The (RAS Error-record Register Interface) RERI provides a specification to augment RAS features in RISC-V SOC hardware to standardize reporting and logging of errors by means of a memory-mapped register interface to enable error detection, provide the facility to log the detected errors (including their severity, nature, and location), and configuring means to report the error to a handler component.Love Open Source and this site?
