[Intel-gfx] [PATCH 10/12] drm/i915: Convert execbuf code to use vmas
Ben Widawsky
ben at bwidawsk.net
Mon Jul 22 04:08:17 CEST 2013
This attempts to convert all the execbuf code to speak in vmas. Since
the execbuf code is very self contained it was a nice isolated
conversion.
The meat of the code is about turning eb_objects into eb_vma, and then
wiring up the rest of the code to use vmas instead of obj, vm pairs.
Unfortunately, to do this, we must move the exec_list link from the obj
structure. This list is reused in the shrinker code, so we must also
modify the shrinker code to make this work.
