# # This file has some examples for creating a MIN_CONFIG. # (A .config file that is the minimum for a machine to boot, or # to boot and make a network connection.) # # A MIN_CONFIG is very useful as it is the minimum configuration # needed to boot a given machine. 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 |
