Yes it has :) kvm needs data on MSI entries: that's the interface current kernel exposes for injecting these interrupts. I think we also need to support in-kernel devices which would inject MSI interrupt directly from kernel. For these, kvm would need to know when mask bit changes and give us info on pending bit. That's a fair amount of PCI specific code in kvm. -- MST _______________________________________________ Virtualization mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/virtualization
