NAME

6       snd_pcm_trigger_done - Mark the master substream
7

SYNOPSIS

9       void snd_pcm_trigger_done(struct snd_pcm_substream * substream,
10                                 struct snd_pcm_substream * master);
11

ARGUMENTS

13       substream
14           the pcm substream instance
15
16       master
17           the linked master substream
18

DESCRIPTION

20       When multiple substreams of the same card are linked and the hardware
21       supports the single-shot operation, the driver calls this in the loop
22       in snd_pcm_group_for_each_entry for marking the substream as “done”.
23       Then most of trigger operations are performed only to the given master
24       substream.
25
26       The trigger_master mark is cleared at timestamp updates at the end of
27       trigger operations.
