Hi, The patches doesn't apply on master anymore due to new capabilities being added in mainline, so I've rebased the patches with latest master here in case someone wants to test them: https://gitlab.com/danielhb/libvirt/-/tree/pnv_v2 Thanks, Daniel On 1/25/22 17:48, Daniel Henrique Barboza wrote:
Hi, This v2 has changes proposed by Peter and Daniel on the v1 review. Peter's reviewed-by tags were kept when applicable. The usability change made is that, now, we'll fail to launch powernv domains that has a pnv-phb* device and it's running a QEMU version that doesn't support these devices to be user creatable. Trying to run the 'powernv8-basic' domain with a QEMU 6.2.0 binary will result in an error: $ sudo ./run tools/virsh define ../tests/qemuxml2argvdata/powernv8-basic.xml error: Failed to define domain from ../tests/qemuxml2argvdata/powernv8-basic.xml error: unsupported configuration: The 'pnv-phb3' device is not supported by this QEMU binary Using the current QEMU upstream will allow the domain to be defined and started. Changes from v1: - all tests are now using CAPS_LATEST; - QEMU_CAPS_DEVICE_PNV_PHB3_ROOT_PORT is no longer being used. Capability for the pnv-phb3-root-port is infered to exist if the capabilitity for its PHB (QEMU_CAPS_DEVICE_PNV_PHB3) is present. Same thing for the case of QEMU_CAPS_DEVICE_PNV_PHB4_ROOT_PORT and QEMU_CAPS_DEVICE_PNV_PHB4; - QEMU_CAPS_DEVICE_PNV_PHB3 and QEMU_CAPS_DEVICE_PNV_PHB4 are no longer being probed. They are being set by hand after checking for QEMU version in virQEMUCapsInitQMPVersionCaps(); - patch 01 (QEMU ppc64 capabilities for qemu 7.0): * dropped since it's already upstream - patch 09 (forbid powernv domains migration): * removed. This will be handled on QEMU side - patch 14 (new): * added documentation of the different semantics 'targetIndex' will have for PowerNV PHBs - several other minor changes suggested by Peter - v1 link: https://listman.redhat.com/archives/libvir-list/2022-January/msg00902.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 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: format pnv-phb3-root-port empty addr 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 | 157 ++++++++++++++---- src/conf/domain_conf.h | 8 + src/conf/domain_validate.c | 5 +- src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 28 +++- src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_command.c | 21 ++- src/qemu/qemu_domain.c | 56 ++++++- src/qemu/qemu_domain.h | 4 +- src/qemu/qemu_domain_address.c | 64 ++++++- src/qemu/qemu_validate.c | 62 ++++++- .../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 + 34 files changed, 855 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
