ASoC: SOF: fix uninitialised "work" with VirtIO

2020-03-26T18:31:14Z

In the VirtIO case the sof_pcm_open() function isn't called on the host during guest streaming, which then leaves "work" structures uninitialised. However it is then used to handle position update messages from the DSP. Move their initialisation to immediately after allocation of the containing structure.

ASoC: SOF: pcm: skip DMA buffer pre-allocation

2020-03-02T14:13:47Z

As discussion in ALSA https://patchwork.kernel.org/patch/11336023/, it is suggested to skip DMA buffer pre-allocation with passing size=0 when calling snd_pcm_set_managed_buffer(), to make the full buffer_bytes range configured in topology file selectable from user space, here do the corresponding change in SOF PCM driver to implement it. This change doesn't have dependency to the change that Takashi will do in the ALSA core by adding total_pcm_alloc_bytes limitation to the struct snd_card, it passes tests both with or without Takashi's coming change on SOF CML platform.

ASoC: SOF: Intel: Add Probe compress CPU DAIs

2020-02-18T21:52:11Z

Declare extraction CPU DAI as well as sof_probe_compr_ops. FE DAIs can link against these new CPU DAI to create new compress devices.

ASoC: SOF: Add system_suspend_target field to struct snd_sof_dev

2020-02-11T11:48:03Z

Add the system_suspend_target field to struct snd_sof_dev to track the intended system suspend power target. This will be used as one of the criteria for determining the final DSP power state.

ASoC: SOF: fix an Oops, caused by invalid topology

2020-01-27T17:51:49Z

It is possible to create invalid topology that will cause a kernel Oops when trying to allocate buffers for a NULL substream. Specifically such an Oops was caused by a topology, where a DAI on a capture pipeline was referencing the PCM ID from a playback pipeline. Fix the Oops by explicitly checking for NULL.

ASoC: SOF: fix PCM playback through ALSA OSS emulation

2020-01-13T15:00:00Z

Any app using ALSA OSS emulation on top of SOF will fail to error from OSS SNDCTL_DSP_SETFMT ioctl. Reported initially as an issue with xournalpp (application using PortAudio with an OSS backend), but applies more generally to other apps using OSS as well. Problem is caused by SOF PCM not supporting repeated calls to hw_params(), without matching calls to pcm_free(). This is however exactly what the ALSA OSS PCM code is doing when it is handling the OSS ioctls. The problem will lead to leaking of DSP resources and eventual failure of DSP PCM_PARAMS IPC.

ASoC: SOF: partition audio-related parts from SOF core

2019-12-09T18:38:57Z

Move all the audio-specific code in the core, audio-specific logic in the top-level PM callbacks and the core header files into a separate file (sof-audio.*) in preparation for adding an audio client device. In the process of moving all structure definitions for widget, routes, pcm's etc, the snd_sof_dev member in all these structs is replaced with the snd_soc_component member. Also, use the component device instead of the snd_sof_dev device wherever possible in the PCM component driver, control IO functions and the topology parser as the component device will be moved over to the client device later on.
