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/dreamcast/conf/std.dreamcast" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25maxusers 16 # estimated number of users 26 27# Standard system options 28#options INSECURE # disable kernel security levels 29 30#options RTC_OFFSET=-540 31options HZ=100 # clock interrupt generates every 1/HZ sec 32options NTP # NTP phase/frequency locked loop 33 34options KTRACE # system call tracing via ktrace(1) 35options SYSTRACE # system call vetting via sistrace(1) 36 37options USERCONF # userconf(4) support 38#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 39options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 40 41options SYSVMSG # System V-like message queues 42options SYSVSEM # System V-like semaphores 43#options SEMMNI=10 # number of semaphore identifiers 44#options SEMMNS=60 # number of semaphores in system 45#options SEMUME=10 # max number of undo entries per process 46#options SEMMNU=30 # number of undo structures in system 47options SYSVSHM # System V-like memory sharing 48#options SHMMAXPGS=1024 # 1024 pages is the default 49options P1003_1B_SEMAPHORE # p1003.1b semaphore support 50 51# Diagnostic/debugging support options 52#options DIAGNOSTIC # cheap kernel consistency checks 53#options DEBUG # expensive debugging checks/support 54#options KMEMSTATS # kernel memory statistics (vmstat -m) 55options DDB # in-kernel debugger 56#options KGDB # remote debugger 57#options "KGDB_DEVNAME=\"scif\"",KGDB_DEVRATE=57600 58#makeoptions DEBUG="-g" # compile full symbol table 59options SYMTAB_SPACE=250000 60#options SYSCALL_DEBUG 61#options UVMHIST 62#options UVMHIST_PRINT 63 64# Compatibility options 65options COMPAT_16 # NetBSD 1.6, 66options COMPAT_20 # NetBSD 2.0, 67options COMPAT_30 # NetBSD 3.0 compatibility. 68options COMPAT_43 # and 4.3BSD 69#options TCP_COMPAT_42 # 4.2BSD TCP/IP bug compat.
