ASoC: SOF: make struct snd_sof_dai IPC agnostic

2022-03-09T13:30:09Z

Remove the comp_dai and dai_config members of struct snd_sof_dai and replace it with a void *private field. Introduce a new struct sof_dai_private_data that will contain the pointer to these two fields. The topology parser will populate this structure and save it as part of the "private" member in snd_sof_dai. Change all users of these fields to use the private member instead.

ASoC: SOF: IPC: dai: Expand DAI_CONFIG IPC flags

2021-11-26T13:24:24Z

Some DAI components, such as HDaudio, need to be stopped in two steps a) stop the DAI component b) stop the DAI DMA This patch enables this two-step stop by expanding the DAI_CONFIG IPC flags and split them into 2 parts. The 4 LSB bits indicate when the DAI_CONFIG IPC is sent, ex: hw_params, hw_free or pause. The 4 MSB bits are used as the quirk flags to be used along with the command flags. The quirk flag called SOF_DAI_CONFIG_FLAGS_2_STEP_STOP shall be set along with the HW_PARAMS command flag, i.e. before the pipeline is started so that the stop/pause trigger op in the FW can take the appropriate action to either perform/skip the DMA stop. If set, the DMA stop will be executed when the DAI_CONFIG IPC is sent during hw_free. In the case of pause, DMA pause will be handled when the DAI_CONFIG IPC is sent with the PAUSE command flag. Along with this, modify the signature for the hda_ctrl_dai_widget_setup/ hda_ctrl_dai_widget_free() functions to take additional flags as an argument and modify all users to pass the appropriate quirk flags. Only the HDA DAI's need to pass the SOF_DAI_CONFIG_FLAGS_2_STEP_STOP quirk flag during hw_params to indicate that it supports two-step stop and pause.

ASoC: SOF: dai: include new flags for DAI_CONFIG

2021-10-05T12:08:11Z

Mirror changes done in SOF tree. The changes do not rely on BIT/GENMASK on purpose to keep the structure and flags common with the firmware tree. The DAI_CONFIG IPC is currently used in multiple ways. It is sent to the DSP firmware when enabling static or dynamic pipelines, in hw_params or prepare callbacks for Intel SSP, HDaudio and ALH, on trigger_stop and hw_free. This IPC has been abused a bit in the past, i.e. the values used for some of the DAI-specific fields are used to either allocate or free resources. Two typical examples are Intel HDaudio and SoundWire/ALH DAIs, where using a zero DMA channel number or stream tag signals to the firmware the DMA channels or tags allocated earlier can be freed. Rather than add a new IPC for 'hw_params' and 'hw_free', this patch suggests supporting a 2-bit value conveying the 'stage' information in an existing IPC structure. Only 3 possible values are used. The mapping between HW_PARAMS and HW_FREE flags and ALSA definitions is not strictly 1:1, e.g. in some cases the HW_PARAM flag might be set during the .prepare callback, while the HW_FREE might be sent during the ALSA .trigger for stop/suspend. The semantics of the flags is to reserve and start/stop all needed resources, typically hardware related such as DMAs or clocks, when the HW_PARAMS is set, while the HW_FREE flag allows the firmware to release the resources allocated. The data transfers are still controlled within the firmware through the propagation of the trigger command. The driver can then pass information that the DAI_CONFIG was invoked in e.g. a pipeline/DAI setup, hw_params or hw_free stage without having to use a special DAI-specific encoding. Unfortunately we can't remove old encodings due to backwards-compatibility requirements but for new cases, such as the SSP in follow-up patches, we can make the IPC less cryptic. This change is tagged as ABI 3.19 and is completely backwards compatible.
