The Intel DRM graphics driver will feature a number of user-facing improvements within the Linux 3.9 kernel.
Intel HD 2500/4000 graphics on "Ivy Bridge" processors now officially support OpenGL ES 3.0 per the Khronos specification. Intel received early word that their conformance results have been certified.
The Intel 2.21 X.Org driver is only one week old, but Chris Wilson of Intel's Open-Source Technology Center is back to his intense work on frequent yet noteworthy point releases to this open-source graphics driver.
Intel has begun releasing patches for supporting their Wellsburg chipset within the Linux kernel.
Intel's work on kernel mode-setting locking has been pulled into the drm-next repository for merging into the Linux 3.9 kernel as one of several open-source Linux graphics driver changes for this next kernel release.
Daniel Vetter of Intel's Open-Source Technology Center talked this weekend about recent and future improvements being worked on for the company's open-source DRM graphics kernel driver.
Last summer the open-source Intel Linux graphics driver reached the milestone of being officially OpenGL ES 2.0 conformant with the Khronos specification. Intel has now submitted their OpenGL ES 3.0 results to the Khronos Group for validation with Ivy Bridge hardware and the Mesa 9.1 branch in hopes of being one of the first driver implementations to be officially GLES 3.0 conformant.
Dirk Brandewie has published a new P-state driver for Intel Core CPUs on Linux. This new cpufreq performance state scaling driver initially is supporting just Sandy Bridge processors but will be expanded to handle other Intel hardware.
This weekend in Brussels I heard about the state of Intel's initiative for migrating to an LLVM-based shader compiler for their open-source Mesa 3D driver to replace their existing custom compiler embedded within the driver. Unfortunately, the state of this LLVM-based compiler is rather meager.
It was revealed today at the Free Open-Source Developers' European Meeting (FOSDEM) that Intel through their Open-Source Technology Center is currently over two dozen full-time graphics driver developers. They're also looking to hiring more developers.
When it comes to Intel hardware enablement on Linux, most of what's been talked about lately is the Haswell support for the soon-to-be-launched processors. However, the Valley View support on Linux is still being worked on for the next-generation Atom SoC that boasts in-house Intel HD graphics.
After releasing nearly two dozen point releases in the xf86-video-intel 2.20.x series, the xf86-video-intel 2.21 X.Org driver was christened on Friday. There's a few notable additions to this 2.21 Intel open-source driver update for Intel hardware Linux customers.
TianoCore, the open-source UEFI implementation backed by Intel that was just talked about in Google Pushes "Project PIANO" Into Coreboot, already has support for Intel's yet-to-be-released Broadwell and Bay Trail processors.
Another patch landed in mainline Mesa today that's capable of providing a small performance boost for some OpenGL workloads with Intel's open-source Linux graphics driver.
Zhang Rui of Intel is working on supporting the PM_SUSPEND_FREEZE power management suspend state for their open-source Linux graphics driver. This PM suspend state has some benefits over other current power states but also some shortcomings.
Chris Wilson of Intel's Open-Source Technology Center has shared some early performance results of an experimental multi-threaded software rasterizer for Cairo's image back-end that can accommodate multi-threading.
Intel will be introducing their Haswell processors in the coming months. If using the Linux 3.8 kernel, GCC 4.7/4.8, Mesa 9.1, and other recent open-source Linux packages, you should be mostly set for experiencing the full benefits of the Ivy Bridge successor. However, there's still a few pieces of Haswell's Linux support still being worked out.
Intel has begun publishing Linux kernel patches to enable hardware support for their next-generation Avoton System-on-a-Chip. Avoton will be found in future low-power Atom offerings.
SNA, Intel's newest acceleration architecture for their open-source X.Org graphics driver, continues to receive improvements on a near daily basis.
Chris Wilson has shared his testing experience of Cairo with NVIDIA ION hardware on the open-source Nouveau driver and the closed-source NVIDIA blob. In certain situations, the Cairo performance does better with Nouveau than the official NVIDIA Linux driver.
In addition to the Intel driver now always enabling floating-point textures, a patented feature but something that's required for GL3 compliance, the Intel DRI driver is set to play better with S3TC, the also patent-troubled but widely-used S3 Texture Compression.
Intel's Mesa DRI driver now is unconditionally enabling floating-point textures. Up to this point, the floating-point textures feature of GL3 hasn't been enabled by default due to patent worries.
On Sunday was the release of the xf86-video-intel 2.20.19 DDX driver. This is the 19th point release in the long-standing Intel X.Org 2.20 series that's been largely led by Chris Wilson out of Intel OTC.
Intel's Mesa DRI driver received a new patch this weekend that's capable of enhancing the open-source graphics driver's performance for some OpenGL games.
With we are only about half-way through the development of the Linux 3.8 kernel, there's already exciting features beginning to enter the development spotlight for Linux 3.9. One of the features coming to the Linux 3.9 kernel will be grand changes to the very common "HDA Intel" audio codec drivers.
Last week I wrote about Beignet as Intel's OpenCL Linux implementation for "Ivy Bridge" hardware. While the code was recently open-sourced, the future direction of this project is unknown.
Chris Wilson of Intel OTC has released yet another X.Org driver update in the xf86-video-intel 2.20 series. This latest DDX update does bring rendering improvements plus fixes for various performance regressions.
For the open-source Radeon and Nouveau graphics drivers on Linux, OpenCL/GPGPU support has been implemented via the "Clover" OpenCL state tracker with the Radeon/Nouveau drivers built atop the Gallium3D driver architecture. While Intel's latest hardware supports OpenCL with its graphics core, their open-source Linux driver has lacked any support, but that is changing.
For developers looking to get into Linux graphics driver programming or just wanting to know how Intel's Graphics Execution Manager (GEM) works within the Linux kernel, here's a guide.
Ubuntu developers are still deciding whether they will enable support for the Intel SNA "Sandy Bridge New Acceleration" architecture within Ubuntu 13.04, the next release of the Linux operating system.
