[Xen-devel] PV drivers for HVM guest

["Ky Srinivasan" <ksrinivasan@xxxxxxxxxx>]

In platform_pci.c we register the IRQ that the hypervisor should use to notify 
the guest in response to event channel notifications.  In cases where the 
mapping between irq and vectors are not one to one, I am not sure how this can 
work. For instance, on a  RHEL 4 installation (with acpi turned on)  I am 
looking at, the irq assigned to the platform-pci device is 185! Consequently 
the set_callback_irq() fails since the number passed down exceeds the number of 
pins being emulated. Any insight will be greatly appreciated.

Regards,

K. Y
