Jack Suann 9f67d21c3d x86: Handle pending interrupt before scheduling thread in handleSyscall 
In handleSyscall the current thread may be preempted to handle a pending interrupt.
With kernel mode interrupts in x86 this handling was delayed until we were about
to switch back to user mode. This change unifies the handling with ARM, where the
interrupt is handled prior to calling the thread scheduler.

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.
