Technical presentation - 30 minutes (including q&a)
- Friday, 16 May 12:40 - 13:05
- Room: Keynote room | Floriana II
The TF-RMM is a firmware component that runs at Realm EL2 and forms part of a system which implements the Arm Confidential Compute Architecture (Arm CCA). This talk discuses the EL0 app framework which allows to deprivilege parts of RMM to run in a separate address space at EL0. The framework also introduces capability to have per CPU or vCPU(REC) thread instance associated with the EL0 app. The talk will cover the rationale and design of the framework in RMM.
