Hi all

Would like to ask the experts here regarding the Symmetric
Multi-Processing mode (SMP) with Energy aware scheduler (EAS) support
on the big + little cores system.

Hardware system:
Big and little cores have almost the same ISA, but the big core has
some extension instructions that little core doesn't have.

With this hardware system, is it still possible to use SMP with EAS?
Any suggestions supporting this kind of hardware system in Linux?

Thanks in advance.

Regards
Ley Foon
