Description

+

+ Request serialization protocol used by edk2 firmware to communicate + between normal mode and management mode ('MM' for short). +

+

+ The QEMU UEFI variable store implementation reuses the request + serialization protocol for firmware ↔ QEMU communication. +

+

+ There are three packet types (32-bit integer in little endian byte + order): +

+
    +
  • RESET (1) - machine reset
    • +
  • REQUEST (2) - normal mode → management mode request message
    • +
  • REPLY (3) - management mode → normal mode response message
