Update on AMD GPUs and Libre Kernel
- Vous devez vous identifier ou créer un compte pour écrire des commentaires
Last year we got to the point where I could adjust refresh rate and resolution on many AMD GPUs that were in the R* 300 series and older using the libre kernel. Previously I had zero success on AMD GPUs. I couldn't game much on them though for 3D games. Super Tux Kart on my R9 270 was basically a slide show. I tried my R9 270 today on the new 6.9.0-gnu kernel and was able to get up to 15 FPS on Super Tux Kart. 15 FPS isn't great but it's 15 frames more than I was getting before. I also am able to get my RX 590 to boot where before kernel 6.9.0-gnu it just gave an error message at startup. I can't adjust refresh rates or resolutions on the RX 590 still but progress is progress.
I have an AMD GPU in my Talos II and unfortunately it does not work at all with linux-libre. This is different from x86 where the non-free BIOS loads the firmware before the OS starts. When I use linux-libre, I also use my X200 laptop or some of those SBCs from https://www.fsf.org/resources/hw/single-board-computers. My long term goal is to develop a GPU that respects users freedom, that is usable for both mobile and desktop VR. For my use case NVIDIA is even worse, since most GPUs that I have tested do not work with the POWER9 at all. I won't buy the Steam Deck, even if it can run Guix and move to OpenPOWER and ARM long term. I think that VideoCore can be liberated.
Did you test NVIDIA working with nouveau as Kepler series on Talos II?
"I have an AMD GPU in my Talos II and unfortunately it does not work at all with linux-libre. "
I seem to recall you having the 5700 XT, am I correct ?
"My long term goal is to develop a GPU that respects users freedom, that is usable for both mobile and desktop VR"
I'm wishing you well on the Libre-SOC project and donating when I can !
I heard someone talking on IRC at talos channle, saying that Nvdia is removing powerpc support completely in the coming months.
Why were you thumbed down for this? Is this a misleading comment or something? Or misinformed?

I have always liked playing STK in slideshow mode. You get to do things you would never dare doing in continuous mode.
