Following the benchmarks I posted this morning showing Intel Haswell graphics having some OpenGL slowdowns with the newer Mesa graphics driver code, I tested a sharply different Haswell system to see if the performance differential was also to be found on this Intel ultrabook with Iris Graphics 5100...
As I wrote about when Intel launched the Z97 chipset earlier this month in preparation for the Haswell Refresh and Broadwell CPUs, the Linux compatibility for the new motherboards powered by the Intel 9-Series chipsets should be in good shape. One of the motherboards I have been testing since then is the Gigabyte Z97-HD3.
The 2014 release of Intel's OpenCL SDK for Windows and Linux is now available.
Intel has released a new version of their open-source PowerTOP utility for Linux systems to diagnose power consumption issues and make improvements to power management by individually analyzing the system's current power settings.
We're anxious to test out Intel's next-generation Broadwell processors but it doesn't look like they'll be out in time for "back to school" shopping but should certainly arrive in time for the holidays.
We're still a few weeks away from the release of the Linux 3.15 kernel but open-source Intel developers have already sent in another drm-next pull request to land more of their kernel graphics driver changes for Linux 3.16.
Intel this week has released their Intel Graphics Installer 1.0.5 for Linux, which ships their 2014Q1 open-source graphics driver stack. Supported with this quarterly update is now also Ubuntu 14.04 LTS while the other primary target, Fedora, is still obviously at version 20.
Today the NDA clears covering Intel's new Z97 and H97 chipsets, which are targeted for the Haswell-Refresh CPUs along with Broadwell CPUs later in the year.
Last month Intel announced a new, fan-less Intel NUC Kit, the DE3815TYKHE and it featured an Intel Atom E3815 SoC. While at first I immediately planned to buy one, now that they're available, I've changed my purchase order instead to another DN2820FYKH NUC Kit for Linux usage.
Daniel Vetter of Intel's Open-Source Technology Center is presenting this week at LinuxTag 2014 about the state of their Linux kernel graphics driver.
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.
