2 # This file has some examples for creating a MIN_CONFIG.
3 # (A .config file that is the minimum for a machine to boot, or
4 # to boot and make a network connection.)
6 # A MIN_CONFIG is very useful as it is the minimum configuration
7 # needed to boot a given machine. You can debug someone else's
8 # .config by only setting the configs in your MIN_CONFIG. The closer
9 # your MIN_CONFIG is to the true minimum set of configs needed to
10 # boot your machine, the closer the config you test with will be
11 # to the users config that had the failure.
13 # The make_min_config test allows you to create a MIN_CONFIG that
14 # is truly the minimum set of configs needed to boot a box.
16 # In this example, the final config will reside in
17 # ${CONFIG_DIR}/config-new-min and ${CONFIG_DIR}/config-new-min-net.
18 # Just move one to the location you have set for MIN_CONFIG.
20 # The first test creates a MIN_CONFIG that will be the minimum
21 # configuration to boot ${MACHINE} and be able to ssh to it.
23 # The second test creates a MIN_CONFIG that will only boot
24 # the target and most likely will not let you ssh to it. (Notice
25 # how the second test uses the first test's result to continue with.
26 # This is because the second test config is a subset of the first).
28 # The ${CONFIG_DIR}/config-skip (and -net) will hold the configs
29 # that ktest.pl found would not boot the target without them set.
30 # The config-new-min holds configs that ktest.pl could not test
31 # directly because another config that was needed to boot the box
32 # selected them. Sometimes it is possible that this file will hold
33 # the true minimum configuration. You can test to see if this is
34 # the case by running the boot test with BOOT_TYPE = allnoconfig and
35 # setting setting the MIN_CONFIG to ${CONFIG_DIR}/config-skip. If the
36 # machine still boots, then you can use the config-skip as your MIN_CONFIG.
38 # These tests can run for several hours (and perhaps days).
39 # It's OK to kill the test with a Ctrl^C. By restarting without
40 # modifying this config, ktest.pl will notice that the config-new-min(-net)
41 # exists, and will use that instead as the starting point.
42 # The USE_OUTPUT_MIN_CONFIG is set to 1 to keep ktest.pl from asking
43 # you if you want to use the OUTPUT_MIN_CONFIG as the starting point.
44 # By using the OUTPUT_MIN_CONFIG as the starting point will allow ktest.pl to
45 # start almost where it left off.
