For measuring latency in modern systems, we need to be able to measure intervals in microseconds at least, and preferably in nanoseconds or better. The good news is that with relatively modern hardware and software, it is possible to accurately measure time intervals as small as (some smallish number of) …

WebMay 3, 2015 · Clocksource tsc was the one being used. Then I tried acpi=off option and found that there were only two clocksources, tsc jiffies. However, tsc was not unstable and still used as the main clocksource. Therefore the watchdog jiffies will not always deny tsc. I did the above experiment on a Dell desktop.
