From b164d2fd6e4985e9270755477dde063e6e48461e Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Sun, 9 Apr 2017 21:33:27 +0900 Subject: ALSA: firewire_lib: add tracepoints for packets without CIP headers Unique protocol is used for RME Fireface series. In this protocol, payload format for isochronous packet is not compliant to CIP in IEC 61883-1/6. The packet includes data blocks just with data channels, without headers and any metadata. In previous commits, ALSA IEC 61883-1/6 engine supports this protocol. However, tracepoints are not supported yet, unlike implementation for IEC 61883-1/6 protocol. This commit adds support of tracepoints for the protocol.
