Hi Mark, Many thanks for this. At first sight, that sounds good ! Do you want a deeper code review, and if yes, through what channel ? Do you have a rough estimated roadmap ? Cheers Thierry On 08/27/2018 08:08 AM, Mark Farrugia wrote:
Hi all, We have published our initial version of the Virtual Sound Driver that we at Fiberdyne Systems have been working on recently. The source can be found for your perusal here: https://github.com/fiberdyne/avirt The driver currently consists of: - A top-level ALSA driver, avirt_core - A low-level dummy example "Audio Path", dummyap The top-level ALSA driver implements a dynamically configurable abstract ALSA middle-layer interface, and would be the global point of entry for audio streams in AGL. The low-level driver then subscribes as an "Audio Path", resulting in switchable kernel-space routing from the top-level driver to the low-level driver. The top-level driver also: - Builds streams as individual devices, allowing for separate SMACK security labels per sound stream (i.e. A "radio" stream can now have a different security context to an "emergency" stream) - Builds PCM devices with configurable names and channels, which can be defined by 4A HALs, or externally. We are open to suggestions and feedback.
