I've got an HP Chromebook which now has vanilla coreboot on it, and can boot any EFI operating system. I loaded it up with Devuan, I think starting with the oldstable (basically bullseye) and at some point I installed the firmware-amd-graphics package.
All of the sudden, my glmark2 score went from 80 - 100 points, to >800 points.
Now, I can't figure out what combination of kernel & firmware packages I had to achieve working 3D acceleration to save my life. After I got the Glmark score in the 850s range, I was able to do full screen full resolution open arena silky smooth. With no firmware, it is an absolute slide show, even in a tiny window. Probably less than 10 fps. With the firmware installed, it is very slow, but not a literal slideshow. Full screen 1280x720 is probably 20 - 25 fps, whereas before it was literally full speed silky smooth. It would go full speed, busy scenes without a single hiccup. Buttery smooth, probably a solid 60+ fps though I never checked.
I don't know when this stopped working, because I don't use this little chromebook for games == I mostly use it for SSH and light surfing. But now it is dog slow in firefox.
I've tried multiple re-installs of Devuan and Debian. Both on Stable, and old-stable. Even tried "testing" on both. No luck!!
Also tried fedora, ubuntu mate, I can't get proper HW 3D working. The driver does load, but the performance is crap.
What might I be doing wrong? It bugs me so much because I had it randomly working by pure luck, and no matter how much I try I can't seem to get the good results again.
Hardware specs:
AMD A4-9120C Dual Core 1600 MHz /w AMD Radeon R4 3 core @ 600 MHz -- AMD Stony Ridge APU
4 GB RAM
It is an HP 11A G6 EE Chromebook, codename grunt / barla

I'm not sure, but I *think* I had the good results while using something newer than 6.1 but older than 6.6. Perhaps 6.2.x?
