You said "all current mainline drivers using the library use cyclic DMA." Does this mean the following drivers use "snd_dmaengine_pcm_open" ? ep93xx-pcm imx-pcm-dma-mx2 mxs-pcm However, the following drivers don't use any ASoC DMA framework, right ?. E.g. these drivers call dma_request_channel directly. siu_pcm fsi txx9aclc That is to say, some drivers ASoC DMA framework. However some drivers don't use any ASoC DMA framework. Why didn't you do porting to your saying "ASoC DMA framework"? thanks. -- ROHM Co., Ltd. tomoya -- 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/
