[PATCH 0/5] hw/cpu/cluster: Restrict CPU cluster to a particular CPU type

Posted by Philippe Mathieu-Daudé 1 year, 2 months ago

Following Alex's comment [1] on "Introduce hybrid CPU topology"
RFC [2], this series strengthen a bit the CPU cluster by
restricting it to a particular CPU type.

We'd rather have a single way of creating heterogeneous (hybrid)
CPU topology. Note the CPU cluster is not user-creatable, so few
more work is required in this area.

Based-on: <20230216122524.67212-1-philmd@linaro.org>
  [3] "Have object_child_foreach() take Error* and return boolean"
