-# the name.  However, if required, architectures can expose relevant

-# @CpuModelExpansionType:

-# An enumeration of CPU model expansion types.
-#
-# @static: Expand to a static CPU model, a combination of a static
-#     base model name and property delta changes.  As the static base
-#     model will never change, the expanded CPU model will be the
-#     same, independent of QEMU version, machine type, machine
-#     options, and accelerator options.  Therefore, the resulting
-#     model can be used by tooling without having to specify a
-#     compatibility machine - e.g. when displaying the "host" model.
-#     The @static CPU models are migration-safe.
-#
-# @full: Expand all properties.  The produced model is not guaranteed
-#     to be migration-safe, but allows tooling to get an insight and
-#     work with model details.
-#
-# .. note:: When a non-migration-safe CPU model is expanded in static
-#    mode, some features enabled by the CPU model may be omitted,
-#    because they can't be implemented by a static CPU model
-#    definition (e.g. cache info passthrough and PMU passthrough in
-#    x86).  If you need an accurate representation of the features
-#    enabled by a non-migration-safe CPU model, use @full.  If you
-#    need a static representation that will keep ABI compatibility
