This patch adds an xrun counter to snd_pcm_substream as an alternative to using logs from XRUN_DEBUG_BASIC. The counter provides a way to track the number of xrun occurences, accessible through the /proc interface.
The counter is enabled when CONFIG_SND_PCM_XRUN_DEBUG is set.
Example output:
$ cat /proc/asound/card0/pcm9p/sub0/status
owner_pid : 1425 trigger_time: 235.248957291 tstamp : 0.000000000 delay : 1912 avail : 480 avail_max : 1920
