Overview

This GUID-named DXE driver provides a REST-style HTTP command interface for managing NVDIMM (Non-Volatile DIMM) modules via serial I/O on the Lenovo HR650X platform. It responds to URL-encoded requests on the "NVMDIMM_IFRDATA" path and dispatches NVDIMM management commands (opcodes 0xE1-0xF9) to the underlying NVDIMM hardware.

The module contains 207 functions (96 entry points + 111 subroutines) covering UART/COM1 serial initialization at 115200 8N1, protocol interface installation for NVDIMM access, and command parsing/routing for NVDIMM management over a serial REST interface.

Key Functions

• NvmdimmInit -- UART/COM1 initialization and protocol location
• NvmdimmInstallProtocols -- Installs NVDIMM access protocols
• NvmdimmCommandDispatch -- REST command parsing and routing (opcodes 0xE1-0xF9)
• NvmdimmSerialRead/Write -- Serial I/O over COM1 (0x3F8-0x3FD)
• NvmdimmFirmwareInterface -- NVDIMM firmware interaction layer
• ModuleEntryPoint -- Standard UEFI DXE entry point

Dependencies

• UEFI Boot Services / Runtime Services
• UART 16550-compatible serial controller (COM1, I/O 0x3F8)
• NVDIMM platform protocols
• Intel NVDIMM firmware command interface
