From 81a8aa4a6c8535955c8b795c762489d0edf9a648 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 15 Aug 2016 10:48:48 +0100 Subject: [PATCH] drm/i915: Create a VMA for an object In many places, we wish to store the VMA in preference to the object itself and so being able to create the persistent VMA is useful.
