对于Mac和BSD，我如何找到当前线程运行的cpu？

[英]How do I find the cpu the current thread is running on, for Mac and BSD?

I'm looking for a function on Mac OS and BSD that's equivalent to Linux's sched_getcpu() , and Windows' GetCurrentProcessorNumberEx() in order to implement a library for cpu-local storage. 我正在寻找Mac OS和BSD上的一个功能，它相当于Linux的sched_getcpu()和Windows的GetCurrentProcessorNumberEx() ，以便为cpu本地存储实现一个库。 It's clearly possible to emulate this with the cpuid or rdtscp instructions, but it's possible to do better with kernel cooperation: https://lkml.org/lkml/2007/1/6/190 . 显然可以使用cpuid或rdtscp指令来模拟它，但是可以通过内核协作做得更好： https ：//lkml.org/lkml/2007/1/6/190。

I already know that the thread's current CPU may change by the time I use the information. 我已经知道线程的当前CPU可能会在我使用信息时发生变化。

There are one or two questions which cover queue tracking for OSX, as well as a dispatch_get_global_queue wiki page which covers the equivalent for BSD. 有一个或两个问题涵盖了OSX的队列跟踪，以及一个dispatch_get_global_queue wiki页面，它涵盖了BSD的等价物。 I don't know if you can map a queue to a CPU, but if so, that would seem to be the closest equivalent. 我不知道你是否可以将队列映射到CPU，但如果是这样，那似乎是最接近的等价物。
