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/dreamcast/conf/std.dreamcast" 22 23 options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25 maxusers 16 # estimated number of users 26 27 # Enable the hooks used for initializing the root memory-disk. 28 options MEMORY_DISK_HOOKS 29 options MEMORY_DISK_IS_ROOT # force root on memory disk 30 options MEMORY_DISK_SERVER=0 # no userspace memory disk support 31 options MEMORY_DISK_ROOT_SIZE=2880 # size of memory disk, in blocks 32 #options MEMORY_DISK_ROOT_SIZE=6000 33 34 # CPU support 35 options SH4 36 options SH7750 37 options PCLOCK=49900000 # 50MHz 38 #options PCLOCK=50000000 # 50MHz 39 options IOM_ROM_BEGIN=0x00000000 40 options IOM_ROM_SIZE=0x00100000 # 1MB 41 options IOM_RAM_BEGIN=0x8c000000 42 options IOM_RAM_SIZE=0x01000000 # 16MB 43 44 # Standard system options 45 #options UCONSOLE # users can use TIOCCONS (for xconsole) 46 #options INSECURE # disable kernel security levels 47 48 #options RTC_OFFSET=-540 49 options HZ=100 # clock interrupt generates every 1/HZ sec 50 #options NTP # NTP phase/frequency locked loop 51 52 #options KTRACE # system call tracing via ktrace(1) 53 54 #options USERCONF # userconf(4) support 55 #options PIPE_SOCKETPAIR # smaller, but slower pipe(2) 56 57 #options SYSVMSG # System V-like message queues 58 #options SYSVSEM # System V-like semaphores 59 #options SEMMNI=10 # number of semaphore identifiers 60 #options SEMMNS=60 # number of semaphores in system 61 #options SEMUME=10 # max number of undo entries per process 62 #options SEMMNU=30 # number of undo structures in system 63 #options SYSVSHM # System V-like memory sharing 64 #options SHMMAXPGS=1024 # 1024 pages is the default 65 66 # Diagnostic/debugging support options 67 #options DIAGNOSTIC # cheap kernel consistency checks 68 #options DEBUG # expensive debugging checks/support 69 #options DDB # in-kernel debugger 70 #options KGDB # remote debugger 71 #options "KGDB_DEVNAME=\"scif\"",KGDB_DEVRATE=57600 72 #makeoptions DEBUG="-g" # compile full symbol table 73 #options SYSCALL_DEBUG 74 #options UVMHIST 75 #options UVMHIST_PRINT 76 77 # Compatibility options 78 options COMPAT_43 # and 4.3BSD 79 80 # Executable format options 81 options EXEC_COFF # COFF executables 82 options EXEC_ELF32 # 32-bit ELF executables 83 84 # File systems 85 file-system FFS # UFS 86 file-system MFS # memory file system 87 file-system NFS # Network File System client 88 file-system PROCFS # /proc 89 file-system KERNFS # /kern 90 #file-system NULLFS # loopback file system 91 #file-system UMAPFS # NULLFS + uid and gid remapping 92 file-system CD9660 # CD-ROM file system 93 94 # File system options 95 #options QUOTA # UFS quotas 96 #options NFSSERVER # Network File System server 97 98 # Networking options 99 options INET # IP + ICMP + TCP + UDP 100 options NFS_BOOT_DHCP # Support DHCP NFS root 101 102 #options PCIVERBOSE # verbose PCI device autoconfig messages 103 #options PCI_CONFIG_DUMP # verbosely dump PCI config space 104 105 # Kernel root file system and dump configuration. 106 #config netbsd root on ? type nfs 107 #config netbsd root on wd0a type ffs 108 config netbsd root on ? type ? 109 110 111 # wscons options 112 options WSEMUL_VT100 # VT100 / VT220 emulation 113 options FONT_BOLD8x16 114 115 # 116 # Device configuration 117 # 118 119 mainbus0 at root 120 121 cpu* at mainbus? 122 shb* at mainbus? 123 124 # Serial Devices 125 #options SCIFCONSOLE 126 options SCIFCN_SPEED=57600 127 scif0 at shb? 128 129 pvr0 at shb? 130 wsdisplay* at pvr? console ? 131 132 maple0 at shb? 133 mkbd* at maple? port ? subunit ? 134 wskbd* at mkbd? console ? 135 136 gdrom0 at shb? 137 138 g2bus0 at shb? 139 gapspci* at g2bus? # GAPS PCI bridge 140 pci* at gapspci? 141 rtk* at pci? dev ? function ? # SEGA Broadband Adapter 142 ukphy* at mii? phy ? 143 144 #pseudo-device vnd 4 # disk-like interface to files 145 #pseudo-device bpfilter 8 # Berkeley packet filter 146 #pseudo-device bridge # simple inter-network bridging 147 #pseudo-device ipfilter # IP filter (firewall) and NAT 148 pseudo-device loop # network loopback 149 pseudo-device pty # pseudo-terminals 150 #pseudo-device ppp 2 # Point-to-Point Protocol 151 #pseudo-device pppoe # PPP over Ethernet (RFC 2516) 152 #pseudo-device tun 2 # network tunneling over tty 153 pseudo-device rnd # /dev/random and in-kernel generator 154 pseudo-device md 1 # memory disk device (ramdisk) 155
