Re: [TF-A] Unhandled Exception at EL3 in BL31 for Neoverse N1 with direct connect of DSU

by Manish Badarkhe

Hi Andrzej I think recent patch: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3493 which is currently in review may be solution for your issue where SCU presence is being checked before accessing CLUSTERCFR_EL1 register.

The root cause is that after invoking neoverse_n1_errata-report function in lib/cpus/aarch64/neoverse_n1.S file and reaching the line 525, the function check_errata_dsu_934 in lib/cpus/aarch64/dsu_helpers.S file is always invoked regardless of whether ERRATA_DSU_936184 is set to 0 or to 1.

Announcing new maintainers for the TF-A project

by Sandrine Bailleux

Hi all, Now that the tf.org project maintenance process [1] has been finalized, it is time to think about electing new maintainers for the project. We are delighted to announce that the following contributors have been appointed maintainers by their peers: - Julius Werner (Google) - Varun Wadekar (NVIDIA) - Andre Przywara (Arm) - Lauren Wehrmeister (Arm) - Madhukar Pappireddy (Arm) As outlined in [1], here is the definition and responsibilities of maintainers: ------------8<------------ There are a number of maintainers assigned to the project. The project keeps a list of them along with their contact information. Maintainers don't necessarily need a deep domain expertise of all areas of the project, instead they look at the project from a high level perspective. They are expected to ensure that changes adhere to the project's quality criteria, to its architectural direction, to its threat model and so on. Code owners and maintainers are complementary roles. Unlike code owners, maintainers can approve any patch, no matter what module it concerns. They are responsible for ensuring patches have had enough overall review and adding their own approval in a timely manner. They also have merge rights, i.e. the ability to merge a patch in the tree once it has received all required approvals. ------------8<------------ These people have been granted Code-Review -2/+2 rights in Gerrit and have been added in the maintainers.rst file as part of this patch: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/4298 Congratulations to them! Best regards, Sandrine [1] https://developer.trustedfirmware.org/w/collaboration/project-maintenance-p…
