IioCfgUpdateDxeLightningRidgeEXRP

Overview

IioCfgUpdateDxeLightningRidgeEXRP sends IIO (Integrated IO) configuration data tables to the UBA protocol for the Lightning Ridge EXRP platform. It delivers four GUID-identified configuration blocks covering socket configuration, miscellaneous config, PCIe register updates, and extended config. Each block contains PCIe register AND/OR mask updates applied to IIO root ports across all processor sockets. The UBA core applies these config updates during IIO initialization.

Key Functions

• ModuleEntryPoint -- Entry point; initializes UEFI globals, locates HOB list and UBA protocol, calls SetIIOConfigData for all 4 config blocks
• GetHobList -- Locates IIO configuration HOB from system configuration table
• GetDebugLibProtocol -- Locates and caches the DebugLib protocol interface
• DebugPrint -- Debug output via DebugLib protocol
• DebugAssert -- Assertion handler via DebugLib protocol
• IsGuidEqual -- Two-64-bit GUID comparison

Dependencies

• UEFI Boot Services (gBS->LocateProtocol, gBS->AllocatePool)
• UBA Protocol ({E03E0D46-5263-4845-B0A4-58D57B3177E2})
• IIO Configuration Data Block GUIDs (4 config blocks):
  • {6FE6C559-4F35-4111-98E1-332A251512F3} (socket config)
  • {0F722F2A-650F-448A-ABB7-04EECD75BB30} (misc config)
  • {EBD11A00-8C5C-4F71-BB9E-5394032B01F4} (PCIe config)
  • {123BD082-3201-465C-B139-0CB8C77208F8} (extended config)
• DebugLib Protocol
