943 novaboot - A tool for booting various operating systems on various hardware or in qemu
949 B<novaboot> [option]... [--] script...
951 B<./script> [option]...
955 This program makes booting of an operating system (e.g. NOVA or Linux)
956 as simple as running a local program. It facilitates booting on local
957 or remote hosts or in emulators such as qemu. Novaboot operation is
958 controlled by command line options and by a so called novaboot script,
959 which can be thought as a generalization of bootloader configuration
960 files (see L</"NOVABOOT SCRIPT SYNTAX">). Based on this input,
961 novaboot setups everything for the target host to boot the desired
962 configuration, i.e. it generates the bootloader configuration file in
963 the proper format, deploy the binaries and other needed files to
964 required locations, perhaps on a remote boot server and reset the
965 target host. Finally, target host's serial output is redirected to
966 standard output if that is possible.
968 Typical way of using novaboot is to make the novaboot script
969 executable and set its first line to I<#!/usr/bin/env novaboot>. Then,
970 booting a particular OS configuration becomes the same as executing a
971 local program - the novaboot script.
973 For example, with C<novaboot> you can:
979 Run an OS in Qemu. This is the default action when no other action is
980 specified by command line switches. Thus running C<novaboot ./script>
981 (or C<./script> as described above) will run Qemu and make it boot the
982 configuration specified in the F<script>.
986 Create a bootloader configuration file (currently supported
987 bootloaders are GRUB, GRUB2, Pulsar and U-Boot) and copy it with all
988 other files needed for booting to a remote boot server.
990 ./script --server=192.168.1.1:/tftp --iprelay=192.168.1.2
992 This command copies files to the TFTP server and uses
993 TCP/IP-controlled relay to reset the target host and receive its
998 Run DHCP and TFTP server on developer's machine to PXE-boot the target
1001 ./script --dhcp-tftp
1003 When a PXE-bootable machine is connected via Ethernet to developer's
1004 machine, it will boot the configuration described in I<script>.
1008 Create bootable ISO images. E.g.
1010 novaboot --iso -- script1 script2
1012 The created ISO image will have GRUB bootloader installed on it and
1013 the boot menu will allow selecting between I<script1> and I<script2>
1018 Note that the options needed for a specific target can be stored in a
1019 L</"CONFIGURATION FILE">. Then it is sufficient to use only the B<-t>
1020 option to specify the name of the target.
1022 =head1 PHASES AND OPTIONS
1024 Novaboot performs its work in several phases. Each phase can be
1025 influenced by several options, certain phases can be skipped. The list
1026 of phases (in the execution order) and the corresponding options
1029 =head2 Configuration reading phase
1031 After starting, novaboot reads configuration files. By default, it
1032 searches for files named F<.novaboot> starting from the directory of
1033 the novaboot script (or working directory, see bellow) and continuing
1034 upwards up to the root directory. The configuration files are read in
1035 order from the root directory downwards with latter files overriding
1036 settings from the former ones.
1038 In certain cases, the location of the novaboot script cannot be
1039 determined in this early phase. This happens either when the script is
1040 read from the standard input or when novaboot is invoked explicitly
1041 and options precede the script name, as in the example L</"4."> above.
1042 In this case the current working directory is used as a starting point
1043 for configuration file search.
1047 =item -c, --config=I<filename>
1049 Use the specified configuration file instead of the default one(s).
1053 =head2 Command line processing phase
1059 Dump the current configuration to stdout end exits. Useful as an
1060 initial template for a configuration file.
1064 Print short (B<-h>) or long (B<--help>) help.
1066 =item -t, --target=I<target>
1068 This option serves as a user configurable shortcut for other novaboot
1069 options. The effect of this option is the same as the options stored
1070 in the C<%targets> configuration variable under key I<target>. See
1071 also L</"CONFIGURATION FILE">.
1075 =head2 Script preprocessing phase
1077 This phases allows to modify the parsed novaboot script before it is
1078 used in the later phases.
1082 =item -a, --append=I<parameters>
1084 Append a string to the first C<load> line in the novaboot script. This
1085 can be used to append parameters to the kernel's or root task's
1086 command line. Can appear multiple times.
1090 Use F<bender> chainloader. Bender scans the PCI bus for PCI serial
1091 ports and stores the information about them in the BIOS data area for
1094 =item --chainloader=I<chainloader>
1096 Chainloader that is loaded before the kernel and other files specified
1097 in the novaboot script. E.g. 'bin/boot/bender promisc'.
1101 Print the modules to boot and their parameters after this phase
1102 finishes. Then exit. This is useful for seeing the effect of other
1103 options in this section.
1105 =item -k, --kernel=F<file>
1107 Replace the first word on the first C<load> line in the novaboot
1108 script with F<file>.
1110 =item --scriptmod=I<perl expression>
1112 When novaboot script is read, I<perl expression> is executed for every
1113 line (in $_ variable). For example, C<novaboot
1114 --scriptmod=s/sigma0/omega6/g> replaces every occurrence of I<sigma0>
1115 in the script with I<omega6>.
1117 When this option is present, it overrides I<$script_modifier> variable
1118 from the configuration file, which has the same effect. If this option
1119 is given multiple times all expressions are evaluated in the command
1124 =head2 File generation phase
1126 In this phase, files needed for booting are generated in a so called
1127 I<build directory> (see L</--build-dir>). In most cases configuration
1128 for a bootloader is generated automatically by novaboot. It is also
1129 possible to generate other files using I<heredoc> or I<"<"> syntax in
1130 novaboot scripts. Finally, binaries can be generated in this phases by
1131 running C<scons> or C<make>.
1135 =item --build-dir=I<directory>
1137 Overrides the default build directory location.
1139 The default build directory location is determined as follows: If the
1140 configuration file defines the C<$builddir> variable, its value is
1141 used. Otherwise, it is the directory that contains the first processed
1144 See also L</BUILDDIR> variable.
1146 =item -g, --grub[=I<filename>]
1148 Generates grub bootloader menu file. If the I<filename> is not
1149 specified, F<menu.lst> is used. The I<filename> is relative to the
1150 build directory (see B<--build-dir>).
1152 =item --grub-preamble=I<prefix>
1154 Specifies the I<preable> that is at the beginning of the generated
1155 GRUB or GRUB2 config files. This is useful for specifying GRUB's
1158 =item --grub-prefix=I<prefix>
1160 Specifies I<prefix> that is put in front of every file name in GRUB's
1161 F<menu.lst>. The default value is the absolute path to the build directory.
1163 If the I<prefix> contains string $NAME, it will be replaced with the
1164 name of the novaboot script (see also B<--name>).
1166 =item --grub2[=I<filename>]
1168 Generate GRUB2 menuentry in I<filename>. If I<filename> is not
1169 specified F<grub.cfg> is used. The content of the menuentry can be
1170 customized with B<--grub-preable>, B<--grub2-prolog> or
1171 B<--grub_prefix> options.
1173 In order to use the the generated menuentry on your development
1174 machine that uses GRUB2, append the following snippet to
1175 F</etc/grub.d/40_custom> file and regenerate your grub configuration,
1176 i.e. run update-grub on Debian/Ubuntu.
1178 if [ -f /path/to/nul/build/grub.cfg ]; then
1179 source /path/to/nul/build/grub.cfg
1182 =item --grub2-prolog=I<prolog>
1184 Specifies text I<preable> that is put at the beginning of the entry
1187 =item -m, --make[=make command]
1189 Runs C<make> to build files that are not generated by novaboot itself.
1191 =item --name=I<string>
1193 Use the name I<string> instead of the name of the novaboot script.
1194 This name is used for things like a title of grub menu or for the
1195 server directory where the boot files are copied to.
1199 Do not generate files on the fly (i.e. "<" syntax) except for the
1200 files generated via "<<WORD" syntax.
1202 =item -p, --pulsar[=mac]
1204 Generates pulsar bootloader configuration file named F<config-I<mac>>
1205 The I<mac> string is typically a MAC address and defaults to
1208 =item --scons[=scons command]
1210 Runs C<scons> to build files that are not generated by novaboot
1215 Strip I<rom://> prefix from command lines and generated config files.
1216 The I<rom://> prefix is used by NUL. For NRE, it has to be stripped.
1220 Exit novaboot after file generation phase.
1224 =head2 Target connection check
1226 If supported by the target, the connection to it is made and it is
1227 checked whether the target is not occupied by another novaboot
1232 =item --amt=I<"[user[:password]@]host[:port]>
1234 Use Intel AMT to connect to target. Using SOL redirection and WS management
1235 to powercycle it. The IP address or FQDN of the PC is given by I<host>
1236 parameter. If I<password> is not specified, environment variable
1237 AMT_PASSWORD is used. I<port> is defining port number for SOL,
1238 if not specified, default is 16992. Default I<user> is admin.
1240 =item --iprelay=I<addr[:port]>
1242 Use TCP/IP relay and serial port to access the target's serial port
1243 and powercycle it. The IP address of the relay is given by I<addr>
1244 parameter. If I<port> is not specified, it default to 23.
1246 Note: This option is supposed to work with HWG-ER02a IP relays.
1248 =item -s, --serial[=device]
1250 Target's serial line is connected to host's serial line (device). The
1251 default value for device is F</dev/ttyUSB0>.
1253 The value of this option is exported in NB_NOVABOOT environment
1254 variable to all subprocesses run by C<novaboot>.
1256 =item --stty=I<settings>
1258 Specifies settings passed to C<stty> invoked on the serial line
1259 specified with B<--serial> option. If this option is not given,
1260 C<stty> is called with C<raw -crtscts -onlcr 115200> settings.
1262 =item --remote-cmd=I<cmd>
1264 Command that mediates connection to the target's serial line. For
1265 example C<ssh server 'cu -l /dev/ttyS0'>.
1267 =item --remote-expect=I<string>
1269 Wait for reception of I<string> after establishing the the remote
1270 connection before continuing.
1275 =head2 File deployment phase
1277 In some setups, it is necessary to copy the files needed for booting
1278 to a particular location, e.g. to a TFTP boot server or to the
1283 =item -d, --dhcp-tftp
1285 Turns your workstation into a DHCP and TFTP server so that the OS can
1286 be booted via PXE BIOS (or similar mechanism) on the test machine
1287 directly connected by a plain Ethernet cable to your workstation.
1289 The DHCP and TFTP servers require root privileges and C<novaboot>
1290 uses C<sudo> command to obtain those. You can put the following to

1295 your_login ALL=NOPASSWD: NOVABOOT
1297 =item --iso[=filename]
1299 Generates the ISO image that boots NOVA system via GRUB. If no filename
1300 is given, the image is stored under I<NAME>.iso, where I<NAME> is the name
1301 of the novaboot script (see also B<--name>).
1303 =item --server[=[[user@]server:]path]
1305 Copy all files needed for booting to another location (implies B<-g>
1306 unless B<--grub2> is given). The files will be copied (by B<rsync>
1307 tool) to the directory I<path>. If the I<path> contains string $NAME,
1308 it will be replaced with the name of the novaboot script (see also
1313 If B<--server> is used and its value ends with $NAME, then after
1314 copying the files, a new bootloader configuration file (e.g. menu.lst)
1315 is created at I<path-wo-name>, i.e. the path specified by B<--server>
1316 with $NAME part removed. The content of the file is created by
1317 concatenating all files of the same name from all subdirectories of
1318 I<path-wo-name> found on the "server".
1320 =item --rsync-flags=I<flags>
1322 Specifies which I<flags> are appended to F<rsync> command line when
1323 copying files as a result of I<--server> option.
1327 =head2 Target power-on and reset phase
1333 Switch on/off the target machine. Currently works only with
1336 =item -Q, --qemu[=I<qemu-binary>]
1338 Boot the configuration in qemu. Optionally, the name of qemu binary
1339 can be specified as a parameter.
1341 =item --qemu-append=I<flags>
1343 Append I<flags> to the default qemu flags (QEMU_FLAGS variable or
1344 C<-cpu coreduo -smp 2>).
1346 =item -q, --qemu-flags=I<flags>
1348 Replace the default qemu flags (QEMU_FLAGS variable or C<-cpu coreduo
1349 -smp 2>) with I<flags> specified here.
1351 =item --reset-cmd=I<cmd>
1353 Command that resets the target.
1357 =head2 Interaction with the bootloader on the target
1363 Interact with uBoot bootloader to boot the thing described in the
1364 novaboot script. Implementation of this option is currently tied to a
1365 particular board that we use. It may be subject to changes in the
1370 Command(s) to send the U-Boot bootloader before loading the images and
1375 =head2 Target interaction phase
1377 In this phase, target's serial output is redirected to stdout and if
1378 stdin is a TTY, it is redirected to the target's serial input allowing
1379 interactive work with the target.
1383 =item --exiton=I<string>
1385 When I<string> is sent by the target, novaboot exits. This option can
1386 be specified multiple times.
1388 If I<string> is C<-re>, then the next B<--exiton>'s I<string> is
1389 treated as regular expression. For example:
1391 --exiton -re --exiton 'error:.*failed'
1393 =item -i, --interactive
1395 Setup things for interactive use of target. Your terminal will be
1396 switched to raw mode. In raw mode, your system does not process input
1397 in any way (no echoing of entered characters, no interpretation
1398 special characters). This, among others, means that Ctrl-C is passed
1399 to the target and does no longer interrupt novaboot. Use "~~."
1400 sequence to exit novaboot.
1402 =item --expect=I<string>
1404 When I<string> is received from the target, send the string specified
1405 with the subsequent B<--send*> option to the target.
1407 =item --expect-re=I<regex>
1409 When target's output matches regular expression I<regex>, send the
1410 string specified with the subsequent B<--send*> option to the target.
1412 =item --expect-raw=I<perl-code>
1414 Provides direct control over Perl's Expect module.
1416 =item --send=I<string>
1418 Send I<string> to the target after the previously specified
1419 B<--expect*> was matched in the target's output. The I<string> may
1420 contain escape sequences such as "\n".
1422 Note that I<string> is actually interpreted by Perl, so it can contain
1423 much more that escape sequences. This behavior may change in the
1426 Example: C<--expect='login: ' --send='root\n'>
1428 =item --sendcont=I<string>
1430 Similar to B<--send> but continue expecting more input.
1432 Example: C<--expect='Continue?' --sendcont='yes\n'>
1436 =head1 NOVABOOT SCRIPT SYNTAX
1438 The syntax tries to mimic POSIX shell syntax. The syntax is defined
1439 with the following rules.
1441 Lines starting with "#" and empty lines are ignored.
1443 Lines that end with "\" are concatenated with the following line after
1444 removal of the final "\" and leading whitespace of the following line.
1446 Lines of the form I<VARIABLE=...> (i.e. matching '^[A-Z_]+=' regular
1447 expression) assign values to internal variables. See L</VARIABLES>
1450 Lines starting with C<load> keyword represent modules to boot. The
1451 word after C<load> is a file name (relative to the build directory
1452 (see B<--build-dir>) of the module to load and the remaining words are
1453 passed to it as the command line parameters.
1455 When the C<load> line ends with "<<WORD" then the subsequent lines
1456 until the line containing solely WORD are copied literally to the file
1457 named on that line. This is similar to shell's heredoc feature.
1459 When the C<load> line ends with "< CMD" then command CMD is executed
1460 with F</bin/sh> and its standard output is stored in the file named on
1461 that line. The SRCDIR variable in CMD's environment is set to the
1462 absolute path of the directory containing the interpreted novaboot
1467 #!/usr/bin/env novaboot
1468 load bzImage console=ttyS0,115200
1469 load rootfs.cpio < gen_cpio buildroot/images/rootfs.cpio "myapp->/etc/init.d/S99myapp"
1471 Example (NOVA User Land - NUL):
1473 #!/usr/bin/env novaboot
1474 WVDESC=Example program
1475 load bin/apps/sigma0.nul S0_DEFAULT script_start:1,1 \
1476 verbose hostkeyb:0,0x60,1,12,2
1477 load bin/apps/hello.nul
1478 load hello.nulconfig <<EOF
1479 sigma0::mem:16 name::/s0/log name::/s0/timer name::/s0/fs/rom ||
1480 rom://bin/apps/hello.nul
1483 This example will load three modules: F<sigma0.nul>, F<hello.nul> and
1484 F<hello.nulconfig>. sigma0 receives some command line parameters and
1485 F<hello.nulconfig> file is generated on the fly from the lines between
1486 C<<<EOF> and C<EOF>.
1490 The following variables are interpreted in the novaboot script:
1496 Novaboot chdir()s to this directory before file generation phase. The
1497 directory name specified here is relative to the build directory
1498 specified by other means (see L</--build-dir>).
1502 Assigning this variable has the same effect as specifying L</--exiton>
1505 =item HYPERVISOR_PARAMS
1507 Parameters passed to hypervisor. The default value is "serial", unless
1508 overridden in configuration file.
1512 The kernel to use instead of the hypervisor specified in the
1513 configuration file with the C<$hypervisor> variable. The value should
1514 contain the name of the kernel image as well as its command line
1515 parameters. If this variable is defined and non-empty, the variable
1516 HYPERVISOR_PARAMS is not used.
1520 Use a specific qemu binary (can be overridden with B<-Q>) and flags
1521 when booting this script under qemu. If QEMU_FLAGS variable is also
1522 specified flags specified in QEMU variable are replaced by those in
1527 Use specific qemu flags (can be overridden with B<-q>).
1531 Description of the wvtest-compliant program.
1533 =item WVTEST_TIMEOUT
1535 The timeout in seconds for WvTest harness. If no complete line appears
1536 in the test output within the time specified here, the test fails. It
1537 is necessary to specify this for long running tests that produce no
1538 intermediate output.
1542 =head1 CONFIGURATION FILE
1544 Novaboot can read its configuration from one or more files. By
1545 default, novaboot looks for files named F<.novaboot> as described in
1546 L</Configuration reading phase>. Alternatively, its location can be
1547 specified with the B<-c> switch or with the NOVABOOT_CONFIG
1548 environment variable. The configuration file has perl syntax and
1549 should set values of certain Perl variables. The current configuration
1550 can be dumped with the B<--dump-config> switch. Some configuration
1551 variables can be overridden by environment variables (see below) or by
1552 command line switches.
1554 Supported configuration variables include:
1560 Build directory location relative to the location of the configuration
1563 =item $default_target
1565 Default target (see below) to use when no target is explicitly
1566 specified on command line with the B<--target> option.
1570 Hash of shortcuts to be used with the B<--target> option. If the hash
1571 contains, for instance, the following pair of values
1573 'mybox' => '--server=boot:/tftproot --serial=/dev/ttyUSB0 --grub',
1575 then the following two commands are equivalent:
1577 ./script --server=boot:/tftproot --serial=/dev/ttyUSB0 --grub
1582 =head1 ENVIRONMENT VARIABLES
1584 Some options can be specified not only via config file or command line
1585 but also through environment variables. Environment variables override
1586 the values from configuration file and command line parameters
1587 override the environment variables.
1591 =item NOVABOOT_CONFIG
1593 Name of the novaboot configuration file to use instead of the default
1596 =item NOVABOOT_BENDER
1598 Defining this variable has the same meaning as B<--bender> option.
