The AMD Catalyst (fglrx) graphics driver is generally notorious in having belated support for new Linux kernel and X.Org Server releases while NVIDIA is usually very quick in supporting development kernels / xorg-servers. This time around for the Linux 3.12 kernel, the mainline Catalyst beta already supports the yet-to-be-out kernel while NVIDIA does not have this compatibility.
Complementing the article earlier today why Radeon graphics are faster on Linux 3.12, here's some benchmarks now showing the open-source Radeon results when using the CPUfreq performance governor on Linux 3.12 with the Core i7 4770K Haswell.
Earlier today in The AMD Radeon Performance Is Incredible On Linux 3.12, ten different AMD Radeon graphics cards were tested to complement the original Linux 3.12 Brings Big AMD Radeon Improvements article from Saturday. In changing things up from looking at the discrete AMD GPU performance, here are some benchmarks of an AMD Fusion E-350 APU with the Linux 3.11 and 3.12 kernels.
AMD released their first beta of the Catalyst 13.11 Linux graphics driver today. Details are scarce as to the changes in this new Catalyst Linux Beta, but it brings support for AMD's just-released hardware.
For some AMD Radeon graphics cards when using the Catalyst driver, the HDMI audio support isn't enabled unless using the simple DVI to HDMI adapter included with the graphics card itself... If you use another DVI-to-HDMI adapter, it won't work with Catalyst. AMD intentionally implemented checks within their closed-source driver to prevent other adapters from being used, even though they will work just fine.
While there's still quite a number of weeks to go until seeing the Linux 3.13 kernel enter the development spotlight, the open-source Radeon HDMI audio support will hopefully be in great shape for those that have wanted features like HD audio pass-through for DTS-HD and Dolby TrueHD.
While Intel has their highly-tuned "SNA" acceleration architecture for delivering maximum 2D performance, it turns out the OpenGL-based GLAMOR acceleration architecture for the open-source Radeon driver may be better than the xf86-video-ati driver's own EXA implementation.
While AMD has published open-source Radeon GPU driver code for modern graphics processors up through the latest Sea Islands parts, they have fallen behind on publishing 3D GPU programming specifications and programming guides for the more modern hardware. Fortunately, they have now caught up.
A few weeks ago AMD began releasing technical documentation on the HDA audio portion of their Radeon GPUs. Yesterday AMD published the second version of their HDA programming documentation.
Just before the end of the month, AMD released the Catalyst 13.10 Beta Linux graphics driver.
Earlier this week I wrote about X-Video support coming to GLAMOR and now it's been implemented by the xf86-video-ati Radeon driver.
This week at AMD's Hawaii event where they announced their new high-end graphics processors, they also announced Mantle. AMD's Mantle is a new graphics API that looks to take on OpenGL and Microsoft's Direct3D as a new high-performance graphics rendering API.
AMD Radeon KMS support landed into FreeBSD 10 last month, but the developer -- who has been working on this code in part by financing from the FreeBSD Foundation -- is continuing to make improvements to the open-source AMD graphics code ported to FreeBSD from Linux.
Tom Stellard of AMD shared a status update on the current support level and capabilities of the open-source OpenCL implementation by Gallium3D's Clover state tracker and the open-source AMD Radeon Linux graphics driver.
AMD announced today the Radeon R9 290X graphics card as their new ultra high-end product.
AMD has finally published NDA-free public programming documentation concerning the HDA audio support on Radeon GPUs.
Open-source developers are adding run-time power management support to the open-source Radeon DRM graphics driver for supporting ATI/AMD PowerXpress laptops.
AMD has officially released Catalyst 13.9 for Linux today.
AMD developers working on the Radeon X.Org driver (xf86-video-ati) have enabled GLAMOR acceleration support by default at build time.
With Git activity this evening, StreamOut / OpenGL Transform Feedback is now enabled for the AMD "RadeonSI" Gallium3D driver for the Radeon HD 7000 and 8000 series graphics processors.
The AMD Radeon HD 7000 "Southern Islands" graphics cards launched in December of 2011, but even nearly two years later while there has been open-source Linux graphics driver code available for months, Ubuntu Linux still doesn't have out-of-the-box support for these new AMD Radeon graphics cards.
After the kernel-side AMD Berlin APU support was merged for the Linux 3.12 while the user-space Mesa Gallium3D and Radeon X.Org driver support was just merged on Friday evening for this first HSA APU.
The AMD "RadeonSI" Gallium3D driver for Radeon HD 7000/8000 series hardware support by the open-source Linux graphics driver is about to support OpenGL 3.0. While the hardware is capable of OpenGL 4.4, the open-source RadeonSI driver has only advertised OpenGL 2.1 compliance.
The Linux 3.11 kernel hasn't even been released yet but the Radeon DRM driver changes for the Linux 3.12 kernel are already lined up and waiting to be pulled into the drm-next tree.
It was anticipated R600 SB shader optimizations might be enabled by default for this Radeon Gallium3D driver and now they have been for Mesa 9.3/Mesa 10.0.
While Marek Olšák is most known for his improvements to the R600 Gallium3D driver, the new open-source AMD employee's latest code activity has been on the RadeonSI Gallium3D driver.
After many months of development, the ported open-source AMD Radeon DRM/KMS driver from the Linux kernel has been merged into FreeBSD trunk. This AMD kernel graphics driver now provides modern Radeon/FirePro graphics support for BSD users with FreeBSD 10.0 but might be backported to FreeBSD 9.
The AMD Radeon "R300" Gallium3D driver has finally enabled MSAA anti-aliasing support for the very old ATI R300 and R400 class graphics processors.
Some months ago there was talk of doing LLVM point releases and it looks like this might actually happen now for the LLVM 3.3 series thanks in part to AMD.
Vadim Girlin has proposed a Mesa patch that would enable the "R600 SB" shader optimizations to be enabled by default for the Radeon Gallium3D driver. This R600 SB support has already become very popular with Linux graphics enthusiasts for its performance-enhancing abilities.
