Also note that CPU 0, (the boot cpu and usually a 'P' core), is always enabled regardless of this setting. So you can't create an L core only configuration by setting hw.blockcpu=EPS. (Which might plausibly have some uses in very low power consumption applications.) If you do set hw.blockcpu=EPS, then processing power won't be deterministic as processes will often migrate to cpu 0, (the only P core left enabled).
