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 overriden 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 ${RUN_DISK_TESTS}
127# BUILD_TYPE = useconfig:${CONFIG_DIR}/config-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}
152# ELSE
153# CC := gcc
154#
155#
156# As well as NOT DEFINED.
157#
158# DEFAULTS IF NOT DEFINED MAKE_CMD
159# MAKE_CMD := make ARCH=x86
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# assigment "=".
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 ${PATH} in
260# the MAKE_CMD option will be evaluated by the shell when
261# the MAKE_CMD option is passed into shell processing.
262
263#### Using options in other options ####
264#
265# Options that are defined in the config file may also be used
266# by other options. All options are evaulated at time of
267# use (except that config variables are evaluated at config
268# processing time).
269#
270# If an ktest option is used within another option, instead of
271# typing it again in that option you can simply use the option
272# just like you can config variables.
273#
274# MACHINE = mybox
275#
276# TEST = ssh root@${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
304
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
339# with this signal.
340# (default INT)
341#CLOSE_CONSOLE_SIGNAL = HUP
342
343# Required version ending to differentiate the test
344# from other linux builds on the system.
345#LOCALVERSION = -test
346
347# For REBOOT_TYPE = grub2, you must specify where the grub.cfg
348# file is. This is the file that is searched to find the menu
349# option to boot to with GRUB_REBOOT
350#GRUB_FILE = /boot/grub2/grub.cfg

352# The tool for REBOOT_TYPE = grub2 to set the next reboot kernel
353# to boot into (one shot mode).
354# (default grub2_reboot)
355#GRUB_REBOOT = grub2_reboot
356
357# The grub title name for the test kernel to boot
358# (Only mandatory if REBOOT_TYPE = grub or grub2)
359#
360# Note, ktest.pl will not update the grub menu.lst, you need to
361# manually add an option for the test. ktest.pl will search
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:
366# title Test Kernel
367# kernel vmlinuz-test
368#
369# For grub2, a search of top level "menuentry"s are done. No
370# submenu is searched. The menu is found by searching for the
371# contents of GRUB_MENU in the line that starts with "menuentry".
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'
375# For customizing, add your entry in /etc/grub.d/40_custom.
376#
377#GRUB_MENU = Test Kernel
378
379# For REBOOT_TYPE = syslinux, the name of the syslinux executable
380# (on the target) to use to set up the next reboot to boot the
381# test kernel.
382# (default extlinux)
383#SYSLINUX = syslinux
384
385# For REBOOT_TYPE = syslinux, the path that is passed to to the
386# syslinux command where syslinux is installed.

388#SYSLINUX_PATH = /boot/syslinux
389
390# For REBOOT_TYPE = syslinux, the syslinux label that references the

394
395# A script to reboot the target into the test kernel
396# This and SWITCH_TO_TEST are about the same, except
397# SWITCH_TO_TEST is run even for REBOOT_TYPE = grub.

423# ktest.pl will do the substitution for MAIL_PATH, MAILER, MAILTO at the time
424#    it sends the mail if "$FOO" format is used. If "${FOO}" format is used,
425#    then the substitutions will occur at the time the config file is read.

1065#   Set BISECT_GOOD to the commit that was last known to fail
1066#   Set BISECT_BAD to the commit that is known to start working.
1067#   With BISECT_REVERSE = 1, The test will consider failures as
1068#   good, and success as bad.
1069#
1070# BISECT_MANUAL = 1 (optional, default 0)
1071#
1072#   In case there's a problem with automating the bisect for
1073#   whatever reason. (Can't reboot, want to inspect each iteration)
1074#   Doing a BISECT_MANUAL will have the test wait for you to
1075#   tell it if the test passed or failed after each iteration.
1076#   This is basicall the same as running git bisect yourself
1077#   but ktest will rebuild and install the kernel for you.
1078#
1079# BISECT_CHECK = 1 (optional, default 0)
1080#
1081#   Just to be sure the good is good and bad is bad, setting
1082#   BISECT_CHECK to 1 will start the bisect by first checking
1083#   out BISECT_BAD and makes sure it fails, then it will check
1084#   out BISECT_GOOD and makes sure it succeeds before starting
1085#   the bisect (it works for BISECT_REVERSE too).
1086#
1087#   You can limit the test to just check BISECT_GOOD or
1088#   BISECT_BAD with BISECT_CHECK = good or
1089#   BISECT_CHECK = bad, respectively.
1090#
1091# BISECT_TRIES = 5 (optional, default 1)
1092#
1093#   For those cases that it takes several tries to hit a bug,
1094#   the BISECT_TRIES is useful. It is the number of times the
1095#   test is ran before it says the kernel is good. The first failure
1096#   will stop trying and mark the current SHA1 as bad.
1097#
1098#   Note, as with all race bugs, there's no guarantee that if
1099#   it succeeds, it is really a good bisect. But it helps in case
1100#   the bug is some what reliable.
1101#
1102#   You can set BISECT_TRIES to zero, and all tests will be considered
1103#   good, unless you also set BISECT_MANUAL.
1104#
1105# BISECT_RET_GOOD = 0 (optional, default undefined)
1106#
1107#   In case the specificed test returns something other than just
1108#   0 for good, and non-zero for bad, you can override 0 being
1109#   good by defining BISECT_RET_GOOD.
1110#
1111# BISECT_RET_BAD = 1 (optional, default undefined)
1112#
1113#   In case the specificed test returns something other than just
1114#   0 for good, and non-zero for bad, you can override non-zero being
1115#   bad by defining BISECT_RET_BAD.
1116#
1117# BISECT_RET_ABORT = 255 (optional, default undefined)
1118#
1119#   If you need to abort the bisect if the test discovers something
1120#   that was wrong, you can define BISECT_RET_ABORT to be the error
1121#   code returned by the test in order to abort the bisect.
1122#
1123# BISECT_RET_SKIP = 2 (optional, default undefined)
1124#
1125#   If the test detects that the current commit is neither good
1126#   nor bad, but something else happened (another bug detected)
1127#   you can specify BISECT_RET_SKIP to an error code that the
1128#   test returns when it should skip the current commit.
1129#
1130# BISECT_RET_DEFAULT = good (optional, default undefined)
1131#
1132#   You can override the default of what to do when the above
1133#   options are not hit. This may be one of, "good", "bad",
1134#   "abort" or "skip" (without the quotes).
1135#
1136#   Note, if you do not define any of the previous BISECT_RET_*
1137#   and define BISECT_RET_DEFAULT, all bisects results will do
1138#   what the BISECT_RET_DEFAULT has.
1139#
1140#
1141# Example:
1142#   TEST_START
1143#   TEST_TYPE = bisect
1144#   BISECT_GOOD = v2.6.36
1145#   BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e
1146#   BISECT_TYPE = build
1147#   MIN_CONFIG = /home/test/config-bisect
1148#
1149#
1150#
1151# For TEST_TYPE = config_bisect
1152#
1153#  In those cases that you have two different configs. One of them
1154#  work, the other does not, and you do not know what config causes
1155#  the problem.
1156#  The TEST_TYPE config_bisect will bisect the bad config looking for
1157#  what config causes the failure.
1158#
1159#  The way it works is this:
1160#
1161#   You can specify a good config with CONFIG_BISECT_GOOD, otherwise it
1162#   will use the MIN_CONFIG, and if that's not specified, it will use
1163#   the config that comes with "make defconfig".
1164#
1165#   It runs both the good and bad configs through a make oldconfig to
1166#   make sure that they are set up for the kernel that is checked out.
1167#
1168#   It then reads the configs that are set, as well as the ones that are
1169#   not set for both the good and bad configs, and then compares them.
1170#   It will set half of the good configs within the bad config (note,
1171#   "set" means to make the bad config match the good config, a config
1172#   in the good config that is off, will be turned off in the bad
1173#   config. That is considered a "set").
1174#
1175#   It tests this new config and if it works, it becomes the new good
1176#   config, otherwise it becomes the new bad config. It continues this
1177#   process until there's only one config left and it will report that
1178#   config.
1179#
1180#   The "bad config" can also be a config that is needed to boot but was
1181#   disabled because it depended on something that wasn't set.
1182#
1183#   During this process, it saves the current good and bad configs in
1184#   ${TMP_DIR}/good_config and ${TMP_DIR}/bad_config respectively.
1185#   If you stop the test, you can copy them to a new location to
1186#   reuse them again.
1187#
1188#   Although the MIN_CONFIG may be the config it starts with, the
1189#   MIN_CONFIG is ignored.
1190#
1191#  The option BUILD_TYPE will be ignored.
1192#
1193#  CONFIG_BISECT_TYPE is the type of test to perform:
1194#	build	- bad fails to build
1195#	boot	- bad builds but fails to boot
1196#	test	- bad boots but fails a test
1197#
1198#  CONFIG_BISECT is the config that failed to boot
1199#
1200#  If BISECT_MANUAL is set, it will pause between iterations.
1201#  This is useful to use just ktest.pl just for the config bisect.
1202#  If you set it to build, it will run the bisect and you can
1203#  control what happens in between iterations. It will ask you if
1204#  the test succeeded or not and continue the config bisect.
1205#
1206# CONFIG_BISECT_GOOD (optional)
1207#  If you have a good config to start with, then you
1208#  can specify it with CONFIG_BISECT_GOOD. Otherwise
1209#  the MIN_CONFIG is the base, if MIN_CONFIG is not set
1210#  It will build a config with "make defconfig"
1211#
1212# CONFIG_BISECT_CHECK (optional)
1213#  Set this to 1 if you want to confirm that the config ktest
1214#  generates (the bad config with the min config) is still bad.
1215#  It may be that the min config fixes what broke the bad config
1216#  and the test will not return a result.
1217#  Set it to "good" to test only the good config and set it
1218#  to "bad" to only test the bad config.
1219#
1220# CONFIG_BISECT_EXEC (optional)
1221#  The config bisect is a separate program that comes with ktest.pl.
1222#  By befault, it will look for:
1223#    `pwd`/config-bisect.pl # the location ktest.pl was executed from.
1224#  If it does not find it there, it will look for:
1225#    `dirname <ktest.pl>`/config-bisect.pl # The directory that holds ktest.pl
1226#  If it does not find it there, it will look for:
1227#    ${BUILD_DIR}/tools/testing/ktest/config-bisect.pl
1228#  Setting CONFIG_BISECT_EXEC will override where it looks.
1229#
1230# Example:
1231#   TEST_START
1232#   TEST_TYPE = config_bisect
1233#   CONFIG_BISECT_TYPE = build
1234#   CONFIG_BISECT = /home/test/config-bad
1235#   MIN_CONFIG = /home/test/config-min
1236#   BISECT_MANUAL = 1
1237#
1238#
1239#
1240# For TEST_TYPE = make_min_config
1241#
1242#  After doing a make localyesconfig, your kernel configuration may
1243#  not be the most useful minimum configuration. Having a true minimum
1244#  config that you can use against other configs is very useful if
1245#  someone else has a config that breaks on your code. By only forcing
1246#  those configurations that are truly required to boot your machine
1247#  will give you less of a chance that one of your set configurations
1248#  will make the bug go away. This will give you a better chance to
1249#  be able to reproduce the reported bug matching the broken config.
1250#
1251#  Note, this does take some time, and may require you to run the
1252#  test over night, or perhaps over the weekend. But it also allows
1253#  you to interrupt it, and gives you the current minimum config
1254#  that was found till that time.
1255#
1256#  Note, this test automatically assumes a BUILD_TYPE of oldconfig
1257#  and its test type acts like boot.
1258#  TODO: add a test version that makes the config do more than just
1259#   boot, like having network access.
1260#
1261#  To save time, the test does not just grab any option and test
1262#  it. The Kconfig files are examined to determine the dependencies
1263#  of the configs. If a config is chosen that depends on another
1264#  config, that config will be checked first. By checking the
1265#  parents first, we can eliminate whole groups of configs that
1266#  may have been enabled.
1267#
1268#  For example, if a USB device config is chosen and depends on CONFIG_USB,
1269#  the CONFIG_USB will be tested before the device. If CONFIG_USB is
1270#  found not to be needed, it, as well as all configs that depend on
1271#  it, will be disabled and removed from the current min_config.
1272#
1273#  OUTPUT_MIN_CONFIG is the path and filename of the file that will
1274#   be created from the MIN_CONFIG. If you interrupt the test, set
1275#   this file as your new min config, and use it to continue the test.
1276#   This file does not need to exist on start of test.
1277#   This file is not created until a config is found that can be removed.
1278#   If this file exists, you will be prompted if you want to use it
1279#   as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG
1280#   is not defined.
1281#   (required field)
1282#
1283#  START_MIN_CONFIG is the config to use to start the test with.
1284#   you can set this as the same OUTPUT_MIN_CONFIG, but if you do
1285#   the OUTPUT_MIN_CONFIG file must exist.
1286#   (default MIN_CONFIG)
1287#
1288#  IGNORE_CONFIG is used to specify a config file that has configs that
1289#   you already know must be set. Configs are written here that have
1290#   been tested and proved to be required. It is best to define this
1291#   file if you intend on interrupting the test and running it where
1292#   it left off. New configs that it finds will be written to this file
1293#   and will not be tested again in later runs.
1294#   (optional)
1295#
1296#  MIN_CONFIG_TYPE can be either 'boot' or 'test'. With 'boot' it will
1297#   test if the created config can just boot the machine. If this is
1298#   set to 'test', then the TEST option must be defined and the created
1299#   config will not only boot the target, but also make sure that the
1300#   config lets the test succeed. This is useful to make sure the final
1301#   config that is generated allows network activity (ssh).
1302#   (optional)
1303#
1304#  USE_OUTPUT_MIN_CONFIG set this to 1 if you do not want to be prompted
1305#   about using the OUTPUT_MIN_CONFIG as the MIN_CONFIG as the starting
1306#   point. Set it to 0 if you want to always just use the given MIN_CONFIG.
1307#   If it is not defined, it will prompt you to pick which config
1308#   to start with (MIN_CONFIG or OUTPUT_MIN_CONFIG).
1309#
1310# Example:
1311#
1312#  TEST_TYPE = make_min_config
1313#  OUTPUT_MIN_CONFIG = /path/to/config-new-min
1314#  START_MIN_CONFIG = /path/to/config-min
1315#  IGNORE_CONFIG = /path/to/config-tested
1316#  MIN_CONFIG_TYPE = test
1317#  TEST = ssh ${USER}@${MACHINE} echo hi
1318#
1319#
1320#
1321#
1322# For TEST_TYPE = make_warnings_file
1323#
1324# If you want the build to fail when a new warning is discovered
1325# you set the WARNINGS_FILE to point to a file of known warnings.
1326#
1327# The test "make_warnings_file" will let you create a new warnings
1328# file before you run other tests, like patchcheck.
1329#
1330# What this test does is to run just a build, you still need to
1331# specify BUILD_TYPE to tell the test what type of config to use.
1332# A BUILD_TYPE of nobuild will fail this test.
1333#
1334# The test will do the build and scan for all warnings. Any warning
1335# it discovers will be saved in the WARNINGS_FILE (required) option.
1336#
1337# It is recommended (but not necessary) to make sure BUILD_NOCLEAN is
1338# off, so that a full build is done (make mrproper is performed).
1339# That way, all warnings will be captured.
1340#
1341# Example:
1342#
1343#  TEST_TYPE = make_warnings_file
1344#  WARNINGS_FILE = ${OUTPUT_DIR}
1345#  BUILD_TYPE = useconfig:oldconfig
1346#  CHECKOUT = v3.8
1347#  BUILD_NOCLEAN = 0
1348#
