Re: [Xen-devel] [RFC][PATCH] scheduler: credit scheduler for client virtualization



Thank you for your comment.

I'll try to be suitable for both server and client.

Regards,
Naoki Nishiguchi

Please review this patch.
Any comments are appreciated.

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).
