Linux Cross Reference

LXR (formerly "the Linux Cross Referencer") is a software toolset for indexing and presenting source code repositories. LXR was initially targeted at the Linux source code, but has proved usable for a wide range of software projects. lxr.linux.no is currently running an experimental fork of the LXR software.Browse the codeThese are the browsable source code repositores at lxr.linux.no:

• Linux 2.6.11 and later
• Linux 2.5.0 - 2.6.11
• Linux 0.01 - 2.4.31
• SYSLINUX
• coreboot (current tree)
• coreboot v2 (formerly LinuxBIOS v2)
• coreboot v3 (formerly LinuxBIOS v3)
• Mac OS X Darwin/xnu
• Perl

LXR Source codeFor the interested, the source code is available as a git repository at git://lxr.linux.no/git/lxrng.git. Not all of the functionality present in mainline LXR is available in this version, and the documentation is unfortunately rather sparse. Don't hesitate to contact lxr@linux.no with any questions, though.
