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.

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

Could somebody please shed some light on this matter?
I would be grateful to have some help with this question.

Best Regards.

Hi

do you mean make a process exclusively run on a cpu core without being interrupted/preempted for certain time?

if yes, i think schedule a process as real time (sched fifo?), create timer, sched yield after timer runs out. cmiiw
