Opening Day

access(2) OpenSolaris As you may have noticed, the release of the first big batch of code from OpenSolaris project today is being accompanied by blogs from many of the Solaris engineers. When you read these blogs you'll see most of the engineers are writing about the parts of the code they know best. Unfortunately, for me, that's the parts not yet released. (There are a couple of lines of code here and there from me that I submitted as suggested fixes in bugs I filed, but I've never checked in any code directly to the source tree the released code comes from.)

Why is that? Because of the way Solaris is built - it's not one single monolithic source tree, but instead organized into chunks called "consolidations." Today's first phase is a single consolidation, called "OS/Networking" or ON for short, which contains most of the Solaris kernel, drivers and core utilities. The consolidation most of my work goes into is simply called "X", and includes both the Xsun & Xorg source trees for Solaris, but not the Xsun device modules. Other consolidations include CDE/Motif, JDS, Graphics and Networking drivers, Developer Tools, Administration/Installation, and so on. Each consolidation manages it's own source trees and builds, and delivers the built packages to a central dock where all the consolidations are combined into the Solaris WOS ("Wad of Stuff") which is the CD or DVD set delivered to the users.

Since Solaris is huge, instead of waiting until everything was ready for release, a staged plan was developed for OpenSolaris, starting with the consolidation at the core of the OS and then working out to the higher layers. Now that ON is out and the infrastructure used is set up, we're starting to work out how to release code from other consolidations. Once everything is in place for additional consolidations to be added to OpenSolaris, the next phase will probably be the source trees that come from open source releases and are thus not needing as much work to separate out the bits that can be released from those that can't, and that is expected to include our Xorg server source tree.

Of course, if you want to build Xorg for Solaris, you don't need our changes - there's not actually much you need that's not currently in the X.Org CVS repository on freedesktop.org. There's even stuff there that's not yet in our builds, like the experimental support for building 64-bit Xorg servers for AMD64 machines. Our Solaris builds are based on the Xorg 6.8.2 source tree, with various changes backported from the CVS head, such as the newer ATI, nVidia, and i810 drivers, and a few small customizations. Some of those can be enabled in the open source builds by using the BuildLikeSun Imake option recently added to CVS to document some of our customizations. The rest we'll be working on getting out there later this year.

We've also set up a "X Window System" community on the new OpenSolaris.org website where you can find out more information about the status of our X source releases, and talk to the engineering teams and other users. Come join us over there if this part of OpenSolaris interests you!
