Debug GEM5 Source Using Eclipse: A Quick Tutorial

如何使用 Eclipse 调试 GEM5 代码

Environment Configuration

Note that this is just the environment we are currently working under, and it’s at your own risk to adopt the other environments.

• OS：Ubuntu 16.04.1 Desktop
• Eclipse： eclipse-cpp-2018-12-R-linux-gtk-x86_64
• Gem5 Commit ID：c428c220fd351626e2ee0005dda696940261793b
• OpenJDK: 1.8.0_191

Steps to Work

1. Build gem5.debug

   git clone https://github.com/gem5/gem5
   cd gem5
   scons build/X86/gem5.debug -j$(cat /proc/cpuinfo | grep "processor" | wc -l)
   cd util/term
   make && sudo make install
   cd ../../..
   

2. Install JRE

   sudo apt install default-jre
   

3. Setup eclipse

   wget http://ftp.yz.yamagata-u.ac.jp/pub/eclipse/technology/epp/downloads/release/2018-12/R/eclipse-cpp-2018-12-R-linux-gtk-x86_64.tar.gz
   tar -xvzf eclipse-cpp-2018-12-R-linux-gtk-x86_64.tar.gz
   

4. Config eclipse

   1. Open eclipse

      cd eclipse
      ./eclipse
      

   2. Import gem5.debug as the C/C++ executable file

      Menu -> File -> Import -> C/C++ folder -> C/C++ Executable -> Select gem5.debug

      eg. at gem5/build/X86/gem5.debug

      
      

   3. Create a lauch configuration

      Just Leave every thing AS IT IS.
      

5. Debug configurations
   1. Set arguments for gem5.debug to bootup gem5 in the way you expected.
      
   2. Set the variable M5_PATH to point out the location of your binaries if you are to use gem5 FS mode.
      
   3. Tell Eclipse where to lookup the source.
      
      eg. at gem5/build/X86
6. Just be ready for THE ENDLESS NIGHTMARE gem5 will bring!
