Phoronix: Expanded Turbo Boost Max 3.0 Support Is Being Worked On For Linux

With the forthcoming Linux 4.10 kernel there is finally support for Turbo Boost Max 3.0 as featured in some newer Intel CPUs. But, unfortunately, the code in Linux 4.10 doesn't work for all TBM3-capable systems out there, but a new kernel patch is being worked on for Linux 4.11 or later to make it work with more hardware...

The patch can be found here. Hopefully we'll see it land for Linux 3.11 so more Turbo Boost Max 3.0 capable systems (...)

There are a lot of systems out there that don't support HWP. We have issued another patch to enable TBM3 for those systems that don't: https://lkml.org/lkml/2017/1/18/812

For those systems that don't support HWP, we have another patch to enable TBM 3.0 for them: https://lkml.org/lkml/2017/1/18/812. Hopefully that will land in 4.11 kernel.

"TBM3-capable systems", I guess that means motherboards?
How can I find out if my motherboard ASRock Fatal1ty X99X Killer running i7-6850K are TBM3-capable?
