I decided to go the\nextra mile and implement CPU hotplug via \"device_add\", as well as\n\"query-hotpluggable-cpus\". So the last patches in this series differ\nto v1. I tried to stick as much as possible to x86.\n\nOn s390x, only complete cores can be plugged. Cores have to be plugged in\nthe right order (core-id 0, 1, 2 ...). CPU hot unplug is not supported\nby the architecture.\n\nIn addition, we now also print the CPU model list in sorted order and allow\nonly 1 CPU for TCG.\n\nv1 -> v2:\n- \"exec,dump,i386,ppc,s390x: don't include exec/cpu-all.h explicitly\"\n-- added a few instances I missed\n- \"s390x: get rid of s390-virtio.c\"\n-- move everything in the first shot and clean the \"cpu_states\" stuff up\n in later patches, when we have ms->possible_cpus.\n- Added \"target/s390x: move typedef of S390CPU to its definition\"\n- Added \"s390x: move s390_virtio_hypercall() to s390-virtio-hcall.h\"\n- Added \"s390x: move two function declarations to s390-virtio-ccw.h\"\n- Added \"s390x: move sclp_service_call() to interrupt.c\"\n- \"target/s390x: use program_interrupt() in per_check_exception()\"\n-- Add a comment describing my concern\n- \"s390x: allow only 1 CPU with TCG\"\n-- Add a #define to easily be able to change it (e.g. for development)\n- Added \"target/s390x: set cpu->id for linux user when realizing\"\n- \"target/s390x: use \"core-id\" for cpu number/address/id handling\"\n-- I now use \"core-id\" as property name, because that will be used by\n device_add\n- \"target/s390x: rename next_cpu_id to next_core_id\"\n-- Also change to the term \"core_id\"\n- Added \"s390x: print CPU definitions in sorted order\"\n- Added \"s390x: allow cpu hotplug via device_add\"\n- Added \"s390x: CPU hot unplug via device_del cannot work\"\n- Added \"s390x: implement query-hotpluggable-cpu\"\n- Added \"s390x: get rid of cpu_s390x_create()\"\n\nDavid Hildenbrand (19):\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 target/s390x: move typedef of S390CPU to its definition\n s390x: move s390_virtio_hypercall() to s390-virtio-hcall.h\n s390x: move two function declarations to s390-virtio-ccw.h\n s390x: move sclp_service_call() to interrupt.c\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\n s390x: implement query-hotpluggable-cpus\n s390x: get rid of cpu_s390x_create()\n\n dump.c | 1 -\n exec.c | 2 -\n hw/s390x/Makefile.objs | 1 -\n hw/s390x/s390-virtio-ccw.c | 259 +++++++++++++++++++++++++++++++++++--\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 | 51 +-------\n include/hw/s390x/s390-virtio-ccw.h | 3 +\n include/hw/s390x/sclp.h | 1 +\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 | 4 +-\n target/s390x/cpu.c | 86 ++++--------\n target/s390x/cpu.h | 19 +--\n target/s390x/cpu_models.c | 65 ++++++----\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/interrupt.c | 52 ++++++++\n target/s390x/kvm.c | 3 +-\n target/s390x/misc_helper.c | 22 ++--\n target/s390x/translate.c | 5 +-\n 30 files changed, 443 insertions(+), 307 deletions(-)\n create mode 100644 hw/s390x/s390-virtio-hcall.h\n delete mode 100644 hw/s390x/s390-virtio.h"}
