Francisco Jerez has been tackling L3 cache partitioning for the Intel DRM driver, which will yield some interesting possibilities moving forward.
Due to the Linux scheduler changes that already landed in Linux Git having a rework that potentially affects every SMP workload out there and some power management changes that affect Skylake, I decided to run some early Linux 4.3 kernel code as of Git this morning on the Core i5 6600K "Skylake" system.
As of today in Mesa Git, the royalty-free Adaptive Scalable Texture Compression (ASTC) is now supported in Mesa Git for Skylake graphics hardware.
One of the recent project's out of the Intel Open-Source Technology Center has been to track down delays in the Linux kernel's suspend and resume process.
Last year Intel developers added HEVC decode support to VA-API followed a few months later by HEVC encode support to this Video Acceleration API used by the Intel open-source driver on Linux.
Continuing on from the articles earlier today about Linux 4.3 Will Let Skylake Graphics Play Out-Of-The-Box and Building Mesa 11.0 On Ubuntu Linux, here are a few very early test results when comparing the performance of the Intel Skylake graphics on Ubuntu 15.04 to the DRM-Next code to be integrated into Linux 4.3 as well as Mesa 11.0 in its near-final state.
In my testing of Intel's Skylake processor this month, there's been a silly/annoying issue that will fortunately be a problem of the past with the Linux 4.3 kernel.
Following last month's update to Beignet, the Intel open-source project for providing open-source OpenCL compute support for their HD/Iris Graphics hardware, that brought Skylake support, SPIR, and other updates, there was some hope that OpenCL 2.0 support might become a greater focus to complement Beignet's OpenCL 1.2 support. Sadly, it looks like things are still moving slowly on the CL 2.0 front.
In the earlier days of Wayland, Intel was known for contributing a lot of resources toward this next-generation display technology to unseat the X.Org Server, but these days their contributions have been minimal.
Intel is quite close to finishing up support for OpenGL ES 3.1 within their open-source Mesa driver.
Andi Kleen of Intel announced today the release of Simple-PT, a simple Processor Trace implementation for Linux.
Intel has published some documentation concerning the compute architecture for the Intel Skylake "Gen9" hardware.
If you want to see how your own Linux system(s) compare to the Intel Core i5 6600K "Skylake" processor, here are some standalone benchmarks.
Earlier today I wrote about the Intel Core i5 6600K "Skylake" running fine on Ubuntu Linux compared to the issues encountered when running the i7-5775C Broadwell processor. This Intel Skylake CPU is running fine so far on Linux but there is a minor workaround that many users will experience if upgrading to a Skylake processor in the next few months.
As a quick update to Intel Core i5 6600K Skylake CPU Arrives: What Linux Tests Would You Like To See?, this brand new processor is playing nicely on Ubuntu Linux.
While the RadeonSI and Nouveau NVC0 Gallium3D drivers are now at OpenGL 4.1 compliance, the open-source Intel Mesa driver remains stuck at OpenGL 3.3. Blocking the Intel driver from OpenGL 4.0 compliance is FP64 and tessellation shader sub-routine. While work is underway on both extensions -- plus ARB_vertex_attrib_64bit for OpenGL 4.1 -- it looks like the FP64 support may not be too far out.
I now have my hands on an Intel Core i5 6600K "Skylake" processor for Linux benchmarking!
A bug affecting the open-source Intel Linux graphics driver appears to be responsible for many reports of KDE's Plasma 5 being unstable or causing crashes.
This morning from Germany Intel announced the release of the first Skylake desktop processors alongside the new Intel Z170 chipset.
Beignet, the project for providing open-source OpenCL support on Intel Iris/HD Graphics hardware, has released a new version of their Intel OpenCL implementation for Linux systems.
The FFmpeg project and its forked Libav have added support for new video decoders based on libmfx, technology from the Intel Media SDK.
Daniel Vetter of Intel's Open-Source Technology Center has sent in many Intel DRM driver changes to be queued up in DRM-Next for the Linux 4.3 kernel.
This week Mesa development is very exciting with OpenGL 4.0~4.1 support being reached and the open-source hardware drivers now just filling in their gaps. Intel's Mesa i965 DRI driver is getting ready to declare OpenGL 4.0 compliance.
This past weekend I posted an open-source Linux graphics driver comparison with an A10-7870K Godavari vs. i7-4790K Haswell vs. i7-5775C Broadwell. Beyond the already-published discrete AMD/NVIDIA GPU results to see how Intel's socketed Broadwell with Iris Pro 6200 Graphics stack up, there were also requests from readers for seeing some Haswell Iris results.
Intel has contributed Skylake SoC support to Coreboot.
This week I started testing Intel's new NUC5CPYH NUC as the first device with a Braswell SoC (not to be confused with Broadwell). The tests are progressing but the out-of-the-box experience hasn't been one of the best for Intel.
While I'm still working on my full Intel Core i7 5775C Linux review of this socketed Broadwell processor with Iris Pro Graphics 6200, and still working through some strange issues, I do have some Steam Linux gaming figures to share tonight for those interested in how Intel's latest-generation Iris Graphics are performing with the open-source Mesa driver stack.
It's been over a week now playing with the Intel Core i7 5775C on Linux and unfortunately problems persist even after buying another Intel Z97 motherboard.
If you have been interested in an Intel NUC as a 4-inch, low-power computer, the Braswell-based NUC5CPYH is finally in-stock and shipping at major Internet retailers.
Earlier today I wrote about how Intel has a lot of Linux graphics developers (likely 30~50) and is by far the company with the most active developers working on the open-source graphics stack. Here's some other numbers as part of the mailing list parsing for the other active companies, including NVIDIA, AMD, and Samsung.
