Getting gem5

The latest gem5 source code (including the encumbered files) is available via our Mercurial repository host at http://repo.gem5.org. It is strongly recommend that you get a copy of gem5 by using Mercurial. You can get more info about the repository and Mercurial here. Steps for getting a copy of the source code:

  • Install mercurial (hg). This is available in the mercurial package on Ubuntu and Redhat and OS X Fink.
  • After you clone the repository you can update it by typing hg pull and hg update. Read the documentation on this page for more info on using Mercurial.


If you want to download gem5 without installing Mercurial, you can get a tarball. But it will be more difficult to merge in changes when you need to update to new version. The stable repository is available via this link. The development repository is available via this link.

Useful Software not in Mercurial

Full-System Stuff

You would need one or more of the following files to full system simulations using gem5. If you download these files, read this page for instructions on how to install these files.

  • Alpha
    • Full System Files -- Pre-compiled Linux kernels, PALcode/Console code, and a filesystem
      • Unchanged since M5 2.0 beta 3. If you already have these you don't need them again.
    • linux-dist -- Everything you need to create your own disk image and compile everything in it from scratch
  • ARM
    • ARMv8 Full-System Files -- Pre-compiled kernel and disk image for the 64 bit ARMv8 ISA.
    • VExpress_EMM kernel w/PCI support and config -- Pre-compiled Linux 3.3 VExpress_EMM kernel that includes support for PCIe devices, a patch to add gem5 PCIe support to the revision of the vexpress kernel tree and a config file. This kernel is needed if you want to simulated more than 256MB of RAM or networking. Pass --kernel=/path/to/vmlinux-3.3-arm-vexpress-emm-pcie --machine-type=VExpress_EMM on the command line. You'll still need the file systems below. This kernel supports a maximum of 2047MB (one MB less than 2GB) of memory.
    • New Full System Files -- Pre-compiled Linux kernel, and file systems, and kernel config files. This includes both a cut-down linux and a full ubuntu linux.
    • Old Full System Files -- Older pre-compiled Linux kernel, and file system. New users should use package above. This wil likely be removed soon.
    • BBench for gem5 -- Full-system Android files and BBench, a web-browser benchmark.
    • AsimBench for gem5 -- Full-system Android files for AsimBench, a benchmark suite containing various types of mobile applications.
    • Tarballs of generic file systems are available from Linaro. Scroll down to the Developers and Community Builds section. Some work will be required to make these suitable for simulation, but they're a reasonable starting point.
  • X86
    • Full System Files -- The kernel used for regressions, an SMP version of it, and a disk image
    • config files -- Config files for both of the above kernels, 2.6.25.1 and 2.6.28.4
  • (The mkblankimage.sh script to create a blank disk image that used to be downloadable here is now included in the m5 repository, in the util directory.)
