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.

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.

Intel's Mesa DRI driver now is unconditionally enabling floating-point textures. Up to this point, the floating-point textures feature of GL3 hasn't been enabled by default due to patent worries.

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.

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.

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.
