First Hafnium LTS release

by Madhukar Pappireddy

Hi, We will be making the first Hafnium LTS branch release based of the recent v2.14.0 tag. We would encourage anyone interested in Hafnium LTS support or maintenance to subscribe themselves to this mailing list: https://lists.trustedfirmware.org/mailman3/lists/hafnium-lts.lists.trustedf… <https://lists.trustedfirmware.org/mailman3/lists/hafnium-lts.lists.trustedf…> We also recommend to join the hafnium-lts channel in trustedfirmware discord server for real time updates and getting involved with the LTS maintenance. Thanks, Madhukar

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.

Non volatile boot index for the purpose of firmware update

by Patryk

Hi I'm looking for a suggestion for a reliable place to store a small boot index for PSA Firmware Update. SNVS LPGPRs looked promising, but NXP’s guidance is thin and we don’t keep the battery-backed LP domain alive, so those values won’t survive many power cycles. Are there better options on LS1028A? Would using the user RAM byte in our external I2C RTC make sense? Or perhaps should I store it on eMMC? (we don't use raw NOR/NAND flash). That RTC I mentioned is already accessed in both U-Boot and Linux, so I’m wary of conflicts but can try it if you think it’s viable. Any suggestions would be much appreciated. Best regards Patryk

Question about SError exception routing

by Julius Werner

Hi, I have a sort of generic Arm architecture question that's not directly related to TF-A (other than that TF-A controls some of the registers involved in this decision), but I'm hoping that one of the experts here can still help me out or at least refer me to someone who can. I'm trying to figure out how exception routing for SError aborts works in EL2. Specifically, I have a bootloader (BL33) running in NS-EL2 and I want the "simple" setup that it manages all its own exceptions, the same way that an OS kernel normally manages all exceptions at EL1. I assumed that I could achieve that simply by installing exception handlers, unmasking all exceptions in PSTATE, and leaving all the special trap feature bits in the MSRs at 0 (disabled). This seems to work for synchronous exceptions and external aborts, but not for SErrors. Looking at the architecture reference manual (revision L.b), table D1-14 in section D1.3.6.3 (page D1-6114), I can see that my case is represented by the first line (all special trap bits 0), which shows that SErrors caused by EL0 and EL1 would be routed to EL1 as expected (though even when PSTATE.A is 1 which seems odd?), but SErrors caused by EL2 will get ignored and remain pending (with no regard to PSTATE.A). Instead, the "default" behavior I expect (aborts get routed to the EL that caused them if PSTATE.A is 0) seems to require me to enable SCTLR_EL2.NMEA. But if you're looking at the description of SCTLR_EL2.NMEA, it says that it controls whether PSTATE.A masks SError exceptions at EL2 (and that if it is 0, SError exceptions are not taken at EL2 if PSTATE.A == 1). Doesn't that imply that SError exceptions *are* taken at EL2 if PSTATE.A == 0? What does a control that seems to be about trapping masked aborts from a lower EL have to do with unmasked aborts from my current EL? Basically, I think what I'm asking is: is that table really correct as printed (some behavior we've observed seems to indicate it is), and if so, why? Why do SError exceptions seem to behave differently by default in EL1 and EL2 (in regards to unmasked exceptions taken from the same exception level)? Why does the PSTATE.A bit only seem to apply to EL0 and EL1, not EL2 and EL3, even for exceptions taken from the same level, when this peculiarity seems to not be mentioned anywhere else in the manual? Why do SError exceptions get treated so differently from external aborts in EL2/EL3, when in EL1 they seem to mostly count as the same? Is the current description of the NMEA bit in the SCTLR_EL2 register documentation really accurate, if it also seems to make fundamental changes to cases not really mentioned in that description? Is there any way for EL2 to only handle its own SError exceptions without interfering with EL1's exception handling when FEAT_DoubleFault2 is not implemented (other than flipping HCR_EL2.AMO on every EL2 entry/exit)? And am I the only one who finds this all incredibly inconsistent and confusing? I feel like I'm missing some critical insight in how you were meant to think about this to make it make sense, would appreciate any help in that regard! Thanks, Julius

Firmware-A v2.12 release code freeze notification

by Govindraj Raja

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

If this overlap was unintentional, we have to fix it. Looking forward to your insights and feedback on this matter. Thanks Suresh

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

by Olivier Deprez

(re-sending as it seems this email did not properly reach the ML) Hi, On Oct 30th in the TF-A Tech Forum, two different sessions of 30 minutes each will be presented: TF-A SMC fuzzer improvements - Slava Andrianov * Motivating secure world fuzzing * Fuzzer configuration improvements * Future fuzzing work TF-RMM ID registers management - Sona Rebecca Mathew * 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. Regards, Olivier.
