Better Turbo Boost Max 3.0 Support Is Landing For Linux 4.11

Better support for Intel Turbo Boost Max 3.0 are among the changes to find with the platform-drivers-x86 updates for the Linux 4.11 kernel.

With Linux 4.10 came initial Turbo Boost Max 3.0 (TBM3) support, but it was only enabled for systems with the motherboard/BIOS exposing hardware P-States. For many Broadwell-E boards, including mine, this wasn't the case and as such TBM 3.0 isn't currently working on systems like my Core i7 6800K. But Intel developers have been working on expanded Turbo Boost Max 3.0 support for non-HWP systems and that code is now set to land for Linux 4.11.

The platform-drivers-x86 update is bringing the intel_turbo_max_3 driver that will provide the maximum core frequency information to the scheduler. Turbo Boost Max 3.0 delivers 15% better single-threaded performance, according to Intel's marketing on Windows, and this form of Turbo Boost is about boosting the performance for single-threaded workloads by moving them to the fastest core at a higher frequency than the rest.

Other changes for platform-drivers-x86 include adding the Dell Latitude 74890 to the dell-laptop driver whitelist, the intel-hid code now supports a five button array, many updates to the intel_mid_powerbtn driver, support for the HP ZBook 17 in the hp_accel driver, and a variety of other updates.
