- #
- # 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.
- #
- #### 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
- # (Only mandatory if REBOOT_TYPE = script)
- #REBOOT_SCRIPT =
- #### Optional Config Options (all have defaults) ####
- # Start a test setup. If you leave this off, all options
- # will be default and the test will run once.
- # This is a label and not really an option (it takes no value).
- # You can append ITERATE and a number after it to iterate the
- # test a number of times, or SKIP to ignore this test.
- #
- #TEST_START
- #TEST_START ITERATE 5
- #TEST_START SKIP
- # Have the following options as default again. Used after tests
- # have already been defined by TEST_START. Optionally, you can
- # just define all default options before the first TEST_START
- # and you do not need this option.
- #
- # This is a label and not really an option (it takes no value).
- # You can append SKIP to this label and the options within this
- # section will be ignored.
- #
- # DEFAULTS
- # DEFAULTS SKIP
- # The default test type (default test)
- # The test types may be:
- # build - only build the kernel, do nothing else
- # boot - build and boot the kernel
- # test - build, boot and if TEST is set, run the test script
- # (If TEST is not set, it defaults back to boot)
- # bisect - Perform a bisect on the kernel (see BISECT_TYPE below)
- # patchcheck - Do a test on a series of commits in git (see PATCHCHECK below)
- #TEST_TYPE = test
- # Test to run if there is a successful boot and TEST_TYPE is test.
- # Must exit with 0 on success and non zero on error
- # default (undefined)
- #TEST = ssh user@machine /root/run_test
- # The build type is any make config type or special command
- # (default randconfig)
- # nobuild - skip the clean and build step
- # useconfig:/path/to/config - use the given config and run
- # oldconfig on it.
- # This option is ignored if TEST_TYPE is patchcheck or bisect
- #BUILD_TYPE = randconfig
- # The make command (default make)
- # If you are building a 32bit x86 on a 64 bit host
- #MAKE_CMD = CC=i386-gcc AS=i386-as make ARCH=i386
- # Any build options for the make of the kernel (not for other makes, like configs)
- # (default "")
- #BUILD_OPTIONS = -j20
- # If you need an initrd, you can add a script or code here to install
- # it. The environment variable KERNEL_VERSION will be set to the
- # kernel version that is used. Remember to add the initrd line
- # to your grub menu.lst file.
- #
- # Here's a couple of examples to use:
- #POST_INSTALL = ssh user@target /sbin/mkinitrd --allow-missing -f /boot/initramfs-test.img $KERNEL_VERSION
- #
- # or on some systems:
- #POST_INSTALL = ssh user@target /sbin/dracut -f /boot/initramfs-test.img $KERNEL_VERSION
- # Way to reboot the box to the test kernel.
- # Only valid options so far are "grub" and "script"
- # (default grub)
- # If you specify grub, it will assume grub version 1
- # and will search in /boot/grub/menu.lst for the title $GRUB_MENU
- # and select that target to reboot to the kernel. If this is not
- # your setup, then specify "script" and have a command or script
- # specified in REBOOT_SCRIPT to boot to the target.
- #
- # The entry in /boot/grub/menu.lst must be entered in manually.
- # The test will not modify that file.
- #REBOOT_TYPE = grub
- # The min config that is needed to build for the machine
- # A nice way to create this is with the following:
- #
- # $ ssh target
- # $ lsmod > mymods
- # $ scp mymods host:/tmp
- # $ exit
- # $ cd linux.git
- # $ rm .config
- # $ make LSMOD=mymods localyesconfig
- # $ grep '^CONFIG' .config > /home/test/config-min
- #
- # If you want even less configs:
- #
- # log in directly to target (do not ssh)
- #
- # $ su
- # # lsmod | cut -d' ' -f1 | xargs rmmod
- #
- # repeat the above several times
- #
- # # lsmod > mymods
- # # reboot
- #
- # May need to reboot to get your network back to copy the mymods
- # to the host, and then remove the previous .config and run the
- # localyesconfig again. The CONFIG_MIN generated like this will
- # not guarantee network activity to the box so the TEST_TYPE of
- # test may fail.
- #
- # You might also want to set:
- # CONFIG_CMDLINE="<your options here>"
- # randconfig may set the above and override your real command
- # line options.
- # (default undefined)
- #MIN_CONFIG = /home/test/config-min
- # Sometimes there's options that just break the boot and
- # you do not care about. Here are a few:
- # # CONFIG_STAGING is not set
- # Staging drivers are horrible, and can break the build.
- # # CONFIG_SCSI_DEBUG is not set
- # SCSI_DEBUG may change your root partition
- # # CONFIG_KGDB_SERIAL_CONSOLE is not set
- # KGDB may cause oops waiting for a connection that's not there.
- # This option points to the file containing config options that will be prepended
- # to the MIN_CONFIG (or be the MIN_CONFIG if it is not set)
- #
- # Note, config options in MIN_CONFIG will override these options.

- # The location on the host where to write temp files
- # (default /tmp/ktest)
- #TMP_DIR = /tmp/ktest
- # Optional log file to write the status (recommended)

- # For TEST_TYPE = patchcheck
- #
- # This expects the BUILD_DIR to be a git repository, and
- # will checkout the PATCHCHECK_START commit.
- #
- # The option BUILD_TYPE will be ignored.
- #
- # The MIN_CONFIG will be used for all builds of the patchcheck. The build type
- # used for patchcheck is oldconfig.
- #
- # PATCHCHECK_START is required and is the first patch to
- # test (the SHA1 of the commit). You may also specify anything
- # that git checkout allows (branch name, tage, HEAD~3).
- #
- # PATCHCHECK_END is the last patch to check (default HEAD)
- #
- # PATCHCHECK_TYPE is required and is the type of test to run:
- # build, boot, test.
- #
- # Note, the build test will look for warnings, if a warning occurred
- # in a file that a commit touches, the build will fail.
- #
- # If BUILD_NOCLEAN is set, then make mrproper will not be run on
- # any of the builds, just like all other TEST_TYPE tests. But
- # what makes patchcheck different from the other tests, is if
- # BUILD_NOCLEAN is not set, only the first and last patch run
- # make mrproper. This helps speed up the test.
- #
- # Example:
- # TEST_START
- # TEST_TYPE = patchcheck
- # CHECKOUT = mybranch
- # PATCHCHECK_TYPE = boot
- # PATCHCHECK_START = 747e94ae3d1b4c9bf5380e569f614eb9040b79e7
- # PATCHCHECK_END = HEAD~2

- #
- # For TEST_TYPE = bisect
- #
- # You can specify a git bisect if the BUILD_DIR is a git repository.
- # The MIN_CONFIG will be used for all builds of the bisect. The build type
- # used for bisecting is oldconfig.
- #
- # The option BUILD_TYPE will be ignored.
- #
- # 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
- #
- # BISECT_GOOD is the commit (SHA1) to label as good (accepts all git good commit types)
- # BISECT_BAD is the commit to label as bad (accepts all git bad commit types)
- #
- # The above three options are required for a bisect operation.
- #
- # BISECT_REPLAY = /path/to/replay/file (optional, default undefined)
- #
- # If an operation failed in the bisect that was not expected to
- # fail. Then the test ends. The state of the BUILD_DIR will be
- # left off at where the failure occurred. You can examine the
- # reason for the failure, and perhaps even find a git commit
- # that would work to continue with. You can run:
- #
- # git bisect log > /path/to/replay/file
- #
- # The adding:
- #
- # BISECT_REPLAY= /path/to/replay/file
- #
- # And running the test again. The test will perform the initial
- # git bisect start, git bisect good, and git bisect bad, and
- # then it will run git bisect replay on this file, before
- # continuing with the bisect.
- #
- # BISECT_START = commit (optional, default undefined)
- #
- # As with BISECT_REPLAY, if the test failed on a commit that
- # just happen to have a bad commit in the middle of the bisect,
- # and you need to skip it. If BISECT_START is defined, it
- # will checkout that commit after doing the initial git bisect start,
- # git bisect good, git bisect bad, and running the git bisect replay
- # if the BISECT_REPLAY is set.
- #
- # BISECT_SKIP = 1 (optional, default 0)
- #
- # If BISECT_TYPE is set to test but the build fails, ktest will
- # simply fail the test and end their. You could use BISECT_REPLAY
- # and BISECT_START to resume after you found a new starting point,
- # or you could set BISECT_SKIP to 1. If BISECT_SKIP is set to 1,
- # when something other than the BISECT_TYPE fails, ktest.pl will
- # run "git bisect skip" and try again.
- #
- # BISECT_FILES = <path> (optional, default undefined)
- #
- # To just run the git bisect on a specific path, set BISECT_FILES.
- # For example:
- #
- # BISECT_FILES = arch/x86 kernel/time
- #
- # Will run the bisect with "git bisect start -- arch/x86 kernel/time"
- #
- # BISECT_REVERSE = 1 (optional, default 0)
- #
- # In those strange instances where it was broken forever
- # and you are trying to find where it started to work!
- # Set BISECT_GOOD to the commit that was last known to fail
- # Set BISECT_BAD to the commit that is known to start working.
- # With BISECT_REVERSE = 1, The test will consider failures as
- # good, and success as bad.
- #
- # BISECT_MANUAL = 1 (optional, default 0)
- #
- # In case there's a problem with automating the bisect for
- # whatever reason. (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.
- #
- # 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.
- #
- # Example:
- # TEST_START
- # TEST_TYPE = config_bisect
- # CONFIG_BISECT_TYPE = build
- # CONFIG_BISECT = /home/test/¢onfig-bad
- # MIN_CONFIG = /home/test/config-min
- # BISECT_MANUAL = 1
