ASoC: SOF: Add FW state to debugfs

2022-12-21T12:11:51Z

Allow system health detection mechanisms to check the FW state, this will allow them to check if the FW is in its "crashed" state going forward to help automatically diagnose driver state.

ASoC: SOF: debug: Fix potential buffer overflow by snprintf()

2022-08-05T11:57:23Z

snprintf() returns the would-be-filled size when the string overflows the given buffer size, hence using this value may result in the buffer overflow (although it's unrealistic). This patch replaces with a safer version, scnprintf() for papering over such a potential issue.

ASoC: SOF: debug: Clarify the IPC timeout handling path

2022-06-10T12:32:21Z

The dmesg log message of "Firmware exception" causes lots of confusion as the snd_sof_handle_fw_exception() is only called in case of an IPC tx timeout, where such a message does not make much sense. To not limit the snd_sof_handle_fw_exception() handler to just one error case, add a parameter to allow the caller to specify a meaningful message to be printed.

ASoC: SOF: Switch to IPC generic firmware tracing

2022-05-19T15:44:15Z

Introduce new, generic API for firmware tracing with sof_fw_trace_ prefix and switch to use it. At the same time the old IPC3 code can be dropped from trace.c, which is now a generic wrapper for the firmware tracing ops.

ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'

2022-04-19T11:03:39Z

Now that we start having multiple platforms with minor variants, the use of the const qualifier for 'dsp_ops' is starting to be sub-optimal: the structures are copied across platforms, with only a couple of members that differ. This patch removes the const qualifier without any functionality changes, and adds an optional initialization callback. In follow-up patches, the dsp_ops will revisited for Intel HDaudio platforms, with the differences added programmatically over a common baseline.

ASoC: SOF: Convert the generic probe support to SOF client

2022-02-10T15:19:12Z

Add a new client driver for probes support and move all the probes-related code from the core to the client driver. The probes client driver registers a component driver with one CPU DAI driver for extraction and creates a new sound card with one DUMMY DAI link with a dummy codec that will be used for extracting audio data from specific points in the audio pipeline. The probes debugfs ops are based on the initial implementation by Cezary Rojewski and have been moved out of the SOF core into the client driver making it easier to maintain. This change will make it easier for the probes functionality to be added for all platforms without having the need to modify the existing(15+) machine drivers.
