[PATCH v1 0/2] perf cs-etm: Improve timestamp tracing

Posted by Leo Yan 2 years, 3 months ago

This patch series is to improve timestamp handling in per-thread mode.

The current code doesn't validate timestamp and always return success for
per-thread mode, for a sane implementation, the first patch is to allow
validation timestamp tracing in per-thread mode.

The second patch is to respect timestamp option "--timestamp" or "-T",
when users set this option, the tool will automatically enable hardware
timestamp tracing in Arm CoreSight.
