Steven Rostedta57419b2010-11-02 15:13:54 -040016# 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#
Steven Rostedt3d1cc412011-09-30 22:14:21 -040075# 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.

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

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.

Steven Rostedt77d942c2011-05-20 13:36:58 -0400198#### 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 ${PATH} in
255# the MAKE_CMD option will be evaluated by the shell when
256# the MAKE_CMD option is passed into shell processing.
Steven Rostedta57419b2010-11-02 15:13:54 -0400257
Steven Rostedt2a625122011-05-20 15:48:59 -0400258#### Using options in other options ####
259#
260# Options that are defined in the config file may also be used
261# by other options. All options are evaulated at time of
262# use (except that config variables are evaluated at config
263# processing time).
264#
265# If an ktest option is used within another option, instead of
266# typing it again in that option you can simply use the option
267# just like you can config variables.
268#
269# MACHINE = mybox
270#
271# TEST = ssh root@${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
Steven Rostedta57419b2010-11-02 15:13:54 -0400288#### Mandatory Default Options ####
289
290# These options must be in the default section, although most

1041# The TEST_TYPE config_bisect will bisect the bad config looking for
1042# what config causes the failure.
1043#
1044# The way it works is this:
1045#
1046# First it finds a config to work with. Since a different version, or
1047# MIN_CONFIG may cause different dependecies, it must run through this
1048# preparation.
1049#
1050# Overwrites any config set in the bad config with a config set in
1051# either the MIN_CONFIG or ADD_CONFIG. Thus, make sure these configs
1052# are minimal and do not disable configs you want to test:
1053# (ie. # CONFIG_FOO is not set).
1054#
1055# An oldconfig is run on the bad config and any new config that
1056# appears will be added to the configs to test.
1057#
1058# Finally, it generates a config with the above result and runs it
1059# again through make oldconfig to produce a config that should be
1060# satisfied by kconfig.
1061#
1062# Then it starts the bisect.
1063#
1064# The configs to test are cut in half. If all the configs in this
1065# half depend on a config in the other half, then the other half
1066# is tested instead. If no configs are enabled by either half, then
1067# this means a circular dependency exists and the test fails.
1068#
1069# A config is created with the test half, and the bisect test is run.
1070#
1071# If the bisect succeeds, then all configs in the generated config
1072# are removed from the configs to test and added to the configs that
1073# will be enabled for all builds (they will be enabled, but not be part

1075#
1076# If the bisect fails, then all test configs that were not enabled by
1077# the config file are removed from the test. These configs will not
1078# be enabled in future tests. Since current config failed, we consider
1079# this to be a subset of the config that we started with.
1080#
1081# When we are down to one config, it is considered the bad config.
1082#
1083# Note, the config chosen may not be the true bad config. Due to
1084# dependencies and selections of the kbuild system, mulitple
1085# configs may be needed to cause a failure. If you disable the
1086# config that was found and restart the test, if the test fails

Steven Rostedtb9066f62011-07-15 21:25:24 -04001147# To save time, the test does not just grab any option and test
