For those Intel Linux customers living on the bleeding edge, their open-source graphics driver team has some new code available for testing.
For our first benchmarks from the early Linux 3.9 kernel are some initial Intel graphics benchmarks to look for any changes affecting Sandy Bridge owners with the updated Intel DRM driver.
After talking about it for months with numerous software developers, game studios, and other stakeholders, Ian Romanick of Intel has published his initial specification on GLX_MESA_query_renderer, a new GLX extension (and coming to EGL too) for helping ISVs (and namely games) better understand the system they're running on.
The Intel Mesa DRI driver now supports GL_ARB_texture_multisample. The OpenGL multi-sample textures support is mandated by OpenGL 3.2.
There were huge SNA performance gains on Ironlake over UXA in the most recent testing that happened last night. Curious to see how the SNA 2D acceleration architecture is working for Sandy Bridge graphics hardware, for which it was originally intended, here are some new benchmarks.
Chris Wilson's continued work on the SNA acceleration architecture is really beginning to pay off. In the latest SNA vs. UXA benchmarks for this 2D acceleration back-end to Intel's Linux graphics driver, SNA is delivering some heavy advantages.
Chris Wilson at Intel has begun hand-tuning his SNA acceleration architecture within the Intel X.Org driver in order to take advantage of modern CPU instruction set extensions.
With Mobile World Congress kicking off today, Intel has announced the release of their "CloverTrail+" Atom SoC. The high-end CloverTrail+ chip is the Atom Z2580.
Intel's latest-generation "Ivy Bridge" processors with integrated graphics have already had OpenGL ES 3.0 support when using Mesa 9.1 with recent Linux kernel releases, but now the "Sandy Bridge" processors will advertise OpenGL ES 3.0 support too.
The xf86-video-intel 2.21.3 X.Org driver update is now available with a couple of bug-fixes.
Ahead of Mobile World Congress later this week, Intel and its partners have released the Tizen 2.0 "Magnolia" SDK and its source-code for this open-source mobile Linux platform.
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.
