Intel OTC developers continue to hack on the support for enabling next-generation Haswell processors with integrated graphics under Linux.
Eric Anholt of Intel's Open-Source Technology Center had a few things to say yesterday at the 2012 GStreamer Conference about their open-source Linux graphics driver stack. Intel is aiming to hit hard on performance improvements and one of the interesting statements made is that they're now looking at moving to an LLVM-based shader compiler for a big performance win. Left 4 Dead 2 running on Mesa was also shown.
Version 1.3 of intel-gpu-tools was released with "too much stuff changed", well, with 177 changes compared to the earlier release of this open-source GPU tools package for Intel hardware.
Following the recent Intel HD 2500 Ivy Bridge Linux graphics benchmarks, here's some more numbers that were recently collected when benchmarking the latest Linux graphics code with the Intel HD 2000/3000/4000 graphics cores when clocking the rest of the CPU to a common speed.
Chris Wilson has released yet another driver update in the xf86-video-intel 2.20 series.
Intel's Mesa driver for Sandy Bridge and Ivy Bridge graphics are now officially compliant against the Khronos OpenGL ES 2.0 specification.
Version 2.1 of PowerTOP has been released with improvements for not only Intel hardware running Linux but ARM assets as well.
A set of 58 patches have been published against the Intel Linux DRM kernel driver that completely rewrites the mode-setting code for this open-source Linux graphics driver.
An extensive set of patches have been published that allow the Linux kernel to be built with GCC's LTO (Link-Time Optimization) support for generating a faster Linux kernel binary but at the cost of much greater compile times.
In addition to running 2D benchmarks, Intel's Chris Wilson has been busy pushing out point releases to the xf86-video-intel 2.20 series. Generally we don't see more than one or two point releases per cycle, but now we're already up to four.
GLAMOR 0.5 was released earlier this month and testing has revealed that this 2D-Over-OpenGL acceleration library is now faster but still comes up short compared to other 2D driver implementations.
An Intel engineer has proposed introducing a power saving schema for CFS, the Linux kernel's default scheduler. Code hasn't been presented yet, but there's lots of discussion about this topic to improve the power efficiency of the Linux kernel scheduler.
Coming out of SIGGRAPH 2012 is a new branch of Mesa from Intel's Open-Source Technology Center that's working on full open-source OpenGL ES 3.0 support for Intel HD hardware.
Ian Romanick has published a set of 14 new patches today as he prepares support within Mesa for creating OpenGL 3.1 core contexts, as open-source OpenGL 3.1 support finally inches further.
Thanks to patches surfacing on public mailing lists on Monday that continue work on the open-source enablement of Intel Haswell graphics under Linux, we have a look at the different variants of Haswell. Somewhat surprising is that there's 36 different IDs representing the next-generation Haswell products with different flavors of integrated graphics.
Intel's open-source hardware enablement under Linux of next year's Haswell architecture continues. New HDMI audio patches have been published while the DisplayPort audio patches are still forthcoming.
Chris Wilson of Intel OTC put out another point release to the xf86-video-intel 2.20.x DDX driver on Saturday.
Aside from the normal desktop shell for Wayland's Weston reference compositor, open-source Intel developers have resurrected work on a tablet-oriented shell for this fledging display server.
For the past several months there's been open-source driver development activities within the Linux kernel and Mesa library as it pertains to Haswell, the 2013 Intel micro-architecture to succeed this year's successful Ivy Bridge platform. There's xf86-video-intel DDX driver commits landing today pertaining to Haswell.
Intel's Video Acceleration API (VA-API) has seen updates to its core library as well as to the Intel-specific VA-API Intel driver.
Following the success of Ivy Bridge and their continued open-source contributions, Intel graphics continue to gain market-share on the Linux desktop.
The xf86-video-intel driver has picked up thousands of lines of new code today with the integration of a BRW assembler in order to compile shader programs on the fly and to remove inefficiencies and mistakes from current Intel shaders.
A patch to mainline Mesa yesterday from Intel has resulted in a ~7% performance boost for Sandy Bridge "GT2" graphics when running the video stress test for Valve's Counter-Strike: Source.
Keith Packard has been playing around with LLC controls on Sandy Bridge to see how caching back-buffers affect application performance with the Intel Linux graphics driver. He has provided an Intel DRM driver patch for those wishing to experiment.
Another one of the pulls going into the Linux 3.6 kernel this week is the ACPI and power management updates courtesy of Intel. The two prominent changes for this next Linux kernel release is a rewrite of the "turbostat" tool and the "intel_idle" CPU idle driver now supports Ivy Bridge processors.
Intel has released a new open-source X.Org driver for their Intel graphics since it was only just discovered that the Ivy Bridge GT1 "HD 2500" graphics were busted.
Intel has released their 12.07 Linux graphics driver package.
