I mean, is there an API that guarantees high precision (non architecture dependent way) Thanks! 2021년 5월 2일 (일) 오후 11:54, Greg KH <greg@kroah.com>님이 작성:

the 'timer wheel' - which has low resolution works at jiffy resolution. so usually it has precision of 1~10ms.
and there's high resolution timers in kernel to have nanosecond resolution, but it doesn't seem to have nanosecond precision
is there a way to deal with high precision timers in kernel?
What exactly are you needing here? And do you have hardware that provides both high precision and high resolution?
thanks,
