With the Linux 3.11-rc1 release, it's time now at Phoronix to start benchmarking the Linux 3.11 kernel. The first tests to run over the weekend were of Intel Ivy Bridge graphics, where a few regressions were spotted.
Intel's Ironlake hardware may be very old and not nearly as nice as the latest generation Haswell parts, but shipped today was a new patch-set for implementing hardware context support.
Chris Wilson has put out another speedy X.Org Intel graphics driver release, this time bumping it to version 2.21.12.
Intel Open-Source Technology Center developers are currently working on another feature of Intel's latest-generation Haswell architecture not currently exposed by their open-source Linux graphics driver.
Ian Romanick of Intel who generally has been serving as the release manager of new Mesa releases, has announced some planned changes for releasing Mesa 3D drivers.
For benefiting embedded Linux developers with greater system performance and power efficiency, Intel has ported their System Studio Extended software to Linux.
Chris Wilson has released yet another xf86-video-intel 2.21.x driver point release.
Intel released version 1.2.0 of libva and libva-intel-driver over the night. The updated Video Acceleration API (VA-API) now has support for MPEG-2 encoding along with new H.264 profile encoding API support.
Intel's Chris Wilson has done a Saturday morning release of the xf86-video-intel 2.21.10 driver to get out more performance tweaks and regression fixes.
Since the Computex launch of Intel's much anticipated Haswell processors at the beginning of the month, there's been much Linux coverage on Phoronix concerning the compatibility and performance of these new Intel processors from both the processing and graphics sides. Here's a summary of all of our discoveries and findings over the past few weeks.
With the extensive coverage on Phoronix this month of Intel's new Haswell processors on Linux, many articles have shown that when using the latest components (e.g. Linux 3.10 kernel and Mesa 9.2) that the OpenGL performance is a whole lot faster. But are these changes specific to Haswell or benefit Intel's driver as a whole? In this article are new benchmarks from an older Intel "Sandy Bridge" system with HD 3000 graphics to see whether the performance there is also improving with the latest Linux code.
With new code going into Mesa on a daily basis, here's the very latest benchmarks comparing the state of stable Mesa 9.1.3 against the Mesa 9.2 development code with all of the performance optimizations it brings to the Intel DRI driver for the latest-generation Haswell graphics hardware.
Intel's Daniel Vetter is attempting for the Intel DRM graphics driver to remove support for its FBDEV frame-buffer layer with a new patch-set entitled "fbdev no more!", but will this finally usher in the killing of the Linux kernel's FBDEV subsystem?
The "Ilo" open-source driver that provides unofficial Intel Gallium3D graphics support for Sandy Bridge and Ivy Bridge graphics cores on Linux now is advertising GLSL 1.40 compliance. The GL Shading Language update comes after landing UBO and TBO support.
For the past week on Phoronix since the public debut of Intel's Haswell processors there has been a lot of coverage. The CPU performance is generally great but the Haswell Linux graphics support is still a work-in-progress even though its performance has already evolved a lot. This Sunday are some extra Core i7 4770K benchmarks.
While the Linux 3.10 kernel hasn't even been released yet, the Intel Open-Source Technology Center developers working on the Linux graphics stack already have a lot of worthwhile changes heading into the Linux 3.11 kernel.
Chris Wilson of Intel's Open-Source Technology Center is back to pushing out xf86-video-intel driver updates at an expedited rate. Rather than the new releases being about advancing the SNA acceleration architecture or new features, the past few have been about correcting regressions and other bugs.
A new feature being worked on for the Intel DRM Linux kernel graphics driver is IPS. Short for Intermediate Pixel Storage, this feature should allow modern Intel HD graphics cores to let the CPU enter deeper PC states to increase power-savings.
With the testing of the very latest Intel X.Org graphics driver, the SNA 2D acceleration back-end for the Ivy Bridge graphics is now the clear-cut winner for the Linux desktop over using the default UXA back-end.
Just one week after the Intel X.Org driver was updated with support for all known Haswell variants and introducing some new copy-on-write support for cloning pixmaps, a new release has been warranted.
At the Tizen conference this week in San Francisco, Intel showed off an Intel Ultrabook running their next-generation Tizen 3.0 platform that's using a shell/desktop derived from GNOME 3.x.
With the public launch of Intel's beautiful Haswell CPU being imminent, Intel has released the xf86-video-intel 2.21.7 DDX driver that should support all of the Haswell PCI IDs.
On Friday there was the controversial news about the Linux "ondemand" cpufreq governor no longer being fit for best performance and power-savings on modern processors. Fortunately, for better handling the CPU frequency stage changes on modern Intel CPUs, Intel recently introduced the new P-State kernel driver.
While it's not the default Linux graphics driver for Sandy Bridge or Ivy Bridge hardware, the "ilo" independently-developed Gallium3D driver for modern Intel graphics hardware continues to be developed.
Earlier this month I delivered Radeon DRM driver benchmarks and Nouveau DRM driver benchmarks from the in-development Linux 3.10 kernel. Being published this Friday evening are now Intel Ivy Bridge graphics benchmarks from the Linux 3.10 kernel compared to the earlier releases going back to Linux 3.5.
