[Intel-gfx] [PATCH v2 0/2] Enable GVT suspend/resume

[Colin Xu]

This patchset enables GVT suspend/resume so that GVT enabled VM can
continue running after host resuming from suspend state.

V2:
- Change kzalloc/kfree to vzalloc/vfree since the space allocated
from kmalloc may not enough for all saved GGTT entries.
- Keep gvt suspend/resume wrapper in intel_gvt.h/intel_gvt.c and
move the actual implementation to gvt.h/gvt.c. (zhenyu)
- Check gvt config on and active with intel_gvt_active(). (zhenyu)

Colin Xu (2):
  drm/i915/gvt: Save/restore HW status for GVT during suspend/resume
  drm/i915/gvt: Add GVT suspend/resume routine to i915
