Subject: [Intel-gfx] [PATCH v4 2/2] drm/i915/gvt: Add GVT suspend/resume routine to i915
Date: Fri, 16 Oct 2020 14:00:44 +0800 [thread overview]
Message-ID: <20201016060044.296280-1-colin.xu@intel.com> (raw)
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.
