Hi, Just to warn any by passer who might want to review the remaining patches: there are changes in the QEMU side that we would like to make that would make the proposed support here simpler. The planned changes are: - add virtual pnv-phb and pnv-phb-root-port devices. These virtual devices will not be versioned and will be used in all PowerNV machines (powernv8/9/10), meaning that we wouldn't need to add a pnv-phbN/pnv-phbN-root-port pair for each machine; - this new virtual device will have its own capability (QEMU_CAPS_DEVICE_PNV_PHB), which will also simplify what we're doing here - we won't need to snapshot an specific QEMU version that happened to have user creatable PHBs. Most of the already reviewed code will be used in the next version. As soon as the 7.1 support is upstream I'll reroll this series with these changes.

Hi, This new version contains changes proposed by Jano. The most notable change is on patch 9, where pnv_pnv3/pnv_phb4 capabilities are now being probed and, if the QEMU version isn't high enough, they are cleared from qemuCaps. For convenience, the patches that are pending review/acks are patches 14, 17, 19, 20, 22, 23 and 24. v2 link: https://listman.redhat.com/archives/libvir-list/2022-January/msg01149.html Daniel Henrique Barboza (29): qemu_domain.c: add PowerNV machine helpers qemu_capabilities.c: use 'MachineIsPowerPC' in DeviceDiskCaps qemu_domain: turn qemuDomainMachineIsPSeries() static qemu_validate.c: use qemuDomainIsPowerPC() in qemuValidateDomainChrDef() qemu_domain.c: define ISA as default PowerNV serial qemu_validate.c: enhance 'machine type not supported' message qemu_domain.c: disable default devices for PowerNV machines tests: add basic PowerNV8 test qemu: introduce QEMU_CAPS_DEVICE_PNV_PHB3 conf, qemu: add 'pnv-phb3-root-port' PCI controller model name conf, qemu: add 'pnv-phb3' PCI controller model name domain_conf.c: fix identation in virDomainControllerDefParseXML() conf: parse and format <target chip-id='...'/> formatdomain.rst: add 'index' semantics for PowerNV domains conf: introduce virDomainControllerIsPowerNVPHB conf, qemu: add default 'chip-id' value for pnv-phb3 controllers conf, qemu: add default 'targetIndex' value for pnv-phb3 devs qemu_command.c: add command line for the pnv-phb3 device qemu_domain_address.c: change pnv-phb3 minimal downstream slot domain_conf: always format pnv-phb3-root-port address tests: add pnv-phb3-root-port test domain_validate.c: allow targetIndex 0 out of idx 0 for PowerNV PHBs domain_conf.c: reject duplicated pnv-phb3 devices qemu: introduce QEMU_CAPS_DEVICE_PNV_PHB4 conf, qemu: add 'pnv-phb4-root-port' PCI controller model name domain_conf.c: add phb4-root-port to IsPowerNVRootPort() conf, qemu: add 'pnv-phb4' controller model name domain_conf.c: add pnv-phb4 to ControllerIsPowerNVPHB() tests: add PowerNV9 tests docs/formatdomain.rst | 12 +- docs/schemas/domaincommon.rng | 10 ++ src/conf/domain_conf.c | 156 ++++++++++++++---- src/conf/domain_conf.h | 8 + src/conf/domain_validate.c | 5 +- src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 19 ++- src/qemu/qemu_capabilities.h | 4 + src/qemu/qemu_command.c | 21 ++- src/qemu/qemu_domain.c | 51 +++++- src/qemu/qemu_domain.h | 4 +- src/qemu/qemu_domain_address.c | 64 ++++++- src/qemu/qemu_validate.c | 62 ++++++- .../qemucapabilitiesdata/caps_5.0.0.ppc64.xml | 2 + .../qemucapabilitiesdata/caps_5.2.0.ppc64.xml | 2 + .../qemucapabilitiesdata/caps_6.2.0.ppc64.xml | 2 + .../qemucapabilitiesdata/caps_7.0.0.ppc64.xml | 2 + .../powernv8-basic.ppc64-latest.args | 34 ++++ tests/qemuxml2argvdata/powernv8-basic.xml | 16 ++ tests/qemuxml2argvdata/powernv8-dupPHBs.err | 1 + .../powernv8-dupPHBs.ppc64-latest.err | 1 + tests/qemuxml2argvdata/powernv8-dupPHBs.xml | 27 +++ .../powernv8-root-port.ppc64-latest.args | 35 ++++ tests/qemuxml2argvdata/powernv8-root-port.xml | 17 ++ .../powernv8-two-sockets.ppc64-latest.args | 35 ++++ .../qemuxml2argvdata/powernv8-two-sockets.xml | 26 +++ .../powernv9-dupPHBs.ppc64-latest.err | 1 + tests/qemuxml2argvdata/powernv9-dupPHBs.xml | 27 +++ .../powernv9-root-port.ppc64-latest.args | 35 ++++ tests/qemuxml2argvdata/powernv9-root-port.xml | 17 ++ tests/qemuxml2argvtest.c | 7 + .../powernv8-basic.ppc64-latest.xml | 34 ++++ .../powernv8-root-port.ppc64-latest.xml | 39 +++++ .../powernv8-two-sockets.ppc64-latest.xml | 39 +++++ .../powernv9-root-port.ppc64-latest.xml | 39 +++++ .../qemuxml2xmloutdata/powernv9-root-port.xml | 36 ++++ tests/qemuxml2xmltest.c | 5 + 37 files changed, 848 insertions(+), 48 deletions(-) create mode 100644 tests/qemuxml2argvdata/powernv8-basic.ppc64-latest.args create mode 100644 tests/qemuxml2argvdata/powernv8-basic.xml create mode 100644 tests/qemuxml2argvdata/powernv8-dupPHBs.err create mode 100644 tests/qemuxml2argvdata/powernv8-dupPHBs.ppc64-latest.err create mode 100644 tests/qemuxml2argvdata/powernv8-dupPHBs.xml create mode 100644 tests/qemuxml2argvdata/powernv8-root-port.ppc64-latest.args create mode 100644 tests/qemuxml2argvdata/powernv8-root-port.xml create mode 100644 tests/qemuxml2argvdata/powernv8-two-sockets.ppc64-latest.args create mode 100644 tests/qemuxml2argvdata/powernv8-two-sockets.xml create mode 100644 tests/qemuxml2argvdata/powernv9-dupPHBs.ppc64-latest.err create mode 100644 tests/qemuxml2argvdata/powernv9-dupPHBs.xml create mode 100644 tests/qemuxml2argvdata/powernv9-root-port.ppc64-latest.args create mode 100644 tests/qemuxml2argvdata/powernv9-root-port.xml create mode 100644 tests/qemuxml2xmloutdata/powernv8-basic.ppc64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/powernv8-root-port.ppc64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/powernv8-two-sockets.ppc64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/powernv9-root-port.ppc64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/powernv9-root-port.xml
