#
#	INSTALL -- installation kernel.
#

include "arch/x68k/conf/std.x68k"

#options 	INCLUDE_CONFIG_FILE	# embed config file in kernel binary

#ident 		"INSTALL-$Revision: 1.124 $"

makeoptions	COPTS="-Os -fno-unwind-tables" # Optimise for space. Implies -O2

maxusers	4

## Enable the hooks used for initializing the memory-disk.
options 	MEMORY_DISK_HOOKS
options 	MEMORY_DISK_IS_ROOT	# Force root on memory-disk
options 	MEMORY_DISK_SERVER=0	# No user space hooks
options 	MEMORY_DISK_ROOT_SIZE=3600	# size of memory disk, in blocks
options 	MEMORY_DISK_RBFLAGS=RB_SINGLE	# boot in single-user mode

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


## Options for variants of the m68k MPU
## you must have at least the correct one; REQUIRED
options 	M68030
options 	M68040
options 	M68060
## If you want an optimized kernel for a specific processor, use either:
#makeoptions	CMACHFLAGS="-m68030"
#makeoptions	CMACHFLAGS="-m68040 -Wa,-m68030 -Wa,-m68851"
#makeoptions	CMACHFLAGS="-m68060 -Wa,-m68030 -Wa,-m68851"


#### System options specific to the x68k port

options 	EXTENDED_MEMORY		# support for >16MB memory
options 	FPU_EMULATE		# software fpu emulation for MC68030
#options 	JUPITER			# support for "Jupiter-X" accelerator
#options 	ZSCONSOLE,ZSCN_SPEED="9600"	# use serial console


#### 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 ?
#config		netbsd	root on sd0 type ffs

## RTC is offset from GMT; -540 means JST-9
options 	RTC_OFFSET=-540	# hardware clock is this many mins. west of GMT

## 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

## Loadable kernel module support

options 	USERCONF		# userconf(4) support
options 	PIPE_SOCKETPAIR		# smaller, but slower pipe(2)
#options 	SYSCTL_INCLUDE_DESCR	# Include sysctl descriptions in kernel

## NFS boot options; not supported currently: needs nfsboot program
#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(7): `ddb.onpanic'
#options 	PANICBUTTON		# interrupt switch invokes DDB

## 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.
## KGDB is not supported for now.
#options 	KGDB			# support for kernel gdb
#options 	KGDB_DEV=0xc00		# kgdb device number
#options 	KGDB_DEVRATE=9600	# 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

## `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.

include 	"conf/compat_netbsd30.config"

#options 	COMPAT_AOUT_M68K # compatibility with NetBSD/m68k a.out

options 	INET6		# IPV6
#options 	IPSEC		# IP security
#options 	IPSEC_DEBUG	# debug for IP security
