説明
Proposal Details
Darwin has the ability to force scheduling to the efficiency cores on Apple Silicon through the setpriority syscall, but the integer constants currently aren't exposed.
I think changing the regex here: cs.opensource.google / github from PRIO_(PROCESS|PGRP|USER) to PRIO_(PROCESS|PGRP|USER|DARWIN_THREAD|DARWIN_PROCESS|DARWIN_BG|DARWIN_NONUI) or PRIO_(PROCESS|PGRP|USER|DARWIN_(THREAD|PROCESS|BG|NONUI)) would result in being able to force execution onto an efficiency core.
As an additional reference, here's the CPython PR: https://github.com/python/cpython/issues/103545
I'd love to actually land this change in Go myself, but frankly don't know where to begin.
