[tf-rmm] TF-A Tech Forum on Thu Oct 30th 2025 4.00pm UK

Hi,

Sona Rebecca Mathew will present on the TF-RMM ID registers management scheme at the TF-A Tech Forum tomorrow. Her presentation is expected to take place during the second half of the one-hour session.

Abstract:

* 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.

Best Regards Soby Mathew
