This talk explores the EL0 app framework within TF-RMM (Trusted Firmware Realm Management Monitor), which enables deprivileging parts of RMM to run in a separate address space at EL0. Learn about this firmware component that operates at Realm EL2 and forms part of the Arm Confidential Compute Architecture (Arm CCA) implementation. Discover how the framework introduces capabilities for per CPU or vCPU(REC) thread instances associated with the EL0 app. The 26-minute presentation covers both the rationale behind this approach and the detailed design of the framework within RMM.
