ASoC: SOF: Switch to IPC generic firmware tracing

2022-05-19T15:44:15+00:00

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: Rename dtrace_is_supported flag to fw_trace_is_supported

2022-05-19T15:44:12+00:00

Rename the internal flag to not limit it's use for dma-trace, but to be
used for generic firmware tracing functionality.

ASoC: SOF: Do not check for the fw_ready callback

2022-04-25T12:58:45+00:00

The fw_ready is handled internally to ipc3, the callback no longer in
use and it is going to be removed.

ASOC: SOF: pci: add ipc_type override for Intel IPC4 tests

2022-04-22T11:37:25+00:00

Add a kernel module parameter for select the non-default IPC type.

This should only be used by developers with access to firmware and
topology files, typically Intel and partners.

ASoC: SOF: Intel: hda: use common ops across platforms

2022-04-19T11:03:40+00:00

The dsp_ops are mostly common between platforms. Introduce a common
structure and an init function to set platform-specific values.

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

2022-04-19T11:03:39+00:00

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: simplify snd_sof_device_remove()

2022-03-08T12:27:40+00:00

The commit "ASoC: SOF: core: Unregister machine driver before IPC and
debugfs" moved the call to unregister the machine driver to be done
before freeing the IPC. With this change, we can safely move the call to
snd_sof_remove() inside the same if() block just above.

ASoC: SOF: core: unregister clients and machine drivers in .shutdown

2022-02-16T16:34:22+00:00

On a platform shutdown, the expectation for most drivers is that
userspace tasks will release all resources. When those sequences do
not complete, it can be the case that PCM devices exposed by ALSA
cards are used *after* the DSP shutdown completes, leading to a
platform hang.

When the clients and machine drivers provide an _unregister callback,
let's invoke it in the shutdown sequence.
