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] 4. Helper functions to support unrealization of CPU objects [Patch 8,9] 5. Misc [Patch 2,3,10] Repository: [*] https://github.com/salil-mehta/qemu.git virt-cpuhp-armv8/rfc-v2.common.v3 Revision History: RFC V2 -> RFC V3 1. Addressed Jonathan Cameron's comments - Fixed 'vcpu-id' type wrongly changed from 'unsigned long' to 'integer' - Removed unnecessary use of variable 'vcpu_id' in kvm_park_vcpu - Updated [Patch V2 03/10] commit-log with details of ACPI_CPU_SCAN_METHOD macro - Updated [Patch V2 05/10] commit-log with conditional event handler method details - Added Reviewed-by tags for patches {2,3,4,6,7} 2. Addressed Gavin Shan's comments - Remove unnecessary use of variable 'vcpu_id' in kvm_par_vcpu - Fixed return value in kvm_get_vcpu from -1 to -ENOENT - Reset the value of 'gdb_num_g_regs' in gdb_unregister_coprocessor_all - Fixed the kvm_{create,park}_vcpu prototypes docs - Added Reviewed-by tags for patches {2,3,4,5,6,7,9,10} 3. Addressed one earlier missed comment by Alex Bennée in RFC V1 - Added traces instead of DPRINTF in the newly added and some existing functions RFC V1 -> RFC V2 1. Addressed Alex Bennée's comments - Refactored the kvm_create_vcpu logic to get rid of goto - Added the docs for kvm_{create,park}_vcpu prototypes - Splitted the gdbstub and AddressSpace destruction change into separate patches - Added Reviewed-by tags for patches {2,10} 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 | 64 ++++++++++++++++++++------ accel/kvm/trace-events | 4 ++ gdbstub/gdbstub.c | 15 ++++++ hw/acpi/acpi-cpu-hotplug-stub.c | 6 +++ hw/acpi/cpu.c | 27 +++++++---- 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 +++- 16 files changed, 187 insertions(+), 28 deletions(-) -- 2.34.1
