H A Dhwlat_detector.rst2 Hardware Latency Detector
24 The hardware latency detector works by hogging one of the cpus for configurable
31 Note that the hwlat detector should *NEVER* be used in a production environment.
55 for every 1,000,000 usecs (1s) the hwlat detector will spin for 500,000 usecs
64 If tracing_thresh was zero when hwlat detector was started, it will be set
66 tracing_thresh that hwlat detector had will be saved and this value will
67 be restored in tracing_thresh if it is still zero when hwlat detector is
81 By default, one hwlat detector's kernel thread will migrate across each CPU
