[Xen-devel] A question on the credit scheduler

[zhikai <gbtux@xxxxxxx>]

Hi All,

In the credit scheduler, the scheduling decision function csched_schedule() is called in the schedule function in scheduler.c, such as the following.

next_slice = sched->do_schedule(sched, now, tasklet_work_scheduled);

But, how often the csched_schedule() is called and to run? Does this frequency have something to do with the slice of credit scheduler that is 30ms?

Best Regards,

Gavin
