[libvirt] [PATCH 0/4] Improve handling of ppc64 compatibility modes

This series fixes an issue that prevented save / restore from working when using compatibility modes; it also introduces some new checks to make sure the requested compability configuration is actually supported and a few test cases. Cheers. Andrea Bolognani (4): cpu: Don't update host-model guest CPUs on ppc64 cpu: Better support for ppc64 compatibility modes cpu: Move check for NULL CPU model inside the driver tests: Add some compatibility-related cases to the CPU tests src/cpu/cpu.c | 12 --- src/cpu/cpu_generic.c | 6 ++ src/cpu/cpu_ppc64.c | 98 ++++++++++++++++++++-- src/cpu/cpu_x86.c | 6 ++ tests/cputest.c | 14 ++++ .../ppc64-guest-compat-incompatible.xml | 3 + tests/cputestdata/ppc64-guest-compat-invalid.xml | 3 + tests/cputestdata/ppc64-guest-compat-none.xml | 1 + tests/cputestdata/ppc64-guest-compat-valid.xml | 3 + tests/cputestdata/ppc64-guest-host-model.xml | 3 + .../ppc64-host+guest-compat-incompatible.xml | 3 + .../ppc64-host+guest-compat-invalid.xml | 3 + tests/cputestdata/ppc64-host+guest-compat-none.xml | 3 + .../cputestdata/ppc64-host+guest-compat-valid.xml | 3 + tests/cputestdata/ppc64-host+guest-host-model.xml | 3 + .../ppc64-host+guest-legacy-incompatible.xml | 3 + .../ppc64-host+guest-legacy-invalid.xml | 3 + tests/cputestdata/ppc64-host+guest-legacy.xml | 3 + tests/cputestdata/ppc64-host+guest-nofallback.xml | 3 + tests/cputestdata/ppc64-host+guest.xml | 3 + 20 files changed, 162 insertions(+), 17 deletions(-) create mode 100644 tests/cputestdata/ppc64-guest-compat-incompatible.xml create mode 100644 tests/cputestdata/ppc64-guest-compat-invalid.xml create mode 100644 tests/cputestdata/ppc64-guest-compat-none.xml create mode 100644 tests/cputestdata/ppc64-guest-compat-valid.xml create mode 100644 tests/cputestdata/ppc64-guest-host-model.xml create mode 100644 tests/cputestdata/ppc64-host+guest-compat-incompatible.xml create mode 100644 tests/cputestdata/ppc64-host+guest-compat-invalid.xml create mode 100644 tests/cputestdata/ppc64-host+guest-compat-none.xml create mode 100644 tests/cputestdata/ppc64-host+guest-compat-valid.xml create mode 100644 tests/cputestdata/ppc64-host+guest-host-model.xml create mode 100644 tests/cputestdata/ppc64-host+guest-legacy-incompatible.xml create mode 100644 tests/cputestdata/ppc64-host+guest-legacy-invalid.xml create mode 100644 tests/cputestdata/ppc64-host+guest-legacy.xml create mode 100644 tests/cputestdata/ppc64-host+guest-nofallback.xml create mode 100644 tests/cputestdata/ppc64-host+guest.xml -- 2.4.3
