The user is reporting that QEMU-arm hangs when running a Go test program. The environment is Ubuntu 16.04 on x86_64, using QEMU-arm version 4.2.0. The Go version is 1.14.1 for Linux ARM. The test program is a simple loop that prints "Hello world" 1000 times. They ran the test 500 times, and the hang occurred once around the 200-300 mark. They provided a strace log, but I can't see it here. + +First, I need to figure out what category this falls into: instruction, syscall, or runtime. + +QEMU emulation issues can sometimes be due to incorrect handling of specific instructions (instruction category). However, the problem here seems to occur during execution of a Go program. Go has its own runtime, which manages things like garbage collection, scheduling, etc. If the hang is happening within the Go runtime, maybe during some internal operation, that would be the 'runtime' category. + +Syscall issues would involve system calls made by the program. The test program uses fmt.Printf, which eventually makes system calls like write() to output the text. If QEMU is mishandling a particular syscall, that could cause a hang. But the user mentioned that the issue occurs sometimes, not every time, which might point to a race condition or something in the runtime. + +Since the problem is intermittent and happens during the execution of the Go program, especially considering Go's concurrency features or runtime management, it's possible that the Go runtime is interacting with QEMU in a way that causes a deadlock or infinite wait. For example, maybe the garbage collector or some goroutine scheduling is causing QEMU to stall. + +Another angle: QEMU versions prior to 4.2 might have had issues, but the user is on 4.2.0. However, there might be specific ARM instructions or syscalls that Go uses which are not properly emulated, leading to a hang. But the fact that it's intermittent makes me think it's not a straightforward instruction error. + +Given that the problem occurs during the runtime execution of the Go program and considering the possible interactions between the Go runtime and the emulator, I'm leaning towards the 'runtime' category. The issue might be related to how QEMU handles certain operations that the Go runtime depends on, like threading or specific CPU features. +</think> + +runtime \ No newline at end of file |
