I've heard this isn't possible on AMD unfortunately.

I'm on an AMD machine that System76 wrote the firmware for, and they specifically wrote in S3 sleep functionality despite the base firmware missing it.

Hopefully it can find it's way to Framework.

		The firmware vendor contracted System76 to develop the feature specifically for Linux compatibility. I'm unaware of how much access Framework has to the underlying firmware blobs. If they don't have source/license/keys/etc for the right parts, they might be at the mercy of their own vendors for S3 support.
