IIRC there are sysctls that list the number of cores of each type, and their cache sizes. So an application can check how many P cores there are, and choose to only spawn that many threads.

Yeah but it just means that software needs to tweak some parameters on M3 to slow spilling to E cores. In fact, a good system would always spill to E cores ands just let completion rates drive acceptance of work stealing.
