From: Kevin Rogovin <kevin.rogovin@xxxxxxxxx>
This patch series for Mesa defines and uses a new ioctl interface
to get and set the contents of the scratch page for a PPGTT.
The purpose of checking that the scratch page is not changed is
to help detect out-of-bound buffer object writes by the GPU.
v2:
- Correctly change to using GEM_CONTEXT_GET/SETPARAM and thus
make scratch page get/set as per-context
- place checking of scratch page in same location if Mesa/i965
as syncing
Kevin Rogovin (3):
drm-uapi:i915 define set/get (per-context) scratch page ioctl
interface
i965: define gen_debug for checking (per-context) scratch page
i965: implement (per-context) scratch page checking
