Good work! On a related note, would it make it easier/possible to start thinking about if FreeBSD can export CPU cache information into userland? Some applications want these bits... Linux exports them via sysconf(3), back in 2003 bms@ proposed preliminary design [1] and suggested sysctl(3). ./danfe [1] https://lists.freebsd.org/pipermail/freebsd-hackers/2003-October/003604.html _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
