Subject: [PATCH 0 of 2] Scheduler: Implement yield for credit scheduler
Date: Mon, 9 Aug 2010 12:20:49 +0100 [thread overview]
Message-ID: <patchbomb.1281352849@gdunlap-desktop> (raw)
As discussed in a previous e-mail, this patch series implements yield
for the credit scheduler. This allows a VM to actually yield (give up
the cpu to another VM) when it wants to. This has been shown to be
effective when used in the spinlock code to avoid wasting time
spinning when another vcpu is not currently scheduled.
