Intel SNA Acceleration Architecture Continues To Mature

A few days back when testing the Linux 3.1 kernel with Intel's Sandy Bridge hardware and then the Intel RC6 power-savings support, I also ran some updated benchmarks of SNA, the new Intel acceleration architecture available from their graphics driver.

2011 Linux Graphics Survey Results

In September the 2011 Linux Graphics Survey came to an end, but due to Oktoberfest, AMD Bulldozer Linux testing, OpenBenchmarking.org developments, and other matters, I didn't have time to look at the survey results until this weekend when getting ready for the Ubuntu Developer Summit. Here's the 2011 results looking at what Linux desktop end-users are running when it comes to graphics cards and drivers as well as their key concerns.

Linux 3.1 Enhances Sandy Bridge, Preps For Ivy Bridge

The Linux 3.1 kernel was released earlier this week and it further enhances the Intel Sandy Bridge graphics support while also prepping the open-source kernel driver for Intel's next-generation Ivy Bridge processors.

The Linux 3.1 Kernel For Older Intel Graphics

While there's many ongoing improvements for Intel's Sandy Bridge graphics and the next-generation Ivy Bridge graphics within the Linux kernel, Mesa, and xf86-video-intel (namely the SNA acceleration for the DDX), here's some benchmarks from two older Intel systems using the latest Linux 3.1 kernel to see if there are any improvements there.

AMD Ports Open-Source Linux Driver To Windows Embedded

Here's something interesting or perhaps odd: AMD has been porting the open-source Radeon Linux driver to Windows Embedded Compact 7 (WEC7) as its graphics driver.

AMD Catalyst vs. Radeon Gallium3D On Linux 3.1

If you are not taken by today's release of Ubuntu 11.10 "Oneiric Ocelot", here are some new Radeon graphics benchmarks comparing the Catalyst driver on Ubuntu 11.10 to the latest R600g driver from Mesa 7.12-devel on the soon-to-be-released Linux 3.1 kernel.

Mesa R500 Texture Semaphore Improvements

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.

Intel Mesa HiZ Performance On Sandy Bridge

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.

Gallium3D LLVMpipe Starts To Smoke

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.

This Is What Started AMD's Open-Source Strategy

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.
