Let me go through the problem step by step. + +The issue is about QEMU not correctly emulating the strict alignment requirements of the 68000 processor. When running a kernel on real hardware, it locks up due to unaligned memory accesses that should cause an address error but don't in QEMU. The user had to debug using GDB and found that memmove was called with an unaligned pointer. + +Looking at the stack trace, the problem occurs in the memmove function within the kernel's code, specifically during a move operation. This suggests it's happening in the operating system or kernel space rather than a user application. + +The disassembly shows a word store instruction where the source address is not aligned, which on real hardware would cause an address error. The fact that QEMU doesn't catch this indicates an issue with how QEMU emulates the CPU's behavior, particularly in handling memory alignment. + +Since the problem involves the kernel and affects system-level operations like early console setup and memory management, it seems to be related to how QEMU handles low-level hardware interactions and exceptions. This is more about the emulator accurately reflecting the target architecture's behavior for the operating system to run correctly. + +Therefore, this bug is likely system-mode related because it involves higher-privilege code (kernel), device handling, and the interaction between the OS and the CPU. +</think> + +system \ No newline at end of file |
