      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#

    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

    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#

    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
    293#### Mandatory Default Options ####
    294
    295# These options must be in the default section, although most
    296# may be overridden by test options.
    297
    298# The machine hostname that you will test
    299#MACHINE = target
    300
    301# The box is expected to have ssh on normal bootup, provide the user
    302#  (most likely root, since you need privileged operations)
    303#SSH_USER = root

    305# The directory that contains the Linux source code
    306#BUILD_DIR = /home/test/linux.git
    307
    308# The directory that the objects will be built
    309# (can not be same as BUILD_DIR)
    310#OUTPUT_DIR = /home/test/build/target
    311
    312# The location of the compiled file to copy to the target
    313# (relative to OUTPUT_DIR)
    314#BUILD_TARGET = arch/x86/boot/bzImage
    315
    316# The place to put your image on the test machine
    317#TARGET_IMAGE = /boot/vmlinuz-test
    318
    319# A script or command to reboot the box
    320#
    321# Here is a digital loggers power switch example
    322#POWER_CYCLE = wget --no-proxy -O /dev/null -q  --auth-no-challenge 'http://admin:admin@power/outlet?5=CCL'
    323#
    324# Here is an example to reboot a virtual box on the current host
    325# with the name "Guest".
    326#POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
    327
    328# The script or command that reads the console
    329#
    330#  If you use ttywatch server, something like the following would work.
    331#CONSOLE = nc -d localhost 3001
    332#
    333# For a virtual machine with guest name "Guest".
    334#CONSOLE =  virsh console Guest
    335
    336# Signal to send to kill console.
    337# ktest.pl will create a child process to monitor the console.
    338# When the console is finished, ktest will kill the child process

    362# the grub menu.lst for this option to find what kernel to
    363# reboot into.
    364#
    365# For example, if in the /boot/grub/menu.lst the test kernel title has:

    372# You may want to include the quotes around the option. For example:
    373# for: menuentry 'Test Kernel'
    374# do a: GRUB_MENU = 'Test Kernel'

    966# CHECKOUT = branch
    967#
    968#  If the BUILD_DIR is a git repository, then you can set this option

   1005#      (default 0)
   1006#
   1007#  PATCHCHECK_TYPE is required and is the type of test to run:

   1009#
   1010#   Note, the build test will look for warnings, if a warning occurred

   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

   1021#   BUILD_NOCLEAN is not set, only the first and last patch run
   1022#   make mrproper. This helps speed up the test.
   1023#

   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.
   1257#
   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#
