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/riscv/conf/std.riscv64" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.10 $" 26 27maxusers 64 # estimated number of users 28 29# Standard system options 30 31options NTP # NTP phase/frequency locked loop 32 33options KTRACE # system call tracing via ktrace(1) 34 35# Note: SysV IPC parameters could be changed dynamically, see sysctl(8). 36options SYSVMSG # System V-like message queues 37options SYSVSEM # System V-like semaphores 38options SYSVSHM # System V-like memory sharing 39 40options MODULAR # new style module(7) framework 41options MODULAR_DEFAULT_AUTOLOAD 42options USERCONF # userconf(4) support 43#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 44options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 45 46# Alternate buffer queue strategies for better responsiveness under high 47# disk I/O load. 48#options BUFQ_READPRIO 49options BUFQ_PRIOCSCAN 50 51# Diagnostic/debugging support options 52options DIAGNOSTIC # inexpensive kernel consistency checks 53 # XXX to be commented out on release branch 54#options DEBUG # expensive debugging checks/support 55#options LOCKDEBUG # expensive locking checks/support 56 57# 58# Because gcc omits the frame pointer for any -O level, the line below 59# is needed to make backtraces in DDB work. 60# 61#makeoptions COPTS="-O2 -fno-omit-frame-pointer" 62makeoptions COPY_SYMTAB=1 63options DDB # in-kernel debugger 64#options DDB_COMMANDONENTER="bt" # execute command when ddb is entered 65#options DDB_ONPANIC=1 # see also sysctl(7): `ddb.onpanic' 66options DDB_HISTORY_SIZE=512 # enable history editing in DDB 67#options KGDB # remote debugger 68#options KGDB_DEVNAME="\"com\"",KGDB_DEVADDR=0x3f8,KGDB_DEVRATE=9600 69#options SYSCALL_STATS # per syscall counts 70#options SYSCALL_TIMES # per syscall times 71#options SYSCALL_TIMES_HASCOUNTER # use 'broken' rdtsc (soekris) 72 73# Compatibility options 74include "conf/compat_netbsd70.config" 75 76options COMPAT_OSSAUDIO 77#options COMPAT_NETBSD32 78#options EXEC_ELF32 79 80# Wedge support 81options DKWEDGE_AUTODISCOVER # Automatically add dk(4) instances 82options DKWEDGE_METHOD_GPT # Supports GPT partitions as wedges 83options DKWEDGE_METHOD_BSDLABEL # Support disklabel entries as wedges 84options DKWEDGE_METHOD_MBR # Support MBR partitions as wedges 85options DKWEDGE_METHOD_APPLE # Support Apple partitions as wedges 86#options DKWEDGE_METHOD_RDB # Support RDB partitions as wedges 87 88include "conf/filesystems.config" 89 90# File system options 91options QUOTA # legacy UFS quotas 92options QUOTA2 # new, in-filesystem UFS quotas 93#options DISKLABEL_EI # disklabel Endian Independent support 94options FFS_EI # FFS Endian Independent support 95options WAPBL # File system journaling support 96# Note that UFS_DIRHASH is suspected of causing kernel memory corruption. 97# It is not recommended for general use. 98#options UFS_DIRHASH # UFS Large Directory Hashing - Experimental 99options NFSSERVER # Network File System server 100#options EXT2FS_SYSTEM_FLAGS # makes ext2fs file flags (append and 101 # immutable) behave as system flags. 102#options FFS_NO_SNAPSHOT # No FFS snapshot support 103 104# Networking options 105#options GATEWAY # packet forwarding 106options INET # IP + ICMP + TCP + UDP 107options INET6 # IPV6 108options IPSEC # IP security 109#options IPSEC_DEBUG # debug for IP security 110#options MPLS # MultiProtocol Label Switching (needs mpls) 111#options MROUTING # IP multicast routing 112#options PIM # Protocol Independent Multicast 113#options NETATALK # AppleTalk networking protocols 114#options PPP_BSDCOMP # BSD-Compress compression support for PPP 115#options PPP_DEFLATE # Deflate compression support for PPP 116#options PPP_FILTER # Active filter support for PPP (requires bpf) 117#options TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG 118 119#options ALTQ # Manipulate network interfaces' output queues 120#options ALTQ_BLUE # Stochastic Fair Blue 121#options ALTQ_CBQ # Class-Based Queueing 122#options ALTQ_CDNR # Diffserv Traffic Conditioner 123#options ALTQ_FIFOQ # First-In First-Out Queue 124#options ALTQ_FLOWVALVE # RED/flow-valve (red-penalty-box) 125#options ALTQ_HFSC # Hierarchical Fair Service Curve 126#options ALTQ_LOCALQ # Local queueing discipline 127#options ALTQ_PRIQ # Priority Queueing 128#options ALTQ_RED # Random Early Detection 129#options ALTQ_RIO # RED with IN/OUT 130#options ALTQ_WFQ # Weighted Fair Queueing 131 132# These options enable verbose messages for several subsystems. 133# Warning, these may compile large string tables into the kernel! 134 135# Kernel root file system and dump configuration. 136config netbsd root on ?
