Ananicy-cpp argument list too long

Issues & Assistance
1

Hi,

after installing ananicy-cpp from the performance part i saw that my log gets spammed with a lot of messages from ananicy-cpp:

the problem seems to be related to not being able to renice the applications due to invalid call to a kernel function:

|11-12-2022 16:08|ananicy-cpp|sched_setattr: Argument list too long|
|11-12-2022 16:08|ananicy-cpp|[2022-12-11 16:08:20.971] [error] set_latency_nice: Unknown error, errno is Argument list too long(7)|

strace feedback gave me the cause in the call sched_setattr

you see this pop up every time ananicy-cpp is trying to renice something. I tried with the git and the standard aur package

i tried with the current lts kernel (5.15.82-1-lts) and with the linux kernel (6.0.12-arch1-1) but the problem happened with both.

i disabled ananicy-cpp for now. I mostly wnat to check if anybody else has this problem.

my system info can be found here:

Hi!

Yes, I have this issue too.

And presently my picom is sucking quite a bit of CPU .. related?

By the way, I wanted to test it but I found out that on my computer ananicy-cpp hogs the CPU (100% on both cores, on and off every few seconds) and I gave up.
I think I've seen this issue reported somewhere in the past but did not find it again.

I can confirm this issue as well. The journald spam is more or less constant--mostly just variations of sched_setattr: Argument list too long over and over.

I read through the issue page here: Issues · Ananicy Cpp / Ananicy Cpp · GitLab and the AUR page for ananicy-cpp as well but there is no sign of anyone else having this issue. A Whoogle search for "ananicy-cpp" "argument list too long" turns up exactly one hit--this forum post. :smirk:

I started poking around a little bit in /etc/ananicy.d/, but there must be a thousand rules in there and the truth is I don't even really know what I am looking at.

I wonder if something is awry with the Garuda implementation? If not, we should open an issue on the Ananicy-cpp GitLab.
