The second day of XDC 2008 was filled with quite a bit of technical information (as you can see from the Wiki notes page) ranging from the DRI2 infrastructure and talking about its event ring buffer and simpler DDX driver requirements to discussing video playback APIs. However, there are a few bits of information that are relevant to the community at large.
As was mentioned yesterday, the X Developers' Conference (XDC) is taking place this week at the Googleplex. There's only around 50 developers in attendance, but for everyone else there still is a flow of information to gather. A few Google employees had recorded each of the talks from the first day, however, they aren't yet available on You Tube or Google Video. Unfortunately, it doesn't look like Google will be recording the X videos for the second and third days of this conference. Red Hat's Adam Jackson, however, has been summarizing the highlights of each talk in near real-time and has been uploading it to the X.Org Wiki.
The 2008 X Developers' Conference (XDC) is kicking off this morning at the Googleplex in Mountain View, California. The XDC (not to be confused with XDS, the X Developers' Summit) is made up of a variety of presentations and lightning talks surrounding X.Org and upcoming work done by this important free software project.
Back on the 4th of February, Kristian Høgsberg began merging his new DRI2 components. This initial DRI2 (Direct Rendering Infrastructure 2) work was made up of the DRI2 module, glxdri2 to GLX, and DRM/Mesa patches. Today Kristian has merged his last major part of DRI2 and that is the direct rendering support. With this new code, it's now possible to do directed rendering to redirected windows! This directed rendering to redirected windows support even works with Compiz and other OpenGL window managers using the GLX_EXT_texture_from_pixmap extension. However, to reach this state the DRI interface was broken. Kristian's announcement can be read on the DRI devel mailing list. The only X.Org video driver using DRI2 right now is the Intel batchbuffer branch for xf86-video-intel.
Thanks in large part to the release leadership of Adam Jackson, a new development X server is now available that ultimately will become known as X Server 1.5.0. This new xorg-server release, v126.96.36.1991, has a plethora of changes ranging from fixing memory leaks to EXA improvements. In total there are hundreds of changes to be found within xorg-server 188.8.131.521, with the complete list being available in the X.Org mailing list. More information on the plans for X.Org 7.4 can be found in this article.
With Red Hat's Adam Jackson being interested in shipping X.Org 7.4 for Fedora 9, he has stepped up as becoming the release manager of this next X.Org release and has put together a schedule that will allow this to become possible.
While the XvMC (X-Video Motion Compensation) extension is reliable for offloading MPEG video decoding to the GPU, its limitation is that it only supports MPEG video formats and nothing more. We had expected XvMC not to be around much longer, since Intel has been devoting resources in creating a new video extension for X.Org. This new video work of Intel's is known as VA-API, or Video Acceleration API, and is still quite early in development. VA-API, however, will be able to handle offloading more tasks along with support for all of the latest video standards (MPEG-4, H.264, VC-1, etc). VA-API is not based upon XvMC but is written from scratch.
Remi Cardona is currently talking at FOSDEM 2008 in the X.Org development room about Metisse. For those that don't know, Metisse is an open-source X Window System that was conceived as a French research project (and is incorrectly considered competition to Compiz). Remi's talk is on the features of Metisse, various desktop demonstrations, and bringing Metisse and X.Org together. Some of the items he shared for the Metisse road-map include adding a configuration interface, Expose-like features, FreeDesktop.org integration, and then X.Org integration. This research project is also looking at collaborative features such as window sharing between computers or other mobile devices, etc.
Not that you really would have expected X.Org to ship next month as planned, but X.Org 7.4 looks like it may now be released in May. The original plan for X.Org 7.4 was to release it in February, but that was when X.Org 7.3 was planned for August though it didn't make it out the door until September. With a six month release cycle, March was the new strike point for this X.Org update. We're now running into late February and X Server 1.4.1 hasn't even been released yet, which is a maintenance update that was supposed to arrive last November. There are still five bugs blocking X Server 1.4.1. Red Hat's Adam Jackson has updated the 7.4 Wiki page to reflect that X.Org 7.4 is now planned for a May release. Hopefully that time-frame is met, but that could turn into a June release. If meeting their ideal six month release cycles, X.Org 7.5 would then be released in November or December, but because of the holidays that is likely a Q1'09 release.
Kristian Høgsberg, the creator of AIGLX, has announced on the X.Org mailing list that he is beginning to merge his new DRI2 components. This work includes the new DRI2 module, glxdri2 to GLX, and DRM/Mesa patches. The DRI2 work is ready for early adopters, but is able to safely reside next to XF86DRI. With an Intel DDX patch in the intel-batchbuffer git branch, the xf86-video-intel driver will have a DRI2 option to manually enable the DRI2 module.
For those not satisfied by RandR 1.2 or just wish to live on the cutting-edge of X.Org developments (like us), this week on the X.Org mailing list has been a discussion among driver developers surrounding RandR 1.3. RandR 1.3 is the next update to the Resize and Rotate (RandR) extension that allows for resizing, rotating, and reflecting of the X screen. With the RandR 1.2 update it had introduced display hot-plugging support. When it comes to features, RandR 1.3 is most notably expected to introduce GPU object support. This GPU object support is another layer between the X screen and the CRTCs. Ultimately, this should allow multiple GPUs to be merged into a single X screen.
It's coming a month late, but today X Server 1.4.1 has been pre-released. The xorg-server is now at version 184.108.40.206 and contains over two dozen fixes since X Server 1.4.0. The X Server 1.4.1 pre-release notes and download link is available from the mailing list announcement. On the xorg-server 1.4.1 blocker bug are still five outstanding bugs.
Sascha Hlusiak has announced the release of xf86-input-joystick v1.3.1, which is for providing joystick input support on X.Org 7.3. What makes this joystick driver release newsworthy is that it now provides evdev integration. If you're not familiar with evdev, it's the generic input driver for X.Org, and commonly is used for accessing USB input devices. This new joystick driver supports evdev but has fall-back support for the Linux joystick interface. Thanks to the evdev support, the xf86-input-joystick driver can now be auto-loaded with hot-plug support through HAL. A few other changes also make up the xf86-input-joystick v1.3.1 release, which is detailed in the release announcement.
There's still one bug left before the release of X Server 1.4.1, but Daniel Stone has announced on the X.Org mailing list that X Server 1.5 will no longer contain any "input hotness". Specifically, XKB 2 and Xi 2 were planned but that has been postponed until at least X Server 1.6. This delay has occurred because these changes will require quite a bit of work with how input events are processed and related MPX changes. Expect new X.Org input hotness then towards the end of 2008.
X Server 1.4.1 was originally slated for release on the first of November, then Daniel Stone had pushed the release back to November 11, but that didn't happen either. The X Server 1.4 Wiki page still reflects a release date of November 11, but that's passed by nearly a month.
X.Org 7.3 was released two months ago, and scheduled to be released today was X Server 1.4.1. This release is supposed to address some of the issues that had come up with X Server 1.4.0; however, it looks like this release will be delayed once again. The X Server 1.4 Wiki page still shows the release date as November 11, but there are a number of open bugs remaining. The xorg-server-1.4.1 blocker bug has five dependent bugs open with only two being resolved. These five remaining bugs are for memmove in SetKeySymsMap, EXA corruption, EXA negative tile coordinates, a KDE Konqueror X11 issue, and input events being duplicated across different windows. Nothing has been brought up on the X.Org mailing list yet, but it doesn't look like X Server 1.4.1 will be released today. In the meantime, you may want to read The Degrading Quality Of X.Org Releases?
As opposed to being pushed out on the first of November, Daniel Stone (the release manager), has delayed the release of X server 1.4.1 by ten days. X server 1.4.1 will now be released on November 11 (permitting no more delays) and will contain a variety of bug-fixes and input fixes for extended events currently found in X server 1.4.0. The list of waiting and merged patches as well as other X server 1.4 details can be found on the X.Org Wiki. With X.Org currently being criticized for its degrading release quality, this X server 1.4.1 delay is hopefully good news and will result in a more polished release.
Last month at the X Developer Summit in Cambridge, Eric Anholt, Adam Jackson, and Daniel Stone had talked about the future of X.Org releases for the next year. Over the weekend, Daniel Stone had updated the XDS 2007 Notes at X.org with the latest plans for X.Org 7.5. The current schedule for X.Org include the X server 1.4.1 release coming out on the first of November followed by X server 1.5.0 in March of 2008. Planned for X.Org 7.4 and X server 1.5 is XGE, XACE, RandR 1.3, PCI rework, XKB 2, _X_EXPORT, DRI memory manager, GLX 1.4, and Glucose.
On the X.Org mailing list, Alan Coopersmith had raised concerns over the release criteria for X11 and how with recent releases (namely X.Org 7.3), the de facto standard for making a release was far from being met. Alan, Sun's X engineer, had listed the release criteria as the blocker bug list being cleared, the complete tree/release modules being build-able on at least one platform, XTS successfully running on at least one platform, and the documentation being updated and then released. X.Org 7.3 was released eight days late and failed to fully meet any of the requirements -- some X.Org 7.3 driver packages didn't even build against the respective X server.
The open-source RadeonHD driver that is even supports the Radeon HD 2900XT has continued over the past few days with a number of changes. Among these changes has been adding identification support for new GPUs (including the Apple MacBook Pro 2.2), removing some experimental checks, adding the conntest utility, and this morning AMD's AtomBIOS parser was merged into the xf86-video-radeonhd git tree. This AtomBIOS parser was written internally at AMD but is now available as open-source code. Check out the RadeonHD git code if you want to try out an open-source driver for ATI's R500 and R600 graphics processors.
Well, the delay we told you yesterday ended up being a one-day delay. As of this morning, X.Org 7.3 and X server 1.4 have been officially released. You can find the download details and other information on the X.Org Wiki.
X.Org 7.3 and X server 1.4 were originally scheduled for release towards the end of August, but bugs had pushed back its release to September 5. Well, the day is now over and X.Org 7.3 is not to be found. The 7.3 release tracker bug still has eleven bugs currently outstanding. The X.Org mailing list hasn't announced a new release date yet. Additional information on X.Org 7.3 is available from its Wiki page and our X.Org 7.3 Preview.
If you haven't noticed, the release of X.Org 7.3 has been delayed by at least a week. Eric Anholt, the X.Org 7.3 release manager, had pushed the X.Org 7.3 release back by at least a week due to show-stopping bugs. Eric has set the new X.Org 7.3 release date for September 5th. At present there are about seven bugs holding up this release. Additional information can be found on the X.Org mailing list.
X.Org 7.3 will be released later this month, and now Daniel Stone has updated the X.Org Wiki with a page for the X.Org 7.4 release. With the six month release cycle, X.Org 7.4 is planned for release in February of 2008. Some of the features so far on their planning page includes Multi-Pointer X which provides multiple cursor support, support for UnixWare, SELinux security module, and a Solaris Trusted Extensions security module. The two security modules will use XACE (X Access Control Extension). Find out more on the Wiki.
It's been all quiet on the XGI front for quite a while with most of their talent having been acquired by ATI last year, but Ian Romanick has announced today on his new blog that XG40 DRM support has been added to the mainline tree. Graphics cards that use the XGI XG40 GPU include the Volari V3EX, V3XT, V5, and V8. Now you can use the open-source DRM and DDX from the FreeDesktop.org git and with the closed-source DRI can now have acceleration with the different XG40 graphics cards. Due to licensing restrictions from SGI, XGI Technology cannot open the code to the DRI driver.
X.Org 7.2 has finally shipped with improvements on stability, correctness fixes, improved auto-configuration options, enhanced support for Compiz and Beryl, and much more. More information is available in the X11R72 Press Release.
A third and final release candidate has been issued today by X.Org in the X11R72 branch. While X11R72 final was supposed to be out towards the end of November, it has now slipped to December 11. The changes in X.Org 7.2 RC3 are minimal. Updated since X.Org 7.2 RC2 is XCB, libX11, libXfont, libpthread-stubs, rendercheck, sessreg, twm, util-macros, xdm, xfs, xf86-video-i128, xf86-video-mga, xf86-video-nv, xf86-video-s3, xf86-video-sis, xf86-video-tdfx, xf86-video-vesa, and xorg-server. This release candidate can be found on the mailing list.
X.Org Foundation has today announced the release of X11R7.1. X.Org v7.1 is a modularized roll-up release that comes five months after the X11R7.0 release. Some of the improvements include new embedded server and driver features, 64-bit platforms, enhanced operating system support, and accelerated indirect GLX support. X 7.1 also demonstrates the benefits of modularization. More on this is available in the X.Org press release.
Adam Jackson has passed along word that X.Org v7.1 is pretty much done at this point and is expected for release on Monday, May 22, 2006. Meanwhile, X.Org v7.2 already has a tentative release date of November 17, 2006. The first branch nomination for X.Org v7.2 is on September 15, and then the first release candidate is expected for presentation on October 6. Look for the X.Org v7.1 release coming out this Monday.
