The folks at Tungsten Graphics, which are owned by VMware, have been busy with new software releases so far this summer. Mesa 7.5 is coming along well and the Gallium3D driver architecture is now merged into the Mesa mainline code-base for release with Mesa 7.6. When it comes to Gallium3D an OpenVG state tracker has been released along with two OpenGL ES state trackers to accelerate the OpenGL ES 1.1 and 2.0 APIs. There are also OpenCL and OpenGL 3.1 state trackers under development.
Yesterday afternoon there were two new Gallium3D state trackers released by VMware / Tungsten Graphics for OpenGL ES 1.1 and ES 2.0 support. With these new state trackers there is now OpenGL ES 1.1/2.0 acceleration for any graphics hardware that has a Gallium3D driver. The OpenGL ES state trackers came just weeks after the release of an OpenVG state tracker.
Just minutes after announcing Mesa 7.5 Release Candidate 2, Brian Paul has announced that he is in the process of pushing out Gallium3D state trackers for OpenGL ES 1.1 and OpenGL ES 2.0. These two new state trackers for this forthcoming Linux graphics architecture are coming just two weeks after an OpenVG state tracker was released for accelerating this other Khronos API.
The second release candidate for the forthcoming release of Mesa 7.5 is now available. The first release candidate arrived merely a week ago, but RC2 brings a couple more fixes to the table. There is an ATI R300 series fix, a few fixes for the Intel 3D driver, and Mesa has a fix for a texture memory leak.
Mesa 7.5 was supposed to be released in early April, but just a few days before that release the plans had changed. David Airlie really wanted to get his Radeon driver rewrite merged sooner rather than later, and some other changes were pending that also held up the Mesa 7.5 release.
Yesterday we shared the exciting news that an OpenVG state tracker was coming quite quickly to the Gallium3D architecture for providing hardware-acceleration to this 2D vector graphics drawing API commonly used with mobile devices. This hour the OpenVG 1.0 state tracker was committed to the Mesa code-base.
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.
