This 14 patchset is to enable ALSA Dice driver to handle more models with some functionalities:
- up to 192.0 kHz
- PCM capture
- MIDI playback/capture
- Duplex streams with synchronization (with snd-firewire-lib)
This driver doesn't support:
- Synchronization between multiple devices on the same bus For this purpose, please join in user-space driver project (FFADO)
- Any control functionality for internal DSP For this purpose, please use ffado-dbus-server/ffado-mixer, or write your own application
Remarks:
- When this driver is loaded, user-space driver fails to register notification address, thus cannot handle device for streaming. See:

Updates from my previous RFC: http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081673.h...
- Improve bus reset handling, especially for registering notification address At bus reset, Dice devices initialize a register for notification address, then drivers need to register the address again. Just after powering on, devices generates any bus reset, then drivers often fail to detect stream formation because this operation requires to change sampling rate. My improvement is retries to register notification address when notification wait is timed out.
- Remove experimental state
- Fix minor bugs
JFYI,
as the patches are massive and a bit intrusive, they won't fit with 3.18 merge, unfortunately. So we'll plenty of time for review :)
thanks,
