50
51 ## Root device configuration: change the ?'s if you are going to use a
52 ## nonstandard root partition (other than where the kernel is booted from)
53 ## and/or nonstandard root type (not ffs or nfs). Normally this can be
54 ## automagically determined at boot time.
55
56 config netbsd root on ? type ?
57
58 ## System call tracing (see ktrace(1)).
59 #options KTRACE
60
61 ## Collect statistics on kernel malloc's and free's. This does have a
62 ## significant performance hit on slower machines, so it is intended for
63 ## diagnostic use only.
64 #options KMEMSTATS
65
66 ## System V compatible IPC subsystem. (msgctl(2), semctl(2), and shmctl(2))
67 #options SYSVMSG # System V message queues
68 #options SYSVSEM # System V semaphores

76 options NFS_BOOT_BOOTPARAM
77 #options NFS_BOOT_BOOTP
78 #options NFS_BOOT_DHCP
79
80 #### Debugging options
81
82 ## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
83 ## serial console break or keyboard reset, where the PROM would normally
84 ## intercept. DDB_HISTORY_SIZE adds up/down arrow command history.
85 #options DDB # kernel dynamic debugger
86 #options DDB_HISTORY_SIZE=100 # enable history editing in DDB
87 #options DDB_ONPANIC=1 # see also sysctl(8): `ddb.onpanic'
88
89 ## You may also use gdb, on another computer connected to this machine over
90 ## a serial port. Both KGDBDEV and KGDBRATE should be specified; KGDBDEV is
91 ## a dev_t encoded device number of the serial port to use.
92 ## (0xc01 = ttya, 0xc02 = ttyb.)
93 #options KGDB # support for kernel gdb
94 #options KGDBDEV=0xc01 # kgdb device number (this sample is `ttyb')
95 #options KGDBRATE=38400 # baud rate
96

98 ## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file),
99 ## such that gdb(1) can be used on a kernel coredump.
100
101 #makeoptions DEBUG="-g"
102
103
104 ## Adds code to the kernel that does internal consistency checks, and will
105 ## cause the kernel to panic if corruption of internal data structures
106 ## is detected.
107 #options DIAGNOSTIC # extra kernel sanity checking

114
115 ## Make SCSI error messages more verbose when explaining their meanings.
116 #options SCSIVERBOSE
117
118 ## `INSECURE' turns off the kernel security level (securelevel = 0 always).
119 ## This allows writing to /dev/mem, loading kernel modules while multi-user,
120 ## and other insecurities good only for development work. Do not use this
121 ## option on a production machine.
122 options INSECURE
123

125 ## `xconsole' therefore does not need setuid root with this option enabled.
126 #options UCONSOLE
127
128 ## `FDSCRIPTS' allows non-readable but executable scripts by providing a
129 ## pre-opened opaque file to the script interpreter. `SETUIDSCRIPTS',
130 ## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
131 ## opaque file mechanism. Perl calls this "secure setuid scripts."

328 ## 0x02 Use DMA completion interrupts
329 ## 0x04 Allow disconnect/reselect

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