12 # Options for variants of the Sun SPARC architecure.
13 # We currently support three architecture types; at least one is required.
14 options SUN4 # sun4/100, sun4/200, sun4/300
15 options SUN4C # sun4c - SS1, 1+, 2, ELC, SLC, IPC, IPX, etc.
16 options 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.
27 options RASTERCONSOLE # fast rasterop console
28 options FONT_GALLANT12x22 # the console font
29 #options FONT_BOLD8x16 # a somewhat smaller font
30 options RASTERCONSOLE_FGCOL=WSCOL_BLACK
31 options RASTERCONSOLE_BGCOL=WSCOL_WHITE
32
33 #### System options that are the same for all ports
34
35 ## Root device configuration: change the ?'s if you are going to use a
36 ## nonstandard root partition (other than where the kernel is booted from)
37 ## and/or nonstandard root type (not ffs or nfs). Normally this can be
38 ## automagically determined at boot time.
39
40 config netbsd root on ? type ?
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 ## NFS boot options; default on sparc is the bootparam protocol
60 options NFS_BOOT_BOOTPARAM
61 #options NFS_BOOT_BOOTP
62 #options NFS_BOOT_DHCP
63
64 #### Debugging options
65
66 ## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
67 ## serial console break or keyboard reset, where the PROM would normally
68 ## intercept. DDB_HISTORY_SIZE adds up/down arrow command history.
69 #options DDB # kernel dynamic debugger
70 #options DDB_HISTORY_SIZE=100 # enable history editing in DDB
71 #options DDB_ONPANIC=1 # see also sysctl(8): `ddb.onpanic'
72
73 ## You may also use gdb, on another computer connected to this machine over
74 ## a serial port. Both KGDBDEV and KGDBRATE should be specified; KGDBDEV is
75 ## a dev_t encoded device number of the serial port to use.
76 ## (0xc01 = ttya, 0xc02 = ttyb.)
77 #options KGDB # support for kernel gdb
78 #options KGDBDEV=0xc01 # kgdb device number (this sample is `ttyb')
79 #options KGDBRATE=38400 # baud rate
80
81
82 ## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file),
83 ## such that gdb(1) can be used on a kernel coredump.
84
85 #makeoptions DEBUG="-g"
86
87
88 ## Adds code to the kernel that does internal consistency checks, and will
89 ## cause the kernel to panic if corruption of internal data structures
90 ## is detected.
91 #options DIAGNOSTIC # extra kernel sanity checking
92
93 ## Enable (possibly expensive) debugging code that may also display messages
94 ## on the system console
95 #options DEBUG
96
97 ## Make SCSI error messages more verbose when explaining their meanings.
98 options SCSIVERBOSE
99
100 ## `INSECURE' turns off the kernel security level (securelevel = 0 always).
101 ## This allows writing to /dev/mem, loading kernel modules while multi-user,
102 ## and other insecurities good only for development work. Do not use this
103 ## option on a production machine.
104 #options INSECURE
105
106 ## Allow non-root users to grab /dev/console with programs such as xconsole.
107 ## `xconsole' therefore does not need setuid root with this option enabled.
108 #options UCONSOLE
109
110 ## `FDSCRIPTS' allows non-readable but executable scripts by providing a
111 ## pre-opened opaque file to the script interpreter. `SETUIDSCRIPTS',
112 ## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
113 ## opaque file mechanism. Perl calls this "secure setuid scripts."
114
115 #options FDSCRIPTS
116 #options SETUIDSCRIPTS
117
118 ## Options for compatibility with previous releases foreign system binaries.
119 ## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up
120 ## additional user-level utilities or system configuration files. See
121 ## compat_sunos(8) and compat_svr4(8).

324 ## NCR5380-based "Sun SCSI 3" VME SCSI controller.
325 ## This driver has several flags which may be enabled by OR'ing
326 ## the values and using the "flags" directive.
327 ## Valid flags are:
328 ##
329 ## 0x01 Use DMA (may be polled)
330 ## 0x02 Use DMA completion interrupts
331 ## 0x04 Allow disconnect/reselect
332 ##
333 ## E.g. the following would enable DMA, interrupts, and reselect:
334 ## si0 at vme0 addr 0x200000 irq 3 vect 0x40 flags 0x07

512 ## Sun "bwtwo" black and white framebuffer, found on sun4, sun4c, and sun4m
513 ## systems. If your sun4 system has a cgfour installed in the P4 slot,
514 ## the P4 entries for "bwtwo" will attach to the overlay plane of the
515 ## "cgfour".

558 ## like, though 256 is more or less the upper limit. Increasing this
559 ## number still requires you to run /dev/MAKEDEV to create the files
