While Intel's Beignet is a terrific project especially when it comes to being a leading open-source OpenCL implementation that works with OpenCL 2.0 on GPUs (something that can't be said for Radeon with its open-source OpenCL stack consistently lacking and Nouveau not really being usable either), the sad part of it is that Beignet is consistently slow in supporting new versions of LLVM.
Intel's open-source Linux graphics driver developers have begun publishing patches for initial hardware enablement of Cannonlake's "Gen 10" graphics and the Cannonpoint PCH.
An initiative taking place within the Intel open-source Linux driver camp is trying to effectively move libdrm_intel -- the Intel-specific code for the DRM library -- into the i965 Mesa driver itself.
Intel has queued changes for their GVT-g graphics driver stack for Linux 4.12, allowing some improvements around their newly-mainlined graphics virtualization tech support for running VMs with accelerated graphics capabilities.
With the upcoming Linux 4.11 kernel release there is better support for Intel Turbo Boost Max 3.0 after originally it didn't look like this feature would be available for Linux.

For months there have been Intel developers working on 5-level paging to increase Linux's virtual/physical address space limitations and with Linux 4.12 it looks like that will be supported.
With Broadwell "Gen 8" graphics and newer, there is better engine reset support in case of problems or hangs. The Intel DRM driver is still being wired up to take advantage of this better support under Linux.
Tuning the P-State CPU frequency scaling driver for the Linux kernel feels like a never-ending process. While it's been around for years and continues to be refined, for some Intel CPUs on some workloads, the CPUFreq scaling driver leads to be better performance and even Intel's own Clear Linux distribution is using CPUFreq by default. With Linux 4.12, more intel_pstate revisions are taking place.
Intel's open-source "ANV" Vulkan Linux driver is prepping support for the experimental VK_KHX_multiview extension.

A bug-fix release was pushed out this morning for Intel's Beignet open-source GPU-based OpenCL implementation.
Intel's Mesa driver is exposing additional performance counters now for helping game/application debuggers better profile the performance of their software on Intel HD/Iris Graphics hardware.
Intel is off to the races in preparing their new feature material work they plan to have introduced for the Linux 4.12 kernel, even though Linux 4.11-rc1 was just introduced on Monday and thus still nearly two months until the 4.12 merge window.
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.

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.

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.
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.
