390 $config_help{"MACHINE"} = << "EOF"
391 The machine hostname that you will test.
392 For build only tests, it is still needed to differentiate log files.
395 $config_help{"SSH_USER"} = << "EOF"
396 The box is expected to have ssh on normal bootup, provide the user
397 (most likely root, since you need privileged operations)
400 $config_help{"BUILD_DIR"} = << "EOF"
401 The directory that contains the Linux source code (full path).
402 You can use \${PWD} that will be the path where ktest.pl is run, or use
403 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
406 $config_help{"OUTPUT_DIR"} = << "EOF"
407 The directory that the objects will be built (full path).
408 (can not be same as BUILD_DIR)
409 You can use \${PWD} that will be the path where ktest.pl is run, or use
410 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
413 $config_help{"BUILD_TARGET"} = << "EOF"
414 The location of the compiled file to copy to the target.
415 (relative to OUTPUT_DIR)
418 $config_help{"BUILD_OPTIONS"} = << "EOF"
419 Options to add to \"make\" when building.
423 $config_help{"TARGET_IMAGE"} = << "EOF"
424 The place to put your image on the test machine.
427 $config_help{"POWER_CYCLE"} = << "EOF"
428 A script or command to reboot the box.
430 Here is a digital loggers power switch example
431 POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
433 Here is an example to reboot a virtual box on the current host
434 with the name "Guest".
435 POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
438 $config_help{"CONSOLE"} = << "EOF"
439 The script or command that reads the console
441 If you use ttywatch server, something like the following would work.
442 CONSOLE = nc -d localhost 3001
444 For a virtual machine with guest name "Guest".
445 CONSOLE = virsh console Guest
448 $config_help{"LOCALVERSION"} = << "EOF"
449 Required version ending to differentiate the test
450 from other linux builds on the system.
453 $config_help{"REBOOT_TYPE"} = << "EOF"
454 Way to reboot the box to the test kernel.
455 Only valid options so far are "grub", "grub2", "grub2bls", "syslinux", and "script".
457 If you specify grub, it will assume grub version 1
458 and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
459 and select that target to reboot to the kernel. If this is not
460 your setup, then specify "script" and have a command or script
461 specified in REBOOT_SCRIPT to boot to the target.
463 The entry in /boot/grub/menu.lst must be entered in manually.
464 The test will not modify that file.
466 If you specify grub2, then you also need to specify both \$GRUB_MENU
469 If you specify grub2bls, then you also need to specify \$GRUB_MENU.
471 If you specify syslinux, then you may use SYSLINUX to define the syslinux
472 command (defaults to extlinux), and SYSLINUX_PATH to specify the path to
473 the syslinux install (defaults to /boot/extlinux). But you have to specify
474 SYSLINUX_LABEL to define the label to boot to for the test kernel.
477 $config_help{"GRUB_MENU"} = << "EOF"
478 The grub title name for the test kernel to boot
479 (Only mandatory if REBOOT_TYPE = grub or grub2)
481 Note, ktest.pl will not update the grub menu.lst, you need to
482 manually add an option for the test. ktest.pl will search
483 the grub menu.lst for this option to find what kernel to
486 For example, if in the /boot/grub/menu.lst the test kernel title has:
489 GRUB_MENU = Test Kernel
491 For grub2, a search of \$GRUB_FILE is performed for the lines
492 that begin with "menuentry". It will not detect submenus. The
493 menu must be a non-nested menu. Add the quotes used in the menu
494 to guarantee your selection, as the first menuentry with the content
495 of \$GRUB_MENU that is found will be used.
497 For grub2bls, \$GRUB_MENU is searched on the result of \$GRUB_BLS_GET
498 command for the lines that begin with "title".
501 $config_help{"GRUB_FILE"} = << "EOF"
502 If grub2 is used, the full path for the grub.cfg file is placed
503 here. Use something like /boot/grub2/grub.cfg to search.
506 $config_help{"SYSLINUX_LABEL"} = << "EOF"
507 If syslinux is used, the label that boots the target kernel must
508 be specified with SYSLINUX_LABEL.
511 $config_help{"REBOOT_SCRIPT"} = << "EOF"
512 A script to reboot the target into the test kernel
513 (Only mandatory if REBOOT_TYPE = script)
