Mcube Kernel

Operating System Supporting Dynamically Switchable Kernel Models

Description

Mcube Kernel is an operating system for Micro/Monotlithic/MultiKernels. Dynamically switchable kernel models can avoid unnecessary recompile and reboot.

Supporting Compilers and ISAs

• LLVM-6.0.0/GCC-7.3.0 (or later) for X86_64, ARM64 (AARCH64), and SIM (user-level) ISAs
• LLVM-6.0.0/GCC-4.8.4 Extension for AXIS ISA
  • LLVM's ISA name is MAXIS (can be downloaded from https://github.com/pflab-ut/llvm)
  • GCC's ISA name is DOM (not open for public)
• Python 3.6.5 (or later)

Set up Build Environment (Ubuntu 18.04 LTS)

Please execute the following command (root privilege required).

$ make setup

Set up Configuration

Please edit configure file or execute the following command.

$ cp docs/config/ARCH_configure configure

where ARCH_configure is aarch64_raspi3_configure, axis_configure, sim_configure, or x86_64_configure.

ARCH of ARCH_configure is changed to an architecture name of small characters. Details of configure file are explained in Kconfig.

How to Build

First of all you check and modify configure file. If CONFIG_XXX=y, enable the configuration. If CONFIG_XXX=n, disable the configuration. Then please execute the following command.

$ make configure

Otherwise if you would like to use docker, please execute the following command.

$ make docker

If cleaning build files, please execute the following command.

$ make clean

How to Execute

Without Arguments

Please execute the following command in CUI.

$ make run

Please execute the following command in GUI.

$ make grun

With Arguments in SIM Architecture

Please execute the following command in CUI.

$ make run ARGS="arg1 arg2 arg3"
