NVIDIA's 2016 Tegra SoC Is Looking Even More Interesting

Filed under
Graphics/Benchmarks

At NVIDIA's CES press conference last night they announced the DRIVE PX2 as a "in-car super-computer" that's "as powerful as 150 MacBook Pros", while this SC is powered by a yet-to-be-announced SoC.

The DRIVE PX2 is designed for self-driving cars and with having so much information to process, the SoC powering this has to be a beast. NVIDIA hasn't formally announced the SoC successor to the Tegra X1, but there's speculation that this System-on-a-Chip could be a refined version of the delayed "Parker" SoC.

  • How AMD's Proprietary Linux Driver Evolved In 2015

    Last month I showed how AMD's open-source driver performance evolved in 2015 while today's article is looking at how the closed-source AMD / Radeon Technologies Group proprietary driver has evolved over the course of the year.

  • X.Org Server Development Slows To Lowest Point In A Decade

    In 2015 there were just 436 commits for the entire year -- in 2014 there were 923 commits, which was about average recently. The high point of X.Org Server's development was around 2008 when there were 2,114 commits in a single year. Except for 2015, every year saw close to a thousand or more commits going back a decade. In 2004 there were 590 commits while in 2003 there were 125 commits. Of course, prior to 2004 the X.Org Server was technically the XFree86 code-base.

  • PCI Express Speed Changes Still Being Worked On For Nouveau

    Karol Herbst today published the fourth version of the PCI Express speed changes. These nine patches add support for parsing the capable PCI speed from the video BIOS for "tesla" GPUs and newer, wires up support for changing the PCI Express speed for Tesla/Fermi/Kepler (and newer), and then lastly hooks up support for changing the PCI-E speed based upon the performance state (pstate) level.

  • Mesa Saw The Most Commits Last Year Since 2010
  • Better Multi Indirect Draw Support Coming To Mesa

    Ilia Mirkin has seemingly not taken much time off from his Mesa hacking for the holidays. On Thursday this developer who most frequently works on the Nouveau and Freedreno drivers has published patches for better ARB_multi_draw_indirect handling.

    The GL_ARB_multi_draw_indirect extension is mandated by OpenGL 4.3. Core Mesa and all of the key drivers have already handled this extension with the exception of Nouveau NV50. However, Mirkin is hoping to enhance the implementation.

DragonFlyBSD Rebases Its Intel Kernel Graphics Driver Against Linux 4.0

Filed under
Graphics/Benchmarks
BSD

DragonFlyBSD's Francois Tigeot has done some more great work in allowing their open-source Intel graphics driver to be more featureful and comparable to the Linux i915 kernel DRM driver for which it is based.

While DragonFly's i915 DRM driver started out as woefully outdated compared to the upstream Linux kernel code, the work done by Tigeot and others is quite close to re-basing against the latest mainline code. With patches published recently, the DragonFlyBSD driver would now be comparable to what's in the Linux 4.0 kernel.

  • Will Linux 4.5 Bring Any Performance Boost For Pre-AMDGPU Radeon?

    While I've been writing a lot the past few days about the AMDGPU kernel driver given it's landing PowerPlay support for Linux 4.5, I took some time today for running some Radeon (non-AMDGPU) DRM tests to see if the performance of this DRM-next code has changed compared to Linux 4.4 near-final.

  • How AMD's Open-Source GPU Driver Performance Evolved In 2015: Big Wins

    The graphics cards used in this comparison were limited to those supported by the Radeon DRM driver at the end of 2014. Back then, the AMDGPU driver was not public so cards like the R9 285 Tonga were unsupported. Even back then, the Radeon R9 290 on Ubuntu 14.10 was just running LLVMpipe. So for this comparison I tested just the Radeon R7 370, Radeon HD 6870, and Radeon HD 6950 for both R600g and RadeonSI Gallium3D coverage.

  • Christmas Miracle: Intel Mesa Driver Tessellation For Ivy Bridge & Haswell

Anonymous reviews in GNOME Software

Choosing an application to install is hard when there are lots of possible projects matching a specific search term. We already list applications based on the integration level and with useful metrics like “is it translated in my language” and this makes sure that high quality applications are listed near the top of the results. For more information about an application we often want a more balanced view than the PR speak or unfounded claims of the upstream project. This is where user-contributed reviews come in. Read more

Getting Started with ZFS on Debian 8

I am quite careful about protecting my files, which include images, videos, and various documents – mostly drafts of my science fiction novels – that I have been working on for years. Images and videos of family, including the birth of my son, his first smile, and other moments are way too valuable for me to lose. But, all sorts of things can lead to data corruption, and I would not be happy if that happened to any of my valuable files. That’s where filesystems like ZFS and Btrfs enter the picture. Read more
