Hi All,
In preparation to the Firmware-A v2.12 bundle release the following TF-A/TF-A-tests/Hafnium/RMM/CI project tags were applied:
https://git.trustedfirmware.org/TF-A/trusted-firmware-a/+/refs/tags/v2.12-r…https://git.trustedfirmware.org/tf-a-tests/+/refs/tags/v2.12-rc0https://git.trustedfirmware.org/ci/tf-a-ci-scripts/+/refs/tags/v2.12-rc0https://git.trustedfirmware.org/ci/tf-a-job-configs/+/refs/tags/v2.12-rc0https://git.trustedfirmware.org/hafnium/hafnium.git/+/refs/tags/v2.12-rc0https://git.trustedfirmware.org/ci/hafnium-ci-scripts.git/+/refs/tags/v2.12…https://git.trustedfirmware.org/ci/hafnium-job-configs.git/+/refs/tags/v2.1…https://git.trustedfirmware.org/TF-RMM/tf-rmm/+/refs/tags/tf-rmm-v0.6.0-rc0
Trees are frozen still accepting security or bug fixes until the release close down happening end next week (hopefully!).
For partners, it will help if tests are run against those trees on downstream platforms and spot any issue hit before the final tagging.

Subject: [Tf-a-tests] Firmware-A v2.12 release code freeze notification
Hi All,
The next release of the Firmware-A bundle of projects tagged v2.12 has an expected code freeze date of Nov, 8th 2024.
Refer to the release cadence section from TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…).
Closing out the release takes around 6-10 working days after the code freeze.
v2.12 release preparation tasks start from now.
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 labels 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.

Subject: [Tf-openci] CI infrastructure scheduled maintenance: 12th Sep 2025
Hi all,
We will be performing upgrade of the clusters hosting review.trustedfirmware.org and ci.trustedfirmware.org on Friday, 12th Sep 2025 at 16:00 GMT+1.
During this maintenance window, both services will be unavailable for approximately 4 hours.
A follow-up email will be sent once the services are fully restored.
Best regards,
Saheer

Hi Everyone,
The FEAT_MEC enablement patches have now been merged into RMM:
https://github.com/TF-RMM/tf-rmm/commit/8819a19d048b273438690954c151c8333db…
This marks the culmination of several months of work.
The patch series went through two major rewrites as we experimented with different implementation approaches. This also led to a re-design of the delegate scrub flow in RMM, which was merged earlier as a precursor to this work.
We also received design inputs from @Raghu K , which resulted in more fine-grained programming of the MEC registers. In addition, two extra hardening methods were implemented based on this feedback. These can be enabled via the RMM_MEM_SCRUB_METHOD build flag.
In the coming days, we plan to profile the three different scrub methods to determine a more suitable default.
The FEAT_MEC design in RMM and rationale for the hardening is explained here:
https://github.com/TF-RMM/tf-rmm/wiki/RFC:-FEAT_MEC-Design-in-RMM
As usual, please let us know if you find any issues.
Best Regards
Soby Mathew
Hi Everyone,
The Planes patch stack has been merged!
https://github.com/TF-RMM/tf-rmm/commit/d2f72c4ec9e091b8bb12b53fe2bc022351f… .
This update includes more than 15K lines of code changes. Some patches went through 100+ revisions over the last 1.5 year, and we've added significant new framework support as well as test cases to TFTF. As with any large integration, we expect to encounter some issues in the coming days, which we'll be addressing . We already have a list of improvements and fixups identified, and more TFTF tests will follow.
In the meantime, please let us know if you come across any issues or have suggestions for improvements.
Best Regards
Soby Mathew
Hi Everyone,
I'm pleased to announce that Raghupathy K has joined the group of maintainers for TF-RMM. This decision reflects Raghu's significant contributions to the project, including code reviews, design discussions and feature contributions over the past couple of years.
The maintainers file has been updated accordingly : https://github.com/TF-RMM/tf-rmm/blob/main/docs/about/maintainers.rst
Best regards,
Soby Mathew (on behalf of all TF-RMM maintainers)
Hi Everyone,
We merged the new ID sysreg management scheme into RMM today.
Background:
Previously, RMM directly read the ID_xxx sysregs to determine hardware capabilities before enabling features in the Realm world. This approach implicitly required EL3 to enable the feature first, creating a revision lockstep between RMM and the EL3 firmware.
New Scheme:
With the updated ID register management, EL3 capabilities are queried via the SMCCC_ARCH_FEATURE_AVAILABILITY call. RMM now maintains a shadow copy of the ID sysregs in memory (referred to in the codebase as the cached_ID reg). This cached copy is populated during cold boot, and RMM will only access the cached ID regs at runtime.
The design also anticipates future support for FEAT_IDTE3 in TF-A.
Benefits:
* Sanitized Realm view of ID regs: Instead of using a "disallow" mask, RMM now uses an "allow" mask to define what features are exposed.,
* Forward compatibility: Older RMM versions running on newer architectures will not expose previously RES0 fields to realms, thanks to the "allow" mask approach.,
* Feature discrepancy handling: In the future, RMM could detect CPU feature differences and react accordingly.,
* Live migration readiness: This scheme may also help when handling feature differences in live migration scenarios.,
The merge commit can be found here : https://github.com/TF-RMM/tf-rmm/commit/4a9d781892074e8997e73411cfe5a220223…
The current CI tests are passing. There is a chance that we may not have exposed all the bitfields needed, but if you find any failure due to missing ID features, please let us know.
Please be aware that outstanding patches may need to be rebased on top of this.
Best Regards
Soby Mathew
