This set of patches implements a vfio based solution for pci
pass-through on the s390 platform. The kernel stuff is pretty
much straight forward, but qemu needs more work.
Most interesting patch is:
vfio: make vfio run on s390 platform
I hope Alex & Alex can give me some guidance how to do the changes
in an appropriate way. After creating a separate iommmu address space
for each attached PCI device I can successfully run the vfio type1
iommu. So If we could extend type1 not registering all guest memory
(see patch) I think we do not need a special vfio iommu for s390
for the moment.
The patches implement the base pass-through support. s390 specific
virtualization functions are currently not included. This would
be a second step after the base support is done.
kernel patches apply to linux-kvm-next
KVM: s390: Enable PCI instructions
iommu: add iommu for s390 platform
vfio: make vfio build on s390
qemu patches apply to qemu-master
s390: Add PCI bus support
s390: implement pci instruction
vfio: make vfio run on s390 platform
Thx for feedback and review comments
