[alsa-devel] Semantics of a single period per buffer?

[Dave Dillow]

While refining the sis7019 for submission, I found a possible issue with
having a single period per buffer. The easy way out is to set the
minimum number of periods to 2, but I see other drivers allow a single
period. This leads to a question about the semantics of a single period
that I've not been able to resolve using Google.

Any one have any thoughts or pointers to a discussion on having a single
period per buffer? Should it be a one-shot play, or just let it hit XRUN
every time? Other ideas?

Thanks,
Dave
