Unified Linux CPU Boost Support Still Being Worked On

Linux Kernel

Kernel developers are still working on CPU Boost mode support for the Linux kernel's cpufreq to unify hardware and software-based solutions for CPU overclocking.

Samsung's Lukasz Majewski posted the ninth version of the CPUfreq Boost patches on Monday morning to unify hardware-based solutions like Intel's Turbo Frequency and AMD's Turbo Core with software-based solutions like the Samsung Exynos SoC Boost mode. With the patch series, it's the first time that software-managed overclocking has been added to Samsung Exynos ARM SoCs for running at higher than normal frequencies when the temperature is normal.

In unifying and cleaning-up this cpufreq code, there's now a unified /sys/devices/system/cpu/cpufreq/boost attribute for toggling CPU "boost" support on the different implementations. The Linux kernel's framework is also extended as part of the patches for disabling software boosting when hitting a thermal trip point.

For details on the CPUfreq core CPU Boost mode support see the new patch series and in particular patch 1 describes the changes to the cpufreq core for this boost frequency support.
