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.
By now many of you have likely heard that AMD is laying off around 10% of its workforce by next year in a restructuring attempt to lower its operating costs, but will their open-source and Linux efforts be hampered by this move?
The last time there was an official release of the xf86-video-ati DDX driver was back in May, but this morning Michel Dänzer has announced a new version.
Catalyst 11.10 was released yesterday for Linux and Windows platforms. Many Linux users are pleased by this driver update as can be seen from the forums, but Catalyst 11.12 is set to improve the Radeon binary blob situation even more.
On the last day of the month, AMD has released Catalyst 11.10 as their October 2011 proprietary Linux driver update.
Besides LLVM 3.0 (with an adjoining Clang 3.0 release) and GCC 4.7 coming up soon, another open-source compiler soon to be releasing is Open64 5.0, the compiler of choice by AMD.
Here's some interesting work that provides support support for multiple rings to the open-source Radeon driver for supporting multiple compute rings, a-sync DMA engines, and UVD. Yes, for video decoding, but this is just prep work and there is still no UVD specifications or code.
Earlier this month I wrote about the AMD porting their open-source Linux graphics driver to Windows EC7. Here's a few details that were learned in the past two weeks.
The classic Mesa Radeon (R300/R600) drivers that provide open-source OpenGL support on Linux instead of the Gallium3D alternatives are likely to be dropped in the coming days.
If you're using any R300/400/500 GPU with the Gallium3D R300 driver, there's some improvements coming up for you in the KDE KWin compositing window manager.
On Friday some benchmarks of the AMD FX-8150 Bulldozer on Linux were shared, thanks to an early adopter running some benchmarks under Gentoo and uploading them to OpenBenchmarking.org. But there's more to come.
The R500 texture semaphores work, the feature I wrote about and tested earlier this month, has been merged to master. This feature in the R300 Gallium3D open-source driver can provide some impressive performance improvements.
Here's the first Linux benchmarks of AMD's FX-Series Bulldozer desktop CPUs that launched on Tuesday. Specifically, it's Gentoo Linux performance results for an AMD FX-8150 Bulldozer.
