Yesterday I shared some benchmarks showing Intel Sandy Bridge HD Graphics performance increasing on Linux 3.17 for this several year old architecture. This came as a surprise but the good news is the performance improvements on this new Linux kernel don't stop with OpenGL but extend to CPU performance too.
Connor Abbott, the open-source developer that began contributing to the Lima Linux graphics driver while a high school student, was interning at Intel this summer even before starting college. Over the summer the focus of his Intel Linux internship was focusing on developing a new intermediate representation for Mesa graphics drivers.
The native hardware cpuidle driver for Intel CPUs now supports the upcoming Broadwell processors with Linux 3.17.
Intel passed along word that they've begun shipping their Core M Broadwell-Y chips.
Linux 3.17-rc1 is still about one week away at least, but already two commits of new functionality were reverted from the Intel DRM driver code for Linux 3.17.
While we're still waiting until around the end of the year to see Broadwell processors, Intel's Open-Source Technology Center is already prepping Linux graphics driver code to begin pushing Skylake support into their driver stack.
The Intel DRM graphics driver will feature its usual large amount of changes with the in-development Linux 3.17 kernel.
Chris Wilson announced the release this morning of the xf86-video-intel 2.99.913 driver as the latest development version in the nearly year-long process of releasing xf86-video-intel 3.0.
Intel has introduced BPTC texture compression support to Mesa and specifically their Intel HD Graphics driver along with the Mesa software rasterizer.
Aside from upstream work to the GLAMOR acceleration code itself that's now part of the X.Org Server, Keith Packard has been working on the GLAMOR hook-up for the xf86-video-intel DDX driver.
Intel developers have added support for VP8 video encoding to the open-source Video Acceleration API.
With the Linux 3.16 kernel just being a few weeks away from its debut, Intel's Open-Source Technology Center has out another batch of changes being queued up for drm-next to enter with Linux 3.17.
Intel's Linux open-source crew is toying with aggressive down-clocking for current-generation Bay Trail hardware for greater power-savings and lower heat output.
Beignet, Intel's method of supporting OpenCL compute under open-source Linux on the graphics cores within their modern processors, is out with a very significant release today.
Intel's MIC run-time offload library will likely be added to the GNU Compiler Collection in the very near future.
For what it's worth, the marketing graphics product names for Intel's upcoming Broadwell processors have been revealed.
While the Linux 3.16 kernel is still many weeks away from being released, Intel's Open-Source Technology Center already has some new code for testing that will ultimately end up in Linux 3.17.
For years the open-source Intel Linux graphics driver developers have been working on frame-buffer compression (FBC) support but never it's worked out quite good enough to turn it on by default in full. Frame-buffer compression has the ability to reduce power consumption for those using Intel HD Graphics while reducing the amount of memory bandwidth used for screen refreshes. Now though the Intel DRM FBC code has been re-worked and perhaps this time it will be flipped on by default.
Version 1.3.2 of Intel's VA-API driver for open-source video encode/decode using modern Intel HD Graphics GPUs has been released.
Earlier this week I published the first Linux review of the Intel Core i7 4790K "Devil's Canyon" processor that's a refreshed Haswell CPU with 4GHz base frequency and 4.4GHz Turbo.
Last month I wrote about how the Intel 3.0 X.Org driver has been in development for the better part of a year with no indications of an imminent release. The xf86-video-intel 3.0 release still hasn't happened, but a new development release is out and it packs even more features into this open-source Linux display driver.
Intel has lined up many graphics driver changes for Linux 3.16 and if you haven't been up to speed with all of our Linux 3.16 coverage, here's a concise overview of the Intel i915 DRM graphics driver changes for this next kernel version.
For those wishing to better understand more of the internal workings of Intel's i915 DRM driver that provides the kernel-side portion to their Linux graphics driver, Ben Widawsky of the Intel Open-Source Technology Center has written a great blog post that's the start of the series documenting the Global GTT.
For developers and debug-willing Linux enthusiasts, the Intel GPU Tools 1.7 open-source release is now available.
The Linux graphics developers within Intel's Open-Source Technology Center have already prepared a fresh batch of changes that will land with the Linux 3.17 kernel -- even though the Linux 3.15 kernel hasn't been released yet and the Linux 3.16 kernel merge window opened early.
For many months now Intel has been working on RAPL support within the Linux kernel as part of their power-capping framework as a power feature for Intel hardware on Linux.
For those interested in DisplayPort MST support on Linux to support the specification's multi-stream transport ability, there is now a revised patch-set providing this support.
Intel has published a new Linux kernel patch-set that adds Quick Assist Technology support to Linux along with a driver to handle their DH895xxC hardware accelerator. This is a new chip for trying to accelerate cryptography and data compression tasks.
Intel will begin shipping the Core i7 4790K "Devil's Canyon" processor this month and thanks to Computex now getting underway we're able to publicly talk about this high-performance chip.
To complement the recent ACPI CPUfreq vs. Intel P-State Scaling With Linux 3.15 testing that was done using an Intel Core i7 Ivy Bridge Extreme Edition system, here's some similar tests done using a low-power Intel Celeron N2820 "Bay Trail" SoC within the Intel NUC.
