14# Options for variants of the Sun SPARC architecure.
15# We currently support three architecture types; at least one is required.
16options 	SUN4U		# sun4u - UltraSPARC
17#options 	BLINK		# blink the system LED
18
19## System options specific to the sparc machine type
20
21## Use a faster console than the PROM's slow drawing routines.  Not needed
22## for headless (no framebuffer) machines.
23# XXX borken on sparc64
24#options 	RASTERCONSOLE		# fast rasterop console
25#options 	FONT_GALLANT12x22	# the console font
26#options 	FONT_BOLD8x16		# a somewhat smaller font
27
28#### System options that are the same for all ports
29
30## Root device configuration: change the ?'s if you are going to use a
31## nonstandard root partition (other than where the kernel is booted from)
32## and/or nonstandard root type (not ffs or nfs).  Normally this can be
33## automagically determined at boot time.

38#options 	UVM_PAGE_TRKOWN
39#options 	UVMHIST
40#options 	UVMHIST_PRINT	# Loud!
41
42## System call tracing (see ktrace(1)).
43options 	KTRACE
44
45## Collect statistics on kernel malloc's and free's.  This does have a
46## significant performance hit on slower machines, so it is intended for
47## diagnostic use only.
48#options 	KMEMSTATS
49
50## System V compatible IPC subsystem.  (msgctl(2), semctl(2), and shmctl(2))
51options 	SYSVMSG		# System V message queues

56## Loadable kernel module support; still under development.

67#### Debugging options
68
69## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
70## serial console break or keyboard reset, where the PROM would normally
71## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.
72# we enable DDB in GENERIC for now.
73options 	DDB			# kernel dynamic debugger
74options 	DDB_HISTORY_SIZE=100	# enable history editing in DDB
75#options 	DDB_ONPANIC		# see also sysctl(8): `ddb.onpanic'
76
77## You may also use gdb, on another computer connected to this machine over
78## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;
79## KGDB_DEV is a dev_t encoded device number of the serial port to use.
80## (0xc01 = ttya, 0xc02 = ttyb.)
81#options 	KGDB			# support for kernel gdb
82#options 	KGDB_DEV=0xc01		# kgdb device number (this is `ttyb')
83#options 	KGDB_DEVRATE=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

105#options 	PCI_CONFIG_DUMP	# verbosely dump PCI config space
106
107## `INSECURE' turns off the kernel security level (securelevel = 0 always).
108## This allows writing to /dev/mem, loading kernel modules while multi-user,
109## and other insecurities good only for development work.  Do not use this
110## option on a production machine.
111#options 	INSECURE
112
113## Allow non-root users to grab /dev/console with programs such as xconsole.
114## `xconsole' therefore does not need setuid root with this option enabled.
115#options 	UCONSOLE
116
117## `FDSCRIPTS' allows non-readable but executable scripts by providing a
118## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
119## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
120## opaque file mechanism.  Perl calls this "secure setuid scripts."

125## Options for compatibility with previous releases foreign system binaries.
