Hi,

In IPC4 all DSP loadable executable is a 'library' containing modules. The main
or basefw is also a library which contains multiple modules.
IPC4 allows to use loadable libraries to extend the functionality of the booted
basefw.

This series adds support for loading external libraries in case they are needed
by the loaded topology file.

The libraries must be placed to a specific firmware directory (fw_lib_prefix),
which is:
intel/avs-lib|sof-ipc4-lib/ followed by the platform name and in case of
community key use a 'community' directory.

For example for upx-i11 (community key): intel/avs-lib/tgl/community is the
default path.

The name of the library should be the UUID of the module it contains since the
library loading is going to look for the file as <module_UUID>.bin
In case there is a need to bundle multiple modules into single library, symlinks
can be used to point to the file:

module_boundle.bin
<UUID1>.bin -> module_boundle.bin
<UUID2>.bin -> module_boundle.bin
<UUID3>.bin -> module_boundle.bin

But note that in this case all modules will be loaded to the DSP since only the
whole library can be loaded, not individual modules.

Regards,
Peter

I'm not sure that I understand the rationale here, can't libraries be 
kept in the same directory as FW, as far as I know they are version 
locked to FW anyway. In avs driver when we decided on intel/avs/platform 
path we planned to keep FW related libaries there...

During the internal review we arrived to this setup, to keep the
libraries separate from the basefw binary.
One of the reason is that SOF project is not likely not going to release
external libraries, they are mostly vendor/product locked.
To make the life easier for the vendors (and distributions, packagers)
we concluded that it is better to keep them separate.

The option is there to specify custom path as well in case it is needed.

My initial approach was this as well, but after a long debate it got
revised.

That's a common LOTR reference :-)


I'll address the rest of the feedback tomorrow. Thanks for the input though!

No problem, leaving this out of the discussion.

In majority of cases since Broadwell, that's the reality though. While 
theory may say otherwise, we were (and still are) releasing 
generation-wide builds e.g.: SKL-based firmware package, TGL-based 
firmware package.

Thanks for the elaborate input. The evolution sound good, and is 
perfectly reasonable. My only feedback is - should we put everything 
under /intel directory? If all the paths can be customized, then the 
parent directory needs not to be the same for every firmware package 
regardless of its origin. It's counterintuitive, is it not?

The concern is understandable. We haven't said that firmware files 
should be put directly under intel/ though.

Neither 'dsp_fw_' nor 'dsp_lib_' prefix is arbitrary. A library may 
consist of more than one module, each with unique UUID. In general, 
'library' does not equal 'module'. Now, when speaking of modules, 
firmware-loading procedure that searches for file with certain UUID in 
its name is part of other drivers too and I haven't questioned that - 
it's perfectly fine and we're making use of the method ourselves.
