ASoC: SOF: Intel: clarify Copyright information

For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.

ASoC: SOF: Remove the get_stream_position callback

The get_stream_position has been replaced by get_dai_frame_counter and all related code can be dropped form the core.

ASoC: SOF: Introduce a new callback pair to be used for PCM delay reporting

2024-03-25T16:35:56+00:00

For delay calculation we need two information: Number of bytes transferred between the DSP and host memory (ALSA buffer) Number of frames transferred between the DSP and external device (link/codec/DMIC/etc). The reason for the different units (bytes vs frames) on host and dai side is that the format on the dai side is decided by the firmware and might not be the same as on the host side, thus the expectation is that the counter reflects the number of frames. The kernel know the host side format and in there we have access to the DMA position which is in bytes. In a simplified way, the DSP caused delay is the difference between the two counters. The existing get_stream_position callback is defined to retrieve the frame counter on the DAI side but it's name is too generic to be intuitive and makes it hard to define a callback for the host side. This patch introduces a new set of callbacks to replace the get_stream_position and define the host side equivalent: get_dai_frame_counter get_host_byte_counter Subsequent patches will remove the old callback.

ASoC: SOF: Extend ChainDMA and DSPless mode to LNL+

2024-02-14T11:41:32+00:00

Merge series from Peter Ujfalusi : For both ChainDMA and DSPless mode the requirement is that the link must be serviced by HD-DMA. On pre Lunar Lake platforms this was only valid for HDAudio links but with Lunar Lake all link types now serviced by HD-DMA. This allows us to enable ChainDMA and DSPless mode for SoundWire links as well.

ASoC: SOF: Fix runtime pm usage counter balance after fw exception

2024-02-13T14:22:57+00:00

If the retain context is enabled we will unconditionally increment the device's pm use count on each exception and when the drivers are unloaded we do not correct this (as we don't know how many times we 'prevented d3 entry'). Introduce a flag to make sure that we do not increment the use count more than once and on module unload decrement the use count if needed to balance it.

Reuse existing function to get the interface mask and expose it to the SOF core with a callback - the main user is the IPC4 topology so only HDaudio platforms provide this callback.

ASoC: SOF: ops: add new 'is_chain_dma_supported' callback

2024-02-13T13:28:52+00:00

IPC4 introduced a 'chain-dma' mode when host and link DMA are connected by firmware without using a regular pipeline or the ability to add intermediate connections. This mode is not available on all platforms and all links, so add a platform-specific callback to help the SOF ipc4-topology core handle different hardware+firmware configurations.
