Re: [TF-M] Use IPC Model to build by default

Hi all,

The patches have been merged. Please be noted again:

* IPC model is now built by default * Keeping the -DTFM_PSA_API=ON is still OK in your CI or build scripts, but it’s recommended to remove it. * To build library model, please use -DTFM_LIB_MODEL=TRUE

Best Regards, Kevin

Hi all,

The patch in CI for this change is ready as well. https://review.trustedfirmware.org/q/topic:%22ipc_model_by_default%22+(statu...)

We’d like to merge them in this week, if there were no objections.

With this patch, if you build IPC model the commands do not need to change. But it is recommended to remove the -DTFM_PSA_API=ON. If you build library model, you need to add -DTFM_LIB_MODEL=TRUE.

Best Regards, Kevin

Hi all,

Please be noted that we are changing the build system to build IPC model by default instead of Library model for the following reasons:

* The Library Model is not being developed anymore. It does not support for new FF-M features. * New comers to TF-M should be encouraged to start with the IPC model to have the better experiences. * Most importantly, Library Model will be replaced by SFN Model in future.

Patch here: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/11384

With this patch, the TFM_PSA_API is not intended for users to choose between library and IPC model anymore. To build Library model, please set TFM_LIB_MODEL to ON. The TFM_PSA_API=ON can be kept as is for the time being.

So there would be impacts wherever Library Model is used. Please get prepared.

Thanks.

Best Regards, Kevin
