317 chomp ($variable{"PWD"} = `pwd`);
319 $config_help{"MACHINE"} = << "EOF"
320 The machine hostname that you will test.
321 For build only tests, it is still needed to differentiate log files.
324 $config_help{"SSH_USER"} = << "EOF"
325 The box is expected to have ssh on normal bootup, provide the user
326 (most likely root, since you need privileged operations)
329 $config_help{"BUILD_DIR"} = << "EOF"
330 The directory that contains the Linux source code (full path).
331 You can use \${PWD} that will be the path where ktest.pl is run, or use
332 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
335 $config_help{"OUTPUT_DIR"} = << "EOF"
336 The directory that the objects will be built (full path).
337 (can not be same as BUILD_DIR)
338 You can use \${PWD} that will be the path where ktest.pl is run, or use
339 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
342 $config_help{"BUILD_TARGET"} = << "EOF"
343 The location of the compiled file to copy to the target.
344 (relative to OUTPUT_DIR)
347 $config_help{"BUILD_OPTIONS"} = << "EOF"
348 Options to add to \"make\" when building.
352 $config_help{"TARGET_IMAGE"} = << "EOF"
353 The place to put your image on the test machine.
356 $config_help{"POWER_CYCLE"} = << "EOF"
357 A script or command to reboot the box.
359 Here is a digital loggers power switch example
360 POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
362 Here is an example to reboot a virtual box on the current host
363 with the name "Guest".
364 POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
367 $config_help{"CONSOLE"} = << "EOF"
368 The script or command that reads the console
370 If you use ttywatch server, something like the following would work.
371 CONSOLE = nc -d localhost 3001
373 For a virtual machine with guest name "Guest".
374 CONSOLE = virsh console Guest
377 $config_help{"LOCALVERSION"} = << "EOF"
378 Required version ending to differentiate the test
379 from other linux builds on the system.
382 $config_help{"REBOOT_TYPE"} = << "EOF"
383 Way to reboot the box to the test kernel.
384 Only valid options so far are "grub", "grub2", "syslinux", and "script".
386 If you specify grub, it will assume grub version 1
387 and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
388 and select that target to reboot to the kernel. If this is not
389 your setup, then specify "script" and have a command or script
390 specified in REBOOT_SCRIPT to boot to the target.
392 The entry in /boot/grub/menu.lst must be entered in manually.
393 The test will not modify that file.
395 If you specify grub2, then you also need to specify both \$GRUB_MENU
398 If you specify syslinux, then you may use SYSLINUX to define the syslinux
399 command (defaults to extlinux), and SYSLINUX_PATH to specify the path to
400 the syslinux install (defaults to /boot/extlinux). But you have to specify
401 SYSLINUX_LABEL to define the label to boot to for the test kernel.
404 $config_help{"GRUB_MENU"} = << "EOF"
405 The grub title name for the test kernel to boot
406 (Only mandatory if REBOOT_TYPE = grub or grub2)
408 Note, ktest.pl will not update the grub menu.lst, you need to
409 manually add an option for the test. ktest.pl will search
410 the grub menu.lst for this option to find what kernel to
413 For example, if in the /boot/grub/menu.lst the test kernel title has:
416 GRUB_MENU = Test Kernel
418 For grub2, a search of \$GRUB_FILE is performed for the lines
419 that begin with "menuentry". It will not detect submenus. The
420 menu must be a non-nested menu. Add the quotes used in the menu
421 to guarantee your selection, as the first menuentry with the content
422 of \$GRUB_MENU that is found will be used.
425 $config_help{"GRUB_FILE"} = << "EOF"
426 If grub2 is used, the full path for the grub.cfg file is placed
427 here. Use something like /boot/grub2/grub.cfg to search.
430 $config_help{"SYSLINUX_LABEL"} = << "EOF"
431 If syslinux is used, the label that boots the target kernel must
432 be specified with SYSLINUX_LABEL.
435 $config_help{"REBOOT_SCRIPT"} = << "EOF"
436 A script to reboot the target into the test kernel
437 (Only mandatory if REBOOT_TYPE = script)
