…triton-lang#6131) This PR addresses a compilation issue when targeting RTX 5090 GPUs with compute capability 120. Previously, the function getMMAVersionSafe would trigger an assertion failure for compute capabilities beyond 110. This update ensures that GPUs with compute capability of 120 fall under a valid MMA version category, preventing unnecessary assertion failures. Changes Updated the compute capability check in getMMAVersionSafe to handle GPUs with compute capability up to 129. Assigned MMA version {2} for these cases to maintain compatibility with customer's gpus only supporting version 2. Motivation Certain GPUs, including models from the NVIDIA 50 series, have a compute capability of 120, which was previously unhandled, causing compilation failures. This fix ensures compatibility with such GPUs. <!--- The core Triton is a small number of people, and we receive many PRs (thank you!).
