Hi.. I was going through wiki page of Credit Scheduler which says - " The scheduling decision is the common path of the scheduler and is therefore designed to be light weight and efficient. No accounting takes place in this code path. " So where does the accounting process takes place. exctaly by which way accounting for CPU, different IO device usage is done. With the complex architecture of Xen, how does this accounting process is carried out?
The credit scheduler sets up a timer when it is initialized. It does process accounting during the timer service routine. The decision to schedule the next vcpu is done on a different code path, and is optimized to be as fast as possible. Mike -- Mike D.
