| |
Thi patch series fixes up hwlat-detector to check the entire path of time for a latency being hit, instead of the quick check between two time stamps.
It also uses the trace_local_clock() if available, which is much lighter weight than ktime_get() which might produce false positives. As the trace clock is used to detect irq latencies, it's suitable for hardware latency.
Finally, stop machine is removed and the test is run by a single thread.
