# GENERIC machine description file
# 
# This machine description file is used to generate the default NetBSD
# kernel.  The generic kernel does not include all options, subsystems
# and device drivers, but should be useful for most applications.
#
# The machine description file can be customised for your specific
# machine to reduce the kernel size and improve its performance.
#
# For further information on compiling NetBSD kernels, see the config(8)
# man page.
#
# For further information on hardware support for this architecture, see
# the intro(4) man page.  For further information about kernel options
# for this architecture, see the options(4) man page.  For an explanation
# of each device driver in this file see the section 4 man page for the
# device.

# Supports Sun2 (2/120, 2/170, 2/50, ...)
# Supports root on: ie0, sd*, ...

#### Disk controllers and disks.

## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
## This driver has several flags which may be enabled using
## the "flags" directive.  Valid flags are:
##
## 0x0ff		Set (1<<target) to disable parity checking
## 0x100		Set this bit to disable DMA interrupts (poll)
## 0x200		Set this bit to disable DMA entirely (use PIO)
##
## For example: "flags 0x10f" would disable DMA interrupts,
## and disable parity for targets 0-3

sc0	at mbmem0 addr 0x80000 ipl 2 flags 0xff
sc0	at vme0 addr 0x200000 irq 2 vect 0x40 flags 0xff
sc1	at mbmem0 addr 0x84000 ipl 2 flags 0xff

## NCR5380-based "Sun SCSI 3" VME SCSI controller.
## This driver has several flags which may be enabled by OR'ing
## the values and using the "flags" directive.
## Valid flags are:
##
##	0x01		Use DMA (may be polled)
##	0x02		Use DMA completion interrupts
##	0x04		Allow disconnect/reselect
##
## E.g. the following would enable DMA, interrupts, and reselect:
## si0	at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
##
## By default, DMA is enabled in the driver.

si0	at vme0 addr 0x200000 irq 2 vect 0x40

## These entries find devices on all SCSI busses and assign
## unit numbers dynamically.
