306 $config_help{"MACHINE"} = << "EOF"
307 The machine hostname that you will test.
308 For build only tests, it is still needed to differentiate log files.
311 $config_help{"SSH_USER"} = << "EOF"
312 The box is expected to have ssh on normal bootup, provide the user
313 (most likely root, since you need privileged operations)
316 $config_help{"BUILD_DIR"} = << "EOF"
317 The directory that contains the Linux source code (full path).
318 You can use \${PWD} that will be the path where ktest.pl is run, or use
319 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
322 $config_help{"OUTPUT_DIR"} = << "EOF"
323 The directory that the objects will be built (full path).
324 (can not be same as BUILD_DIR)
325 You can use \${PWD} that will be the path where ktest.pl is run, or use
326 \${THIS_DIR} which is assigned \${PWD} but may be changed later.
329 $config_help{"BUILD_TARGET"} = << "EOF"
330 The location of the compiled file to copy to the target.
331 (relative to OUTPUT_DIR)
334 $config_help{"BUILD_OPTIONS"} = << "EOF"
335 Options to add to \"make\" when building.
339 $config_help{"TARGET_IMAGE"} = << "EOF"
340 The place to put your image on the test machine.
343 $config_help{"POWER_CYCLE"} = << "EOF"
344 A script or command to reboot the box.
346 Here is a digital loggers power switch example
347 POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
349 Here is an example to reboot a virtual box on the current host
350 with the name "Guest".
351 POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
354 $config_help{"CONSOLE"} = << "EOF"
355 The script or command that reads the console
357 If you use ttywatch server, something like the following would work.
358 CONSOLE = nc -d localhost 3001
360 For a virtual machine with guest name "Guest".
361 CONSOLE = virsh console Guest
364 $config_help{"LOCALVERSION"} = << "EOF"
365 Required version ending to differentiate the test
366 from other linux builds on the system.
369 $config_help{"REBOOT_TYPE"} = << "EOF"
370 Way to reboot the box to the test kernel.
371 Only valid options so far are "grub" and "script".
373 If you specify grub, it will assume grub version 1
374 and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
375 and select that target to reboot to the kernel. If this is not
376 your setup, then specify "script" and have a command or script
377 specified in REBOOT_SCRIPT to boot to the target.
379 The entry in /boot/grub/menu.lst must be entered in manually.
380 The test will not modify that file.
383 $config_help{"GRUB_MENU"} = << "EOF"
384 The grub title name for the test kernel to boot
385 (Only mandatory if REBOOT_TYPE = grub)
387 Note, ktest.pl will not update the grub menu.lst, you need to
388 manually add an option for the test. ktest.pl will search
389 the grub menu.lst for this option to find what kernel to
392 For example, if in the /boot/grub/menu.lst the test kernel title has:
395 GRUB_MENU = Test Kernel
398 $config_help{"REBOOT_SCRIPT"} = << "EOF"
399 A script to reboot the target into the test kernel
400 (Only mandatory if REBOOT_TYPE = script)
