CE Linux Developer Wiki
This web site has public information about the CE Linux Forum, including source code, information, and documents which may be of general interest to both members and non-members of the forum.

- UPDATE: Unfortunately, due to unscrupulous spamming of this site, in order to edit pages on this site you now need to create a user account. This is free and easy - just go to the UserPreferences page. To just view pages, no account is necessary. Sorry for the inconvenience.
There are 3 main things of interest on this site:
- resource pages - information about and links to technologies and projects of interest for CE products
source code - the main (centralized) outlet for (unmainlined) forum source code is the PatchArchive
- specifications - the forum also produces documents describing technical requirements or desired features for Linux use in CE products
The forum also hosts technical conferences (or sponsors or participates in existing Linux events) and posts technical papers, presentations and other information from those events.
Kernel Patch and Feature Watch List
CELF is now monitoring the status of several out-of-tree kernel patches and features. This page shows the items that CELF members are interested in.
See KernelPatchAndFeatureWatchlist
Embedded Linux Wiki
CELF is creating a vendor-neutral, community-oriented wiki to host information related to the use of Linux in embedded products. CELF member Movial is providing hosting for the site, and CELF itself has contracted with Bill Traynor to be an editor for the site.
The wiki will be a new site especially dedicated to embedded Linux. Much of the existing content of the current CELF public wiki will be moved there. This includes material primarily targeted at system designers and software developers. The new site will include technical information, howto guides, research results and other information useful to make it easier to use Linux in embedded products. Where appropriate, links will be made to existing material -- such as Wikipedia, Sourceforge projects, and news sites (such as LinuxDevices and LWN.net).
CELF is issuing a call for volunteers to join the task force, which will hold its discussions on CELF's developer mailing list at celinux-dev@tree.celinuxforum.org. If you would like to join the task force for the site, please contact Tim Bird at tim.bird (at) am.sony.com.
See EmbeddedLinuxWiki for more information.

CELF Member Project List
ProjectList - (still under construction) This is a list of projects that various companies are interested in. CELF and it's members make no commitment to work on, endorse or promote these projects. This is just our list of things we're interested in.
Miscellaneous

CELF Test Lab
The CE Linux Forum has a test lab, for testing aspects of Linux important for CE products.
See the Open Test Lab web site
Source Code
Over time, the forum has changed its approach to handling software. We started with very large patches in an integrated tree (based on kernel version 2.4.20). With the 2.6 release, we shifted to a mode where individual patches are available against stable kernel.org source trees.
Note that anyone may submit a patch to be included in the CELF patch archive. A patch, submitted thus, might be considered by the forum and end up being ratified as an official CELF "reference implementation". Non-members who submit code to the forum are required to submit it under an agreement at: http://tree.celinuxforum.org/submitter_notice.html
2.6-based patches
PatchArchive - This page has several tables of patches which are being maintained against recent stable versions of the kernel.org (mainline) Linux kernel.
- Please note that some CELF patches have been incorporated into the mainline Linux kernel source tree. Also, please note that we encourage CELF members and others to contribute directly to the primary repository for the project for a particular
technology. (Translation: If there's a SourceForge project for a technology area you are working on, donate the patch there instead of here (but do please put a link to the project from this site).
2.4-based releases
CELinux_040503_Release - This was the "CELF 1.0" release, based on the 2.4.20 kernel.
- The number stands for 2004, May, 3rd release.
SourceTreeInformation - This has some information about the original CELF source tree
ReleaseInfoPage - this has links to other previous releases of the integrated source tree.
Other source-related resources
PatchSubmissionHowto - how to submit a patch to the forum
