Hi All,
The next release of the Firmware-A bundle of projects tagged v2.10 has an expected code freeze date of Nov, 7th 2023.
Refer to the Release Cadence section from TF-A documentation (https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/docs/about…).
Closing out the release takes around 6-10 working days after the code freeze.
Preparations tasks for v2.10 release should start in coming month.
We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.:
-For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run).
-For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 in the middle of the patch stack).
-Carefully analyze results and fix the change if required, before launching new jobs on the same change.
-If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued.
Thanks & Regards,
Olivier.
Hi all,
I'm testing FF-A notifications with OP-TEE and Hafnium. I'm using
interrupts from the secure uart as a trigger to set a notification for
the normal world. Sometimes when testing I run into:
VERBOSE: Secure virtual interrupt not yet serviced by SP 8001.
FFA_MSG_SEND_DIRECT_RESP interrupted
Hafnium then returns an FFA_ERROR (code -5) as a response to the
FFA_MSG_SEND_DIRECT_RESP OP-TEE was just exiting with. After some
digging in the code I find a comment at the top of
plat_ffa_is_direct_response_interrupted()
https://git.trustedfirmware.org/hafnium/hafnium.git/tree/src/arch/aarch64/p…
/*
* A secure interrupt might trigger while the target SP is currently
* running to send a direct response. SPMC would then inject virtual
* interrupt to vCPU of target SP and resume it.
* However, it is possible that the S-EL1 SP could have its interrupts
* masked and hence might not handle the virtual interrupt before
* sending direct response message. In such a scenario, SPMC must
* return an error with code FFA_INTERRUPTED to inform the S-EL1 SP of
* a pending interrupt and allow it to be handled before sending the
* direct response.
*/
The specification doesn't mention this as a valid error code for
FFA_MSG_SEND_DIRECT_RESP. Is this something we can expect to be added
to the specification or at least something OP-TEE has to be prepared
to handle regardless?
As far as I can tell there's no way of guaranteeing that Hafnium will
not return this error for FFA_MSG_SEND_DIRECT_RESP. Even if we were
able to execute the smc instruction with secure interrupts unmasked,
what if the interrupt is raised just after the smc instruction has
been trapped in Hafnium?
It is a bit inconvenient as it means saving the registers passed to
the smc instruction to be able to restart the smc instruction with the
same arguments. It seems we may need to redesign the exit procedure.
It would be nice with an example of how an S-EL1 SP is supposed to
exit with FFA_MSG_SEND_DIRECT_RESP.
Thoughts?
Thanks,
Jens

Hi,
As of today, the way to build Hafnium is a single make command to build Hafnium binaries (e.g. SPMC) and tests for all platforms at once.
This is an overhead for deployments or integrations downstream that are only interested in building a single platform SPMC image, and are not interested in running Hafnium tests.
We have a proposal to help scaling to those deployments where only an SPMC binary for a given platform is required. On the benefits side, this greatly decreases the build time for said deployments and limits build dependencies (e.g. ones within the test framework).
There are certainly more complex solutions that we thought about (like segregating individual project git trees beyond 'reference') . However, the proposed change remains simple and keeps the build system backwards compatible with existing deployments.
Essentially this introduces a PLATFORM command line build option for the sake of building the SPMC for one given platform (omitting tests). If required it can be combined with the existing PROJECT variable.
Example usages:
* make [PROJECT=reference] : builds all platforms from 'reference' project including tests (same as today)
* make PLATFORM=secure_aem_v8a_fvp_vhe : builds the SPMC targeting FVP from the 'reference' project (omitting tests)
*
Similarly for Arm solutions, make PLATFORM=secure_tc, make PLATFORM=secure_rd_fremont
*
make PROJECT=project1 : make all platforms from alternate project 'project1'
*
make PROJECT=project2 PLATFORM=platform1 : make a single 'platform1' hafnium binary from project 'project2'
See the changes:
https://review.trustedfirmware.org/c/hafnium/hafnium/+/24822https://review.trustedfirmware.org/c/hafnium/project/reference/+/24821/
Let us know if the approach sounds reasonable.
Regards,
Olivier.
