Some are part of loadable libraries. These need to be loaded after base firmware reports ready status through FW_READY notification. Their loading process is similar to the base firmware's one. Request the binary file, verify and strip the manifest and load the actual code into DSP memory with help of CLDMA or HD-Audio render stream, depending on audio device generation. List of libraries needed for loading is obtained through the topology - vendor sections specifying the name of firmware files to request.

With that in mind, implement all DAI operations to handle non-HDA BE interfaces. To prevent code duplication in newly added code, I2S platform registering is dynamic - makes use of specified port_mask and TDMs array to populate as many DAIs as required.

Another difference when compared to its DMIC and I2S friends is lack of NHLT blob usage - no additional hardware configuration is needed. Similarly to I2S component, HDA populates its DAIs dynamically, here by the means of codec->pcm_list_head. Allows for cutting the number of soc components required to support the interface.

While coredump is one of these, traces are the main area of interest. kfifo is enlisted to cache log data that is being pumped to driver through SRAM. Separate DSP operations are declared as actual feature implementation differs between firmware generations. As log gathering involves usage of IPCs, add all necessary: ENABLE_LOGS and SYSTEM_TIME.

When entered, certain domains which are not being currently used become power gated. Entering and leaving D0ix is a complex process and differs between firmware generations. Conditions that disallow D0i3 and require immediate D0i0 transition include but may not be limited to: IPC traffic, firmware tracing and SRAM I/O. To make D0ix toggling sane, delay D0i3 transition and refresh the timer each time an IPC is requested.

Super-card approach (e.g.: I2S, DMIC and HDA DAIs combined) is deprecated in favour of individual cards - one per each device. This provides necessary dynamism, especially for configurations with number of codecs present and makes it easier to survive auxiliary devices failures - one card failing to probe does not prevent others from succeeding. All boards spawned by AVS are unregistered on ->remove(). This includes dummy codecs such as DMIC. As all machine boards found in sound/soc/intel/boards are irreversibly tied to 'super-card' approach, new boards are going to be introduced. This temporarily increases number of boards available under /intel directory until skylake-driver becomes deprecated and removed.

These differ from SKL-alike ones in terms of AudioDSP firmware generation and thus the '+' suffix. Introduciton of IMR, removal of CLDMA, D0IX support and monolithic-ation of library/module code are most impactful but are not the only changes brought with this newer generation. Some generic and 1.5 operations are being re-used to reduce code size.
