Ideally what would be happening here is that you or other people who have such systems would be working to add the required support to the core code, there's clearly a need for common code here as there are a number of different systems that don't have cyclic DMA and it wouldn't be great to end up with duplicated code. Is there some great difficulty in factoring out the support for non-cyclic audio DMA on dmaengine - it seems like if there is we must have a serious problem in dmaengine which we should fix? If there is a substantial difficulty then that's different but it doesn't feel like we've tried doing common code yet, if there's problems doing that I'd like to understand what they are before we jump ahead of ourselves. -- 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/
