    ALSA: x86: Allow single period PCM operation · 8d48c016
    Takashi Iwai authored
    This is an implementation of PCM streaming with only 1 period.
    Since the hardware requires the refresh of BDs after each BD
    processing finishes, we'd need at least two BDs.  The trick is that
    both BDs point to the same content: the address of the PCM buffer
    head, and the whole buffer size.  Then it loops over to the whole
    buffer again after it finished once.
