# $NetBSD: OLPC,v 1.884 2008/03/18 20:48:42 cube Exp $ # # OLPC machine description file # # This machine description file is used to generate the default NetBSD # kernel. The generic kernel does not include all options, subsystems # and device drivers, but should be useful for most applications. # # The machine description file can be customised for your specific # machine to reduce the kernel size and improve its performance. # # For further information on compiling NetBSD kernels, see the config(8) # man page. # # For further information on hardware support for this architecture, see # the intro(4) man page. For further information about kernel options # for this architecture, see the options(4) man page. For an explanation # of each device driver in this file see the section 4 man page for the # device. include "arch/i386/conf/std.i386" #ident "OLPC-$Revision: 1.884 $" maxusers 32 # estimated number of users makeoptions CPUFLAGS="-march=k6-3 -mtune=k6-3" # For now, OLPC has Geode LX # This is where Open Firmware supposedly wants to load the kernel: makeoptions TEXTADDR=0x400000 # CPU-related options. options VM86 # virtual 8086 emulation options MTRR # memory-type range register syscall support options OLPC # General OLPC flag (maybe make generic!) # The following options override the memory sizes passed in from the boot # block.
