CVS is finally retired at linux-mips.org. Currently the main project, the MIPS kernel, has been switched to git; others will follow. The plan is to leave anonymous CVS archive enabled for a while.
For those who always want to stay on the bleeding edge, and want to avoid having to download patch files or full tarballs, we also have an anonymous CVS server. Using CVS, you can checkout the Linux/MIPS source tree with the following commands where you insert linux, libc, gdb or faq for <repository>.
cvs -d :pserver:firstname.lastname@example.org:/home/cvs login (Only needed the first time you use anonymous CVS, the password is "cvs") cvs -d :pserver:email@example.com:/home/cvs co -r <tag> <repository>
The "linux" repository contains a linux_2_2, linux_2_4 branch and Linux 2.6 on the trunk.
There is a mailing list for information on what gets committed to this repository.
There is also the "malta/linux" repository which is a special tree especially tuned for stability on Malta. It's usually quite far behind the main linux repository and is being phased out in favor for full-blown Malta support in the main linux CVS tree. To checkout a stable 2.4 kernel use the tag MaltaRef_2_4 and for 2.6 MaltaRef_2_6.
More on a historical note, there also is a linux-2.0 repository. The CVS Linux 2.0 version is a backport of the massive MIPS improvments during the 2.1 series which was created for Cobalt when it became clear that 2.2 would not be released in time to ship with the Cobalt products. Thus it only supports the Cobalt Qube and Raq.
Via cvsweb, you have direct access to the new Linux/MIPS kernel sources, and a few other projects hosted in the same CVS archive. The intuitive interface allows you to follow the development at the click of your mouse.
CVS over Rsync
The CVS repository can also be fetched using rsync:
rsync -avz --progress --stats rsync://ftp.linux-mips.org/cvs/linux /local/directory rsync -avz --progress --stats rsync://ftp.linux-mips.org/cvs/CVSROOT /local/directory
You can then check it out using:
cvs -d/local/directory co linux (optionally, throw in -r linux_X_Y_Z for a specific branch)
