[PATCH 0 of 3] xen: sched_credit: fix tickling and add some tracing
Hello,
This small series deals with some weirdness in the mechanism with which the
credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are
available in the changelog of the first patch.
The new approach has been extensively benchmarked and proved itself either
beneficial or harmless. That means it does not introduce any significant amount
of overhead and/or performances
