Firmware-A v2.10 release code freeze notification

by Olivier Deprez

Hi All, The next release of the Firmware-A bundle of projects tagged v2.10 has an expected code freeze date of Nov, 7th 2023. Refer to the Release Cadence section from TF-A documentation (https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/docs/about…). Closing out the release takes around 6-10 working days after the code freeze. Preparations tasks for v2.10 release should start in coming month. 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 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 & Regards, Olivier.

Re: [TF-A] Console scope flags/ console switch state - understanding

by Belsare, Akshay

Hi, Since the discussion is already going on in TF-A list extending it to TF-A Tests list as well. Does TF-A Tests have test cases for console testing in TF-A? more specifically to test the CRASH console?
