To be published on Thursday and Friday of this week is the annual "year in review" articles for the AMD Catalyst and NVIDIA Linux graphics drivers. While those articles are looking at the OpenGL performance for all driver releases made in the past year, some OpenCL benchmarks were also conducted.
David Airlie recently published UBO and TBO patches for Gallium3D that allowed the Softpipe driver to work with the OpenGL Uniform Buffer Object and Texture Buffer Object features. Airlie has now worked on AMD's R600 Gallium3D driver to support these OpenGL 3.x features as part of GLSL 1.40 support.
While there was already one round of driver changes for the AMD Radeon DRM kernel driver to be found in the Linux 3.8 kernel, followed by a second pull days later that landed a-synchronous DMA engine support, there's now a third set of changes targeting the Radeon driver in this next kernel release.
It was just days ago that the R300 Gallium3D driver got HyperZ support fixed-up and was finally enabled by default for bettering the OpenGL gaming performance with the open-source Linux graphics driver. Now it looks like the newer R600g driver is getting into shape for properly handling ATI/AMD HyperZ.
After being in development for the past year, AMD's Radeon R600 LLVM back-end has been merged into the upstream LLVM code-base.
AMD released the Catalyst 12.12 Linux graphics driver for those still reliant upon their binary blob for Radeon/FirePro graphics card support.
After the benchmarks of the Radeon Gallium3D sub-allocator that in some tests yields more than a 25% performance boost, initial testing was done of the new AMD a-sync DMA engine support for the open-source Radeon driver.
With a patch sent to the Mesa development list on Monday, Marek Olšák has made another significant performance improvement to the commonly used R600 Gallium3D driver for AMD Radeon graphics cards.
AMD has released updates to their multi-platform APP SDK for Accelerated Parallel Processing as well as to CodeXL, their closed-source tool for analyzing OpenCL code.
A second update to the Radeon DRM driver has been released that will be pulled into the Linux 3.8 kernel. This second Direct Render Manager update for the Radeon kernel driver provides new code from AMD that was kept internally for months but is now permitted for open-sourcing.
Alex Deucher of AMD emailed in a pull request on Friday afternoon for the Radeon graphics driver that will end up as part of the DRM pull for the Linux 3.8 kernel.
AMD has released yet another beta Linux beta driver for the Catalyst 12.11 series.
Marek Olšák has fixed up the HyperZ support within the R300 Gallium3D driver so that it's working properly for more applications. R300 HyperZ is finally in a state where he may be looking to enable the feature by default.
While no future generation Geode processors are coming out of AMD, the open-source community still continues to maintain the Geode X.Org graphics driver. Released on Sunday was the xf86-video-geode 2.11.14 driver.
It's been nearly one year since AMD began rolling out their Radeon HD 7000 "Southern Islands" graphics cards and while there is AMD Catalyst Linux driver support, the open-source driver support for this latest-generation AMD graphics hardware is still a disappointing mess.
Red Hat has announced that they've initiated a new project to bootstrap Fedora on the ARMv8 64-bit low-power architecture.
Weeks after NVIDIA released a new Linux driver to massively improve its OpenGL performance in large part to make the Source Engine and Valve's games run better on Linux, AMD is out with a similar Catalyst update. The latest Catalyst Linux beta is said to bring "significant performance improvements" for Left 4 Dead 2.
Many Linux users have been mad over AMD closing down its Operating System Research Center resulting in many AMD Linux open-source developers losing their jobs. Last week I wrote that ultimately it shouldn't be too worrisome for Linux users wanting to use AMD processors and chipsets on Linux and this still looks to be the case.
While many Linux users are rightfully quite mad over AMD laying off many Linux kernel developers and shutting down their Operating System Research Center, not all hope is lost for future AMD CPU products being well supported under Linux.
AMD has indeed shutdown its Dresden-based Operating System Research Center (OSRC) in the latest round of cost-cutting efforts.
Alex Deucher announced the release of the xf86-video-ati 7.0.0 driver this morning, which is the first open-source ATI Linux graphics driver release that is strictly KMS-only.
There's been another improvement to Mesa with the Radeon Gallium3D R600 driver by Marek Olšák that can improve the OpenGL performance in certain situations for this open-source AMD Linux driver while also conserving memory usage.
At the beginning of the week I reported that AMD got rid of at least three of their Linux kernel developers. It's becoming more clear though that it's not only three long-time Linux kernel developers they have let go.
For those pulling down the Git master of the xf86-video-ati X.Org graphics driver this week, 2D color tiling is finally enabled by default for Radeon HD 2000/3000/4000/5000/6000 series graphics cards, from R6xx through the "Cayman" GPUs.
At least three Linux kernel developers are no longer employed by AMD.
Here's another series of AMD FX-8350 "Vishera" Linux benchmarks to complement the many Vishera Linux benchmarks published on Phoronix since the debut of the FX-8350 processor on Tuesday.
One of the latest possible Linux power-related regressions I've heard about is that AMD Cool 'n' Quiet may no longer be functioning too well on Linux-based systems.
AMD Catalyst 12.10 for Linux was only officially released two days ago, but already there's a Catalyst 12.11 beta for Tux.
For those wanting more benchmarks of the AMD FX-8350 Eight-Core "Vishera" processor, here's some additional Ubuntu 12.10 results.
AMD's Catalyst 12.10 Linux graphics driver was released today.
