NVIDIA vs. AMD 2D Linux Drivers: Catalyst Is Getting Quite Good At 2D

Filed under
Graphics/Benchmarks

Our latest Linux graphics driver benchmarks are taking a look at the binary NVIDIA and AMD Catalyst drivers using the latest versions while running on Ubuntu 14.04 LTS. It's been a while since last time we closely compared the two proprietary GPU drivers with 2D workloads on an array of graphics cards so these results should be definitely interesting.

NVIDIA Linux 2D Benchmarks With The GeForce GTX 980

Filed under
Graphics/Benchmarks

Last week having done the GeForce GTX 980 Linux review with a ton of OpenGL benchmarks followed by GTX 980 OpenCL benchmarks and yesterday even running some updated NVIDIA VDPAU Linux benchmarks, next up for this high-end Maxwell graphics processor are some 2D performance benchmarks using NVIDIA's binary blob.

This weekend I ran some fairly straight forward NVIDIA 2D benchmarks from their 343.22 proprietary driver: workloads included QGears2, Render Bench, and GtkPerf -- all ran of course by the automated Phoronix Test Suite benchmarking software.

Freedreno Gallium3D Is Passing 90%+ Of Piglit Tests

Linux

In addition to doing the xf86-video-freedreno 1.3.0 release this weekend, Rob Clark also took the opportunity to write a lengthy blog post on the progress made for the open-source, reverse-engineered Linux graphics driver stack for Qualcomm's Adreno graphics hardware. The few contributors involved have done a stunning job over the past few months to implement much of OpenGL 3 for this ARM graphics driver and make other improvements -- all without the support or backing of Qualcomm.

Freedreno 1.3.0 DDX Brings Several Fixes

Filed under
Graphics/Benchmarks

Rob Clark has released an updated X.Org DDX driver for his Freedreno driver project that continues to strive towards reverse-engineering the Adreno graphics processors found on Qualcomm's ARM SoCs.

As with most X.Org DDX updates in general, the xf86-video-freedreno 1.3 release isn't too incredibly interesting with most Linux graphics driver innovations happening within the DRM/KMS and Mesa/Gallium3D areas. However, for users of the open-source Freedreno driver there are some notable fixes.

Linux

For those that have been mailing in requests for benchmarks of Mesa 10.3 with Linux 3.16~3.17 given that's what most Q4'2014 Linux distributions are setting to ship, here's a 15-way graphics processor comparison on this stack.

Fedora 21 vs. Ubuntu 14.10 Development Benchmarks

Filed under
Graphics/Benchmarks

With the very latest development packages for Ubuntu 14.10 and Fedora 21, here's some new Linux benchmark results when running from the Core i7 5960X platform and using the new MSI X99S SLI PLUS.

The MSI X99S SLI PLUS motherboard played well with both Ubuntu 14.10 and Fedora 21 that are powered by the modern Linux 3.16 kernel. As a quick comparison just for kicks I ran some benchmarks using all of the same hardware and the stock settings for each of F21 and Ubuntu Utopic on this system with the latest packages as of yesterday~today.

15-Way GPU Comparison With Mesa 10.3 + Linux 3.17

Filed under
Graphics/Benchmarks

For those that have been mailing in requests for benchmarks of Mesa 10.3 with Linux 3.16~3.17 given that's what most Q4'2014 Linux distributions are setting to ship, here's a 15-way graphics processor comparison on this stack.

Using the Mesa 10.3 packages that recently landed in Ubuntu 14.10 Utopic Unicorn are some fresh benchmarks of the latest Ubuntu 14.10 state but with switching to the mainline Linux 3.17 kernel. All tests were done from the Intel Core i7 4770K system with Gigabyte Z97-HD3 motherboard, 8GB of RAM, and 140GB Western Digital WD1500HLHX HDD. Ubuntu 14.10 was in its updated state as of a few days ago with Unity 7.3.1, X.Org Server 1.16.0, xf86-video-ati 7.4.0, xf86-video-intel 2.99.914, and xf86-video-nouveau 1.0.11. Mesa 10.3.0 was present while as said we upgraded to the Linux 3.17 Git kernel as Ubuntu 14.10 by default is shipping with Linux 3.16; there's a few DRM driver improvements in 3.17 worth testing.

NVIDIA To Issue An Update On Their Support Of Mir & Wayland

Filed under
Graphics/Benchmarks

While there's no supportive driver out at this time, NVIDIA continues to be working in the direction of supporting non-X11 windowing systems like Mir and Wayland.

XDC2014 Bordeaux should be very interesting next week. Besides AMD providing an update on moving towards a unified open-source driver and NVIDIA still working on the new Linux OpenGL ABI, Andy Ritger of NVIDIA has a secondary talk regarding Enabling Alternative Window Systems with a non-Mesa Graphics Driver Implementation.

NVIDIA Suggests Explicit Synchronization For Nouveau

Filed under
Graphics/Benchmarks

As another interesting NVIDIA Linux news item before ending out the month are some patches published just before the start of the weekend by NVIDIA. A NVIDIA developer has proposed explicit synchronization support for the Nouveau driver, complete with some "RFC" patches.

Lauri Peltonen, a NVIDIA System Software Engineer that's part of the Tegra software team, posted the set of seven open-source patches on Friday. The open-source DRM drivers already support implicit synchronization whereby fences are attached to buffers and the kernel manages the fences automatically based on buffer reads/writes. The explicit synchronization feature being pursued by the Tegra team is where fences are passed independently and the kernel takes and emits fences to/from user-space when submitting work, as explained by Lauri on the mailing list.

AMD Is Working On A New VA-API State Tracker For Gallium3D

Filed under
Graphics/Benchmarks

Years ago there was a VA-API state tracker within Gallium3D for offering drivers support for the Video Acceleration API. That implementation, however, was dropped back in 2012 as it was largely unmaintained and the VDPAU state tracker proved to be more popular. Now, however, it seems AMD is working to introduce a new VA-API implementation for Gallium3D.

Published on Friday by AMD's Leo Liu was a set of video-related patches for Gallium3D that included a new VA-API state tracker written by Christian König. This new state tracker isn't just a re-send of the earlier patch series: there is new code included but the copyrights also indicate some of the code is from its earlier 2010 state by the community.

CPod – A Simple, Beautiful And Cross-platform Podcast App

Podcasts have become very popular in the last few years. Podcasts are what’s called “infotainment”, they are generally light-hearted, but they generally give you valuable information. Podcasts have blown up in the last few years, and if you like something, chances are there is a podcast about it. There are a lot of podcast players out there for the Linux desktop, but if you want something that is visually beautiful, has slick animations, and works on every platform, there aren’t a lot of alternatives to CPod. CPod (formerly known as Cumulonimbus) is an open source and slickest podcast app that works on Linux, MacOS and Windows. CPod runs on something called Electron – a tool that allows developers to build cross-platform (E.g Windows, MacOs and Linux) desktop GUI applications. In this brief guide, we will be discussing – how to install and use CPod podcast app in Linux. Read more

Security: Updates, Anonymity, EFF and Open Source Security Podcast

  • Security updates for Monday
  • For Hackers, Anonymity Was Once Critical. That’s Changing.

    “This is a profession for a lot of people now,” she added. “And you can’t fill out a W-9 with your hacker handle.”

    [...]

    “The thing I worry about today,” he added, taking a more serious tone, “is that people don’t get do-overs.” Young people now have to contend with the real-name policy on Facebook, he said, along with the ever-hovering threats of facial-recognition software and aggregated data. “How are you going to learn to navigate in this world if you never get to make a mistake — and if every mistake you do make follows you forever?”

  • EFF Leader: Security Decisions Are Different When Women Are In The Room
    Women will have their technical credentials doubted throughout their career, said the Electronic Frontier Foundation's Eva Galperin, but being able to participate in important privacy and security decisions makes it worthwhile.
  • Open Source Security Podcast: Episode 115 - Discussion with Brian Hajost from SteelCloud
    Josh and Kurt talk to Brian Hajost from SteelCloud about public sector compliance. The world of public sector compliance can be confusing and strange, but it's not that bad when it's explained by someone with experience.
