As found by James Clark, it's not reasonable for the current code for sample flags CPU/TIME/TID which are hard coded. For TIME sample flag, since it's always enabled, then Arm SPE has no chance for timeless tracing; for CPU sample flag, it's not needed for per-thread mode; for TID sample flag, it's redundant for AUX and dummy events. This series corrects the sample flags setting, and it enables timestamp for per-cpu mode tracing by default. This patch set has been tested on Arm64 Hisilicon D06 platform.
