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.
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!
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.
AMD published this month new programming guides and register documentations for the 3D/Compute engines on their Evergreen, Northern Islands, Southern Islands, and Sea Islands graphics processors.
Tom Stellard of AMD has published a new post enabling the R600/SI LLVM GPU back-end to handle Radeon HD 8000 "Sea Islands" GPGPU/Compute support.
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 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.
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.
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 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.
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 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.
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.
Nearly three weeks after Catalyst 13.8 Beta for Linux, AMD has now released the second Linux graphics driver beta of the month.
