[PATCH 1/2] kvm/x86: Hyper-V synthetic interrupt controller
...nd route for > the same irqchip via flic, which will also be of type > KVM_IRQ_ROUTING_S390_ADAPTER. Correct? It's a bit different. The kernel basically does not see msi routes for s390 pci at all, as qemu already transforms the msi route into an adapter route before registering it (see kvm_arch_fixup_msi_route() in qemu's target-s390x/kvm.c). So, in the end, all s390 kernels end up using adapter routes, and none of them are duplicate (just one irqchip). Going back to Paolo's original question, I think changing the check to !KVM_IRQ_ROUTING_IRQCHIP makes sense, if I understand the code correctly...
