1# 2# MINIMAL -- Mostly Minimal kernel configuration file for FreeBSD/i386 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 (non-loaded) random is included due to uncertainty... 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# https://docs.freebsd.org/en/books/handbook/kernelconfig/#kernelconfig-config 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 (https://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 I486_CPU 36cpu I586_CPU 37cpu I686_CPU 38ident MINIMAL 39 40makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols 41makeoptions WITH_CTF=1 # Run ctfconvert(1) for DTrace support 42 43options SCHED_ULE # ULE scheduler 44options PREEMPTION # Enable kernel thread preemption 45options INET # InterNETworking 46options INET6 # IPv6 communications protocols 47options TCP_OFFLOAD # TCP offload 48options SCTP_SUPPORT # Allow kldload of SCTP 49options FFS # Berkeley Fast Filesystem 50options SOFTUPDATES # Enable FFS soft updates support 51options UFS_ACL # Support for access control lists 52options UFS_DIRHASH # Improve performance on big directories 53options UFS_GJOURNAL # Enable gjournal-based UFS journaling 54options QUOTA # Enable disk quotas for UFS 55options MD_ROOT # MD is a potential root device 56options GEOM_LABEL # Provides labelization 57options COMPAT_FREEBSD4 # Compatible with FreeBSD4 58options COMPAT_FREEBSD5 # Compatible with FreeBSD5 59options COMPAT_FREEBSD6 # Compatible with FreeBSD6 60options COMPAT_FREEBSD7 # Compatible with FreeBSD7 61options COMPAT_FREEBSD9 # Compatible with FreeBSD9 62options COMPAT_FREEBSD10 # Compatible with FreeBSD10 63options COMPAT_FREEBSD11 # Compatible with FreeBSD11 64options COMPAT_FREEBSD12 # Compatible with FreeBSD12 65options COMPAT_FREEBSD13 # Compatible with FreeBSD13 66options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI 67options KTRACE # ktrace(1) support 68options STACK # stack(9) support 69options SYSVSHM # SYSV-style shared memory 70options SYSVMSG # SYSV-style message queues 71options SYSVSEM # SYSV-style semaphores 72options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions 73options PRINTF_BUFR_SIZE=128 # Prevent printf output being interspersed. 74options KBD_INSTALL_CDEV # install a CDEV entry in /dev 75options HWPMC_HOOKS # Necessary kernel hooks for hwpmc(4) 76options AUDIT # Security event auditing 77options CAPABILITY_MODE # Capsicum capability mode 78options CAPABILITIES # Capsicum capabilities 79options MAC # TrustedBSD MAC Framework 80options KDTRACE_FRAME # Ensure frames are compiled in 81options KDTRACE_HOOKS # Kernel DTrace hooks 82options DDB_CTF # Kernel ELF linker loads CTF data 83options INCLUDE_CONFIG_FILE # Include this file in kernel 84 85# Debugging support.
