Hello everyone, After an initial failure in February this year I have now gotten my Blizzard SCSI Kit IV to work with the esp_scsi core. It turns out the DMA engine doesn't like a transfer size of only 2 bytes (at least not when receiving). The bytes were in the FSC FIFO, but didn't get transferred to DRAM and the final interrupt didn't occur so the driver got stuck. The old driver used to do such small transfers using PIO, so that is what I do now in the glue driver. What is the way to go? Revive the glue named drivers/scsi/blz1230.c? Or should it be renamed? Some of the other drivers may be a little more problematic because they had more driver operations which are not present in the esp_scsi DMA abstraction. Kind regards, Kars. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
