Hi, hvm_set_callback_irq_level() and so on call vioapic_irq_positive_edge() before spin_unlock(&d->arch.hvm_domain.irq_lock). I think it cause a deadlock. If it is right, how should we fix them? What do you think? Best Regards, Akio Takebe _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
