Intel Currently Has No Plans For A Turbo Boost Max 3.0 Linux Driver

Just found a nugget of news from an Intel representative in case you have been eyeing an Intel Broadwell-E processor: there are no driver plans for Linux for the new Turbo Boost Max 3.0 functionality.

Turbo Boost Max 3.0 is a feature to the Intel Broadwell-E CPUs launched at the end of May. Turbo Boost Max 3.0 is about boosting the frequency of a single CPU core when a single-threaded application is keeping the system occupied. TBM Tech 3.0 is in contrast to Turbo Boost 2.0 that boosts the frequency of all CPU cores when needed for short periods of time. But over the older Turbo Boost tech, TBM 3.0 can maintain its boost frequency for a longer duration.

While TBM 3.0 for now is found just on the new Broadwell-E CPUs but presumably will be rolled out to more Intel CPUs with either Kabylake or Cannonlake. But for Linux users, unfortunately, there is no TBM 3.0 support.

One of Intel's press representatives has confirmed that there are "no [Linux] drivers planned for the Turbo Boost Max 3.0 feature." With that said, no extra hardware samples either for running Linux tests on Phoronix. Hopefully a TBM 3.0 Linux driver will emerge prior to the feature appearing on more processors.
