12 # Compares a good config to a bad config, then takes half of the diffs
13 # and produces a config that is somewhere between the good config and
14 # the bad config. That is, the resulting config will start with the
15 # good config and will try to make half of the differences of between
16 # the good and bad configs match the bad config. It tries because of
18 # exactly half of the configs that are different between the two config
24 # $ config-bisect.pl /path/to/good/config /path/to/bad/config
26 # This will now pull in good config (blowing away .config in that directory
28 # build the config with "make oldconfig" to make sure it matches the
30 # the good config. It does the same for the bad config as well.
34 # It then copies the result of its good config to /path/to/good/config.tmp
35 # and the bad config to /path/to/bad/config.tmp (just appends ".tmp" to the
36 # files passed in). And the ".config" that you should test will be in
43 # $ config-bisect.pl /path/to/good/config /path/to/bad/config good
46 # $ config-bisect.pl /path/to/good/config /path/to/bad/config bad
48 # Do not change the good-config or bad-config, config-bisect.pl will
49 # copy the good-config to a temp file with the same name as good-config
50 # but with a ".tmp" after it. It will do the same with the bad-config.
55 # If the last config is labeled "good", then it will copy it to the good .tmp
56 # version. If the last config is labeled "bad", it will copy it to the bad
