ASoC: SOF: Implement snd_sof_bytes_ext_volatile_get kcontrol IO

2020-09-08T12:55:00+00:00

This patch implements the snd_sof_bytes_ext_volatile_get() to read the actual parameters from DSP by sending the SOF_IPC_COMP_GET_DATA IPC for the kcontrol of type SOF_TPLG_KCTL_BYTES_VOLATILE_RO.

ASoC: SOF: support topology components on secondary cores

2020-09-04T09:12:22+00:00

Currently SOF supports running pipelines on secondary DSP cores in a limited way. This patch represents the next step in SOF multi-core DSP support, it adds checks for core ID to individual topology components. It takes care to power up all the requested cores. More advanced DSP core power management should be added in the future.

ASoC: SOF: Update correct LED status at the first time usage of update_mute_led()

2020-05-01T11:27:17+00:00

At the first time update_mute_led() gets called, if channels are already muted, the temp value equals to led_value as 0, skipping the following LED setting. So set led_value to -1 as an uninitialized state, to update the correct LED status at first time usage.

ASoC: SOF: fix uninitialised "work" with VirtIO

2020-03-26T18:31:14+00:00

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: pm: Introduce DSP power states

2020-02-11T11:48:04+00:00

Add a new enum sof_dsp_power_states for all the possible the DSP device states. The SOF driver currently handles only the D0 and D3 states and support for other states will be added later as needed. Also, add a helper to determine the target DSP power state based on the system suspend target. The snd_sof_dsp_d0i3_on_suspend() function is renamed to snd_sof_stream_suspend_ignored() to be more indicative of what it does and it used to determine the target DSP state during system suspend.

ASoC: SOF: Make creation of machine device from SOF core optional

2019-12-09T18:39:35+00:00

Currently, SOF probes machine drivers by creating a platform device and passing the machine description as private data. This is driven by the ACPI restrictions. Ideally, ACPI tables should contain the description for the machine driver. This is not possible because ACPI tables are frozen and used on multiple OS-es (e.g Windows). In the case of Device Tree we don't have this restriction, so we choose to probe the machine drivers by creating a DT node as is the standard ALSA way. This patch makes the probing of machine drivers from SOF core optional allowing for Device Tree platforms to decouple the SOF core from machine driver probing. Along with this, it also consolidates the machine driver selection for Intel platforms by defining optional ops for selecting the machine driver based on the ACPI match for HDA and non-HDA platforms and setting the mach params.
