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 include "arch/cats/conf/std.cats" 22 23 options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25 # estimated number of users 26 27 maxusers 32 28 29 # Standard system options 30 31 options INSECURE # disable kernel securelevel 32 33 options RTC_OFFSET=0 # hardware clock is this many mins. west of GMT 34 options NTP # NTP phase/frequency locked loop 35 36 # experimental ELF support when used on a CATS board running ABLE 37 #options ABLEELF 38 #makeoptions ABLEELF="1" 39 40 # Enable experimental buffer queue strategy for better responsiveness under 41 # high disk I/O load.
