[Qemu-devel] [PATCH v4 0/4] tests: enable ohci/uhci/xhci tests on PPC64

[Laurent Vivier]

This series enables USB tests on PPC64, and for
that implements libqos SPAPR PCI support.

v4:
- rebase on ppc-for-2.8
- move endianness management in pci-spapr.c
  and remove the two useless patches managing that
- Add David's R-b

v3:
- rebase
- minor fixes (commas, comments)
- add Greg's R-b

v2:
- rebase
- revert order in qtest_common_shutdown() to release
  PCI and then memory allocator
- remove useless byte-swapping in qpci-spapr.c
- compute machine endianness on qtest_init()
- introduce target_cpu_to_leXX()/target_cpu_to_beXX()
            target_leXX_to_cpu()/target_beXX_to_cpu()

Laurent Vivier (4):
  libqos: add PPC64 PCI support
  libqos: add PCI management in qtest_vboot()/qtest_shutdown()
  libqos: use generic qtest_shutdown()
  tests: enable ohci/uhci/xhci tests on PPC64

[Qemu-devel] [PATCH v4 3/4] libqos: use generic qtest_shutdown()

[Laurent Vivier]

Machine specific shutdown function can be registered by
the machine specific qtest_XXX_boot() if needed.

So we will not have to test twice the architecture (on boot and on
shutdown) if the test can be run on several architectures.
