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
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
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
27 # so do not make that be one of the good or bad configs), and then
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
39 # After the first run, determine if the result is good or bad then
42 # For good results:
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
52 # If "good" or "bad" is not stated at the end, it will copy the good and
55 # If the last config is labeled "good", then it will copy it to the good .tmp
58 # without the result being equal to either the good or bad .tmp configs.
74 usage: config-bisect.pl [-l linux-tree][-b build-dir] good-config bad-config [good|bad]
77   good-config the config that is considered good
79   "good" add this if the last run produced a good config
81   If "good" or "bad" is not specified, then it is the start of a new bisect
83   Note, each run will create copy of good and bad configs with ".tmp" appended.
