This series intends to use the generic CPU type invalidation on the hw/arm/virt machines. PATCH[1] factors the CPU type invalidation logic in machine_run_board_init() to a helper validate_cpu_type(). PATCH[2] uses the generic CPU type invalidation for hw/arm/virt machines PATCH[3] support "host-arm-cpu" CPU type only when KVM or HVF is visible Testing ======= With the following command lines, the output messages are varied before and after the series is applied. /home/gshan/sandbox/src/qemu/main/build/qemu-system-aarch64 \ -accel tcg -machine virt,gic-version=3,nvdimm=on \ -cpu cortex-a8 -smp maxcpus=2,cpus=1 \ : Before the series is applied: qemu-system-aarch64: mach-virt: CPU type cortex-a8-arm-cpu not supported After the series is applied: qemu-system-aarch64: Invalid CPU type: cortex-a8-arm-cpu The valid types are: cortex-a7-arm-cpu, cortex-a15-arm-cpu, \ cortex-a35-arm-cpu, cortex-a55-arm-cpu, cortex-a72-arm-cpu, \ cortex-a76-arm-cpu, a64fx-arm-cpu, neoverse-n1-arm-cpu, \ neoverse-v1-arm-cpu, cortex-a53-arm-cpu, cortex-a57-arm-cpu, \ max-arm-cpu Gavin Shan (3): machine: Factor CPU type invalidation out into helper hw/arm/virt: Use generic CPU type invalidation hw/arm/virt: Support host CPU type only when KVM or HVF is configured hw/arm/virt.c | 23 +++----------- hw/core/machine.c | 81 +++++++++++++++++++++++++---------------------- 2 files changed, 48 insertions(+), 56 deletions(-)
