I tried various modifications to the PTX to keep the cache-hint, but it did not work. |

Thanks for fixing this, I validated the fix with the reproduction in neuralmagic#187. Always great to see fixes that make things simpler ❤️

This PR addresses the Marlin kernel H100 crash that was reported here: neuralmagic#187. The reason for the crash was the inline PTX assembly that introduced the async_copy with streaming behavior. The solution is to use the more standard PTX for async_copy (without the fractional L2 policy for "evict_first"). There is no performance difference between standard async_copy PTX and the previous one.
