openprot-mctp-server

Platform-independent MCTP server core, ported from the Hubris mctp-server crate.

Overview

This crate implements the central MCTP server logic: listener and request handle allocation, inbound message routing, outbound message fragmentation/sending, and timeout management for pending receive calls. It is generic over transport bindings via the mctp_stack::Sender trait.

Key Types

  • Server<S, N> — the MCTP server, generic over Sender (transport) and N (config)
  • ServerConfig — configuration constants (MAX_REQUESTS: 8, MAX_LISTENERS: 8, MAX_OUTSTANDING: 16, MAX_PAYLOAD: 1023)
  • RecvResult — result from a receive operation

Modules

  • dispatch — IPC request dispatcher; decodes wire-protocol requests and calls the corresponding Server methods

Architecture

The server wraps the mctp-lib Router as its packet processing engine. Inbound packets are fed via Server::inbound(), and Server::update() drives pending-recv fulfillment. The dispatch module bridges IPC wire-protocol messages to server operations.

Dependencies

  • openprot-mctp-api — API traits and wire protocol
  • mctp-stack (mctp-lib) — Router, Sender, fragmentation, serial/I2C handlers
  • mctp — core MCTP types (Eid, MsgType, Tag)
  • heapless — no_std collections
