Chris Wilson <chris@chris-wilson.co.uk>
VT-d may cause overfetch of the scanout PTE, both before and after the
vma (depending on the scanout orientation). bspec recommends that we
provide a tile-row in either directions, and suggests using 168 PTE,
warning that the accesses will wrap around the ends of the GGTT.
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.
