A patch-set has been published that provides Dynamic Refresh Rate Switching (DRRS) support for Intel's DRM Linux graphics driver.
Patches were published last week that enable support for the Intel Processor Trace extension within the Linux kernel's perf sub-system.
A few days back I wrote about an Intel Linux developer finding a 50 Watt power regression within the kernel since the 3.10 release. At first it looked like it might be easily solved, but the issue is still being investigated and Intel hardware engineers are now getting involved in the matter.
A set of Intel developers have worked out a new set of AVX and AVX2 routines for the Linux kernel to enhance additional crypto functionality for better performance.
Published in early November was the initial Intel Broadwell graphics hardware support that was merged into the mainline Linux 3.13 kernel. This afternoon, initial Intel Broadwell support has been merged into the xf86-video-intel X.Org graphics driver.
An Intel Linux kernel developer has discovered that since the Linux 3.10 kernel one of his powerful Xeon-based systems is going through 50 Watts more energy while idling than on pre-3.10 kernels. This power regression could affect smaller systems too, but fortunately the issue has been bisected and an investigation is in process.
Ben Widawsky has been working on PPGTT support for a while now with the open-source Intel Linux graphics driver and he's now called upon for the support to be pulled into the next kernel release.
Yesterday I ended up buying a new Intel ultrabook for Linux testing at Phoronix. Here's the hardware that will soon be featured in some new Linux benchmarks, plus my reasoning for going with this ultrabook and other thoughts on some of the laptops/ultrabooks this holiday season.
Intel's Open-Source Technology Center has prepared a set of thirteen patches against Zlib to sharply improve the deflate performance.
Intel's Windows OpenGL driver continues to make progress in a more steadfast manner than the open-source Intel Linux graphics driver. The latest achievement for the Intel Windows driver is OpenGL 4.2 compliance for Haswell.
A few days ago Intel implemented GL_AMD_performance_monitor support within their open-source DRI graphics driver and now they have implemented support for another important modern OpenGL extension that happens to have been developed by AMD.
Intel Linux developers are still working on a Haswell run-time power management feature for their open-source graphics driver.
While Intel "Sandy Bridge" graphics hardware is capable of full GL3 support, the open-source Intel Mesa graphics driver is still limiting it to OpenGL 3.1 compliance.
Intel's OpenGL Mesa driver has added support for the AMD_performance_monitor extension to expose more graphics system performance characteristics.
Carl Worth at Intel has announced the release of Mesa 9.2.3
The xf86-video-intel 3.0 driver is still on the way and Intel OTC's Chris Wilson has put out today its latest development release that has stability fixes, including further TearFree updates.
Intel's Open-Source Technology Center has done their first release of Ozone-Wayland, the new component that allows Google's Chromium web-browser to work natively on Wayland without any dependence on X.Org. Fedora and Ubuntu binaries are currently available.
For those with Intel graphics on Linux and are interested in the lower-level workings of the hardware or in testing out new code, Intel's Open-Source Technology Center has released a new version of their GPU Tools package.
Last month I wrote about the road being clear for Intel Cilk Plus landing in GCC and as of a few days ago the run-time library and Cilk spawn/sync support was finally merged.
Earlier today I wrote at length about Intel open-sourcing their Broadwell graphics driver code for Linux support months ahead of the 2014 processor debut. Besides the kernel changes queued up for the Linux 3.13 kernel, the Broadwell OpenGL/3D driver support has turned up in a Mesa Git branch.
Yesterday I outlined the AMD Radeon DRM graphics changes that were queued up for the Linux 3.13 kernel that will soon be officially under development. Now for Intel Linux customers there's an overview of the Intel DRM graphics driver changes for this next kernel release cycle.
With Mesa 10.0 planned for release this month and to be branched from Git master this coming week, a number of exciting commits landed on Friday for Intel's open-source Mesa DRI graphics driver.
As hopefully a sign that Intel will soon be publishing their open-source graphics driver code for next year's Broadwell platform, new patches emerged today for supporting multiple power wells to be present on "upcoming hardware" out of Intel.
Since last week's release of OS X 10.9 "Mavericks", I've begun benchmarking my few Apple systems to see how the performance compares over OS X 10.8. In this article are our first benchmarks of OS X Mavericks final as we look at how the performance changes for a Haswell-based 2013 MacBook Air.
A set of Linux kernel patches have been proposed to improve vblank time-stamping by the Linux DRM/KMS drivers. This is able to improve the precision and reliability of the KMS drivers of time-stamps for handing VBlank support.
Ahead of the Linux 3.13 kernel merge window in a few weeks time, Intel is seeking review of a proposed Power Supply Charging Framework for the Linux kernel.
Chris Wilson of Intel this morning released an updated xf86-video-intel X.Org driver. With this latest 3.0 pre-release comes support for TearFree on transformed outputs. There's also been other changes.
With our investigation into the potentially large performance changes in the Linux 3.12 kernel due to a CPUfreq change that can vastly improve the 3.12 kernel Radeon graphics performance, I also checked for Core i7 Haswell performance changes with this latest kernel. However, if using a low-end Core i3 CPU is the performance any different for 3.12? Here's test results.
Most often when running Intel Linux graphics benchmarks these days we're using Haswell hardware since that's where the most exciting developments are now happening with it being the latest-generation Intel products. However, we routinely go back and test older generations of hardware. With it having been a while since last running Mesa benchmarks with Ivy Bridge, especially now this week Mesa 10.0 receiving OpenGL 3.3 support, it's time for some new benchmarks.
Eric Anholt at Intel has a new Mesa GLSL patch to add a new pass for their compiler that decreases the number of instructions and can result in performance improvements.
