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.
While it didn't make it for the Linux 3.19 kernel merge window, an Intel developer is still working on the Imagination PowerVR VPU.
Hitting the Intel DRM tree this week was the much anticipated Haswell performance patch that was previously talked up by LunarG for benefiting Valve's OpenGL games on Linux. I've ran a few quick benchmarks today of the new Linux kernel code.
Along with many other announcements out of Intel this week for the Consumer Electronic Show, Intel officially lifted the lid on their new Broadwell NUCs!
Back in November I wrote about a Major Performance Breakthrough Discovered For Intel's Mesa Driver due to testing done by LunarG and uncovered with the help of Intel. That performance-boosting patch has been queued up for drm-intel-next thus meaning it will be present with the next major kernel cycle -- the Linux 3.20 kernel.
On Sunday I posted some benchmarks looking at Intel Haswell HD Graphics performance between 2013 and 2014, but for users of older "Ivy Bridge" graphics how does the performance comparison? In this article are Intel HD Graphics 4000 benchmarks between 2012 and 2014.
The Intel X.Org driver (xf86-video-intel 3.0) driver has been in pre-release form since September 2013 and now after having gone through many development revisions, xf86-video-intel 3.0 might be on final approach.
Intel's open-source team on Friday released intel-gpu-tools 1.9 as the latest version of this collection of tools used generally for testing and debugging purposes.
Intel's Edison Module is a development platform for prototyping wearable computing devices and IoT devices. Here's some Linux benchmarks with the Intel Edison running on Debian.
Intel developers have added the necessary code for the Video Acceleration API (VA-API) to offer support for decoding H.265/HEVC content.
The Linux 3.19 kernel that's a few weeks out still from officially being under development is quite heavy on the changes.
While we've been quite excited to get our hands on Cherry Trail hardware after the great encounters with Bay Trail on Linux, it looks like we'll be waiting a few more months.
For those wondering whether there will be any exciting improvements with the Intel DRM graphics driver in the Linux 3.18 kernel, here's some OpenGL performance benchmarks.
After two years of development by the Intel Open-Source Technology Center China crew, Beignet 1.0.0 was released this week for providing open-source OpenCL support on Linux.
Intel has sent in another round of graphics driver changes to be queued up in DRM-Next for the Linux 3.19 kernel.
We're still likely about one year out before seeing any Skylake processors released from Intel, but their open-source Skylake graphics enablement continues to flow.
This week Intel updated its Linux Graphics Installer for Fedora 20 and Ubuntu 14.04, but as usual, it's really nothing too special and doesn't earn my high recommendation as there's better ways for users to be running the latest open-source graphics code.
