Subject: [Qemu-devel] [PATCH 0/8] [PATCH RFC v2] s390-qemu: cpu hotplug
Date: Fri, 7 Jun 2013 13:27:59 -0400 [thread overview]
Message-ID: <1370626087-840-1-git-send-email-jjherne@us.ibm.com> (raw)
Latest code for cpu Hotplug designed to be controled via the QOM infrastructure.
cpu on S390 are treated as devices via a new platform independent
infrastructure I designed to allow this "new way" to exist with the "old way"
of representing cpus.
The Qemu command line now allows "-device s390-cpu" which will instantiate a
cpu device. This is additive to anything that might be specified on the -smp
parameter.
Devices can be hot plugged via the monitor command "device_add s390-cpu".
Hotplugged cpus are created in the configured state and can be used by the
guest after the guest onlines the cpu by:
"echo 1 > /sys/bus/cpu/devices/cpuN/online"
Hot unplugging is currently not implemented by this code.
