From: Chris Wilson Date: Tue, 22 Aug 2017 11:05:15 +0000 (+0100) Subject: drm/i915: Assert the context is not closed on object-close X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=432295d7b906dae11129fc2870289465c907e5f2;p=linux.git drm/i915: Assert the context is not closed on object-close During the context-close, we should be decoupling all the vma from the object so that upon object-closing we shouldn't see any vma from the already closed contexts. So include a check upon closing the object that the context is still open. v2: Eek, the fpriv check is required for shared objects. Double eek, BAT passed?
