About

After RISC-V RERI specification was defined, as a follow up we also would like to complement it with required system software specifications to enable end to end RAS error handling flows.

Project Scope and Timelines

• Implement Qemu module to support RERI defined registers and RAS interrupt functionality

• Implement edk2 RAS drivers to fetch and prepare HEST ACPI tables

• Implement RAS agent within OpenSBI to service RAS errors and communicating with external RAS controller

• Additional: MM mode implementation will be covered as part of a separate project
