Rob,
Indeed my colleague pointed that out to me as well. In the meantime, what's the best way to test the MPAM feature (8.4 optional)?

I don't think you can mount resctrl without MPAM h/w support.

Does an Apple M1 have MPAM?

Doesn't really matter because MPAM within a VM is not supported in the snapshot.
