[PATCH v3 00/15] drm/i915/gvt: Refine the gtt shadowing

[changbin.du at intel.com]

From: Changbin Du <changbin.du at intel.com>

This is the first part of patch set "drm/i915/gvt: Add support for huge gtt
(2M/64K)". The GTT related code are refined. I just need a clean code base to
add new feature.

This serias has been tested in all three ppgtt modes: aliasing, full and full
with extended address space.

v3: Rebase and improvement.
v2: Some new small patches are created by spliting changes from the two big ones.

  drm/i915/gvt: Rework shadow graphic memory management code
