Linux Security Summit Europe 2024

This session aims to cover ISA and non-ISA for Confidential VM Environment (CoVE) on RISC-V platforms. The session will describe the use of ratified RISC-V privileged ISA extensions and new priv. ISA extensions called "Supervisor Domains" that are proposed and reaching task group consensus. This session will also describe the specifications for proposed non-ISA/ABI extensions and SoC requirements that enable Confidential Computing on RISC-V-based platforms - and the related open-source activities in open-source that are required to enable the confidential computing stack on RISC-V platforms. The common/abstract aspects that are cross-architectural will be discussed to enable interoperability across different RISC-V and non-RISC-V platforms. A future roadmap of capabilities will be discussed to encourage participation from the community.
