Perhaps I'm missing something, but I don't understand the purpose of this patch. If the device can do DMA SG, why use videobuf2-dma-contig and not videobuf2-dma-sg? What would be the difference design-wise between them if this patch is merged? -- Best regards, Pawel Osciak -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
