Hmm. Not along our paths, I think. The only fence-array we have are from sync-file which are signal-on-all (except... in the case of where it wraps a single fence, that fence could be a composite). signal-on-any is icky, to be complete we should not decompose it into its elements - however, whether or not a fence-array is operating in signal_on_any mode is not stored. So at the moment, the best I can do is offer a comment. The only user of it at the moment is amdgpu waiting for the first of many VM manager to become available, not something we'll see immediately via sync-file. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
