Last week I wrote about Beignet as Intel's OpenCL Linux implementation for "Ivy Bridge" hardware. While the code was recently open-sourced, the future direction of this project is unknown.

Chris Wilson of Intel OTC has released yet another X.Org driver update in the xf86-video-intel 2.20 series. This latest DDX update does bring rendering improvements plus fixes for various performance regressions.

For the open-source Radeon and Nouveau graphics drivers on Linux, OpenCL/GPGPU support has been implemented via the "Clover" OpenCL state tracker with the Radeon/Nouveau drivers built atop the Gallium3D driver architecture. While Intel's latest hardware supports OpenCL with its graphics core, their open-source Linux driver has lacked any support, but that is changing.

Intel is still working on some minor xf86-video-intel driver changes to address stability issues for the very old i830GM and i845G chipsets. A new Intel X.Org driver update was released on Wednesday to take care of more changes.

Cilk Plus is one of the Intel initiatives to advance multi-threaded parallel programming by providing a set of C/C++ programming language extensions similar in nature to OpenMP. While Intel has had open-source Cilk Plus code for months, the compiler support has yet to be picked up by GCC.

Intel's TurboStat utility that's part of the Linux kernel is now capable of reading the wattage and temperature for modern Intel processors.

While Intel finally has stable i830/i845 graphics support for the decade-old Intel hardware that was notorious in recent years on Linux since the GEM/KMS migration, the 2D acceleration support is "nothing but misery" as described by an open-source Intel Linux developer.

When running some OpenGL performance benchmarks this week of the Radeon driver using "drm-next" code that's set to be merged into the Linux 3.8 kernel, some significant performance improvements were discovered thanks to AMD's code contribution. Curious to see if the Intel graphics performance is likely to change, I also ran some drm-next Linux benchmarks from an Intel Sandy Bridge system.

While the Intel 830GM and 845G chipsets were first introduced more than one decade ago, their graphics driver support has been botched for much of the time. As of today though, Intel Linux driver developers think they have taken care of the longstanding stability issues with this now ancient hardware.

In prior years there was the i965g driver that was developed independent of Intel and was targeting an open-source Gallium3D driver for Intel's newer chipsets. But unlike the i915g that was developed similar in nature, the i965g driver really never reached a working state and was ultimately removed. There is now a brand new "i965g" Gallium3D driver that is targeting support for Intel Sandy Bridge "Gen6" graphics and newer.

ETC2, the new royalty-free texture compression method that's required by OpenGL ES 3.0, now has support within mainline Mesa. However, for now this ETC2 support is limited to the Intel DRI driver.

Intel should finally have Haswell graphics support on Linux in shape with the Linux 3.8 kernel after earlier admitting they screwed up, not all areas of the open-source GPU driver support are polished ahead of the big Haswell CPU launch in 2013.

Shortly after improving the HyperZ support in R300g, Marek Olšák has now enabled HyperZ support by default for ATI R500 (Radeon X1000 series) GPUs.

It's been announced this morning that Intel is acquiring ZiiLabs, the subsidiary of Creative Labs that previously was 3DLabs. Intel is gaining "certain engineering resources and assets" plus licensing rights to certain ZiiLabs patents and other technologies surrounding the GPU.

Linux kernel developers have created an Intel PowerClamp driver, which is an experiment with idle injection for Intel hardware to take advantage of power-efficient package-level C-states for power capping and passive thermal control. Separately, Intel RAPL (Running Average Power Limit) support is now exposed through TurboStat.
