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 21# Supports Sun2 (2/120, 2/170, 2/50, ...) 22# Supports root on: ie0, sd*, ... 23 24include "arch/sun2/conf/std.sun2" 25 26options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28#ident "GENERIC-$Revision: 1.31 $" 29 30# Machines to be supported by this kernel 31#options FPU_EMULATE 32 33# Needs to be set per system. i.e change these as you see fit 34maxusers 8 35 36# Standard system options 37options KTRACE # system call tracing 38options SYSTRACE # system call vetting via systrace(1) 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 48options LKM # loadable kernel modules 49#options INSECURE # disable kernel security level 50options USERCONF # userconf(4) support 51#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 52 53# Enable experimental buffer queue strategy for better responsiveness under 54# high disk I/O load.
