Hi Everyone, The RMM v2.0 Beta 0 specification has been published here: https://developer.arm.com/documentation/den0137/latest/ As you may have noticed, this release introduces breaking changes to the RMI APIs (host side), while the RSIs (guest side) remain backward compatible. Nearly all ABIs are affected, and the scope of these changes makes it highly disruptive to maintain support for both RMI v1.x and RMI v2.0 within the same codebase. We do not expect RMI v1.x to be deployed in production, and retaining support for it would increase development overhead and the risk of introducing bugs. A more pragmatic approach is to branch the current RMM codebase at the RMI v1.x ABI and then migrate the mainline to the RMI v2.0 ABI. This will be a breaking change for host-side components that rely on the older RMI ABI. Given the extent of the ABI changes, significant effort will be required to align with RMI v2.0, and this approach allows the team to focus on upstreaming the new ABI support efficiently. The initial RMI v2.0 upstreaming will consist of a series of commits that together form an initial RMM implementation targeting the RMM v2.0 specification. This initial implementation will not be fully feature-complete with respect to the v2.0 spec, and we expect to continue layering additional RMM v2.0 ABI-related changes on top as the implementation matures during the course of the year. That said, we intend to maintain integration with an externally available, compatible Linux host kernel branch throughout this process. The initial RMI v2.0 RMM implementation will be compatible with an initial v2.0-based host kernel, and we will notify the mailing list once this integration is available to pick up (likely end of March '26). If and when we need to introduce further ABI changes that break compatibility with a previously published kernel branch, we will call this out explicitly in advance and indicate when an updated kernel branch will be available for integration. We plan to keep RMI v1.x ABI as a separate branch and selectively merge bug fixes on a request or need basis. Please let us know if you have any concerns regarding this plan within the next two weeks. Best Regards Soby Mathew

Realm guest stuck in IRQ loop

by Manoj Ekbote

Hello, We are observing a recurring virtual‑timer IRQ loop during Realm guest bring‑up under TF‑RMM with RME enabled. The problem seems to be an ordering issue around restoring Realm timer state at EL2 and subsequently evaluating pending timer conditions. When a virtual-timer interrupt is taken to EL2-R, the timer registers (CNTV_CTL=0x5 and CNTV_CVAL) are saved, and the IRQ is then reported to host OS. When EL2 restores CNTV_CTL and CNTV_CVAL on return from the host, the write sequence is not synchronized before EL2 performs the timer‑pending check in the function check_pending_timers(). Because CNTVCT continues to advance, and CNTV_CVAL < CNTVCT is already true at restore time, the read of CNTV_CTL can reflect a stale value (0x1). As a result, EL2 does not set CNTHCTL_EL2.CNTVMASK, fails to clear the pending virtual‑timer interrupt, and the IRQ is re‑asserted immediately upon Realm re‑entry—causing the repeated exit/entry loop. Inserting an isb() after restoring the Realm’s timer registers and before performing the timer‑pending check helped resolve the issue. I’d appreciate any feedback. Thanks

TF-A Tech Forum Dec 11th 4.00pm (UK) - TF-RMM Live Firmware Activation (design update)

by Olivier Deprez

Hi, On Dec 11th in the TF-A Tech Forum at 4.00pm UK, Soby Mathew will present a design update on TF-RMM Live Firmware Activation: This presentation describes the revised TF-RMM Low-VA MMU and global-runtime-data design required to support Live Firmware Activation (LFA). Compared to the earlier approach (outlined in the TFA Tech Forum session on 12-Jun-2025 [1] ), which assumed mostly fixed boot time mappings and per-platform handcrafted Low-VA contexts, the new design is driven by several changes in RMM specification: RMM must now support runtime mapping/unmapping of PAs for RMM objects like struct granule , reuse those dynamic mappings across LFA transitions. These PAs can come either from NS world at runtime or EL3 reservation from RMM carveout. In order to migrate Stage 1 dynamic mappings across LFA instances, RMM needs to reduce dependence on platform-specific MMU setup, and provide a structured framework for allocating, versioning and migrating global runtime data. The Stage 1 Low-VA is therefore split into static and dynamic regions managed by the common xlat layer. The detailed design is captured in the TF-RMM wiki RFC “TF-RMM Live Firmware Activation [2]” and builds on the initial design presented in the TFA Tech Forum session on 12-Jun-2025 [1] : [1] Previous LFA discussion: https://github.com/TF-RMM/tf-rmm/wiki/TFA-Tech-Forum-Presentations [2] https://github.com/TF-RMM/tf-rmm/wiki/RFC:-TF%E2%80%90RMM-Live-Firmware-Act… Regards, Olivier.

Firmware-A v2.12 release rc0 tag

by Govindraj Raja

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-rc0 https://git.trustedfirmware.org/ci/tf-a-ci-scripts/+/refs/tags/v2.12-rc0 https://git.trustedfirmware.org/ci/tf-a-job-configs/+/refs/tags/v2.12-rc0 https://git.trustedfirmware.org/hafnium/hafnium.git/+/refs/tags/v2.12-rc0 https://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. -- Thanks, Govindraj R ________________________________ From: Govindraj Raja via TF-A-Tests <tf-a-tests(a)lists.trustedfirmware.org> Sent: Monday, October 14, 2024 20:18 To: Joanna Farley via TF-A <tf-a(a)lists.trustedfirmware.org>; tf-a-tests(a)lists.trustedfirmware.org <tf-a-tests(a)lists.trustedfirmware.org> Cc: hafnium(a)lists.trustedfirmware.org <hafnium(a)lists.trustedfirmware.org>; tf-rmm(a)lists.trustedfirmware.org <tf-rmm(a)lists.trustedfirmware.org>; trusted-services(a)lists.trustedfirmware.org <trusted-services(a)lists.trustedfirmware.org> 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. -- Thanks, Govindraj R -- TF-A-Tests mailing list -- tf-a-tests(a)lists.trustedfirmware.org To unsubscribe send an email to tf-a-tests-leave(a)lists.trustedfirmware.org

TF-A Tech Forum on Thu Oct 30th 2025 4.00pm UK

by Soby Mathew

Hi, Sona Rebecca Mathew will present on the TF-RMM ID registers management scheme at the TF-A Tech Forum tomorrow. Her presentation is expected to take place during the second half of the one-hour session. Abstract: * Earlier RMM directly read ID registers, creating a dependency on EL3 revisions to enable features forcing a version compatibility between the two. * New approach: EL3 capabilities are queried via an SMC call and RMM now uses cached ID register copies populated at cold boot. Includes forward-looking support for FEAT_IDTE3 in TF-A. For meeting details, please refer to the TF-A Tech Forum email here : https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… Best Regards Soby Mathew

DA Alp-12 based patch stack merged

by Soby Mathew

Hi Everyone, We've merged the final batch of outstanding patches for Alp-12-based DA foundation support in RMM: TF-RMM Commit bd2eb59<https://github.com/TF-RMM/tf-rmm/commit/bd2eb596ca0739c8051badefde34993e24f…> This completes the fourth and final merge in the series, incorporating support for DVSEC and IDE key programming. With this, the refactoring of the Alp-12 branch to the EL0 app framework is now complete. (Some quick stats: over 60 patches and >13K lines of code changed.) While the current base support has several limitations that we plan to address in the coming months including: 1. Initial SMMU Stage 2 driver 2. Updated IDE key programming flow 3. Alp-16 migration groundwork 4. Multi PDEV/VDEV support 5. Validation of PDEV , VDEV params and improved testing from TFTF. With the base DA support now in place, RMM is ready to accept contributions to further improve Device assignment support. Best Regards Soby Mathew
