This change encounters following errors when we run on MTL platform machine:

[   51.125310] <err> llext: do_llext_load: Failed to allocate extension symbol table, ret -12
[   51.125340] <err> lib_manager: llext_manager_link_single: linking failed: -12
[   51.125346] <err> lib_manager: lib_manager_module_create: lib_manager_allocate_module() failed!
[   51.125378] <err> ipc: ipc4_init_module_instance: error: failed to init module 1000 : 0
[   51.125385] <err> ipc: ipc_cmd: ipc4: MODULE_MSG failed with err 104

Seems like symbol table size has some limitation.

See
mtrace.log
for full logs.

See
build.log
for build info.

dax_dev_overlay.conf is:

CONFIG_COMP_MODULE_ADAPTER=y
CONFIG_COMP_DOLBY_DAX_AUDIO_PROCESSING=m
CONFIG_COMP_DOLBY_DAX_AUDIO_PROCESSING_MOCK=n
CONFIG_KCPS_DYNAMIC_CLOCK_CONTROL=n

I have no idea what the limitation is.

test this please

LGTM, I'm good to go ahead whilst we work on optimizing linking speed for larger modules

[kv2019i]

The issue with "CONFIG_LLEXT_EXPERIMENTAL" warrants follow-up, but I don't think blocking this PR (given this is feature overlay specific to one platform).

I recommend adding inline comments to dax_overlay.conf for the less-than-obvious settings.

@kv2019i I have added comment and create a new issue: #10370

The CI check failure does not appear to be caused by this change. The code that casue code style check failure is totally copied from src/audio/tensorflow/llext-wrap.c, is this failure allowed?

Yes, the code style checker is too picky sometimes. Its advisory.
