I regret that this description is persisting here. "We" (the audio developer community) did not participate because it was made clear that our needs were not going to be considered. We were told that the preemption patch was sufficient to provide "low latency", and that rescheduling points dotted all over the place was bad engineering (probably true). With this as the pre-rendered verdict, there's not a lot of point in dedicating time to tracking a situation that clearly is not going to work. The kernel is not going to provide adequate latency for multimedia needs without either (1) latency issues being front and center in every kernel developer's mind, which seems unlikely and/or (2) conditional rescheduling points added to the kernel, which appears to require non-mainstreamed patches. --p
