Linux Workaround Coming For Better s2idle Resume On More AMD Lenovo Laptops

[lethalwp]

I never had so many issues with other brands :-(

i assure you, other brands also have problems:
on some fujitsu-intel laptops:
-screen doesnt turn on when using a rhel 8 kernel 4.18iirc, fixed in other kernels but not backported.
-on fuji 5511. laptop keyboard doesn t work in gfx on 5.17 kernel (fedora 36). seems fixed in 5.18rc0
-kernel panics at shutdown on 5.17, seems fixed in 5.18
-still a bad kernel message at boot on 5.18
- closing the screen also wakes up from sleep

most of the brands just ignore the linux world i hope this will change

Thats exactly the issue that I see on my new Lenovo IdeaPad 5 Pro 16ACH6. Ok it was worse already, before linux 5.17 it needed 30 seconds to turn on the display after sleep, now its ca. 10. seconds, but wireless (even with Intel wifi) is not available until the next reboot. I never had so many issues with other brands :-(

I'd rather have S3/deep/s2ram back than this Windows nonsense; unfortunately many laptops have S3 kicked out of firmware, sadly seeming AMD ones especially.

So first Lenovo took the time to develop this SMI and now someone had to spend time developing a way to disable it.

Fucking closed source firmware!
