The user is encountering an "Illegal instruction" error when using `numactl --cpubind=0 --membind=1` with QEMU for simulating CXL DRAM. They've provided steps to reproduce and some additional info. + +First, the issue occurs when they try to run a command (`ls`) bound to node 1, which is their simulated CXL memory. When they bind to node 0, it works fine, but node 1 causes an error. The error message mentions "invalid opcode," suggesting that something in the code isn't compatible with the CPU. + +They're using a Xeon III processor, which doesn't natively support CXL. They're wondering if this is the root cause or if it's a configuration issue. If their CPU can't handle the instructions, QEMU might not be emulating them correctly, leading to the illegal instruction error. + +Looking at the possible categories: 'mistranslation' relates to incorrect mapping from source to target, which could happen here if QEMU isn't translating CXL instructions properly when bound to node 1. Alternatively, it's a hardware limitation (not covered in 'mistranslation'), but since they're using QEMU, the error is likely due to how the emulation handles the binding. + +So, the bug seems to stem from incorrect handling of CXL instructions when memory is bound to a specific NUMA node, pointing towards an issue in the translation layer. +</think> + +The bug report involves running `numactl` with certain bindings leading to an illegal instruction error.
