To simplyfy the management of specificying which CPU is/isn't valid let's create a property that can be set in the machine init. We can then check to see if the user supplied CPU is in that list or not. I have added the valid_cpu_types for some ARM machines only at the moment. Here is what specifying the CPUs looks like now: $ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf -nographic -cpu "cortex-m3" -S QEMU 2.10.50 monitor - type 'help' for more information (qemu) info cpus * CPU #0: thread_id=24175 (qemu) q $ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf -nographic -cpu "cortex-m4" -S QEMU 2.10.50 monitor - type 'help' for more information (qemu) q $ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf -nographic -cpu "cortex-m5" -S qemu-system-aarch64: unable to find CPU model 'cortex-m5' $ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf -nographic -cpu "cortex-a9" -S qemu-system-aarch64: Invalid CPU type: cortex-a9-arm-cpu The valid types are: cortex-m3-arm-cpu, cortex-m4-arm-cpu V1: - Small fixes to prepare a series instead of RFC - Add commit messages for the commits - Expand the machine support to ARM machines RFC v2: - Rebase on Igor's work - Use more QEMUisms inside the code - List the supported machines in a NULL terminated array Alistair Francis (5): machine: Add a valid_cpu_types property netduino2: Specify the valid CPUs xlnx-zcu102: Specify the valid CPUs xilinx_zynq: : Specify the valid CPUs raspi: : Specify the valid CPUs hw/arm/netduino2.c | 9 ++++++++- hw/arm/raspi.c | 6 ++++++ hw/arm/xilinx_zynq.c | 5 +++++ hw/arm/xlnx-zcu102.c | 10 ++++++++++ hw/arm/xlnx-zynqmp.c | 16 +++++++++------- hw/core/machine.c | 35 +++++++++++++++++++++++++++++++++++ include/hw/arm/xlnx-zynqmp.h | 1 + include/hw/boards.h | 1 + 8 files changed, 75 insertions(+), 8 deletions(-) -- 2.11.0
