which just shows the scheduler is wrong. which people who cared to put the effort in already did manually with lasso. the only missing piece is random main kernel threads jumping on to p cores. AMD scheduler isn't perfect either. And both companies are going big/little. so plenty of room to keep improving.
correction: it shows that Intel Thread Director is wrong, and that the scheduler shouldn't trust it.
Thread Director doesn't do any directing, it's a a set of new registers the OS scheduler is supposed to read for feedback on how well a thread is running on a core. If APO can do it right, it means the scheduler is wrong.
facepalm are you daft?
how the scheduler gets information from ITD doesn't change what ITD does.
