2024-12-20selftests/alsa: Fix circular dependency involving global-timerLi Zhijian
The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular dependency on the global-timer target due to its inclusion in $(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency warning during the build process. To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change ensures that libatest.so is built before any other targets that require it, without creating a circular dependency. This fix addresses the following warning: make[4]: Entering directory 'tools/testing/selftests/alsa' make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped. make[4]: Nothing to be done for 'all'. make[4]: Leaving directory 'tools/testing/selftests/alsa' Cc: Mark Brown <broonie@kernel.org> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Link: https://patch.msgid.link/20241218025931.914164-1-lizhijian@fujitsu.com Signed-off-by: Takashi Iwai <tiwai@suse.de>

2024-09-30selftest: alsa: check if user has alsa installedAbdul Rahim
Currently, if alsa development package is not installed on the user's system then the make command would print a `pagefull` of errors. In particular one error message is repeated 3 times. This error is returned by `pkg-config` and since it is not being handeled appropriately, repeated calls to `pkg-config` prints the same message again. This patch adds check for alsa package installation. If alsa is not installed, a short and consize error is returned. Also, it does not affect the compilation of other tests.

2024-08-18selftests: ALSA: Cover userspace-driven timers with testIvan Orlov
Add a test for the new functionality of userspace-driven timers and the tool which allows us to count timer ticks in a certain time period. The test: 1. Creates a userspace-driven timer with ioctl to /dev/snd/timer 2. Starts the `global-timer` application to count the ticks of the timer from step 1. 3. Asynchronously triggers the timer multiple times with some interval 4. Compares the amount of caught ticks with the amount of trigger calls. Since we can't include <alsa/asoundlib.h> and <sound/asound.h> in one file due to overlapping declarations, I have to split the test into two applications: one of them counts the amount of timer ticks in the defined time period, and another one is the actual test which creates the timer, triggers it periodically and starts the first app to count the amount of ticks in a separate thread. Besides from testing the functionality itself, the test represents a sample application showing userspace-driven ALSA timers API. Also, the timer test includes a test case which tries to create a timer with invalid resolution (=0), and NULL as a timer info structure.

2024-07-18kselftest/alsa: Use card name rather than number in test namesMark Brown
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.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for for v6.11 There are a lot of changes in here, though the big bulk of things is cleanups and simplifications of various kinds which are internally rather than externally visible. A good chunk of those are DT schema conversions, but there's also a lot of changes in the code. Highlights: - Syncing of features between simple-audio-card and the two audio-graph cards so there is no reason to stick with an older driver. - Support for specifying the order of operations for components within cards to allow quirking for unusual systems. - New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5 and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242.

When validating writes to controls we check that whatever value we wrote actually appears in the control. For volatile controls we cannot assume that this will be the case, the value may be changed at any time including between our write and read.

2024-03-05selftests: avoid using SKIP(exit()) in harness fixure setupJakub Kicinski
selftest harness uses various exit codes to signal test results. Avoid calling exit() directly, otherwise tests may get broken by harness refactoring (like the commit under Fixes). SKIP() will instruct the harness that the test shouldn't run, it used to not be the case, but that has been fixed. So just return, no need to exit. Note that for hmm-tests this actually changes the result from pass to skip. Which seems fair, the test is skipped, after all.

We've got a bunch of new drivers in here, a bit of core work from Morimoto-san and quite a lot of janitorial work. There's several updates that pull in changes from other subsystems in order to build on them: - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in some IIO changes. - Create a library function for intlog10() and use it in the NAU8825 driver. - Include the ASoC tests, including the topology tests, in the default KUnit full test coverage. This also involves enabling UML builds of ALSA since that's the default KUnit test environment which pulls in the addition of some stubs to the driver. - More factoring out from Morimoto-san. - Convert a lot of drivers to use the more modern maple tree register cache. - Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.

2023-06-07selftests: ALSA: Add test for the 'pcmtest' driverIvan Orlov
This test covers the new Virtual PCM Test Driver, including the capturing, playback and ioctl redefinition functionalities for both interleaved and non-interleaved access modes. This test is also helpful as an usage example of the 'pcmtest' driver. We have a lot of different virtual media drivers, which can be used for testing of the userspace applications and media subsystem middle layer. However, all of them are aimed at testing the video functionality and simulating the video devices. For audio devices we have only snd-dummy module, which is good in simulating the correct behavior of an ALSA device. I decided to write a tool, which would help to test the userspace ALSA programs (and the PCM middle layer as well) under unusual circumstances to figure out how they would behave. So I came up with this Virtual PCM Test Driver. This new Virtual PCM Test Driver has several features which can be useful during the userspace ALSA applications testing/fuzzing, or testing/fuzzing of the PCM middle layer. Not all of them can be implemented using the existing virtual drivers (like dummy or loopback). Here is what can this driver do: - Simulate both capture and playback processes - Generate random or pattern-based capture data - Check the playback stream for containing the looped pattern - Inject delays into the playback and capturing processes - Inject errors during the PCM callbacks Also, this driver can check the playback stream for containing the predefined pattern, which is used in the corresponding selftest to check the PCM middle layer data transferring functionality. Additionally, this driver redefines the default RESET ioctl, and the selftest covers this PCM API functionality as well. The driver supports both interleaved and non-interleaved access modes, and have separate pattern buffers for each channel. The driver supports up to 4 channels and up to 8 substreams.

People looking at test logs may not have direct access to the target system. This will increase the amount we write to the console, hopefully that's buffered.

2023-03-08kselftest/alsa - mixer-test: Don't fail tests if we can't restore defaultMark Brown
If a control has an invalid default value then we might fail to set it when restoring the default value after our write tests, for example due to correctly implemented range checks in put() operations. Currently this causes us to report the tests we were running as failed even when the operation we were trying to test is successful, making it look like there are problems where none really exist. Stop doing this, only reporting any issues during the actual test. We already have validation for the initial readback being in spec and for writing the default value back so failed tests will be reported for these controls, and we log an error on the operation that failed when we write so there will be a diagnostic warning the user that there is a problem.

2023-02-04kselftest/alsa: Run PCM tests for multiple cards in parallelMark Brown
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.

2023-01-02kselftest/alsa: pcm - Add more coverage by defaultMark Brown
Add more coverage to our standard test cases: - 8kHz mono and stereo to verify that the most common mono format is clocked correctly. - 44.1kHz stereo to verify that this different clock base is generated accurately. - 48kHz 6 channel to verify that 6 channel is clocked correctly. - 96kHz stereo since that is a common audiophile rate.

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.

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.

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.
