Or any kind of RDNA?

[VisualEhrmanntraut]

Well... yes

[ghost]

Wdym by that tho? What rdna igpu?

RDNA 2 is used in the Steamdeck and newer AMD CPU’s, since Vega was supported we were hoping it’d be relatively easy to have a testing branch for RDNA so that we could enable graphics acceleration

[AriKorpus]

Would this mean 7040 series igpu support? Also do we know a general timeline for how long it will be until we reach a beta of this milestone? Will it be months or years?

RDNA3 is unsupported in macOS

@ChefKissInc I have a lenovo laptop with a 6800HS processor and it works fine now except for my rDNA GPU. When will the beta version be available? I would like to be a tester if I can. Thanks.

[VisualEhrmanntraut]

We're only 3 people; be patient, we'll get to it eventually.

In a galaxy, far far away:

i know there is no news about a release for my hardware yet but i just wanna say the output already works i dont know much about this kinda stuff so i dont really know if this is an accomplishment
i was able to get it working without gpu acceleration soooo atleast the output already works :) but when i place the nootedred kext and update with propertree it boots to opencore menu then i select the disk and it just reboots and next time it gives a error and google says it's called a "kernel panic"
laptop:
asus tuf a15 2022 ryzen 7 6800h rtx 3050 and radeon 680m [rtx disabled]

[VisualEhrmanntraut]

x86_64 computers have a fallback for output called VESA. If the GPU required a driver to merely display some pixels on the boot display, how'd things like OpenCore work?

[ghost]

As i said i dont know much about this stuff
So i think this is really interesting
Also did you make any progress?
And Also how did you respond so fast lol

[VisualEhrmanntraut]

Also how did you respond so fast lol

Okay so let's say, hypothetically, notifications existed, and I were to, hypothetically, receive one about this thread

[VisualEhrmanntraut]

Also did you make any progress?

I'm working solely on Van Gogh at the moment. It seems to be more work than I anticipated; things like the bandwidth bounding box, clock manager, and potentially other things (hopefully not) differ in implementation. We were lucky about HWLibs supporting the Van Gogh family, but the framebuffer/display controller (AMDRadeonX6000Framebuffer.kext, which is basically a port of DC (Display Core)) does not; so there's no DCN (Display Core Next) 3.0.1 (what Van Gogh uses) implementation.

so not radeon 680m rembrandt?

still curious about this

[VisualEhrmanntraut]

@ThijsGaming iGPUs other than Van Gogh are DCN 3.1, which needs another 1 thousand lines of code back ported from Linux to these kexts. Expect several more months of delay for those

[ghost]

ok i will just wait then thanks for even making this project i think it's really cool!

[pituslandia]

I just noticed this thread now says enhacement. Doest that mean VanGogh is now working with nootedred?

[VisualEhrmanntraut]

@pituslandia Yes 100% real no virus no survey working 2024 you must give me 500 dollars for special version in bitcoin and your home address

[VisualEhrmanntraut]

Update: After further analysis, there is no PowerPlay, Hardware Manager logic in HWLibs either. It is redirected to dummy PP. Catalina is the only one with code, but that version does not support RDNA 2 & it's also only code for Van Gogh. I am not sure if I want to do this anymore.

[VisualEhrmanntraut]

This will be done in a new kext to reduce complexity and ensure the code does not cluttered.

[VisualEhrmanntraut]

In progress.
