Or do I just mix something up? I think, this wiki and maybe Ubuntustudio as well are using a very confusing terminology. Generally we have two kinds of kernels: The "vanilla" kernel as downloadable on kernel.org and the same kernel, but patched with Ingo Molnars RT-patches. The vanilla kernel, if configured properly with CONFIG_PREEMPT etc., already gives very good performance in the low latency department, enough for many users, even audio users. I run one of these. If you want more, then you can install a RT-patched kernel, as is provided in the linux-rt or linux-realtime packages. I would call the Ingo-Molnar-patched kernels Realtime-Kernels or Low-Latency-Kernels. I would not call the vanilla kernel a "low latency" kernel. It's just a vanilla kernel configured with CONFIG_PREEMPT, which happens to have good low latency performance as well. But that alone shouldn't be taken to give it a different name. It has good network performance, too, but I still wouldn't call it a "network kernel" and it supports USB keyboards, but still it's not a "USB keyboard kernel". That's a bit silly. ;) Ciao -- Frank Barknecht _ ______footils.org__ _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
