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

2023-09-20T16:10:50+00:00

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.

selftests: ALSA: remove unused variables

2023-09-11T06:20:52+00:00

These variables are never referenced in the code, just remove them.

kselftest/alsa: pcm - move more configuration to configuration files

2023-01-02T14:07:35+00:00

Obtain all test parameters from the configuration files. The defaults
are defined in the pcm-test.conf file. The test count and parameters
may be variable per specific hardware.

Also, handle alt_formats field now (with the fixes in the format loop).
It replaces the original "automatic" logic which is not so universal.

The code may be further extended to skip various tests based
on the configuration hints, if the exact PCM hardware parameters
are not available for the given hardware.

selftests: alsa - move shared library configuration code to conf.c

2022-11-29T14:05:18+00:00

The minimal alsa-lib configuration code is similar in both mixer
and pcm tests. Move this code to the shared conf.c source file.

Also, fix the build rules inspired by rseq tests. Build libatest.so
which is linked to the both test utilities dynamically.

Also, set the TEST_FILES variable for lib.mk.

selftests: alsa - add PCM test

2022-11-16T14:02:17+00:00

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.

v1..v2:
  - added missing alsa-local.h header file
