trustedfirmware git and gerrit slowness

by Olivier Deprez

Hi, You must have noticed slowness or breakages with review.trustedfirmware.org or git.trustedfirmware.org during the week. There are high and lows of network bandwidth usage affecting server availability. The issue is being investigated but not yet 100% root caused. Apologies for the frustration and inconvenience that this is causing. Rest assured the team is on board to resolve this unfortunate situation. Regards, Olivier.

Upcoming merge notification for RMM EL0 app support

by Soby Mathew

Hi Everyone As discussed in TF-A Tech Forum in January, RMM is introducing EL0 app support which is deprivileging parts of RMM to run at EL0. This is done mainly for security but it also enables other capabilities as discussed in the presentation : https://github.com/TF-RMM/tf-rmm/wiki/TFA-Tech-Forum-Presentations The patch stack can be accessed here : https://review.trustedfirmware.org/c/TF-RMM/tf-rmm/+/36886/1 . This is complex functionality touching many parts of RMM. The merge is likely to affect outstanding patches as they would have merge conflict on rebase. We have identified further enhancements and hardening which can be done to improve the security and performance of the EL0 app framework . These will be taken up after the merge. We are hoping to merge this patch stack early next week so that any issues identified can be fixed up prior to TF-A v2.13 release planned for next month. The design document is still undergoing review and will be progressed after the merge of functionality. Best Regards Soby Mathew

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
