Re: [PATCH v2 0/8] Support Intel® Turbo Boost Max Technology 3.0

Hi!
- Feature is enabled by default for single socket systems

With Intel® Turbo Boost Max Technology 3.0 (ITMT), single-threaded performance is
optimized by identifying processor's fastest core and running critical workloads
on it.
Refere to:
http://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-max-technology.html
That does not really explain much.

How does it work? Do the different cores have different max
frequencies due to manufacturing differences? Ot is it running the
workload on coldest core?

Thanks,
								Pavel
