Tom Stellard, the former Google Summer of Code student who worked on ATI R300 GLSL compiler improvements and a new register allocator, has been looking into the area of Radeon OpenCL support while now being employed by AMD. However, Tom is working on other open-source Radeon work too. Recently he made improvements to the R300g driver's instruction scheduler to make better use of the texture semaphore.

While there are still several days left of this year's Oktoberfest, to take a short break this morning from benchmarking the wonderful beer, food, and Bavarian females, here are benchmarks of the new Intel HiZ Linux support. Just a few days ago a new, nearly ready patch-set was published for implementing hierarchical Z support within Intel's Mesa DRI driver.

While it's rare for a few days to pass at Phoronix without pulling the latest development code for Mesa / Gallium3D and the Linux kernel DRM in order to run updated Radeon, Intel, and Nouveau Linux graphics benchmarks, LLVMpipe isn't benchmarked as commonly. LLVMpipe is the new CPU-based software acceleration method for the Gallium3D that leverages the Low-Level Virtual Machine to provide better performance than the classic Mesa software rasterizer or Softpipe. Fortunately, upon running a brand new set of tests, the results show a bit more promise but there is still much work ahead.

While AMD's open-source strategy was announced on Phoronix on 7 September 2007, it was on 17 September of the same year that the Novell/SUSE developers did their first public release of their xf86-video-radeonhd driver. This was the X.Org driver created by the Novell Linux engineers in months prior for R500 and R600 GPUs. Here is some special reading -- a letter that was volleyed from Novell to AMD that kicked off this entire process -- to celebrate what would have been the fourth birthday of this open-source Linux driver.

After the benchmarks a few days back of Intel Sandy Bridge Acceleration On Non-SNB Hardware, Chris Wilson of Intel who has been responsible for much of the "Sandy Bridge New Acceleration" work requested more tests, but this time to see the effect that the compositing window manager has on this new acceleration architecture. As a result, here is some quick tests of Intel's Sandy Bridge graphics under the Unity, Unity 2D, and GNOME Shell desktops.

Last week benchmarks were published of Intel's New Sandy Bridge Acceleration architecture (SNA) that showed several performance improvements for 2D and 3D, but the new acceleration architecture still wasn't mature with a few regressions compared to the normal UXA back-end. While the focus of this SNA support is on speeding up operations for Sandy Bridge (SNB) and forthcoming Ivy Bridge (IVB) hardware, SNA is supported for older Intel graphics processors too. Here are some benchmarks of the Sandy Bridge New Acceleration architecture when using the Ironlake and Gen3 back-ends.

In preparing for XDC2011 Chicago, the X.Org developers' summit that begins in just ten days that I have organized, the schedule is being worked out at the moment. One of the items that is set to be talked about at XDC2011 during the Nouveau driver discussion is TimeGraph. This is an open-source GPU command scheduler that sounds fairly interesting.

In early June there was the introduction of the Sandy Bridge New Acceleration Architecture by Intel that dramatically excelled the 2D and 3D performance of their processor graphics on their Sandy Bridge hardware along with previous-generation IGPs. Here is a look at how the SNA acceleration architecture is performing today.

A month ago we looked at the Radeon HD 6550D graphics performance from the AMD Fusion A8-3850 (a new "Llano" APU) under Linux when using the Catalyst driver. However, bugs at the time had barred a comparison of the Llano graphics under Linux with the open-source Mesa/Gallium3D driver. Fortunately, we now have a working open-source Radeon driver configuration to deliver these comparative AMD Llano Linux OpenGL benchmarks.

While the Linux power consumption may be up on recent kernels depending upon your hardware configuration, there's a few known but not too commonly used tweaks for reducing your system power consumption and extending your battery life when using Intel integrated graphics on your favorite Linux distribution.
