Subject: [PATCH 21/39] fireworks: Add connection and stream management
Date: Fri, 28 Feb 2014 12:27:34 +0900
Message-ID: <1393558072-25926-22-git-send-email-o-takashi@sakamocchi.jp> (raw)
In-Reply-To: <1393558072-25926-1-git-send-email-o-takashi@sakamocchi.jp>

Fireworks manages connections by CMP and can transmit/receive AMDTP streams
with a few quirks. This commit adds functionality to start/stop the streams.

Major Fireworks products don't support 'SYT-Match' modes, except for
AudioFire12/8(till 2009 July) with firmware version 1.0. Already in previous
commit, this driver don't support such old firmwares. So this commit adds
support for non 'SYT-Match' modes.

I note that this driver has a short gap for MIDI streams when starting PCM
stream. When AMDTP streams are running only for MIDI data and PCM data is
going to be joined at different sampling rate, then AMDTP streams are
stopped once and started again after changing sampling rate.

Fireworks quirks:

1.Fireworks transmits packets with both TAG0 and TAG1
In IEC 61883-1, each common isochronous packet (CIP) has 'tag' field in its
packet header. The value is generally 0x01 ('CIP header is included' = TAG1).
But Fireworks in 'IEC 61883 compliant mode' transmits 'no data' packet with 0x00
('No CIP header is included' = TAG0) but actually the packet includes CIP
structure. To handle 'presentation timestamp' for duplex streams
synchronization, this packets must be handled.

2.Fireworks transmits 'no data' packet out of specification
Fireworks transmits 'no data' packet with 'NO-DATA' FDF and no dummy data. It
includes CIP headers only. In IEC 61883-6, 'no data' packet is generated by two
ways. One is empty CIP packet defined in IEC 61883-1. Another is
'special non-empty packet' defined in IEC 61883-6. Fireworks uses strange
combination of them.

3.Fireworks transmits packets with a bit disorder
A sequence of DBC field in packets transmitted by Fireworks includes a bit
disorder. See logs in the end of this commit.

4.Fireworks can handle MIDI messages in the first 8 data blocks of out-packet
Fireworks ignores MIDI messages in other data blocks.

5.AudioFirePre8 transmits packets with wrong data block size
One of Fireworks device, AudioFirePre8, always reports 8 data block size in
transmitted packets and increments the data block counter by 8. But this is not
actual value.

I confirm them with firmware version 4.8 or later with Windows. According to
a contact persion in Echo Audio, there is no difference between firmwares
installed by Windows/OS X.

Here, an example of a sequence of packets transmitted by Fireworks:
