I want to change specific parameters of the linux CFS scheduler like the virtual runtime of particular processes dynamically ( vruntime parameter in the sched_entity ). Is there any definite method to do this? I have already looked at commands like nice() and it won't serve the purpose.
As far as I know, we can't change the vruntime, since it is maintained per task basis. Instead can check the current task's vruntime and other values per CPU basis, by issuing the below command "#cat /proc/sched_debug"
