I decided to go the\nextra mile and implement CPU hotplug via \"device_add\", as well as\n\"query-hotpluggable-cpus\".\n\nOn s390x, only complete cores can be plugged. CPU hot unplug is currently\nnot supported by the architecture.\n\nSupport for hotplugging CPUs in random core-id order (last two patches)\nis added. We once hat a KVM bug preventing this, but the stable patch\nshould now be included in relevant places - 152e9f65d66f (\"KVM: s390: fix\nwrong lookup of VCPUs by array index\"). Current tooling will plug them in\nsequential order anyway, so it should not hurt.\n\n\nv3 -> v4:\n* Dropped \"target/s390x: move typedef of S390CPU to its definition\"\n* Added \"target/s390x: move some s390x typedefs to cpu-qom.h\"\n - this moves some typedefs and makes cpu-qom.h independent from\n cpu_models.h. This is necessary to cleanly use cpu-qom.h in sclp.c\n later.\n* \"s390x: move sclp_service_call() to sclp.h\"\n - Use cpu-qom.h now as a s390x replacement for typedefs.h\n* \"target/s390x: use \"core-id\" for cpu number/address/id handling\"\n - Indicate also in error messages the property name \"core-id\". So just\n the error messages were touched.\n\n\nDavid Hildenbrand (21):\n exec,dump,i386,ppc,s390x: don't include exec/cpu-all.h explicitly\n cpu: drop old comments describing members\n s390x: get rid of s390-virtio.c\n s390x: rename s390-virtio.h to s390-virtio-hcall.h\n s390x: move s390_virtio_hypercall() to s390-virtio-hcall.h\n s390x: move subsystem_reset() to s390-virtio-ccw.h\n target/s390x: move some s390x typedefs to cpu-qom.h\n s390x: move sclp_service_call() to sclp.h\n target/s390x: use trigger_pgm_exception() in\n s390_cpu_handle_mmu_fault()\n target/s390x: use program_interrupt() in per_check_exception()\n s390x: allow only 1 CPU with TCG\n target/s390x: set cpu->id for linux user when realizing\n target/s390x: use \"core-id\" for cpu number/address/id handling\n target/s390x: rename next_cpu_id to next_core_id\n s390x: print CPU definitions in sorted order\n s390x: allow cpu hotplug via device_add\n s390x: CPU hot unplug via device_del cannot work for now\n s390x: implement query-hotpluggable-cpus\n s390x: get rid of cpu_s390x_create()\n s390x: generate sclp cpu information from possible_cpus\n s390x: allow CPU hotplug in random core-id order\n\n dump.c | 1 -\n exec.c | 1 -\n hw/s390x/Makefile.objs | 1 -\n hw/s390x/s390-virtio-ccw.c | 245 +++++++++++++++++++++++++++++++++++--\n hw/s390x/s390-virtio-hcall.c | 2 +-\n hw/s390x/s390-virtio-hcall.h | 21 ++++\n hw/s390x/s390-virtio.c | 37 ------\n hw/s390x/s390-virtio.h | 35 ------\n hw/s390x/sclp.c | 34 +++--\n include/hw/s390x/s390-virtio-ccw.h | 2 +\n include/hw/s390x/sclp.h | 2 +\n include/qom/cpu.h | 6 +-\n qapi-schema.json | 16 +++\n target/i386/arch_dump.c | 1 -\n target/i386/arch_memory_mapping.c | 1 -\n target/i386/svm_helper.c | 1 -\n target/ppc/arch_dump.c | 1 -\n target/s390x/arch_dump.c | 1 -\n target/s390x/cpu-qom.h | 7 +-\n target/s390x/cpu.c | 102 ++++++---------\n target/s390x/cpu.h | 18 +--\n target/s390x/cpu_models.c | 58 ++++++---\n target/s390x/cpu_models.h | 8 +-\n target/s390x/diag.c | 1 +\n target/s390x/excp_helper.c | 5 +-\n target/s390x/helper.c | 47 +------\n target/s390x/internal.h | 1 -\n target/s390x/kvm.c | 1 +\n target/s390x/misc_helper.c | 21 ++--\n target/s390x/translate.c | 5 +-\n 30 files changed, 410 insertions(+), 272 deletions(-)\n create mode 100644 hw/s390x/s390-virtio-hcall.h\n delete mode 100644 hw/s390x/s390-virtio.h"}
