(mistakenly put a wrong message id in "In-reply-To") Acked-by: Dongwon Kim <dongwon.kim@xxxxxxxxx> It makes lots of sense to make CPU cache operation done only when needed. Similar change was already landed in drm-prime and other vendor specific drivers. We are actually seeing huge performance boost in a specific customer case where dmabuf was used between camera driver (importer) and i915 after applying this patch. Please consider upstreaming this code change. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
