Revision as of 23:01, 29 August 2013

Welcome to the gem5 documentation. We've worked hard to add and organize everything in a more reasonable format, however we still haven't got to everything. All the documentation is a wiki, so we encourage you to add and edit sections as you find omissions and bugs.

Old Documentation: We have some old documentation and have been trying to move everything to the new format, but we haven't quite succeeded yet. If you don't find the answer you're looking for here, you might want to check the old documentation.

Getting Started

  1. Introduction - A quick introduction to gem5.
  2. Source Code - Information about the source code itself.
  3. Dependencies - Things you'll need that aren't part of gem5 itself.
  4. Build System - How to run or modify gem5's build system.
  5. Full System and Benchmark Files - Disk images for operating system and benchmark applications, and how to install them.

Running gem5

  1. Running gem5 - Starting a simulation from the command line.
  2. Checkpoints, Fast Forwarding - How to create Checkpoints, restore the checkpointed state, fast forward simulation.
  3. Regression Tests - Running the regression tests.
  4. SimObjects - What SimObjects are and how they work.
  5. Configuration Scripts - This and the next section need to be merged.
  6. Simulation Scripts Explained
  7. Architecture Support -- What architectures are supported by gem5 and what features of them are implemented
  8. Visualization -- Tools to help visualize what is going on in a system

Workloads

  1. Compiling - How to compile workloads to run within gem5.
  2. Multi-programmed - Multiprogrammed workloads in SE mode.
  3. Multi-threaded - Multithreaded workloads in SE mode.
  4. Benchmark suites
    1. SPEC - SPEC benchmarks in SE mode.
    2. SPLASH - SPLASH benchmarks (SE or FS mode?)
    3. PARSEC - PARSEC benchmarks in FS mode.
  5. Disk images - Setting up a disk image.
  6. Linux kernel - Preparing a Linux kernel for use in gem5.
  7. m5ops - How to talk to the simulator from within a simulated workload.

Development

  1. Functional Testers
  2. Debugging - features designed specifically to help you figure out what's going on.
