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 Jaroslav Kysela perex@perex.cz 2022-11-29T08:53:06+00:00 b310092e3eec6e7be36ed2436577f406a1e5e8de 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 Jaroslav Kysela perex@perex.cz 2022-11-08T11:59:14+00:00 aba51cd0949aee50a2b93f1b32ed3668cd613649 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.
