+# 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.

+#### 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_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_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
+#
+# Example:
+#   TEST_START
+#   TEST_TYPE = config_bisect
+#   CONFIG_BISECT_TYPE = build
+#   CONFIG_BISECT = /home/test/˘onfig-bad
+#   MIN_CONFIG = /home/test/config-min
