Hi, all I noticed followed statement about TSC timer on https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO , " Since the TSC timer on PC platforms, as used in the previous versions, are now marked as unsuitable for hrt mode due to many lacks of functionalities and reliabilities, you will need i.E. pm_timer as provided by ACPI to use as clock source". I'm testing on Intel Xeon CPU E5-2640 and has "Switched to clocksource tsc" on kernel log, I think it mean the TSC on my system is stable and reliable enough to use as clock source, right? With the invariant and synchronized TSC support in latest hardware, can I assume generally TSC would be better than pm_timer?
