kselftest: alsa: fixed a print formatting warning

2023-12-18T08:15:21Z

A statement used %d print formatter where %s should have been used. The same has been fixed in this commit.

kselftest/alsa: pcm-test: Report cards declared in config but missing

2023-09-20T16:10:50Z

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.

Merge tag 'asoc-v6.6-early' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

ASoC: Updates for v6.6 Here's an initial batch of updates for ASoC for this release cycle. 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.

kselftest/alsa: pcm-test: Decrease stream duration from 4 to 2 seconds

2023-07-10T06:58:27Z

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. Signed-off-by: Nícolas F. R. A.

selftests: ALSA: Add test for the 'pcmtest' driver

2023-06-07T11:09:03Z

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.
