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 26#options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28#ident "GENERIC-$Revision: 1.181 $" 29 30makeoptions COPTS="-Os" # bootloader has size limit (~2MB) 31 32# Machines to be supported by this kernel 33options FPU_EMULATE 34options HAVECACHE # Sun3/260 VAC 35 36# Needs to be set per system. i.e change these as you see fit 37maxusers 4 38 39# Standard system options 40options KTRACE # system call tracing 41options SYSVMSG # System V message queues 42options SYSVSEM # System V semaphores 43options SYSVSHM # System V shared memory 44 45#options MODULAR # new style module(7) framework 46#options MODULAR_DEFAULT_AUTOLOAD 47 48#options INSECURE # disable kernel security level 49#options USERCONF # userconf(4) support 50options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 51#options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 52 53# Alternate buffer queue strategies for better responsiveness under high 54# disk I/O load. 55#options BUFQ_READPRIO 56#options BUFQ_PRIOCSCAN 57 58# Which kernel debugger?
