This will allow the kernel to address many of the Radeon HD-5000 series graphics cards introduced since the autumn which use this graphics chip. The driver doesn't at present make use of the acceleration features offered by these GPUs, but the drivers for older Radeon graphics hardware also started out this way, and they now do a pretty fine job.
From 2.6.34, the KMS driver for older Radeon GPUs will be able to...

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
