The DMA setup early on may save time if the next phase is indeed DATAIN or DATAOUT - if a command disconnects the DMA just won't be started. I would have thought the DMA setup could just as easily be done inside NCR5380_transfer_dma instead of splitting it in DMA setup and DMA start - any particular reason for this, Sammy?
Doing the DMA setup early on may not work for atari_NCR5380 given merge_contiguous_buffers() takes place prior to NCR5380_transfer_dma() and may alter the length of the tranfer. (sun3_NCR5380 doesn't have merge_contiguous_buffers()). -- -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
