1# $NetBSD: GENERIC,v 1.184 2020/08/10 06:32:58 rin 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 26#options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28#ident "GENERIC-$Revision: 1.184 $" 29 30makeoptions COPTS="-Os -fno-unwind-tables -fno-omit-frame-pointer" 31 # Bootloader has size limit (~2MB). -fno-omit-frame-pointer is 32 # necessary for backtraces in DDB. 33 34# Machines to be supported by this kernel 35options FPU_EMULATE 36options HAVECACHE # Sun3/260 VAC 37 38# Needs to be set per system. i.e change these as you see fit 39maxusers 4 40 41# Standard system options 42options KTRACE # system call tracing 43options SYSVMSG # System V message queues 44options SYSVSEM # System V semaphores 45options SYSVSHM # System V shared memory 46 47#options MODULAR # new style module(7) framework 48#options MODULAR_DEFAULT_AUTOLOAD 49 50#options INSECURE # disable kernel security level 51#options USERCONF # userconf(4) support 52options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 53#options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 54 55# Alternate buffer queue strategies for better responsiveness under high 56# disk I/O load. 57#options BUFQ_READPRIO 58#options BUFQ_PRIOCSCAN 59 60# Which kernel debugger?
