The user is reporting a problem with the AArch64 SME SMOPA (4-way) outer product instruction. They provided a Python example that shows the expected result, but when they run their assembly code using QEMU, the output is incorrect. + +First, I need to understand what the SMOPA instruction does. According to the spec link they provided, SMOPA is for signed integer sum of outer products and accumulate. The Python example seems to compute a matrix multiplication where each element C[row][col] is the sum of products of elements from A and B, with some indexing. The assembly code is supposed to replicate this using SME instructions. + +Looking at the assembly code in foo.S, they're setting up vectors A and B using the index and add instructions. Then they use smopa to compute the outer product and accumulate into the tile register za0. After that, they read from the tile and store the results into memory. + +The problem is that when they run this code under QEMU, the output doesn't match the Python example. The expected output has four rows with specific numbers, but the actual output from QEMU shows some correct values (like 110, 478, etc.) but others are zeroed out. For example, the second row is all zeros, and the fourth row is also zeros. This suggests that the SMOPA instruction isn't computing all the required elements correctly in QEMU. + +Since the issue only occurs when running under QEMU, and the code works as expected in the Python simulation, the problem is likely in how QEMU emulates the SMOPA instruction. The user is using QEMU with SME enabled (-cpu max,sme128=on), so the bug is probably in QEMU's implementation of the SME SMOPA instruction. The categories given are instruction, syscall, or runtime. Since this is about an instruction's incorrect behavior in QEMU, the correct category is "instruction". +</think> + +instruction \ No newline at end of file |
