ASoC: SOF: pcm: Restrict DSP D0i3 during S0ix to IPC3

2024-04-09T13:03:34Z

Introduce a new field in struct sof_ipc_pcm_ops that can be used to restrict DSP D0i3 during S0ix suspend to IPC3. With IPC4, all streams must be stopped before S0ix suspend.

ASoC: SOF: sof-pcm: Add pointer callback to sof_ipc_pcm_ops

2024-03-25T16:36:03Z

The IPC specific pointer callback can be used when additional or custom handling is needed during the pointer calculation, like executing a delay calculation at the same time to minimize drift between the reported pointer and the calculated delay.

ASoC: SOF: Add dsp_max_burst_size_in_ms member to snd_sof_pcm_stream

2024-03-25T16:35:51Z

The dsp_max_burst_size_in_ms can be used to save the length of the maximum burst size in ms the host DMA will use. Platform code can place constraint using this to avoid user space requesting too small ALSA buffer which will result xruns.

ASoC: SOF: topology: Parse DAI type token for dspless mode

2024-02-13T13:29:00Z

Starting with LunarLake, the dspless mode can handle SoundWire/ALH, DMIC and SSPs, so we need to identify the dai type from topology.

Merge tag 'asoc-v6.8' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-01-08T07:18:02Z

ASoC: Updates for v6.8 This is a relatively quiet release, there's a lot of driver specific changes and the usual high level of activity in the SOF core but the one big core change was Mormioto-san's work to support more N:M CPU:CODEC mapping cases. Highlights include: - Enhanced support for N:M CPU:CODEC mappings in the core and in audio-graph-card2. - Support for falling back to older SOF IPC versions where firmware for new versions is not available. - Support for notification of control changes generated by SOF firmware with IPC4. - Device tree support for describing parts of the card which can be active over suspend (for very low power playback or wake word use cases). - ACPI parsing support for the ES83xx driver, reducing the number of quirks neede for x86 systems. - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm SM8250, SM8550, SM8650 and X1E80100. - Removal of Freescale MPC8610 support, the SoC is no longer supported by Linux.

ASoC: SOF: ipc4-topology: Add core_mask in struct snd_sof_pipeline

2023-11-24T14:15:06Z

With IPC4, a pipeline may contain multiple modules in the data processing domain and they can be scheduled to run on different cores. Add a new field in struct snd_sof_pipeline to keep track of all the cores that are associated with the modules in the pipeline. Set the pipeline core mask for IPC3 when initializing the pipeline widget IPC structure. For IPC4, set the core mark when initializing the pipeline widget and initializing processing modules in the data processing domain.

ASoC: sof: Improve sof_ipc3_bytes_ext_put function

2023-05-23T18:31:14Z

The function is improved in the way that if the firmware returns a validation error on the newly sent bytes, then the kernel will automatically restore to the old bytes value for a given kcontrol. This way, if the firmware rejects a data blob then the kernel will also reject it, instead of saving it for the next suspend/resume cycle. The old behaviour is that the kernel would save it anyway and on next firmware boot it would apply the previously-rejected configuration, leading to errors during playback. Additionally, the function also saves previously validated configurations, so that if the firmware does end up rejecting a new bytes value the kernel can send an old, previously-valid configuration.

ASoC: SOF: pcm: Add an option to skip platform trigger during stop

2023-04-20T11:51:59Z

In the case of IPC4, a pipeline is only paused during STOP/PAUSE/SUSPEND triggers and the FW keeps the host DMA running when a pipeline is paused. The start/stop tests iterate through STOP/START triggers without involving a hw_free. This means that the pipeline state will only toggle between PAUSED (during the STOP trigger) and RUNNING (during the START trigger). So this test should be treated in the same way as a PAUSE_PUSH/PAUSE_RELEASE test and the DMA should be kept running when toggling the pipeline states between PAUSED and RUNNING. Since there is no way to tell if a STOP trigger will be followed by hw_free or not, this patch proposes to always skip DMA stop during the STOP trigger and handle it later during hw_free. Introduce a new flag in struct sof_ipc_pcm_ops, delayed_platform_trigger, that will be used to ensure that the host DMA will not be stopped during the STOP/PAUSE/RELEASE triggers and set it for IPC4. The platform_trigger call to stop the DMA will be invoked during PCM hw_free instead when the pipeline is reset.
