14 # Options for variants of the Sun SPARC architecure.
15 # We currently support three architecture types; at least one is required.
16 options 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.
34
35 config netbsd root on ? type ?
36
37 ## UVM options.
38 #options UVM_PAGE_TRKOWN
39 #options UVMHIST
40 #options UVMHIST_PRINT # Loud!
41
42 ## System call tracing (see ktrace(1)).
43 options 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))
51 options SYSVMSG # System V message queues
52 options SYSVSEM # System V semaphores
53 options SYSVSHM # System V shared memory
54 #options SHMMAXPGS=1024 # 1024 pages is the default
55
56 ## Loadable kernel module support; still under development.
57 options LKM
58
59 #options USERCONF # userconf(4) support
60 #options PIPE_SOCKETPAIR # smaller, but slower pipe(2)
61
62 ## NFS boot options; default on sparc is the bootparam protocol
63 options NFS_BOOT_BOOTPARAM
64 #options NFS_BOOT_BOOTP
65 #options NFS_BOOT_DHCP
66
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.
73 options DDB # kernel dynamic debugger
74 options 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
100
101 ## Make SCSI error messages more verbose when explaining their meanings.
102 options SCSIVERBOSE
103 options PCIVERBOSE
104 options MIIVERBOSE # verbose PHY autoconfig messages
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."
121
122 #options FDSCRIPTS
123 #options SETUIDSCRIPTS
124
125 ## Options for compatibility with previous releases foreign system binaries.
126 ## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up
127 ## additional user-level utilities or system configuration files. See
128 ## compat_sunos(8) and compat_svr4(8).
