RE: [Xen-devel] trigger an interrupt in HVM

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

What's the reason to try this? :-)
The interrupt injection into HVM guest doesn't use evtchn_upcall_pending -- 
that's for PV guest.
Maybe you can refer to tools/ioemu/hw/rtl8139.c to see how the rtl8139 device 
model injects interrupt into hvm guest (pls see pci_set_irq()).

Subject: [Xen-devel] trigger an interrupt in HVM

I need to trigger an interrupt on the HVM Xen PCI device. Is this
possible?

Could I just set vcpu_info->evtchn_upcall_pending = 1 and then do a
notify hypercall?

Thanks

James
