ASoC: SOF: Add flag and state which will be used for DSP-less mode

2023-04-04T11:42:33+00:00

The DSPless mode of the ASoC/SOF driver can be used for hardware
verification and debug on platforms with HDaudio codecs. The DSP mode is
still needed on existing platforms for SSP, DMIC, SoundWire interfaces
managed by the GP-DMA.

This mode is also helpful to compare the legacy HDaudio driver with the
ASoC/SOF driver wrt. codec management and handling. In theory we use the
same code but differences are sometimes seen on jack detection and event
handling.

ASoC: SOF: Add path definition for external firmware libraries

2022-10-21T12:05:03+00:00

IPC4 based firmware supports dynamically loaded external libraries.
The libraries will be not stored alongside of the firmware or tplg files.

For intel platforms the default path will be:
intel/avs-lib|sof-ipc4-lib// if a community key is used on the
given machine then the libraries will be under 'community' directory, like
it is done for the firmware itself.

ASoC: SOF: Drop the firmware and fw_offset from snd_sof_pdata

2022-10-21T12:04:58+00:00

The SOF stack now uses the sdev->basefw to work with the SOF firmware, the
information from plat_data can be dropped.

ASoC: SOF: Introduce function sof_of_machine_select

2022-08-23T17:22:29+00:00

From current design in sof_machine_check and snd_sof_new_platform_drv,
the SOF can only support ACPI type machine.

1. In sof_machine_check if there is no ACPI machine exist, the function
will return -ENODEV directly, that's we don't expected if we do not
base on ACPI machine.

2. In snd_sof_new_platform_drv the component driver need a driver name
to do ignore_machine, currently the driver name is obtained from
machine->drv_name, and the type of machine is snd_soc_acpi_mach.

So we add a new function named sof_of_machine_select that we can pass
sof_machine_check and obtain info required by snd_sof_new_platform_drv.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

2022-04-19T11:03:39+00:00

Now that we start having multiple platforms with minor variants, the
use of the const qualifier for 'dsp_ops' is starting to be
sub-optimal: the structures are copied across platforms, with only a
couple of members that differ.

This patch removes the const qualifier without any functionality
changes, and adds an optional initialization callback. In follow-up
patches, the dsp_ops will revisited for Intel HDaudio platforms, with
the differences added programmatically over a common baseline.

ASoC: SOF: add default IPC capability and file paths

2022-04-19T11:03:33+00:00

This patch adds a default IPC type for each platform, along with file
paths to be used for each IPC type. To make reviews simpler, we only
modify platform descriptors in this table, the information will be
used in the next patch.

The Intel IPCv4 is only supported on Intel platforms after APL, and
not by default. In follow-up patches, support for SKL and KBL will be
added, and in those two cases the IPCv4 will be the default (and only
supported mode).

ASoC: SOF: add path indirection to each IPC type

2022-04-19T11:03:32+00:00

With the addition of the IPCv4, we need the ability to select
different paths for firmware and topologies.

First add an indirection. Follow-up patches will add mechanisms to
select a default IPC or override it.

No functionality change in this patch.

ASoC: SOF: add definitions for different IPC types

2022-04-19T11:03:31+00:00

Add enum type to allow for different types of IPCs. The IPCv4 is
intended for Intel only as a convergence path with firmware used in
Windows. Follow-up patches will introduce different abstractions with
.ops and different search paths for firmware and topology files.
