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.
With a week having passed since the release of xf86-video-intel 2.20, Chris Wilson has today issued the driver's first point release to take care of some critical bugs.
Chris Wilson is now in effective control of the xf86-video-intel open-source graphics driver with being responsible for nearly all of its development activity. Plus there's some other interesting statistics to share.
Intel's Linux graphics driver is finally onto supporting 8x multi-sample anti-aliasing (MSAA), assuming you're using the latest-generation Ivy Bridge graphics hardware.
Chris Wilson released the xf86-video-intel 2.20 driver on Sunday, which brings SNA acceleration to the masses.
Intel has provided Linux kernel support for PCI Express Non-Transparent Bridges (NTB). PCI-E NTB allows for interconnecting multiple systems using PCI Express.
Daniel Vetter's re-work of the Intel DRM driver mode-setting code has now expanded to 81 patches in size.
The xf86-video-intel driver, the open-source X.Org driver for Intel's graphics processors on Linux, is now being built with Sandy Bridge New Acceleration (SNA acceleration) by default. This means of acceleration is generally much faster than the long-standing UXA mode for both old and new hardware.
Kenneth Graunke committed the i965 Mesa driver hardware context support patch on Tuesday. Meanwhile, the Radeon Gallium3D driver has also seen improvements.
Several Phoronix readers have written in that Eugeni Dodonov, a former Mandriva developer who since last year has been working for the Intel Open-Source Technology Center on their Linux graphics driver, lost his life this weekend.
The latest noteworthy patch-set coming out of the Intel Open-Source Technology Center is Mesa support for CMS MSAA for Ivy Bridge hardware.
Daniel Vetter has pushed out new -next and -testing branches for Intel's open-source Linux graphics DRM driver with a few highlights worth noting.
