#205333 — powernow-k8 module missing in kernel 4.9.0-8-rt-amd64

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

this command

$ grep -i powernow /boot/con*

should inform you: maybe instead of "m" for module, the result would be
"y" for included in the kernel (I do not know)

It's included as a module in *my* kernel 4.9.0-8-amd64:

curty@einstein:~$  grep -i powernow /boot/con*
/boot/config-4.9.0-7-amd64:CONFIG_X86_POWERNOW_K8=m
/boot/config-4.9.0-8-amd64:CONFIG_X86_POWERNOW_K8=m

I have verified: CONFIG_X86_POWERNOW_K8 is not mentionned in the config
file of linux-image-4.9.0-8-rt-amd64.
I do not know if it is a bug. But considering a real-time kernel, maybe
the Powernow functionnalities (frequency scaling and power management)
are partly or totally irrelevant?

The OP said she had an rt kernel? I missed that detail.

After you said that, I did, too (miss that part). For fun, I read back
through the included snippets still in my active inbox and, nope,
didn't see it...

So I searched my email trash bucket...

Never got past the subject line at that point. That would be the same
subject line that still sits in the active inbox, too. I'm thinking...
surely fodder for a cognitive/comprehension study somewhere.

In Reality, it's about how I personally mass-read emails. Right-click,
pop a whole bunch open in separate tabs, rapid read, and delete. That
reminds me, there's another possibly still unanswered Debian-User
thread that I keep meaning to go back to and pose a possible answer.
My method of email reading annoyingly, apparently, repeatedly triggers
a duplication of that other User's issue.

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.
