Re: [PATCH PMQA] nohz: check cpus are in nohz mode

check for the timer interrupt raised on cpu for duration of 3 seconds and report the mode

Issues with this approach: - Currently even with NO_HZ_FULL we will get rid of tick only for 1 second - You may also false report idle CPUs here? - There should rather be a sysfs file for reporting this and you can cat that then..

Probably you can grep something from dmesg or kernel boot log to find NO_HZ_FULL CPUs ..
