Afaik this was mostly for compiler people or other developers doing benchmarks to be able to avoid fluctating numbers caused by turbo/boost mode. I don't know whether it's used by any userspace tool. If, it would certainly be an AMD specific tool for developers. If you (AMD) know a userspace tool out there it may make sense to keep it the one or other kernel round, otherwise I guess it can simply be deleted. I will add the functionality (to enable/disable turbo/boost mode) to cpupower userspace tool as soon as this is in. Shouldn't be much more than a -t option and a one liner to read out or set another cpufreq sysfs file.
