描述

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.

研究方向
Focus on the mkerrors.sh file in the golang/sys repository. Modify the regex on line 583 (currently 'PRIO (PROCESS|PGRP|USER)') to include 'PRIO DARWIN THREAD', 'PRIO DARWIN PROCESS', 'PRIO DARWIN BG', and 'PRIO DARWIN NONUI'. After editing, run the script to regenerate the constants. Then create a pull request with the changes. Refer to the linked CPython issue for additional context on the Darwin efficiency core scheduling constants.
