Gallium3D Feature Levels Plotted, Discussed

The last time we talked about Gallium3D work being done by Zack Rusin was just before the holidays when he was hacking on new geometry shader support. Zack's latest work on Gallium3D though is for defining "feature levels" that provides a table for what features can be supported by a given driver / graphics processor.

The State Of OpenGL 3.x in Mesa Core

While ATI R600 users only recently received OpenGL 2.0 hardware support within the open-source Radeon 3D stack and there is many more OpenGL extensions to be implemented just not for the ATI Mesa driver but the other DRI drivers as well, Brian Paul has published a document that lays out the current state of OpenGL 3.x within the classic Mesa core. This document lays out what core Mesa supports and not necessarily that any of the drivers are implementing the said support at this time. Granted, with Mesa not really being very performance-efficient at this time or capable of running most games, a majority of users will be waiting for the OpenGL 3.x state tracker for Gallium3D.

Gallium3D Gets New Geometry Shader Support

Zack Rusin has just shared with the Mesa development community a plethora of new code. This is not code for yet another state tracker or new hardware driver, but rather it brings new geometry shader support to the Gallium3D infrastructure. There's a new syntax now being used for geometry shaders and these patches fully implement the support, including with the TGSI components. So far the feedback on these patches are very positive and should be merged to master in the near future.

Intel i965 Gallium3D Driver To Go Mainline

VMware's Keith Whitwell has mentioned on the Mesa3D development list that he plans to merge the new Intel i965 Gallium3D driver to Mesa's master repository. At the beginning of November this new Gallium3D driver emerged and was formed within the i965g-restart branch, which continues to frequently see new work on this Gallium3D driver.

It's Your Last Chance To Test Mesa 7.7

A month and a half ago we shared that Mesa 7.7 should be a Christmas present with a release date just before the holidays. Since then we have seen release candidates for Mesa 7.7 and it's still on track to debuting next week. Intel's Ian Romanick has today announced Mesa 7.7-rc3 (along with Mesa 7.6.1-rc4 for carrying bug-fixes in the current stable branch).

The Linux Graphics Documentation That's Needed

A week ago we shared that the first of the slides and videos from VMware's recent Gallium3D workshop were now posted on the Internet. This morning some more of this content is being published, which covers the VMware SVGA driver status, a Gallium3D state tracker overview, and the status of the OpenGL ES state tracker. The content from the previous video/slides push along with today's uploads can be found here. Unfortunately we have found out that some of the videos from the Gallium3D workshop have been lost.

OpenCL Over Mesa, Gallium3D Discussion

While NVIDIA and ATI/AMD have OpenCL support within their binary drivers, the open-source Mesa / Gallium3D stack is still lacking open-source support for the Open Computing Language on Linux. But the discussion surrounding OpenCL in Gallium3D has been renewed on the mailing list today.

Mesa / Gallium3D Branch Happenings

Not only are Mesa developers -- those at VMware and within the open-source community -- busy at work on producing new state trackers (such as for OpenCL and OpenGL 3.1/3.2 support) and actual hardware drivers (or virtual drivers), but the core Gallium3D architecture and API continues to be revised as well. Over the past few days there have been some new Gallium3D branches that have come about and others that are getting ready to be merged to master, or enter the mainline Mesa code-base.

Mesa 7.7 Release Candidate 2 Is Out

Mesa 7.7 crept closer to being released last week when the first release candidate had arrived, but now we are even closer with there being a second release candidate. Intel's Ian Romanick has announced the release of Mesa 7.7 RC2 (along with Mesa 7.6.2 RC3) in hopes of still putting this release out before Christmas.

Gallium3D Workshop Videos, Slides Posted

Nearly a month ago VMware had hosted the first-ever Gallium3D Workshop at its headquarters in California for developers and users interested in this graphics driver architecture that will be predominately used on Linux. We had monitored this workshop and provided live coverage -- A Virtual Gallium3D Driver Coming For VMware and The State Of Gallium3D, Its Future, Etc -- but beyond that not much information was released about the conference. Today, however, the slides and video recordings from this Gallium3D Workshop are finally coming out.

VMware Releases Its New Gallium3D Driver

Last Friday during the Gallium3D workshop we learned that the Tungsten Graphics developers that were bought out by VMware have been working on a virtual Gallium3D driver that would be used by guest operating systems running within VMware's virtualization platform. This is especially interesting considering that it will allow virtualized guests to have accelerated access to X11, OpenGL, OpenCL, X-Video, XvMC, and all sorts of other possibilities that's just limited by what's supported by the available state trackers.

The State Of Gallium3D, Its Future, Etc

VMware hosted a Gallium3D workshop today at its headquarters in California (and via teleconference too) where the former Tungsten Graphics developers talked about all that they have been working on with Gallium3D, the current state of this graphics driver architecture, and what's to come. The biggest news coming out of this workshop is word that a virtual Gallium3D driver is coming, which will allow Gallium3D to run within a virtualized environment. It's looking like there will be this Gallium3D driver that can run within a VMware guest virtual machine and then take advantage of the state trackers on the host machine whether it be providing hardware-acceleration for OpenGL, OpenGL ES, OpenVG, OpenCL, etc. We're also thinking now that it's even more likely a Direct3D 9/10 state tracker will be made available too.

Overhauling Mesa's GLSL Compiler Performance

We like hearing about performance improvements for Linux and also Linux graphics in general, but when there's something about performance improvements for Linux graphics, it certainly gets us excited and garners our interest. This time we get to report on work being done to Mesa's GLSL compiler, which is now running drastically faster in a branch of Mesa that will be published in about a week.

Mesa Comes To Android-based x86 Netbooks

If you pay attention to the Mesa3D development mailing list at all you will have noticed quite a number of messages lately from Chia-I Wu, who has been pushing a good number of patches lately. Largely his work has pertained to OpenGL ES support for mobile devices, but his intentions are now known. Chia-I Wu is bringing Mesa (Gallium3D inclusive) to Android. In particular, Chia-I is focusing on running Mesa under Android on Intel-powered netbooks.

ATI R300 Gallium3D DRI Support Is "Done"

A month ago we shared that the Gallium3D driver for the ATI R300/400/500 graphics cards (up through the Radeon X1000 series) was mostly done. Now today, the key author of the R300 Gallium3D driver, Corbin Simpson, has updated the status wiki to reflect the latest changes. The key change? The DRI state tracker report is no longer "mostly" implemented, but now it's "done" according to Corbin.

The State of State Trackers In Gallium3D

With all of the talk earlier this week regarding the Poulsbo Gallium3D driver and its performance improvements along with the restarted efforts on the Intel 965 Gallium3D driver and then word that Mesa 7.7 may be out by Christmas, it's likely that many are wondering about the current state of the various Gallium3D state trackers that we have been talking about for the past months. Well, here's a few observations on the different state trackers at least where they are at in Git.

Mesa 7.7 May Be A Christmas Present

The Mesa 3D graphics library on Linux has been moving along at a brisk pace lately with a frequent stream of new releases as many features arrive like new Gallium3D state trackers, maturing of new hardware support (particularly with the ATI Radeon graphics), and new OpenGL extension support. Mesa 7.6 was released in September, but now Intel's lead OpenGL contributor, Ian Romanick, has proposed a release schedule for Mesa 7.7.

DRM Development Documentation (TTM, GEM, KMS, etc)

One of the common complaints that arise from hopeful X.Org / Mesa developers or those aspiring to contribute to this critical free software area is that there's not enough documentation that is up-to-date and covers the internals of the X Server, Mesa, DDX drivers, etc. Well, for those looking to get into any Direct Rendering Manager (DRM) work, a heap of new documentation is available. Intel's Jesse Barnes has invested a great deal of time in updating (well, creating) the DRM developer documentation.

Assembly Shader Extension For Mesa Drafted

Back during the X Developers' Conference last month, one of the sessions was on GL shaders for Shader Model 3/4. This talk led by Ian Romanick called for advanced assembly shader extensions for Mesa, which would greatly benefit some middle-ware projects like Wine and Cedega with Mesa's current state and not having a bolstered GLSL implementation. None of the current OpenGL extensions are suitable for this due to some of the extensions being designed for use on specific hardware, rather than being ideal for use across all Mesa drivers/hardware, and other extensions not satisfying the needs Ian and other developers want. Long story short, Ian has written a new OpenGL extension as a result: GL_MESA_gpu_program3.

ATI R300-R500 Gallium3D Driver Is "Mostly" Done

It has been a while since talking specifically about ATI's Gallium3D driver, but there is some good news coming out now for the driver that supports the ATI R300 through R500 (Radeon X1000) series hardware. Corbin Simpson, the developer that has largely been working on porting the 3D work from the classic Mesa driver to Gallium3D, has updated the Radeon Feature Matrix page on the X.Org Wiki last night.

Linux Foundation To Take Stab At 3D Patent Issue

This week at the X Developers' Conference there was a talk surrounding OpenGL 3.x and its lack of complete support within the latest Mesa code. While development manpower can end up be limiting, there are also some patent / legal issues surrounding this with regard to some parts of core OpenGL being covered by such inhibitive patents. This was explained here along with some of the possible ways to circumvent the issue.

Patents May Cause Issues For OpenGL 3 In Mesa

While work on OpenGL 3.x support in Mesa has been very slow, many have been looking forward to the day when Gallium3D hardware drivers provide fast acceleration and a OpenGL 3 state tracker to provide this support to all Gallium3D users. Intel though has also been wanting to bring some OpenGL 3 support to the classic Mesa stack. However, at XDC2009, Intel's Ian Romanick has expressed some issues with patents that could inhibit the support.

XvMC Work Moved To X.Org State Tracker

At the beginning of this month we shared news about X-Video and EXA coming to Gallium3D through a new X.Org State Tracker being written by Zack Rusin. While Gallium3D was designed for providing 3D acceleration of sorts (OpenGL, OpenVG, OpenGL ES, etc), with the latest graphics processors using the 3D engine for even providing 2D EXA acceleration, Zack spanned this support to include EXA and then X-Video. Just a few days ago the real X-Video work began in this state tracker. Now though, the support to bring XvMC to the Gallium3D has moved to this X.Org state tracker too.

Work On X-Video In Gallium3D Is Underway

Earlier this month we shared that X-Video and EXA support were coming to Gallium3D in the form of a state tracker to accelerate these X.Org APIs across any Gallium3D driver. At the time of that earlier article, the EXA 2D support was being partially implemented but the X-Video support was still left to be accomplished. Well, as of this afternoon, Zack Rusin has started pushing out code to the X.Org state tracker in Mesa that is adding the X-Video support.

Gallium3D's Softpipe Driver Now Runs Faster

Keith Whitwell has gone ahead today and merged the softpipe-opt branch of Mesa into the master Mesa branch, which will eventually work its way into Mesa 7.7. The softpipe-opt branch brings performance optimizations to the "softpipe" driver of Gallium3D. The softpipe driver is a pure software implementation of Gallium3D for use in testing and for where a hardware driver has not implemented full support. With the merging of this optimized driver, the performance should be comparable to that of the Mesa Software Rasterizer with the traditional OpenGL stack.
