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: 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: Intel: Fix endpoint index if endpoints are missing

2026-04-06T12:23:31+00:00

In case of missing endpoints, the sequential numbering will cause wrong
mapping. Instead, assign the original DAI index from codec_info_list.

ASoC: SOF: Intel: hda: Place check before dereference

2026-03-31T15:54:50+00:00

The struct hext_stream is dereferenced before it is checked for NULL.
Although it can never be NULL due to a check prior to
hda_dsp_iccmax_stream_hw_params() being called, this change clears any
confusion regarding hext_stream possibly being NULL.

Check hext_stream for NULL and then assign its members.

Detected by Smatch:
sound/soc/sof/intel/hda-stream.c:488 hda_dsp_iccmax_stream_hw_params() warn:
variable dereferenced before check 'hext_stream' (see line 486)

ASoC: SOF: Intel: Add a is_amp flag to fix the wrong name prefix

2026-03-26T16:22:42+00:00

According to the Intel sof design, it will create the name prefix
appended with amp index for the amp codec only, such as:
rt1318-1, rt1318-2, etc...

But the rt1320 is a codec with amp and mic codec functions, it doesn't
have the amp index in its name prefix as above.
And then it will be hard to identify the codec if in multi-rt1320 case.
So we add a flag to force the amp index to be appended.
