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!

  • 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.

AMD Releases Radeon GPU-PRO Beta Driver for Ubuntu Linux with Vulkan Support

NVIDIA GeForce vs. Radeon/AMDGPU OpenGL Performance On Ubuntu 16.04

Filed under
Graphics/Benchmarks

This week we showed how the new AMDGPU driver stack is performing on Ubuntu 16.04 and that the recent generations of Radeon graphics cards are commonly seeing 80~90% the performance of Catalyst. However, it's important to keep in mind that aside from Catalyst being more buggy than the proprietary NVIDIA driver, the NVIDIA binary driver also tends to be more performant. So for putting the Ubuntu 16.04 open-source Radeon numbers into perspective, here are results putting them against the GeForce Kepler and Maxwell graphics cards.

  • Mesa 11.2 Features For When It's Released Very Soon

    Besides Linux 4.5 expected this weekend, the release of Mesa 11.2 is also imminent.

    Mesa 11.2 was originally scheduled for release on 11 March, but obviously that didn't happen with now being a day past then. However, unless an 11.2-rc4 release is warranted, Mesa 11.2.0 should be christened this weekend or early next week.

    For those that weren't keeping up with your Mesa readings on Phoronix over the past three months, there are a lot of improvements, but sadly no OpenGL 4.x breakthroughs to any new levels. The Intel driver is still at OpenGL 3.3 (but soon should be well into a GL4 world once FP64 lands) and the RadeonSI/NVC0/R600 drivers are still at OpenGL 4.1 compliance. The LLVMpipe/Softpipe drivers haven't advanced into an OGL4 world. But a lot of individual extensions for the higher OpenGL 4 levels were implemented for Mesa 11.2 and should make for an interesting next Mesa release three months down the line when we could be seeing OpenGL 4.2~4.3 out of some drivers and thus the bump to Mesa 12.0.

  • There's Still Time To Nominate Someone To The X.Org Board (2016)

    There is still time if you wish to nominate yourself or someone else to run in the elections for this year's X.Org Foundation Board of Directors.

    As already covered previously on Phoronix, everything is gearing up for the 2016 X.Org elections. Besides needing to elect four new members to the Board of Directors, they will be again pursuing their potential merger/acceptance by SPI (Software in the Public Interest), should they get enough votes this time to pursue the by-laws change -- last year it failed due to not enough members voting.

Ask Safia: How do I move from a proprietary software background into open source?

Your inexperience with open source tools definitely is not going to prevent you from participating in the open source community. Regardless of the closed nature of the platforms that you’ve worked with previously, you have all the skills needed to be a valuable open source contributor. If you’ve learned a thing or two about documentation, consider addressing documentation issues on projects. If you had experience in QA or testing, you can start off by user testing the software and identifying areas for improvement or for improving code coverage. Valuing your skill set and the nature of the environments that you have worked in is important. Read more

How Do You Support Your Distro?

I think of them as our own little personal supernovas. There’s a brilliant flash when a Linux distro tosses in the towel and calls it quits. But whenever a distro goes away, it leaves behind the people who’ve used and worked with it on a daily basis. While there’s no formation of a black hole, there is hole at the center of users’ work schedules and that disruption can do serious damage to those relying upon the distro’s stability. And while getting a new distro installed and running isn’t the nightmare it used to be, it’s still a pain. Read more

  • External Plugins in GNOME Software (5)
    There’s a lot of flexibility in the gnome-software plugin structure; a plugin can add custom applications and handle things like search and icon loading in a totally custom way. Most of the time you don’t care about how search is implemented or how icons are going to be loaded, and you can re-use a lot of the existing code in the appstream plugin. To do this you just save an AppStream-format XML file in either /usr/share/app-info/xmls/, /var/cache/app-info/xmls/ or ~/.local/share/app-info/xmls/. GNOME Software will immediately notice any new files, or changes to existing files as it has set up the various inotify watches.

  • Week 1 of May-August Outreachy
    The Outreachy internship requires that interns maintain a blog, writing at least every other week. This shouldn't be a problem for the usability project. For the first few weeks, I'll essentially give a research topic for Diana, Ciarrai and Renata to look into and write about on their blogs. I've structured the topics so that we'll build up to building our usability tests.
