I now note the 'rt' in the subject line, which incited me to read the
body of the OP's article with greater care.

 Hello, I was trying to activate the module powernow-k8 to put the
 system in "performance" and I realized that it is not there. In the
 kernel 4.9.0-8-amd64 if it appears and is fully functional. It has been
 deleted for something special, is it a bug? Cheers

Ignoring the 'if' in the second sentence (no doubt a typo), the OP seems
to be saying the powernow-k8 module appears in the 4.9.0-8-amd64 kernel,
whereas it's absent in the rt version of that kernel.

Didier must be right and cpu scaling and real time don't mix.
