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 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 -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaig...> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaig...> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
