Last year on earlier versions of the Linux kernel we've uncovered performance issues around Intel's P-State / CPUfreq driver that was causing adverse performance in certain configurations. While it looked like most of the Intel CPU clocking issues were resolved in more recent versions of the Linux kernel, it looks like some Linux performance problems are present in Linux 3.14.
Intel Linux developers have been pursuing work on creating a DRM color manager for Linux to standardize some interfaces related to color management for the DRM GPU drivers.
For supporting Linux networking on very small embedded systems like the Intel Quark, developers at Intel are working on a lightweight networking stack to fit on such systems.
For several months now Intel has been working on graphics virtualization support for their HD Graphics hardware on Linux for use by virtual machines. One of their big projects has been XenGT for mediated GPU pass-through with Xen, but here's a full rundown of what they have going for them right now.
Intel developers landed the bulk of the support into Mesa for supporting the GL_INTEL_performance_query extension, which should be able to assist Linux game developers and driver developers in better optimizing software/games for the open-source Linux graphics drivers.
Eight months ago today was the first development release of xf86-video-intel 3.0, the X.Org Intel DDX driver, with support for SNA by default and XMir. While Intel reverted their plans to support XMir, this major Intel DDX driver update still hasn't surfaced.
Intel has submitted their first drm-next pull request of the Intel Linux graphics driver changes aimed for the Linux 3.16 kernel.
The Intel P-State driver that's found in modern versions of the Linux kernel as a replacement to the older CPUfreq code is getting tuned for better performance while boasting greater power-savings.
A Linux developer at Intel has proposed a new CPU load metric for power-efficient scheduling by the Linux kernel.
Intel next week is expected to begin shipping a new NUC Kit that is fan-less and suited for "value-conscious businesses and organizations." This new NUC Kit has just a single-core "Bay Trail" processor that runs at 5 Watts but overall it looks like it could have some interesting applications if the price is right.
After yesterday delivering some early Linux 3.15 benchmarks using an Intel Core i7 and AMD Radeon graphics, here's some brief and RC1-stage tests looking at Intel "Haswell" HD Graphics 4600 with the new kernel.
Based upon recent open-source Intel Linux graphics driver patches, the high-end Intel Broadwell "GT3" graphics core will feature dual BSD rings for video decoding.
A few days ago I wrote about Intel adding Cherryview support to their Mesa 3D driver and now waking up this morning they have dropped a huge patch bomb that implements Cherryview Atom support within their DRM kernel driver. We now have a much better understanding for the Cherryview graphics hardware capabilities for when these Atom SoCs begin to ship in some months down the road.
After yesterday's article explaining how-to upgrade the Linux kernel and Mesa/X.Org drivers on Ubuntu 14.04 LTS, I ran some benchmarks from an Intel Atom E3825 Bay Trail system to see whether the newer kernel and Mesa components made a difference for the low-end, low-power hardware compared to what's being shipped by default in Ubuntu 14.04.
At the Intel Developer Forum in Shenzhen, China, Intel has announced Braswell as a new processor to succeed Bay Trail within low-end PCs, laptops, and Chromebooks.
Intel has lined up many exciting open-source graphics driver improvements for their DRM kernel module with the Linux 3.15 release.
Support for the latest Advanced Vector Extensions will be supported by the next Linux kernel release.
For those Intel owners -- namely those with vintage Intel hardware -- the days of using user-space mode-setting (UMS) for the open-source Linux graphics driver are running out.
Cherryview Atom SoCs aren't being released for several months but the first bits of hardware enablement have landed within the open-source Mesa 3D Linux graphics driver. Cherryview with the Cherry Trail platform is the next-generation successor to the wonderful Bay Trail hardware.
Intel was at the Linux Foundation Collaboration Summit this week promoting Tizen's In-Vehicle Infotainment initiatives for having a Linux-based Wayland environment within automobiles.
FBC (Frame-Buffer Compression) support within Intel's DRM graphics driver for Linux can lead to power-savings, but it still isn't turned on by default.
A series of commits hitting Mesa's mainline Git this afternoon offer up some multi-sample anti-aliasing (MSAA) improvements for the Intel open-source graphics driver.
While there have been pre-releases of the xf86-video-intel 3.0 X.Org driver going back to last September, it's still not ready to be released, but a new feature update was made available.
Intel Linux developers have enabled EWA Anisotropic Filtering support within their Mesa 3D driver after discovering their classic AF support might have not been working.
Intel's Haihao Xiang has announced the VA-API 1.3.0 pre1 release. The big theme of VA-API 1.3 is VP8 and Broadwell support.
Intel developers have announced the release of intel-gpu-tools 1.6, for developers and others testing Intel's Linux graphics driver stack.
Intel Mesa developers have added support to their open-source Mesa Linux graphics driver for the GL_INTEL_performance_query extension, which is yet another OpenGL extension exposing performance diagnostic information.
For those curious about the performance of Intel's "Quark" x86 SoC for very low-power applications, including wearable devices, here's some benchmarks of Debian on their Galileo development board.
It's been a while since last hearing anything on the matter of atomic mode-setting and nuclear page-flipping, but the work is still being done for the Linux kernel by Intel engineers.
