[Qemu-devel] [PATCH 0/3 RFC] add PCI support for the s390 platform

[Frank Blaschka]

This set of patches implemets PCI support for the s390 platform.
Now it is possible to run virtio-net-pci and potentially all
virtual pci devices conforming to s390 platform constrains.
(In parallel I also post some changes to make vfio run on s390)

I hope to get feedback and guidance especially for

kvm: extend kvm_irqchip_add_msi_route to work on s390

which adds the s390 interpretation of MSI-X to the common kvm
add_msi_route functionality.

Thx for any help,

Frank
