Corefreq: How to specify output in OS definition

Corefreq: How to specify output in OS definition

[phodina via]

Hi Tobias,

how do you specify output "linux-module" for the package corefreq in the OS definition in the field kernel-loadable-modules?

Hi Petr,

I think this package might predate k-l-m, in which case the honest answer is ‘I don't’ :-)  If it's not supported, however, it should be.

I'll try to remember to check how I use it when I get back to my laptop.  If I forget, complain.

Kind regards,

T G-R

Sent on the go.  Excuse or enjoy my brevity.

I was able to get it to say it would be added when I added the following
to my OS config:

(kernel-loadable-modules (list `(,corefreq "linux-module")))

I didn't actually try building or running it though.

Adding this line to OS definition fixes the initial issue.

However, you still need to manually add the kernel module and start the corefreqd daemon as a root.

```
$ corefreq-cli
Daemon connection error code 2
corefreq-ro-shm: 'No such file or directory' @ line 19075
$ corefreqd
corefreqd execution error code 13
Permission denied @ line 8002
$ sudo -E corefreqd
Password:
Driver connection error code 2
/dev/corefreqk: 'No such file or directory' @ line 7998
$ sudo -E modprobe corefreqk
$ sudo -E corefreqd &
CoreFreq Daemon 1.90.1  Copyright (C) 2015-2022 CYRIL INGENIERIE
$ corefreq-cli
# Now it launches :-)
```
So maybe a service would be handy, what do you think?

Sounds like you have your work cut out for you :)
