1da177e4 | 53 | * |
4bd6d7f3 MW |
54 | * 1. Although all of the necessary command mapping places have the |
55 | * appropriate dma_map.. APIs, the driver still processes its internal | |
56 | * queue using bus_to_virt() and virt_to_bus() which are illegal under | |
57 | * the API. The entire queue processing structure will need to be | |
58 | * altered to fix this. | |
59 | * 2. Need to add memory mapping workaround. Test the memory mapping. | |
60 | * If it doesn't work revert to I/O port access. Can a test be done | |
61 | * safely? | |
62 | * 3. Handle an interrupt not working. Keep an interrupt counter in | |
63 | * the interrupt handler. In the timeout function if the interrupt | |
64 | * has not occurred then print a message and run in polled mode. | |
65 | * 4. Need to add support for target mode commands, cf. CAM XPT. | |
66 | * 5. check DMA mapping functions for failure | |
349d2c44 MW |
67 | * 6. Use scsi_transport_spi |
68 | * 7. advansys_info is not safe against multiple simultaneous callers | |
9d0e96eb | 69 | * 8. Add module_param to override ISA/VLB ioport array |
