See options(4) for more detail. 8 9 10# Options for variants of the Sun SPARC architecure. 11# We currently support three architecture types; at least one is required. 12options SUN4 # sun4/100, sun4/200, sun4/300 13options SUN4C # sun4c - SS1, 1+, 2, ELC, SLC, IPC, IPX, etc. 14options SUN4M # sun4m - SS10, SS20, Classic, etc. 15 16#options MMU_3L # 3-level MMU on sun4/400; (incomplete) 17 18## System options specific to the sparc machine type 19 20# Blink the power LED on some machines to indicate the system load. 21#options BLINK 22 23## Use a faster console than the PROM's slow drawing routines. Not needed 24## for headless (no framebuffer) machines. 25options RASTERCONSOLE # fast rasterop console 26 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 35config netbsd root on ? type ? 36 37## System call tracing (see ktrace(1)). 38options KTRACE 39 40## Collect statistics on kernel malloc's and free's. This does have a 41## significant performance hit on slower machines, so it is intended for 42## diagnostic use only. 43#options KMEMSTATS 44 45## System V compatible IPC subsystem.

DDB_HISTORY_SIZE adds up/down arrow command history. 60#options DDB # kernel dynamic debugger 61#options DDB_HISTORY_SIZE=100 # enable history editing in DDB 62#options DDB_ONPANIC # see also sysctl(8): `ddb.onpanic' 63 64## You may also use gdb, on another computer connected to this machine over 65## a serial port. Both KGDBDEV and KGDBRATE should be specified; KGDBDEV is 66## a dev_t encoded device number of the serial port to use. 67## (0xc01 = ttya, 0xc02 = ttyb.) 68#options KGDB # support for kernel gdb 69#options KGDBDEV=0xc01 # kgdb device number (this sample is `ttyb') 70#options KGDBRATE=38400 # baud rate 71 72 73## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file), 74## such that gdb(1) can be used on a kernel coredump. 75 76#makeoptions DEBUG="-g" 77 78 79## Adds code to the kernel that does internal consistency checks, and will 80## cause the kernel to panic if corruption of internal data structures 81## is detected. 82#options DIAGNOSTIC # extra kernel sanity checking 83 84## Enable (possibly expensive) debugging code that may also display messages 85## on the system console 86#options DEBUG 87 88## Make SCSI error messages more verbose when explaining their meanings. 89options SCSIVERBOSE 90 91## `INSECURE' turns off the kernel security level (securelevel = 0 always). 92## This allows writing to /dev/mem, loading kernel modules while multi-user, 93## and other insecurities good only for development work. Do not use this 94## option on a production machine. 95#options INSECURE 96 97## Allow non-root users to grab /dev/console with programs such as xconsole. 98## `xconsole' therefore does not need setuid root with this option enabled. 99#options UCONSOLE 100 101## `FDSCRIPTS' allows non-readable but executable scripts by providing a 102## pre-opened opaque file to the script interpreter. `SETUIDSCRIPTS', 103## which implies FDSCRIPTS, allows scripts to be set-user-id using the same 104## opaque file mechanism. Perl calls this "secure setuid scripts." 105 106#options FDSCRIPTS 107#options SETUIDSCRIPTS 108 109## Options for compatibility with previous releases foreign system binaries. 110## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up 111## additional user-level utilities or system configuration files.
