[v2,0/8] machine: Unified CPU type check

Message

Gavin Shan July 26, 2023, 12:31 a.m. UTC

There are two places where the user specified CPU type is checked to see
if it's supported or allowed by the board: machine_run_board_init() and
mc->init(). We don't have to maintain two duplicate sets of logic. This
series intends to move the check to machine_run_board_init().

PATCH[1-3] Improves the check in machine_run_board_init()
PATCH[4-8] Move the check mc->init() to machine_run_board_init()

v1: https://lists.nongnu.org/archive/html/qemu-arm/2023-07/msg00302.html

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 models are: cortex-a7, cortex-a15, cortex-a35, cortex-a55,
                        cortex-a72, cortex-a76, a64fx, neoverse-n1,
                        neoverse-v1, cortex-a53, cortex-a57, max

Changelog
=========
v2:
  * Constify mc->valid_cpu_types                                (Richard)
  * Print the supported CPU models, instead of typenames        (Peter)
  * Misc improvements for the hleper to do the check            (Igor)
  * More patches to move the check                              (Marcin)
