There's a chance there might be a concealed backdoor within AMD's Catalyst driver, in particular within their closed-source graphics driver's OpenCL library.
Got a workload that runs badly on the r600g Radeon Gallium3D driver? You can help fix it! Optimizations are coming to the open-source Radeon Linux driver for video memory usage.
The latest Phoronix article covering AMD's latest graphics processors on Linux was earlier this article in pointing out the Radeon R9 270 is far from perfect. One of the big problems with any Radeon HD 7000 series or newer GPU is the poor 2D acceleration performance with the open-source Linux driver, but performance improvements are coming.
Yesterday saw a SteamOS Linux update that shipped a new AMD Catalyst Linux driver that reportedly worked much better for popular Steam Linux games. That driver update led Valve to officially support AMD (and Intel) graphics on SteamOS. For non-SteamOS Linux users, that new AMD driver update is available for other distributions.
A Red Hat employee working on Fedora QA has shared his experience using an AMD Radeon R9 270 graphics card under Fedora with both the open-source RadeonSI driver and the closed-source Catalyst driver. For both drivers, the AMD R9 270 is "far from perfect" on Linux.
News on AMD's "Kaveri" APU is trickling out this week from CES, besides the facts that have long been known about this "Richland" APU successor. The launch date is officially next week and there will be Linux/open-source performance testing and results to follow.
Just before Christmas was a patch by Marek Olšák that provided much better RadeonSI performance. That patch will now be merged into the Linux 3.13 kernel to be released later this month.
A new patch by Marek Olšák can boost the performance of modern AMD Radeon HD 7000+ series graphics cards on the open-source "RadeonSI" driver by multiple times.
Alex Deucher has improved the Radeon Dynamic Power Management (DPM) open-source driver support so it now works more reliably on newer AMD GPUs.
Nearly one month after the last Catalyst 13.11 beta release, the Catalyst 13.12 Linux driver has finally surfaced. For ending out the year we have this last major AMD Catalyst Linux update with no new features but there are many bug-fixes.
As shown in our recent open-source GPU driver comparison, the RadeonSI Gallium3D driver still has a long ways to mature to be more competitive against the R600g driver and the Catalyst binary driver. Fortunately, one of the major 3D performance-boosting features (HyperZ) appeared on Tuesday in mailing list patch form.
The Mesa DRM library (libdrm) was updated to version 2.4.50 today in order to address a critical bug affecting the RadeonSI driver for Radeon HD 7000 series GPUs and newer.
The RadeonSI Gallium3D driver for AMD HD 7000 series GPUs and newer is now 75% faster for the Source Engine Team Fortress 2 game thanks to a new patch-set by Marek.
While we haven't yet been able to find out whether the Radeon R9 290 series Linux performance has improved, AMD released a new Catalyst Linux graphics driver on Friday.
There's new patches by Marek Olšák for enabling 2D tiling and MSAA for the CIK Sea Islands / Hawaii graphics processors.
To complement my article about new features in GCC 4.9, a few hours ago the AMD Excavator "bdbver4" enablement I had talked about as a likely feature did successfully land.
Earlier this month there was a presentation by AMD's Tom Stellard at the LLVM Developers' Meeting about the work being done on the Radeon GPU LLVM back-end.
As part of the recent Radeon Rx 200 series and Hawaii GPU launch, AMD also unveiled Mantle as a new graphics rendering API to compete with OpenGL and Direct3D. AMD claims Mantle is easier, faster, and all-around better than OpenGL for game engines and other purposes. This week AMD has renewed their push that they want to see Mantle on Linux and other platforms.
Just a few days after AMD published open-source Radeon kernel driver code for Hawaii, their latest-generation graphics processors, the user-space support has landed for the Mesa DRM library (libdrm), the xf86-video-ati X.Org DDX driver, recognition in the AMD LLVM GPU back-end, and the Mesa RadeonSI Gallium3D driver.
While we're waiting until January for AMD to put out their Kaveri APUs that are built on their Steamroller architecture, third-generation Bulldozer, there's already GCC compiler optimizations landing for the fourth-generation Bulldozer architecture. Bdver4 Excavator APUs will succeed the bdver3 APU/CPUs in 2015.
Last week AMD released the Radeon R9 290 "Hawaii" graphics card. The R9 290 is a cut-down R9 290X and sells for just $399 USD. Here are the first Linux benchmarks of the AMD R9 290 using Ubuntu 13.10!
AMD has just published a new set of Linux kernel patches, revealing Linux support for a Cryptographic Coprocessor (AMD CCP).
The Linux 3.13 kernel that is just entering mainline development stages already has Radeon DPM and HDMI audio by default. However, now there's another Radeon DRM-Next pull and it provides support for the brand new AMD R9 290 "Hawaii" GPUs!
On Friday I shared some updated 9-card NVIDIA GeForce Linux benchmarks of Valve's Team Fortress 2. Now for some Sunday viewing are Team Fortress 2 benchmarks from nine AMD Radeon graphics cards.
The latest RadeonSI Gallium3D open-source driver benchmarks I have to share are OpenGL performance tests comparing three different Radeon HD 7000 and Radeon Rx 200 series graphics cards between the open-source Mesa 10.0 driver and Catalyst 13.11.
Just a few weeks after releasing the AMD Radeon R9 290X ultra high-end Hawaii graphics card, AMD today unveiled the R9 290. The R9 290 is one step below the 290X but will only set you back $399 USD.
AMD has made known the changes they have lined up for the Linux 3.13 kernel merge window. Among the work includes finally enabling Radeon Dynamic Power Management (DPM) for some graphics processors and also restoring HDMI audio support to be enabled by default.
With a proposed change to the xf86-video-ati X.Org DDX driver, tiling support will be enabled by default for Radeon HD 7000 "Southern Islands" hardware by default in order to boost performance.
For those with AMD Radeon HD 8000 "Sea Islands" graphics processors, the AMD GPU back-end inside LLVM now contains better support for this hardware.
AMD released the latest Linux beta today for the Catalyst 13.11 proprietary graphics driver.
