Getting gem5

We are no longer distributing specific releases of gem5 or M5 as tarballs. The latest gem5 source code (including the alpha-system and encumbered files) is available via our Mercurial repository host at http://repo.gem5.org.

If you want to download the latest stable copy of gem5 without installing Mercurial, you can get a tarball from that site via this link. However, we strongly recommend that you get a copy of gem5 by using Mercurial and the instructions on this page.

This page hosts only useful stuff that is not in mercurial.

Useful Stuff Not In Mercurial

Full-System Stuff

• 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
  • 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.
  • 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.)

Benchmarks

• For information about running Android on gem5 and using the web browser benchmark, see Bbench-gem5.
• SPLASH benchmarks -- See the Splash benchmarks page for more information

Pre-compiled Cross-compilers

Externally supplied cross compilers:

• ARM cross compilers from Code Sorcery -- These are high-quality cross compilers that are updated frequently
• Ubuntu users can simply install the gcc-arm-linux-gnueabi and libc6-dev-armel-cross packages
• MIPS cross compilers from Code Sorcery

All generated with crosstool for x86 linux hosts/linux targets

• Alpha: gcc-3.4.3, gcc-4.3.2, glibc-2.6.1 (NPTL,x86/64), gcc-4.3.2, glibc-2.6.1 (NPTL,x86/32)
• SPARC64
