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.

  • Features To Start Looking Forward To For Linux 4.5

    With Linux 4.4 expected next weekend, here's a look at some of the early features we've already been talking about on Phoronix that should be on the table for the Linux 4.5 merge window.

  • 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.

  • The Open-Source NVIDIA Linux Driver Continued Evolving In 2015

    This year the open-source NVIDIA Linux driver (Nouveau) continued to evolve with improvements for re-clocking, the start of OpenGL 4 support, and other new functionality. Here's a recap along with some performance benchmarks showing how the OpenGL performance evolved over the past 12 months.

  • AMD/Radeon Has Continued Making Much Linux Graphics Progress

    AMD's open-source graphics driver stack continued maturing in 2015 while Catalyst (now known as Radeon Software) releases were rare. AMD's open-source driver stack now supports OpenGL 4.1 for GCN GPUs and select pre-GCN graphics cards plus the other driver stack also matured in other ways this year.

  • NIR Mesa Functions Support Is Coming Along With SPIR-V To NIR

    Mesa developer Jason Ekstrand has published a patch set today for providing real function support inside NIR, the new Mesa intermediate representation.

    Up to now they haven't had suitable support for functions sans the single-function main(). However, these 12 patches wire everything up for functions.

  • How Haswell OpenGL Performance On Linux Changed In 2015

    Yesterday I published our usual end-of-year results showing how AMD's open-source driver evolved in 2015 with regard to its OpenGL performance. For your viewing pleasure today are similar results but on the Intel Haswell side looking at how the open-source Intel Linux driver performance changed since the end of 2014.

  • 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

  • Now You Can Use uTorrent Without Ads, Thanks To New Subscription Model
    In the past, the parent company Bittorrent Inc. has relied on an ad-based revenue model to keep uTorrent up and running, but now they have realized the need for a premium experience for the users by charging a nominal amount. Until now, bundled software that hides inside the uTorrent installation package has only consumed space on your computer. The development team is well aware of this issue and that’s why they have come up with the ad-free uTorrent.

Kernel Space: Linux, Graphics

  • Linux kernel bug delivers corrupt TCP/IP data to Mesos, Kubernetes, Docker containers
    The Linux Kernel has a bug that causes containers that use veth devices for network routing (such as Docker on IPv6, Kubernetes, Google Container Engine, and Mesos) to not check TCP checksums. This results in applications incorrectly receiving corrupt data in a number of situations, such as with bad networking hardware. The bug dates back at least three years and is present in kernels as far back as we’ve tested. Our patch has been reviewed and accepted into the kernel, and is currently being backported to -stable releases back to 3.14 in different distributions (such as Suse, and Canonical). If you use containers in your setup, I recommend you apply this patch or deploy a kernel with this patch when it becomes available. Note: Docker’s default NAT networking is not affected and, in practice, Google Container Engine is likely protected from hardware errors by its virtualized network.
  • Performance problems
    Just over a year ago I implemented an optimization to the SPI core code in Linux that avoids some needless context switches to a worker thread in the main data path that most clients use. This was really nice, it was simple to do but saved a bunch of work for most drivers using SPI and made things noticeably faster. The code got merged in v4.0 and that was that, I kept on kicking a few more ideas for optimizations in this area around but that was that until the past month.
  • Compute Shader Code Begins Landing For Gallium3D
    Samuel Pitoiset began pushing his Gallium3D Mesa state tracker changes this morning for supporting compute shaders via the GL_ARB_compute_shader extension. Before getting too excited, the hardware drivers haven't yet implemented the support. It was back in December that core Mesa received its treatment for compute shader support and came with Intel's i965 driver implementing CS.
  • Libav Finally Lands VDPAU Support For Accelerated HEVC Decoding
    While FFmpeg has offered hardware-accelerated HEVC decoding using NVIDIA's VDPAU API since last summer, this support for the FFmpeg-forked libav landed just today. In June was when FFmpeg added support to its libavcodec for handling HEVC/H.265 video decoding via NVIDIA's Video Decode and Presentation API for Unix interface. Around that same time, developer Philip Langdale who had done the FFmpeg patch, also submitted the patch for Libav for decoding HEVC content through VDPAU where supported.

Unixstickers, Linux goes to Washington, Why Linux?

  • Unixstickers sent me a package!
    There's an old, popular saying, beware geeks bearing gifts. But in this case, I was pleased to see an email in my inbox, from unixstickers.com, asking me if I was interested in reviewing their products. I said ye, and a quick few days later, there was a surprise courier-delivered envelope waiting for me in the post. Coincidentally - or not - the whole thing happened close enough to the 2015 end-of-the-year holidays to classify as poetic justice. On a slightly more serious note, Unixstickers is a company shipping T-shirts, hoodies, mugs, posters, pins, and stickers to UNIX and Linux aficionados worldwide. Having been identified one and acquired on the company's PR radar, I am now doing a first-of-a-kind Dedoimedo non-technical technical review of merchandise related to our favorite software. So not sure how it's gonna work out, but let's see.
  • Linux goes to Washington: How the White House/Linux Foundation collaboration will work
    No doubt by now you've heard about the Obama Administration's newly announced Cybersecurity National Action Plan (CNAP). You can read more about it on CIO.com here and here. But what you may not know is that the White House is actively working with the Linux and open source community for CNAP. In a blog post Jim Zemlin, the executive director of the Linux Foundation said, “In the proposal, the White House announced collaboration with The Linux Foundation’s Core Infrastructure Initiative (CII) to better secure Internet 'utilities' such as open-source software, protocols and standards.”
  • Why Linux?
    Linux may inspire you to think of coders hunched over their desks (that are littered with Mountain Dew cans) while looking at lines of codes, faintly lit by the yellow glow of old CRT monitors. Maybe Linux sounds like some kind of a wild cat and you have never heard the term before. Maybe you have use it every day. It is an operating system loved by a few and misrepresented to many.
