You mean it tries to qualesce fences in the same context down to just the last one? That's how it's supposed to be done, and fence_collections do break this somewhat. Without fixing up fence_is_later and friends. Sounds like amdgpu is a good use case to make sure the changes in semantics in these functions result in sensible code. In a way a fence_collection is a fence where the timeline never matches with any other timeline (since it's a combiation). And yeah I think fence_collection should probably compress down the fences to 1 per timeline. But then that's just an implementation detail we can fix later on. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
