The binary is supposed to print "hello, world" and exit, but instead, it just loops forever with 100% CPU usage. + +First, the user mentioned that they compiled OCaml from source, applied a patch, and then ran some commands to generate the test binary. So the issue might be related to how QEMU is handling certain instructions or system calls that the OCaml program makes, especially since it's an interpreted language with its own runtime. + +The possible categories given include things like mistranslation, assembly lowering, device, graphic, network, KVM, etc. The problem seems to occur in user-mode because it's a userspace emulator, so maybe it's related to how the binary is being translated or executed by QEMU's CPU emulation. + +Looking deeper, the binary works on real hardware but not in QEMU suggests that there might be some specific instructions or behaviors that are handled differently in QEMU's environment. Since the program loops indefinitely and uses 100% CPU, it could be an infinite loop due to incorrect handling of certain operations by QEMU. + +I'm considering whether this is a mistranslation issue where the semantics from Arm64 to the target (like x86_64) are incorrect in user-mode. Alternatively, it might be related to how assembly is being lowered during translation. But since it's running on userspace, maybe it's not about the hypervisor or kernel but rather the emulation of the CPU instructions. + +Another angle is looking at whether the issue could be with system calls that the OCaml runtime makes. If QEMU isn't properly emulating certain syscalls, that might cause unexpected behavior. But the categories don't include specific syscall issues, so perhaps it's more about instruction handling. + +Given all this, I'm leaning towards "mistranslation" as the category because it directly relates to how source architecture instructions are mapped in user-mode. +</think> + +The issue is likely due to incorrect translation of Arm64 instructions to the target architecture (like x86_64) by QEMU's userspace emulator. This would fall under **mistranslation**. + +**Answer:** mistranslation \ No newline at end of file |
