[Xen-devel] question about hvm vhpet

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

I'm a bit confused whether vhpet is enabled by default or not.

Per 17017, changelog says vhpet disabled by default, but the code
conflicts as below:
@@ -231,6 +231,8 @@ int hvm_domain_initialise(struct domain
     spin_lock_init(&d->arch.hvm_domain.pbuf_lock);
     spin_lock_init(&d->arch.hvm_domain.irq_lock);
     spin_lock_init(&d->arch.hvm_domain.uc_lock);
+
+    d->arch.hvm_domain.params[HVM_PARAM_HPET_ENABLED] = 1;

Then if config file for hvm domain has no explicit 'hpet=0/1' option,
will xend issue a hypercall to set vhpet to '0' or the latter will be
left as '1'?

Thanks,
Kevin
