Well, it depends on the application. In the automotive box I've shown the barebox based boot optimizations for in my ELC-E talk, the task is to get CAN communication running in < 200 ms. For that kind of application it's useful to be in userspace as fast as possible, just in order to have one socket-can application running, and everything else comes later. rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
