Add architecture agnostic code to support vCPU Hotplug
|
expand
|
Virtual CPU hotplug support is being added across various architectures [1][3]. This series adds various code bits common across all architectures: 1. vCPU creation and Parking code refactor [Patch 1] 2. Update ACPI GED framework to support vCPU Hotplug [Patch 4,6,7] 3. ACPI CPUs AML code change [Patch 5] 3. Helper functions to support unrealization of CPU objects [Patch 8,9] 4. Misc [Patch 2,3,10] References: [1] https://lore.kernel.org/qemu-devel/20230926100436.28284-1-salil.mehta@huawei.com/ [2] https://lore.kernel.org/all/20230913163823.7880-1-james.morse@arm.com/ [3] https://lore.kernel.org/qemu-devel/cover.1695697701.git.lixianglai@loongson.cn/ Jean-Philippe Brucker (1): target/arm/kvm: Write CPU state back to KVM on reset Salil Mehta (9): accel/kvm: Extract common KVM vCPU {creation,parking} code hw/acpi: Move CPU ctrl-dev MMIO region len macro to common header file hw/acpi: Add ACPI CPU hotplug init stub hw/acpi: Init GED framework with cpu hotplug events hw/acpi: Update CPUs AML with cpu-(ctrl)dev change hw/acpi: Update GED _EVT method AML with cpu scan hw/acpi: Update ACPI GED framework to support vCPU Hotplug physmem: Add helper function to destroy CPU AddressSpace gdbstub: Add helper function to unregister GDB register space accel/kvm/kvm-all.c | 63 +++++++++++++++++++------- gdbstub/gdbstub.c | 14 ++++++ hw/acpi/acpi-cpu-hotplug-stub.c | 6 +++ hw/acpi/cpu.c | 25 ++++++---- hw/acpi/generic_event_device.c | 22 +++++++++ hw/i386/acpi-build.c | 2 +- include/exec/cpu-common.h | 8 ++++ include/exec/gdbstub.h | 5 ++ include/hw/acpi/cpu.h | 5 +- include/hw/acpi/cpu_hotplug.h | 4 ++ include/hw/acpi/generic_event_device.h | 5 ++ include/hw/core/cpu.h | 1 + include/sysemu/kvm.h | 14 ++++++ softmmu/physmem.c | 25 ++++++++++ target/arm/kvm.c | 8 +++- 15 files changed, 179 insertions(+), 28 deletions(-)
