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/next68k/conf/std.next68k" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.87 $" 26 27# Needs to be set per system. i.e change these as you see fit 28maxusers 16 29 30# Standard system options 31options KTRACE # system call tracing 32options SYSTRACE # system call vetting via systrace(1) 33options SYSVMSG # System V message queues 34options SYSVSEM # System V semaphores 35#options SEMMNI=10 # number of semaphore identifiers 36#options SEMMNS=60 # number of semaphores in system 37#options SEMUME=10 # max number of undo entries per process 38#options SEMMNU=30 # number of undo structures in system 39options SYSVSHM # System V shared memory 40options P1003_1B_SEMAPHORE # POSIX semaphore support 41#options SHMMAXPGS=1024 # 1024 pages is the default 42 43options LKM # loadable kernel modules 44options INSECURE # disable kernel security level 45options USERCONF # userconf(4) support 46#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 47options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 48 49# Enable experimental buffer queue strategy for better responsiveness under 50# high disk I/O load.
