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 Sun2 (2/120, 2/170, 2/50, ...) 22# Supports root on: ie0, sd*, ... 23 24include "arch/sun2/conf/std.sun2" 25 26options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28#ident "GENERIC-$Revision: 1.89 $" 29 30makeoptions COPTS="-Os" # optimize for size 31 32# Machines to be supported by this kernel 33#options FPU_EMULATE 34 35# Needs to be set per system. i.e change these as you see fit 36maxusers 4 37 38# Standard system options 39options KTRACE # system call tracing 40options SYSVMSG # System V message queues 41options SYSVSEM # System V semaphores 42options SYSVSHM # System V shared memory 43#options INSECURE # disable kernel security level 44#options USERCONF # userconf(4) support 45#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 46options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 47 48# Enable experimental buffer queue strategy for better responsiveness under 49# high disk I/O load.
