Rumpk Core (L1)

Language: Nim
Purpose: Architecture-agnostic kernel logic

Module Index

File	Purpose
kernel.nim	Main Orchestrator (kmain)
ion.nim	ION Control Plane & Channel API
fiber.nim	Cooperative fiber abstraction
watchdog.nim	Autonomous Immune System (Healer)
ring.nim	Lock-free Sovereign ring buffers
panicoverride.nim	Freestanding panic handler

Architecture Independence

This folder contains no architecture-specific code. All platform-specific details are handled by the HAL layer (../hal/).

Compile-time architecture selection uses Nim's when defined():

when defined(amd64):
  const CONTEXT_SIZE = 56
elif defined(arm64):
  const CONTEXT_SIZE = 96
elif defined(riscv64):
  const CONTEXT_SIZE = 112

Dependencies

• Imports console_write, rumpk_halt from HAL (Zig L0)
• Imports cpu_switch_to from arch-specific assembly
• Uses mm:arc memory management (no GC)

Build

Built via ../build.sh [aarch64|x86_64|riscv64]
