This series is based on the previous patchset from Chen Fan: https://lists.nongnu.org/archive/html/qemu-devel/2014-05/msg02360.html
We try to make cpu hotplug with device_add, and make "-device foo-x86_64-cpu" available, also we can set apic-id property with command line, if without setting apic-id property, we offer the first unoccupied apic id as the default new apic id. When hotplug cpu with device_add, additional check of APIC ID will be done after cpu object initialization which was different from 'cpu_add' command that check 'ids' at the beginning. The is the first half of the previous series: [RFC V2 00/10] cpu: add device_add foo-x86_64-cpu and i386 cpu hot remove support https://lists.nongnu.org/archive/html/qemu-devel/2014-08/msg04779.html --- Changelog since v3: -fix cross version migration issue -drop ICC bus impl -do a generic for apic to send gpe event -do not use migration code for CONFIG_USER_ONLY target Changelog since v2: -rebase on latest upstream. -add cpu instance finalize. Changelog since v1: -rebased on latest upstream. -introduce a help function to hide the access to icc_bus. -use a macro ACPI_ID_NOT_SET to replace the magic number(0xFFFFFFFF). Changelog since RFC: -split out APIC vmstate/QMP-monitor changes into separate patches. -add the handle of the startup cpus(-device foo). -remove duplicated checking about env->cpuid_apic_id. -do actual APIC ID allocation at realize time if it is not set before. -remove the unneeded x86_cpu_cpudef_instance_init(). -split off device_del support out here. --- Chen Fan (4): cpu/apic: drop icc bus/bridge/ icc_bus: remove icc related files cpu: introduce CpuTopoInfo structure for argument simplification cpu: add device_add foo-x86_64-cpu support Gu Zheng (4): qom/cpu: move register_vmstate to common CPUClass.realizefn qom/cpu: move apic vmstate register into x86_cpu_apic_realize monitor: use cc->get_arch_id as the cpu index i386/cpu: add instance finalize callback Zhu Guihua (2): cpu: introduce get_compat_arch_id() method and override it for X86CPU acpi: introduce acpi_send_gpe_event() MAINTAINERS | 6 -- cpus.c | 4 +- default-configs/i386-softmmu.mak | 1 - default-configs/x86_64-softmmu.mak | 1 - exec.c | 25 +++++--- hw/acpi/core.c | 7 +++ hw/acpi/cpu_hotplug.c | 6 +- hw/cpu/Makefile.objs | 2 - hw/cpu/icc_bus.c | 118 ------------------------------------- hw/i386/kvm/apic.c | 10 +++- hw/i386/pc.c | 27 ++------- hw/i386/pc_piix.c | 9 +-- hw/i386/pc_q35.c | 9 +-- hw/intc/apic.c | 16 +++-- hw/intc/apic_common.c | 17 +++--- include/hw/acpi/acpi.h | 3 + include/hw/cpu/icc_bus.h | 82 -------------------------- include/hw/i386/apic_internal.h | 9 +-- include/hw/i386/pc.h | 3 +- include/qom/cpu.h | 6 ++ monitor.c | 4 +- qom/cpu.c | 10 ++++ target-i386/cpu.c | 95 ++++++++++++++++++++++------- target-i386/cpu.h | 3 +- target-i386/topology.h | 66 ++++++++++++++++----- 25 files changed, 223 insertions(+), 316 deletions(-) delete mode 100644 hw/cpu/icc_bus.c delete mode 100644 include/hw/cpu/icc_bus.h -- 1.9.3
