Series allows to configure NUMA mapping at runtime using QMP/HMP interface. For that to happen it introduces a new '-paused' CLI option which allows to pause QEMU before machine_init() is run and adds new set-numa-node HMP/QMP commands which in conjuction with info hotpluggable-cpus/query-hotpluggable-cpus allow to configure NUMA mapping for cpus.
HMP configuration session for CLI '-smp 1,maxcpus=2' would look like: (qemu) info hotpluggable-cpus Hotpluggable CPUs: type: "qemu64-x86_64-cpu" vcpus_count: "1" CPUInstance Properties: socket-id: "1" core-id: "0" thread-id: "0" type: "qemu64-x86_64-cpu" vcpus_count: "1" qom_path: "/machine/unattached/device[0]" CPUInstance Properties: socket-id: "0" core-id: "0" thread-id: "0" (qemu) set-numa-node node,nodeid=0 (qemu) set-numa-node node,nodeid=1 (qemu) set-numa-node cpu,socket-id=0,node-id=0 (qemu) set-numa-node cpu,socket-id=1,node-id=1 (qemu) info hotpluggable-cpus Hotpluggable CPUs: type: "qemu64-x86_64-cpu" vcpus_count: "1" CPUInstance Properties: node-id: "1" socket-id: "1" core-id: "0" thread-id: "0" type: "qemu64-x86_64-cpu" vcpus_count: "1" CPUInstance Properties: node-id: "0" socket-id: "0" core-id: "0" thread-id: "0" (qemu) cont git tree for testing: https://github.com/imammedo/qemu qmp_preconfig_rfc CC: ebl...@redhat.com CC: arm...@redhat.com CC: ehabk...@redhat.com CC: pkre...@redhat.com CC: da...@gibson.dropbear.id.au CC: peter.mayd...@linaro.org CC: pbonz...@redhat.com CC: coh...@redhat.com Igor Mammedov (6): numa: postpone options post-processing till machine_run_board_init() numa: split out NumaOptions parsing into parse_NumaOptions() possible_cpus: add CPUArchId::type field CLI: add -paused option HMP: add set-numa-node command QMP: add set-numa-node command hmp.h | 1 + include/hw/boards.h | 2 ++ include/sysemu/numa.h | 2 ++ include/sysemu/sysemu.h | 1 + hmp-commands.hx | 13 ++++++++ hmp.c | 23 ++++++++++++++ hw/arm/virt.c | 3 +- hw/core/machine.c | 18 ++++++----- hw/i386/pc.c | 4 ++- hw/ppc/spapr.c | 13 +++++--- hw/s390x/s390-virtio-ccw.c | 1 + numa.c | 79 ++++++++++++++++++++++++++++++++++------------ qapi-schema.json | 13 ++++++++ qemu-options.hx | 15 +++++++++ qmp.c | 5 +++ vl.c | 54 ++++++++++++++++++++++++++++++- 16 files changed, 210 insertions(+), 37 deletions(-) -- 2.7.4
