[PATCH 04/29] drm/i915: Use bound list for inactive shrink

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

 



Do to the move active/inactive lists, it no longer makes sense to use
them for shrinking, since shrinking isn't VM specific (such a need may
also exist, but doesn't yet).

What we can do instead is use the global bound list to find all objects
which aren't active.
