This is a really long winded and long standing offtopic gripe I have with general application development under Linux. The only way I'm going to get folks to understand my position on it is if I code it up in my implementation language of choice with my own APIs. There's a TON more that can be done with QoS in the kernel (EDL schedulers), DSP JIT compiler techniques and other kernel things that can support pro-audio. I simply can't get to yet until the RT patch has a few more goodies and I'm permitted to do this as my next project. I had a crazy prototype of some DSP graph system (in C++) I wrote years ago for 3D audio where I'm drawing my knowledge from and it's getting time to resurrect it again if I'm going to provide a proof of concept to push an edge. Also, think, people working with the RT patch are also ignoring frame accurate video and many others things that just haven't been done yet since the patch is so new and there hasn't been more interest from folks yet regarding it. I suspect that it's because that folks don't know about it yet. bill - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
