1# $NetBSD: GENERIC,v 1.1 2007/12/17 19:09:02 garbled Exp $ 2# 3# GENERIC machine description file 4# 5# This machine description file is used to generate the default NetBSD 6# kernel. 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/rs6000/conf/std.rs6000" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#makeoptions COPTS="-O2 -mno-powerpc -mno-power" # wheeee 26 27#ident "GENERIC-$Revision: 1.1 $" 28 29maxusers 32 30 31# Platform support 32 33options PIC_IOCC 34 35# Standard system options 36 37options RTC_OFFSET=0 # hardware clock is this many mins. west of GMT 38options NTP # NTP phase/frequency locked loop 39 40options KTRACE # system call tracing via ktrace(1) 41options SYSTRACE # system call vetting via systrace(1) 42 43options SYSVMSG # System V-like message queues 44options SYSVSEM # System V-like semaphores 45#options SEMMNI=10 # number of semaphore identifiers 46#options SEMMNS=60 # number of semaphores in system 47#options SEMUME=10 # max number of undo entries per process 48#options SEMMNU=30 # number of undo structures in system 49options SYSVSHM # System V-like memory sharing 50#options SHMMAXPGS=1024 # 1024 pages is the default 51options P1003_1B_SEMAPHORE # p1003.1b semaphore support 52 53options LKM # loadable kernel modules 54 55options USERCONF # userconf(4) support 56#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 57options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 58 59# Enable experimental buffer queue strategy for better responsiveness under 60# high disk I/O load.
