[Qemu-devel] [PATCH v3 0/9] s390x: zPCI detangling

[Cornelia Huck]

Next version, now without RFC. The goals are still the same:
- Being able to disable PCI support in a build completely.
- Properly fencing off PCI if the relevant facility bit is not provided.

Changes v2->v3:
- Only enable the zpci bit conditionally, keep the aen bit always on.
  Use a method that actually works...
- Some reordering in the msi route patch to keep the change small.
- Collected some r-bs.

Branch is still git://github.com/cohuck/qemu no-zpci-cpumodel

Likely 2.11 material, even though the 'fence off if facility bit is not
set' part could count as bugfixes. Thoughts?

Cornelia Huck (9):
  kvm: remove hard dependency on pci
  s390x/pci: add stubs
  s390x: chsc nt2 events are pci-only
  s390x/pci: do not advertise pci on non-pci builds
  s390x/ccw: create s390 phb conditionally
  s390x/sclp: properly guard pci-specific functions
  s390x/pci: fence off instructions for non-pci
  s390x/kvm: msi route fixup for non-pci
  s390x: refine pci dependencies
