Hi!
Let me add my 0.2 cents to this discussion by sharing my summary of INTx
emulation in VFIO:
COMMON:
* real interrupt is signaled in the kernel
* vfio-pci kernel interrupt hanlder (vfio_intx_handler), masks the INTx flag
* vfio-pci kernel interrupt handler triggers an eventfd, if the

Hello Paolo, Alex and all,
In vfio_intx_enable_kvm(qemu) I see we associate a resamplefd with the
umask function(vfio_pci_intx_unmask_handler in linux).
irq_set = g_malloc0(argsz);
irq_set->argsz = argsz;
irq_set->flags = VFIO_IRQ_SET_DATA_EVENTFD | VFIO_IRQ_SET_ACTION_UNMASK;
