AMD Begins Adding "GFX950" GPU Support To LLVM For Next CDNA Accelerator


As of today the first handful of commits have landed in LLVM Git ahead of next year's LLVM 20.0 for beginning to enable the AMDGPU compiler back-end for 'GFX950', the next iteration of the CDNA family for Instinct accelerators.

Given the patches are still in the preliminary stages and more enablement of any new instructions and similar may still come, it's difficult to definitively say whether AMD GFX950 is the MI325X or MI350 accelerator parts. This commit lays out the initial AMD GFX950 target without revealing which Instinct product(s) are GFX950. Great to see the AMD GFX950 enablement started for whatever Instinct product(s) this ends up correlating to but presumably the Instinct MI350 due for release in 2025... We'll see in the days/weeks ahead what more GFX950 enablement code lands in upstream LLVM ahead of the LLVM 20.1 release around March.
