[PATCH] kselftest/alsa: Use card name rather than number in test names
From: Mark Brown
Date: Thu Jul 11 2024 - 10:34:51 EST
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 long name since in the
case where we have two of the same card it is more likely to include
deduplication information (eg, HDA cards include the address/IRQ). The
resulting information is not the most beautiful for human readers but the
majority of kselftest output consumption is automated systems and it wasn't
that great anyway.
