1# 2# MINIMAL -- Mostly Minimal kernel configuration file for FreeBSD/amd64 3# 4# Many definitions of minimal are possible. The one this file follows is 5# GENERIC, minus all functionality that can be replaced by loading kernel 6# modules. 7# 8# Exceptions: 9# o While UFS is buildable as a module, the current module lacks 10# some features (ACL, GJOURNAL) that GENERIC includes. 11# o acpi as a module has been reported flakey and not well tested, so 12# is included in the kernel. 13# o random is included due to uncertaty... 14# o Many networking things are included 15# 16# For now, please run changes to these list past imp@freebsd.org 17# 18# For more information on this file, please read the config(5) manual page, 19# and/or the handbook section on Kernel Configuration Files: 20# 21# http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html 22# 23# The handbook is also available locally in /usr/share/doc/handbook 24# if you've installed the doc distribution, otherwise always see the 25# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the 26# latest information. 27# 28# An exhaustive list of options and more detailed explanations of the 29# device lines is also present in the ../../conf/NOTES and NOTES files. 30# If you are in doubt as to the purpose or necessity of a line, check first 31# in NOTES. 32# 33# $FreeBSD$ 34 35cpu HAMMER 36ident MINIMAL 37 38makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols 39makeoptions WITH_CTF=1 # Run ctfconvert(1) for DTrace support 40 41options SCHED_ULE # ULE scheduler 42options PREEMPTION # Enable kernel thread preemption 43options INET # InterNETworking 44options INET6 # IPv6 communications protocols 45options TCP_OFFLOAD # TCP offload 46options SCTP # Stream Control Transmission Protocol 47options FFS # Berkeley Fast Filesystem 48options SOFTUPDATES # Enable FFS soft updates support 49options UFS_ACL # Support for access control lists 50options UFS_DIRHASH # Improve performance on big directories 51options UFS_GJOURNAL # Enable gjournal-based UFS journaling 52options QUOTA # Enable disk quotas for UFS 53options MD_ROOT # MD is a potential root device 54options COMPAT_FREEBSD32 # Compatible with i386 binaries 55options COMPAT_FREEBSD4 # Compatible with FreeBSD4 56options COMPAT_FREEBSD5 # Compatible with FreeBSD5 57options COMPAT_FREEBSD6 # Compatible with FreeBSD6 58options COMPAT_FREEBSD7 # Compatible with FreeBSD7 59options COMPAT_FREEBSD9 # Compatible with FreeBSD9 60options COMPAT_FREEBSD10 # Compatible with FreeBSD10 61options COMPAT_FREEBSD11 # Compatible with FreeBSD11 62options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI 63options KTRACE # ktrace(1) support 64options STACK # stack(9) support 65options SYSVSHM # SYSV-style shared memory 66options SYSVMSG # SYSV-style message queues 67options SYSVSEM # SYSV-style semaphores 68options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions 69options PRINTF_BUFR_SIZE=128 # Prevent printf output being interspersed. 70options KBD_INSTALL_CDEV # install a CDEV entry in /dev 71options HWPMC_HOOKS # Necessary kernel hooks for hwpmc(4) 72options AUDIT # Security event auditing 73options CAPABILITY_MODE # Capsicum capability mode 74options CAPABILITIES # Capsicum capabilities 75options MAC # TrustedBSD MAC Framework 76options KDTRACE_FRAME # Ensure frames are compiled in 77options KDTRACE_HOOKS # Kernel DTrace hooks 78options DDB_CTF # Kernel ELF linker loads CTF data 79options INCLUDE_CONFIG_FILE # Include this file in kernel 80 81# Debugging support.
