From 385fc38c1f97387c47113254d8de2cb0dbf133bd Mon Sep 17 00:00:00 2001 From: Colin Xu Date: Tue, 27 Oct 2020 12:54:06 +0800 Subject: drm/i915: Add GVT resume routine to i915 This patch add gvt resume wrapper into i915_drm_resume(). GVT relies on i915 so 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. V6: Save host entry to per-vGPU gtt.ggtt_mm on each host_entry update so only need the resume routine. V7: Refresh.
