We have 51 questions tagged . This seems like an extremely general, cross-cutting concept that isn't useful as a tag. However, most questions tagged are questions about CPU frequency. The tag has no tag wiki.

We also have a tag. Some questions currently have both tags. It seems to me that could (and thus far has been) used to cover the entire concept of CPU frequency, though in theory it is more specific than that. Its tag wiki excerpt currently says:

CPU Frequency, or CPU Frequency Scaling. This is implemented in the Linux kernel, and in versions since 3.4 use an ondemand governor by default, which saves power by using as much as is needed.

A couple questions are about CPU frequency but use the tag in a broader way, or are about something similar to but not the same as CPU frequency:

A significant minority of questions aren't about CPU frequency or anything related to it:

What should we do with the tag? Should we keep it? If so, should it retain is currently very general meaning? Should we remove it from questions that aren't about CPU frequency and make it a synonym of ? Or should we edit it out of the posts that currently have it, replacing it with or other tags where applicable?

My inclination is to think it's fine to on any post about CPU frequency, and that the tag need not exist. But I'm not sure.

  • I'd prefer all tags to be pretty general and using combinations of those to add specific meaning. For example, one could have both frequency and cpu if they mean CPU frequency. Or they could have ram overclock frequency for some another question. Aug 15, 2019 at 12:33

    I think that cpufreq is supposed to refer to frequency scaling and not just cpu frequency. kernel.org/doc/html/v4.14/admin-guide/pm/…
