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 192.168.50.25
[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!
