After yesterday delivering some early Linux 3.15 benchmarks using an Intel Core i7 and AMD Radeon graphics, here's some brief and RC1-stage tests looking at Intel "Haswell" HD Graphics 4600 with the new kernel.
Based upon recent open-source Intel Linux graphics driver patches, the high-end Intel Broadwell "GT3" graphics core will feature dual BSD rings for video decoding.
A few days ago I wrote about Intel adding Cherryview support to their Mesa 3D driver and now waking up this morning they have dropped a huge patch bomb that implements Cherryview Atom support within their DRM kernel driver. We now have a much better understanding for the Cherryview graphics hardware capabilities for when these Atom SoCs begin to ship in some months down the road.
After yesterday's article explaining how-to upgrade the Linux kernel and Mesa/X.Org drivers on Ubuntu 14.04 LTS, I ran some benchmarks from an Intel Atom E3825 Bay Trail system to see whether the newer kernel and Mesa components made a difference for the low-end, low-power hardware compared to what's being shipped by default in Ubuntu 14.04.
At the Intel Developer Forum in Shenzhen, China, Intel has announced Braswell as a new processor to succeed Bay Trail within low-end PCs, laptops, and Chromebooks.
Intel has lined up many exciting open-source graphics driver improvements for their DRM kernel module with the Linux 3.15 release.
Support for the latest Advanced Vector Extensions will be supported by the next Linux kernel release.
For those Intel owners -- namely those with vintage Intel hardware -- the days of using user-space mode-setting (UMS) for the open-source Linux graphics driver are running out.
Cherryview Atom SoCs aren't being released for several months but the first bits of hardware enablement have landed within the open-source Mesa 3D Linux graphics driver. Cherryview with the Cherry Trail platform is the next-generation successor to the wonderful Bay Trail hardware.
Intel was at the Linux Foundation Collaboration Summit this week promoting Tizen's In-Vehicle Infotainment initiatives for having a Linux-based Wayland environment within automobiles.
FBC (Frame-Buffer Compression) support within Intel's DRM graphics driver for Linux can lead to power-savings, but it still isn't turned on by default.
A series of commits hitting Mesa's mainline Git this afternoon offer up some multi-sample anti-aliasing (MSAA) improvements for the Intel open-source graphics driver.
While there have been pre-releases of the xf86-video-intel 3.0 X.Org driver going back to last September, it's still not ready to be released, but a new feature update was made available.
Intel Linux developers have enabled EWA Anisotropic Filtering support within their Mesa 3D driver after discovering their classic AF support might have not been working.
Intel's Haihao Xiang has announced the VA-API 1.3.0 pre1 release. The big theme of VA-API 1.3 is VP8 and Broadwell support.
Intel developers have announced the release of intel-gpu-tools 1.6, for developers and others testing Intel's Linux graphics driver stack.
Intel Mesa developers have added support to their open-source Mesa Linux graphics driver for the GL_INTEL_performance_query extension, which is yet another OpenGL extension exposing performance diagnostic information.
For those curious about the performance of Intel's "Quark" x86 SoC for very low-power applications, including wearable devices, here's some benchmarks of Debian on their Galileo development board.
It's been a while since last hearing anything on the matter of atomic mode-setting and nuclear page-flipping, but the work is still being done for the Linux kernel by Intel engineers.
Intel developers of the Open-Source Technology Center are working on Dynamic Refresh Rate Switching (DRRS) support for Linux.
While the Linux 3.15 kernel merge window won't be open for a few more weeks, Intel has already queued up another batch of DRM graphics driver updates for this next major kernel version.
For distribution vendors or those fortunate to have early access to Intel's forthcoming Broadwell processors, there's a temporary DRM kernel driver branch that provides new features and changes over what's currently found in the upstream Linux kernel or the drm-intel development branch.
The "ILO" Gallium3D driver that is an alternative open-source Intel Linux HD Graphics driver built around Gallium3D, continues being refined.
The Intel Mesa driver now has working support for the performance-boosting HiZ feature with next-generation Broadwell processors and their much-improved HD Graphics.
It was just yesterday I was writing about improvements being made to Beignet, Intel's open-source OpenCL implementation for their Linux graphics stack, while today there's been the surprise release of Beignet 0.8.
Intel's Beignet open-source OpenCL implementation for their Linux graphics driver now switches to LLVM/Clang 3.5 as its preferred version.
The xf86-video-intel 2.99.910 driver was released today as the latest X.Org 3.0 pre-release DDX.
Well, it turns out the open-source Intel Linux graphics driver developers are no longer interested in having an LLVM back-end for their graphics driver.
While the Linux 3.14-rc1 kernel is less than one week old, Intel developers are already hard at work on open-source DRM graphics driver improvements that will not land until Linux 3.15.
