From: Chris Wilson Date: Sun, 18 Dec 2016 15:37:22 +0000 (+0000) Subject: drm/i915: Mark the shadow gvt context as closed X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=70ffe9956c5cf328380053c803b783df711e8024;p=linux-beck.git drm/i915: Mark the shadow gvt context as closed As the shadow gvt is not user accessible and does not have an associated vm, we can mark it as closed during its construction. This saves leaking the internal knowledge of i915_gem_context into gvt/.
