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.
• 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
