# 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.

## System kernel configuration.  See options(4) for more detail.


# Options for variants of the Sun SPARC architecure.
# We currently support three architecture types; at least one is required.
options 	SUN4		# sun4/100, sun4/200, sun4/300
options 	SUN4C		# sun4c - SS1, 1+, 2, ELC, SLC, IPC, IPX, etc.
options 	SUN4M		# sun4m - SS10, SS20, Classic, etc.

options 	SUN4_MMU3L	# sun4/400 3-level MMU

## System options specific to the sparc machine type

# Blink the power LED on some machines to indicate the system load.
#options 	BLINK

## Use a faster console than the PROM's slow drawing routines.  Not needed
## for headless (no framebuffer) machines.
options 	RASTERCONSOLE		# fast rasterop console
options 	FONT_GALLANT12x22	# the console font
#options 	FONT_BOLD8x16		# a somewhat smaller font
## default console colors: black-on-white; this can be changed
## using the following two options.
#options 	RASTERCONSOLE_FGCOL=WSCOL_BLACK
#options 	RASTERCONSOLE_BGCOL=WSCOL_WHITE

#### System options that are the same for all ports

## Root device configuration: change the ?'s if you are going to use a
## nonstandard root partition (other than where the kernel is booted from)
## and/or nonstandard root type (not ffs or nfs).  Normally this can be
## automagically determined at boot time.

config		netbsd	root on ? type ?

## System call tracing (see ktrace(1)).
options 	KTRACE
options 	SYSTRACE	# system call vetting via systrace(1)

## Collect statistics on kernel malloc's and free's.  This does have a
## significant performance hit on slower machines, so it is intended for
## diagnostic use only.
#options 	KMEMSTATS

## System V compatible IPC subsystem.  (msgctl(2), semctl(2), and shmctl(2))
options 	SYSVMSG		# System V message queues
options 	SYSVSEM		# System V semaphores
#options 	SEMMNI=10	# number of semaphore identifiers
#options 	SEMMNS=60	# number of semaphores in system
#options 	SEMUME=10	# max number of undo entries per process
#options 	SEMMNU=30	# number of undo structures in system
options 	SYSVSHM		# System V shared memory
#options 	SHMMAXPGS=1024	# 1024 pages is the default

## Loadable kernel module support; still under development.
options 	LKM

options 	USERCONF	# userconf(4) support
#options	PIPE_SOCKETPAIR	# smaller, but slower pipe(2)

# Enable experimental buffer queue strategy for better responsiveness under 
# high disk I/O load. Use it with caution - it's not proven to be stable yet.
#options 	NEW_BUFQ_STRATEGY

## NFS boot options; tries DHCP/BOOTP then BOOTPARAM
options 	NFS_BOOT_BOOTPARAM
#options 	NFS_BOOT_BOOTP
options 	NFS_BOOT_DHCP

#### Debugging options

## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
## serial console break or keyboard reset, where the PROM would normally
## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.
#options 	DDB			# kernel dynamic debugger
#options 	DDB_HISTORY_SIZE=100	# enable history editing in DDB
#options 	DDB_ONPANIC=1		# see also sysctl(8): `ddb.onpanic'

## You may also use gdb, on another computer connected to this machine over
## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;
## KGDB_DEV is a dev_t encoded device number of the serial port to use, where
## the minor device number encodes the PROM enumeration of the serial ports,
## i.e.:
## 0xc00 = ttya, 0xc01 = ttyb, 0xc02 = ttyc, 0xc03 = ttyd.
## (Note: ttyc and ttyd are available only on some sun4 models)
#options 	KGDB			# support for kernel gdb
#options 	KGDB_DEV=0xc01		# kgdb device number (this is `ttyb')
#options 	KGDB_DEVRATE=38400	# baud rate


## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file),
## such that gdb(1) can be used on a kernel coredump.

#makeoptions	DEBUG="-g"


## Adds code to the kernel that does internal consistency checks, and will
## cause the kernel to panic if corruption of internal data structures
## is detected.
#options 	DIAGNOSTIC	# extra kernel sanity checking

## Enable (possibly expensive) debugging code that may also display messages
## on the system console
#options 	DEBUG

## Make SCSI error messages more verbose when explaining their meanings.
options 	SCSIVERBOSE

options 	MIIVERBOSE	# verbose PHY autoconfig messages

## `INSECURE' turns off the kernel security level (securelevel = 0 always).
## This allows writing to /dev/mem, loading kernel modules while multi-user,
## and other insecurities good only for development work.  Do not use this
## option on a production machine.
#options 	INSECURE

## Allow non-root users to grab /dev/console with programs such as xconsole.
## `xconsole' therefore does not need setuid root with this option enabled.
#options 	UCONSOLE

## `FDSCRIPTS' allows non-readable but executable scripts by providing a
## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
## opaque file mechanism.  Perl calls this "secure setuid scripts."

#options 	FDSCRIPTS
#options 	SETUIDSCRIPTS

## Options for compatibility with previous releases foreign system binaries.
## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up
## additional user-level utilities or system configuration files. See
## compat_sunos(8) and compat_svr4(8).

## The following flags may be set for the NCR53c94 based esp driver:
##	bits 0-7:  disable disconnect/reselect for the corresponding target
##	bits 8-15: disable synchronous negotiation for target [bit-8]

## sun4/300, sun4c, sun4m on-board SCSI, and FSBE/S SBus SCSI cards.
## Both `dma' and `esp' are needed in all cases.
## Two kinds of additional SBus SCSI interfaces are available.  One uses
## "esp at sbus" like the sun4c on-board; the other uses "esp at dma".

## 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 irq 3 vect 0x40 flags 0x07
##
## By default, DMA is enabled in the driver.

si0	at vme0 addr 0x200000 irq 2 vect 0x40

## NCR5380-based "SCSI Weird" on-board SCSI interface found
## on sun4/100 systems.  The flags are the same as the "si"
## controller.  Note, while DMA is enabled by default, only
