The user is experiencing a segfault with qemu-arm in user mode after upgrading to QEMU 2.11.x. They're using uclibc-ng chroot for building software targeting Raspberry Pi. + +Looking at the details, the problem started after updating from 2.10.1 to 2.11.1. They did a bisect and found that changing MAX_RESERVED_VA back to its previous value fixed the issue. The fact that it only happens with uclibc-ng but not glibc or musl suggests something related to how QEMU interacts with different C libraries, maybe in memory management or address spaces. + +The segfault occurs when running Python and importing portage. The backtrace points to cpu_tb_exec and static_code_gen_buffer, which are parts of TCG (Translation-Cache Generator) execution, used for just-in-time compilation of machine code. This is part of the user-mode emulation in QEMU. + +The mention of MAX_RESERVED_VA makes me think about how the address space is reserved. Changing this variable likely affects memory allocation or reserved areas, which could be causing a conflict with uclibc-ng's runtime environment. Since it's user mode and not involving KVM or hypervisor features, it's more about the emulation layer. + +The error occurs in the TCG code, so it's related to how QEMU translates the target architecture (ARM) into the host IR (x86_64 in this case). This falls under 'mistranslation' because it's an issue with the semantic mapping from source to target. Alternatively, it could be an assembly lowering problem if it's during code generation. + +But since the root cause is traced back to a specific variable change related to reserved VA space, which affects memory layout and address translation, I think 'mistranslation' might not capture it fully. However, considering that the issue arises in TCG code execution and relates to how memory addresses are handled during translation, perhaps 'assembly lowering' or 'mistranslation'. + +Wait, 'mistranslation' refers more to incorrect mapping of instructions, whereas this seems to be a problem with address space reservation affecting generated code. But since it's causing a segfault in the TCG execution, maybe it's better classified under 'mistranslation' as it's part of the translation process. + +Alternatively, if it's about how the target machine's memory is being mapped or reserved, it might be more about device-related issues, but that doesn't seem to fit. Looking at the possible categories again: 'mistranslation', 'assembly lowering', and others. Since it's related to TCG code generation and execution, I think 'mistranslation' is appropriate because it's a problem in the translation layer. +</think> + +mistranslation \ No newline at end of file |
