Caller already checks if hdr_pos is behind EOF, before calling soc_tplg_valid_header(), so there is no need to recheck it again. This also allows to remove behaviour of return 0 - forcing the caller to break out of while loop. Reviewed-by:

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The following series will enable multi-stream support for playback and capture streams. Currently only a single PCM can be connected to a DAI, with the multi-stream support it is possible to connect multiple PCMs to a single DAI. To achieve this we need to make sure that DAIs/AIF are only set up once since other stream could be connected to it later. We also need to introduce reference or use counting for widgets to make sure that they are not going to be destroyed while other streams are still using them. With the multi-stream support we also need to extend our current locking scheme which worked well for simple paths.

Merge series from Astrid Rost <astrid.rost@axis.com>: Add a generic way to create jack inputs for auxiliary jack detection drivers (e.g. via i2c, spi), which are not part of any real codec. The simple-card can be used as combining card driver to add the jacks, no new one is required. Create a jack (for input-events) for jack devices in the auxiliary device list (aux_devs). A device which returns a valid value on get_jack_type counts as jack device; set_jack is required to add the jack to the device.

If the pipeline setup fails at the first widget/pipeline then we will have no spipe stored under the pipeline_list->pipelines, the pipeline_list->count is 0. If this is the case we would have a NULL pointer dereference if the execution is allowed to proceed. Check for this condition along with the pipeline_list->pipelines check Signed-off-by:

The use_count of the swidget is protect by ALSA core PCM locking with the exception when an associated kcontrol is changed. It has been observed that a rightly timed kcontrol access during stream stop can result of an attempt to send a control update to a widget which has been freed up between the check of the use_count and the message sending. We need to protect the entire sof_widget_setup() and sof_widget_free() execution to make it safe to rely on the use_count. Move the code under an _unlocked() function and use a mutex to protect the execution of the functions for concurrency. On the control path we need to use the lock only for the kcontrol access, the widget_kcontrol_setup() op is called with the lock already held. Reported-by:

When starting/stopping multiple streams in parallel, pipeline triggers and pipeline frees can get interleaved. So use the same mutex used for pipeline trigger to protect the pipeline frees as well. Rename the trigger_mutex to pipeline_state_mutex for more clarity. Signed-off-by:

Use the started_count and paused_count to implement reference counting when making decisions to start/stop/pause pipelines during the FE DAI trigger. This is necessary to trigger the shared pipelines in the FE DAI trigger properly. With IPC4, the FE trigger will issue multiple pipeline state changes, and the triggers are propagated downstream to connected pipelines by the SOF driver - not the firmware. This creates a window for race conditions where an FE trigger preempts another one, which results in inconsistent pipeline states and refcounts. This patch introduces a mutex lock for the pcm trigger that guarantees that IPC4 state and resources are accessed in a serialized manner. Signed-off-by:

Add a new flag, skip_during_fe_trigger, to struct sof_ipc4_pipeline to skip triggering pipelines in the FE DAI trigger. Set this flag for the HDA DAI BE pipelines so that their BE pipeline will not be triggered in the FE DAI trigger. Also, move the trigger handling for all commands include START/PAUSE_RELEASE for the HDA DAI's to the backend DAI trigger ops. For the SSP/DMIC/SDW cases, remove the BE DAI trigger as they involve no DMA operations and can be triggered in the FE DAI trigger. This is in preparation to perform batch triggering of all pipelines for the non-HDA case. Signed-off-by:

IPC3 and IPC4 have different requirements for the order in which the FE CPU and BE CPU DAI trigger callbacks must be invoked. With a regular PCM start/stop, pipeline widgets are set up during hw_params and freed during hw_free. But when the system is suspended when a PCM is running, pipeline widgets are freed during the SUSPEND trigger callback for the FE CPU DAI. In order to avoid freeing the pipeline widgets before the BE CPU DAI trigger is executed, the trigger order was modified in previous contributions in the PCM dai_link_fixup callback to make sure that the BE CPU DAI trigger stop/suspend is always invoked before the FE CPU DAI trigger. But this contradicts the firmware requirement for IPC4 w.r.t. ordering of pipeline triggers. So, remove the freeing of pipeline widgets during FE CPU DAI suspend trigger and handle it during system suspend when the tear_down_all_pipelines() IPC op is invoked. This will be followed up with a patch to fix the trigger order for IPC4. Signed-off-by:

When walking the list of the widgets from the source to the sink, we accidentally also end up preparing/setting up the widgets that are not in the list of connected DAPM widgets associated with the PCM.
