Thanks very much to everybody who has been helping me with this problem.
I can now confirm that the way to get realtime-lsm working on Gentoo (with a
2.6 kernel) is to put the line
options realtime gid=n
(where n is the numeric id of the group to be allowed realtime scheduling)
into /etc/modules.d/realtime, and to put the line
realtime
into /etc/modules.autoload.d/kernel-2.6 if you want the realtime module loaded
at startup.
For those who don't know, the numeric id of the group will be listed
in /etc/group. I used the kde control center put user 'robert' into group
'audio' and I give audio (numeric id = 18) realtime priveleges. You could if
you wanted create a special group called 'realtime'. That would make sense
if you were also doing non-audio things that needed realtime priveleges, such
as microsurgery.
Run modules-update and then run "modprobe realtime" if you want to get it
going without a reboot.
And the mlock=1 option is indeed the default and doesn't need to be specified.
Wasn't mlock how they killed Socrates?
