Routing Audio to DSP vs. aloop) - - Routing audio to hardware to reduce overhead - 3. Inability to secure on all audio streams - - Substreams cannot have SMACK labels applied, inherently leaving different audio streams insecure, or a single label applied to all. +1.

AVIRT attempts to address the aforementioned problems by: - 1. Providing a standard interface through configfs to configure a variable number of 'streams' which can be mapped to audio paths. - 2. Optimize the audio routing by connecting directly with the desired audio path. This can include routing audio through directly to hardware, or to an implemented loopback interface. - 3.

Each 'stream' is separated to its own device, therefore security can be applied to each 'stream'. This means that each of the audio roles can be separately secured from each other. A sample dummy Audio Path is provided as an example to show how a low-level audio driver would subscribe to AVIRT, and accept audio routing for playback. |
