The user provided a bug report related to QEMU's user-mode emulation on ppc64le. The issue is with Go's time functions like NewTicker and Sleep not working correctly when using vDSO for clock_gettime. The problem appears in Go 1.12+ but not in 1.11, and it's specific to QEMU's user mode, not actual hardware or other architectures. + +The key point here is that the problem is suspected to be in QEMU's handling of vDSO calls for clock_gettime. The user mentions that when Go switched to using vDSO for PowerPC64 in 1.12, the issue arose. The symptoms are that sub-second timers aren't working—they're defaulting to 1 second. The question is whether the nanoseconds part is lost in vDSO calls via QEMU's emulation. + +The categories to choose from are instruction, syscall, or runtime. The bug seems to be related to how QEMU emulates the vDSO for clock_gettime. Since vDSO is a mechanism that allows certain system calls (like clock_gettime) to be handled in user space without a full context switch to kernel mode, the issue here is with the emulation of that specific system call's vDSO version. The problem isn't with the instruction set emulation per se, but rather how the system call (specifically the vDSO version) is handled. The runtime category is for other runtime errors, but since the issue is tied to a syscall's vDSO implementation in QEMU, the correct category would be syscall. +</think> + +syscall \ No newline at end of file |
