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.
NVIDIA's proprietary driver and the open-source Gallium3D Linux graphics drivers -- namely now the open-source Radeon UVD support -- are using VDPAU as their accelerated video playback API. Meanwhile, Intel still continues to invest heavily in VA-API as their preferred video acceleration API for Linux. An exciting set of 42 patches to improve VA-API was published on Monday.
Curious about the top contributors to the open-source Intel Linux kernel driver, Ben Widawsky of Intel's Open-Source Technology Center did some analysis.
Intel has announced the release of an open-source Linux Thermal Daemon package for Linux. Intel's Linux Thermal Daemon is for monitoring and controlling platform temperatures.
Intel released yesterday the Intel SDK for OpenCL Applications XE 2013. This is an OpenCL SDK for Linux that supports OpenCL 1.2 and all of the latest and greatest Intel hardware.
Just days after landing some OpenGL performance tweaks, Intel's Eric Anholt has committed some more performance optimizations for the Intel i965 Mesa driver.
Ahead of the official Haswell launch in early June, Intel released more details yesterday concerning the expected graphics performance out of the Ivy Bridge successor.
At least three commits seeking to improve the performance of Intel's open-source 3D/OpenGL Mesa driver were merged on Monday.
While there's been talk recently of defaulting the Intel i914/i945 hardware support to using Gallium3D rather than the longstanding classic i915 Mesa DRI driver, some new features were just introduced into the i915 classic world.
Support for the "reserved" Haswell PCI IDs were added to the Intel Linux graphics driver.
The modern Gallium3D graphics driver for supporting Intel Sandy Bridge "Gen6" and Ivy Bridge "Gen7" graphics has been merged into mainline Mesa!
The GStreamer VA-API plug-ins have been updated with support for the GStreamer 1.0.x API.
The Linux 3.10 kernel that's soon entering development will feature a fair number of graphics driver changes.
Intel's Integrated Performance Primitives (IPP) and their Math Kernel Library (MKL) provide for very fast math operations with modern processors.
In the discussion about mainlining the new Intel Gallium3D driver for Sandy Bridge and Ivy Bridge processors, the long-standing i915 Gallium3D driver for older Intel hardware was brought out. It turns out that this driver might replace the classic i915 Intel driver as the new default.
Intel's Open-Source Technology Center has done their inaugural release of NumaTOP.
Intel has now officially enabled support for their next-generation Bay Trail (a.k.a. Valley View) platform within their open-source i965 Mesa graphics driver.
Yesterday was marked by the first release of Beignet, an open-source Linux OpenCL solution for Intel Ivy Bridge hardware, however it has drawn criticism by open-source developers.
Harris Beach is Intel's compelling Software Development Platform/Vehicle for Haswell in the form of an ultra-thin ultrabook.
While Intel has previously shipped its OpenCL SDK for Linux and Windows, this SDK is closed-source and on Linux was limited to compute support only on the processor rather than any graphics support with Ivy Bridge and newer hardware. Fortunately, Intel has finally managed to put out a first release of Beignet, an open-source Linux project that supports OpenCL.
For several months Intel developers have been working on a tool that allows for source-to-source automated conversions of C++ code into C++11 compliant code.
If running the latest stable components powering the Intel Linux graphics driver (namely the Linux kernel, Mesa, and xf86-video-intel), the open-source graphics support for the forthcoming Haswell processors should be in fairly good shape. However, like Sandy Bridge and Ivy Bridge, it will take some time before the Linux graphics driver is fully-optimized. Fortunately, there's another newly-enabled Haswell feature to report within Mesa.
The xf86-video-intel 2.21.6 driver has been released, which among other changes, supports kernel mode-setting on OpenBSD.
Introduced last month was the ability to overclock Intel graphics under Linux while presented hours ago is a new Intel Linux kernel driver patch to provide better GPU overclocking support.
Intel has introduced a "Running Average Power Limit" Linux kernel driver for their platforms.
For those wondering whether Intel "Ivy Bridge" hardware is still being made faster with each succeeding Linux kernel release, here are benchmarks from an Intel Ultrabook looking at the Ivy Bridge performance on recent kernel releases going up to the yet-to-be-out Linux 3.9 kernel.
Open-source Intel developers have advanced their OpenGL geometry shaders work for Mesa, namely for the Intel DRI driver, and call it "substantial progress and definitely a reason to celebrate." This important GL3 feature is nearing a working state but there's still some work ahead before it will be merged.
While Left 4 Dead 2 still hasn't been released to the general Linux gaming public, it's coming. Intel open-source developers are also continuing to work on optimizing the Source Engine game for their Linux graphics driver.
