Zack Rusin, a well known employee of Tungsten Graphics (well, VMware), has announced quite the present for Mesa developers and those looking forward to the widespread adoption of the Gallium3D graphics driver architecture. Tomorrow he will be pushing out perhaps the most interesting state tracker yet, one for OpenVG.
It was just three months ago that Mesa 7.3 was released and then work on stabilizing this graphics stack to form Mesa 7.4 began. When the development began on Mesa 7.5, the Gallium3D architecture was merged to master. This work soon will appear in a released version of Mesa.
In late December AMD had released open-source R600/700 3D code and a month later they released the 3D documentation that covers these Radeon HD 2000/3000/4000 series graphics cards. The initial code drop didn't do much good for end-users as they couldn't do much more than render a couple triangles, but over the past few months the open-source developers have been working on the proper Mesa support for the R600/700 graphics cards in a private code repository. Now this code may finally be pushed out to the general public in the near future.
Just a bit more than two months have passed since Mesa 7.3 was released (and about one week since the first 7.4 release candidate), but this evening Brian Paul announced the final release of Mesa 7.4. This new Mesa release incorporates bug-fixes since the 7.3 release. Mesa 7.3 introduced the 3D component for providing DRI2 support, the Graphics Execution Manager for memory management with supported hardware drivers, and improved support for the GL Shading Language.
It has been a number of months since version 0.2 of Gallium3D was declared, but today Keith Whitwell finally bumped the version to 0.3. While Gallium3D isn't yet in a state for end-users, may changes have went on since the creation of the Gallium3D v0.2 branch. Due to numerous interface changes, the Gallium3D version was bumped.
FreeDesktop.org hacker Zack Rusin has provided an update on his blog about some of his recent activities when it comes to Gallium3D.
Back in February we talked about the work that David Airlie is doing to rewrite the ATI Radeon driver for Mesa. Soon now it looks like this rewritten code may land in the mainline Mesa code-base once a few more items are addressed. The rewrite of this open-source ATI 3D support brings buffer management support for all supported ATI hardware, DRI2, Frame Buffer Objects, and all of this work is a prerequisite for having kernel memory management (such as with GEM).
Mesa 7.3 was released back in January and was branched from the master Git tree so that it can be stabilized further and go on to form Mesa 7.4. Well, nearly three months later, Mesa 7.4 is getting close to being released. On this Friday evening, Brian Paul has announced the first release of Mesa 7.4.
Gallium3D recently landed in Mesa's mainline code-base and work on it continues to move forward in a steadfast manner. Committed to Mesa's master branch last night for Gallium3D were state trackers for Xorg and DRI2.
TTM, or Translation Table Maps, the memory manager developed by Tungsten Graphics, is now dead. TTM has been dwindling away since last year when Intel introduced the Graphics Execution Manager (which has since entered the mainline Linux kernel), but now the code for this memory manager has been dropped from Mesa's Intel driver.
Gallium3D, the 3D graphics driver that has long been in development by Tungsten Graphics, has finally entered the mainline Mesa code-base! Gallium3D has a lot of capabilities and will be of much benefit to Linux desktop users once all 3D drivers have been ported to this new architecture (for more information read our articles or the Tungsten Wiki). We shared yesterday that Gallium3D was in the process of being merged and that is now completed within Mesa's master branch. Gallium3D will now be a feature for Mesa 7.5/7.6.
We have known that Gallium3D would soon be landing in Mesa and now it looks like that will take place this week. In fact, Gallium3D is in the process of being merged to the master development branch right now and should be complete within a day or two. Gallium3D will then appear in Mesa 7.5 / 7.6, but not the forthcoming stable Mesa 7.4 release.
Zack Rusin, one of the influential developers behind the Linux graphics scene, has blogged about OpenCL support in the free software stack. Just yesterday we talked about support for OpenCL in GCC, but Zack's work deals with implementing support for the Open Computing Language into the open-source X.Org drivers.
There is now talk on the Mesa 3D development list about the possibility of having a Mesa driver for the Nintendo Wii. Those working on developing custom games for this console platform have already experienced some success in bringing OpenGL to the Wii through the use of Mesa.
Mesa 7.3 was only released a few days back and then the branch for the stabilized Mesa 7.4 created, but new work for Mesa 7.5 has already hit Mesa's Git master branch. The Gallium3D architecture has yet to enter the mainline Mesa code for Mesa 7.5, but still there's new OpenGL extensions and other work worth noting.
Yesterday we talked about Nouveau Gallium3D video improvements that are allowing 1080p video clips to now play with this open-source driver stack. Today there's an ongoing discussion about a proper video decoding interface for Gallium3D.
Just shy of a week since tagging Mesa 7.3 RC2, Brian Paul has announced Mesa 7.3 Release Candidate 3. This third release candidate is made up of a few GLSL changes and some Intel-specific work. Support for RGBA4444 and RGBA5551 texture formats have also been added.
Just five days after announcing the Mesa 7.3 Release Candidate 1 with improved GLSL 1.20 support, Intel GEM support, and Direct Rendering Infrastructure 2 integration, the second release candidate has now surfaced.
As we shared late last week, Mesa 7.3 is getting ready for release with the first release candidate having arrived. Mesa 7.3 will feature improved GLSL 1.20 support, support for the Graphics Execution Manager, and Direct Rendering Infrastructure 2 integration. The stabilized version of Mesa 7.3 will then go to make Mesa 7.4.
It's been over four months since Mesa 7.1 was released and about three months since Mesa 7.2 (the stabilized version of 7.1), but now Mesa 7.3 is getting primed and ready to enter the limelight. As the first step, Mesa 7.3 Release Candidate 1 will be pushed out shortly.
It's taken an eternity (well, to the Linux community that has been eagerly awaiting code and documentation since very early this year when it was first promised), but it looks like the open-source 3D support for the ATI R600/700 (Radeon HD 2000 through Radeon HD 4000 series) graphics processors may finally be coming soon!
Following last month's release of Mesa 7.1, Tungsten Graphics began working on Mesa 7.2, which is a stabilized version of this OpenGL implementation that had picked up 3D support for the ATI Radeon R500 and Intel GMA 4-Series. Mesa 7.1 also marked the switch to an autoconf build system, GL_EXT_texture_from_pixmap extension for Xlib driver, GLSL support for the Intel 965, and various other improvements.
SGI has announced today announced the release of a new version of the SGI Free Software License B. This software license is now nearly identical to the X11 license in use by X.Org. The GLX API and other GLX extensions are now casted under this revised SGI license. Most importantly, the Free Software Foundation approves this relicensing and they have also received praise from the Khronos Group, the company behind OpenGL. The press release in full can be read at the SGI web-site. This license is more "free", which is good news for the X.Org and Mesa communities.
Released in late August was Mesa 7.1, which was the first release of this open-source OpenGL library with an autoconf-based configuration system, various DRI driver enhancements, GL_EXT_texture_from_pixmap extension for the Xlib driver, GLSL for Intel's 965 Chipset, and ATI R500 series support. This release was also important since it was a prerequisite for the X.Org 7.4 / X Server 1.5.0 release. Out this weekend though is Mesa 7.2 Release Candidate 1.
With the Gallium3D status update provided during XDS 2008 and other recent work for this advanced 3D graphics architecture (such as enhanced debugging capabilities), we were left to wonder where the generic GPU video decoding is at in its implementation. Today we have an answer.
By now most Linux users should have heard of Gallium3D, but if you haven't, it's a new library being developed by Tungsten Graphics. Gallium3D provides a number of significant advantages over the current architecture as it simplifies driver development and makes it very easy for these Gallium3D-powered drivers to support new graphics APIs. There are, however, other advantages to Gallium3D and one of them is the enhanced debugging capabilities.
During FOSDEM this year, Keith Whitwell had provided a status update on Gallium3D and where they were at as of February. However, a lot has changed since then. Today at XDS 2008, Keith has provided a new status update of where they are at with this new driver infrastructure. Below are our notes from this talk as well as the following talk delivered by Tungsten's Jakob Bornecrantz.
Earlier this month we shared that X.Org 7.4 will lose DRI2 support. Direct Rendering Infrastructure 2 (DRI2) was just conceived one year ago and X.Org 7.4 would have been the first release with this technology that allows for directed rendering to redirected windows. DRI2 though was delayed though since it had to be reworked due to Intel switching memory managers from TTM to GEM (Graphics Execution Manager). The first bits of the revised code have now hit the master git tree for Mesa and the X Server.
Tungsten's Brian Paul has today announced the release of Mesa 7.1. New in this open-source library used by Linux graphics drivers for providing OpenGL support is autoconf-based configuration, assorted DRI driver enhancements, reduced dependencies between the X server and Mesa, GL_EXT_texture_from_pixmap extension for Xlib driver, GLSL (GL Shading Language) support for the Intel 965, and ATI Radeon R500 (X1000) series support. Sorry folks, no OpenGL 3.0 support.
Mesa 7.1 has been in development for a number of months already with the first release candidate having come out in May. However, this update to the open-source 3D graphics library has been delaying the release of X.Org 7.4 as it's a dependency for building the X Server. We wish we could tell you Mesa 7.1 was shipping today, but instead we have another release candidate.
