On 02.08.19 15:07, Juergen Gross wrote: These three patches have been carved out from my core scheduling series as they are sufficiently independent to be applied even without the big series. Without this little series there are messages like the following to be seen on the console when booting with smt=0: (XEN) Adding cpu 1 to runqueue 0 (XEN) CPU 1 still not dead... (XEN) CPU 1 still not dead... (XEN) CPU 1 still not dead... (XEN) CPU 1 still not dead... By assigning cpus to Cpupool-0 only after all cpus are up and by not using the more complicated credit2 scheduler for cpus not in any cpupool this situation can simply no longer happen, as parking the not to be started threads is done before. Juergen Gross (3): xen/sched: populate cpupool0 only after all cpus are up xen/sched: remove cpu from pool0 before removing it xen/sched: add minimalistic idle scheduler for free cpus Would it be possible to have some feedback on this series?
