Yes indeed. We're now able to see in simulation that if a userspace process uses 100% CPU, its thread ID, rather than what was usually some random kthread, gets written out most of the time. I donno if that meets your criteria for a "real" use case, but I hope it's at least sufficient testing of the code for now. Thanks, Christopher -- Employee of Qualcomm Innovation Center, Inc.
