[PlanetCCRMA] Re: FC3 ccrma runs very very slow.

[Bal Dobe]

One caveat is that for realtime schedulling access as a normal non-root
user
you will need to either install the Planet CCRMA version of "pam" (part
of planetcore, pam-0.79-9.6.2.rhfc4.ccrma), 

How do |I do this Fernando?

or


"edit /etc/security/limits.conf to give everyone (or a group) access to
realtime priority. The relevant part of Planet CCRMA's configuration is:

*               -       rtprio          99
*               -       nice            -10
*               -       memlock         4000000"

Here is my limits.conf file but what are the changes that I need to make
to enable an ordinary user to have root privelages so that the audio
apps can be run in real time?



"What hardware do you have? It may be too new for proper support by the
linux kernel and that's why you are getting so much grief from it."

Will get back to you on this one but it all was bought around Nov 2004
and was very new then.

Yes, that should be possible. I have not tried it but it should work.
Just don't add the "planetcore" repository to the apt configuration. One
caveat is that for realtime schedulling access as a normal non-root user
you will need to either install the Planet CCRMA version of "pam" (part
of planetcore, pam-0.79-9.6.2.rhfc4.ccrma), or
edit /etc/security/limits.conf to give everyone (or a group) access to
realtime priority. The relevant part of Planet CCRMA's configuration is:

*               -       rtprio          99
*               -       nice            -10
*               -       memlock         4000000

What hardware do you have? It may be too new for proper support by the
linux kernel and that's why you are getting so much grief from it.
