ALSA/ASoC: include: clarify Copyright information

2024-05-09T18:26:34+00:00

For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.

Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

ASoC: SOF: ipc3-topology: use old pipeline teardown flow with SOF2.1 and older

2022-11-01T18:28:07+00:00

Originally in commit b2ebcf42a48f ("ASoC: SOF: free widgets in
sof_tear_down_pipelines() for static pipelines"), freeing of pipeline
components at suspend was only done with recent FW as there were known
limitations in older firmware versions.

Tests show that if static pipelines are used, i.e. all pipelines are
setup whenever firmware is powered up, the reverse action of freeing all
components at power down, leads to firmware failures with also SOF2.0
and SOF2.1 based firmware.

The problems can be specific to certain topologies with e.g. components
not prepared to be freed at suspend (as this did not happen with older
SOF kernels).

To avoid hitting these problems when kernel is upgraded and used with an
older firmware, bump the firmware requirement to SOF2.2 or newer. If an
older firmware is used, and pipeline is a static one, do not free the
components at suspend. This ensures the suspend flow remains backwards
compatible with older firmware versions. This limitation does not apply
if the product configuration is updated to dynamic pipelines.

The limitation is not linked to firmware ABI, as the interface to free
pipeline components has been available already before ABI3.19. The
problem is in the implementation, so firmware version should be used to
decide whether it is safe to use the newer flow or not. This patch adds
a new SOF_FW_VER() macro to compare SOF firmware release versions.

ASoC: SOF: add _D3_PERSISTENT flag to fw_ready message

2022-01-24T13:31:14+00:00

Add a bit definition to the fw_ready message, to denote if the FW
supports the IMR (Isolated Memory Region) restoring feature.

If the bit is set, the driver can skip downloading the firmware again
during system resume or runtime resume.

Bump the ABI version to 3.19 to make it aligned with FW side.

ASoC: SOF: IPC: make sof_ipc_window monosized

2020-08-26T11:44:07+00:00

This step is needed to add possibility to pack sof_ipc_window inside
another one in used FW build tools - for example in extended manifest.
Structure reusability leads to easy parsing function reuse, so source
code is shorter and easier to maintain.

Using structures with constant size is less tricky and properly
supported by each toolchain by contrast to variable size elements.

This is minor ABI change - backward compatibility is kept.

ASoC: SOF: make sof_ipc_cc_version to fixed length

2020-04-15T23:23:10+00:00

Align struct sof_ipc_cc_version to firmware definition in SOF ABI 3.15.0.

The struct definition was changed due to errors in FW build.
The Cadence XCC compiler produces incorrect linkage section sizes, when a
variable length array is used in the compiler version struct. The firmware
definition was changed to a fixed 32 byte compiler description string.
This length covers all released firmware binaries and thus only a minor
ABI change is needed.

As the same structure is used in IPC messages between driver and firmware,
the kernel needs to be aligned to firmware change.
