Sure, that's easy. I didn't do it because I assumed it would not matter. Since the RR scheduling quantum is considerably longer than the basic 1.45msec audio cycle, it should work exactly the same. I'll cobble together a JACK version to try that for you. > Second the patch I sent you is fine for testing; I was hoping you > would try it.

This would be the isoprio3 patch you posted? Do I have to use 2.6.11-rc1-mm2, or will it work with 2.6.11-rc1? -- joq - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
