/**
* 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 the apps you write 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 on the host, processes them, and sends the samples to Gmix.
*
* OpusDecoder - Contains libopus, and decodes Opus audio packets into raw pcm data.
*
* Communication between the host and ADSP is done through mailboxes, and mapping of shared memory.
