1# $NetBSD: GENERIC,v 1.50 2024/01/29 18:27:14 christos 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/rs6000/conf/std.rs6000" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#makeoptions COPTS="-O2 -mno-powerpc -mno-power" # wheeee 26 27#ident "GENERIC-$Revision: 1.50 $" 28 29maxusers 32 30 31# Platform support 32 33options PIC_IOCC 34 35# Standard system options 36 37options RTC_OFFSET=0 # hardware clock is this many mins. west of GMT 38options NTP # NTP phase/frequency locked loop 39 40options KTRACE # system call tracing via ktrace(1) 41 42options SYSVMSG # System V-like message queues 43options SYSVSEM # System V-like semaphores 44#options SEMMNI=10 # number of semaphore identifiers 45#options SEMMNS=60 # number of semaphores in system 46#options SEMUME=10 # max number of undo entries per process 47#options SEMMNU=30 # number of undo structures in system 48options SYSVSHM # System V-like memory sharing 49 50options USERCONF # userconf(4) support 51#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 52options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 53 54# Alternate buffer queue strategies for better responsiveness under high 55# disk I/O load. 56#options BUFQ_READPRIO 57options BUFQ_PRIOCSCAN 58 59# Diagnostic/debugging support options 60#options DIAGNOSTIC # cheap kernel consistency checks 61options DEBUG # expensive debugging checks/support 62options PMAPDEBUG 63options DDB # in-kernel debugger 64#options DDB_HISTORY_SIZE=100 # Enable history editing in DDB 65#makeoptions DEBUG="-g" 66 67# Compatibility options 68include "conf/compat_netbsd50.config" 69#options COMPAT_LINUX # Linux binary compatibility 70#options COMPAT_OSSAUDIO # Linux binary compatibility 71 72# File systems 73file-system FFS # UFS 74file-system EXT2FS # second extended file system (linux) 75#file-system LFS # log-structured file system 76file-system MFS # memory file system 77file-system NFS # Network File System client 78#file-system NTFS # Windows/NT file system (experimental) 79file-system CD9660 # ISO 9660 + Rock Ridge file system 80file-system MSDOSFS # MS-DOS file system 81#file-system FDESC # /dev/fd 82file-system KERNFS # /kern 83file-system NULLFS # loopback file system 84#file-system OVERLAY # overlay file system 85file-system PROCFS # /proc 86#file-system UMAPFS # NULLFS + uid and gid remapping 87file-system UNION # union file system 88#file-system CODA # Coda File System; also needs vcoda (below) 89file-system PTYFS # /dev/pts/N support 90file-system TMPFS # Efficient memory file-system 91#file-system UDF # experimental - OSTA UDF CD/DVD file-system 92 93# File system options 94#options FFS_EI # FFS Endian Independent support 95#options FFS_NO_SNAPSHOT # No FFS snapshot support 96options QUOTA # legacy UFS quotas 97options QUOTA2 # new, in-filesystem UFS quotas 98options UFS_DIRHASH # UFS Large Directory Hashing 99options UFS_EXTATTR # Extended attribute support for UFS1 100options WAPBL # File system journaling support 101#options DISKLABEL_EI # disklabel Endian Independent support 102options NFSSERVER # Network File System server 103 104# Networking options 105#options GATEWAY # packet forwarding 106options INET # IP + ICMP + TCP + UDP 107options INET6 # IPv6 108#options IPSEC # IP security 109#options IPSEC_DEBUG # debug for IP security 110#options MROUTING # IP multicast routing 111#options PIM # Protocol Independent Multicast 112#options NETATALK # AppleTalk networking protocols 113options PPP_BSDCOMP # BSD-Compress compression support for PPP 114options PPP_DEFLATE # Deflate compression support for PPP 115options PPP_FILTER # Active filter support for PPP (requires bpf) 116#options TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG 117 118#options ALTQ # Manipulate network interfaces' output queues 119#options ALTQ_BLUE # Stochastic Fair Blue 120#options ALTQ_CBQ # Class-Based Queueing 121#options ALTQ_CDNR # Diffserv Traffic Conditioner 122#options ALTQ_FIFOQ # First-In First-Out Queue 123#options ALTQ_FLOWVALVE # RED/flow-valve (red-penalty-box) 124#options ALTQ_HFSC # Hierarchical Fair Service Curve 125#options ALTQ_LOCALQ # Local queueing discipline 126#options ALTQ_PRIQ # Priority Queueing 127#options ALTQ_RED # Random Early Detection 128#options ALTQ_RIO # RED with IN/OUT 129#options ALTQ_WFQ # Weighted Fair Queueing 130 131# These options enable verbose messages for several subsystems. 132# Warning, these may compile large string tables into the kernel!
