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 21include "arch/mac68k/conf/std.mac68k" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.239 $" 26 27makeoptions COPTS="-O2 -fno-reorder-blocks -fno-omit-frame-pointer" 28 # See share/mk/sys.mk. -fno-omit-frame-pointer is necessary for 29 # backtraces in DDB. 30 31maxusers 16 # estimated number of users 32 33# CPU support.
