# 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 architecture.
# 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 SUN4D # sun4d - SS1000, SC2000
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
options FONT_GALLANT12x22 # the console font
options FONT_BOLD8x16 # a somewhat smaller font
#### 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
## System V compatible IPC subsystem. (msgctl(2), semctl(2), and shmctl(2))
options SYSVMSG # System V message queues
options SYSVSEM # System V semaphores
options SYSVSHM # System V shared memory
options MODULAR # new style module(7) framework
options MODULAR_DEFAULT_AUTOLOAD
options USERCONF # userconf(4) support
#options PIPE_SOCKETPAIR # smaller, but slower pipe(2)
options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel
# Alternate buffer queue strategies for better responsiveness under high
# disk I/O load.
#options BUFQ_READPRIO
options BUFQ_PRIOCSCAN
## 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(7): `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
#options LOCKDEBUG
#options SYSCALL_DEBUG
## Make SCSI error messages more verbose when explaining their meanings.
options SCSIVERBOSE
## `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
## `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, you may need to set up additional user-level
## utilities or system configuration files. See compat_sunos(8).

## 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.
