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"
352 * The other example: "modprobe gdth reserve_list=0,1,2,0,0,1,3,0 rescan=1".

355 /* The meaning of the Scsi_Pointer members in this driver is as follows:

357 * this_residual: Command priority
358 * buffer: phys. DMA sense buffer
359 * dma_handle: phys. DMA buffer (kernel >= 2.4.0)
360 * buffers_residual: Timeout value
361 * Status: Command status (gdth_do_cmd()), DMA mem. mappings
362 * Message: Additional info (gdth_do_cmd()), DMA direction
