ROCm 7.2.0 RDNA2 Support Contribution

[Maxritz]

Hi @lamikr,

I've been working on extending rocm_sdk_builder to support ROCm 7.2.0 for RDNA2 GPUs (RX 6700 XT and gfx1030-1032 family).

What I've built:

Complete patch set for all 16 ROCm 7.2 libraries
FP8→INT8 conversion layer (enables FLUX.1/SD3 on RDNA2)
WMMA software emulation using RDNA2's native dot instructions
VGPR auto-segmentation for 256 VGPR hardware limit
Comprehensive documentation (build guide, troubleshooting, optimization guides)
The work is ready in my fork: https://github.com/Maxritz/rocm_sdk_builder/tree/rocm-7.2-rdna2-support

I'd like to contribute this back to rocm_sdk_builder. Would you be open to reviewing a pull request? I'm currently testing the build on my RX 6700 XT system and can provide benchmarks/validation results.

This would enable millions of RDNA2 GPU owners to use ROCm 7.2 and modern FP8 models on consumer hardware.

Let me know if you'd like me to open a PR or if you have any questions about the implementation!

Best regards, Maxritz

I still have to test it . I will share some udpates , but i think anyone else here can also use this to make things work further

G'day, not sure this repo is still being maintained... -> https://github.com/ROCm/TheRock

Yes the official ROCm one is. See how you go, but you may have better luck contacting maintainers directly...
