| /* All GDT Disk Array Controllers are fully supported by this driver. |
| * This includes the PCI/EISA/ISA SCSI Disk Array Controllers and the |
| * PCI Fibre Channel Disk Array Controllers. See gdth.h for a complete |
| * list of all controller types. |
| * |
| * If you have one or more GDT3000/3020 EISA controllers with |
| * controller BIOS disabled, you have to set the IRQ values with the |
| * command line option "gdth=irq1,irq2,...", where the irq1,irq2,... are |
| * the IRQ values for the EISA controllers. |
| * |
| * After the optional list of IRQ values, other possible |
| * command line options are: |
| * disable:Y disable driver |
| * disable:N enable driver |
| * reserve_mode:0 reserve no drives for the raw service |
| * reserve_mode:1 reserve all not init., removable drives |
| * reserve_mode:2 reserve all not init. drives |
| * reserve_list:h,b,t,l,h,b,t,l,... reserve particular drive(s) with |
| * h- controller no., b- channel no., |
| * t- target ID, l- LUN |
| * reverse_scan:Y reverse scan order for PCI controllers |
| * reverse_scan:N scan PCI controllers like BIOS |
| * max_ids:x x - target ID count per channel (1..MAXID) |
| * rescan:Y rescan all channels/IDs |
| * rescan:N use all devices found until now |
| * virt_ctr:Y map every channel to a virtual controller |
| * virt_ctr:N use multi channel support |
| * hdr_channel:x x - number of virtual bus for host drives |
| * shared_access:Y disable driver reserve/release protocol to |
| * access a shared resource from several nodes, |
| * appropriate controller firmware required |
| * shared_access:N enable driver reserve/release protocol |
| * probe_eisa_isa:Y scan for EISA/ISA controllers |
| * probe_eisa_isa:N do not scan for EISA/ISA controllers |
| * force_dma32:Y use only 32 bit DMA mode |
| * force_dma32:N use 64 bit DMA mode, if supported |
| * |
| * The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N, |
| * max_ids:127,rescan:N,virt_ctr:N,hdr_channel:0, |
| * shared_access:Y,probe_eisa_isa:N,force_dma32:N". |
| * Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y". |
| * |
| * When loading the gdth driver as a module, the same options are available. |
| * You can set the IRQs with "IRQ=...". However, the syntax to specify the |
| * options changes slightly. You must replace all ',' between options |
| * with ' ' and all ':' with '=' and you must use |
| * '1' in place of 'Y' and '0' in place of 'N'. |
| * |
| * Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0 |
| * max_ids=127 rescan=0 virt_ctr=0 hdr_channel=0 shared_access=0 |
| * probe_eisa_isa=0 force_dma32=0" |
| * The other example: "modprobe gdth reserve_list=0,1,2,0,0,1,3,0 rescan=1". |

| |
| /* The meaning of the Scsi_Pointer members in this driver is as follows: |
| * ptr: Chaining |
| * this_residual: Command priority |
| * buffer: phys. DMA sense buffer |
| * dma_handle: phys. DMA buffer (kernel >= 2.4.0) |
| * buffers_residual: Timeout value |
| * Status: Command status (gdth_do_cmd()), DMA mem. mappings |
| * Message: Additional info (gdth_do_cmd()), DMA direction |
| * have_data_in: Flag for gdth_wait_completion() |
| * sent_command: Opcode special command |
| * phase: Service/parameter/return code special command |
