I can't, for love nor money, find a way to get a vmlinux-uncompressed-with-symbols image for oprofile to use with my running F10 kernel. They ship kernel images compressed, and without symbols, and the older information on this (ca FC6) doesn't appear to work anymore--there's no "core-debuginfo" and "kernel-debuginfo" packages to install.
So, to a first approximation, oprofile is next-to-useless for me. (Although it does helpfully tell me that the kernel and libgnuradio-core are the top two CPU users, but I'd really like more detail than that :-) ). -- Marcus Leech Principal Investigator, Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
