That's why q-syscollect doesn't require any of this. No reboot, no kernel modules. If you have access to an itanium 2 machine, you really might want to try it. (Yes, q-view, the tool to generate gprof-like output requires guile 1.6/slib. It comes standard wiht Debian.) --david - 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/ | ||||||||||||
