-/**
- * Represents the ADSP embedded within the audio sysmodule.
- * This is a 32-bit Linux4Tegra kernel from nVidia, which is launched with the sysmodule on boot.
- *
- * The kernel will run apps you program for it, Nintendo have the following:
- *
- * Gmix - Responsible for mixing final audio and sending it out to hardware. This is last place all
- *        audio samples end up, and we skip it entirely, since we have very different backends and
- *        mixing is implicitly handled by the OS (but also due to lack of research/simplicity).
- *
- * AudioRenderer - Receives command lists generated by the audio render
- *                 system, processes them, and sends the samples to Gmix.
- *
- * OpusDecoder - Contains libopus, and controls processing Opus audio and sends it to Gmix.
- *               Not much research done here, TODO if needed.
- *
- * We only implement the AudioRenderer for now.
- *
- * Communication for the apps is done through mailboxes, and some shared memory.
