OpenGL Compute Shader support appears about ready for the open-source Intel i965 Mesa DRI driver!
Since August I've been delivering various Linux benchmarks of the Core i5 6600K "Skylake" processor, but unfortunately don't have access yet to a i7-6700K Linux box. Fortunately, thanks to the open-source Phoronix Test Suite benchmarking software and the OpenBenchmarking.org collaborative cloud component, there are already numerous result files.
Intel is getting quite close to having OpenGL ES 3.1 support with their Mesa Linux graphics driver.
One month after the Gallium3D drivers gained support for this extension, the Intel i965 driver now handles OpenGL 4.5's ARB_texture_barrier.
Shashank Sharma of Intel's Open-Source Technology Center recently published a set of twenty-three patches for implementing color management support within the DRM driver layer.
Thomas Wood at Intel has announced intel-gpu-tools 1.12 as this quarter's update to this open-source project comprised of various test cases and developer tools for the open-source Intel Linux graphics driver.
While there's been an Intel OpenGL 4.4 Windows driver available for the latest HD/Iris Graphics hardware since earlier this year, it seems out now is their first production driver release for Windows 7 / 8.1 / 10 that supports OpenGL 4.4 for all their capable hardware that includes Skylake.
For those that follow the various Linux graphics mailing lists may have noticed several updated patches today for the "soft pinning" work to the Intel open-source graphics driver.
Intel's xf86-video-intel 3.0 display driver has now been in development for two years, but it doesn't look like they are in a rush to release it before Wayland takes over the Linux desktop.
The DRM changes landed in Linux 4.3 already and we've written about the prominent changes for these kernel graphics drivers for the next Linux kernel release.
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.
