// C ABI over the Tactility app-framework's audio service (output volume/mute, play-pause
|
|
// latch), exported to side-loaded ELF apps through the "tactility-audio" kernel module's symbol
|
|
// table (see Tactility/Source/service/audio/AudioExports.cpp in the firmware repo, which
|
|
// implements these against tt::service::audio::*). ABI-stable: an app compiles against these
|
|
// declarations and the ELF loader resolves the calls against the running firmware's exports.
|
|
//
|
|
// This is service-layer, not a kernel driver - it doesn't touch a Device directly, it reflects
|
|
// the app-facing audio service's state (the active output codec, whichever one that is).
