| # |
| # 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. |
| # |
| # (default undefined) |
| #ADD_CONFIG = /home/test/config-broken |
| |
| # 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) |
| # Note, this is a DEFAULT section only option. |
| # (default undefined) |
| #LOG_FILE = /home/test/logfiles/target.log |
| |
| # Remove old logfile if it exists before starting all tests. |
| # Note, this is a DEFAULT section only option. |
| # (default 0) |
| #CLEAR_LOG = 0 |
| |
| # Line to define a successful boot up in console output. |
| # This is what the line contains, not the entire line. If you need |
| # the entire line to match, then use regural expression syntax like: |
| # (do not add any quotes around it) |
| # |
| # SUCCESS_LINE = ^MyBox Login:$ |
| # |
| # (default "login:") |
| #SUCCESS_LINE = login: |

| |
| # In case the console constantly fills the screen, having |
| # a specified time to stop the test after failure is recommended. |
| # (in seconds) |
| # (default 60) |
| #STOP_AFTER_FAILURE = 60 |
| |
| # In case the console constantly fills the screen, having |
| # a specified time to stop the test if it never succeeds nor fails |
| # is recommended. |
| # Note: this is ignored if a success or failure is detected. |
| # (in seconds) |
| # (default 600, -1 is to never stop) |
| #STOP_TEST_AFTER = 600 |
| |
| # Stop testing if a build fails. If set, the script will end if |
| # a failure is detected, otherwise it will save off the .config, |
| # dmesg and bootlog in a directory called |
| # MACHINE-TEST_TYPE_BUILD_TYPE-fail-yyyymmddhhmmss |
| # if the STORE_FAILURES directory is set. |
| # (default 1) |
| # Note, even if this is set to zero, there are some errors that still |
| # stop the tests. |
| #DIE_ON_FAILURE = 1 |
| |
| # Directory to store failure directories on failure. If this is not |

| # (in seconds) (default 1) |
| #BOOTED_TIMEOUT = 1 |
| |
| # The timeout in seconds when we consider the box hung after |
| # the console stop producing output. Be sure to leave enough |
| # time here to get pass a reboot. Some machines may not produce |
| # any console output for a long time during a reboot. You do |
| # not want the test to fail just because the system was in |
| # the process of rebooting to the test kernel. |
| # (default 120) |
| #TIMEOUT = 120 |
| |
| # In between tests, a reboot of the box may occur, and this |
| # is the time to wait for the console after it stops producing |
| # output. Some machines may not produce a large lag on reboot |
| # so this should accommodate it. |
| # The difference between this and TIMEOUT, is that TIMEOUT happens |
| # when rebooting to the test kernel. This sleep time happens |
| # after a test has completed and we are about to start running |
| # another test. If a reboot to the reliable kernel happens, |
| # we wait SLEEP_TIME for the console to stop producing output |
| # before starting the next test. |

| #### Per test run options #### |
| # The following options are only allowed in TEST_START sections. |
| # They are ignored in the DEFAULTS sections. |
| # |
| # All of these are optional and undefined by default, although |
| # some of these options are required for TEST_TYPE of patchcheck |
| # and bisect. |
| # |
| # |
| # CHECKOUT = branch |
| # |
| # If the BUILD_DIR is a git repository, then you can set this option |
| # to checkout the given branch before running the TEST. If you |
| # specify this for the first run, that branch will be used for |
| # all preceding tests until a new CHECKOUT is set. |
| # |
| # |
| # |
| # 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/Ā¢onfig-bad |
| # MIN_CONFIG = /home/test/config-min |
| # BISECT_MANUAL = 1 |
