# 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.)
5
#
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.
12
#
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.
15
#
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.
19
#
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.
22
#
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).
27
#
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.
37
#
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.
