How to acquire the occupancy time of CPUs within a certain duration, i.e. 10ms, 1ms, and etc?

[孙世龙 sunshilong]

HI,

Thank you for your reply.

>do you mean make a process exclusively run on a cpu core without being
interrupted/preempted for certain time?
No.
I want to know how long the CPUs are being busy in a specific duration,
e.g: 1ms?

Thank you for your attention to this matter.
