ASoC: SOF: Introduce generic names for IPC types

2024-05-17T10:01:59+00:00

[ Upstream commit 6974f2cd2fa94fef663133af23722cf607853e22 ] Change the enum names for the IPC types to be more descriptive and drop tying the IPC4 to Intel SoCs. Add defines to avoid build breakage while the related code is modified to use the new enum names.

ASoC: SOF: Pass PCI SSID to machine driver

2023-11-28T17:19:42+00:00

[ Upstream commit ba2de401d32625fe538d3f2c00ca73740dd2d516 ] Pass the PCI SSID of the audio interface through to the machine driver. This allows the machine driver to use the SSID to uniquely identify the specific hardware configuration and apply any platform-specific configuration. struct snd_sof_pdata is passed around inside the SOF code, but it then passes configuration information to the machine driver through struct snd_soc_acpi_mach and struct snd_soc_acpi_mach_params. So SSID information has been added to both snd_sof_pdata and snd_soc_acpi_mach_params. PCI does not define 0x0000 as an invalid value so we can't use zero to indicate that the struct member was not written. Instead a flag is included to indicate that a value has been written to the subsystem_vendor and subsystem_device members. sof_pci_probe() creates the struct snd_sof_pdata. It is passed a struct pci_dev so it can fill in the SSID value. sof_machine_check() finds the appropriate struct snd_soc_acpi_mach. It copies the SSID information across to the struct snd_soc_acpi_mach_params. This done before calling any custom set_mach_params() so that it could be used by the set_mach_params() callback to apply variant params. The machine driver receives the struct snd_soc_acpi_mach as its platform_data.

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: 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).
