It is only useful if Oprofile is implemented on top of perfmon2. It is used by Oprofile tools to detects which interface to use so that they can be used with older kernels as well. But for now, I am shooting for Oprofile using its own kernel code and /dev/oprofile interface. That will provide for a smoother transition. -- -Stephane - 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/
