"Mega Drivers" Being Proposed For A Faster Mesa

Eric Anholt of Intel is currently working on some experimental Mesa code for shipping "Mega drivers", or building all of the Mesa/Gallium3D drivers together as a single shared object library file. There's some promise to this mega drivers concept in enhancing performance due to compiler/linker optimizations.

LLVM Working On Intel AVX-512 Support

Intel developers working on the LLVM compiler infrastructure have been working on AVX-512 instruction set support in recent days. Intel AVX-512 instructions support 512-bit SIMD instructions with providing twice the number of data elements handled by AVX/AVX2 with a single instruction and four times that of SSE instructions.

Running PC-BSD/FreeBSD 9.1 On Intel's Core i7 Haswell

In the two months since the launch of Intel's Haswell processors there's been a lot of coverage on Phoronix for this latest-generation hardware under Linux, including some of Windows and OS X too, but no BSD testing yet. That has now changed with our first report of using PC-BSD / FreeBSD 9.1 on an Intel Core i7 4770K.

Assessing The Current Intel Haswell Linux Experience

Since the Computex launch of Intel's much anticipated Haswell processors at the beginning of the month, there's been much Linux coverage on Phoronix concerning the compatibility and performance of these new Intel processors from both the processing and graphics sides. Here's a summary of all of our discoveries and findings over the past few weeks.

Is Intel Sandy Bridge Getting Faster On Linux?

With the extensive coverage on Phoronix this month of Intel's new Haswell processors on Linux, many articles have shown that when using the latest components (e.g. Linux 3.10 kernel and Mesa 9.2) that the OpenGL performance is a whole lot faster. But are these changes specific to Haswell or benefit Intel's driver as a whole? In this article are new benchmarks from an older Intel "Sandy Bridge" system with HD 3000 graphics to see whether the performance there is also improving with the latest Linux code.

Intel GPU Driver Tries To Rip Out FBDEV Support

Intel's Daniel Vetter is attempting for the Intel DRM graphics driver to remove support for its FBDEV frame-buffer layer with a new patch-set entitled "fbdev no more!", but will this finally usher in the killing of the Linux kernel's FBDEV subsystem?

Core i7 4770K - HD Graphics 4600 On New Linux Kernels

For the past week on Phoronix since the public debut of Intel's Haswell processors there has been a lot of coverage. The CPU performance is generally great but the Haswell Linux graphics support is still a work-in-progress even though its performance has already evolved a lot. This Sunday are some extra Core i7 4770K benchmarks.
