2022-03-11ASoC: Intel: avs: Add module management requestsCezary Rojewski3-1/+320
Firmware modules implement processing algorithms. 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. Due to firmware limitations, LARGE_CONFIG_GET handler implementation does not support retrieving payload with size larger than IPC inbox window size.

2022-03-11ASoC: Intel: avs: Add pipeline management requestsCezary Rojewski2-0/+124
Pipeline represents a scheduling entity. Their existence as well as their state machine is controlled through CREATE_PIPELINE, DELETE_PIPELINE and SET_PIPELINE_STATE IPCs.

2022-03-11ASoC: Intel: avs: Add code loading requestsCezary Rojewski3-1/+88
Before firmware and its modules can be used, they have to be loaded. Code loading process is complex and is a combination of DMA and IPC operations. Here, IPC part is being added and accounts for CLDMA and HDA mechanisms both.

2022-03-11ASoC: Intel: avs: Inter process communicationCezary Rojewski5-1/+692
Implement the IPC between Intel audio firmware and kernel driver. 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 part of the DSP boot process that involves sending ROM message requires an extra step - must be followed by unstall operation of MAIN_CORE. All other types of messages do not require such specific handling, so separate set of functions is provided for sending these.

2022-03-11ASoC: Intel: Introduce AVS driverCezary Rojewski4-0/+205
Declare base structures and core DSP operations for the avs solution. The base structures describe PCI HDAudio bus device and platform-type differentiations. First set of operations added controls the lifecycle of any Audio DSP core: (un)powering, (un)resetting and (un)stalling.
