11
12# Options for variants of the Sun SPARC architecure.
13# We currently support three architecture types; at least one is required.
14options 	SUN4		# sun4/100, sun4/200, sun4/300
15options 	SUN4C		# sun4c - SS1, 1+, 2, ELC, SLC, IPC, IPX, etc.
16options 	SUN4M		# sun4m - SS10, SS20, Classic, etc.
17
18#options 	SUN4_MMU3L	# 3-level MMU on sun4/400; (incomplete)
19
20## System options specific to the sparc machine type
21
22# Blink the power LED on some machines to indicate the system load.
23#options 	BLINK
24
25## Use a faster console than the PROM's slow drawing routines.  Not needed
26## for headless (no framebuffer) machines.
27options 	RASTERCONSOLE		# fast rasterop console
28options 	FONT_GALLANT12x22	# the console font
29#options 	FONT_BOLD8x16		# a somewhat smaller font
30## default console colors: black-on-white; this can be changed
31## using the following two options.
32#options 	RASTERCONSOLE_FGCOL=WSCOL_BLACK
33#options 	RASTERCONSOLE_BGCOL=WSCOL_WHITE
34
35#### System options that are the same for all ports
36
37## Root device configuration: change the ?'s if you are going to use a
38## nonstandard root partition (other than where the kernel is booted from)
39## and/or nonstandard root type (not ffs or nfs).  Normally this can be
40## automagically determined at boot time.
41
42config		netbsd	root on ? type ?
43
44## System call tracing (see ktrace(1)).
45options 	KTRACE
46
47## Collect statistics on kernel malloc's and free's.  This does have a
48## significant performance hit on slower machines, so it is intended for
49## diagnostic use only.
50#options 	KMEMSTATS
51
52## System V compatible IPC subsystem.  (msgctl(2), semctl(2), and shmctl(2))
53options 	SYSVMSG		# System V message queues
54options 	SYSVSEM		# System V semaphores
55options 	SYSVSHM		# System V shared memory
56#options 	SHMMAXPGS=1024	# 1024 pages is the default
57
58## Loadable kernel module support; still under development.
59options 	LKM
60
61## NFS boot options; default on sparc is the bootparam protocol
62options 	NFS_BOOT_BOOTPARAM
63#options 	NFS_BOOT_BOOTP
64#options 	NFS_BOOT_DHCP
65
66#### Debugging options
67
68## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
69## serial console break or keyboard reset, where the PROM would normally
70## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.
71#options 	DDB			# kernel dynamic debugger
72#options 	DDB_HISTORY_SIZE=100	# enable history editing in DDB
73#options 	DDB_ONPANIC=1		# see also sysctl(8): `ddb.onpanic'
74
75## You may also use gdb, on another computer connected to this machine over
76## a serial port.  Both KGDBDEV and KGDBRATE should be specified; KGDBDEV is
77## a dev_t encoded device number of the serial port to use, where the minor
78## device number encodes the PROM enumeration of the serial ports, i.e.:
79## 0xc00 = ttya, 0xc01 = ttyb, 0xc02 = ttyc, 0xc03 = ttyd.  (Note: ttyc and
80## ttyd are available only on some sun4 models)
81#options 	KGDB		# support for kernel gdb
82#options 	KGDBDEV=0xc01	# kgdb device number (this sample is `ttyb')
83#options 	KGDBRATE=38400	# baud rate
84
85
86## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file),
87## such that gdb(1) can be used on a kernel coredump.
88
89#makeoptions 	DEBUG="-g"
90
91
92## Adds code to the kernel that does internal consistency checks, and will
93## cause the kernel to panic if corruption of internal data structures
94## is detected.
95#options 	DIAGNOSTIC	# extra kernel sanity checking
96
97## Enable (possibly expensive) debugging code that may also display messages
98## on the system console
99#options 	DEBUG
100
101## Make SCSI error messages more verbose when explaining their meanings.
102options 	SCSIVERBOSE
103
104## `INSECURE' turns off the kernel security level (securelevel = 0 always).
105## This allows writing to /dev/mem, loading kernel modules while multi-user,
106## and other insecurities good only for development work.  Do not use this
107## option on a production machine.
108#options 	INSECURE
109
110## Allow non-root users to grab /dev/console with programs such as xconsole.
111## `xconsole' therefore does not need setuid root with this option enabled.
112#options 	UCONSOLE
113
114## `FDSCRIPTS' allows non-readable but executable scripts by providing a
115## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
116## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
117## opaque file mechanism.  Perl calls this "secure setuid scripts."
118
119#options 	FDSCRIPTS
120#options 	SETUIDSCRIPTS
121
122## Options for compatibility with previous releases foreign system binaries.
123## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up
124## additional user-level utilities or system configuration files. See
125## compat_sunos(8) and compat_svr4(8).

333## Valid flags are:

336##	0x02		Use DMA completion interrupts
337##	0x04		Allow disconnect/reselect
