How to enable PSR on Fedora 37

Hi everyone.

I’m trying to enable PSR for my Fedroa 37 machine on my framework laptop.

Following this guide [GUIDE] Linux battery life tuning - Linux - Framework Community


Following this part, I’m trying to check if PSR is enabled. However, the directory /sys/kernel/debug/dri/0

does not exist for me

[root@my-laptop dri]# whereami
/dev/pts/0 /sys/kernel/debug/dri my-laptop
[root@my-laptop dri]# ls
1  128
[root@my-laptop dri]# 

Why is this happening, and how can I fix this?

Thanks for any help!

sudo sh -c "cat /sys/kernel/debug/dri/*/i915_edp_psr_status"
