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/riscv/conf/std.riscv64" 22 23options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.2 $" 26 27maxusers 64 # estimated number of users 28 29# Standard system options 30 31options NTP # NTP phase/frequency locked loop 32 33options KTRACE # system call tracing via ktrace(1) 34 35# Note: SysV IPC parameters could be changed dynamically, see sysctl(8). 36options SYSVMSG # System V-like message queues 37options SYSVSEM # System V-like semaphores 38options SYSVSHM # System V-like memory sharing 39 40options MODULAR # new style module(7) framework 41options MODULAR_DEFAULT_AUTOLOAD 42options USERCONF # userconf(4) support 43#options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 44options SYSCTL_INCLUDE_DESCR # Include sysctl descriptions in kernel 45 46# Alternate buffer queue strategies for better responsiveness under high 47# disk I/O load. 48#options BUFQ_READPRIO 49options BUFQ_PRIOCSCAN 50 51# Diagnostic/debugging support options 52options DIAGNOSTIC # inexpensive kernel consistency checks 53 # XXX to be commented out on release branch 54#options DEBUG # expensive debugging checks/support 55#options LOCKDEBUG # expensive locking checks/support 56 57# 58# Because gcc omits the frame pointer for any -O level, the line below 59# is needed to make backtraces in DDB work. 60# 61#makeoptions COPTS="-O2 -fno-omit-frame-pointer" 62makeoptions COPY_SYMTAB=1 63options DDB # in-kernel debugger 64#options DDB_COMMANDONENTER="bt" # execute command when ddb is entered 65#options DDB_ONPANIC=1 # see also sysctl(7): `ddb.onpanic' 66options DDB_HISTORY_SIZE=512 # enable history editing in DDB 67#options KGDB # remote debugger 68#options KGDB_DEVNAME="\"com\"",KGDB_DEVADDR=0x3f8,KGDB_DEVRATE=9600 69#options SYSCALL_STATS # per syscall counts 70#options SYSCALL_TIMES # per syscall times 71#options SYSCALL_TIMES_HASCOUNTER # use 'broken' rdtsc (soekris) 72 73# Compatibility options 74options COMPAT_70 # NetBSD 7.0 binary compatibility. 75options COMPAT_43 # and 4.3BSD 76 77options COMPAT_OSSAUDIO 78options COMPAT_NETBSD32 79#options COMPAT_LINUX 80#options COMPAT_LINUX32 # req.
