OpalSecurity

Overview

This DXE driver provides TCG Opal Storage Security Protocol support for self-encrypting drives (SEDs) conforming to the TCG Storage Security Subsystem Class (Opal SSC). It follows the UEFI driver binding model with OpalSecurityDriverInit (entry point), OpalSecurityBindingStart (connect to Opal-capable device), and OpalSecurityBindingStop (disconnect). The module communicates with storage devices using the TCG Storage IF-SEND/IF-RECV protocol at Level 0 for security protocol discovery to identify Opal-capable devices.

Key Functions

• OpalSecurityDriverInit -- Module entry point; installs the Opal Security protocol on a new handle
• OpalSecurityBindingStart -- Binds to an Opal-capable storage device and performs Level 0 discovery
• OpalSecurityBindingStop -- Unbinds from an Opal storage device
• OpalReadCmosDebugLevel -- Reads the Opal debug level from CMOS configuration
• OpalGetHobList -- Retrieves the HOB list for platform configuration data

Dependencies

• TCG Storage Protocol (IF-SEND/IF-RECV)
• Opal Storage Protocol (OPAL_STORAGE_PROTOCOL)
• UEFI Boot/Runtime Services
• CMOS access for debug configuration

Platform

X64 UEFI DXE driver, PE32+ format, 5 sections (.text, .rdata, .data, section_3, .xdata). Part of AmiModulePkg.
