Currently for the PCM and mixer tests we report test names which identify
the card being tested with the card number. This ensures we have unique
names but since card numbers are dynamically assigned at runtime the names
we end up with will often not be stable on systems with multiple cards
especially where those cards are provided by separate modules loeaded at
runtime. This makes it difficult for automated systems and UIs to relate
test results between runs on affected platforms.
Address this by replacing our use of card numbers with card names which are
more likely to be stable across runs. We use the card ID since it is
guaranteed to be unique by default, unlike the long name. There is still
some vulnerability to ordering issues if multiple cards with the same base
ID are present in the system but have separate dependencies but not all
drivers put distinguishing information in their long names.

When parsing the configs, keep track of card configurations that match
the current system but haven't matched any card, and report those as
test failures as they represent that a card which was expected to be
present on the system is missing. This allows the configuration files to
not only be used to detect missing PCM devices (which is currently
possible) but also that the soundcard hasn't been registered at all.

Currently test_pcm_time() streams audio on each PCM with each
configuration for 4 seconds. This time can add up, and with the current
45 second kselftest timeout, some machines like mt8192-asurada-spherion
can't even run to completion. Lower the duration to 2 seconds to cut the
test duration in half, without reducing the test coverage.

When reporting errors or skips we currently include the diagnostic message
indicating why we're failing or skipping. This isn't ideal since KTAP
defines the entire print as the test name, so if there's an error then test
systems won't detect the test as being the same one as a passing test. Move
the diagnostic to a separate ksft_print_msg() to avoid this issue, the test
name part will always be the same for passes, fails and skips and the
diagnostic information is still displayed.

With each test taking 4 seconds the runtime of pcm-test can add up. Since
generally each card in the system is physically independent and will be
unaffected by what's going on with other cards we can mitigate this by
testing each card in parallel. Make a list of cards as we enumerate the
system and then start a thread for each, then join the threads to ensure
they have all finished. The threads each run the same tests we currently
run for each PCM on the card before exiting.
The list of PCMs is kept global since it helps with global operations
like working out our planned number of tests and identifying missing PCMs
and it seemed neater to check for PCMs on the right card in the card
thread than make every PCM loop iterate over cards as well.
We don't run per-PCM tests in parallel since in embedded systems it can
be the case that resources are shared between the PCMs and operations on
one PCM on a card may constrain what can be done on another PCM on the same
card leading to potentially unstable results.
We use a mutex to ensure that the reporting of results is serialised and we
don't have issues with anything like the current test number, we could do
this in the kselftest framework but it seems like this might cause problems
for other tests that are doing lower level testing and building in
constrained environments such as nolibc so this seems more sensible.
Note that the ordering of the tests can't be guaranteed as things stand,
this does not seem like a major problem since the numbering of tests often
changes as test programs are changed so results parsers are expected to
rely on the test name rather than the test numbers. We also now prefix the
machine generated test name when printing the description of the test since
this is logged before streaming starts.
On my two card desktop system this reduces the overall runtime by a
third.

the output of the program in logs let's provide support for an optional
'description' directive which we log prior to running each of the tests.

Since we don't know what the capabilities of an unknown card is any of our
standard tests may fail due to not being supported by the system. Set a
flag once we've configured the stream, just before we start data, to say
that the system accepted our stream configuration.
Since there shouldn't be a use case for tests that are specified for the
individual system failing for those tests we also add a new test which
fails if we are unable to configure the settings specified in the system
specific configuration file.

Rather than allowing the system specific tests to replace the default set
of tests instead run them in addition to the standard set of tests. In
order to avoid name collisions in the reported tests we add an additional
test class element to the reported tests. Doing this means we always get a
consistent baseline of coverage no matter what card we run on but retain
the ability to specify specific coverage for a given system.

Now that we can skip unsupported configurations add some more test cases
using that, cover 8kHz, 44.1kHz and 96kHz plus 8kHz mono and 48kHz 6
channel.
44.1kHz is a different clock base to the existing 48kHz tests and may
therefore show problems with the clock configuration if only 8kHz based
rates are really available (or help diagnose if bad clocking is due to
only 44.1kHz based rates being supported). 8kHz mono and 48Hz 6 channel
are real world formats and should show if clocking does not account for
channel count properly.

This initial code does a simple sample transfer tests. By default,
all PCM devices are detected and tested with short and long
buffering parameters for 4 seconds. If the sample transfer timing
is not in a +-100ms boundary, the test fails. Only the interleaved
buffering scheme is supported in this version.
The configuration may be modified with the configuration files.
A specific hardware configuration is detected and activated
using the sysfs regex matching. This allows to use the DMI string
(/sys/class/dmi/id/* tree) or any other system parameters
exposed in sysfs for the matching for the CI automation.
The configuration file may also specify the PCM device list to detect
the missing PCM devices.
