[PATCH] ASoC: SOF: sof-audio: don't squelch errors in WIDGET_SETUP phase
by Peter Ujfalusi 08 Mar '23

08 Mar '23

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> When an IPC error happens while setting-up a widget during the FE hw_params phase, the existing logic will unwind all previous configurations but will overwrite the return status. The ALSA/ASoC logic will then proceed with the prepare and trigger phases, even though the firmware resources are not available. Fix by returning the initial error code and ignoring the code returned in the UNPREPARE phase.

[PATCH] ASoC: SOF: sof-audio: Fix broken early bclk feature for SSP
by Peter Ujfalusi 08 Mar '23

08 Mar '23

From: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> With the removal of widget setup during BE hw_params, the DAI config IPC is never sent with the SOF_DAI_CONFIG_FLAGS_HW_PARAMS. This means that the early bit clock feature required for certain codecs will be broken. Fix this by saving the config flags sent during BE DAI hw_params and reusing it when the DAI_CONFIG IPC is sent after the DAI widget is set up. Also, free the DAI config before the widget is freed. The DAI_CONFIG IPC sent during the sof_widget_free() does not have the DAI index information. So, save the dai_index in the config during hw_params and reuse it during hw_free. For IPC4, do not clear the node ID during hw_free. It will be needed for freeing the group_ida during unprepare.
