Auto-CPUFreq 3.0 released this weekend as the newest version of this Linux user-space tool to help you extend your laptop battery life by automatically applying CPU speed and power optimizations. When all goes according to plan, Auto-CPUFreq means extending your battery life without compromises to the user experience.

One of the new features of Auto-CPUFreq 3.0 include the ability to override the CPU turbo setting (where available) via the program's command line interface or GUI. For those using the auto-cpufreq CLI, the new --turbo flag allows overriding the CPU turbo mode for this additional knob for either extending your battery life or still wanting to reach your CPU's peak clock speeds.

Any comments on why a user space tool is required for something that seems like it would be good to have in kernel?

For stability and security reasons, everything that can be done in user space instead of kernel space should be done in user space. Performance of this functionality is not critical.
