371 # default variables that can be used
372 chomp ($variable{"PWD"} = `pwd`);
373 $pwd = $variable{"PWD"};
375 $config_help{"MACHINE"} = << "EOF"
376 The machine hostname that you will test.
377 For build only tests, it is still needed to differentiate log files.
380 $config_help{"SSH_USER"} = << "EOF"
381 The box is expected to have ssh on normal bootup, provide the user
382 (most likely root, since you need privileged operations)
385 $config_help{"BUILD_DIR"} = << "EOF"
386 The directory that contains the Linux source code (full path).
387 You can use \${PWD} that will be the path where ktest.pl is run, or use
388 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
391 $config_help{"OUTPUT_DIR"} = << "EOF"
392 The directory that the objects will be built (full path).
393 (can not be same as BUILD_DIR)
394 You can use \${PWD} that will be the path where ktest.pl is run, or use
395 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
398 $config_help{"BUILD_TARGET"} = << "EOF"
399 The location of the compiled file to copy to the target.
400 (relative to OUTPUT_DIR)
403 $config_help{"BUILD_OPTIONS"} = << "EOF"
404 Options to add to \"make\" when building.
408 $config_help{"TARGET_IMAGE"} = << "EOF"
409 The place to put your image on the test machine.
412 $config_help{"POWER_CYCLE"} = << "EOF"
413 A script or command to reboot the box.
415 Here is a digital loggers power switch example
416 POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
418 Here is an example to reboot a virtual box on the current host
419 with the name "Guest".
420 POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
423 $config_help{"CONSOLE"} = << "EOF"
424 The script or command that reads the console
426 If you use ttywatch server, something like the following would work.
427 CONSOLE = nc -d localhost 3001
429 For a virtual machine with guest name "Guest".
430 CONSOLE = virsh console Guest
433 $config_help{"LOCALVERSION"} = << "EOF"
434 Required version ending to differentiate the test
435 from other linux builds on the system.
438 $config_help{"REBOOT_TYPE"} = << "EOF"
439 Way to reboot the box to the test kernel.
440 Only valid options so far are "grub", "grub2", "syslinux", and "script".
442 If you specify grub, it will assume grub version 1
443 and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
444 and select that target to reboot to the kernel. If this is not
445 your setup, then specify "script" and have a command or script
446 specified in REBOOT_SCRIPT to boot to the target.
448 The entry in /boot/grub/menu.lst must be entered in manually.
449 The test will not modify that file.
451 If you specify grub2, then you also need to specify both \$GRUB_MENU
454 If you specify syslinux, then you may use SYSLINUX to define the syslinux
455 command (defaults to extlinux), and SYSLINUX_PATH to specify the path to
456 the syslinux install (defaults to /boot/extlinux). But you have to specify
457 SYSLINUX_LABEL to define the label to boot to for the test kernel.
460 $config_help{"GRUB_MENU"} = << "EOF"
461 The grub title name for the test kernel to boot
462 (Only mandatory if REBOOT_TYPE = grub or grub2)
464 Note, ktest.pl will not update the grub menu.lst, you need to
465 manually add an option for the test. ktest.pl will search
466 the grub menu.lst for this option to find what kernel to
469 For example, if in the /boot/grub/menu.lst the test kernel title has:
472 GRUB_MENU = Test Kernel
474 For grub2, a search of \$GRUB_FILE is performed for the lines
475 that begin with "menuentry". It will not detect submenus. The
476 menu must be a non-nested menu. Add the quotes used in the menu
477 to guarantee your selection, as the first menuentry with the content
478 of \$GRUB_MENU that is found will be used.
481 $config_help{"GRUB_FILE"} = << "EOF"
482 If grub2 is used, the full path for the grub.cfg file is placed
483 here. Use something like /boot/grub2/grub.cfg to search.
486 $config_help{"SYSLINUX_LABEL"} = << "EOF"
487 If syslinux is used, the label that boots the target kernel must
488 be specified with SYSLINUX_LABEL.
491 $config_help{"REBOOT_SCRIPT"} = << "EOF"
492 A script to reboot the target into the test kernel
493 (Only mandatory if REBOOT_TYPE = script)
