22 | /* All GDT Disk Array Controllers are fully supported by this driver. | |
31481455 | 23 | * This includes the PCI SCSI Disk Array Controllers and the |
1da177e4 LT |
24 | * PCI Fibre Channel Disk Array Controllers. See gdth.h for a complete |
25 | * list of all controller types. | |
26 | * | |
1da177e4 LT |
27 | * After the optional list of IRQ values, other possible |
28 | * command line options are: | |
29 | * disable:Y disable driver | |
30 | * disable:N enable driver | |
31 | * reserve_mode:0 reserve no drives for the raw service | |
32 | * reserve_mode:1 reserve all not init., removable drives | |
33 | * reserve_mode:2 reserve all not init. drives | |
34 | * reserve_list:h,b,t,l,h,b,t,l,... reserve particular drive(s) with | |
35 | * h- controller no., b- channel no., | |
36 | * t- target ID, l- LUN | |
37 | * reverse_scan:Y reverse scan order for PCI controllers | |
38 | * reverse_scan:N scan PCI controllers like BIOS | |
39 | * max_ids:x x - target ID count per channel (1..MAXID) | |
40 | * rescan:Y rescan all channels/IDs | |
41 | * rescan:N use all devices found until now | |
1da177e4 LT |
42 | * hdr_channel:x x - number of virtual bus for host drives |
43 | * shared_access:Y disable driver reserve/release protocol to | |
44 | * access a shared resource from several nodes, | |
575c9687 | 45 | * appropriate controller firmware required |
1da177e4 | 46 | * shared_access:N enable driver reserve/release protocol |
1da177e4 LT |
47 | * force_dma32:Y use only 32 bit DMA mode |
48 | * force_dma32:N use 64 bit DMA mode, if supported | |
49 | * | |
50 | * The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N, | |
52759e6a | 51 | * max_ids:127,rescan:N,hdr_channel:0, |
31481455 | 52 | * shared_access:Y,force_dma32:N". |
1da177e4 LT |
53 | * Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y". |
54 | * | |
55 | * When loading the gdth driver as a module, the same options are available. | |
56 | * You can set the IRQs with "IRQ=...". However, the syntax to specify the | |
57 | * options changes slightly. You must replace all ',' between options | |
58 | * with ' ' and all ':' with '=' and you must use | |
59 | * '1' in place of 'Y' and '0' in place of 'N'. | |
60 | * | |
61 | * Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0 | |
52759e6a | 62 | * max_ids=127 rescan=0 hdr_channel=0 shared_access=0 |
31481455 | 63 | * force_dma32=0" |
1da177e4 LT |
64 | * The other example: "modprobe gdth reserve_list=0,1,2,0,0,1,3,0 rescan=1". |
