After developing LLVM/Clang 3.4 benchmarks earlier in the week from the System76 Gazelle Professional with Core i7 "Haswell" processor, out now are benchmarks of the latest GCC 4.9 development compiler.
While Intel is expected to show off their Bay Trail Atom SoCs (a.k.a. Valley View) next month that feature IvyBridge-class Intel HD graphics, the GMA-500 "Poulsbo" DRM driver is still being refined.
Chris Wilson has released another point update to the xf86-video-intel DDX.
Beignet is the controversial project to provide OpenCL/GPGPU support for modern Intel GPUs on Linux. Since the first Beignet release in April, this open-source Intel OpenCL project has been making lots of progress.
When it comes to open-source Linux graphics drivers, Intel is the company most committed to their success. Intel exclusively offers their Linux graphics support through a fully open-source stack while AMD and NVIDIA are mostly focused on their proprietary graphics drivers. AMD does have a handful of employees devoted to their open-source driver while NVIDIA dedicates no one and leaves it up to the Nouveau community for reverse-engineering.
While Mesa 9.2 hasn't even officially been released yet, with it already having been branched from its Git master code-base since last month, are there already some performance-beneficial changes living in master (Mesa 9.3-devel) worth writing home about? Here's some benchmarks.
For those OpenGL application and game developers seeking to optimize their program's performance for the Mesa hardware drivers, and more specifically the Intel HD Graphics support, here's some very useful information.
For those not actively following the Mesa Git repository, there continues to be new performance-optimizing patches flowing in from Intel's developers for their open-source Linux graphics driver.
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.
A new set of Linux GPU driver patches have emerged for allowing HDMI 4K 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.
Another week, another xf86-video-intel graphics driver update. This latest xf86-video-intel DDX driver update brings performing tuning for the Haswell GT3e graphics core, disables triple buffering for compositors, and other changes.
Intel has updated their "Linux Graphics Driver Installer" for making it easier to upgrade the Linux graphics stack on supported distributions.
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.
The xf86-video-intel 2.21.13 driver was released on Sunday by Intel's Chris Wilson. This latest Intel X.Org driver update has some performance regression fixes plus fixes the Intel X.Org driver to build on non-Linux systems.
The open-source PMU-Tools package for Linux allows for a number of performance monitoring units / performance counters to be tapped on the latest Intel processors. PMU-Tools builds on top of the Linux kernel's perf subsystem to offer a wealth of information to developers.
Intel has published open-source Linux kernel driver patches for their Many Integrated Core Xeon Phi X100 co-processors.
The Intel Haswell HD Graphics 4600 performance for OpenGL doesn't change much if trying out the experimental Linux 3.11 kernel.
Due to the incredible rate at which Chris Wilson has been pushing out new xf86-video-intel X.Org driver releases to optimize his "SNA" acceleration architecture, here are updated Intel Core i7 "Haswell" SNA vs. UXA 2D performance benchmarks.
The Linux 3.11-rc2 kernel isn't even out yet, but Intel's open-source developers have already begun lining up DRM kernel graphics driver changes for the Linux 3.12 kernel.
With the Linux 3.11-rc1 release, it's time now at Phoronix to start benchmarking the Linux 3.11 kernel. The first tests to run over the weekend were of Intel Ivy Bridge graphics, where a few regressions were spotted.
Intel's Ironlake hardware may be very old and not nearly as nice as the latest generation Haswell parts, but shipped today was a new patch-set for implementing hardware context support.
Chris Wilson has put out another speedy X.Org Intel graphics driver release, this time bumping it to version 2.21.12.
Intel Open-Source Technology Center developers are currently working on another feature of Intel's latest-generation Haswell architecture not currently exposed by their open-source Linux graphics driver.
Ian Romanick of Intel who generally has been serving as the release manager of new Mesa releases, has announced some planned changes for releasing Mesa 3D drivers.
For benefiting embedded Linux developers with greater system performance and power efficiency, Intel has ported their System Studio Extended software to Linux.
Chris Wilson has released yet another xf86-video-intel 2.21.x driver point release.
Intel released version 1.2.0 of libva and libva-intel-driver over the night. The updated Video Acceleration API (VA-API) now has support for MPEG-2 encoding along with new H.264 profile encoding API support.
Intel's Chris Wilson has done a Saturday morning release of the xf86-video-intel 2.21.10 driver to get out more performance tweaks and regression fixes.
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.
836 Intel news articles published on Phoronix.
