MeeGo's kernel is not PREEMPT_RT. For several good reasons, MeeGo needs a 2.6.35 kernel, and there currently is no -rt patch for that kernel. At the moment, pro audio performance on MeeGo is bad because of CPU frequency scaling. However, if you disable it[1] I'm getting good RT performance from MeeGo. -gabriel [1] One way is to recompile the kernel with some different config options. _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
