- add '-j' options to filter to enable converting native pmc log format to json lines format to enable the use of scripts and external tooling % pmc filter -j pmc.log pmc.jsonl - Record the tsc value in sampling interrupts as opposed to recording nanotime when the sample is copied to a global log in hardclock - potentially many milliseconds later. - At initialize record the tsc_freq and the time of day to give us an offset for translating the tsc values in callchain records
