Slackware's +kernel does not have a realtime kernel, you will have to compile it. + +You still can profit when jackd runs with realtime privileges. +One way to do this on Slackware would be to use set_rlimits (not part of +Slackware). Since 12.2 there's another way, though experimental. +If you have a filesystem that supports posix capabilities (reiserfs does not), +you can grant jackd the rights to run in realtime mode, even when started as +normal user with the following command: + + # setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/jackd + +The post-install script of the jack package runs this exact command, +so that you do not have to. |
