In wd719x_queuecommand(), "scb" is mapped to streaming DMA: scb->phys = dma_map_single(..., scb, ...);
Then "scb" is accessed at many places in this function, such as: scb->SCB_options |= WD719X_SCB_FLAGS_AUTO_REQUEST_SENSE; ... scb->data_length = 0; scb->data_p = 0; These accesses may cause data inconsistency between CPU cache and hardware. I am not sure how to properly fix this problem, and thus I only report it. Best wishes, Jia-Ju Bai
