Subject: [Qemu-devel] [PATCH v5 0/6]  Add a valid_cpu_types property
Date: Thu, 1 Feb 2018 16:42:03 -0800	[thread overview]
Message-ID: <cover.1517532021.git.alistair.francis@xilinx.com> (raw)


There are numorous QEMU machines that only have a single or a handful of
valid CPU options. 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 models are: cortex-m3, cortex-m4

V5:
 - Use cpu_model instead of cpu_type
V4:
 - Rebase
 - Remove spaces
V3:
 - Make the varialbes static
V2:
 - Rebase
 - Reorder patches
 - Add a Raspberry Pi 2 CPU fix
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
