gfx12 support

Awesome project! Are there any plans for RDNA4 support in the future?

Hey funny you posted this around the time I was trying to download some ISA docs and map the differences between what I have now and what I need to make it compatible.

Yes! I will be supporting RDNA4 (GFX12). I hope it won't be a massive lift, but I can get it done

Awesome news, thank you! Looking forward to RDNA4 support.

I won’t say anything negative about Nvidia, but it’s great to see projects that help broaden competition in the AI space.

Hello!

I've added RDNA4 support now you can run it using --gfx1200.

Please let me know if you have any questions or run into any issues. stayed up a bit last night and thought I'd crank this out.

I assume this means that all RDNA4 GPUs should use --gfx1200, even though gfx1200 corresponds only to the RX 9060/XT.

Hello that is correct, RDNA4 GPU's dont differ too strongly from the ISA spec but if there is an issue, please feel free to raise one or let me know.
