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. On Fri, Sep 4, 2020 at 11:59 AM Mulyadi Santosa <mulyadi.santosa@gmail.com> wrote:

Hi, list

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. Sunshilong

Hi

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