[Intel-gfx] [PATCH 0/3] RFC: v2 set/get scratch page contents

[kevin.rogovin at intel.com]

From: Kevin Rogovin <kevin.rogovin at intel.com>

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
