The DRI project has moved its CVS services to http://dri.freedesktop.org/ , to reduce the pains related to SourceForge's overloaded CVS services. The DRI project's CVS tree remains the upstream provider of the DRM (and is thus what is referred to as "DRM CVS"), but the xc tree is now obsolete and X.Org is the canonical source of DRI-enabled DDX drivers and GLX support.

To check out DRM CVS from freedesktop.org anonymously, first you must login:

cvs -z3 -d:pserver:anonymous@dri.freedesktop.org:/cvs/dri login

Hit Enter for the password.

Then, check out the drm module:

cvs -z3 -d:pserver:anonymous@dri.freedesktop.org:/cvs/dri co drm

If you wish to check out a branch of the old xc DRI CVS, use the -r tag, e.g.:

cvs -z3 -d:pserver:anonymous@dri.freedesktop.org:/cvs/dri co -rmach64-0-0-6-branch xc

You'll also need a copy of the Mesa CVS tree:

cvs -z3 -d:pserver:anonymous@dri.freedesktop.org:/cvs/mesa login    
cvs -z3 -d:pserver:anonymous@dri.freedesktop.org:/cvs/mesa co Mesa

If you are a developer, CVS access is through ssh. Set CVS_RSH=ssh in your environment. Then, you can check out using

cvs -z3 -d:ext:username@dri.freedesktop.org:/cvs/dri co xc
cvs -z3 -d:ext:username@dri.freedesktop.org:/cvs/dri co drm
cvs -z3 -d:ext:username@dri.freedesktop.org:/cvs/mesa co Mesa
