[PATCH 0/6] ASoC: SOF: Clean up the probe support
Hi,
The probe debug feature of SOF can be used to extract streams of data from a given point of a pipeline for analysis.
The support is implemented by using the ALSA/ASoC compress support for the capture stream, but the code can not be used by/for a normal compressed data stream. It is a debug feature.
Merge the probe implementation in the core (compress.c/h and probe.c/h) into one file: sof-probes.c/h
Rename the Intel HDA specific probe implementation from hda-compressc.c to hda-probes.c
We also need to add IPC logging support for the probes messages and drop the unused references to SOF compress to have reasonably clean code.
Regards, Peter --- Peter Ujfalusi (5): ASoC: SOF: ipc: Add probe message logging to ipc_log_header() ASoC: SOF: pcm: Remove non existent CONFIG_SND_SOC_SOF_COMPRESS reference ASoC: SOF: probe: Merge and clean up the probe and compress files ASoC: SOF: Intel: Rename hda-compress.c to hda-probes.c ASoC: SOF: sof-probes: Correct the function names used for snd_soc_cdai_ops

Probe related messages are missing from the logging, for example the PROBE_INIT would show up as:
ipc tx: 0xc0010000: unknown GLB command ipc tx succeeded: 0xc0010000: unknown GLB command
Add code to handle the probe messages to have human readable output

The SND_SOC_SOF_COMPRESS is not valid Kconfig option, remove it.
At the same time remove the also the declaration of the non existent sof_compressed_ops.

From: Ranjani Sridharan ranjani.sridharan@linux.intel.com
sof_probe_compr_ops are not platform-specific. So move it to common compress code and export the symbol. The compilation of the common compress code is already dependent on the selection of CONFIG_SND_SOC_SOF_DEBUG_PROBES, so no need to check the Kconfig section for defining sof_probe_compr_ops again.

The probe debug functionality is implemented via compress support and it was spread across two set of files: probe.c/h compress.c/h
Merge the two files into sof-probes.s/h and clean them up by removing unused struct definitions, functions. We can also move most of the functions static as they are only used internally.

The hda-compress.c is implementing the SOF probe support for intel HDA platforms using compress API.
To avoid the confusion, rename it to reflect this.

The probe debug feature of SOF can be used to extract streams of data from a given point of a pipeline for analysis.
The support is implemented by using the ALSA/ASoC compress support for the capture stream, but the code can not be used by/for a normal compressed data stream. It is a debug feature.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
