3 # GENERIC machine description file
4 #
5 # This machine description file is used to generate the default NetBSD
6 # kernel. The generic kernel does not include all options, subsystems
7 # and device drivers, but should be useful for most applications.
8 #
9 # The machine description file can be customised for your specific
10 # machine to reduce the kernel size and improve its performance.
11 #
12 # For further information on compiling NetBSD kernels, see the config(8)
13 # man page.
14 #
15 # For further information on hardware support for this architecture, see
16 # the intro(4) man page. For further information about kernel options
17 # for this architecture, see the options(4) man page. For an explanation
18 # of each device driver in this file see the section 4 man page for the
19 # device.
21 # Supports Sun2 (2/120, 2/170, 2/50, ...)
22 # Supports root on: ie0, sd*, ...

177 #### Disk controllers and disks.
179 ## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
180 ## This driver has several flags which may be enabled using
181 ## the "flags" directive. Valid flags are:
182 ##
183 ## 0x0ff Set (1<<target) to disable parity checking
184 ## 0x100 Set this bit to disable DMA interrupts (poll)
185 ## 0x200 Set this bit to disable DMA entirely (use PIO)
186 ##
187 ## For example: "flags 0x10f" would disable DMA interrupts,
188 ## and disable parity for targets 0-3
190 sc0 at mbmem0 addr 0x80000 ipl 2 flags 0xff
191 sc0 at vme0 addr 0x200000 irq 2 vect 0x40 flags 0xff
192 sc1 at mbmem0 addr 0x84000 ipl 2 flags 0xff
194 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
195 ## This driver has several flags which may be enabled by OR'ing
196 ## the values and using the "flags" directive.
197 ## Valid flags are:
198 ##
199 ## 0x01 Use DMA (may be polled)
200 ## 0x02 Use DMA completion interrupts
201 ## 0x04 Allow disconnect/reselect
202 ##
203 ## E.g. the following would enable DMA, interrupts, and reselect:
204 ## si0 at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
205 ##
206 ## By default, DMA is enabled in the driver.
208 si0 at vme0 addr 0x200000 irq 2 vect 0x40
210 ## These entries find devices on all SCSI busses and assign
211 ## unit numbers dynamically.
