My only thought was that the intent must have been to allow compilation of a driver that checks for DMA at runtime (via dma_supported). But, I guess dma_supported is intended as a platform-level check? If the DMA availability is at the arch level then such a driver could use (albeit ugly) compile flags to cover that situation...? Well, either way is fine with me. John -- John W.
