The concept may become interesting when more audio software makes use of multiple processors and rt-preemt is already built into the kernel. I suppose that many of the lessons they're learning will be useful for developing a new scheduler for Linux at some point, but it's very far from being useful for linux-audio in the current stage. 2c, robin > -michael > > > > > _______________________________________________ > Linux-audio-dev mailing list > [email protected] > http://lists.linuxaudio.org/listinfo/linux-audio-dev _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
