* [PV-ON-HVM] Don't generate lots of spurious interrupts when using eventSteven Smith2006-10-311-1/+7
| | | | | | | | | | | | | | | | | | channel upcalls. The issue here was that the Xen platform PCI interrupt is only updated when you return from the hypervisor into guest context, and so remained asserted for a short interval after the interrupt handler ran. If it happened that the first subsequent trap to the hypervisor was for unmasking the 8259 interrupt again, the unmasking caused the interrupt to be reinjected. This caused an edge on the chaining interrupt from the slave PIC to the master. The platform interrupt on the slave would then be cleared as we returned to the guest, and so you eventually end up injecting an interrupt on the master chained interrupt with nothing pending on the slave, which shows up as a spurious interrupt in the guest.
