The user provided some code and an example where using SME FMOPA instruction gives incorrect results when using tile 1 instead of tile 0. Let me think through this step by step. + +First, looking at the problem description: When they perform an outer product of a vector filled with 1.0s, it should result in a matrix full of 1.0s. However, they're getting zeros when using za1.s but correct results with za0.s. So there's something wrong with how the tiles are being handled. + +The code provided uses SME instructions. I know that SME (Scalable Matrix Extension) introduces vectorized operations for matrix computations. The FMOPA instruction is used here, which stands for Floating-point Matrix Outer Product and Accumulate. It should compute an outer product of two vectors and add it to a matrix tile. + +In the SML, when they execute the FMOPA with za1.s as the destination, after that, when they read from za1v.s, they get zeros instead of ones. But using za0.s works fine. So this seems like an issue with how QEMU handles the FMOPA instruction when it's written to a specific tile (tile 1 in this case). + +Looking at the steps: They compile and run with QEMU, which is where the bug manifests. The output shows all zeros, meaning that either the FMOPA isn't correctly writing to za1.s or reading from it. + +So, considering the possible categories: +- instruction: Faulty instruction described. +- syscall: Error in system call. +- runtime: Other runtime errors. + +The issue seems to be related directly to how QEMU handles the SME instructions, specifically FMOPA when using tile 1. So this points towards an issue with the instruction handling or the emulator's implementation of that instruction. + +Therefore, it's likely an "instruction" category bug because it involves incorrect behavior of a specific assembly instruction within QEMU. +</think> + +The problem relates to how QEMU handles the SME FMOPA instruction when writing to a specific tile, indicating a fault in the instruction processing. + +instruction \ No newline at end of file |
