[Xen-devel] [PATCH 1/3] xen/sched: populate cpupool0 only after all cpus are up

2019-08-02 Thread Juergen Gross
With core or socket scheduling we need to know the number of siblings per scheduling unit before we can setup the scheduler properly. In order to prepare that do cpupool0 population only after all cpus are up. With that in place there is no need to create cpupool0 earlier, so do that just before a
