Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: With additional tests with the introduction of a 'deep-buffer' PCM device mixed with the regular low-latency path, we came up with two improvements in the BE state machine and transitions. The short explanation is that the BE cannot directly use the trigger commands provided by the FE, and a translation is needed to deal with paused states.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: The INTEL_IPC4 protocol and firmware architecture will rely on different sets of firmware binary and topology files. Some platforms will only support INTEL_IPC4, some will support both INTEL_IPC4 and SOF_IPC for development, and some will stay with the existing SOF_IPC. This patchset adds new IPC definitions, and search paths for firmware and topology files, along with means to override the default IPC type and search paths for development. The firmware binary names are aligned with those used by the Intel AVS driver to avoid duplicate firmware installs, but the topology will have to differ due to driver architecture differences.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: A continuation of avs-driver initial series [1]. This chapter covers path management and topology parsing part which was ealier path of the main series. The two patches that represented these two subjects in the initial series, have been split into many to allow for easier review and discussion. AVS topology is split into two major parts: dictionaries - found within ASoC topology manifest - and path templates. Dictionaries job is to reduce the total amount of memory occupied by topology elements. Rather than having every pipeline and module carry its own information, each refers to specific entry in specific dictionary by provided (from topology file) indexes. In consequence, most struct avs_tplg_xxx are made out of pointers. Path templates are similar to path descriptions found in skylake-driver and they describe how given path shall look like in runtime - number of modules and pipelines that shape it and how they are laid out. A single path template is tied either to FE or BE and thus at most to a single, user-visible endpoint when speaking of FE. Path is a software representation of its ADSP firmware equivalent. It's a logical container for pipelines which are themselves containers - this time for modules i.e. processing units. Depending on the number of audio formats supported, each path template may carry one or more descriptions of given path. During runtime, when audio format is known, description matching said format is selected and used when instantiating path on ADSP firmware side through IPCs.

Commit 3aa1e96a ("ASoC: soc-pcm: fix BE handling of PAUSE_RELEASE") did not modify the existing logic and kept the same logic for the following transition play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is STOP <<< !! release FE1 -> BE state is START stop FE1 -> BE state is STOP At the time it was identified by reviewers that a better solution might consist in play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is PAUSE <<< !! release FE1 -> BE state is START stop FE1 -> BE state is STOP This patch suggest a transition to PAUSE when all the 'active' streams are paused. This would allow for a more consistent resource management for platforms where PAUSE and STOP are handled differently. To track the special case of an FE going from PAUSE_PUSH to STOP, we add a state variable for each FE context. This 'fe_pause' boolean is set on PAUSE_PUSH and cleared on either PAUSE_RELEASE and STOP triggers. Signed-off-by:

SND_SOC_SOF_HDA_PROBES must be tristate because the code it builds depends on code that is tristate. If SND_SOC_SOF_HDA_PROBES is bool it leads to the following build inconsistency: SND_SOC_SOF_HDA_COMMON=m which selects SND_SOC_SOF_HDA_PROBES but since this is a bool SND_SOC_SOF_HDA_PROBES=y SND_SOC_SOF_HDA_PROBES=y selects SND_SOC_SOF_DEBUG_PROBES=y so sof-client-probes.c is built into the kernel. sof-client-probes.c calls functions in sof-client.c, but SND_SOC_SOF=m sof-client.c is built into a loadable module.

For the quality setting the quality setting register values are directly exposed to the kcontrol and thus to userspace. This is unfortunate because the register settings contains invalid bit combinations marked as "N/A". For userspace it doesn't make much sense to be able to set these just to see that the driver responds with "Please make sure you select a valid quality." in the kernel log. Work around this by adding get/set functions for the quality setting. Signed-off-by:

The reference manual has this for calculating the micfil internal clock divider: MICFIL Clock rate clkdiv = ----------------- 8 * OSR * outrate (with OSR == Oversampling Rate, outrate == output sample rate) The driver first sets the MICFIL Clock rate to (outrate * 1024) and then calculates back the clkdiv value from the above calculation. Simplify this by using a fixed clkdiv value of 8 and set the MICFIL Clock rate to (outrate * clkdiv * OSR * 8). While at it drop disabling the clock before setting its rate. The MICFIL module is disabled when the rate is changed and it is also resetted before it is started again, so I doubt it's necessary to disable the clock. Signed-off-by: -

get_pdm_clk() calculates the PDM clock based on the quality setting, but really the PDM clock is independent of the quality, it's always rate * 4 * micfil->osr. Just drop the function and do the calculation in the caller. Signed-off-by:

The micfil hardware provides the microphone data on multiple successive FIFO registers, one register per stereo pair. Also to work properly the SDMA_DONE0_CONFIG_DONE_SEL bit in the SDMA engines SDMA_DONE0_CONFIG register must be set. This patch provides the necessary information to the SDMA engine driver.

The i.MX SDMA engine can read from / write to multiple successive hardware FIFO registers, referred to as "Multi FIFO support". This is needed for the micfil driver and certain configurations of the SAI driver. This patch adds support for this feature. The number of FIFOs to read from / write to must be communicated from the client driver to the SDMA engine. For this the struct dma_slave_config::peripheral_config field is used. Signed-off-by:

Failed register accesses are really not expected in memory mapped registers. When it fails then the register access itself is likely not the reason, so no need to have extra error messages for each regmap access. Just drop the error messages.

All that the .set_sysclk hook in the micfil driver does is to pass the sysclk frequency to fsl_micfil_set_mclk_rate(). This function expects the sample rate as argument though, not any kind of sysclk frequency. The resulting rate setting of the clock is overwritten in hw_params anyway, so drop this altogether.

Add functions to ease with state changing of all objects found in the path. Each represents either a BIND/UNBIND or SET_PIPELINE_STATE IPC. DSP pipelines follow simple state machine scheme: CREATE -> RESET -> PAUSE -> RUNNING -> PAUSE -> RESET -> DELETE There is no STOP, PAUSE serves that purpose instead. Signed-off-by:

To implement ASoC PCM operations, DSP path handling is needed. With path template concept present, information carried by topology file can be converted into runtime path representation. Each may be composed of several pipelines and each pipeline can contain a number of processing modules inside. Number of templates and variants found within topology may vastly outnumber the total amount of pipelines and modules supported by AudioDSP firmware simultaneously (in runtime) so none of the IDs are specified in the topology. These are assigned dynamically when needed and account for limitations described by FIRMWARE_CONFIG and HARDWARE_CONFIG basefw parameters. Paths are created on ->hw_params() and are freed on ->hw_free() ALSA PCM operations. This choice is based on firmware expectations - need for complete set of information when attempting to instantiate pipelines and modules on AudioDSP side. With DMA and audio format provided, search mechanism tests all path variants available in given path template until a matching variant is found. Once found, information already available is combined with all avs_tplg_* pieces pointed by matching path variant. This finally allows to begin a cascade of IPCs which goal is to reserve resources and prepare DSP for upcoming audio streaming. Signed-off-by:
