On which object? There's no single object inside a machine model. Of course
you can expose MP IDs of CPU objects as properties and set them, but isn't it

It was a #define in v3, but i decided to change this in order to allow

In order to support up to 128 cores with GIC-500 (GICv3 implementation)
affinity1 must be used. GIC-500 support up to 32 clusters with up to
8 cores in a cluster. So for example, if one wishes to have 16 cores,
the options are: 2 clusters of 8 cores each, 4 clusters with 4 cores each.
It is possibl
