Yes, my HW support it (I have already used it for keeping a VM on specified CPU core), but it doesn't solve the "generic ratio problem". For this case it can be usable - ratio 3:1 on 4-core CPU is simple task with numactl, I agree, but I'm looking for some more generic solution where you can make different ratios, which is not possible to do with numactl (for instance 4:1 on 4 cores).
