An LLVM-Based Intel GPU 3D Driver Won't Come Soon

This weekend in Brussels I heard about the state of Intel's initiative for migrating to an LLVM-based shader compiler for their open-source Mesa 3D driver to replace their existing custom compiler embedded within the driver. Unfortunately, the state of this LLVM-based compiler is rather meager.

Intel Still Tidying Up Linux Support For Haswell

Intel will be introducing their Haswell processors in the coming months. If using the Linux 3.8 kernel, GCC 4.7/4.8, Mesa 9.1, and other recent open-source Linux packages, you should be mostly set for experiencing the full benefits of the Ivy Bridge successor. However, there's still a few pieces of Haswell's Linux support still being worked out.

Intel Driver To Play A Bit Better With S3TC Compression

In addition to the Intel driver now always enabling floating-point textures, a patented feature but something that's required for GL3 compliance, the Intel DRI driver is set to play better with S3TC, the also patent-troubled but widely-used S3 Texture Compression.

HDA Intel Audio To Improve A Lot In Linux 3.9 Kernel

With we are only about half-way through the development of the Linux 3.8 kernel, there's already exciting features beginning to enter the development spotlight for Linux 3.9. One of the features coming to the Linux 3.9 kernel will be grand changes to the very common "HDA Intel" audio codec drivers.

Beignet: OpenCL/GPGPU Comes For Ivy Bridge On Linux

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 Still Playing With i830GM/845G Stability

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.

Intel's Cilk Plus Still Waiting To Get Into GCC

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.

2D Support On Old Intel Hardware: Nothing But Misery

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.

Trying Out DRM-Next With Intel Sandy Bridge

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.

Intel Finally Delivers Stable i830GM/i845G Driver

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.

Gallium3D Driver Comes For Intel Sandy/Ivy Bridge

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.
