ASoC: SOF: Intel: add an empty adr_link

2026-04-26T21:54:56+00:00

An empty adr_link is expected to terminate the
for (adr_link = mach_params->links; adr_link->num_adr; adr_link++) loop.
Allocate link_num + 1 links to add an empty adr_link.

ASoC: SOF: Don't allow pointer operations on unconfigured streams

2026-04-10T12:57:09+00:00

When reporting the pointer for a compressed stream we report the current
I/O frame position by dividing the position by the number of channels
multiplied by the number of container bytes. These values default to 0 and
are only configured as part of setting the stream parameters so this allows
a divide by zero to be configured. Validate that they are non zero,
returning an error if not

ASoC: SOF: Intel: hda: modify period size constraints for ACE4

2026-04-08T12:15:40+00:00

Intel ACE4 based products set more strict constraints on HDA BDLE start
address and length alignment. Add a constraint to align period size to
128 bytes.

The commit removes the "minimum as per HDA spec" comment. This comment
was misleading as spec actually does allow a 2 byte BDLE length, and
more importantly, period size also directly impacts how the BDLE start
addresses are aligned, so it is not sufficient just to consider allowed
buffer length.

ASoC: SOF: Intel: fix iteration in is_endpoint_present()

2026-04-06T12:23:32+00:00

is_endpoint_present() iterates over sdca_data.num_functions, but checks
the dai_type according to codec info list, which will cause problems if
not all endpoints from the codec info list are present. Make sure the
type of actually present functions is compared against target dai_type.

ASoC: SOF: compress: return the configured codec from get_params

2026-04-06T12:11:57+00:00

The SOF compressed offload path accepts codec parameters in
sof_compr_set_params() and forwards them to firmware as
extended data in the SOF IPC stream params message.

However, sof_compr_get_params() still returns success without
filling the snd_codec structure. Since the compress core allocates
that structure zeroed and copies it back to userspace on success,
SNDRV_COMPRESS_GET_PARAMS returns an all-zero codec description
even after the stream has been configured successfully.

The stale TODO in this callback conflates get_params() with capability
discovery. Supported codec enumeration belongs in get_caps() and
get_codec_caps(). get_params() should report the current codec settings.

Cache the codec accepted by sof_compr_set_params() in the per-stream SOF
compress state and return it from sof_compr_get_params().
