In order to decide if ktest should bother installing modules on the
target box, it checks if the config file has CONFIG_MODULES=y. But it
also checks if the '=y' part exists. It only will install modules if the
config exists and is set with '=y'. But as the regex that was used
tests:
/^CONFIG_MODULES(=y)?/
this will also match:
CONFIG_MODULES_USE_ELF_RELA
as the '=y' part was optional and it did not test the rest of the line.
When this happens, ktest will stop checking the rest of the configs but
it will also think that no modules are needed to be installed. What it
should do is only jump out of the loop if it actually found a
CONFIG_MODULES that is set to true.
Otherwise, ktest wont install the necessary modules needed for proper
booting of the test target.

As 67d34a6a39 said, 'oldnoconfig' doesn't
set new symbols to 'n', but instead sets it to their default values.
So, this patch replaces 'oldnoconfig' with 'olddefconfig', stop making
people confused, and keep the old name 'oldnoconfig' as an alias,
because people already are dependent on its behavior with the
counter-intuitive name.

The ELSE IF statements do not work as expected if another ELSE statement
follows. This is because the $if_set is not set. If the ELSE IF
condition is true, the following ELSE should be ignored. But because the
$if_set is not set, the following ELSE will also be executed.

The option IGNORE_ERRORS is used to allow a test to succeed even if a
warning appears from the kernel. Sometimes kernels will produce warnings
that are not associated with a test, and the user wants to test
something else.
The IGNORE_ERRORS works for boot up, but was not preventing test runs to
succeed if the kernel produced a warning.

The min configs are saved in a perl hash called force_configs, and this
hash is used to add configs to the .config file. But it was not being
reset between tests and a min config from a previous test would affect
the min config of the next test causing undesirable results.
Reset the force_config hash at the start of each test.

Usually the target is booted into a dependable kernel when a test
starts. The test will install the test kernel and reboot the box. But
there may be a time that the kernel is running an unreliable kernel and
the reboot may crash.
Have ktest detect crashes on a reboot and force a power-cycle instead.
This can usually happen if a test kernel was installed to run manual
tests, but the user forgot to reboot to the known good kernel.

If the console is constantly outputting content, this can cause ktest
to get stuck waiting on the monitor to settle down.
The option MAX_MONITOR_WAIT is the maximum time (in seconds) for ktest
to wait for the console to flush.

With a name like 'oldnoconfig' one may think that the config generated
would disable all configs that were not defined (selecting "no" for all
options). But this is not the case. It selects the default. If a config
has a 'default y', then it is added if not specified.
This broke the config bisect, because options not specified by a config
will just use the default, where it expected to turn off. This caused an
option to be enabled that disabled an option that would break the build.
The end result was that we never found the bad config at the end of the
test.
Instead of using 'make oldnoconfig', ktest now builds the options it
expects enabled and disabled. When it turns off an option, it will no
longer remove it, but actually set it to:
# CONFIG_FOO is not set.

The config-bisect can take a bad config and bisect it down to find out
what config actually breaks the config. But as all tests will apply a
minconfig (defined by a user) to apply before booting, it is possible
that the minconfig could actually make the bad config work (minconfigs
can disable configs). The end result is that the config bisect test will
not find a config that breaks. This can be rather frustrating to the
user.
The CONFIG_BISECT_CHECK option, when set to 1, will make sure that the
bad config (with the minconfig applied) still fails before trying to
bisect.
And yes, I did get burned by this.

In order to let the user add commands before and after ktest runs, the
PRE_KTEST and POST_KTEST options are defined. They hold shell commands
that will execute befor ktest runs its first test, as well as when it
completed its last test.
The PRE_TEST and POST_TEST will be run befor and after (respectively)
for a given test. They can either be global (done for all tests) or
defined by a single test.

Add the config that I use to test several archs. I downloaded several
cross compilers from:
http://kernel.org/pub/tools/crosstool/files/bin/x86_64/
and this config is an example to crosscompile several archs to make sure
that your changes do not break archs that you are not working on.

I've been asked several times to provide more useful example configs for
ktest.pl, as the sample.conf is too complex (because it explains all
configs). This adds configs broken up by use case, and these configs are
based on actual configs that I use on a daily basis.

If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the
user and ask them if the OUTPUT_MIN_CONFIG should be used as the
starting point for make_min_config instead of MIN_CONFIG.
This is usually the case, and to allow the user to do so, which is
helpful if the user is creating different min configs based on tests,
and they know one is a superset of another test, they can set
USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting
to use the OUTPUT_MIN_CONFIG and it will just use it.
If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to
use MIN_CONFIG instead.
The default is that USE_OUTPUT_MIN_CONFIG is undefined.

Add a MIN_CONFIG_TYPE that can be set to 'test' or 'boot'. The default
is 'boot' which is what make_min_config has done previously: makes a
config file that is the minimum needed to boot the target.
But when MIN_CONFIG_TYPE is set to 'test', not only must the target
boot, but it must also successfully run the TEST. This allows the
creation of a config file that is the minimum to boot and also
perform ssh to the target, or anything else a developer wants.
