Hi folks,
If you don’t use any of the JavaScript-based tooling from the TF-A repository then you can safely ignore this.
I’ve just updated TF-A’s Node.js dependencies, including the minimum version of Node.js required to use the JavaScript-based hooks and tooling from the repository (previously v16, now v20). If you use these and you find that they have started throwing errors, make sure that you are rebased on the latest version of the integration branch, and then run:
npm ci
If you need to commit changes while the tools are erroring, you can commit with the `-n` flag to skip the commit hooks:
git commit -n <usual commit flags…>
Please let me know if you run into any issues.
Cheers,
Chris
Hi Olivier Deprez,
One more question, the SPM_MM code will not be removed from the main repository, right?
________________________________
Hi Olivier Deprez,
We use the SPM_MM framework mainly for read/write control of security variables. We do not want to modify the original application code at this time.
At the same time we want to add support for the new SPMD framework based code.
________________________________
Hi Baopeng,
By "code based on the SPM_MM framework" I assume you refer to a secure service running in a S-EL0 partition based on the MM protocol? If you can share this information, what kind of service is this implementing? RAS handling, secure variables, TPM back end, other? What kind of interface is needed to access the service? asynchronous with interrupts? synchronous with SMC from normal world? Another question is why do you need to collocate the SPMD if the MM implementation is already achieving the scenarios you need?
Ideally you'd want to migrate this service to run on top of:
* the EL3 FF-A SPMC https://trustedfirmware-a.readthedocs.io/en/latest/components/el3-spmc.html * or if the HW/chipset implements it, the S-EL2 FF-A SPMC https://hafnium.readthedocs.io/en/latest/secure-partition-manager/index.html...<https://hafnium.readthedocs.io/en/latest/secure-partition-manager/index.htm…>
Knowing the kind of S-EL0 service would help narrowing the effort for a migration.
FF-A (https://developer.arm.com/documentation/den0077/latest/) is a modern evolution of MM (https://developer.arm.com/documentation/den0060/latest) and any functionality achieved by the MM protocol can be handled by FF-A. For example the MM_COMMUNICATE interface can be easily swapped by the FFA_MSG_SEND_DIRECT_REQ interface.
Regards, Olivier.

Hi Baopeng,
SPM_MM is the legacy implementation for a secure partition manager relying on the MM protocol. This implementation gets deprecated in favor of FF-A based implementations (what you refer to as SPMD + SPMC). Both implementations aren't compatible and it is discouraged to attempt co-locating both. It may be more palatable and future proof to transition all your SW stack to be compliant to FF-A standard.
We may help you better if you tell a bit more about the reason for mixing both implementations in the same build.
Regards, Olivier.

Dear Sir/ Madam,
we need to support the simultaneous loading of SPMD and SPM_MM due to project reasons.
However, we notice that the makefile of SPM_MM of ATF does not support the simultaneous loading of SPMD and SPM_MM by default.
I would like to ask what is the main reason for making the current restrictions?

Hi Olivier Deprez,
We have developed code based on the SPM_MM framework and do not want to reconstruct the code. However, we want to adapt the code to the SPMD framework.
What should we do?
________________________________
Hi Baopeng,
SPM_MM is the legacy implementation for a secure partition manager relying on the MM protocol. This implementation gets deprecated in favor of FF-A based implementations (what you refer to as SPMD + SPMC). Both implementations aren't compatible and it is discouraged to attempt co-locating both. It may be more palatable and future proof to transition all your SW stack to be compliant to FF-A standard.
We may help you better if you tell a bit more about the reason for mixing both implementations in the same build.
Regards, Olivier.

Hello,
I'm trying to understand the purpose of ENABLE_PIE build flag.
IIUC, it makes the BL* executables position-independent. But I could not find
any ASLR or some other addresses randomization support. Therefore, could you
please clarify, what is the point of building position-independent parts,
if (most of the time?) they will be loaded at the fixed addresses?
Thank you.
