AMD has made available a new Catalyst Linux graphics driver for Linux, the Catalyst 13.2 Beta 6 release.
A rather simple patch by Vadim Girlin has led to a reported significant performance improvement within the R600 Gallium3D graphics driver.
This week was marked by quite a steady patch flow of improvements to the AMD R600 GPU LLVM back-end that's used for Radeon Gallium3D OpenCL support and is also being bettered for its handling of OpenGL.
Merged into the mainline LLVM repository on Wednesday was support for indirect addressing within AMD's R600 GPU back-end.
While AMD has yet to officially introduce their Radeon HD 8000 series, published today was the initial open-source Linux graphics driver support for handling the Radeon HD 8800 "Oland" graphics cards.
The xf86-video-ati 7.1.0 graphics driver was released today as stable with several changes.
An AMD Catalyst "13.2 Beta 3" driver has surfaced on the Internet for Linux users relying upon this binary blob for graphics acceleration on Radeon and FirePro graphics hardware.
Alan Cox, the venerable Linux kernel developer presently employed by Intel and an avid open-source enthusiast, has lashed out against the recent release of Fedora 18. Cox calls the new Fedora release, "the worst Red Hat distro I've ever seen." Alan ended up switching to Ubuntu as a result of his disastrous experience with Fedora 18.
After yesterday running some Intel Ivy Bridge graphics tests on Fedora 18 as a preview of future extensive benchmarks coming from the "Spherical Cow" release, here's some tests of the AMD Radeon R600 Gallium3D on this week-old Fedora Linux release compared to its "Beefy Miracle" predecessor from 2012.
While AMD has went months without updating their Catalyst "Legacy" Linux graphics driver for the Radeon HD 2000 through Radeon HD 4000 series graphics cards to support new X.Org Server / kernel releases and other bug-fixes, they decided today to finally put out an updated legacy driver! This updated AMD Catalyst Linux Legacy driver is tagged as version 13.1.
Catalyst 13.1 for Linux was released on Thursday as the first AMD Linux binary blob of 2013. This driver is notable since it officially supports X.Org Server 1.13.
Recently there was finally MSAA support added to the R300 Gallium3D driver. While multi-sample anti-aliasing finally made it to this open-source GPU driver that supports the old ATI R300 through R500 GPUs, benchmarks I did last week showed the R300 MSAA performance was a mess. Fortunately, Marek Olšák has made some significant performance optimizations to the R300g MSAA support.
In addition to killing the Xorg R300g state tracker target, on Sunday Marek Olšák pushed a number of other changes into the vintage "R300g" open-source graphics driver.
The open-source AMD "R600g" Gallium3D driver is slowly but surely closing in on OpenGL 3.3 support for this open-source Linux graphics driver that supports from the Radeon HD 2000 through Radeon HD 6000 GPUs.
Last year UBO and TBO for the Radeon R600 Gallium3D driver was talked about and early patches proposed, but merged on Friday was finally this support for Uniform Buffer Objects and Texture Buffer Objects. With the OpenGL UBO/TBO support, the Radeon R600g driver is now advertising GLSL 1.40 as needed for OpenGL 3.1 compliance.
Marek Olšák has implemented support for buffer copying using the CP DMA engine on Radeon HD 4000 "R700" GPUs and newer.
Catalyst A.I. is a feature built into AMD's proprietary Radeon graphics driver meant to enhance the OpenGL performance for certain games, but under Linux it's not incredibly useful.
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.
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.
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.
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.
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.
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.
