Crash happens in snd_soc_dapm_new_dai() when substream->private_data access is made and substream is NULL here. This is seen for DAIs where only playback or capture stream is defined. This seems to be happening for codec2codec DAI link. Both playback and capture are 0 during soc_new_pcm(). This is probably happening because cpu_dai and codec_dai are both validated either for SNDRV_PCM_STREAM_PLAYBACK or SNDRV_PCM_STREAM_CAPTURE. Shouldn't be playback = 1 when, - playback stream is available for codec_dai AND - capture stream is available for cpu_dai and vice-versa for capture = 1? Signed-off-by:

For some reason, attempting to route audio through QDSP6 on MSM8916 causes the RX interpolation path to get "stuck" after playing audio a few times. In this situation, the analog codec part is still working, but the RX path in the digital codec stops working, so you only hear the analog parts powering up. After a reboot everything works again. So far I was not able to reproduce the problem when using lpass-cpu. The downstream kernel driver avoids this by resetting the RX interpolation path after use. In mainline we do something similar for the TX decimator (LPASS_CDC_CLK_TX_RESET_B1_CTL), but the interpolator reset (LPASS_CDC_CLK_RX_RESET_CTL) got lost when the msm8916-wcd driver was split into analog and digital. Fix this problem by adding the reset to msm8916_wcd_digital_enable_interpolator().

MIC BIAS External1 sets pm8916_wcd_analog_enable_micbias_ext1() as event handler, which ends up in pm8916_wcd_analog_enable_micbias_ext(). But pm8916_wcd_analog_enable_micbias_ext() only handles the POST_PMU event, which is not specified in the event flags for MIC BIAS External1. This means that the code in the event handler is never actually run. Set SND_SOC_DAPM_POST_PMU as the only event for the handler to fix this.

In case system has multiple HDA controllers, it can happen that same HDA codec driver is used for codecs of multiple controllers. In this case, SOF may fail to probe the HDA driver and SOF initialization fails. SOF HDA code currently relies that a call to request_module() will also run device matching logic to attach driver to the codec instance. However if driver for another HDA controller was already loaded and it already loaded the HDA codec driver, this breaks current logic in SOF. In this case the request_module() SOF does becomes a no-op and HDA Codec driver is not attached to the codec instance sitting on the HDA bus SOF is controlling. Typical scenario would be a system with both external and internal GPUs, with driver of the external GPU loaded first. Fix this by adding similar logic as is used in legacy HDA driver where an explicit device_attach() call is done after request_module(). Also add logic to propagate errors reported by device_attach() back to caller. This also works in the case where drivers are not built as modules. Signed-off-by:

In current driver, locks can be taken as follows: - Register access: take a lock on regmap config and then on clock. - Master clock provider: take a lock on clock and then on regmap config. This can lead to the circular locking summarized below. Remove peripheral clock management through regmap framework, and manage peripheral clock in driver instead. On register access, lock on clock is taken first, which allows to avoid possible locking issue.

dsp_box is used to keep DSP initiated messages. The value of dsp_offset is set by the DSP with the first message, so we need a way to bootstrap it in order to get the first message. We do this by setting the correct default dsp_box offset which on i.MX8 is not zero. Very interesting is why it has worked until now. On i.MX8, DSP communicates with ARM core using a shared SDRAM memory area. Actually, there are two shared areas: * SDRAM0 - starting at 0x92400000, size 0x800000 * SDRAM1 - starting at 0x92C00000, size 0x800000 SDRAM0 keeps the data sections, starting with .rodata. By chance fw_ready structure was placed at the beginning of .rodata. dsp_box_base is defined as SDRAM0 + dsp_box_offset and it is placed at the beginning of SDRAM1 (dsp_box_offset should be 0x800000). But because it is zero initialized by default it points to SDRAM0 where by chance the fw_ready was placed in the SOF firmware. Anyhow, SOF commit 7466bee378dd811b ("clk: make freq arrays constant") fw_ready is no longer at the beginning of SDRAM0 and everything shows how lucky we were until now. Fix this by properly setting the default dsp_box offset. Fixes: 202acc56 ("ASoC: SOF: imx: Add i.MX8 HW support") Signed-off-by:Daniel Baluta <daniel.baluta@nxp.com> Signed-off-by:

The error path of soc_new_pcm_runtime() invokes soc_free_pcm_runtime() that may cause a few problems. First off, it calls list_del() for rtd->list that may not be initialized. Similarly, snd_soc_pcm_component_free() traverses over the component list that may not be initialized, either. Such access to the uninitialized list head would lead to either a BUG_ON() or a memory corruption.

When the PCM_PARAM IPC fails while configuring the FE, the kernel oopses in the HDaudio link DMA .hw_free operation. The root cause is a NULL dma_data since the BE .hw_params was never called by the SOC core. This error can also happen if the HDaudio link DMA configuration IPC fails in the BE .hw_params. This patches makes sure the dma_data is properly saved in .hw_params, and tested before being use in hw_free. GitHub issue: https://github.com/thesofproject/linux/issues/1417Reviewed-by:

If sof_machine_check() fails during driver probe, the IPC state is not initialized and this will lead to a NULL dereference at driver unload. Example log is as follows: [ 1535.980630] sof-audio-pci 0000:00:1f.3: error: no matching ASoC machine driver found - aborting probe [ 1535.980631] sof-audio-pci 0000:00:1f.3: error: failed to get machine info -19 [ 1535.980632] sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -19 [ 1550.798373] BUG: kernel NULL pointer dereference, address: 0000000000000008 ...

On CML boards with the RT5682 headset codec and RT1011 speaker amplifier, the platform firmware exposes three ACPI HIDs (10EC5682, 10EC1011 and MX98357A). The last HID is a mistake in DSDT tables, which causes the wrong machine driver to be loaded. This patch changes the key used to identify boards and changes the order of entries in the table to load the correct machine driver. The order does matter and should not be modified to work-around this firmware issue. Signed-off-by:

An error occurs during parsing more than one ext_data from the mailbox, because of invalid data offset handling. Fix by removing the incorrect duplicate increment of the offset. The return value is also reset in the switch case. This does not change the behavior but improves readability - there is no longer a need to check what the return value of get_ext_windows is.

In normal sound case all DAIs are detected as CPU-Codec. simple_dai_link_of supports the presence of a platform but it counts it as a CPU DAI resulting in the creation of an extra link. Adding a platform property to a link description like: simple-audio-card,dai-link { cpu { sound-dai = <&sai1>; }; plat { sound-dai = <&dsp>; }; codec { sound-dai = <&wm8960>; } will result in the creation of two links: * sai1 <-> wm8960 * dsp <-> wm8960 which is obviously not what we want. We just want one single link with: * sai1 <-> wm8960 (and platform set to dsp). Signed-off-by: -

The return value of soc_tplg_pcm_create() is currently not checked in soc_tplg_pcm_elems_load(). If an error is to occur there, the topology ignores it and continues loading. Fix that by checking the status and rejecting the topology on error. Reviewed-by:

snd_soc_add_dai_link() might fail. This situation occurs for instance in a very specific use case where a PCM device and a Back End DAI link are given identical names in the topology. When this happens, soc_new_pcm_runtime() fails and then snd_soc_add_dai_link() returns -ENOMEM when called from soc_tplg_fe_link_create(). Because of that, the link will not get added into the card list, so any attempt to remove it later ends up in a panic. Fix that by checking the return status and free the memory in case of an error.
