We'd also have to make sure that the comparison is between the linux-omap kernel and the OMAPZoo kernel, rather than o-z PIO vs. o-z DMA. The OMAPZoom kernel doesn't post any device register writes. That should cause any driver using PIO to drag, compared to the l-o kernel. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
