A month ago we compared Intel's graphics performance between Ubuntu 8.10 and the latest Ubuntu 9.04 daily snapshot at the time. With those tests we found Intel's performance had degraded significantly. However, with many new graphics packages having been released since then, we have carried out some additional tests this morning to look at where the Intel Linux graphics performance stands today.

Earlier this week we delivered results from a comparison between the Catalyst and X.Org Radeon drivers looking at the R500 2D performance. With a lot of interest having been generated from that, we have now carried out the same set of tests again but this time using an ATI Radeon HD 4850 (RV770) graphics card and the experimental EXA support.

Four months after Mesa 7.2 was released, Mesa 7.3 has now officially surfaced. Mesa 7.3 has been in testing since earlier this month with it having gone through three release candidates. The new features found in this latest version of the standard Open-Source OpenGL stack is proper support for GLSL 1.20 and the Intel DRI driver now supports the Graphics Execution Manager and Direct Rendering Infrastructure 2.

The 42nd edition of the Nouveau Companion is now available to provide an update on the status of this community project to provide an open-source 2D/3D driver for all of NVIDIA's graphics hardware. Covered in this developer update is the status of the Nouveau driver on newer NVIDIA hardware, work underway on NV20 Gallium3D code, the LLVM back-end for Gallium3D progressing, the work that's left on kernel mode-setting support, and the GEM / TTM memory management work. The lack of a stabilized memory manager for the Nouveau kernel mode-setting driver is what's postponing a stable 2D driver release.

One of the common complaints about the ATI Catalyst Linux driver is slow 2D performance, but is this really the case? Does AMD's binary-only Linux driver have 2D performance issues that could actually make it run slower than the open-source driver developed by the X.Org community through specifications released by AMD? In this article we have run a total of 28 benchmarks looking squarely at the 2D performance between the Catalyst (fglrx) driver and the xf86-video-ati (Radeon) drivers on Ubuntu Linux.

Just a little more than a week after AMD openly released R600/700 GPU code to begin development of an open-source 3D driver for their ATI Radeon HD 2000/3000/4000 hardware, a disassembler and table dumper for their video BIOS abstraction layer has been released to developers. This tool called AtomDis was used early on in the development of the RadeonHD driver by Novell and is now being released under the GNU GPLv2 license to assist interested open-source developers or act as an instrument to those learning about graphics processor programming.

On Monday AMD released the open-source R600/700 3D code to begin fostering the development of an open-source 3D driver for their newer ATI hardware while the related programming documentation still on the way. This code that's finally out in the public domain brings basic EXA acceleration and X-Video support, but on the 3D side there isn't any usable OpenGL support. It is expected that there will be a modest level of open-source 3D support for the ATI R600 and R700 series in the first half of 2008 for end-users, but for now there is just the DRM code and an r600_demo program. In this article we are taking a brief look at this r600_demo debugging utility on the RV770 hardware.

Since earlier this year we have been waiting for AMD to release documentation and/or code on the ATI R600 series concerning 3D acceleration so that the open-source Linux drivers can begin to support the newer ATI graphics processors. It has taken longer than expected for AMD to complete and release this information, but it's now available. AMD has released the fundamental Linux code needed to begin fostering the development of an open-source R600 3D driver. Furthermore, this code also concerns the latest R700 series of graphics processors! The microcode for the newest GPUs has also been released.

Subsequent to the introduction of the Graphics Execution Manager earlier this year, Intel had introduced a new acceleration architecture. UXA, or the UMA Acceleration Architecture, was developed as a temporary solution based upon the EXA architecture but with support for the kernel-driven GEM memory management. How though does the UXA performance compare to that of EXA? In this article we have ran some benchmarking looking at the Intel graphics performance.

The past year has brought several invasive changes to the Intel Linux graphics stack with the introduction of the Graphics Execution Manager for GPU memory management within the kernel, support for the Direct Rendering Infrastructure 2, and kernel mode-setting finally getting ready to enter the limelight. How though has the work this year affected the overall performance of Intel integrated graphics on Linux? In this article we have run a few benchmarks that show where the driver was at a few months ago and where it is today.
