1# $NetBSD: GENERIC,v 1.103 2004/06/18 15:04:06 christos Exp $ 2# 3# GENERIC machine description file 4# 5# This machine description file is used to generate the default NetBSD 6# kernel. The generic kernel does not include all options, subsystems 7# and device drivers, but should be useful for most applications. 8# 9# The machine description file can be customised for your specific 10# machine to reduce the kernel size and improve its performance. 11# 12# For further information on compiling NetBSD kernels, see the config(8) 13# man page. 14# 15# For further information on hardware support for this architecture, see 16# the intro(4) man page. For further information about kernel options 17# for this architecture, see the options(4) man page. For an explanation 18# of each device driver in this file see the section 4 man page for the 19# device. 20 21# Supports Sun3 (3/50, 3/60, 3/110, 3/160, 3/260, 3/E) 22# Supports root on: ie0, le0, sd*, ... 23 24include "arch/sun3/conf/std.sun3" 25 26options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28#ident "GENERIC-$Revision: 1.103 $" 29 30# Machines to be supported by this kernel 31options FPU_EMULATE 32options HAVECACHE # Sun3/260 VAC 33 34# Needs to be set per system. i.e change these as you see fit 35maxusers 4 36 37# Standard system options 38options KTRACE # system call tracing 39options SYSTRACE # system call vetting via systrace(1) 40options SYSVMSG # System V message queues 41options SYSVSEM # System V semaphores 42#options SEMMNI=10 # number of semaphore identifiers 43#options SEMMNS=60 # number of semaphores in system 44#options SEMUME=10 # max number of undo entries per process 45#options SEMMNU=30 # number of undo structures in system 46options SYSVSHM # System V shared memory 47#options SHMMAXPGS=1024 # 1024 pages is the default 48options LKM # loadable kernel modules 49#options INSECURE # disable kernel security level 50options USERCONF # userconf(4) support 51#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 52 53# Enable experimental buffer queue strategy for better responsiveness under 54# high disk I/O load.
