2024-02-20ASoC: Intel: avs: Abstract IPC handlingCezary Rojewski
Servicing IPCs on CNL platforms and onward differs from the existing one. To make room for these, enrich platform descriptor with fields representing crucial IPC registers and utilize them throughout the code. While cleaning up device descriptors, reduce the number of code lines by assigning 'min_fw_version' within a single line.

2022-10-21ASoC: Merge HDA/ext cleanupMark Brown

2022-10-20ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layerPierre-Louis Bossart
The SPIB and DRMS capabilities are orthogonal to the DSP enablement and can be used whether the stream is coupled or not. The existing code partitioning makes limited sense, the capabilities are parsed at the sound/hda level but helpers are located in sound/hda/ext. This patch moves all the SPIB/DRMS functionality to the sound/hda layer. This reduces the complexity of the sound/hda/ext layer which is now limited to handling the multi-link extensions and stream coupling/decoupling helpers. Note that this is an iso-functionality code move and rename, the HDaudio legacy driver would need additional changes to make use of these capabilities.

2022-05-17ASoC: Intel: avs: APL-based platforms supportCezary Rojewski
Define handlers specific to cAVS 1.5+ platforms, that is, APL and similar platforms. 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.

2022-05-17ASoC: Intel: avs: Account for libraries when booting basefwCezary Rojewski
Not all modules are part of base firmware. 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.

2022-03-11ASoC: Intel: avs: Code loading over HDACezary Rojewski
Compared to SKL and KBL, more recent cAVS platforms are meant to re-use one of HDAudio streams during boot procedure causing CLDMA to become obsolete. Once transferred, given stream is returned to pool available for audio streaming. Module loading handler is stub as library and module code became inseparable in later firmware generations.
