What is the exact use of ioport_permit_access() and irq_permit_access() kind of functions? If I permit port/irq access to HVM guest for a particular port or IRQ, does that mean guest VCPU does not issue a hypercall when accessing them? If a PIRQ is asserted by physical hardware, can hvm guest directly get notification if given such access? Thanks Jayant _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
