While AMD is behind the ball on supporting Radeon HD 7000 series hardware, they're finally beginning to catch-up with supporting OpenCL for GPGPU computing on their open-source Linux graphics driver with Gallium3D.
Yesterday AMD officially launched the Radeon HD 7800 "Pitcairn" series as the latest hardware in their Southern Islands family to reside between the Radeon HD 7700 series and their flagship Radeon HD 7900 cards. Unfortunately, the open-source support for these latest AMD GPUs remains unavailable.
While most Linux enthusiasts know by now that there still isn't open-source Radeon HD 7000 series support from AMD under Linux, the Catalyst situation isn't so clear. While they've been committed to launch-day Catalyst hardware enablement under Windows and Linux, for the penguin OS that doesn't seem to always be the case for the HD 7000 series.
Christian König of AMD has shared his plans for completing work on the VDPAU state tracker for Gallium3D. This Gallium3D state tracker allows for NVIDIA VDPAU video acceleration using GPU shaders on open-source hardware drivers such as Radeon and Nouveau.
For those AMD Catalyst users that were concerned by the recent statements of Martin Gräßlin that KWin will likely end up dropping their GL1 renderer, which would eliminate vintage GPU hardware support as well as Catalyst driver support, fear not.
Where oh where is the open-source support for the "Southern Islands" GPUs, a.k.a. the AMD Radeon HD 7000 series? It's been over two months since the first hardware launched and there still is no open-source Linux driver support available.
AMD today launched the Radeon HD 7570/7770 graphics cards as the latest GPUs built on the GCN architecture. Unfortunately there still is not any open-source support for the Radeon HD 7000 series hardware nor has AMD sent out any review samples to Phoronix. But there is some other Catalyst Linux news to share.
Coming up in the next few days will be benchmarks of Mesa 8.0 with Morphological Anti-Aliasing (a.k.a. MLAA) plus some other imaging-oriented work/announcements to come in the near future. With that said, this weekend prior to leaving for Munich I ran some tests of the Radeon Gallium3D and Catalyst drivers when comparing the image quality.
Now that the Radeon R600 tiling patches are done, Jerome Glisse has moved to updating the out-of-tree Hierarchical Z patches for the Radeon HD 2000 through 6000 series.
Jerome Glisse, the Red Hat developer commonly working on the open-source Radeon graphics driver, has announced that he believes the R600 Gallium3D tiling support is complete.
AMD released the Radeon HD 7950 today as the second "Southern Islands" graphics card following the release of the Radeon HD 7970 one month ago, but how is the Linux support for the new AMD Radeon GPUs?
AMD has unleashed the first Catalyst Linux binary driver update of 2012, but does Catalyst 12.1 bring anything interesting or just more breakage?
Minutes after publishing the Mesa 8.0 Radeon Gallium3D benchmarks against Catalyst, first-stage patches were posted for proper 2D color tiling support for modern Radeon hardware from, which can result in double-digit performance gains.
While we still haven't been able to deliver any Radeon HD 7000 series Linux benchmarks, we do know what are AMD's three priority projects right now for their open-source Radeon Linux driver stack.
AMD launched the Radeon HD 7970 graphics card yesterday as the first built upon their GCN (Graphics Core Next) architecture. Besides the initial Phoronix coverage of this first "Southern Islands" product, there's some new open-source Linux driver information today.
You've may have heard or seen that AMD introduced the Radeon HD 7970 graphics card this morning as their first product built in their "Southern Islands" family and is based on their new GPU architecture, but how well does it work under Linux for the open-source and closed-source AMD Catalyst Linux drivers?
The XBMC multimedia project has implemented AMD's XvBA interface directly for providing video hardware acceleration for Radeon and Fusion graphics processors.
A new version of AMD's Catalyst Linux graphics driver is now available.
On Friday AMD released an LLVM back-end for its R600 Gallium3D Linux driver. The LLVM driver back-end was based upon the AMD IL LLVM back-end for OpenCL, which AMD has now separately announced to the LLVM developers as a new source-code drop.
Before calling it a week, Tom Stellard at AMD published a Git branch that offers up an LLVM shader back-end for the AMD R600 Gallium3D driver. This is one of the steps in bringing Compute/OpenCL support to the open-source AMD Radeon Linux graphics drivers.
There's another update to the recent AMD Driver Support State For Radeon HD 7000 Series, Trinity article. The Radeon HD 7000 series will in fact bring a new Gallium3D Linux driver.
While AMD still hasn't published Radeon HDMI audio patches for their open-source Linux driver to enable the audio support on their Radeon HD 5000 series and newer, the reverse-engineered community patches have quickly evolved.
A few weeks ago I began talking about the AMD Radeon HD 7000 series driver support, but this week there is some new information to share about the hardware enablement for the next-generation of Radeon graphics processors as well as next year's AMD Trinity APUs.
David Airlie has made a number of commits to Mesa today that make some modest enhancements to the vintage Radeon R100/R200 classic OpenGL driver.
It was just yesterday that I was writing about AMD still not having any new HDMI audio support code available to the public for the Radeon HD 5000 series and newer. The hold-up on this HDMI audio code for the open-source Radeon driver has been due to the patches failing to clear AMD's legal review multiple times. Well, leave it up the community, and now this morning there's some Evergreen patches for this support.
For those that haven't noticed, the open-source Radeon Linux graphics driver still lacks HDMI audio support for the Radeon HD 5000 "Evergreen" series and newer graphics processors. This has been sought after for many months, but even with the Linux 3.2 kernel, AMD still doesn't have to go-ahead with the open-source audio support.
AMD's interested in driving the use of OpenCL within the open-source world, and they're willing to pay for it. One of their new contracts is to have more of the OpenCL work for GIMP/GEGL on the Open Computing Language.
For those wondering what AMD's open-source Linux graphics driver developers are likely working on...
After a belated Catalyst 11.10 release, this month's proprietary Catalyst Linux driver for ATI/AMD Radeon and FirePro graphics cards is now available. The Catalyst 11.11 driver does bring some critical changes.
In recent weeks there have been a lot of AMD Linux benchmarks of the latest-generation Bulldozer processor, namely the eight-core FX-8150. The latest unique look at the first-generation Bulldozer CPU under Linux is the KVM virtualization performance.
