Fedora 19 is the first tier-one Linux distribution shipping with decent "out of the box" support for the AMD Radeon HD 7000 "Southern Islands" series graphics cards with the out-of-the-box Linux graphics driver and Gallium3D-based acceleration.
For AMD Radeon customers using the open-source Linux graphics driver, the Linux 3.11 kernel is going to be mega exciting! Alex Deucher of AMD posted a set of 165 kernel patches today. Most notably, there's finally Dynamic Power Management (DPM) support for R600 GPUs up through Southern Islands hardware! Yes, there's finally dynamic power management in the open-source driver. Additionally, there's initial support for AMD "Sea Islands" hardware and there's also ASPM (Active State Power Management) support.
For those curious how AMD's Bulldozer CPUs are performing with this week's release of LLVM 3.3, here are some benchmarks of LLVM/Clang 3.3 along with some early benchmarks of the latest Clang 3.4 development code from the AMD FX-8150 Eight-Core CPU.
It's been a while since last talking about the project to bring the Linux driver for AMD Radeon KMS to FreeBSD. The project is still going forth for expanding FreeBSD kernel mode-setting, but there hasn't been too much progress as of late.
