Re: [Xen-devel] xenpm and scheduler



Thanks Xu. I will do as desired about cross messaging.

i need it because i exactly want to know that which part of the scheduler's 
corde (credit), takes effect from this feature. because it is important to me 
knowing that where would be trade off between idle state and doing load 
balancing, while cpuidle feature is activated. in other side it's important 
again for me that what will happen for 'cap; and 'weight' decreasing in a case 
that one core's frequency is lower than another one in the same socket 
(actually when cpufreq feature is enable).

Am i clear enough? can you give me an answer or maybe some lines of schedule.c 
or sched_credit.c's code which i can track them to notice the effect of xenpm 
on scheduler part of the view?

Thanks a lot.  
Regards.

hi,
Does xenpm 'cpufreq' or 'cpuidle' feature, has any effect on scheduling 
decisions?




​Please do not cross post. 


 

No effect on RTDS scheduler. 


 

May I ask a question: why do you need to consider this? 


 

Thanks,
