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. -Lionel On 21/05/2019 09:51, zhoucm1 wrote: Sorry for late response.

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 consider
