As reported earlier this week, HiZ support is now ready for Intel Sandy Bridge graphics under Linux with the Mesa driver. A set of more than three dozen patches were published that finalize this support for Sandy Bridge (Gen6) while the Ivy Bridge (Gen7) support is almost there but there are some performance regressions still being worked out by Intel's OSTC developers.

Back in September I provided the most comprehensive AMD Radeon Linux graphics comparison that took 28 graphics cards from all supported ATI/AMD Radeon product families and tested them under Linux using the latest Catalyst driver as well as the open-source Mesa/Gallium3D driver. In this article is a similar comparison on the NVIDIA side as I take most of the GeForce graphics cards at my disposal and try them under the NVIDIA binary Linux driver and the community-developed open-source "Nouveau" driver. Not only is the OpenGL performance looked at for multiple generations of NVIDIA hardware, but the thermal and power consumption is compared too. In certain OpenGL workloads, the open-source Linux driver is now faster than NVIDIA's own driver for select graphics cards in a fair comparison, but overall the NVIDIA blob still reigns supreme.

While KVM may be very fast for Linux virtualization, one of the areas where VMware and VirtualBox are superior is when it comes to the ability to provide hardware-accelerated 2D/3D support to guest virtual machines that ultimately is passed onto the host and its graphics card / driver. In this benchmark is a look at the gaming performance of Oracle's VM VirtualBox 4.1 when using their "Chromium" driver to enable guest Linux OpenGL acceleration.

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.

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.

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.

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.

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.

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.

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.
