1# $NetBSD: VR41XX,v 1.16 2003/12/27 07:29:56 shin 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 21include "arch/hpcmips/conf/std.hpcmips" 22include "arch/hpcmips/conf/std.hpcmips.vr41" 23#ident "GENERIC-$Revision: 1.16 $" 24 25#options INCLUDE_CONFIG_FILE # embed config file in kernel binary 26 27maxusers 16 28 29# Support for specific models of H/PC MIPS 30options VR4102 # NEC VR4102 31options VR4111 # NEC VR4111 32options VR4121 # NEC VR4121 33options VR4122 # NEC VR4122 34options VR4131 # NEC VR4131 35 36# Standard system options 37options DDB # in-kernel debugger 38#options DDB_ONPANIC=0 # don't enter debugger on panic 39#options KGDB # remote debugger 40#options DIAGNOSTIC # extra kernel debugging checks 41#options DEBUG # extra kernel debugging support 42options KTRACE # system call tracing support 43options MSGBUFSIZE=8192 # dmesg buffer size 44options USERCONF # userconf(4) support 45#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 46options KLOADER_KERNEL_PATH="\"/netbsd\"" 47options KLOADER_DEBUG 48 49## UVM options. 50#options UVM_PAGE_TRKOWN 51#options UVMHIST 52#options UVMHIST_PRINT # Loud! 53 54#options SCSIVERBOSE # human readable SCSI error messages 55#options PCMCIAVERBOSE # verbose PCMCIA configuration messages 56 57#options RTC_OFFSET=0 # hardware clock is this many mins. west of GMT 58#options RTC_OFFSET=-540 # JST-9 59#options RTC_OFFSET=480 # PST8 60 # In NO RTC_OFFSET , inherit RTC_OFFSET 61 # from Windows CE. 62options NTP # network time protocol 63 64#options WINCE_DEFAULT_SETTING # Debugging use 65 66#options SYSCALL_DEBUG # for debug 67#options HPCMIPS_L1CACHE_DISABLE # disable L1 cache for debug 68 69# Filesystem options 70file-system FFS # fast filesystem with user and group quotas 71file-system MFS # memory-based filesystem 72file-system NFS # Sun NFS-compatible filesystem (client) 73#file-system LFS # Log-based filesystem (still experimental) 74file-system CD9660 # ISO 9660 + Rock Ridge file system 75file-system MSDOSFS # MS-DOS file system 76#file-system FDESC # /dev/fd 77file-system KERNFS # /kern (kernel informational filesystem) 78#file-system NULLFS # loopback file system 79#file-system OVERLAY # overlay file system 80#file-system PORTAL # portal filesystem (still experimental) 81file-system PROCFS # /proc 82#file-system UMAPFS # NULLFS + uid and gid remapping 83file-system UNION 84 85#options NFSSERVER # Sun NFS-compatible filesystem (server) 86options SOFTDEP # FFS soft updates support. 87#options QUOTA # UFS quotas 88options VNODE_OP_NOINLINE # don't inline vnode op calls 89 90# Networking options 91#options GATEWAY # IP packet forwarding 92options INET # IP + ICMP + TCP + UDP 93options INET6 # IPV6 94#options IPSEC # IP security 95#options IPSEC_ESP # IP security (encryption part; define w/ IPSEC) 96#options IPSEC_DEBUG # debug for IP security 97#options MROUTING # Multicast routing support 98#options ISO # OSI networking 99#options TPIP # TPIP 100#options EON # OSI tunneling over IP 101#options CCITT,LLC,HDLC # X.25 102 103# NetBSD backwards compatibility 104options COMPAT_43 105 106options NFS_BOOT_DHCP 107 108config netbsd root on ? type ? 109 110# compile options 111#makeoptions DEFGP="-G 8" 112 113# WS console uses SUN or VT100 terminal emulation 114options WSEMUL_VT100 115#options WSDISPLAY_DEFAULTSCREENS=4 116#options FONT_VT220L8x8 117options FONT_VT220L8x10 118# compatibility to other console drivers 119options WSDISPLAY_COMPAT_PCVT # emulate some ioctls 120options WSDISPLAY_COMPAT_SYSCONS # emulate some ioctls 121options WSDISPLAY_COMPAT_USL # VT handling 122options WSDISPLAY_COMPAT_RAWKBD # can get raw scancodes 123# 124# Hpckbd will set key board layout appropriately.
