[PATCH] drm/i915/gvt: clean up intel_gvt.h as interface for i915 core

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
