2022-02-09ASoC: SOF: Intel: hdac_ext_stream: consistent prefixes for variables/membersPierre-Louis Bossart1-61/+61
The existing code maximizes confusion by using 'stream' and 'hstream' variables of different types, e.g: struct hdac_stream *stream; struct hdac_ext_stream *stream; struct hdac_stream *hstream; struct hdac_ext_stream *hstream; This confusion is partly inherited from legacy code but SOF contributors added their own creative spin, e.g. struct hdac_ext_stream *link_dev; struct hdac_ext_stream *dsp_stream; struct hdac_ext_stream hda_stream; and my personal favorite: stream = &hda_stream->hda_stream; This patch suggests a consistent naming across all Intel code related to HDAudio stream management. The convention is - by hierarchical order: struct sof_intel_hda_stream *hda_stream; struct hdac_ext_stream *hext_stream; struct hdac_stream *hstream; No functionality change - just renaming of variables/members.

2021-12-13ASoC: SOF: Intel: hda-stream: limit PROCEN workaroundPierre-Louis Bossart1-6/+12
The work-around enabled in hda-stream.c is only required on earlier versions of SOCs/PCH (Skylake, KabyLake, ApolloLake, GeminiLake). Before setting the format on the host DMA, it is required to couple the host and link DMA - which as a consequence shall use the same format. This patch introduces a quirk field in the platform descriptor and makes the work-around conditional. Newer platforms have no limitations on the use of host and link DMA, which can use different formats.

2021-11-24ASoC: SOF: Intel: add .ack support for HDaudio platformsRanjani Sridharan1-0/+2
When we disable rewinds, then the .ack can be used to program SPIB with the application pointer, which allows the HDaudio DMA to save power by opportunistically bursting data transfers when the path to memory is enabled (and conversely to shut it down when there are no transfer requests). The SPIB register can only be programmed with incremental values with wrap-around after the DMA RUN bits are set. For simplicity, we set the INFO_NO_REWINDS flag in the .open callback when we already need to program the SNDRV_PCM_INFO_SYNC_APPLPTR flag. Rewinds are not used by many applications. One notable application using rewinds is PulseAudio. Practical experiments with Ubuntu/PulseAudio default settings did not show any audible issues, but the user may hear volume changes and notification with a delay, depending on the size of the ring buffer and latency constraints. The choice of disabling rewinds is exposed as a kernel parameter and not a Kconfig option to avoid any undesirable side-effects.

Now, any non-pcm operation e.g.: compress can mistakenly make use of that pointer as it's bypassing all "if (s->substream)" checks.

2019-12-09ASoC: SOF: Intel: hda: solve MSI issues by merging ipc and stream irq handlersBard Liao1-9/+11
The existing code uses two handlers for a shared edge-based MSI interrupts. In corner cases, interrupts are lost, leading to IPC timeouts. Those timeouts do not appear in legacy mode. This patch merges the two handlers and threads into a single one, and simplifies the mask/unmask operations by using a single top-level mask (Global Interrupt Enable). The handler only checks for interrupt sources using the Global Interrupt Status (GIS) field, and all the actual work happens in the thread. This also enables us to remove the use of spin locks. Stream events are prioritized over IPC ones. This patch was tested with HDaudio and SoundWire platforms, and all known IPC timeout issues are solved in MSI mode. The SoundWire-specific patches will be provided in follow-up patches, where the SoundWire interrupts are handled in the same thread as IPC and stream interrupts.
