[Intel-gfx] [PATCH V3 1/3] drm/i915: Wrap all access to i915_vma.node.start|size
Tejas Upadhyay
tejaskumarx.surendrakumar.upadhyay at intel.com
Thu Feb 24 10:52:44 UTC 2022
From: Chris Wilson <chris at 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.
Changes since V2 :
- Rebased on drm-tip
