Adrian Danis 4fe72d09f5 x86: Mechanism for catching GP faults and returning to an error handler 
Provides a mechanism where if af GP fault is potentially expected it can be caught
and the calling code returned to. The GP happening can be detected by setting
a specific return to handler and additionally by the return to handler being
cleared if a GP happened.

We welcome contributions to seL4. Please see the website for information on how to contribute.

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.
