23a57419b3SSteven Rostedt# TEST_START
24a57419b3SSteven Rostedt#
25a57419b3SSteven Rostedt# The options after a TEST_START label are specific to that test.
26a57419b3SSteven Rostedt# Each TEST_START label will set up a new test. If you want to
27a57419b3SSteven Rostedt# perform a test more than once, you can add the ITERATE label
28a57419b3SSteven Rostedt# to it followed by the number of times you want that test
29a57419b3SSteven Rostedt# to iterate. If the ITERATE is left off, the test will only

20377d942ceSSteven Rostedt#### Config variables ####
20477d942ceSSteven Rostedt#
20577d942ceSSteven Rostedt# This config file can also contain "config variables".
20677d942ceSSteven Rostedt# These are assigned with ":=" instead of the ktest option
20777d942ceSSteven Rostedt# assigment "=".
20877d942ceSSteven Rostedt#
20977d942ceSSteven Rostedt# The difference between ktest options and config variables
21077d942ceSSteven Rostedt# is that config variables can be used multiple times,
21177d942ceSSteven Rostedt# where each instance will override the previous instance.
21277d942ceSSteven Rostedt# And that they only live at time of processing this config.
21377d942ceSSteven Rostedt#
21477d942ceSSteven Rostedt# The advantage to config variables are that they can be used
21577d942ceSSteven Rostedt# by any option or any other config variables to define thing
21677d942ceSSteven Rostedt# that you may use over and over again in the options.
21777d942ceSSteven Rostedt#
21877d942ceSSteven Rostedt# For example:
21977d942ceSSteven Rostedt#
22077d942ceSSteven Rostedt# USER      := root
22177d942ceSSteven Rostedt# TARGET    := mybox
22277d942ceSSteven Rostedt# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test
22377d942ceSSteven Rostedt#
22477d942ceSSteven Rostedt# TEST_START
22577d942ceSSteven Rostedt# MIN_CONFIG = config1
22677d942ceSSteven Rostedt# TEST = ${TEST_CASE}
22777d942ceSSteven Rostedt#
22877d942ceSSteven Rostedt# TEST_START
22977d942ceSSteven Rostedt# MIN_CONFIG = config2
23077d942ceSSteven Rostedt# TEST = ${TEST_CASE}
23177d942ceSSteven Rostedt#
23277d942ceSSteven Rostedt# TEST_CASE := ssh ${USER}@${TARGET} /path/to/my/test2
23377d942ceSSteven Rostedt#
23477d942ceSSteven Rostedt# TEST_START
23577d942ceSSteven Rostedt# MIN_CONFIG = config1
23677d942ceSSteven Rostedt# TEST = ${TEST_CASE}
23777d942ceSSteven Rostedt#
23877d942ceSSteven Rostedt# TEST_START
23977d942ceSSteven Rostedt# MIN_CONFIG = config2
24077d942ceSSteven Rostedt# TEST = ${TEST_CASE}

24477d942ceSSteven Rostedt# BUILD_DIR = ${TEST_DIR}/linux.git
24577d942ceSSteven Rostedt# OUTPUT_DIR = ${TEST_DIR}/test
24677d942ceSSteven Rostedt#
24777d942ceSSteven Rostedt# Note, the config variables are evaluated immediately, thus
24877d942ceSSteven Rostedt# updating TARGET after TEST_CASE has been assigned does nothing
24977d942ceSSteven Rostedt# to TEST_CASE.
25077d942ceSSteven Rostedt#
25177d942ceSSteven Rostedt# As shown in the example, to evaluate a config variable, you
25277d942ceSSteven Rostedt# use the ${X} convention. Simple $X will not work.
25377d942ceSSteven Rostedt#
25477d942ceSSteven Rostedt# If the config variable does not exist, the ${X} will not
25577d942ceSSteven Rostedt# be evaluated. Thus:
25677d942ceSSteven Rostedt#
25777d942ceSSteven Rostedt# MAKE_CMD = PATH=/mypath:${PATH} make
25877d942ceSSteven Rostedt#
25977d942ceSSteven Rostedt# If PATH is not a config variable, then the ${PATH} in
26077d942ceSSteven Rostedt# the MAKE_CMD option will be evaluated by the shell when
26177d942ceSSteven Rostedt# the MAKE_CMD option is passed into shell processing.
262a57419b3SSteven Rostedt
2632a62512bSSteven Rostedt#### Using options in other options ####
2642a62512bSSteven Rostedt#
2652a62512bSSteven Rostedt# Options that are defined in the config file may also be used
2662a62512bSSteven Rostedt# by other options. All options are evaulated at time of
2672a62512bSSteven Rostedt# use (except that config variables are evaluated at config
2682a62512bSSteven Rostedt# processing time).
2692a62512bSSteven Rostedt#
2702a62512bSSteven Rostedt# If an ktest option is used within another option, instead of
2712a62512bSSteven Rostedt# typing it again in that option you can simply use the option
2722a62512bSSteven Rostedt# just like you can config variables.
2732a62512bSSteven Rostedt#
2742a62512bSSteven Rostedt# MACHINE = mybox
2752a62512bSSteven Rostedt#

2772a62512bSSteven Rostedt#
2782a62512bSSteven Rostedt# The option will be used per test case. Thus:

2892a62512bSSteven Rostedt# For both test cases, MACHINE will be evaluated at the time

1213b9066f6cSSteven Rostedt#  To save time, the test does not just grab any option and test
1214b9066f6cSSteven Rostedt#  it. The Kconfig files are examined to determine the dependencies
1215b9066f6cSSteven Rostedt#  of the configs. If a config is chosen that depends on another
1216b9066f6cSSteven Rostedt#  config, that config will be checked first. By checking the
1217b9066f6cSSteven Rostedt#  parents first, we can eliminate whole groups of configs that
1218b9066f6cSSteven Rostedt#  may have been enabled.
1219b9066f6cSSteven Rostedt#
1220b9066f6cSSteven Rostedt#  For example, if a USB device config is chosen and depends on CONFIG_USB,
1221b9066f6cSSteven Rostedt#  the CONFIG_USB will be tested before the device. If CONFIG_USB is
1222b9066f6cSSteven Rostedt#  found not to be needed, it, as well as all configs that depend on
1223b9066f6cSSteven Rostedt#  it, will be disabled and removed from the current min_config.

12254c4ab120SSteven Rostedt#  OUTPUT_MIN_CONFIG is the path and filename of the file that will
12264c4ab120SSteven Rostedt#   be created from the MIN_CONFIG. If you interrupt the test, set
12274c4ab120SSteven Rostedt#   this file as your new min config, and use it to continue the test.
12284c4ab120SSteven Rostedt#   This file does not need to exist on start of test.
12294c4ab120SSteven Rostedt#   This file is not created until a config is found that can be removed.

12394c4ab120SSteven Rostedt#
12404c4ab120SSteven Rostedt#  IGNORE_CONFIG is used to specify a config file that has configs that
12414c4ab120SSteven Rostedt#   you already know must be set. Configs are written here that have
12424c4ab120SSteven Rostedt#   been tested and proved to be required. It is best to define this
12434c4ab120SSteven Rostedt#   file if you intend on interrupting the test and running it where
12444c4ab120SSteven Rostedt#   it left off. New configs that it finds will be written to this file
12454c4ab120SSteven Rostedt#   and will not be tested again in later runs.

1251ccc513b6SSteven Rostedt#   config will not only boot the target, but also make sure that the
