Revision e3818697e1d9140d0b990fecf4429d40c41ca0b5 authored by Chris Wilson on 09 January 2017, 11:19:32 UTC, committed by Jani Nikula on 08 February 2017, 11:10:24 UTC
On a non-llc system, the objects are created with .cache_level = CACHE_NONE and so the transition to uncached for scanout is a no-op. However, if the object was never written to, it will still be in the CPU domain (having been zeroed out by shmemfs). Those cachelines need to be flushed prior to display.
