Don't hack it into the existing sched_credit.c unless you are really sharing significant amounts of stuff (which it looks like you aren't?). sched_bcredit.c would be a cleaner name if there's no sharing. Is a new scheduler necessary -- could the existing credit scheduler be generalised with your boost mechanism to be suitable for both client and server? The issue with multiple schedulers is that it's most likely the non-default will not be tested, used or maintained. The default credit scheduler gets little enough love as it is, and it's really the only sensible scheduler to choose now (SEDF is not great -- good example of a rotten non-default scheduler). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
