Via implementing ACPI standard methods _EJ0 in ACPI table, after Guest OS remove
one vCPU online, the fireware will store removed bitmap to QEMU, then QEMU could
know to notify the assigned vCPU of exiting. meanwhile, intruduce the QOM
command
'device_del' to remove vCPU from QEMU itself.
This job is based on Chen Fan's previous "cpu-del" patchset:
https://lists.nongnu.org/archive/html/qemu-devel/2013-12/msg04266.html
And it depends on the previous "device_add foo-x86_64-cpu" patchset:
https://lists.nongnu.org/archive/html/qemu-devel/2014-06/msg06690.html
Chen Fan (4):
x86: add x86_cpu_unrealizefn() for cpu apic remove
qom cpu: rename variable 'cpu_added_notifier' to
'cpu_hotplug_notifier'
i386: implement pc interface cpu_common_unrealizefn() in qom/cpu.c
cpu hotplug: implement function cpu_status_write() for vcpu ejection
Gu Zheng (3):
i386: add cpu device_del support
qom cpu: add UNPLUG cpu notify support
cpus: reclaim allocated vCPU objects
