Although the record is short (a few minutes only), It can help to analyse scheduling algorithm efficiency and also driver timing issues. The user can access data from user-space, through proc filesystem and analyze it with a graphics tool. Then, since it's also availlable within KDB, it can give clues and help for debugging. So far, the tool is not a big deal, but not trivial either. When It is running, the tool doesn't overload the system. And when it is not running, it's just transparent. I did a webpage for it, you can check it out at: http://membres.lycos.fr/kernelanalyzer/ If you have any comment/critics, don't hesitate to share it Thanks, Sylvain - 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/
