+# Config file for ktest.pl
+#
+# Place your customized version of this, in the working directory that
+# ktest.pl is run from. By default, ktest.pl will look for a file
+# called "ktest.conf", but you can name it anything you like and specify
+# the name of your config file as the first argument of 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. But all the sections must be either
+# DEFAULT or TEST_START, they can not be a mixture.
+#
+# TEST_START IF ${RUN_NET_TESTS}
+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
+#
+# ELSE IF ${RUN_DISK_TESTS}
+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-tests
+#
+# ELSE IF ${RUN_CPU_TESTS}
+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-cpu
+#
+# ELSE
+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
+#
+# The if statement may also have comparisons that will and for
+# == and !=, strings may be used for both sides.
+#
+# BOX_TYPE := x86_32
+#
+# DEFAULTS IF ${BOX_TYPE} == x86_32
+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-32
+# ELSE
+# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-64
+#
+# The DEFINED keyword can be used by the IF statements too.
+# It returns true if the given config variable or option has been defined
+# or false otherwise.
+#
+# 
+# DEFAULTS IF DEFINED USE_CC
+# CC := ${USE_CC}
+# ELSE
+# CC := gcc
+#
+#
+# As well as NOT DEFINED.
+#
+# DEFAULTS IF NOT DEFINED MAKE_CMD
+# MAKE_CMD := make ARCH=x86
+#
+#
+# And/or ops (&&,||) may also be used to make complex conditionals.
+#
+# TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf
+#
+# Notice the use of parentheses. Without any parentheses the above would be
+# processed the same as:
+#
+# TEST_START IF DEFINED ALL_TESTS || (${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
+
+# Signal to send to kill console.
+# ktest.pl will create a child process to monitor the console.
+# When the console is finished, ktest will kill the child process
+# with this signal.
+# (default INT)
+#CLOSE_CONSOLE_SIGNAL = HUP
+
+# Required version ending to differentiate the test
+# from other linux builds on the system.
+#LOCALVERSION = -test
+
+# For REBOOT_TYPE = grub2, you must specify where the grub.cfg
+# file is. This is the file that is searched to find the menu
+# option to boot to with GRUB_REBOOT
+#GRUB_FILE = /boot/grub2/grub.cfg
+
+# The tool for REBOOT_TYPE = grub2 to set the next reboot kernel
+# to boot into (one shot mode).
+# (default grub2_reboot)
+#GRUB_REBOOT = grub2_reboot
+
+# The grub title name for the test kernel to boot
+# (Only mandatory if REBOOT_TYPE = grub or grub2)
+#
+# 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
+#
+# For grub2, a search of top level "menuentry"s are done. No
+# submenu is searched. The menu is found by searching for the
+# contents of GRUB_MENU in the line that starts with "menuentry".
+# You may want to include the quotes around the option. For example:
+# for: menuentry 'Test Kernel'
+# do a: GRUB_MENU = 'Test Kernel'
+# For customizing, add your entry in /etc/grub.d/40_custom.
+#
+#GRUB_MENU = Test Kernel
+
+# For REBOOT_TYPE = syslinux, the name of the syslinux executable
+# (on the target) to use to set up the next reboot to boot the
+# test kernel.
+# (default extlinux)
+#SYSLINUX = syslinux
+
+# For REBOOT_TYPE = syslinux, the path that is passed to to the
+# syslinux command where syslinux is installed.
+# (default /boot/extlinux)
+#SYSLINUX_PATH = /boot/syslinux
+
+# For REBOOT_TYPE = syslinux, the syslinux label that references the
+# test kernel in the syslinux config file.
+# (default undefined)
+#SYSLINUX_LABEL = "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) ####
+
+# Email options for receiving notifications. Users must setup
+# the specified mailer prior to using this feature.
+#
+# (default undefined)
+#MAILTO =
+#
+# Supported mailers: sendmail, mail, mailx
+# (default sendmail)
+#MAILER = sendmail
+#
+# The executable to run
+# (default: for sendmail "/usr/sbin/sendmail", otherwise equals ${MAILER})
+#MAIL_EXEC = /usr/sbin/sendmail
+#
+# The command used to send mail, which uses the above options
+# can be modified. By default if the mailer is "sendmail" then
+#  MAIL_COMMAND = echo \'Subject: $SUBJECT\n\n$MESSAGE\' | $MAIL_PATH/$MAILER -t $MAILTO
+# For mail or mailx:
+#  MAIL_COMMAND = "$MAIL_PATH/$MAILER -s \'$SUBJECT\' $MAILTO <<< \'$MESSAGE\'
+# ktest.pl will do the substitution for MAIL_PATH, MAILER, MAILTO at the time
+#    it sends the mail if "$FOO" format is used. If "${FOO}" format is used,
+#    then the substitutions will occur at the time the config file is read.
+#    But note, MAIL_PATH and MAILER require being set by the config file if
+#     ${MAIL_PATH} or ${MAILER} are used, but not if $MAIL_PATH or $MAILER are.
+#MAIL_COMMAND = echo \'Subject: $SUBJECT\n\n$MESSAGE\' | $MAIL_PATH/$MAILER -t $MAILTO
+#
+# Errors are defined as those would terminate the script
+# (default 1)
+#EMAIL_ON_ERROR = 1
+# (default 1)
+#EMAIL_WHEN_FINISHED = 1
+# (default 0)
+#EMAIL_WHEN_STARTED = 1
+#
+# Users can cancel the test by Ctrl^C
+# (default 0)
+#EMAIL_WHEN_CANCELED = 1
+
+# 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

+# set, then the first test will take precedence.
+#
+# default (undefined)
+#PRE_KTEST = ${SSH} ~/set_up_test
+
+# If you want to execute some command after all the tests have
+# completed, you can set this option. Note, it can be set as a

+#POST_KTEST = ${SSH} ~/dismantle_test
+
+# The default test type (default test)
+# The test types may be:

+#   install - build and install, but do nothing else (does not reboot)
+#   boot    - build, install, 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

+#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 to do some special handling before installing
+# you can add a script with this option.
+# The environment variable KERNEL_VERSION will be set to the
+# kernel version that is used.
+#
+# default (undefined)
+#PRE_INSTALL = ssh user@target rm -rf '/lib/modules/*-test*'
+
+# 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
+
+# If for some reason you just want to boot the kernel and you do not
+# want the test to install anything new. For example, you may just want
+# to boot test the same kernel over and over and do not want to go through
+# the hassle of installing anything, you can set this option to 1
+# (default 0)
+#NO_INSTALL = 1
+
+# If there is a command that you want to run before the individual test

+#
+# One example may be if you must add a temporary patch to the build to

+#PRE_BUILD = cd ${BUILD_DIR} && patch -p1 < /tmp/temp.patch
+
+# To specify if the test should fail if the PRE_BUILD fails,

+
+# If there is a script that should run after the build is done

+
+# Way to reboot the box to the test kernel.
+# Only valid options so far are "grub", "grub2", "syslinux" 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.
+#
+# For REBOOT_TYPE = grub2, you must define both GRUB_MENU and
+# GRUB_FILE.
+#
+# For REBOOT_TYPE = syslinux, you must define SYSLINUX_LABEL, and
+# perhaps modify SYSLINUX (default extlinux) and SYSLINUX_PATH
+# (default /boot/extlinux)
+#
+# The entry in /boot/grub/menu.lst must be entered in manually.
+# The test will not modify that file.
+#REBOOT_TYPE = grub
+
+# If you are using a machine that doesn't boot with grub, and
+# perhaps gets its kernel from a remote server (tftp), then
+# you can use this option to update the target image with the
+# test image.
+#
+# You could also do the same with POST_INSTALL, but the difference
+# between that option and this option is that POST_INSTALL runs
+# after the install, where this one runs just before a reboot.
+# (default undefined)
+#SWITCH_TO_TEST = cp ${OUTPUT_DIR}/${BUILD_TARGET} ${TARGET_IMAGE}
+
+# If you are using a machine that doesn't boot with grub, and
+# perhaps gets its kernel from a remote server (tftp), then
+# you can use this option to update the target image with the
+# the known good image to reboot safely back into.
+#
+# This option holds a command that will execute before needing
+# to reboot to a good known image.
+# (default undefined)
+#SWITCH_TO_GOOD = ssh ${SSH_USER}/${MACHINE} cp good_image ${TARGET_IMAGE}
+
+# 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

+# (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.

+#
+# 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.
+#
+#
+# TEST_NAME = name
+#
+#  If you want the test to have a name that is displayed in
+#  the test result banner at the end of the test, then use this
+#  option. This is useful to search for the RESULT keyword and
+#  not have to translate a test number to a test in the config.
+#
+# 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_CHERRY if set to non zero, then git cherry will be
+#      performed against PATCHCHECK_START and PATCHCHECK_END. That is
+#
+#      git cherry ${PATCHCHECK_START} ${PATCHCHECK_END}
+#
+#      Then the changes found will be tested.
+#
+#      Note, PATCHCHECK_CHERRY requires PATCHCHECK_END to be defined.
+#      (default 0)
+#
+#  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, unless
+#     IGNORE_WARNINGS is set for the given commit's sha1
+#
+#   IGNORE_WARNINGS can be used to disable the failure of patchcheck
+#     on a particuler commit (SHA1). You can add more than one commit
+#     by adding a list of SHA1s that are space delimited.
+#
+#   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.
+#
+# BISECT_TRIES = 5 (optional, default 1)
+#
+#   For those cases that it takes several tries to hit a bug,
+#   the BISECT_TRIES is useful. It is the number of times the
+#   test is ran before it says the kernel is good. The first failure
+#   will stop trying and mark the current SHA1 as bad.
+#
+#   Note, as with all race bugs, there's no guarantee that if
+#   it succeeds, it is really a good bisect. But it helps in case
+#   the bug is some what reliable.
+#
+#   You can set BISECT_TRIES to zero, and all tests will be considered
+#   good, unless you also set BISECT_MANUAL.
+#
+# 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:
+#
+#   You can specify a good config with CONFIG_BISECT_GOOD, otherwise it
+#   will use the MIN_CONFIG, and if that's not specified, it will use
+#   the config that comes with "make defconfig".
+#
+#   It runs both the good and bad configs through a make oldconfig to
+#   make sure that they are set up for the kernel that is checked out.
+#
+#   It then reads the configs that are set, as well as the ones that are
+#   not set for both the good and bad configs, and then compares them.
+#   It will set half of the good configs within the bad config (note,
+#   "set" means to make the bad config match the good config, a config
+#   in the good config that is off, will be turned off in the bad
+#   config. That is considered a "set").
+#
+#   It tests this new config and if it works, it becomes the new good
+#   config, otherwise it becomes the new bad config. It continues this
+#   process until there's only one config left and it will report that
+#   config.
+#
+#   The "bad config" can also be a config that is needed to boot but was
+#   disabled because it depended on something that wasn't set.
+#
+#   During this process, it saves the current good and bad configs in
+#   ${TMP_DIR}/good_config and ${TMP_DIR}/bad_config respectively.
+#   If you stop the test, you can copy them to a new location to
+#   reuse them again.
+#
+#   Although the MIN_CONFIG may be the config it starts with, the
+#   MIN_CONFIG is ignored.
+#
+#  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, if MIN_CONFIG is not set
+#  It will build a config with "make defconfig"
+#
+# CONFIG_BISECT_CHECK (optional)
+#  Set this to 1 if you want to confirm that the config ktest
+#  generates (the bad config with the min config) is still bad.
+#  It may be that the min config fixes what broke the bad config
+#  and the test will not return a result.
+#  Set it to "good" to test only the good config and set it
+#  to "bad" to only test the bad config.
+#
+# CONFIG_BISECT_EXEC (optional)
+#  The config bisect is a separate program that comes with ktest.pl.
+#  By befault, it will look for:
+#    `pwd`/config-bisect.pl # the location ktest.pl was executed from.
+#  If it does not find it there, it will look for:
+#    `dirname <ktest.pl>`/config-bisect.pl # The directory that holds ktest.pl
+#  If it does not find it there, it will look for:
+#    ${BUILD_DIR}/tools/testing/ktest/config-bisect.pl
+#  Setting CONFIG_BISECT_EXEC will override where it looks.
+#
+# 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)
+#
+#  MIN_CONFIG_TYPE can be either 'boot' or 'test'. With 'boot' it will
+#   test if the created config can just boot the machine. If this is
+#   set to 'test', then the TEST option must be defined and the created
+#   config will not only boot the target, but also make sure that the
+#   config lets the test succeed. This is useful to make sure the final
+#   config that is generated allows network activity (ssh).
+#   (optional)
+#
+#  USE_OUTPUT_MIN_CONFIG set this to 1 if you do not want to be prompted
+#   about using the OUTPUT_MIN_CONFIG as the MIN_CONFIG as the starting
+#   point. Set it to 0 if you want to always just use the given MIN_CONFIG.
+#   If it is not defined, it will prompt you to pick which config
+#   to start with (MIN_CONFIG or OUTPUT_MIN_CONFIG).
+#
+# 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
+#  MIN_CONFIG_TYPE = test
+#  TEST = ssh ${USER}@${MACHINE} echo hi
+#
+#
+#
+#
+# For TEST_TYPE = make_warnings_file
+#
+# If you want the build to fail when a new warning is discovered
+# you set the WARNINGS_FILE to point to a file of known warnings.
+#
+# The test "make_warnings_file" will let you create a new warnings
+# file before you run other tests, like patchcheck.
+#
+# What this test does is to run just a build, you still need to
+# specify BUILD_TYPE to tell the test what type of config to use.
+# A BUILD_TYPE of nobuild will fail this test.
+#
+# The test will do the build and scan for all warnings. Any warning
+# it discovers will be saved in the WARNINGS_FILE (required) option.
+#
+# It is recommended (but not necessary) to make sure BUILD_NOCLEAN is
+# off, so that a full build is done (make mrproper is performed).
+# That way, all warnings will be captured.
+#
+# Example:
+#
+#  TEST_TYPE = make_warnings_file
+#  WARNINGS_FILE = ${OUTPUT_DIR}
+#  BUILD_TYPE = useconfig:oldconfig
+#  CHECKOUT = v3.8
+#  BUILD_NOCLEAN = 0
