Heh. It's the same on every Linux forum I've ever visited/joined up with. It's always the 'Beginners/Noobs' sections where you find the most ridiculously technical - and often, utterly pointless - questions being asked....
@beann :- Just out of curiosity, why would you NEED to be able to change your CPU frequency on a second by second basis? I fail to see what possible use it could have.
If you want to be able to view your CPU frequency literally by-the-second, install the
gKrellM system monitor. And then, install the
gkx86info plugin. And what you get is this:-
Below the legend for the top CPU graph (you can have one for every core if you want, but it uses a lot of screen real-estate if you've got a lot of cores; me, I prefer a single composite graph) you will see the gkx86info plugin in action.......displaying the CPU frequency second-by-second.
I
do like my toys!
Works for me. There's quite probably CLI solutions that will do the same thing, although gKrellM is not exactly resource-heavy.....quite the opposite, in fact.

Kernel compilation is not the easy process you might imagine it to be. This page from the Arch Linux wiki - one of the best sources of information anywhere in the open-source world - may give you some pointers. Do bear in mind, however, that these commands are specific to Arch Linux.......though it'll be easy enough to modify them for most mainstream distros.
