[Intel-gfx] [PATCH] drm/i915/gvt: clean up intel_gvt.h as interface for i915 core
Zhenyu Wang
zhenyuw at linux.intel.com
Thu Oct 20 07:29:13 UTC 2016
i915 core should only call functions and structures exposed through
intel_gvt.h. Remove internal gvt.h and i915_pvinfo.h.
Change for internal intel_gvt structure as private handler which
not requires to expose gvt internal structure for i915 core.
