This patch add gvt suspend/resume wrapper into i915: i915_drm_suspend() and i915_drm_resume(). GVT relies on i915 so suspend gvt ahead of other i915 sub-routine and resume gvt at last. V2: - Direct call into gvt suspend/resume wrapper in intel_gvt.h/intel_gvt.c. The wrapper and implementation will check and call gvt routine. (zhenyu) V3: Refresh. V4: Rebase. V5: Fail intel_gvt_suspend() if fail to save GGTT.
