Define ARCH_DOES_POSTED_DMA, and override the dma_flags_set_dmaflush function. Also define dma_flags_get_direction, dma_flags_get_dmaflush to retrieve the direction and "dmaflush attribute" from flags passed to the sn_dma_map_* functions.
Hi Arthur, I'm a little concerned about changing the API for the dma_ foo functions, which are defined cross platform. If you want to change that, I think it will require updating the documentation explaining it. Regarding ARCH_DOES_POSTED_DMA, is that sufficient as a #define or does it have to be run-time tested? (does it do anything at this stage). I ask since not all ia64 platforms do posted DMA.
