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 24 include "arch/sun2/conf/std.sun2" 25 26 #options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28 #ident "GENERIC-$Revision: 1.98 $" 29 30 makeoptions COPTS="-Os" # optimize for size 31 32 # Machines to be supported by this kernel 33 #options FPU_EMULATE 34 35 # Needs to be set per system. i.e change these as you see fit 36 maxusers 4 37 38 # Standard system options 39 options KTRACE # system call tracing 40 options SYSVMSG # System V message queues 41 options SYSVSEM # System V semaphores 42 options SYSVSHM # System V shared memory 43 #options INSECURE # disable kernel security level 44 #options USERCONF # userconf(4) support 45 #options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 46 #options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 47 48 # Enable experimental buffer queue strategy for better responsiveness under 49 # high disk I/O load.
