by Olivier Deprez

Hi, In light of coming TF-A v2.14 in November, we would like to mark the SPM-MM implementation [1] as deprecated. Our understanding is that it's not longer very actively used at least from an upstream perspective, while most SPM sw architecures have adopted/migrated to the FF-A standard [2] [3]. The intent would be to remove this implementation completely from next release in May 26 onwards. This would remove the maintenance burden for 3 orthogonal options, reducing to the 2 FF-A compliant implementations. Simplification also comes to the testing side and CI. The SPM-MM implementation would continue to be supported in LTS branches maintained for 7 years. Let us know if this causes major concerns. Thanks, Regards, Olivier.

Firmware-A v2.13 release code freeze notification

by Olivier Deprez

Hi All, The next release of the Firmware-A bundle of projects tagged v2.13 has an expected code freeze date of May, 2nd 2025. In order to accommodate the Linaro connect event occurring during the week of May 12th we may extend the release completion date up until the week of May 26th. v2.13 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. Regards, Olivier.

Rethrow SEA from EL3 to lower EL on arm64

by Venkata Pokkuluri

In Firmware First Handling (FFH), all external aborts are trapped to EL3, they can be notified to OS/VM using SDEI or by reinjecting SEA. SDEI is imprecise exception and asynchronous. GHES driver defines SEA as the only synchronous mechanism ( https://github.com/torvalds/linux/blob/master/drivers/acpi/apei/ghes.c#L118), hence SEA reinjection is useful for SEA's where OS/VM takes appropriate action. For example when an user space application running at EL0 consumes a poisoned memory by re-throwing SEA the kernel can terminate the individual application. For SEA Reinjection we need to figure out the right EL to reinject the SEA to and then copy ESR_EL3, SPSR_EL3, ELR_EL3 and FAR_EL3 to target ELs respective registers and calculate new PSTATE for EL3. To find target_el reference code is provided in SyncExternalAbortTarget (J1.3.2.7) in ARM DDI 0487L.a.
