In CFS scheduler, it always picks a process with minimum vruntime. vruntime of a running process is increased by the amount of CPU it consumes.
I have following two questions related to CFS and vruntime.
When multiple processes/threads are newly created, what is the initial vruntime of newly created process/thread ? Is the minimum vruntime in that ready queue at that time of creation or something else ?
If one process is there which has already ran for long and its vruntime is already high, in that scenario a new process is created. Now what will be the initial vruntime of newly created process ( keeping is mind the maximum unfairness ).
