After Dropping Old GPU Drivers, Ian Axes More Mesa Code

One week ago Ian Romanick called for old Mesa drivers to be removed from the mainline tree so that Mesa can move forward and be cleaned up to better the support for modern GPUs. These old Mesa drivers were DRI1-only, rarely ever received new work, and were largely for vintage graphics processors that most people haven't touched in years (e.g. the 3Dfx Voodoo days). With most developers approving this move, the old Mesa graphics drivers were removed. Ian Romanick has now moved further along with a slew of new patches to delete more code from Mesa.

A 40-Way Gallium3D Graphics Card Comparison

If you're not following me on Twitter, you're missing out on news and some very interesting photos that were posted this weekend. No, it's not of the latest beer, but of a feast of graphics cards. A 40-way comparison of NVIDIA/AMD graphics cards on Linux with the open-source Mesa/Gallium3D drivers versus their proprietary brethren is being carried out for publishing in September.

The VP8 State Tracker That Was Born This Summer

From this year's Google Summer of Code we know that morphological anti-aliasing (MLAA) for Gallium3D was a great success ready to be merged, there was good progress with the OpenCL Gallium3D state tracker, and the remote Wayland Display Server didn't make it too far. But was it a success for the VP8 state tracker for accelerating Google's video codec in Gallium3D with VDPAU? Here's a status update.

Mesa Kills Old Hardware Support: No More 3dfx Voodoo

The death sentence to legacy Mesa drivers was carried out over the night. All DRI1 drivers have been removed from the Mesa tree along with support for BeOS and other old code, in an effort to remove drivers that receive little maintenance and are just causing a greater burden in re-factoring core Mesa code for the modern drivers. This means though that the Linux desktop loses its support for hardware like VIA Unichrome and 3dfx Voodoo graphics cards.

Android Support Merged Into Mesa / Gallium3D

It's now possible to build and run mainline Mesa releases on Google's Android platform. While this doesn't make too much sense to use Mesa on Android for mobile ARM devices due to the lack of open-source Mesa / Gallium3D graphics drivers in this area, this support opens up new possibilities for running the Android operating system on x86 netbooks and tablets.

Legacy Mesa Drivers Receive Their Death Sentence

Last year at XDS 2010 Toulouse there was a discussion about killing old X.Org / Mesa drivers with fire. In particular, dropping all the old drivers that go un-maintained and have little in the way of users and modern functionality. Last year they decided to not really do much about it since these drivers cause little maintenance burden, but the topic has been brought up again and it sounds like these crusty old Linux drivers will finally receive their death sentence.

Gallium3D OpenCL GSoC Near-Final Status Update

Google's 2011 Summer of Code is coming to an end with today being one of the soft deadlines for the student developers to finish up work on their summer projects. Of the Mesa / GSoC summer projects this year, I mentioned the MLAA support for Gallium3D was a success with the post-processing infrastructure and morphological anti-aliasing support seeking mainline inclusion into Mesa. Here's a status update on how the Gallium3D OpenCL support has come over the summer.

Gallium3D Post-Processing, MLAA Nearly Ready

One of the projects being worked on via X.Org / Mesa with the 2011 Google Summer of Code is morphological anti-aliasing (MLAA) support for Gallium3D / Mesa. Back in July there was MLAA code ready to be tested, but now the student developer behind this code, Lauri Kasanen, has published patches that add the post-processing infrastructure to Gallium3D. The work may soon be ready to be merged to master.

What Mesa Has Left With OpenGL 3, OpenGL 4

With the release this week of the OpenGL 4.2 specification (and accompanying GL Shading Language 4.20 revision), the TODO list for the open-source Mesa developers just got a bit longer. Mesa / Gallium3D still lacks full support for OpenGL 3.0 and all of the revisions since that 2008 specification release.

Mesa Developers Still Fear Patent Wrath With S2TC

One month ago I mentioned there was a possible workaround for the S3TC patent situation. The possible S3TC workaround was S2TC, which is a simpler implementation of texture compression than the patented S3 Texture Compression algorithms, and comes gratis from the developers of the Xonotic game. However, Mesa developers still aren't thrilled about this possible solution.

VP8 Gallium3D Support In Mesa Is Being Worked On

Besides pipe-video landing in Mesa, there's some more good news to report when it comes to accelerated video playback over Mesa/Gallium3D. There's a VP8 state tracker for this Google format that's actively being developed.

Mesa Gallium3D Pipe-Video Has Landed

As expected, Christian König has pushed the Gallium3D pipe-video work into the mainline Mesa repository, which will be one of the big features to be introduced in Mesa 7.12/8.0 release, not the forthcoming Mesa 7.11.

GLSL-To-TGSI For Mesa Is Still Not Merged

Last month it was announced that the GLSL IR to TGSI translator for Mesa that avoids the use of the inefficient and old Mesa IR was ready to be merged. A month later, the code for this core Mesa improvement hasn't been pulled.

Gallium3D Pipe-Video To Be Merged To Mesa Master

The next release of Mesa, which will be released as either Mesa 7.12 or Mesa 8.0 (assuming OpenGL 3.0 compliance) next January, is already beginning to receive some exciting features. Mesa 7.11 isn't being released until the end of this month, but the changes taking place in Git master are quite enticing for those wishing to live on the bleeding-edge of open-source Linux graphics drivers.

Mesa Gets OpenGL 3.0 Floating-Point Depth Buffers

Yet again Marek Olšák has made another great improvement to Mesa. Recently this independent developer has been working quite a lot in implementing OpenGL 3.0 support for the open-source Mesa stack. Ending out this weekend, he now has working OGL3 floating-point depth buffers per the GL_ARB_depth_buffer_float extension.

Floating-Point Depth Buffers For Mesa

There's another item on the TODO list for Mesa's OpenGL 3.0 support to scratch off. Marek Olšák has been viciously finishing up bits of OpenGL 3.0 support (along with his always-excellent work to the Radeon Gallium3D drivers) and has now produced a set of 13 patches that provide floating-point depth buffers.

Gallium3D Clover Can Now Execute OpenCL Native Kernels

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.

GLSL IR To TGSI Translator Ready To Be Merged Into Mesa

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.

VMware Releases The XA Gallium3D State Tracker

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.
