Benchmarking The Low-Cost PINE 64+ ARM Single Board Computer

Filed under
Graphics/Benchmarks

As an alternative to the Raspberry Pi 3 for a low-cost 64-bit ARM (AArch64) development board is the PINE 64, which was successfully Kickstarted as a "$15 64-bit single board super computer" that generated more than 1.7 million dollars. The PINE 64 is still shipping out in limited quantities for now, but the folks behind this project were kind enough to send over a sample of their PINE 64 1GB SBC for some benchmarking.

AMD GPU-PRO vs. NVIDIA Linux OpenCL Compute Performance

Filed under
Graphics/Benchmarks

Following this week's AMD vs. NVIDIA Linux OpenGL and Vulkan benchmarks, you may be wondering about the performance of OpenCL GPGPU performance particularly around AMD's new hybrid Linux driver stack. So for your viewing pleasure today are some OpenCL benchmarks on AMD Radeon and NVIDIA GeForce hardware using the newest drivers.

  • AMD Publishes Polaris Patches To Linux Kernel With Baffin & Ellesmere PCI IDs

    AMD Polaris is built using a 14nm FinFET fabrication process. The fourth generation GCN architecture for new Radeon GPUs brings a new memory controller, new multimedia cores, and a new geometry processor. Moreover, Polaris chips will support both HDMI 2.0a and DisplayPort 1.3, and are equally capable of encoding and decoding H.265 video up to 4K resolution.

  • Red matter and green blood; Vulkan runs on Linux

    Last week AMD released a new GPU-PRO Beta driver stack and this Monday, NVIDIA released the 364.12 beta driver, both of which support Vulkan and meant that Phoronix had a lot of work to do. Up for testing were the GTX 950, 960, 970, 980, and 980 Ti as well as the R9 Fury, 290 and 285. Logically, they used the Talos Principal test, their results compare not only the cards but also the performance delta between OpenGL and Vulkan and finished up with several OpenGL benchmarks to see if there were any performance improvements from the new drivers. The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.

  • GLVND GLX Support Being Worked On For The X.Org Server

    Red Hat's Adam Jackson has taken to working on X.Org Server patches for supporting GLVND within a GLX world (rather than just EGL) via the GLX_EXT_libglvnd extension. GLVND, of course, is NVIDIA's OpenGL Vendor Neutral Dispatch Library.

AMD vs. NVIDIA Vulkan & OpenGL Linux Performance With The New Drivers

Filed under
Graphics/Benchmarks

Thanks to AMD having released their new GPU-PRO "hybrid" Linux driver a few days ago, there is now Vulkan API support for Radeon GPU owners on Linux. This new AMD Linux driver holds much potential and the closed-source bits are now limited to user-space, among other benefits covered in dozens of Phoronix articles over recent months. With having this new driver in hand plus NVIDIA promoting their Vulkan support to the 364 Linux driver series, it's a great time for some benchmarking. Here are OpenGL and Vulkan atop Ubuntu 16.04 Linux for both AMD Radeon and NVIDIA GeForce graphics cards.

  • Linux 4.6 Will Try To Make It Easier To Find Assembly Code Bugs

    Linus Torvalds has honored the request to land the "objtool" stack frame validation support for the Linux 4.6 kernel.

    This new Objtool effort provides build-time object file validation for kernel stack frame correctness. This new objtool user-space utility is run at the kernel's build time to analyze the resulting .o machine code, decode the instruction stream, and checks the interpreted instructions. Suspicious Assembly code patterns are then output with currently this objtool just checking frame pointer usage but other features are planned. Another early limitation is that so far, only x86_64 is supported.

  • Many XFS File-System Changes With Linux 4.6

    Many XFS file-system changes can be found in the upcoming Linux 4.6 kernel release.

    Dave Chinner sent in the XFS updates over night for the Linux 4.6 merge window and it's a heavier pull than normal.

  • NTFS-3G Linux NTFS File-System Driver Updated [Ed: company which helps Microsoft tax Linux]

    Tuxera has published a new stable version of their NTFS read-write driver for Linux.

    This new NTFS-3G Linux driver is marked as 2016.2.22 while the actual release happened just today (not in February as implied by the version number).

  • Nvidia 364.12 released for Linux with official Vulkan, Mir & Wayland support

    Well Nvidia dropped a bit of a big one today didn't they! Nvidia driver version 364.12 is now out and brings in official Vulkan support, Mir support and Wayland support.

  • NVIDIA 364.12 Arrives With Wayland & Mir Support

    NVIDIA's 364 Linux driver series is now available and it's pretty darn exciting!

Nvidia 364.12 Linux Driver Out Now with Vulkan 1.0, Wayland, and Mir Support

  • A Bunch Of New ARM Hardware Will Be Supported With Linux 4.6
  • Making Use Of Intel MPX Extensions On Linux

    Intel MPX memory protection aims to safeguard against buffer overflows in programs assuming you have a supported processor and software stack. Over at Intel's Open-Source Technology Center they published a guide this week on making use of Intel MPX under Linux.

    The software requirements for utilizing Intel Memory Protection Extensions (MPX) on Linux include the Linux 3.10 kernel (but Linux 4.1 or newer is recommended), GCC 5.0 or newer, Glibc 2.20 or newer, Binutils 2.24 or newer, and GDB 7.9 or newer. On the hardware side, MPX support is present with latest-generation Skylake processors and newer. This combination of software and hardware allows for checking pointer references to look for buffer overflows.

  • Intel Skylake Firmware Blobs Get Updated For Graphics & Audio

    New firmware blobs have been updated in linux-firmware Git this morning for Skylake affecting both audio and graphics.

    The new audio firmware is to fix various bugs over the earlier binary-only blob. At least according to Intel, there are no changes besides fixes.

  • WebExtensions in Firefox 48
  • Mozilla's WebExtensions API Is In Good Shape For Firefox 48
    Mozilla has announced that for Firefox 48 their WebExtensions API is considered to be in a stable state. They encourage developers looking to develop browser add-ons to begin using this new API. WebExtensions is an API for implementing new browser add-ons/extensions that makes it easier to port to/from other browsers, is compatible with Firefox's Electroloysis, and should be easier to work with than the current APIs. In particular, Google designed portions of the WebExtensions API around Google's Blink extension API.
  • Mozilla a Step Closer to Thunderbird Decision
    The good news is that the folks at Mozilla seem to be determined to find Thunderbird a good home where it will be able to grow and find newfound success. This isn’t surprising. As Surman pointed out in his post, the project is quite popular among those associated with the foundation — but that popularity is also contributing to the problem Mozilla has with keeping the project in-house.
