# The way it works is this:
#
-# First it finds a config to work with. Since a different version, or
-# MIN_CONFIG may cause different dependecies, it must run through this
-# preparation.
+# You can specify a good config with CONFIG_BISECT_GOOD, otherwise it
+# will use the MIN_CONFIG, and if that's not specified, it will use
+# the config that comes with "make defconfig".
#
-# Overwrites any config set in the bad config with a config set in
-# either the MIN_CONFIG or ADD_CONFIG. Thus, make sure these configs
-# are minimal and do not disable configs you want to test:
-# (ie. # CONFIG_FOO is not set).
+# It runs both the good and bad configs through a make oldconfig to
+# make sure that they are set up for the kernel that is checked out.
#
-# An oldconfig is run on the bad config and any new config that
-# appears will be added to the configs to test.
+# It then reads the configs that are set, as well as the ones that are
+# not set for both the good and bad configs, and then compares them.
+# It will set half of the good configs within the bad config (note,
+# "set" means to make the bad config match the good config, a config
+# in the good config that is off, will be turned off in the bad
+# config. That is considered a "set").
#
-# Finally, it generates a config with the above result and runs it
-# again through make oldconfig to produce a config that should be
-# satisfied by kconfig.
+# It tests this new config and if it works, it becomes the new good
+# config, otherwise it becomes the new bad config. It continues this
+# process until there's only one config left and it will report that
+# config.
#
-# Then it starts the bisect.
+# The "bad config" can also be a config that is needed to boot but was
+# disabled because it depended on something that wasn't set.
#
-# The configs to test are cut in half. If all the configs in this
-# half depend on a config in the other half, then the other half
-# is tested instead. If no configs are enabled by either half, then
-# this means a circular dependency exists and the test fails.
+# During this process, it saves the current good and bad configs in
+# ${TMP_DIR}/good_config and ${TMP_DIR}/bad_config respectively.
+# If you stop the test, you can copy them to a new location to
+# reuse them again.
#
-# A config is created with the test half, and the bisect test is run.
-#
-# If the bisect succeeds, then all configs in the generated config
-# are removed from the configs to test and added to the configs that
-# will be enabled for all builds (they will be enabled, but not be part
-# of the configs to examine).
-#
-# If the bisect fails, then all test configs that were not enabled by
-# the config file are removed from the test. These configs will not
-# be enabled in future tests. Since current config failed, we consider
-# this to be a subset of the config that we started with.
-#
-# When we are down to one config, it is considered the bad config.
-#
-# Note, the config chosen may not be the true bad config. Due to
-# dependencies and selections of the kbuild system, mulitple
-# configs may be needed to cause a failure. If you disable the
