Use the new IRQF_NO_AUTOEN flag when requesting the IRQ, rather then disabling it immediately after requesting it. This fixes a possible race where the IRQ might trigger between requesting and disabling it; and this also leads to a small code cleanup. Signed-off-by:

Merge series "Add support for on demand pipeline setup/destroy" from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: Hi, The previous, v2 of this series was sent by Daniel Baluta: https://lore.kernel.org/alsa-devel/20210917143659.401102-1-daniel.baluta@oss.nxp.com/ We have agreed that it might be better that someone from Intel is going to take it from here as we already have the infrastructure up to test and verify the dynamic pipelines support. Changes since v2 (sent by Daniel Baluta): - patch 10: Fix NULL point dereference in hda_dai_update_config() - I have kept Daniel's SoB for the series. Changes since v1: - Signed-off-by tag added by Daniel This series implements initial support for dynamic pipelines to setup/teardown pipeline as needed when a PCM is open/closed. Initially dynamic pipelines are only supported with single core setup which will be expanded with a follow-up series. Review with SOF community at https://github.com/thesofproject/linux/pull/2794 The feature has been merged on 1st of April to sof-dev, all issues found since has been fixed and squashed to this upstream series.

Implement SPDIF bypass mode. It implies internal SoC routing of SPDIF input signal to SPDIF output signal. The test bed requires two boards: B1 configured in bypass mode, and B2 to feed B1 SPDIF RX port and read B1 SPDIF TX port: B2 TX -> B1 RX, B2 RX <- B1 TX. The test procedure: a) Boot both boards b) B2: start "arecord <spdifcard> -r 48kHz | aplay <local DAC>" c) B2: start "aplay <spdifcard> -r 48kHz <2ch 48kHz audio file>" d) B1: enable bypass mode: amixer -cimxspdif cset numid=8,iface=PCM,name='Bypass Mode' on e) B2: check DAC audio, make sure the same sample rate is used at steps b) and c), in example above the rate is 48kHz. f) B1: try to run "aplay" or "arecord" on imxspdif card while in bypass mode - both must fail until bypass mode is disabled g) B1: disable bypass mode: amixer -cimxspdif cset numid=8,iface=PCM,name='Bypass Mode' off h) B1: check the usual playback and capture on imxspdif card. During this test try to set bypass mode - must not be allowed while playback or capture is running. Signed-off-by:

Add support for dynamic pipelines by modifying the PCM hw_params ioctl implementation to determine the widgets required for a PCM stream by querying the list of connected DAPM widgets. This list is saved as part of snd_sof_pcm_stream struct and will be used to setup the widgets. The sof_widget_list_setup/free routines setup and free connected DAPM widgets when a PCM is opened/closed. These routines accept a list of connected DAPM widgets as input and determine the SOF widgets, their corresponding pipeline widgets and connections between them that need to be setup before the PCM is triggered. Please note that the dynamic pipeline feature will only be enabled for those pipelines whose dynamic_pipeline_widget flag is set in topologies. Add a new token called SOF_TKN_SCHED_DYNAMIC_PIPELINE that when set in topology will be applied to the dynamic_pipeline_widget flag of the pipeline widget. Signed-off-by:

With the implementation of the dynamic pipeline feature, widgets will only be setup when a PCM is opened during the hw_params ioctl. The BE hw_params callback is responsible for sending the DAI_CONFIG for the DAI widgets in the DSP. With dynamic pipelines, the DAI widgets will need to set up first before sending the DAI_CONFIG IPC in the BE hw_params. Update the BE hw_params/hw_free callbacks for all ALH, HDA and SSP DAIs to set up/free the DAI widget before/after DAI_CONFIG IPC. Signed-off-by:

Add a new field, use_count to struct snd_sof_widget to keep track of the usage count for each widget. Since widgets can belong to multiple pipelines, this field will ensure that the widget is setup only when the first pipeline that needs it is started and freed when the last pipeline that needs it is stopped. There is no need to protect the widget use_count access as the core already handles mutual exclusion at the PCM level. Add a new helper sof_widget_free() to handle freeing the SOF widgets and export the sof_widget_setup/free() functions. Signed-off-by:

In preparation for supporting dynamic pipelines, move the widget setup, DAI config IPCs to the complete callback during topology loading. For current topology where all the pipelines are static, all the pipelines will be set up during complete. For topologies with dynamic and static pipelines, this will enable setting up only the static ones during topology loading. Reuse the sof_restore_pipelines() function for this purpose and rename it to sof_set_up_pipelines(). Signed-off-by:

Add two new fields to save the source widget and sink widget pointers in struct snd_sof_route to make it easier to look up routes by source/sink widget. Also, add a flag to indicate if the route has been set up in the DSP. These will be used when the dynamic pipeline feature is implemented and routes will have to be set up at run time. Also, add a new sof_tear_down_pipelines() callback, that will used to reset the set up status for all routes during suspend. Signed-off-by:

Today, we set up all widgets required for all PCM streams at the time of topology parsing even if they are not used. An optimization would be to only set up the widgets required for currently active PCM streams. This would give the FW the opportunity to power gate unused memory blocks, thereby saving power. For dynamic pipelines, the widgets in the connected DAPM path for each PCM will need to be set up at runtime. This patch introduces a new token, DYNAMIC_PIPELINE, for scheduler type widgets that indicate whether a pipeline should be set up statically during topology load or at runtime when the PCM is opened. Introduce a new field called dynamic_pipeline_widget in struct snd_sof_widget to save the value of the parsed token. The token is set only for the pipeline (scheduler type) widget and must be propagated to all widgets in the same pipeline during topology load. Introduce another field called pipe_widget in struct snd_sof_widget that saves the pointer to the scheduler widget with the same pipeline ID as that of the widget. This field is populated when the pipeline completion callback is invoked during topology loading. Signed-off-by:

In the SOF driver, the operations performed in the complete callback can fail and therefore topology loading should return an error in such cases. So, change the signature of the complete op in struct snd_soc_tplg_ops to return an int to return the error. Also, amend the complete callback functions in the SOF driver and the SKL driver to conform with the new signature. Signed-off-by:

When the system resumes from S3, if the system plays a beep, there is continuous "Zizi.." noise from HP that could be heard. It is caused by the SAR mode switch during the combo jack re-detection which be executed parallelly in a workqueue after the system resumes. This patch changes the behavior of SAR mode switch to avoid this issue. Signed-off-by:

When codec's ASRC was enabled, the DA and AD filters use the reference clk which tracks the I2S clks. And if the I2S clks' timing of open and close are not expected, this patch allows the filters to switch to use sysclk if ASRC's ref clks disappeared and could fix the below possible issues: 1. Avoid DA filter to keep surplus samples. 2. Avoid that AD filter works failed during dapm's power on. For example, if I2S clks were closed before dacdat during playback off due to jack unplug, it causes ref clks disappeared and DA filter remained some samples which will produce pop noise on the next HP playback. ASRC auto-disable could clear the samples during the playback off. Signed-off-by:
