Intel OTC has published a set of 21 new patches for "Haswell" hardware enablement of their graphics core with their open-source Linux driver. With this latest round of patches, Intel is already saying that the Haswell Linux graphics support is nearly on par with Ivy Bridge when it comes to the kernel driver.
Another Intel DRM pull request was submitted this morning for driver changes that will ultimately land in the Linux 3.6 kernel. With these latest open-source Intel driver changes, some new details are revealed about Intel's Valley View -- their next-generation Atom SoC that sports Ivy Bridge class graphics rather than any PowerVR cruft.
A second round of patches have emerged for the open-source Intel Linux graphics driver to support atomic mode-setting with the kernel.
The Intel "i915g" Gallium3D driver now implements sRGB textures support, but this is basically the end of the road for new features.
Intel quietly pushed out their "Ivy Bridge" graphics programming documentation and register specifications on Friday. This Ivy Bridge graphics core programming documentation spans 17 files spread across three volumes and 2,468 pages of technical details concerning their latest-generation graphics.
It looks like for the Linux 3.6 kernel there will finally be D3 Cold power-savings support for PCI Express devices under Linux.
While Intel's original GMA500 "Poulsbo" hardware is now more than four years old, this Intel Atom platform with PowerVR graphics continues to be a bloody mess under Linux.
For those that didn't hear yet, Intel's getting ready to ship the Larrabee-derived "Knights Corner" co-processors and they will be marketed under the name of Xeon Phi.
Intel has published open-source code for supporting the Knights Corner micro-architecture on Linux.
For months already Intel has been working on Haswell enablement under Linux. While the Intel Haswell CPUs are still a year out from shipping, the graphics code is already being tackled quite extensively. This morning we're now seeing the first signs of Intel Haswell audio support.
While the Linux 3.5 kernel is still weeks away from being released (we're not even at 3.5-rc3 yet!), the Intel DRM graphics driver changes have already begun to queue up for the Linux 3.6 kernel.
In making way for some interesting Linux benchmarks coming up, here's some of the results from last month that haven't yet been published. This is a brief look at Mesa 8.0 vs. 8.1-devel Git for Intel Ivy Bridge hardware.
Ubuntu developers are looking at enabling support for Intel SNA acceleration within the open-source graphics driver for the Ubuntu 12.10 release.
While not yet the default means of 2D acceleration for the Intel driver, the SNA architecture is even reportedly performing well -- better than UXA -- for the old Intel 855.
Intel continues to work on Linux kernel patches for ZPODD support.
Intel's Open-Source Technology Center team has published a massive set of 43 patches for "Fastboot" support with their open-source Linux graphics driver.
Aside from Intel's Open-Source Technology Center finally releasing PowerTOP 2.0, developers at the company have also finally released a stable version of another one of their initiatives: ConnMan.
Mesa is finally getting closer to properly supporting MSAA, a.k.a. Multi-Sample Anti-Aliasing, but for now this is just Intel Sandy Bridge supported.
As a word of caution for anyone that was hoping Thunderbolt (a.k.a. Light Peak) was in good shape for Linux, the Intel technology doesn't appear to be quite ready yet.
There's many more Ivy Bridge Linux tests coming out in the next few weeks, but here's some new results today for the Core i7 3770K processor looking at the overclocking results and effects of Turbo Boost and Hyper Threading.
The xf86-video-intel 2.19.0 DDX driver was released this week to provide more stability fixes for UXA acceleration as well as provide support for the Intel Ivy Bridge GT2 server chip.
For those interested in Tizen, the latest Intel Linux distribution effort succeeding Moblin and MeeGo, version 1.0 "Larkspur" is now available with an SDK and the source-code is out for developers.
Aside from all the Linux gaming news this week, the past few days were also particularly exciting due to Intel's launch of the much-anticipated Ivy Bridge processor line-up. There were launch-day Linux benchmarks of the Intel Core i7 3770K on Phoronix plus many more articles are currently in the publishing pipeline.
Zhigang Gong on the behalf of the Intel China team released Glamor 0.4 as the latest work on the unique Glamor acceleration architecture for the Intel X.Org driver.
A few interesting patch-sets were published today concerning Wayland.
Intel's Ian Romanick has made progress in his long side-project of compiling OpenGL assembly shaders to GLSL IR. He's now up to the point of being able to run the Doom 3 binaries with this conversion work for Mesa.
While we're still several weeks out from even seeing the release of the Linux 3.4 kernel, Intel's developers working on their open-source Linux graphics driver stack have already begun planning their merge of changes for the Linux 3.5 kernel.
While Intel has a lot of interesting work going on right now within their Linux kernel DRM driver and elsewhere within their open-source graphics stack, operating systems like OpenIndiana/Illumos and FreeBSD are still catching up, but they're still a ways off.
A mailing list message this morning raises the possibility that Intel's open-source graphics developers could soon be working on GPGPU/OpenCL support.
Intel's open-source Linux graphics developers remain confident that we're likely to the final chapter of the lets-try-rc6-by-default-one-more-time saga. The RC6 power-savings feature for Sandy Bridge graphics hardware should hopefully be -- finally -- sane to keep enabled by default.
