Assuming the lwn article is accurate:
Hmm. So we have hw capable of running 8 cores, and then we introduce strange
switching code, because "scheduler is not ready". Sounds like a bad idea.
I'd say:
* expose all 8 cores.
* as long as scheduler is not ready, you can offline "the other" set of cores...
/sys/.../cpu/..../online
That way, I suspect scheduler will be fixed rather quickly.
