[PATCH 11/19] drm/i915: Track pinned VMA

Chris Wilson chris at chris-wilson.co.uk
Sat Aug 6 14:46:17 UTC 2016


Treat the VMA as the primary struct responsible for tracking bindings
into the GPU's VM. That is we want to treat the VMA returned after we
pin an object into the VM as the cookie we hold and eventually release
when unpinning. Doing so eliminates the ambiguity in pinning the object
and then searching for the relevant pin later.
