Isn't this basically what MPIDR_EL1 is supposed to indicate?
We do not yet implement all of that in QEMU, but should.
QEMU has socket/cluster/core/thread model which could map to
aff3/aff2/aff1/aff0 (or aff0/1/2/3) of MPIDR_EL1 register, right? But it does
not.
Yes, I know, but there's patches on list that started to deal with MPIDR.SMT,
