The seL4 Repository (with realtime extensions)

This repository contains the source code of seL4 microkernel, with currently in development real-time extensions.

There are no verification guarantees on this branch, although it is scheduled to be verifified in the future.

Currently the only platforms supported on this branch are x86 (processors with TSC-deadline mode), imx6 and odroid-xu. Other platforms do not compile.

This repository is usually not used in isolation, but as part of the build system in a larger project.

Repository Overview

  • include and src: C and ASM source code of seL4
  • tools: build tools
  • libsel4: C bindings for the seL4 ABI
  • manual: LaTeX sources of the seL4 reference manual

Build Instructions

tl;dr:

TOOLPREFIX=arm-none-eabi- ARCH=arm PLAT=imx6 ARMV=armv7-a CPU=cortex-a9 \
make

The kernel source requires a cross-compiler for the target architecture. To build using make, follow these instructions:

  • Ensure that the appropriate cross-compiler for your target architecture is installed.

  • Set the TOOLPREFIX environment variable to your cross-compiler's prefix. E.g. arm-none-eabi-.

  • Set the ARCH, PLAT, ARMV and CPU variables for the intended target architecture and platform, chosen from the following lists:

    ARCH PLAT ARMV CPU
    arm imx31 armv6 arm1136jf-s
    arm omap3 armv7-a cortex-a8
    arm am335x armv7-a cortex-a8
    arm imx6 armv7-a cortex-a9
    ia32 pc99

  • For a debug build, append DEBUG=y and to see serial output additionally append CONFIG_KERNEL_EXTRA_CPPFLAGS="-DCONFIG_PRINTING=y -DCONFIG_USER_STACK_TRACE_LENGTH=16".

See the seL4 website for more comprehensive build instructions.
