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.

159 ## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
160 ## This driver has several flags which may be enabled using
161 ## the "flags" directive. Valid flags are:
162 ##
163 ## 0x0ff Set (1<<target) to disable parity checking
164 ## 0x100 Set this bit to disable DMA interrupts (poll)
165 ## 0x200 Set this bit to disable DMA entirely (use PIO)
166 ##
167 ## For example: "flags 0x10f" would disable DMA interrupts,
168 ## and disable parity for targets 0-3
169
170 sc0 at mbmem0 addr 0x80000 ipl 2 flags 0xff
171 sc0 at vme0 addr 0x200000 irq 2 vect 0x40 flags 0xff
172 sc1 at mbmem0 addr 0x84000 ipl 2 flags 0xff
173
174 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
175 ## This driver has several flags which may be enabled by OR'ing
176 ## the values and using the "flags" directive.
177 ## Valid flags are:
178 ##
179 ## 0x01 Use DMA (may be polled)
180 ## 0x02 Use DMA completion interrupts
181 ## 0x04 Allow disconnect/reselect
182 ##
183 ## E.g. the following would enable DMA, interrupts, and reselect:
184 ## si0 at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
185 ##
186 ## By default, DMA is enabled in the driver.
