# BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e

+# For TEST_TYPE = config_bisect
+#
+# In those cases that you have two different configs. One of them
+# work, the other does not, and you do not know what config causes
+# the problem.
+# The TEST_TYPE config_bisect will bisect the bad config looking for
+# what config causes the failure.
+#
+# 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.
+#
+# 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).
+#
+# An oldconfig is run on the bad config and any new config that
+# appears will be added to the configs to test.
+#
+# 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.
+#
+# Then it starts the bisect.
+#
+# 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.
+#
+# 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
+# config that was found and restart the test, if the test fails
+# again, it is recommended to rerun the config_bisect with a new
+# bad config without the found config enabled.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# CONFIG_BISECT_TYPE is the type of test to perform:
+# build - bad fails to build
+# boot - bad builds but fails to boot
+# test - bad boots but fails a test
+#
+# CONFIG_BISECT is the config that failed to boot
