Hi
Please consider these two new perf features:
x86: add ability to calculate TSC from perf sample timestamps
perf: add 'keep tracking' flag to PERF_EVENT_IOC_DISABLE
This is also a minor fix:
perf: fix broken union in perf_event_mmap_page
And tests in perf tools:
perf tools: add test for converting perf time to/from TSC
perf tools: add 'keep tracking' test
