You can debug someone else's +# .config by only setting the configs in your MIN_CONFIG. The closer +# your MIN_CONFIG is to the true minimum set of configs needed to +# boot your machine, the closer the config you test with will be +# to the users config that had the failure. +# +# The make_min_config test allows you to create a MIN_CONFIG that +# is truly the minimum set of configs needed to boot a box. +# +# In this example, the final config will reside in +# ${CONFIG_DIR}/config-new-min and ${CONFIG_DIR}/config-new-min-net. +# Just move one to the location you have set for MIN_CONFIG. +# +# The first test creates a MIN_CONFIG that will be the minimum +# configuration to boot ${MACHINE} and be able to ssh to it. +# +# The second test creates a MIN_CONFIG that will only boot +# the target and most likely will not let you ssh to it. (Notice +# how the second test uses the first test's result to continue with. +# This is because the second test config is a subset of the first). +# +# The ${CONFIG_DIR}/config-skip (and -net) will hold the configs +# that ktest.pl found would not boot the target without them set. +# The config-new-min holds configs that ktest.pl could not test +# directly because another config that was needed to boot the box +# selected them. Sometimes it is possible that this file will hold +# the true minimum configuration. You can test to see if this is +# the case by running the boot test with BOOT_TYPE = allnoconfig and +# setting setting the MIN_CONFIG to ${CONFIG_DIR}/config-skip. If the +# machine still boots, then you can use the config-skip as your MIN_CONFIG. +# +# These tests can run for several hours (and perhaps days). +# It's OK to kill the test with a Ctrl^C. By restarting without +# modifying this config, ktest.pl will notice that the config-new-min(-net) +# exists, and will use that instead as the starting point. +# The USE_OUTPUT_MIN_CONFIG is set to 1 to keep ktest.pl from asking +# you if you want to use the OUTPUT_MIN_CONFIG as the starting point. +# By using the OUTPUT_MIN_CONFIG as the starting point will allow ktest.pl to +# start almost where it left off. +# +TEST_START IF ${TEST} == min-config +TEST_TYPE = make_min_config +OUTPUT_MIN_CONFIG = ${CONFIG_DIR}/config-new-min-net +IGNORE_CONFIG = ${CONFIG_DIR}/config-skip-net +MIN_CONFIG_TYPE = test +TEST = ${SSH} echo hi +USE_OUTPUT_MIN_CONFIG = 1 + +TEST_START IF ${TEST} == min-config && ${MULTI} +TEST_TYPE = make_min_config +OUTPUT_MIN_CONFIG = ${CONFIG_DIR}/config-new-min +IGNORE_CONFIG = ${CONFIG_DIR}/config-skip +MIN_CONFIG = ${CONFIG_DIR}/config-new-min-net +USE_OUTPUT_MIN_CONFIG = 1 |
