2021-11-25ASoC: SOF: Intel: hda-dai: fix potential locking issuePierre-Louis Bossart1-3/+4
[ Upstream commit a20f3b10de61add5e14b6ce4df982f4df2a4cbbc ] The initial hdac_stream code was adapted a third time with the same locking issues. Move the spin_lock outside the loops and make sure the fields are protected on read/write.

2021-05-19ASoC: SOF: Intel: hda: don't send DAI_CONFIG IPC for older firmwareRanjani Sridharan1-0/+5
BE hw_params op was recently added for SSP type DAIs. But sending the DAI_CONFIG IPC during hw_params is not supported with older firmware. So add an ABI check to avoid sending the IPC if the firmware ABI is older than 3.18.

2021-03-29ASoC: SOF: Intel: HDA: add hw params callback for SSP DAIsJaska Uimonen1-0/+44
Currently SSP DAIs don't have hw params callback function as there wasn't anything to setup after initial topology loading. After enabling multiple DAI configs the current config can be sent in the callback. This patch changes the way SSP config ipc is sent to the dsp. Before it was only sent once in topology loading, but now it will be additionally sent always when stream is opened. Mechanism is similar as with HDA DAIs.

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.

Move all the audio-specific code in the core, audio-specific logic in the top-level PM callbacks and the core header files into a separate file (sof-audio.*) in preparation for adding an audio client device. In the process of moving all structure definitions for widget, routes, pcm's etc, the snd_sof_dev member in all these structs is replaced with the snd_soc_component member. Also, use the component device instead of the snd_sof_dev device wherever possible in the PCM component driver, control IO functions and the topology parser as the component device will be moved over to the client device later on.

2019-07-23ASoC: SOF: Intel: hda: fix link DMA configRander Wang1-6/+9
For this bug, there are two capture pcm streams active, with one stream and its related stream tag released before suspend. Later when system suspend is done, the stream tag for the remaining active stream is released by SOF driver. After system resume, hda codec driver restores the stream tag for the active pcm stream, but SOF goes to assign a new one, which now doesn't match with the stream tag used by codec driver, and this causes DMA to fail receiving data, leading to unrecoverable XRUN condition in FW. For stream tag is stored in both hda codec and SOF driver, it shouldn't be released only in SOF driver. This patch just keeps the stream information in dma data and checks whether there is a stored DMA data for stream resuming from S3 and restores it. And it also removes DMA data when the stream is released. Tested on Whiskey Lake platform.

When application goes through SUSPEND/STOP->PREPARE->START cycle, we should always reprogram the DAI link DMA to ensure it is in sync with the host PCM DMA. Use same state tracking logic to handle both restart and system resume flows. Use link_prepared field of 'struct hdac_ext_stream' to store the state, instead of adding redundant fields to SOF specific structs.

2019-06-17ASoC: SOF: Intel: hda: reserve host DMA channel for hostless streamsRanjani Sridharan1-1/+10
Due to the HW programming sequence requirement that the host and link DMA channels need to be coupled/decoupled during pcm hw_params, the host DMA channel corresponding to the link DMA channel in use for hostless streams needs to be reserved. This is achieved by adding a host_reserved flag in the sof_intel_hda_stream structure which is checked when assigning a host DMA channel.

2019-06-17ASoC: SOF: Intel: hda: assign link DMA channel at run-timeRanjani Sridharan1-101/+183
The recommended HDA HW programming sequence for setting the DMA format requires that the link DMA and host DMA channels be coupled before setting the format. This change means that host DMA or link DMA channels be reserved even if only one is used. Statically assigned link DMA channels would mean that all the corresponding host DMA channels will need to be reserved, leaving only a few channels available at run-time. So, the suggestion here is to switch to dynamically assigning both host DMA channels and link DMA channels are run-time. The host DMA channel is assigned when the pcm is opened as before. While choosing the link DMA channel, if the host DMA channel corresponding to the link DMA channel is already taken, the proposed method checks to make sure that the BE is connected to the FE that has been assigned this host DMA channel. Once the link DMA channel is assigned, an IPC is sent to the DSP to set the link DMA channel. The link DMA channel is freed during hw_free() and also in the SUSPEND trigger callback. It will be re-assigned when hw_params are set upon resume.

2019-05-03ASoC: SOF: intel: hda: add hw_params_upon_resume flag for hda streamRanjani Sridharan1-9/+14
The prepare() ioctl for BE dai link gets called both when the stream is started and when it is resumed from suspend. SOF uses this ioctl to set the hw params again only if the stream has been suspended. When the stream is started, the hw_params ioctl gets called before prepare() and hw_params is set for the BE dai link. So the prepare call does not need to do anything further. When the stream resumes after system suspend, SOF requires that the hw_params be set again for the BE dai. In order to determine which streams should set the hw params during prepare(), an internal flag called "hw_params_upon_resume" is introduced in struct sof_intel_hda_stream. The flag is set for hda streams when the sof device suspends and is cleared after hw_params is set.
