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/macppc/conf/std.macppc" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.212 $" 26 27maxusers 32 28 29options ALTIVEC # Include AltiVec support 30 31# Standard system options 32options INSECURE # disable kernel security levels 33 34options RTC_OFFSET=0 # hardware clock is this many mins. west of GMT 35options NTP # NTP phase/frequency locked loop 36options KTRACE # system call tracing via ktrace(1) 37options SYSTRACE # system call vetting via systrace(1) 38 39options SYSVMSG # System V message queues 40options SYSVSEM # System V semaphores 41#options SEMMNI=10 # number of semaphore identifiers 42#options SEMMNS=60 # number of semaphores in system 43#options SEMUME=10 # max number of undo entries per process 44#options SEMMNU=30 # number of undo structures in system 45options SYSVSHM # System V shared memory 46#options SHMMAXPGS=1024 # 1024 pages is the default 47options P1003_1B_SEMAPHORE # p1003.1b semaphore support 48 49options LKM # loadable kernel modules 50 51options USERCONF # userconf(4) support 52#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 53options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 54 55# Enable experimental buffer queue strategy for better responsiveness under 56# high disk I/O load.
