Earlier today I posted some Linux game CPU scaling benchmarks using a Core i7 6800K Broadwell-E For showing how current Linux games make use of (or not) multiple CPU cores, which originated from discussions by Linux gamers following the AMD Ryzen CPU launch with how many cores are really needed. While going through the process of running those Linux game CPU scaling benchmarks, I also ran some other workloads for those curious.
Intel's Daniel Vetter has updated their drm-intel-testing tree with early code to begin testing that should end up being queued for the Linux 4.12 kernel.
Intel's "SWR" software rasterizer living within Mesa now has support for OpenGL geometry shaders.
Intel's set to enable atomic mode-setting by default with code slated to land for the Linux 4.12 kernel.
Besides recent Intel graphics hardware making use of firmware binary blobs now for the GuC/HuC functionality, Intel audio hardware continues in making use of firmware binary-only blobs for audio support.
Intel's ANV Vulkan driver in Mesa Git has picked up support for two more extensions of this week's big Vulkan update.
Now that Vulkan's external memory patches are now public with today's Vulkan 1.0.42 big update, the Intel ANV open-source Vulkan driver is getting ready to roll out their support for their new extensions.
Better support for Intel Turbo Boost Max 3.0 are among the changes to find with the platform-drivers-x86 updates for the Linux 4.11 kernel.
Intel's "ANV" Vulkan Linux driver has landed the support for enabling MSAA compression.
There was some work years ago for supporting Intel's own INTEL_performance_query OpenGL extension it was dropped in January for a rework and now is back in Mesa 17.1-devel.
For those stuck with older Intel Sandy Bridge hardware, the integrated graphics with Mesa Git should be capable of supporting WebGL 2.0.
Intel Linux developers have partially reverted Mesa work done years ago to drop the default OpenGL behavior with the older i915 driver from exposing OpenGL 2.0+ support to now only having OpenGL 1.4 out-of-the-box.
If you are using Intel Broadwell graphics with Mesa's ANV Vulkan driver, the performance should be better for Dota 2 and potentially other workloads.
It looks like Feral Interactive might be getting closer to releasing their first Linux game port using Vulkan.
In yesterday's Core i3 2100 "Sandy Bridge" vs. Core i3 7100 "Kabylake" comparison I included all of the power consumption and performance-per-Watt results. If you are looking for additional power numbers from other Kabylake CPUs, here is some additional data.
The patch landed in Intel's drm-intel-next-queued branch this week for enabling atomic support by default on the hardware platforms where it's fully supported.
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.
