Overview

This GUID-named DXE driver implements the Intel RST (Rapid Storage Technology) / VROC (Virtual RAID on CPU) RAID configuration and management stack for the Lenovo HR650X platform. It is a large module (906 functions, 428 named) providing HII-based RAID configuration via UEFI Human Interface Infrastructure, disk/volume management, RAID device enumeration, and RAID migration/recovery services.

The driver manages RAID levels 0/1/5/10/Recovery through the Intel Storage Management (ISM) protocol. It includes a standalone HII implementation for RAID configuration forms, GPIO library for platform-specific signaling, and persistent metadata journaling for RAID array recovery.
