For those interested in XenGT as Intel's form of mediated GPU pass-through support on Linux, the newest quarterly update has surfaced.
Chris Wilson of Intel's Open-Source Technology Center hasn't yet managed the xf86-video-intel 3.0 DDX release, but over in kernel-space, he's just published a set of 70 new DRM patches for the Intel kernel driver.
There's more improvements in Mesa Git to talk about this week for Intel open-source customers, including those still on older "Gen4" graphics hardware.
Daniel Vetter of Intel today sent in more code for DRM-Next that in turn will be merged for the Linux 4.1 kernel. It was also signaled that the initial hardware enablement of the graphics processor on Intel's upcoming "Broxton" SoC might happen for this next version of the Linux kernel.
Intel Linux developers have landed a lot of Broadwell enablement code into Coreboot.
Intel is planning to enable the NIR intermediate representation by default within their open-source Mesa Linux graphics driver.
Intel previously committed an H.265 / HEVC video decoding API to the video acceleration VA-API interface. The Intel VA-API developers have now complemented that by adding a HEVC encode API to this open-source GPU-based video acceleration library.
Intel's open-source Linux development crew continues working on next-generation Skylake hardware support in a steadfast manner.
Intel has published a patch-set adding support for Intel's Trace Hub to the Linux kernel for carrying out full system debugging.
Just one week after Intel sent in their initial DRM driver updates for Linux 4.1, a second pull request has been submitted with more DRM graphics driver changes queued up for Linux 4.1.
For helping out ISVs and game developers test out their initial Vulkan code, they developed their own Intel Vulkan GPU graphics driver for Linux that they intend to open-source.
Yesterday I ran some benchmarks from the new Core i3 Broadwell NUC to see how the latest Mesa Git affects the OpenGL performance for the Core i3 5010U chip with HD Graphics 5500. Today I'm complementing that testing to see if the latest Linux kernel Git makes any difference for this low-end, low-power Broadwell chip.
While we're only in the middle of the Linux 3.20 kernel, for what might still be called Linux 4.0, Intel already has updated DRM driver code for testing that will not be merged until Linux 3.21 (or what might also be known as Linux 4.1).
As usual, the next version of the Linux kernel will bring a number of prominent changes to Intel's open-source DRM graphics driver.
Intel will begin shipping their first Skylake chips in the second half of this year.
While Intel's official Mesa DRI driver has supported "Gen8" Broadwell graphics for many months, today the support for these latest-generation HD/Iris Graphics processors landed within the unofficial ILO Gallium3D driver.
While we're still waiting on xf86-video-intel 3.0 to finally be released after the better part of two years in development, Chris Wilson continues piling on new functionality for the Intel X.Org driver.
For any Intel Haswell Linux users with Iris Graphics thinking of switching to the Linux 3.19 kernel when it's released in what might just be a few hours, be forewarned as testing this weekend revealed there looks to be an OpenGL performance regression attributed to this new kernel.
A few days back I shared A First Look At The Intel Broadwell NUC Kit. Since then I've run some of the first Linux benchmarks from this Intel NUC with Core i3 5010U "Broadwell" processor.
A set of fourteen patches were published today for the Intel Mesa DRI driver for implementing glMemoryBarrier() as needed by OpenGL 4.2 and newer.
I'm still benchmarking many laptops around here with the current build of Ubuntu 15.04 as part of my large forthcoming laptop comparison pitted against the new Lenovo ThinkPad X1 Carbon with Intel Broadwell processor. For another perspective on the Broadwell HD Graphics 5500 OpenGL performance, here's a laptop comparison against an old ThinkPad with discrete NVIDIA graphics.
As some extra Broadwell Linux performance numbers this morning, here's some brief test results for the Intel Core i7 5600U when testing the Intel P-State vs. ACPI CPUFreq frequency scaling drivers and the different scaling governors.
In the past few days when begining to deliver a number of initial Linux tests from Intel's new Broadwell processors, a number of Phoronix readers have inquired about the OpenCL and VA-API support for the new hardware.
The third-generation Lenovo ThinkPad X1 Carbon continues running well under Linux with its new Intel Core i7 5600U "Broadwell" processor sporting HD Graphics 5500. I'm enjoying this new ultrabook a lot and have been pushing it very hard for days with various Linux benchmarks.
Aside from the performance benefits of Broadwell, particularly in having greater graphics capabilities, laptops and ultrabook designs are much more power efficient than former Haswell products. Here's some quick tests I did today comparing the Broadwell-based Core i7 ThinkPad X1 Carbon to my former Haswell-based Core i7 ASUS Zenbook ultrabook.
Intel has already landed a lot of new DRM graphics code for the Linux 3.20 kernel but there's more in store for drm-next before calling it a week.
Longtime X developer Keith Packard has left Intel and their Linux graphics work in favor of picking up a gig at Hewlett-Packard.
While Intel's Open-Source Technology Center has publicly had Broadwell Linux GPU driver code to post public since the end of 2013 and they've already started on Skylake enablement, there's still yet-to-be-mainlined patches for the Linux kernel to benefit Broadwell graphics performance.
Ben Widawsky of Intel's Open-Source Technology Center rolled out a new experimental tool aptly called intel_frequency for manipulating the Intel GPU frequency under Linux.
Intel RealSense is a Kinect-like 3D camera. The Intel RealSense 3D camera is intended to have a variety of applications from 3D scanning to "immersive collaboration" to gaming, but sadly its Linux support isn't yet up to scratch.
