Some questions

How are we testing this today ? and how should we test in CI
Does this version support the dynamic linking or just the dynamic loading today ?

dbaluta · 2022-05-11T14:34:09Z

@pjdobrowolski @lgirdwood aside from having this quick merged what stops us from implementing this feature in zephyr?

marc-hb · 2022-05-11T17:14:45Z

Most checkpatch warnings at https://sof-ci.01.org/sofpr/PR5796/build327/checkpatch/ seem valid (and easy to fix)

This PR is only small part responsible for loading library binary. More changes are required to have something testable.

Does this version support the dynamic linking or just the dynamic loading today ?

We support now dynamic loading of library containing 3rd party module binary. Currently available libraries in IADK (Windows close source FW) are not supporting dynamic linking, however it could be supported in the future.

Maybe that's why it's still a draft?

@jxstelter fyi since @pjdobrowolski is out.

@pjdobrowolski, do you have any library I can try to load with my Linux side PR (thesofproject/linux#3826)?

pjdobrowolski · 2022-08-29T12:02:30Z

@pjdobrowolski, do you have any library I can try to load with my Linux side PR (thesofproject/linux#3826)?

You can build one yourself using https://github.com/thesofproject/converged-sof-modules

FYI: I came back from 2 week long sick leave and you guys flooded me with changes which should be requested almost 2 months ago. @dbaluta @ujfalusi @lgirdwood @lyakh I understand that next few days I will spend on resolving that requests. And I thought that sinusitis was bad...

@pjdobrowolski don't worry you will get used with us ;). glad that you are better now.

In order to get your patches faster accepted open source community has some guidelines:

split your patches into simple logical units.
make your code clean. follow naming conventions. Run ./scripts/checkpatch.pl over your patch.
avoid having more then 3-4 level of indentation in the code.
when introducing new features in a series: please add the bugfixes first and the patches introducing new code later.

I will be on vacation until next week so you I'm off your back for a while :). But I'll be back.

@dbaluta Are there any guidelines like that for reviewers or just "hit and run"?

lgirdwood · 2022-08-30T08:23:25Z

@pjdobrowolski can you force push again, I've just merged the build fix for IPC4 and newer CC. Thanks

your .lib_notif_pool is somewhat... unusual. Usually you'd just have a list head in the higher level object (in ext_lib in this case) to which you then link elements as you allocate them. Instead you have a pointer to lib_notif_pool there and once you allocate the first element and attach it there, you then link further allocated elements to the first one. That makes the list head instance in that object both - a list head and a list element. list_empty() now means not 0 elements, but 1... All that can be made to work of course but just is a bit unusual and one has to remember about this when working with this code.

So what would you suggest. That might be refactored for sure but I think that main goal is to port that feature from legacy and integrate. Many mechanisms used here are borrowed from older firmware and for sure they can be improved. We can do that later if it isn't so wrong.

@lrudyX @wszypelt can you check CI, not expecting this to fail where it did. Looks like a copy issue ? Thanks.

@lgirdwood yea...
TGL was disabled, I fixed it and ran the tests again.

Library manager is part of loading external libraries responsible of handling data and placing it in proper order and places. This feature is using module adapter API for loadable native and external libraries.

…red. System service functionality used by 3rd party modules expects that IPC data buffer will be filled with data during notification preparation. To avoid additional data copy, provide message buffer directly to module. This requires that ipc_msg_send() function will not fail if source data pointer will be equal to destination one.

+ msg = ipc_msg_init(header, SRAM_OUTBOX_SIZE);
+ if (!msg)
+ rfree(msg_pool_elem);
+ return NULL;


You need braces here

So reopen PR and will fix it.
