The catch is that there seems to be no obvious way to do something different for the RTAI kernel than for the normal kernels. You can easily decorate *all* the kernels using something like GRUB_CMDLINE_LINUX isolcpus=1 However, I'm using the same Atom box to run a Thing-O-Matic 3D printer as well as the Sherline mill (not at the same time). The process that converts solid models into printable G-Code requires as many CPU cycles as it can possibly get, so it's highly desirable (nay, verily, vital) to *not* throw away half the CPU when I'm not using EMC. So I boot into the RTAI kernel for EMC2 and the stock Ubuntu kernel-of-the-month for the Thing-O-Matic. What I need is something that recognizes the RTAI kernel and applies isolcpus=1 to it. That seems to be beyond Grub2, although I'm sure somebody with serious Bash-fu could write a script filter... -- Ed http://softsolder.com ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
