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.

152## PAL+logic-based "Sun SCSI 2" Multibus/VME SCSI controller.
153## This driver has several flags which may be enabled using
154## the "flags" directive.  Valid flags are:
155##
156## 0x0ff		Set (1<<target) to disable parity checking
157## 0x100		Set this bit to disable DMA interrupts (poll)
158## 0x200		Set this bit to disable DMA entirely (use PIO)
159##
160## For example: "flags 0x10f" would disable DMA interrupts,
161## and disable parity for targets 0-3

166
167## NCR5380-based "Sun SCSI 3" VME SCSI controller.
168## This driver has several flags which may be enabled by OR'ing
169## the values and using the "flags" directive.
170## Valid flags are:
171##
172##	0x01		Use DMA (may be polled)
173##	0x02		Use DMA completion interrupts
174##	0x04		Allow disconnect/reselect
175##
176## E.g. the following would enable DMA, interrupts, and reselect:
177## si0	at vme0 addr 0x200000 ipl 3 vect 0x40 flags 0x07
178##
179## By default, DMA is enabled in the driver.
