Enable CONFIG_UCLAMP_TASK by default in debian

[Qais Yousef]

Hi

Debian kernels don't ship with CONFIG_UCLAMP_TASK and CONFIG_UCLAMP_TASK_GROUP
configs enabled in the kernel, is there any reason for that?

These configs enable smarter performance management for tasks and it'd be good
to know if there's a reason preventing you from enabling it.

Some useful docs:

https://kernel.org/doc/html/latest/scheduler/sched-util-clamp.html?highlight=util+clamp
https://man7.org/linux/man-pages/man1/uclampset.1.html

Happy to contribute patches if that helps.


Thanks

Hi

I cannot yet judge if it is sensible, as unkown which impact it
otherwise has to enable those, but let's make a tracking bug for your
request.

Sorry for the delayed response.

When uclamp is not used, it's protected with a static key in the kernel, so
should add no extra overhead when not used; if that's the concern you have.

Ubuntu ships with these configs enabled FWIW.

Thanks for creating the bug!
