The IPC allows transmission of requests, handling of responses as well as unsolicited (i.e. firmware-generated) notifications. A subscription mechanism is added to enable different parts of the driver to register for specific notifications. The boot process involving ROM-code requires specific handling with 'unstall' operations which are not required post-boot with normal IPC so separate set of send-message handlers is added for each of the usecases.

Their lifecycle, similarly to pipelines is being controlled by IPCs: initialization, deletion and (un)binding. Modules can be configured at runtime - runtime parameters. This is done with help of LARGE_CONFIG IPCs: getter and setter.

Once transferred, given stream is returned to pool available for audio streaming. Module loading handler is dummy as library and module code became inseparable in later firmware generations.
