While Intel already landed a big round of code into DRM-Next as Linux 4.7 material, the train has not stopped and more fresh code is now in testing via the intel-drm-testing branch for integration into a future kernel release.
Following the recent Iris Graphics of Xubuntu 16.04 vs. Clear Linux vs. Fedora 23 I had some extra time so I decided to fire up Beignet on Ubuntu 16.04 for this Haswell ultrabook.
Broxton was to be Intel's 2016 Atom SoC platform for phones and tablets. Broxton was to be using 14nm Goldmont CPU cores and Skylake graphics, but now it's no more.
While the Intel Mesa driver remains at OpenGL 3.3 due to missing FP64 support, that code continues to be worked on by Igalia and Intel's OTC developers. Patches for a related extension, ARB_vertex_attrib_64bit, have also now been published that will clear Intel's Mesa driver requirements for OpenGL 4.1.
Intel is finally offering up a kernel driver it's seeking to mainline for providing support for Secure Guard Extensions (SGX).
Intel quietly announced last week the publishing of the complete source code around the firmware / real-time operating system for the Arduino 101 and Genuino 101 boards.
My NICs appear to enjoy sleeping in with the mornings being particularly brutal on the network hardware.
Daniel Vetter of Intel OTC sent in another round of feature updates for DRM-Next to in turn premiere with Linux 4.7.
One of the new set of patches published this week for the Intel DRM kernel graphics driver is for engine reset and recovery support for Broadwell "Gen8" graphics hardware and newer under Linux.
Daniel Vetter of Intel OTC has sent out an announcement about another round of i915 DRM kernel driver code that's ready for testing by developers and the community.
Intel developers are planning to merge their branched version of Mesa with their Vulkan graphics driver into mainline Mesa in just a matter of days.
Here are some of my earliest Linux 4.6 kernel benchmarks out there from a few different subsystems with the tests happening from a Xeon E5 Haswell system with AMD Radeon graphics.
While the Linux 4.6 kernel is enabling FBC and PSR by default in the Intel graphics driver, it's only for select generations of Intel hardware for these power-saving Frame-Buffer Compression and Panel Self Refresh features. With Intel Skylake, FBC support remains a work in progress.
Intel MPX memory protection aims to safeguard against buffer overflows in programs assuming you have a supported processor and software stack. Over at Intel's Open-Source Technology Center they published a guide this week on making use of Intel MPX under Linux.
New firmware blobs have been updated in linux-firmware Git this morning for Skylake affecting both audio and graphics.
Support for Memory Protection Keys (PKeys/MPK) that will be found on future Intel CPUs is being proposed for inclusion into Linux 4.6.
As covered already in a few articles and in our forums, Mesa 11.2 isn't yet found by default on Ubuntu 16.04 but the developers have a feature freeze exception for still landing this feature update to the Mesa 3D user-space drivers and currently have it staged via a Personal Package Archive.
Intel OTC's PowerTOP utility has been around for nearly a decade for making it easy to carry out power optimization tweaks on Intel Linux systems. However, is this program still useful or are modern Linux distributions and upstream code now better optimized by default for delivering an ideal power-savings experience? As it's been a while since the last time I tried PowerTOP, I fired it up today on an Intel Haswell ultrabook running a development snapshot of Ubuntu 16.04.
To many users, Intel's codename of Bay Trail for the recent Atom SoCs would be more accurate if it was named Bay Fail.
Intel's Daniel Vetter on Friday sent in another batch of DRM-Next changes for the upcoming Linux 4.6 kernel cycle. This pull does contain some interesting open-source graphics changes for this Intel DRM driver.
Engineers at Intel's Open-Source Technology Center have implemented native, one-copy texture uploads for Chrome/Chromium OS when using Intel graphics processors.
With Clear Linux continuing to outperform other Linux distributions on Intel hardware, I was curious to see how the Intel OTC Linux distribution was performing when trying it with one of the new Xeon CPUs at our disposal for testing.
Consulting firm Igalia has been working on FP64 support within the Mesa i965 driver on the behalf of Intel. It looks like they'll soon be wrapped up with this support and that in turn means there will be OpenGL 4.0+ compliance!
After the tests this weekend of Intel Hyper Threading and core scaling with the new Intel Xeon E3 "Skylake" processor, I proceeded to do some Turbo Boost benchmarking.
As some extra benchmarks following this week's 9-Way Intel Xeon E3 v5 Skylake Benchmarks On Ubuntu Linux, some Phoronix Premium readers wanted to see how well Hyper Threading worked for these latest-generation Xeon E3 processors and the core scaling efficiency of Skylake.
A rather large DRM fixes pull request landed tonight in hoping to address graphics driver issues with Intel's latest-generation Skylake hardware.
While it doesn't yet support OpenCL 2.0/2.1, Intel Open Source Technology Center's Beignet doesn't really get the attention it deserves and sadly isn't shipping out-of-the-box on most Linux distributions.
For those curious about the performance impact between the CPUFreq and P-State scaling drivers and the different scaling governors when using an Intel Core i5 "Skylake" CPU with the latest Linux 4.5 kernel, here are some fresh benchmarks.
Intel is prepping Cannonlake processor support inside the LLVM Clang compiler.
There isn't much a better joy in life than unexpectedly finding nine Intel latest-generation (Skylake) Xeon processors at your doorstep.
