Subject: [PATCH 00/10] ALSA: firewire-lib: pool sequence of syt offset and data blocks in AMDTP domain structure
Date: Fri, 8 May 2020 13:36:25 +0900 [thread overview]
Message-ID: <20200508043635.349339-1-o-takashi@sakamocchi.jp> (raw)
Hi,
In current implementation, the packets for outgoing AMDTP streams are
processed by per-stream calculation of syt offset and the number of data
blocks per packet.
This patchset is a preparation for future extension that the packets for
outgoing AMDTP streams are processed according to the result of 'sampling
clock recovery' in IEC 61883-6:2005 from selected incoming AMDTP stream.
The preparation is to process packets for outgoing AMDTP streams by pool
in AMDTP domain structure for the sequence of syt offset and the number
of data blocks. The way to generate sequence is still the same as the
current implementation, which generates by ideal sampling transmission
frequency against IEEE 1394 bus clock.
