Dear all, My work for ALSA firewire stack was pulled into Linux 3.16, therefore Linux 3.16 newly supports 60-70 firewire sound devices. The work may affects user-space applications such like FFADO. Additionally, I leave some issues for the stack. So I wrote a report about my work. PDF: https://github.com/takaswie/alsa-firewire-report/blob/master/firewire.pdf Repository: https://github.com/takaswie/alsa-firewire-report Table of contents 1. Introduction 2. Common Specifications 3. Device features 4. Existing drivers 5. Investigation for user-land driver 6. Investigation for kernel-land driver 7. Enhancement of ALSA firewire stack 8. Driver implementation 9. Rest of issue I hope ALSA maintainers to read section 8 and 9. For FFADO developers, section 3, 5, 8 will be good information. For JACK/PulseAudio and Linux firewire subsystem developers, section 4, 5, 6, 7, 9 will be good information. I'm not a good English writer and have a little experiences to write technical documents. It's my glad to receive some corrections, indications, supplements and so on from you. Regards Takashi Sakamoto o-takashi at sakamocchi.jp
