Hello,
Came across below code excerpt in x86/microvm code and wanted to know
why 'has_hotpluggable_cpus' flag has been set to 'false' while various
hot(un)plug APIs have been defined?
static void microvm_class_init(ObjectClass *oc, void *data)
{
X86MachineClass *x86mc = X86_MACHINE_CLASS(oc);
MachineClass *mc = MACHINE_CLASS(oc);
HotplugHandlerClass *hc = HOTPLUG_HANDLER_CLASS(oc);
mc->init = microvm_machine_state_init;
mc->family = "microvm_i386";
[...]
mc->max_cpus = 288;
mc->has_hotpluggable_cpus = false; --------> This one
[...]
/* hotplug (for cpu coldplug) */
mc->get_hotplug_handler = microvm_get_hotplug_handler;
hc->pre_plug = microvm_device_pre_plug_cb;
hc->plug = microvm_device_plug_cb;
hc->unplug_request = microvm_device_unplug_request_cb;
hc->unplug = microvm_device_unplug_cb;
[...]
}
Best regards
Salil
