Thanks David,
Initially I thought we could run into wait issues with a dma_fence_chain
with a value = 0, but you're right, it works fine.
We could just avoid to create a dma_fence_chain object, but maybe we
don't care.

Sorry for late response.
Although we don't expect that, drm_syncobj_timeline_signal_ioctl
already handle this case I think. Which can handle both (point value >
0) and (point value = 0).

Hi all,
While picking up the IGT tests for timeline syncobj,
I noticed that although we deal with multi wait across both timeline
(with point value > 0) and binary (point value = 0) syncobjs,
we don't seem to have a similar behavior with signaling.
Do you have any thought on this?
I'm considering writing some docs but I'm not quite sure whether this
difference between signaling/waiting was intentional or just
overlooked.
Thanks,
