It's like the early 90s again, but for modern Linux machines.
In the dawn of the Personal Computer revolution, programs were written with the clock speed in mind. As processors got faster, these programs didn't function the same. The solution was the "turbo" button, which ironically, was often wired such that when the button was pressed, the CPU ran slower.
Modern CPUs have performance scaling for different situations. Typically, this is probably something like "performance" or "powersave." In some ways, "performance" is "turbo" mode. So, that's what this is. A turbo button. For Linux.
This button doesn't attempt to work for all CPUs and all configurations.
It literally just writes the values "performance" or "powersave" to
/sys/devices/system/cpu/cpuN/cpufreq/scaling_governor and fails otherwise.
If you're system doesn't support this on Linux, then, well, submit a PR,
I guess?
