Intel's open-source developers maintaining GVT-g for Linux graphics virtualization support for their hardware are working on migrating their development workflow from this code that's been out-of-tree since its inception to now being mainline.
Intel's open-source Mesa DRI driver has passed The Khronos Group's process for certifying it as a conformant OpenGL 4.5 implementation. This now rounds out the Intel open-source Linux stack with OpenGL 4.5, OpenGL ES 3.2, and Vulkan 1.0 certification.
In our Intel Kabylake benchmarks we have shown how Intel's P-State CPU frequency scaling driver used by most Linux distributions can lead to much lower performance with their latest-generation processors compared to the ACPI CPUFreq scaling driver. Fortunately, action is taking place for improving the P-State performance with Kabylake.
Developers working on Intel's Clear Linux distribution have taken to performance tuning of their stock PHP packages during their migration from PHP5 to PHP7.
Yesterday I published Linux benchmarks of the Celeron G3930, Intel's lowest-end Celeron CPU at the moment in the Kabylake family. This CPU goes for about $40 USD and you get a dual-core 2.9GHz processor with HD Graphics 610 (GT1). I had published a few OpenGL benchmarks in that review while for this article are some OpenCL compute numbers.
Back in December was talk of dropping the (unofficial) Intel "ILO" Gallium3D driver while now it's looking like that may move forward.
Intel's forthcoming Geminilake hardware has a native HDMI 2.0 controller and as such the open-source Intel Linux driver developers are working on proper HDMI 2.0 support within their kernel driver.
Mesa's "ANV" Intel Vulkan driver can now be built for Android.
For those curious how Intel's flagship Core i7 7700K "Kabylake" processor is performing under Linux, my sample arrived yesterday and I've begun putting the CPU through its paces.
Daniel Vetter, the i915 DRM kernel maintainer from Intel's Open-Source Technology Center, has announced their final set of feature changes to be queued in DRM-Next for the Linux 4.11 kernel.
Note to self: don't drop CPUs on the ground. But even with a bent Core i5 "Kabylake" processor, it still managed to work.
There's some early feature development work that's landed in Mesa Git this Friday as the initial feature development towards Mesa 17.1.
Intel developers today announced the release of Beignet 1.3 and it's by far their most significant release yet for this open-source OpenCL implementation for Intel graphics hardware.
With the forthcoming Linux 4.10 kernel there is finally support for Turbo Boost Max 3.0 as featured in some newer Intel CPUs. But, unfortunately, the code in Linux 4.10 doesn't work for all TBM3-capable systems out there, but a new kernel patch is being worked on for Linux 4.11 or later to make it work with more hardware.
With the Linux 4.10 kernel having initial but limited Intel Graphics Virtualization Tech support, you can begin playing with the experimental virtual GPU support using the upstream kernel and libvirt.
For those running older Intel "Ivy Bridge" hardware on Linux, OpenGL 4.0 support soon should arrive.
As a quick update from this morning's article about Intel's Mesa driver getting ready for OpenGL 4.5 on Haswell, that code has now landed.
It was just two weeks ago that Intel's Mesa driver finally crossed the threshold with Haswell for supporting OpenGL 4.0 and then last week OpenGL 4.2 was crossed for this older generation of Intel graphics hardware. Now, it looks like OpenGL 4.5 will be enabled for Haswell with the i965 Mesa driver.
There's a patch pending for the Intel DRM driver that in extreme select cases can boost the graphics performance by up to 60% but for most OpenGL workloads the gains will be much smaller.
When firing up Intel's Beignet OpenCL implementation on Clear Linux this weekend, I was surprised to see it was happily chugging along with many of our different CL benchmarks.
I'm still running more benchmarks in investigating the Core i5 7600K Linux performance and with even its graphics performance being slower than Skylake. I fired up Clear Linux on this Kaby Lake system this weekend and it's indeed faster than Ubuntu, though there still is some sort of fundamental issue at play with these new CPUs on Linux. But what is clear is that there are cases where the P-State CPU frequency scaling driver does perform very poorly over the mature, generic CPUFreq scaling driver.
Many free software advocates have been concerned by Intel's binary-only Management Engine (ME) built into the motherboards on newer generations of Intel motherboards. The good news is there is now a working, third-party approach for disabling the ME and reducing the risk of its binary blobs.
Skylake and newer hardware is set to have frame-buffer compression (FBC) enabled by default when the Linux 4.11 kernel rolls around in a few months. This feature can reduce power consumption while reducing memory bandwidth needed for screen refreshes.
Igalia developers have been doing a lot of work this past week from seeing their FP64 Haswell patches merged, issuing new Ivy Bridge FP64 patches for testing, Float64 support for the Intel Vulkan driver, and related work. The newest from Juan Suarez Romero on behalf of Igalian developers are the 11 patches needed for taking Intel's Mesa driver for Haswell to the OpenGL 4.2 milestone.
The work on supporting shaderFloat64 within Intel's "ANV" Mesa driver is now complete and merged into Mesa Git.
On Saturday I published Intel IvyBridge / Haswell /Broadwell / Skylake OpenGL and Vulkan Benchmarks On Linux 4.10 + Mesa 13.1 using various Core CPUs. But for some fun benchmarks this Sunday morning are GL/VLK results when using a Xeon E3 v5 Skylake CPU with HD Graphics P530.
It's been a good week for users of older Intel Haswell graphics on Linux: beyond landing FP64 support and then exposing OpenGL 4.0 support, this older generation of Intel graphics now has a couple more OpenGL ES 3.2 extensions.
This week Intel launched the desktop/socketed Kaby Lake CPUs. Over the next week will be many Linux CPU benchmarks on Phoronix so here is your last opportunity to put in any special benchmark requests.
I'm in the process of testing a lot of my different CPUs/APUs in preparation for some Kaby Lake Linux benchmarks next week with the Core i5 7600K and Core i7 7700K. Along the way with the different CPU benchmarks I've also been running some fresh integrated Linux graphics tests on the newer and interesting hardware.
Fresh off their work on landing the long-awaited Haswell FP64 support followed by today enabling OpenGL 4.0 for Haswell (along with revised Float64 patches for Intel's Vulkan driver), there is now the FP64 patches for Ivy Bridge with the patches that ultimately enable OpenGL 4.0 on this generation-older hardware.
