   2# Config file for ktest.pl
   3#
 
 
 
 
 
   4# Note, all paths must be absolute
   5#
   6
   7# Options set in the beginning of the file are considered to be
   8# default options. These options can be overriden by test specific
   9# options, with the following exceptions:
  10#
  11#  LOG_FILE
  12#  CLEAR_LOG
  13#  POWEROFF_ON_SUCCESS
  14#  REBOOT_ON_SUCCESS
  15#
  16# Test specific options are set after the label:
  17#
  18# TEST_START
  19#
  20# The options after a TEST_START label are specific to that test.
  21# Each TEST_START label will set up a new test. If you want to
  22# perform a test more than once, you can add the ITERATE label
  23# to it followed by the number of times you want that test
  24# to iterate. If the ITERATE is left off, the test will only
  25# be performed once.
  26#
  27# TEST_START ITERATE 10
  28#
  29# You can skip a test by adding SKIP (before or after the ITERATE
  30# and number)
  31#
  32# TEST_START SKIP
  33#
  34# TEST_START SKIP ITERATE 10
  35#
  36# TEST_START ITERATE 10 SKIP
  37#
  38# The SKIP label causes the options and the test itself to be ignored.
  39# This is useful to set up several different tests in one config file, and
  40# only enabling the ones you want to use for a current test run.
  41#
  42# You can add default options anywhere in the file as well
  43# with the DEFAULTS tag. This allows you to have default options
  44# after the test options to keep the test options at the top
  45# of the file. You can even place the DEFAULTS tag between
  46# test cases (but not in the middle of a single test case)
  47#
  48# TEST_START
  49# MIN_CONFIG = /home/test/config-test1
  50#
  51# DEFAULTS
  52# MIN_CONFIG = /home/test/config-default
  53#
  54# TEST_START ITERATE 10
  55#
  56# The above will run the first test with MIN_CONFIG set to
  57# /home/test/config-test-1. Then 10 tests will be executed
  58# with MIN_CONFIG with /home/test/config-default.
  59#
  60# You can also disable defaults with the SKIP option
  61#
  62# DEFAULTS SKIP
  63# MIN_CONFIG = /home/test/config-use-sometimes
  64#
  65# DEFAULTS
  66# MIN_CONFIG = /home/test/config-most-times
  67#
  68# The above will ignore the first MIN_CONFIG. If you want to
  69# use the first MIN_CONFIG, remove the SKIP from the first
  70# DEFAULTS tag and add it to the second. Be careful, options
  71# may only be declared once per test or default. If you have
  72# the same option name under the same test or as default
  73# ktest will fail to execute, and no tests will run.
  74#
  75# DEFAULTS OVERRIDE
  76#
  77# Options defined in the DEFAULTS section can not be duplicated
  78# even if they are defined in two different DEFAULT sections.
  79# This is done to catch mistakes where an option is added but
  80# the previous option was forgotten about and not commented.
  81#
  82# The OVERRIDE keyword can be added to a section to allow this
  83# section to override other DEFAULT sections values that have
  84# been defined previously. It will only override options that
  85# have been defined before its use. Options defined later
  86# in a non override section will still error. The same option
  87# can not be defined in the same section even if that section
  88# is marked OVERRIDE.
  89#
  90#
  91#
  92# Both TEST_START and DEFAULTS sections can also have the IF keyword
  93# The value after the IF must evaluate into a 0 or non 0 positive
  94# integer, and can use the config variables (explained below).
  95#
  96# DEFAULTS IF ${IS_X86_32}
  97#
  98# The above will process the DEFAULTS section if the config
  99# variable IS_X86_32 evaluates to a non zero positive integer
 100# otherwise if it evaluates to zero, it will act the same
 101# as if the SKIP keyword was used.
 102#
 103# The ELSE keyword can be used directly after a section with
 104# a IF statement.
 105#
 106# TEST_START IF ${RUN_NET_TESTS}
 107# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
 108#
 109# ELSE
 110#
 111# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-normal
 112#
 113#
 114# The ELSE keyword can also contain an IF statement to allow multiple
 115# if then else sections. But all the sections must be either
 116# DEFAULT or TEST_START, they can not be a mixture.
 117#
 118# TEST_START IF ${RUN_NET_TESTS}
 119# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
 120#
 121# ELSE IF ${RUN_DISK_TESTS}
 122# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-tests
 123#
 124# ELSE IF ${RUN_CPU_TESTS}
 125# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-cpu
 126#
 127# ELSE
 128# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
 129#
 130# The if statement may also have comparisons that will and for
 131# == and !=, strings may be used for both sides.
 132#
 133# BOX_TYPE := x86_32
 134#
 135# DEFAULTS IF ${BOX_TYPE} == x86_32
 136# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-32
 137# ELSE
 138# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-64
 139#
 140# The DEFINED keyword can be used by the IF statements too.
 141# It returns true if the given config variable or option has been defined
 142# or false otherwise.
 143#
 144# 
 145# DEFAULTS IF DEFINED USE_CC
 146# CC := ${USE_CC}
 147# ELSE
 148# CC := gcc
 149#
 150#
 151# As well as NOT DEFINED.
 152#
 153# DEFAULTS IF NOT DEFINED MAKE_CMD
 154# MAKE_CMD := make ARCH=x86
 155#
 156#
 157# And/or ops (&&,||) may also be used to make complex conditionals.
 158#
 159# TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf
 160#
 161# Notice the use of parentheses. Without any parentheses the above would be
 162# processed the same as:
 163#
 164# TEST_START IF DEFINED ALL_TESTS || (${MYTEST} == boottest && ${MACHINE} == gandalf)
 165#
 166#
 167#
 168# INCLUDE file
 169#
 170# The INCLUDE keyword may be used in DEFAULT sections. This will
 171# read another config file and process that file as well. The included
 172# file can include other files, add new test cases or default
 173# statements. Config variables will be passed to these files and changes
 174# to config variables will be seen by top level config files. Including
 175# a file is processed just like the contents of the file was cut and pasted
 176# into the top level file, except, that include files that end with
 177# TEST_START sections will have that section ended at the end of
 178# the include file. That is, an included file is included followed
 179# by another DEFAULT keyword.
 180#
 181# Unlike other files referenced in this config, the file path does not need
 182# to be absolute. If the file does not start with '/', then the directory
 183# that the current config file was located in is used. If no config by the
 184# given name is found there, then the current directory is searched.
 185#
 186# INCLUDE myfile
 187# DEFAULT
 188#
 189# is the same as:
 190#
 191# INCLUDE myfile
 192#
 193# Note, if the include file does not contain a full path, the file is
 194# searched first by the location of the original include file, and then
 195# by the location that ktest.pl was executed in.
 196#
 197
 198#### Config variables ####
 199#
 200# This config file can also contain "config variables".
 201# These are assigned with ":=" instead of the ktest option
 202# assigment "=".
 203#
 204# The difference between ktest options and config variables
 205# is that config variables can be used multiple times,
 206# where each instance will override the previous instance.
 207# And that they only live at time of processing this config.
 208#
 209# The advantage to config variables are that they can be used
 210# by any option or any other config variables to define thing
 211# that you may use over and over again in the options.
 212#
 213# For example:
 214#
 215# USER      := root
 216# TARGET    := mybox
 217# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test
 218#
 219# TEST_START
 220# MIN_CONFIG = config1
 221# TEST = ${TEST_CASE}
 222#
 223# TEST_START
 224# MIN_CONFIG = config2
 225# TEST = ${TEST_CASE}
 226#
 227# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test2
 228#
 229# TEST_START
 230# MIN_CONFIG = config1
 231# TEST = ${TEST_CASE}
 232#
 233# TEST_START
 234# MIN_CONFIG = config2
 235# TEST = ${TEST_CASE}
 236#
 237# TEST_DIR := /home/me/test
 238#
 239# BUILD_DIR = ${TEST_DIR}/linux.git
 240# OUTPUT_DIR = ${TEST_DIR}/test
 241#
 242# Note, the config variables are evaluated immediately, thus
 243# updating TARGET after TEST_CASE has been assigned does nothing
 244# to TEST_CASE.
 245#
 246# As shown in the example, to evaluate a config variable, you
 247# use the ${X} convention. Simple $X will not work.
 248#
 249# If the config variable does not exist, the ${X} will not
 250# be evaluated. Thus:
 251#
 252# MAKE_CMD = PATH=/mypath:${PATH} make
 253#
 254# If PATH is not a config variable, then the ${PATH} in
 255# the MAKE_CMD option will be evaluated by the shell when
 256# the MAKE_CMD option is passed into shell processing.
 257
 258#### Using options in other options ####
 259#
 260# Options that are defined in the config file may also be used
 261# by other options. All options are evaulated at time of
 262# use (except that config variables are evaluated at config
 263# processing time).
 264#
 265# If an ktest option is used within another option, instead of
 266# typing it again in that option you can simply use the option
 267# just like you can config variables.
 268#
 269# MACHINE = mybox
 270#
 271# TEST = ssh root@${MACHINE} /path/to/test
 272#
 273# The option will be used per test case. Thus:
 274#
 275# TEST_TYPE = test
 276# TEST = ssh root@{MACHINE}
 277#
 278# TEST_START
 279# MACHINE = box1
 280#
 281# TEST_START
 282# MACHINE = box2
 283#
 284# For both test cases, MACHINE will be evaluated at the time
 285# of the test case. The first test will run ssh root@box1
 286# and the second will run ssh root@box2.
 287
 288#### Mandatory Default Options ####
 289
 290# These options must be in the default section, although most
 291# may be overridden by test options.
 292
 293# The machine hostname that you will test
 294#MACHINE = target
 295
 296# The box is expected to have ssh on normal bootup, provide the user
 297#  (most likely root, since you need privileged operations)
 298#SSH_USER = root
 299
 300# The directory that contains the Linux source code
 301#BUILD_DIR = /home/test/linux.git
 302
 303# The directory that the objects will be built
 304# (can not be same as BUILD_DIR)
 305#OUTPUT_DIR = /home/test/build/target
 306
 307# The location of the compiled file to copy to the target
 308# (relative to OUTPUT_DIR)
 309#BUILD_TARGET = arch/x86/boot/bzImage
 310
 311# The place to put your image on the test machine
 312#TARGET_IMAGE = /boot/vmlinuz-test
 313
 314# A script or command to reboot the box
 315#
 316# Here is a digital loggers power switch example
 317#POWER_CYCLE = wget --no-proxy -O /dev/null -q  --auth-no-challenge 'http://admin:admin@power/outlet?5=CCL'
 318#
 319# Here is an example to reboot a virtual box on the current host
 320# with the name "Guest".
 321#POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
 322
 323# The script or command that reads the console
 324#
 325#  If you use ttywatch server, something like the following would work.
 326#CONSOLE = nc -d localhost 3001
 327#
 328# For a virtual machine with guest name "Guest".
 329#CONSOLE =  virsh console Guest
 330
 331# Signal to send to kill console.
 332# ktest.pl will create a child process to monitor the console.
 333# When the console is finished, ktest will kill the child process
 334# with this signal.
 335# (default INT)
 336#CLOSE_CONSOLE_SIGNAL = HUP
 337
 338# Required version ending to differentiate the test
 339# from other linux builds on the system.
 340#LOCALVERSION = -test
 341
 342# For REBOOT_TYPE = grub2, you must specify where the grub.cfg
 343# file is. This is the file that is searched to find the menu
 344# option to boot to with GRUB_REBOOT
 345#GRUB_FILE = /boot/grub2/grub.cfg
 346
 347# The tool for REBOOT_TYPE = grub2 to set the next reboot kernel
 348# to boot into (one shot mode).
 349# (default grub2_reboot)
 350#GRUB_REBOOT = grub2_reboot
 351
 352# The grub title name for the test kernel to boot
 353# (Only mandatory if REBOOT_TYPE = grub or grub2)
 354#
 355# Note, ktest.pl will not update the grub menu.lst, you need to
 356# manually add an option for the test. ktest.pl will search
 357# the grub menu.lst for this option to find what kernel to
 358# reboot into.
 359#
 360# For example, if in the /boot/grub/menu.lst the test kernel title has:
 361# title Test Kernel
 362# kernel vmlinuz-test
 363#
 364# For grub2, a search of top level "menuentry"s are done. No
 365# submenu is searched. The menu is found by searching for the
 366# contents of GRUB_MENU in the line that starts with "menuentry".
 367# You may want to include the quotes around the option. For example:
 368# for: menuentry 'Test Kernel'
 369# do a: GRUB_MENU = 'Test Kernel'
 370# For customizing, add your entry in /etc/grub.d/40_custom.
 371#
 
 
 
 
 372#GRUB_MENU = Test Kernel
 373
 374# For REBOOT_TYPE = syslinux, the name of the syslinux executable
 375# (on the target) to use to set up the next reboot to boot the
 376# test kernel.
 377# (default extlinux)
 378#SYSLINUX = syslinux
 379
 380# For REBOOT_TYPE = syslinux, the path that is passed to to the
 381# syslinux command where syslinux is installed.
 382# (default /boot/extlinux)
 383#SYSLINUX_PATH = /boot/syslinux
 384
 385# For REBOOT_TYPE = syslinux, the syslinux label that references the
 386# test kernel in the syslinux config file.
 387# (default undefined)
 388#SYSLINUX_LABEL = "test-kernel"
 389
 390# A script to reboot the target into the test kernel
 391# This and SWITCH_TO_TEST are about the same, except
 392# SWITCH_TO_TEST is run even for REBOOT_TYPE = grub.
 393# This may be left undefined.

 925#
 926#   IGNORE_WARNINGS can be used to disable the failure of patchcheck

 958#	test	- bad boots but fails a test
 959#
 960# BISECT_GOOD is the commit (SHA1) to label as good (accepts all git good commit types)
 961# BISECT_BAD is the commit to label as bad (accepts all git bad commit types)
 962#
 963# The above three options are required for a bisect operation.
 964#
 965# BISECT_REPLAY = /path/to/replay/file (optional, default undefined)
 966#
 967#   If an operation failed in the bisect that was not expected to
 968#   fail. Then the test ends. The state of the BUILD_DIR will be
 969#   left off at where the failure occurred. You can examine the
 970#   reason for the failure, and perhaps even find a git commit
 971#   that would work to continue with. You can run:
 972#
 973#   git bisect log > /path/to/replay/file
 974#
 975#   The adding:
 976#
 977#    BISECT_REPLAY= /path/to/replay/file
 978#
 979#   And running the test again. The test will perform the initial
 980#    git bisect start, git bisect good, and git bisect bad, and
 981#    then it will run git bisect replay on this file, before
 982#    continuing with the bisect.
 983#
 984# BISECT_START = commit (optional, default undefined)
 985#
 986#   As with BISECT_REPLAY, if the test failed on a commit that
 987#   just happen to have a bad commit in the middle of the bisect,
 988#   and you need to skip it. If BISECT_START is defined, it
 989#   will checkout that commit after doing the initial git bisect start,
 990#   git bisect good, git bisect bad, and running the git bisect replay
 991#   if the BISECT_REPLAY is set.
 992#
 993# BISECT_SKIP = 1 (optional, default 0)
 994#
 995#   If BISECT_TYPE is set to test but the build fails, ktest will
 996#   simply fail the test and end their. You could use BISECT_REPLAY
 997#   and BISECT_START to resume after you found a new starting point,
 998#   or you could set BISECT_SKIP to 1. If BISECT_SKIP is set to 1,
 999#   when something other than the BISECT_TYPE fails, ktest.pl will
1000#   run "git bisect skip" and try again.
1001#
1002# BISECT_FILES = <path> (optional, default undefined)
1003#
1004#   To just run the git bisect on a specific path, set BISECT_FILES.
1005#   For example:
1006#
1007#     BISECT_FILES = arch/x86 kernel/time
1008#
1009#   Will run the bisect with "git bisect start -- arch/x86 kernel/time"
1010#
1011# BISECT_REVERSE = 1 (optional, default 0)
1012#
1013#   In those strange instances where it was broken forever
1014#   and you are trying to find where it started to work!
1015#   Set BISECT_GOOD to the commit that was last known to fail
1016#   Set BISECT_BAD to the commit that is known to start working.
1017#   With BISECT_REVERSE = 1, The test will consider failures as
1018#   good, and success as bad.
1019#
1020# BISECT_MANUAL = 1 (optional, default 0)
1021#
1022#   In case there's a problem with automating the bisect for
1023#   whatever reason. (Can't reboot, want to inspect each iteration)
1024#   Doing a BISECT_MANUAL will have the test wait for you to
1025#   tell it if the test passed or failed after each iteration.
1026#   This is basicall the same as running git bisect yourself
1027#   but ktest will rebuild and install the kernel for you.
1028#
1029# BISECT_CHECK = 1 (optional, default 0)
1030#
1031#   Just to be sure the good is good and bad is bad, setting
1032#   BISECT_CHECK to 1 will start the bisect by first checking
1033#   out BISECT_BAD and makes sure it fails, then it will check
1034#   out BISECT_GOOD and makes sure it succeeds before starting
1035#   the bisect (it works for BISECT_REVERSE too).
1036#
1037#   You can limit the test to just check BISECT_GOOD or
1038#   BISECT_BAD with BISECT_CHECK = good or
1039#   BISECT_CHECK = bad, respectively.
1040#
1041# BISECT_TRIES = 5 (optional, default 1)
1042#
1043#   For those cases that it takes several tries to hit a bug,
1044#   the BISECT_TRIES is useful. It is the number of times the
1045#   test is ran before it says the kernel is good. The first failure
1046#   will stop trying and mark the current SHA1 as bad.
1047#
1048#   Note, as with all race bugs, there's no guarantee that if
1049#   it succeeds, it is really a good bisect. But it helps in case
1050#   the bug is some what reliable.
1051#
1052#   You can set BISECT_TRIES to zero, and all tests will be considered
1053#   good, unless you also set BISECT_MANUAL.
1054#
1055# BISECT_RET_GOOD = 0 (optional, default undefined)
1056#
1057#   In case the specificed test returns something other than just
1058#   0 for good, and non-zero for bad, you can override 0 being
1059#   good by defining BISECT_RET_GOOD.
1060#
1061# BISECT_RET_BAD = 1 (optional, default undefined)
1062#
1063#   In case the specificed test returns something other than just
1064#   0 for good, and non-zero for bad, you can override non-zero being
1065#   bad by defining BISECT_RET_BAD.
1066#
1067# BISECT_RET_ABORT = 255 (optional, default undefined)
1068#
1069#   If you need to abort the bisect if the test discovers something
1070#   that was wrong, you can define BISECT_RET_ABORT to be the error
1071#   code returned by the test in order to abort the bisect.
1072#
1073# BISECT_RET_SKIP = 2 (optional, default undefined)
1074#
1075#   If the test detects that the current commit is neither good
1076#   nor bad, but something else happened (another bug detected)
1077#   you can specify BISECT_RET_SKIP to an error code that the
1078#   test returns when it should skip the current commit.
1079#
1080# BISECT_RET_DEFAULT = good (optional, default undefined)
1081#
1082#   You can override the default of what to do when the above
1083#   options are not hit. This may be one of, "good", "bad",
1084#   "abort" or "skip" (without the quotes).
1085#
1086#   Note, if you do not define any of the previous BISECT_RET_*
1087#   and define BISECT_RET_DEFAULT, all bisects results will do
1088#   what the BISECT_RET_DEFAULT has.
1089#
1090#
1091# Example:
1092#   TEST_START
1093#   TEST_TYPE = bisect
1094#   BISECT_GOOD = v2.6.36
1095#   BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e
1096#   BISECT_TYPE = build
1097#   MIN_CONFIG = /home/test/config-bisect
1098#
1099#
1100#
1101# For TEST_TYPE = config_bisect
1102#
1103#  In those cases that you have two different configs. One of them
1104#  work, the other does not, and you do not know what config causes
1105#  the problem.
1106#  The TEST_TYPE config_bisect will bisect the bad config looking for
1107#  what config causes the failure.
1108#
1109#  The way it works is this:
1110#
1111#   You can specify a good config with CONFIG_BISECT_GOOD, otherwise it
1112#   will use the MIN_CONFIG, and if that's not specified, it will use
1113#   the config that comes with "make defconfig".
1114#
1115#   It runs both the good and bad configs through a make oldconfig to
1116#   make sure that they are set up for the kernel that is checked out.
1117#
1118#   It then reads the configs that are set, as well as the ones that are
1119#   not set for both the good and bad configs, and then compares them.
1120#   It will set half of the good configs within the bad config (note,
1121#   "set" means to make the bad config match the good config, a config
1122#   in the good config that is off, will be turned off in the bad
1123#   config. That is considered a "set").
1124#
1125#   It tests this new config and if it works, it becomes the new good
1126#   config, otherwise it becomes the new bad config. It continues this
1127#   process until there's only one config left and it will report that
1128#   config.
1129#
1130#   The "bad config" can also be a config that is needed to boot but was
1131#   disabled because it depended on something that wasn't set.
1132#
1133#   During this process, it saves the current good and bad configs in
1134#   ${TMP_DIR}/good_config and ${TMP_DIR}/bad_config respectively.
1135#   If you stop the test, you can copy them to a new location to
1136#   reuse them again.
1137#
1138#   Although the MIN_CONFIG may be the config it starts with, the
1139#   MIN_CONFIG is ignored.
1140#
1141#  The option BUILD_TYPE will be ignored.
1142#
1143#  CONFIG_BISECT_TYPE is the type of test to perform:
1144#	build	- bad fails to build
1145#	boot	- bad builds but fails to boot
1146#	test	- bad boots but fails a test
1147#
1148#  CONFIG_BISECT is the config that failed to boot
1149#
1150#  If BISECT_MANUAL is set, it will pause between iterations.
1151#  This is useful to use just ktest.pl just for the config bisect.
1152#  If you set it to build, it will run the bisect and you can
1153#  control what happens in between iterations. It will ask you if
1154#  the test succeeded or not and continue the config bisect.
1155#
1156# CONFIG_BISECT_GOOD (optional)
1157#  If you have a good config to start with, then you
1158#  can specify it with CONFIG_BISECT_GOOD. Otherwise
1159#  the MIN_CONFIG is the base, if MIN_CONFIG is not set
1160#  It will build a config with "make defconfig"
1161#
1162# CONFIG_BISECT_CHECK (optional)
1163#  Set this to 1 if you want to confirm that the config ktest
1164#  generates (the bad config with the min config) is still bad.
1165#  It may be that the min config fixes what broke the bad config
1166#  and the test will not return a result.
1167#  Set it to "good" to test only the good config and set it
1168#  to "bad" to only test the bad config.
 
 
 
 
 
 
 
 
 
 
1169#
1170# Example:
1171#   TEST_START
1172#   TEST_TYPE = config_bisect
1173#   CONFIG_BISECT_TYPE = build
1174#   CONFIG_BISECT = /home/test/config-bad
1175#   MIN_CONFIG = /home/test/config-min
1176#   BISECT_MANUAL = 1
1177#
1178#
1179#
1180# For TEST_TYPE = make_min_config
1181#
1182#  After doing a make localyesconfig, your kernel configuration may
1183#  not be the most useful minimum configuration. Having a true minimum
1184#  config that you can use against other configs is very useful if
1185#  someone else has a config that breaks on your code. By only forcing
1186#  those configurations that are truly required to boot your machine
1187#  will give you less of a chance that one of your set configurations
1188#  will make the bug go away. This will give you a better chance to
1189#  be able to reproduce the reported bug matching the broken config.
1190#
1191#  Note, this does take some time, and may require you to run the
1192#  test over night, or perhaps over the weekend. But it also allows
1193#  you to interrupt it, and gives you the current minimum config
1194#  that was found till that time.
1195#
1196#  Note, this test automatically assumes a BUILD_TYPE of oldconfig
1197#  and its test type acts like boot.
1198#  TODO: add a test version that makes the config do more than just
1199#   boot, like having network access.
1200#
1201#  To save time, the test does not just grab any option and test
1202#  it. The Kconfig files are examined to determine the dependencies
1203#  of the configs. If a config is chosen that depends on another
1204#  config, that config will be checked first. By checking the
1205#  parents first, we can eliminate whole groups of configs that
1206#  may have been enabled.
1207#
1208#  For example, if a USB device config is chosen and depends on CONFIG_USB,
1209#  the CONFIG_USB will be tested before the device. If CONFIG_USB is
1210#  found not to be needed, it, as well as all configs that depend on
1211#  it, will be disabled and removed from the current min_config.
1212#
1213#  OUTPUT_MIN_CONFIG is the path and filename of the file that will
1214#   be created from the MIN_CONFIG. If you interrupt the test, set
1215#   this file as your new min config, and use it to continue the test.
1216#   This file does not need to exist on start of test.
1217#   This file is not created until a config is found that can be removed.
1218#   If this file exists, you will be prompted if you want to use it
1219#   as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG
1220#   is not defined.
1221#   (required field)
1222#
1223#  START_MIN_CONFIG is the config to use to start the test with.
1224#   you can set this as the same OUTPUT_MIN_CONFIG, but if you do
1225#   the OUTPUT_MIN_CONFIG file must exist.
1226#   (default MIN_CONFIG)
1227#
1228#  IGNORE_CONFIG is used to specify a config file that has configs that
1229#   you already know must be set. Configs are written here that have
1230#   been tested and proved to be required. It is best to define this
1231#   file if you intend on interrupting the test and running it where
1232#   it left off. New configs that it finds will be written to this file
1233#   and will not be tested again in later runs.
1234#   (optional)
1235#
1236#  MIN_CONFIG_TYPE can be either 'boot' or 'test'. With 'boot' it will
1237#   test if the created config can just boot the machine. If this is
1238#   set to 'test', then the TEST option must be defined and the created
1239#   config will not only boot the target, but also make sure that the
1240#   config lets the test succeed. This is useful to make sure the final
1241#   config that is generated allows network activity (ssh).
1242#   (optional)
1243#
1244#  USE_OUTPUT_MIN_CONFIG set this to 1 if you do not want to be prompted
1245#   about using the OUTPUT_MIN_CONFIG as the MIN_CONFIG as the starting
1246#   point. Set it to 0 if you want to always just use the given MIN_CONFIG.
1247#   If it is not defined, it will prompt you to pick which config
1248#   to start with (MIN_CONFIG or OUTPUT_MIN_CONFIG).
1249#
1250# Example:
1251#
1252#  TEST_TYPE = make_min_config
1253#  OUTPUT_MIN_CONFIG = /path/to/config-new-min
1254#  START_MIN_CONFIG = /path/to/config-min
1255#  IGNORE_CONFIG = /path/to/config-tested
1256#  MIN_CONFIG_TYPE = test
1257#  TEST = ssh ${USER}@${MACHINE} echo hi
1258#
1259#
1260#
1261#
1262# For TEST_TYPE = make_warnings_file
1263#
1264# If you want the build to fail when a new warning is discovered
1265# you set the WARNINGS_FILE to point to a file of known warnings.
1266#
1267# The test "make_warnings_file" will let you create a new warnings
1268# file before you run other tests, like patchcheck.
1269#
1270# What this test does is to run just a build, you still need to
1271# specify BUILD_TYPE to tell the test what type of config to use.
1272# A BUILD_TYPE of nobuild will fail this test.
1273#
1274# The test will do the build and scan for all warnings. Any warning
1275# it discovers will be saved in the WARNINGS_FILE (required) option.
1276#
1277# It is recommended (but not necessary) to make sure BUILD_NOCLEAN is
1278# off, so that a full build is done (make mrproper is performed).
1279# That way, all warnings will be captured.
1280#
1281# Example:
1282#
1283#  TEST_TYPE = make_warnings_file
1284#  WARNINGS_FILE = ${OUTPUT_DIR}
1285#  BUILD_TYPE = useconfig:oldconfig
1286#  CHECKOUT = v3.8
1287#  BUILD_NOCLEAN = 0
1288#
v5.14.15
   1#
   2# Config file for ktest.pl
   3#
   4# Place your customized version of this, in the working directory that
   5# ktest.pl is run from. By default, ktest.pl will look for a file
   6# called "ktest.conf", but you can name it anything you like and specify
   7# the name of your config file as the first argument of ktest.pl.
   8#
   9# Note, all paths must be absolute
  10#
  11
  12# Options set in the beginning of the file are considered to be
  13# default options. These options can be overridden by test specific
  14# options, with the following exceptions:
  15#
  16#  LOG_FILE
  17#  CLEAR_LOG
  18#  POWEROFF_ON_SUCCESS
  19#  REBOOT_ON_SUCCESS
  20#
  21# Test specific options are set after the label:
  22#
  23# TEST_START
  24#
  25# The options after a TEST_START label are specific to that test.
  26# Each TEST_START label will set up a new test. If you want to
  27# perform a test more than once, you can add the ITERATE label
  28# to it followed by the number of times you want that test
  29# to iterate. If the ITERATE is left off, the test will only
  30# be performed once.
  31#
  32# TEST_START ITERATE 10
  33#
  34# You can skip a test by adding SKIP (before or after the ITERATE
  35# and number)
  36#
  37# TEST_START SKIP
  38#
  39# TEST_START SKIP ITERATE 10
  40#
  41# TEST_START ITERATE 10 SKIP
  42#
  43# The SKIP label causes the options and the test itself to be ignored.
  44# This is useful to set up several different tests in one config file, and
  45# only enabling the ones you want to use for a current test run.
  46#
  47# You can add default options anywhere in the file as well
  48# with the DEFAULTS tag. This allows you to have default options
  49# after the test options to keep the test options at the top
  50# of the file. You can even place the DEFAULTS tag between
  51# test cases (but not in the middle of a single test case)
  52#
  53# TEST_START
  54# MIN_CONFIG = /home/test/config-test1
  55#
  56# DEFAULTS
  57# MIN_CONFIG = /home/test/config-default
  58#
  59# TEST_START ITERATE 10
  60#
  61# The above will run the first test with MIN_CONFIG set to
  62# /home/test/config-test-1. Then 10 tests will be executed
  63# with MIN_CONFIG with /home/test/config-default.
  64#
  65# You can also disable defaults with the SKIP option
  66#
  67# DEFAULTS SKIP
  68# MIN_CONFIG = /home/test/config-use-sometimes
  69#
  70# DEFAULTS
  71# MIN_CONFIG = /home/test/config-most-times
  72#
  73# The above will ignore the first MIN_CONFIG. If you want to
  74# use the first MIN_CONFIG, remove the SKIP from the first
  75# DEFAULTS tag and add it to the second. Be careful, options
  76# may only be declared once per test or default. If you have
  77# the same option name under the same test or as default
  78# ktest will fail to execute, and no tests will run.
  79#
  80# DEFAULTS OVERRIDE
  81#
  82# Options defined in the DEFAULTS section can not be duplicated
  83# even if they are defined in two different DEFAULT sections.
  84# This is done to catch mistakes where an option is added but
  85# the previous option was forgotten about and not commented.
  86#
  87# The OVERRIDE keyword can be added to a section to allow this
  88# section to override other DEFAULT sections values that have
  89# been defined previously. It will only override options that
  90# have been defined before its use. Options defined later
  91# in a non override section will still error. The same option
  92# can not be defined in the same section even if that section
  93# is marked OVERRIDE.
  94#
  95#
  96#
  97# Both TEST_START and DEFAULTS sections can also have the IF keyword
  98# The value after the IF must evaluate into a 0 or non 0 positive
  99# integer, and can use the config variables (explained below).
 100#
 101# DEFAULTS IF ${IS_X86_32}
 102#
 103# The above will process the DEFAULTS section if the config
 104# variable IS_X86_32 evaluates to a non zero positive integer
 105# otherwise if it evaluates to zero, it will act the same
 106# as if the SKIP keyword was used.
 107#
 108# The ELSE keyword can be used directly after a section with
 109# a IF statement.
 110#
 111# TEST_START IF ${RUN_NET_TESTS}
 112# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
 113#
 114# ELSE
 115#
 116# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-normal
 117#
 118#
 119# The ELSE keyword can also contain an IF statement to allow multiple
 120# if then else sections. But all the sections must be either
 121# DEFAULT or TEST_START, they can not be a mixture.
 122#
 123# TEST_START IF ${RUN_NET_TESTS}
 124# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
 125#
 126# ELSE IF ${RUN_DISK_TESTS}

 128#
 129# ELSE IF ${RUN_CPU_TESTS}
 130# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-cpu
 131#
 132# ELSE
 133# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-network
 134#
 135# The if statement may also have comparisons that will and for
 136# == and !=, strings may be used for both sides.
 137#
 138# BOX_TYPE := x86_32
 139#
 140# DEFAULTS IF ${BOX_TYPE} == x86_32
 141# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-32
 142# ELSE
 143# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-64
 144#
 145# The DEFINED keyword can be used by the IF statements too.
 146# It returns true if the given config variable or option has been defined
 147# or false otherwise.
 148#
 149# 
 150# DEFAULTS IF DEFINED USE_CC
 151# CC := ${USE_CC}

 160#
 161#
 162# And/or ops (&&,||) may also be used to make complex conditionals.
 163#
 164# TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf
 165#
 166# Notice the use of parentheses. Without any parentheses the above would be
 167# processed the same as:
 168#
 169# TEST_START IF DEFINED ALL_TESTS || (${MYTEST} == boottest && ${MACHINE} == gandalf)
 170#
 171#
 172#
 173# INCLUDE file
 174#
 175# The INCLUDE keyword may be used in DEFAULT sections. This will
 176# read another config file and process that file as well. The included
 177# file can include other files, add new test cases or default
 178# statements. Config variables will be passed to these files and changes
 179# to config variables will be seen by top level config files. Including
 180# a file is processed just like the contents of the file was cut and pasted
 181# into the top level file, except, that include files that end with
 182# TEST_START sections will have that section ended at the end of
 183# the include file. That is, an included file is included followed
 184# by another DEFAULT keyword.
 185#
 186# Unlike other files referenced in this config, the file path does not need
 187# to be absolute. If the file does not start with '/', then the directory
 188# that the current config file was located in is used. If no config by the
 189# given name is found there, then the current directory is searched.
 190#
 191# INCLUDE myfile
 192# DEFAULT
 193#
 194# is the same as:
 195#
 196# INCLUDE myfile
 197#
 198# Note, if the include file does not contain a full path, the file is
 199# searched first by the location of the original include file, and then
 200# by the location that ktest.pl was executed in.
 201#
 202
 203#### Config variables ####
 204#
 205# This config file can also contain "config variables".
 206# These are assigned with ":=" instead of the ktest option
 207# assignment "=".
 208#
 209# The difference between ktest options and config variables
 210# is that config variables can be used multiple times,
 211# where each instance will override the previous instance.
 212# And that they only live at time of processing this config.
 213#
 214# The advantage to config variables are that they can be used
 215# by any option or any other config variables to define thing
 216# that you may use over and over again in the options.
 217#
 218# For example:
 219#
 220# USER      := root
 221# TARGET    := mybox
 222# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test
 223#
 224# TEST_START
 225# MIN_CONFIG = config1
 226# TEST = ${TEST_CASE}
 227#
 228# TEST_START
 229# MIN_CONFIG = config2
 230# TEST = ${TEST_CASE}
 231#
 232# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test2
 233#
 234# TEST_START
 235# MIN_CONFIG = config1
 236# TEST = ${TEST_CASE}
 237#
 238# TEST_START
 239# MIN_CONFIG = config2
 240# TEST = ${TEST_CASE}
 241#
 242# TEST_DIR := /home/me/test
 243#
 244# BUILD_DIR = ${TEST_DIR}/linux.git
 245# OUTPUT_DIR = ${TEST_DIR}/test
 246#
 247# Note, the config variables are evaluated immediately, thus
 248# updating TARGET after TEST_CASE has been assigned does nothing
 249# to TEST_CASE.
 250#
 251# As shown in the example, to evaluate a config variable, you
 252# use the ${X} convention. Simple $X will not work.
 253#
 254# If the config variable does not exist, the ${X} will not
 255# be evaluated. Thus:
 256#
 257# MAKE_CMD = PATH=/mypath:${PATH} make
 258#
 259# If PATH is not a config variable, then the ${PATH} in
 260# the MAKE_CMD option will be evaluated by the shell when
 261# the MAKE_CMD option is passed into shell processing.
 262
 263#### Using options in other options ####
 264#
 265# Options that are defined in the config file may also be used
 266# by other options. All options are evaluated at time of
 267# use (except that config variables are evaluated at config
 268# processing time).
 269#
 270# If an ktest option is used within another option, instead of
 271# typing it again in that option you can simply use the option
 272# just like you can config variables.
 273#
 274# MACHINE = mybox
 275#
 276# TEST = ssh root@${MACHINE} /path/to/test
 277#
 278# The option will be used per test case. Thus:
 279#
 280# TEST_TYPE = test
 281# TEST = ssh root@{MACHINE}
 282#
 283# TEST_START
 284# MACHINE = box1
 285#
 286# TEST_START
 287# MACHINE = box2
 288#
 289# For both test cases, MACHINE will be evaluated at the time
 290# of the test case. The first test will run ssh root@box1
 291# and the second will run ssh root@box2.
 292

 993#   that git checkout allows (branch name, tag, HEAD~3).
 994#
 995#  PATCHCHECK_END is the last patch to check (default HEAD)

1001#
1002#      Then the changes found will be tested.
1003#
1004#      Note, PATCHCHECK_CHERRY requires PATCHCHECK_END to be defined.
1005#      (default 0)
1006#
1007#  PATCHCHECK_TYPE is required and is the type of test to run:
1008#      build, boot, test.
1009#
1010#   Note, the build test will look for warnings, if a warning occurred
1011#     in a file that a commit touches, the build will fail, unless
1012#     IGNORE_WARNINGS is set for the given commit's sha1
1013#
1014#   IGNORE_WARNINGS can be used to disable the failure of patchcheck
1015#     on a particular commit (SHA1). You can add more than one commit
1016#     by adding a list of SHA1s that are space delimited.
1017#
1018#   If BUILD_NOCLEAN is set, then make mrproper will not be run on

1035# For TEST_TYPE = bisect
1036#
1037#  You can specify a git bisect if the BUILD_DIR is a git repository.
1038#  The MIN_CONFIG will be used for all builds of the bisect. The build type
1039#  used for bisecting is oldconfig.
1040#
1041#  The option BUILD_TYPE will be ignored.
1042#
1043#  BISECT_TYPE is the type of test to perform:
1044#	build	- bad fails to build
1045#	boot	- bad builds but fails to boot
1046#	test	- bad boots but fails a test
1047#
1048# BISECT_GOOD is the commit (SHA1) to label as good (accepts all git good commit types)
1049# BISECT_BAD is the commit to label as bad (accepts all git bad commit types)
1050#
1051# The above three options are required for a bisect operation.
1052#
1053# BISECT_REPLAY = /path/to/replay/file (optional, default undefined)
1054#
1055#   If an operation failed in the bisect that was not expected to
1056#   fail. Then the test ends. The state of the BUILD_DIR will be
1057#   left off at where the failure occurred. You can examine the
1058#   reason for the failure, and perhaps even find a git commit
1059#   that would work to continue with. You can run:
1060#
1061#   git bisect log > /path/to/replay/file
1062#
1063#   The adding:
1064#
1065#    BISECT_REPLAY= /path/to/replay/file
1066#
1067#   And running the test again. The test will perform the initial
1068#    git bisect start, git bisect good, and git bisect bad, and
1069#    then it will run git bisect replay on this file, before
1070#    continuing with the bisect.
1071#
1072# BISECT_START = commit (optional, default undefined)
1073#
1074#   As with BISECT_REPLAY, if the test failed on a commit that
1075#   just happen to have a bad commit in the middle of the bisect,
1076#   and you need to skip it. If BISECT_START is defined, it
1077#   will checkout that commit after doing the initial git bisect start,
1078#   git bisect good, git bisect bad, and running the git bisect replay
1079#   if the BISECT_REPLAY is set.
1080#
1081# BISECT_SKIP = 1 (optional, default 0)
1082#
1083#   If BISECT_TYPE is set to test but the build fails, ktest will
1084#   simply fail the test and end their. You could use BISECT_REPLAY
1085#   and BISECT_START to resume after you found a new starting point,
1086#   or you could set BISECT_SKIP to 1. If BISECT_SKIP is set to 1,
1087#   when something other than the BISECT_TYPE fails, ktest.pl will
1088#   run "git bisect skip" and try again.
1089#
1090# BISECT_FILES = <path> (optional, default undefined)
1091#
1092#   To just run the git bisect on a specific path, set BISECT_FILES.
1093#   For example:
1094#
1095#     BISECT_FILES = arch/x86 kernel/time
1096#
1097#   Will run the bisect with "git bisect start -- arch/x86 kernel/time"
1098#
1099# BISECT_REVERSE = 1 (optional, default 0)
1100#
1101#   In those strange instances where it was broken forever
1102#   and you are trying to find where it started to work!
1103#   Set BISECT_GOOD to the commit that was last known to fail
1104#   Set BISECT_BAD to the commit that is known to start working.
1105#   With BISECT_REVERSE = 1, The test will consider failures as
1106#   good, and success as bad.
1107#
1108# BISECT_MANUAL = 1 (optional, default 0)
1109#
1110#   In case there's a problem with automating the bisect for
1111#   whatever reason. (Can't reboot, want to inspect each iteration)
1112#   Doing a BISECT_MANUAL will have the test wait for you to
1113#   tell it if the test passed or failed after each iteration.
1114#   This is basically the same as running git bisect yourself
1115#   but ktest will rebuild and install the kernel for you.
1116#
1117# BISECT_CHECK = 1 (optional, default 0)
1118#
1119#   Just to be sure the good is good and bad is bad, setting
1120#   BISECT_CHECK to 1 will start the bisect by first checking
1121#   out BISECT_BAD and makes sure it fails, then it will check
1122#   out BISECT_GOOD and makes sure it succeeds before starting
1123#   the bisect (it works for BISECT_REVERSE too).
1124#
1125#   You can limit the test to just check BISECT_GOOD or
1126#   BISECT_BAD with BISECT_CHECK = good or
1127#   BISECT_CHECK = bad, respectively.
1128#
1129# BISECT_TRIES = 5 (optional, default 1)
1130#
1131#   For those cases that it takes several tries to hit a bug,
1132#   the BISECT_TRIES is useful. It is the number of times the
1133#   test is ran before it says the kernel is good. The first failure
1134#   will stop trying and mark the current SHA1 as bad.
1135#
1136#   Note, as with all race bugs, there's no guarantee that if
1137#   it succeeds, it is really a good bisect. But it helps in case
1138#   the bug is some what reliable.
1139#
1140#   You can set BISECT_TRIES to zero, and all tests will be considered
1141#   good, unless you also set BISECT_MANUAL.
1142#
1143# BISECT_RET_GOOD = 0 (optional, default undefined)
1144#
1145#   In case the specificed test returns something other than just
1146#   0 for good, and non-zero for bad, you can override 0 being
1147#   good by defining BISECT_RET_GOOD.
1148#
1149# BISECT_RET_BAD = 1 (optional, default undefined)
1150#
1151#   In case the specificed test returns something other than just
1152#   0 for good, and non-zero for bad, you can override non-zero being
1153#   bad by defining BISECT_RET_BAD.
1154#
1155# BISECT_RET_ABORT = 255 (optional, default undefined)
1156#
1157#   If you need to abort the bisect if the test discovers something
1158#   that was wrong, you can define BISECT_RET_ABORT to be the error
1159#   code returned by the test in order to abort the bisect.
1160#
1161# BISECT_RET_SKIP = 2 (optional, default undefined)
1162#
1163#   If the test detects that the current commit is neither good
1164#   nor bad, but something else happened (another bug detected)
1165#   you can specify BISECT_RET_SKIP to an error code that the
1166#   test returns when it should skip the current commit.
1167#
1168# BISECT_RET_DEFAULT = good (optional, default undefined)
1169#
1170#   You can override the default of what to do when the above
1171#   options are not hit. This may be one of, "good", "bad",
1172#   "abort" or "skip" (without the quotes).
1173#
1174#   Note, if you do not define any of the previous BISECT_RET_*
1175#   and define BISECT_RET_DEFAULT, all bisects results will do
1176#   what the BISECT_RET_DEFAULT has.
1177#
1178#
1179# Example:
1180#   TEST_START
1181#   TEST_TYPE = bisect
1182#   BISECT_GOOD = v2.6.36
1183#   BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e
1184#   BISECT_TYPE = build
1185#   MIN_CONFIG = /home/test/config-bisect
1186#
1187#
1188#
1189# For TEST_TYPE = config_bisect
1190#
1191#  In those cases that you have two different configs. One of them
1192#  work, the other does not, and you do not know what config causes
1193#  the problem.
1194#  The TEST_TYPE config_bisect will bisect the bad config looking for
1195#  what config causes the failure.
1196#
1197#  The way it works is this:
1198#
1199#   You can specify a good config with CONFIG_BISECT_GOOD, otherwise it
1200#   will use the MIN_CONFIG, and if that's not specified, it will use
1201#   the config that comes with "make defconfig".
1202#
1203#   It runs both the good and bad configs through a make oldconfig to
1204#   make sure that they are set up for the kernel that is checked out.
1205#
1206#   It then reads the configs that are set, as well as the ones that are
1207#   not set for both the good and bad configs, and then compares them.
1208#   It will set half of the good configs within the bad config (note,
1209#   "set" means to make the bad config match the good config, a config
1210#   in the good config that is off, will be turned off in the bad
1211#   config. That is considered a "set").
1212#
1213#   It tests this new config and if it works, it becomes the new good
1214#   config, otherwise it becomes the new bad config. It continues this
1215#   process until there's only one config left and it will report that
1216#   config.
1217#
1218#   The "bad config" can also be a config that is needed to boot but was
1219#   disabled because it depended on something that wasn't set.
1220#
1221#   During this process, it saves the current good and bad configs in
1222#   ${TMP_DIR}/good_config and ${TMP_DIR}/bad_config respectively.
1223#   If you stop the test, you can copy them to a new location to
1224#   reuse them again.
1225#
1226#   Although the MIN_CONFIG may be the config it starts with, the
1227#   MIN_CONFIG is ignored.
1228#
1229#  The option BUILD_TYPE will be ignored.
1230#
1231#  CONFIG_BISECT_TYPE is the type of test to perform:
1232#	build	- bad fails to build
1233#	boot	- bad builds but fails to boot
1234#	test	- bad boots but fails a test
1235#
1236#  CONFIG_BISECT is the config that failed to boot
1237#
1238#  If BISECT_MANUAL is set, it will pause between iterations.
1239#  This is useful to use just ktest.pl just for the config bisect.
1240#  If you set it to build, it will run the bisect and you can
1241#  control what happens in between iterations. It will ask you if
1242#  the test succeeded or not and continue the config bisect.
1243#
1244# CONFIG_BISECT_GOOD (optional)
1245#  If you have a good config to start with, then you
1246#  can specify it with CONFIG_BISECT_GOOD. Otherwise
1247#  the MIN_CONFIG is the base, if MIN_CONFIG is not set
1248#  It will build a config with "make defconfig"
1249#
1250# CONFIG_BISECT_CHECK (optional)
1251#  Set this to 1 if you want to confirm that the config ktest
1252#  generates (the bad config with the min config) is still bad.
1253#  It may be that the min config fixes what broke the bad config
1254#  and the test will not return a result.
1255#  Set it to "good" to test only the good config and set it
1256#  to "bad" to only test the bad config.

1258# CONFIG_BISECT_EXEC (optional)
1259#  The config bisect is a separate program that comes with ktest.pl.
1260#  By default, it will look for:
1261#    `pwd`/config-bisect.pl # the location ktest.pl was executed from.
1262#  If it does not find it there, it will look for:
1263#    `dirname <ktest.pl>`/config-bisect.pl # The directory that holds ktest.pl
1264#  If it does not find it there, it will look for:
1265#    ${BUILD_DIR}/tools/testing/ktest/config-bisect.pl
1266#  Setting CONFIG_BISECT_EXEC will override where it looks.
1267#
1268# Example:
1269#   TEST_START
1270#   TEST_TYPE = config_bisect
1271#   CONFIG_BISECT_TYPE = build
1272#   CONFIG_BISECT = /home/test/config-bad
1273#   MIN_CONFIG = /home/test/config-min
1274#   BISECT_MANUAL = 1
1275#
1276#
1277#
1278# For TEST_TYPE = make_min_config
1279#
1280#  After doing a make localyesconfig, your kernel configuration may
1281#  not be the most useful minimum configuration. Having a true minimum
1282#  config that you can use against other configs is very useful if
1283#  someone else has a config that breaks on your code. By only forcing
1284#  those configurations that are truly required to boot your machine
1285#  will give you less of a chance that one of your set configurations
1286#  will make the bug go away. This will give you a better chance to
1287#  be able to reproduce the reported bug matching the broken config.
1288#
1289#  Note, this does take some time, and may require you to run the
1290#  test over night, or perhaps over the weekend. But it also allows
1291#  you to interrupt it, and gives you the current minimum config
1292#  that was found till that time.
1293#
1294#  Note, this test automatically assumes a BUILD_TYPE of oldconfig
1295#  and its test type acts like boot.
1296#  TODO: add a test version that makes the config do more than just
1297#   boot, like having network access.
1298#
1299#  To save time, the test does not just grab any option and test
1300#  it. The Kconfig files are examined to determine the dependencies
1301#  of the configs. If a config is chosen that depends on another
1302#  config, that config will be checked first. By checking the
1303#  parents first, we can eliminate whole groups of configs that
1304#  may have been enabled.
1305#
1306#  For example, if a USB device config is chosen and depends on CONFIG_USB,
1307#  the CONFIG_USB will be tested before the device. If CONFIG_USB is
1308#  found not to be needed, it, as well as all configs that depend on
1309#  it, will be disabled and removed from the current min_config.
1310#
1311#  OUTPUT_MIN_CONFIG is the path and filename of the file that will
1312#   be created from the MIN_CONFIG. If you interrupt the test, set
1313#   this file as your new min config, and use it to continue the test.
1314#   This file does not need to exist on start of test.
1315#   This file is not created until a config is found that can be removed.
1316#   If this file exists, you will be prompted if you want to use it
1317#   as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG
1318#   is not defined.
1319#   (required field)
1320#
1321#  START_MIN_CONFIG is the config to use to start the test with.
1322#   you can set this as the same OUTPUT_MIN_CONFIG, but if you do
1323#   the OUTPUT_MIN_CONFIG file must exist.
1324#   (default MIN_CONFIG)
1325#
1326#  IGNORE_CONFIG is used to specify a config file that has configs that
1327#   you already know must be set. Configs are written here that have
1328#   been tested and proved to be required. It is best to define this
1329#   file if you intend on interrupting the test and running it where
1330#   it left off. New configs that it finds will be written to this file
1331#   and will not be tested again in later runs.
1332#   (optional)
1333#
1334#  MIN_CONFIG_TYPE can be either 'boot' or 'test'. With 'boot' it will
1335#   test if the created config can just boot the machine. If this is
1336#   set to 'test', then the TEST option must be defined and the created
1337#   config will not only boot the target, but also make sure that the
1338#   config lets the test succeed. This is useful to make sure the final
1339#   config that is generated allows network activity (ssh).
1340#   (optional)
1341#
1342#  USE_OUTPUT_MIN_CONFIG set this to 1 if you do not want to be prompted
1343#   about using the OUTPUT_MIN_CONFIG as the MIN_CONFIG as the starting
1344#   point. Set it to 0 if you want to always just use the given MIN_CONFIG.
1345#   If it is not defined, it will prompt you to pick which config
1346#   to start with (MIN_CONFIG or OUTPUT_MIN_CONFIG).
1347#
1348# Example:
1349#
1350#  TEST_TYPE = make_min_config
1351#  OUTPUT_MIN_CONFIG = /path/to/config-new-min
1352#  START_MIN_CONFIG = /path/to/config-min
1353#  IGNORE_CONFIG = /path/to/config-tested
1354#  MIN_CONFIG_TYPE = test
1355#  TEST = ssh ${USER}@${MACHINE} echo hi
1356#
1357#
1358#
1359#
1360# For TEST_TYPE = make_warnings_file
1361#
1362# If you want the build to fail when a new warning is discovered
1363# you set the WARNINGS_FILE to point to a file of known warnings.
1364#
1365# The test "make_warnings_file" will let you create a new warnings
1366# file before you run other tests, like patchcheck.
1367#
1368# What this test does is to run just a build, you still need to
1369# specify BUILD_TYPE to tell the test what type of config to use.
1370# A BUILD_TYPE of nobuild will fail this test.
1371#
1372# The test will do the build and scan for all warnings. Any warning
1373# it discovers will be saved in the WARNINGS_FILE (required) option.
1374#
1375# It is recommended (but not necessary) to make sure BUILD_NOCLEAN is
1376# off, so that a full build is done (make mrproper is performed).
1377# That way, all warnings will be captured.
1378#
1379# Example:
1380#
1381#  TEST_TYPE = make_warnings_file
1382#  WARNINGS_FILE = ${OUTPUT_DIR}
1383#  BUILD_TYPE = useconfig:oldconfig
1384#  CHECKOUT = v3.8
1385#  BUILD_NOCLEAN = 0
1386#
