For as long as I have known the kernels we use, they have used the userspace cpu governor as the default, which basically does nothing if there is no userspace software to handle the scaling. As far as I can tell, we don't seem to have any officially sanctioned userspace software to handle this task anymore in the main branch. I think KDE used to have something to do this, but not anymore. Is there any suitable substitute? If not, I would propose we switch the default cpu governor to conservative or ondemand so the kernel can do the scaling. From what I've read, ondemand is generally more responsive than conservative to cpu loads. But note, this won't enable cpu scaling automatically, as the modules must be explicitly loaded. udev doesn't support autoloading for them. It just reduces the steps needed to get it working by making the scaling work out of the box once the proper module is loaded. Thoughts?
