# # Config file for ktest.pl # # Note, all paths must be absolute # # Options set in the beginning of the file are considered to be # default options. These options can be overriden by test specific # options, with the following exceptions: # # LOG_FILE # CLEAR_LOG # POWEROFF_ON_SUCCESS # REBOOT_ON_SUCCESS # # Test specific options are set after the label: # # TEST_START # # The options after a TEST_START label are specific to that test. # Each TEST_START label will set up a new test. If you want to # perform a test more than once, you can add the ITERATE label # to it followed by the number of times you want that test # to iterate. If the ITERATE is left off, the test will only # be performed once. # # TEST_START ITERATE 10 # # You can skip a test by adding SKIP (before or after the ITERATE # and number) # # TEST_START SKIP # # TEST_START SKIP ITERATE 10 # # TEST_START ITERATE 10 SKIP # # The SKIP label causes the options and the test itself to be ignored. # This is useful to set up several different tests in one config file, and # only enabling the ones you want to use for a current test run. # # You can add default options anywhere in the file as well # with the DEFAULTS tag. This allows you to have default options # after the test options to keep the test options at the top # of the file. You can even place the DEFAULTS tag between # test cases (but not in the middle of a single test case) # # TEST_START # MIN_CONFIG = /home/test/config-test1 # # DEFAULTS # MIN_CONFIG = /home/test/config-default # # TEST_START ITERATE 10 # # The above will run the first test with MIN_CONFIG set to # /home/test/config-test-1. Then 10 tests will be executed # with MIN_CONFIG with /home/test/config-default. # # You can also disable defaults with the SKIP option # # DEFAULTS SKIP # MIN_CONFIG = /home/test/config-use-sometimes # # DEFAULTS # MIN_CONFIG = /home/test/config-most-times # # The above will ignore the first MIN_CONFIG. If you want to # use the first MIN_CONFIG, remove the SKIP from the first # DEFAULTS tag and add it to the second. Be careful, options # may only be declared once per test or default. If you have # the same option name under the same test or as default # ktest will fail to execute, and no tests will run. # # DEFAULTS OVERRIDE # # Options defined in the DEFAULTS section can not be duplicated # even if they are defined in two different DEFAULT sections. # This is done to catch mistakes where an option is added but # the previous option was forgotten about and not commented. # # The OVERRIDE keyword can be added to a section to allow this # section to override other DEFAULT sections values that have # been defined previously. It will only override options that # have been defined before its use. Options defined later # in a non override section will still error. The same option # can not be defined in the same section even if that section # is marked OVERRIDE. # # # # Both TEST_START and DEFAULTS sections can also have the IF keyword # The value after the IF must evaluate into a 0 or non 0 positive # integer, and can use the config variables (explained below). # # DEFAULTS IF ${IS_X86_32} # # The above will process the DEFAULTS section if the config # variable IS_X86_32 evaluates to a non zero positive integer # otherwise if it evaluates to zero, it will act the same # as if the SKIP keyword was used. # # The ELSE keyword can be used directly after a section with # a IF statement. # # TEST_START IF ${RUN_NET_TESTS} # BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network # # ELSE # # BUILD_TYPE = useconfig:${CONFIG_DIR}/config-normal # # # The ELSE keyword can also contain an IF statement to allow multiple # if then else sections.

Without any paranthesis the above would be # processed the same as: # # TEST_START IF DEFINED ALL_TESTS || (${MYTEST} == boottest && ${MACHINE} == gandalf) # # # # INCLUDE file # # The INCLUDE keyword may be used in DEFAULT sections. This will # read another config file and process that file as well. The included # file can include other files, add new test cases or default # statements. Config variables will be passed to these files and changes # to config variables will be seen by top level config files. Including # a file is processed just like the contents of the file was cut and pasted # into the top level file, except, that include files that end with # TEST_START sections will have that section ended at the end of # the include file. That is, an included file is included followed # by another DEFAULT keyword. # # Unlike other files referenced in this config, the file path does not need # to be absolute. If the file does not start with '/', then the directory # that the current config file was located in is used. If no config by the # given name is found there, then the current directory is searched. # # INCLUDE myfile # DEFAULT # # is the same as: # # INCLUDE myfile # # Note, if the include file does not contain a full path, the file is # searched first by the location of the original include file, and then # by the location that ktest.pl was executed in. # #### Config variables #### # # This config file can also contain "config variables". # These are assigned with ":=" instead of the ktest option # assigment "=". # # The difference between ktest options and config variables # is that config variables can be used multiple times, # where each instance will override the previous instance. # And that they only live at time of processing this config. # # The advantage to config variables are that they can be used # by any option or any other config variables to define thing # that you may use over and over again in the options. # # For example: # # USER := root # TARGET := mybox # TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test # # TEST_START # MIN_CONFIG = config1 # TEST = ${TEST_CASE} # # TEST_START # MIN_CONFIG = config2 # TEST = ${TEST_CASE} # # TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test2 # # TEST_START # MIN_CONFIG = config1 # TEST = ${TEST_CASE} # # TEST_START # MIN_CONFIG = config2 # TEST = ${TEST_CASE} # # TEST_DIR := /home/me/test # # BUILD_DIR = ${TEST_DIR}/linux.git # OUTPUT_DIR = ${TEST_DIR}/test # # Note, the config variables are evaluated immediately, thus # updating TARGET after TEST_CASE has been assigned does nothing # to TEST_CASE. # # As shown in the example, to evaluate a config variable, you # use the ${X} convention. Simple $X will not work. # # If the config variable does not exist, the ${X} will not # be evaluated. Thus: # # MAKE_CMD = PATH=/mypath:${PATH} make # # If PATH is not a config variable, then the ${PATH} in # the MAKE_CMD option will be evaluated by the shell when # the MAKE_CMD option is passed into shell processing. #### Using options in other options #### # # Options that are defined in the config file may also be used # by other options. All options are evaulated at time of # use (except that config variables are evaluated at config # processing time). # # If an ktest option is used within another option, instead of # typing it again in that option you can simply use the option # just like you can config variables. # # MACHINE = mybox # # TEST = ssh root@${MACHINE} /path/to/test # # The option will be used per test case. Thus: # # TEST_TYPE = test # TEST = ssh root@{MACHINE} # # TEST_START # MACHINE = box1 # # TEST_START # MACHINE = box2 # # For both test cases, MACHINE will be evaluated at the time # of the test case. The first test will run ssh root@box1 # and the second will run ssh root@box2. #### Mandatory Default Options #### # These options must be in the default section, although most # may be overridden by test options. # The machine hostname that you will test #MACHINE = target # The box is expected to have ssh on normal bootup, provide the user # (most likely root, since you need privileged operations) #SSH_USER = root # The directory that contains the Linux source code #BUILD_DIR = /home/test/linux.git # The directory that the objects will be built # (can not be same as BUILD_DIR) #OUTPUT_DIR = /home/test/build/target # The location of the compiled file to copy to the target # (relative to OUTPUT_DIR) #BUILD_TARGET = arch/x86/boot/bzImage # The place to put your image on the test machine #TARGET_IMAGE = /boot/vmlinuz-test # A script or command to reboot the box # # Here is a digital loggers power switch example #POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin@power/outlet?5=CCL' # # Here is an example to reboot a virtual box on the current host # with the name "Guest". #POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest # The script or command that reads the console # # If you use ttywatch server, something like the following would work. #CONSOLE = nc -d localhost 3001 # # For a virtual machine with guest name "Guest". #CONSOLE = virsh console Guest # Required version ending to differentiate the test # from other linux builds on the system. #LOCALVERSION = -test # The grub title name for the test kernel to boot # (Only mandatory if REBOOT_TYPE = grub) # # Note, ktest.pl will not update the grub menu.lst, you need to # manually add an option for the test. ktest.pl will search # the grub menu.lst for this option to find what kernel to # reboot into. # # For example, if in the /boot/grub/menu.lst the test kernel title has: # title Test Kernel # kernel vmlinuz-test #GRUB_MENU = Test Kernel # A script to reboot the target into the test kernel # This and SWITCH_TO_TEST are about the same, except # SWITCH_TO_TEST is run even for REBOOT_TYPE = grub. # This may be left undefined. # (default undefined) #REBOOT_SCRIPT = #### Optional Config Options (all have defaults) #### # Start a test setup.

(Can't reboot, want to inspect each iteration) # Doing a BISECT_MANUAL will have the test wait for you to # tell it if the test passed or failed after each iteration. # This is basicall the same as running git bisect yourself # but ktest will rebuild and install the kernel for you. # # BISECT_CHECK = 1 (optional, default 0) # # Just to be sure the good is good and bad is bad, setting # BISECT_CHECK to 1 will start the bisect by first checking # out BISECT_BAD and makes sure it fails, then it will check # out BISECT_GOOD and makes sure it succeeds before starting # the bisect (it works for BISECT_REVERSE too). # # You can limit the test to just check BISECT_GOOD or # BISECT_BAD with BISECT_CHECK = good or # BISECT_CHECK = bad, respectively. # # BISECT_RET_GOOD = 0 (optional, default undefined) # # In case the specificed test returns something other than just # 0 for good, and non-zero for bad, you can override 0 being # good by defining BISECT_RET_GOOD. # # BISECT_RET_BAD = 1 (optional, default undefined) # # In case the specificed test returns something other than just # 0 for good, and non-zero for bad, you can override non-zero being # bad by defining BISECT_RET_BAD. # # BISECT_RET_ABORT = 255 (optional, default undefined) # # If you need to abort the bisect if the test discovers something # that was wrong, you can define BISECT_RET_ABORT to be the error # code returned by the test in order to abort the bisect. # # BISECT_RET_SKIP = 2 (optional, default undefined) # # If the test detects that the current commit is neither good # nor bad, but something else happened (another bug detected) # you can specify BISECT_RET_SKIP to an error code that the # test returns when it should skip the current commit. # # BISECT_RET_DEFAULT = good (optional, default undefined) # # You can override the default of what to do when the above # options are not hit. This may be one of, "good", "bad", # "abort" or "skip" (without the quotes). # # Note, if you do not define any of the previous BISECT_RET_* # and define BISECT_RET_DEFAULT, all bisects results will do # what the BISECT_RET_DEFAULT has. # # # Example: # TEST_START # TEST_TYPE = bisect # BISECT_GOOD = v2.6.36 # BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e # BISECT_TYPE = build # MIN_CONFIG = /home/test/config-bisect # # # # For TEST_TYPE = config_bisect # # In those cases that you have two different configs. One of them # work, the other does not, and you do not know what config causes # the problem. # The TEST_TYPE config_bisect will bisect the bad config looking for # what config causes the failure. # # The way it works is this: # # First it finds a config to work with. Since a different version, or # MIN_CONFIG may cause different dependecies, it must run through this # preparation. # # Overwrites any config set in the bad config with a config set in # either the MIN_CONFIG or ADD_CONFIG. Thus, make sure these configs # are minimal and do not disable configs you want to test: # (ie. # CONFIG_FOO is not set). # # An oldconfig is run on the bad config and any new config that # appears will be added to the configs to test. # # Finally, it generates a config with the above result and runs it # again through make oldconfig to produce a config that should be # satisfied by kconfig. # # Then it starts the bisect. # # The configs to test are cut in half. If all the configs in this # half depend on a config in the other half, then the other half # is tested instead. If no configs are enabled by either half, then # this means a circular dependency exists and the test fails. # # A config is created with the test half, and the bisect test is run. # # If the bisect succeeds, then all configs in the generated config # are removed from the configs to test and added to the configs that # will be enabled for all builds (they will be enabled, but not be part # of the configs to examine). # # If the bisect fails, then all test configs that were not enabled by # the config file are removed from the test. These configs will not # be enabled in future tests. Since current config failed, we consider # this to be a subset of the config that we started with. # # When we are down to one config, it is considered the bad config. # # Note, the config chosen may not be the true bad config. Due to # dependencies and selections of the kbuild system, mulitple # configs may be needed to cause a failure. If you disable the # config that was found and restart the test, if the test fails # again, it is recommended to rerun the config_bisect with a new # bad config without the found config enabled. # # The option BUILD_TYPE will be ignored. # # CONFIG_BISECT_TYPE is the type of test to perform: # build - bad fails to build # boot - bad builds but fails to boot # test - bad boots but fails a test # # CONFIG_BISECT is the config that failed to boot # # If BISECT_MANUAL is set, it will pause between iterations. # This is useful to use just ktest.pl just for the config bisect. # If you set it to build, it will run the bisect and you can # control what happens in between iterations. It will ask you if # the test succeeded or not and continue the config bisect. # # CONFIG_BISECT_GOOD (optional) # If you have a good config to start with, then you # can specify it with CONFIG_BISECT_GOOD. Otherwise # the MIN_CONFIG is the base. # # Example: # TEST_START # TEST_TYPE = config_bisect # CONFIG_BISECT_TYPE = build # CONFIG_BISECT = /home/test/config-bad # MIN_CONFIG = /home/test/config-min # BISECT_MANUAL = 1 # # # # For TEST_TYPE = make_min_config # # After doing a make localyesconfig, your kernel configuration may # not be the most useful minimum configuration. Having a true minimum # config that you can use against other configs is very useful if # someone else has a config that breaks on your code. By only forcing # those configurations that are truly required to boot your machine # will give you less of a chance that one of your set configurations # will make the bug go away. This will give you a better chance to # be able to reproduce the reported bug matching the broken config. # # Note, this does take some time, and may require you to run the # test over night, or perhaps over the weekend. But it also allows # you to interrupt it, and gives you the current minimum config # that was found till that time. # # Note, this test automatically assumes a BUILD_TYPE of oldconfig # and its test type acts like boot. # TODO: add a test version that makes the config do more than just # boot, like having network access. # # To save time, the test does not just grab any option and test # it. The Kconfig files are examined to determine the dependencies # of the configs. If a config is chosen that depends on another # config, that config will be checked first. By checking the # parents first, we can eliminate whole groups of configs that # may have been enabled. # # For example, if a USB device config is chosen and depends on CONFIG_USB, # the CONFIG_USB will be tested before the device. If CONFIG_USB is # found not to be needed, it, as well as all configs that depend on # it, will be disabled and removed from the current min_config. # # OUTPUT_MIN_CONFIG is the path and filename of the file that will # be created from the MIN_CONFIG. If you interrupt the test, set # this file as your new min config, and use it to continue the test. # This file does not need to exist on start of test. # This file is not created until a config is found that can be removed. # If this file exists, you will be prompted if you want to use it # as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG # is not defined. # (required field) # # START_MIN_CONFIG is the config to use to start the test with. # you can set this as the same OUTPUT_MIN_CONFIG, but if you do # the OUTPUT_MIN_CONFIG file must exist. # (default MIN_CONFIG) # # IGNORE_CONFIG is used to specify a config file that has configs that # you already know must be set. Configs are written here that have # been tested and proved to be required. It is best to define this # file if you intend on interrupting the test and running it where # it left off. New configs that it finds will be written to this file # and will not be tested again in later runs. # (optional) # # Example: # # TEST_TYPE = make_min_config # OUTPUT_MIN_CONFIG = /path/to/config-new-min # START_MIN_CONFIG = /path/to/config-min # IGNORE_CONFIG = /path/to/config-tested #
