Intel GLSL On-Disk Shader Cache Enabled By Default

For Mesa 18.0 is the initial Intel shader cache support for archiving compiled GLSL shaders on-disk to speed up the load times of subsequent game loads and other benefits. For the Mesa 18.0 release the functionality isn't enabled by default but it will be for Mesa 18.1.

Initial Intel Icelake Support Lands In Mesa OpenGL Driver, Vulkan Support Started

A few days back I reported on Intel Icelake patches for the i965 Mesa driver in bringing up the OpenGL support now that several kernel patch series have been published for enabling these "Gen 11" graphics within the Direct Rendering Manager driver. This Icelake support has been quick to materialize even with Cannonlake hardware not yet being available.

Intel Sends Out Initial Open-Source Mesa 3D Driver Patches For Ice Lake

One month ago Intel's Open-Source Technology Center began posting the initial Linux driver enablement for Icelake "Gen 11" graphics, the generation succeeding this year's Cannonlake "Gen 10" hardware. That initial work focused on the DRM kernel driver while now they have posted the first Mesa patches.

Coffee Lake Support Finally Lands In Beignet OpenCL

Intel Coffee Lake CPUs began shipping in October and while their UHD Graphics are effectively re-branded Kabylake graphics, it's taken until today to get mainline support for Coffee Lake OpenCL support on Linux with Beignet.

Intel's Latest Icelake Patches Let The Display Light-Up

Earlier this month Intel open-source driver developers posted the initial graphics enablement for Icelake, the "Gen 11" graphics coming after the yet-to-be-launched "Gen 10" Cannonlake processors. The latest patches in this series have now been published for allowing initial Icelake display support.

Experimental KPTI Support For x86 32-bit Linux

For the Kernel Page Table Isolation (KPTI) support currently within the Linux kernel for addressing the Meltdown CPU vulnerability it's currently limited to 64-bit on the x86 side, but for the unfortunate souls still running x86 32-bit operating systems, SUSE is working on such support.

Open-Source HDCP Support Gets Extended To More Platforms

With the Linux 4.17 kernel (not the upcoming 4.16 cycle) there is likely to be added initial HDCP support to Intel's Direct Rendering Manager driver. Ahead of that this High-bandwidth Digital Content Protection support continues getting improved upon.

Benchmarking Retpoline Underflow Protection With Intel Skylake/Kabylake

Beyond the Retpoline support already found in the mainline Linux kernel, developers are working on Retpoline Underflow support that would be used for Intel Skylake and Kabylake CPUs. RETPOLINE_UNDERFLOW protects against falling back to a potentially poisoned indirect branch predictor when a return buffer underflows and this additional protection is needed for Intel Skylake/Kabylake processors. I ran a couple benchmarks.

Initial Intel Ice Lake PCH Support Posted

A few days back I wrote about open-source Intel developers posting their initial GPU driver patches for Icelake "Gen 11" graphics. That first code drop was just the tip of the iceberg unlike code drops for previous generations where they published the whole stack at once. But now the developers have already moved on to publishing more of the code.

Linux 4.17 To Likely Include Intel DRM Driver's HDCP Support

Back in November a Google developer proposed HDCP content protection support for the Intel Direct Rendering Manager (DRM) Linux driver that is based upon their code from Chrome OS / Chromium OS. It looks like that High-bandwidth Digital Content Protection support in the i915 DRM driver will come for Linux 4.17.

Cannonlake/Icelake Desktop CPUs Won't Have PKU Memory Protection Support

Support for Memory Protection Keys (a.k.a. PKU / PKEYs) was finished up this year in the Linux kernel, glibc, and related components. This memory protection feature premiered with Intel Xeon Scalable CPUs and is said to be coming to future desktop CPUs, but it doesn't look like that's happening for the Cannonlake or Icelake generations.
