Mesa News Archives
Due to some user confusion after this morning's Intel Gallium3D article regarding what Intel IGPs are actually covered by this community-alternative to Intel's official classic Mesa driver, here's an overview of all the different Gallium3D drivers.

Mesa 7.11 has been branched in preparation for its release next month. What this means is that now Mesa Git master is for Mesa 7.12, which will be the graphics code in-development until next January when it's either released as 7.12, or Mesa 8.0 should the OpenGL 3.0 support land by year's end.

Benjamin Franzke, a developer who as of the past several months has been hacking on Wayland and working to get it running over OpenWF along with making other improvements, has written a graphics buffer manager (GBM) for Mesa.

One of the Google Summer of Code projects pertaining to Mesa / X.Org is to bring-up open-source OpenCL support with the Gallium3D driver architecture. There's long been a branch of Mesa dubbed "Clover" that provides an OpenCL state tracker for the Gallium3D driver architecture, but it hasn't been usable as there's a lot of work to be finished. This GSoC project attempts to change that and there's already been a big milestone achieved.

Back in April we reported on the ambitious project by a lone, independent developer to write a GLSL IR to TGSI translator for Mesa that wouldn't involve using Mesa's crufty IR. This work would also be a stepping-stone to GLSL 1.30 support in Mesa, which is needed for OpenGL 3.0 support in this critical free software project. Today the developer is reporting that he believes this translator is ready to be merged into Mesa.

Hurra! A new Gallium3D state tracker was just released! But it's not the state tracker for OpenCL support, VDPAU or VA-API encoding/decoding, or anything else like that, but rather it's for something new: the XA State Tracker. This state tracker provides a new means of X.Org Acceleration (hence the "XA" name) and was developed by VMware.

Marek Olšák, the open-source community developer known for his contributions to Mesa / Gallium3D and to the Radeon driver in particular, has submitted a set of patches to the Mesa mailing list. This time around, these patches overhaul the Gallium3D configure/build-time options. These patches are meant to make it easier to configure Gallium3D with the Gallium3D EGL support and in automatically determining what state trackers to build. In addition, there is one prominent change in default behavior.

For those living in a very stable world, Mesa 7.10.3 is now for your building pleasure. Mesa 7.10.3 just incorporates bug-fixes, but none of the new work found in the six-months-in-development Mesa 7.11 code-base.

Finally, Mesa 7.11 is set to be released in early July. Ian Romanick of Intel has laid out plans to do a Mesa 7.10.3 point release in two weeks and then to release the proper Mesa 7.11 release in 7/11 (July of 2011).

Last September there was the release of a Direct3D 10/11 state tracker for Gallium3D. This natively implemented Microsoft's graphics API from DirectX for the latest versions 10 and 11 with Gallium3D Linux graphics drivers. While it sounded quite enticing when the code was first released, there hasn't been much activity since that point.

After releasing open-source Ivy Bridge code last month for the Linux kernel to go in Intel's DRM (Direct Rendering Manager) driver for graphics acceleration and kernel mode-setting, Intel then landed Ivy Bridge support in their X.Org driver although that isn't too interesting with most of the exciting code these days happening in the Linux kernel or Mesa library. Yesterday, however, the final big piece of the Linux support for Ivy Bridge was pushed out there: the Mesa 3D support.

Submitted to the mailing list over the weekend was a patch by Carl-Philip Haensch that implements support for Anisotropic Filtering (AF) in the ATI/AMD R600 Gallium3D driver.

What's been talked about extensively and for quite a while but not acted upon too much is ridding Mesa of Mesa IR, it's intermediate representation used internally by core Mesa and its drivers. It was also talked about as a possible summer project of replacing Mesa IR with GLSL IR. Now though an individual has begun gutting out Mesa IR and providing a direct GL Shading Language IR to TGSI (the Gallium3D IR) translator.

The open-source Mesa / Gallium3D Linux drivers not only take heat for their slow performance (in many cases, dreadfully slow) compared to the proprietary drivers, their bugs causing issues like those with KWin, and their inability to run many games/applications, but also for their very belated support in enabling support for new OpenGL extensions and versions of the GL Shading Language.

Tom Stellard, the student developer who participated in last year's Google Summer of Code to improve the R300 GLSL compiler for the open-source ATI/AMD driver, is still around and contributing to upstream Mesa. Last month he announced his new R300 register allocator being ready for wider testing. He's now announced further improvements on this GPU register allocator for Mesa.

Over the weekend there was a rant by Martin Gräßlin, the lead developer of the KWin compositing window manager for KDE, about Intel's open-source driver breaking. This is the second time in recent times that the driver has outright failed with KDE, which threatens the Intel KWin support in Ubuntu 11.04, but this time it's over the OpenGL renderer string being changed and KWin using that to determine direct rendering support. Martin has now written a very lengthy e-mail to the developers of Mesa.

Martin Gräßlin, the lead KDE developer of the KWin compositing window manager, usually has fairly insightful and technical blog posts. Last week he was talking about possibly moving the KDE screensaver into the KWin compositor for KDE SC 4.8 after writing the KDE view on GNOME's new compositing manager. Today he has written a new post, but this time it's about the open-source Intel Mesa driver breaking (again) for KWin.

Here's quite a pleasant surprise to wake up to this morning: OpenGL floating-point textures and render-targets support has finally been merged to mainline Mesa master! The drawn-out process that began more than a month ago is finally over.

For those preferring to live on the stable Mesa series, Ian Romanick just announced the release of Mesa 7.10.2. This release just incorporates various bug-fixes.
6 April 2011 - New Stable Update
For those that were excited last week by the French student proposing an H.264 VA-API/VDPAU state tracker for Gallium3D that in turn was revised to WebM or Theora acceleration support instead (since no current-generation GPUs have dedicated video decode engines for these formats), Emeric has firmed up his proposal.
