From 7b3b0d8583c926547fed8e493344cd8b30aa847d Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Fri, 25 Apr 2014 22:44:49 +0900 Subject: [PATCH] ALSA: firewire-lib: Add support for duplex streams synchronization in blocking mode Generally, the devices can synchronize to handle 'presentation timestamp' in CIP packets. This commit adds functionality to pick up this timestamp from in-packets transmitted by the device, then use it for out packets. In current implementation, this module generated the timestamp by itself. This is 'SYT Match' mode. Then drivers with this module acts as synchronization master. This commit allows this module to act as synchronization slave. This commit restricts this mechanism is only available in blocking mode because handling the timestamp in non-blocking mode is more complicated than in blocking mode.
