This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards.

base-commit: 1d8025ec722d5e011f9299c46274eb21fb54a428
In order to help make the list of tests a bit easier to maintain refactor things so we pass the tests around as a struct with the parameters in, enabling us to add new tests by adding to a table with comments saying what each of the number are. We could also use named initializers if we get more parameters.

The values in the one example configuration file we currently have are the default values for the two tests we have so there's no need to actually set them. Comment them out as examples, with a rename for the tests so that we can update the tests in the code more easily.

Rather than just numbering the tests try to provide semi descriptive names for what the tests are trying to cover. This also has the advantage of meaning we can add more tests without having to keep the list of tests ordered by existing number which should make it easier to understand what we're testing and why.

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.

It looks like the period/buffer size numbers need some tuning other than for 44.1kHz and 48kHz 6 channel, if I do any more fiddling with this series I'll split the problematic ones out into a separate commit if I don't get things sorted (but we could just leave things as-is and fix incrementally too I guess).

The current code allows to override "test.time1 {} test.time2 {}" blocks in the configuration files which is equivalent to "test { time1 {} time2 {} }". This changeset will introduce configuration lookups like "pcm.0.0.PLAYBACK.44k1.2.big {}" which creates another configuration structure. The '.' (compound level delimiter) should not be used in the test name.
My original idea for the next improvement was to parse the "pcm.0.0.PLAYBACK.test" compound and gather the tests for the given pcm. If this compound is missing, we can continue with the hard-coded defaults.
About the skips - the test should probably keep to support also the exact parameters. For example - if the hardware must support 6 channels, it should not be a skip but an error. Everything may be broken, including the PCM configuration refining.
I just sent the patch with my changes for comments [1]. It's just the base code which may be extended with your requirements. The skips may be implemented using configuration field like 'skip_if_rate_error yes' or so. Let me know, if I can stack your changes on top, or perhaps, you may be willing to adapt them.

Right, I was leaving that in place but just renaming so that the intent of the test was clearer and expanding the standard coverage - trying to make it clearer what the test was trying to accomplish when someone comes along trying to do something later on. It did however cross my mind that we might be better off having the tests read from the config file be in addition to the standard tests rather than overriding them, I think that'd work out a lot clearer in the end.

I see, we could use another delimiter there easily enough (though if we segregated the built in and loaded test configurations I'm not sure it'd matter so much).
My original idea for the next improvement was to parse the "pcm.0.0.PLAYBACK.test" compound and gather the tests for the given pcm. If this compound is missing, we can continue with the hard-coded defaults.
While it is useful to be able to specify additional tests through configuration I don't think we should be relying on that for coverage, we should have a more substantial baseline of tests so that systems like KernelCI get reasonable coverage without having to get changes individually integrated for boards (and then wait for them to filter out into the trees being tested). It doesn't scale out so well over the number of systems that we might be running on, especially if we come up with new tests and have to loop back over existing boards, and isn't really idiomatic for kselftest.
I'm also a bit worried about the way we currently override the built in tests, it creates additional potential for confusion when looking at results if the test might've been turned into something different by the configuration file.
About the skips - the test should probably keep to support also the exact parameters. For example - if the hardware must support 6 channels, it should not be a skip but an error. Everything may be broken, including the PCM configuration refining.
Yes, there's a tension there between hard coded tests and the explicitly specified per board ones. I think the solution here is to add two tests for things we read from the configuration file rather than just adding by default, one verifying that we managed to configure the settings we asked for and one for the actual test.
I just sent the patch with my changes for comments [1]. It's just the base code which may be extended with your requirements. The skips may be implemented using configuration field like 'skip_if_rate_error yes' or so. Let me know, if I can stack your changes on top, or perhaps, you may be willing to adapt them.

Ah then it was my misunderstanding, and everything should be fine now ;) Thanks!
Erm, you meant sent as *v3*. I've seen now.
As the v2 patches were already merged, could you rather rebase and resubmit? I'd like to avoid rebase the full series that are already included in linux-next.
Apologies for the mess.

Let me know, if I can stack your changes on top, or perhaps, you may be willing to adapt them.
As Mark has already sent a v2 series, I applied his v2 at first. Could you rebase and resubmit on top of my for-next branch?
Oh, this is getting a little confusing - I'd just picked Jaroslav's patch into my tree and was in the middle redoing my ideas on top of his code! I might have something more later this evening... I think we can converge here, let me continue taking a look.

It's rebased. The first patch from the set drops the previous Mark's changes.

Indeed, there was so many collisions with Jaroslav's patches which it just seemed like the most straightforward way to do things (plus I'd already written a good chunk of the new version by the time you applied my v2). Probably only a small bit of the skipping code would end up remaining anyway.
