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/riscv/conf/std.riscv64" 22 23 options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25 #ident "GENERIC-$Revision: 1.4 $" 26 27 maxusers 64 # estimated number of users 28 29 # Standard system options 30 31 options NTP # NTP phase/frequency locked loop 32 33 options KTRACE # system call tracing via ktrace(1) 34 35 # Note: SysV IPC parameters could be changed dynamically, see sysctl(8). 36 options SYSVMSG # System V-like message queues 37 options SYSVSEM # System V-like semaphores 38 options SYSVSHM # System V-like memory sharing 39 40 options MODULAR # new style module(7) framework 41 options MODULAR_DEFAULT_AUTOLOAD 42 options USERCONF # userconf(4) support 43 #options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 44 options 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 49 options BUFQ_PRIOCSCAN 50 51 # Diagnostic/debugging support options 52 options 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" 62 makeoptions COPY_SYMTAB=1 63 options 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' 66 options 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 74 options COMPAT_70 # NetBSD 7.0 binary compatibility. 75 options COMPAT_43 # and 4.3BSD 76 77 options COMPAT_OSSAUDIO 78 options COMPAT_NETBSD32 79 #options COMPAT_LINUX 80 #options COMPAT_LINUX32 # req.
