Speaker
Description
Arm is developing Live Migration ABIs for the Arm Confidential Compute Architecture (CCA), with input and requirements from ecosystem partners. The ABIs are provided by the Realm Management Monitor (RMM), the trusted firmware component responsible for managing Realms.
The presentation will start with a short overview of the high-level CCA Live Migration design and the end-to-end process. It will then examine the assumptions and design choices underpinning the ABIs in three areas: core design, platform preconditions, and runtime mechanisms, relating each to the broader security, correctness, and practicality constraints of confidential live migration.
Finally, the presentation will provide a basis for discussing how the emerging CCA Live Migration ABIs and Linux/KVM infrastructure for confidential-computing migration can inform one another.
