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

Re: Question about SPM-MM SMC function ids

When SPM-MM is enabled, I cannot use the TRNG SMC services. /* These macros are used to identify SPM-MM calls using the SMC function ID */ #define SPM_MM_FID_MASK U(0xffff) #define SPM_MM_FID_MIN_VALUE U(0x40) #define SPM_MM_FID_MAX_VALUE U(0x7f) #define is_spm_mm_fid(_fid) \ ((((_fid) & SPM_MM_FID_MASK) >= SPM_MM_FID_MIN_VALUE) && \ (((_fid) & SPM_MM_FID_MASK) <= SPM_MM_FID_MAX_VALUE)) Here, the SPM-MM SMC ID range spans from 0x40 to 0x7F, which overlaps with the TRNG SMC service IDs: /* SMC function IDs for TRNG queries */ #define ARM_TRNG_VERSION U(0x84000050) #define ARM_TRNG_FEATURES U(0x84000051) #define ARM_TRNG_GET_UUID U(0x84000052) #define ARM_TRNG_RND32 U(0x84000053) #define ARM_TRNG_RND64 U(0xC4000053) Could you please clarify the rationale behind including the TRNG SMC IDs within the SPM-MM ID range? 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.
