301 | /* All GDT Disk Array Controllers are fully supported by this driver. | |
302 | * This includes the PCI/EISA/ISA SCSI Disk Array Controllers and the | |
303 | * PCI Fibre Channel Disk Array Controllers. See gdth.h for a complete | |
304 | * list of all controller types. | |
305 | * | |
306 | * If you have one or more GDT3000/3020 EISA controllers with | |
307 | * controller BIOS disabled, you have to set the IRQ values with the | |
308 | * command line option "gdth=irq1,irq2,...", where the irq1,irq2,... are | |
309 | * the IRQ values for the EISA controllers. | |
310 | * | |
311 | * After the optional list of IRQ values, other possible | |
312 | * command line options are: | |
313 | * disable:Y disable driver | |
314 | * disable:N enable driver | |
315 | * reserve_mode:0 reserve no drives for the raw service | |
316 | * reserve_mode:1 reserve all not init., removable drives | |
317 | * reserve_mode:2 reserve all not init. drives | |
318 | * reserve_list:h,b,t,l,h,b,t,l,... reserve particular drive(s) with | |
319 | * h- controller no., b- channel no., | |
320 | * t- target ID, l- LUN | |
321 | * reverse_scan:Y reverse scan order for PCI controllers | |
322 | * reverse_scan:N scan PCI controllers like BIOS | |
323 | * max_ids:x x - target ID count per channel (1..MAXID) | |
324 | * rescan:Y rescan all channels/IDs | |
325 | * rescan:N use all devices found until now | |
326 | * virt_ctr:Y map every channel to a virtual controller | |
327 | * virt_ctr:N use multi channel support | |
328 | * hdr_channel:x x - number of virtual bus for host drives | |
329 | * shared_access:Y disable driver reserve/release protocol to | |
330 | * access a shared resource from several nodes, | |
331 | * appropiate controller firmware required | |
332 | * shared_access:N enable driver reserve/release protocol | |
333 | * probe_eisa_isa:Y scan for EISA/ISA controllers | |
334 | * probe_eisa_isa:N do not scan for EISA/ISA controllers | |
335 | * force_dma32:Y use only 32 bit DMA mode | |
336 | * force_dma32:N use 64 bit DMA mode, if supported | |
337 | * | |
338 | * The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N, | |
339 | * max_ids:127,rescan:N,virt_ctr:N,hdr_channel:0, | |
340 | * shared_access:Y,probe_eisa_isa:N,force_dma32:N". | |
341 | * Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y". | |
342 | * | |
343 | * When loading the gdth driver as a module, the same options are available. | |
344 | * You can set the IRQs with "IRQ=...". However, the syntax to specify the | |
345 | * options changes slightly. You must replace all ',' between options | |
346 | * with ' ' and all ':' with '=' and you must use | |
347 | * '1' in place of 'Y' and '0' in place of 'N'. | |
348 | * | |
349 | * Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0 | |
350 | * max_ids=127 rescan=0 virt_ctr=0 hdr_channel=0 shared_access=0 | |
351 | * probe_eisa_isa=0 force_dma32=0" | |
