1# $NetBSD: GENERIC,v 1.28 2013/06/30 21:38:58 rmind 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: 1.28 $" 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) 41 42options SYSVMSG # System V-like message queues 43options SYSVSEM # System V-like semaphores 44#options SEMMNI=10 # number of semaphore identifiers 45#options SEMMNS=60 # number of semaphores in system 46#options SEMUME=10 # max number of undo entries per process 47#options SEMMNU=30 # number of undo structures in system 48options SYSVSHM # System V-like memory sharing 49 50options USERCONF # userconf(4) support 51#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 52options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 53 54# Enable experimental buffer queue strategy for better responsiveness under 55# high disk I/O load.
