These functions make the internal s390 cpu model API independent from a
specific accelerator:
int s390_set_processor_props(S390ProcessorProps *prop)
{
if (kvm_enabled()) {
return kvm_s390_set_processor_props(prop);
}
return -ENOSYS;
}
It's called by:
s390_select_cpu_model(const char *model)
which is itself called by:
S390CPU *cpu_s390x_init(const char *cpu_model)
{
S390CPU *cpu;
cpu = S390_CPU(object_new(s390_select_cpu_model(cpu_model)));
object_property_set_bool(OBJECT(cpu), true, "realized", NULL);
return cpu;
}
So above s390_set/get_processor_props() the code is accelerator independent.
