Okay, I'm trying to figure out whether this QEMU crash in Docker on Apple Silicon is a user-mode or system-mode issue. Let's break down the problem.
The user is running a Docker container using Docker Desktop on an Apple Silicon machine (which uses ARM64 architecture). The Dockerfile they're using is based on balenalib/rpi-raspbian:bullseye-20210925, which targets a Raspberry Pi, so it's for an ARMv7 or similar CPU. When they run the container, QEMU crashes during the emulation of ARM (not ARM64).
I know that Docker on Apple Silicon can handle different architectures through QEMU emulation. However, since the host is ARM64 and the container is ARM, there might be some issues with how QEMU is handling this translation.
The problem occurs when executing user commands inside the container. The crash happens during an apt-get update and upgrade, which are standard system operations but involve running executables and scripts.
Since the issue arises from running software inside the container (user space) rather than something at the kernel level or hardware interaction, it seems like a user-mode problem. User-mode issues typically involve how applications run within the environment, not the underlying OS or hardware.
Additionally, if this were a system-mode issue, we might expect problems with device drivers or higher-level privileges, but here the crash is more about executing userland processes in emulation.
