Perhaps it silently falls back to > cpu-clock? Yes i'm sure. I was actually debugging some kernel pebs code, and had a heavily instrumented pebs code path and was first trying to figure out what went wrong in the kernel, until I realized that the userland was broken. Does :p work for anyone else? BTW I hope the perf userland becomes more stable again. Recently I've had far more trouble with the user binary than the kernel driver, which is unusal. -Andi -- ak@linux.intel.com -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
