Radeon HyperZ In Open-Source On Older Hardware

Recently there has been a lot of talk about Hierarchical-Z/HyperZ support for R600g since its set to provide a measurable performance benefit the open-source Radeon driver for modern GPUs. This support has still not been mainlined and there are still a few issues to work out, but at least the support is stable for the older "R300g" driver and has been around for quite a while at this point. For those wondering what to expect from HiZ/HyperZ performance boosts, here is a preview.

Nouveau 2D Still Has Room For Improvement

Besides video decoding, re-clocking / performance improvements, OpenCL, and other areas, the Nouveau driver still has room to advance when it comes to 2D performance.

Morphological Anti-Aliasing With Mesa 8.0

One of the less talked about features of Mesa 8.0 is its ability to handle MLAA, which is short for Morphological Anti-Aliasing. But how does MLAA on the open-source graphics drivers affect the OpenGL performance and is it worth it for boosting the image quality through this anti-aliasing technique? In this article are some benchmarks of MLAA under Mesa 8.0.

VMware's Virtual GPU Driver Is Running Fast

For the past few years VMware has been improving the graphics acceleration support that is available via their virtualization platform. VMware -- through their 2008 acquisition of Tungsten Graphics -- has effectively re-written their graphics driver for their virtual "SVGA II" GPU to take advantage of the Gallium3D driver architecture, a new acceleration architecture, and many other improvements. This work has finally come together and is now working rather nicely.

Intel Gallium3D For Mesa 8.0

With the Mesa 8.0 release right around the corner, in recent weeks there have been a number of benchmarks on Phoronix looking at this latest open-source OpenGL library and its drivers, including Gallium3D. In this article though are new benchmarks from one of the areas not explored yet: the Intel Gallium3D driver performance.

Intel RC6 Support On The Sandy Bridge Desktop

While RC6 support remains off-by-default as Intel developers are faced by RC6-related bugs affecting a small minority of Sandy Bridge users, this power-savings feature is not limited to only Intel mobile graphics. As discovered at Phoronix, RC6 can manage to boost the graphics performance beyond just extending your battery life. The RC6 performance boost is also quite visible on Intel Sandy Bridge desktop hardware too.

Having SNAppy Intel 2D Acceleration In 2012

Here's a new look at Intel's Sandy Bridge New Acceleration (SNA) architecture within their DDX graphics driver. Testing in this article was done across three systems (mobile and desktop class Sandy Bridge hardware as well as an Ironlake system) seeing how well the latest code is performing in an effort to provide a better Intel 2D experience.

Nouveau Reclocking: Buggy, But Can Boost Performance

Over the weekend I shared that the Nouveau driver project, which seeks to provide an open-source NVIDIA graphics driver for Linux and other platforms via reverse-engineering, hit a major milestone. The Nouveau driver now supports re-clocking for several generations of NVIDIA GeForce hardware, which allows the open-source driver to put the graphics cards at their properly designed operating frequencies for maximum performance. This can result in the Nouveau driver performing much better against the official closed-source NVIDIA graphics driver, but the support is still very experimental. Initial testing over the weekend found this support to perform well when it works, but that overall it is still very buggy.

Preview: Intel's Open-Source Driver Can Beat Mac OS X

Thanks to recent advancements by Intel's Open-Source Technology Center, the open-source Linux graphics driver not only supports more OpenGL 3.0 functionality than Apple's Intel graphics driver for Mac OS X, but the performance is more competitive. In some cases, the OpenGL performance is now superior under Linux with the open-source driver that is developed by Intel in conjunction with the free software community. This article is looking at the performance of Intel Sandy Bridge graphics under Mac OS X 10.7 "Lion" and Ubuntu Linux.

An Open-Source, Reverse-Engineered Mali GPU Driver

There is some exciting news to break today on Phoronix... Coming up at FOSDEM (the Free Open-Source Developers' European Meeting in Brussels) will be the formal announcement of an open-source, reverse-engineered graphics driver for the ARM Mali graphics processor. OpenGL ES triangles are in action on open-source code. Will this be the start of fully open-source ARM graphics drivers for Android and Linux?
