  • The Best Graphics Card Brands For NVIDIA/AMD GPUs As A Linux Consumer?

    One of the most frequent topics I'm emailed about is any brand recommendations among NVIDIA and AMD AIB partners for graphics cards. For Linux users, is there a particular brand preference for graphics cards?

    The short story is, no, there isn't one particular brand when selecting either a GeForce or Radeon graphics card that a Linux gamer/enthusiast should go with over another AIB partner. Over the past 12 years of running Phoronix, there has been no single AIB partner that superbly stands out compared to the rest when it comes to graphics card AIB partner brands like ASUS, Zotac, HIS, MSI, etc. They all work under Linux, rarely the AIB differences extend beyond the heatsink/cooler and any default clock speed differences, and I haven't seen one that's over-the-top crazy about Linux. I also haven't seen any major partner consistently put the Tux logo or other Linux markings on their product packaging, let alone incorporate any Linux drivers onto their CD/DVD driver media.

  • VLC Now Has Zero-Copy Support For GStreamer Video Decoding

    It was just last week we got to write about VLC 3.0 features and early planning for VLC 4.0 while this weekend in Git there is another feature to add to the list.

    The latest VLC development code now supports zero-copy GStreamer video decoding. With the zero-copy comes increased efficiency and performance.

  • NVIDIA GeForce GT 710: Trying NVIDIA's Newest Sub-$50 GPU On Linux

    The GeForce GT 710 is a cut-down version of the Kepler GK208, the already low-end core used by the lines of the GT 720 and GT 730 graphics cards as well as the mobile GT 720M/730M/735M/740M graphics processors. This really isn't a graphics card for gamers or anyone needing any serious GPU performance but rather as an upgrade for an entry-level system, someone just wanting to upgrade from their integrated graphics, and other minimally-demanding use-cases.

  • Mesa 11.2 Is Set For Branching In Just Two Weeks, Release In Just Over One Month

    The race is on to see if any of the Mesa/Gallium3D hardware drivers (or core Mesa itself) will reach any new version levels for Mesa 11.2.

  • AMD Is Looking At A Interoperability Interface For OpenCL Outside Of Mesa

    AMD's Marek Olšák has begun exploring an interoperability interface for OpenGL within Mesa and having a non-Mesa OpenCL implementation (not Clover OpenCL Gallium3D).

    Likely as part of their HSA work and hopefully in providing better AMD open-source OpenCL support aside from the (currently limited) Gallium3D Clover state tracker, Marek is trying to hash out an interface for allowing interoperability with "MesaGL" and a non-Mesa OpenCL driver.

Ubuntu

As I'm in the process of retiring an old AMD Opteron dual-socket system, prior to decommissioning it, I figured it would be fun to go back and re-benchmark all of the Ubuntu LTS releases going all the way back to the legendary 6.06 Dapper Drake release. So here are some fresh benchmarks of this AMD Shanghai system with eight cores and 16GB of RAM when re-benchmarking the releases from Ubuntu 6.06 through the latest Ubuntu 16.04 LTS development state.

Linux Benchmarks Of The C.H.I.P. $9 Computer

Linux

While Next Thing Co is still working to fulfill orders on the C.H.I.P. $9 computer over the next several months, I noticed that some benchmarks of this cheap Raspberry Pi competitor have begun appearing on OpenBenchmarking.org via the Phoronix Test Suite. Here are some of those benchmark results for this ARB single-board computer.

For those that don't recall this crowd-funding campaign, the C.H.I.P. is a $9 computer with a 1GHz ARM single-core processor, 512MB of RAM, and 4GB of storage. The C.H.I.P. is cheap. I hadn't paid much attention to the campaign since I'm more into high-performance ARM chips than whatever the cheapest ARM SBC is around. However, these early benchmark results on OpenBenchmarking.org are rather interesting.

  • Intel Is Now Bringing The Observation Architecture To Their Linux Driver

    While Haswell processors have been available for a few years now, finally work is materializing on supporting the hardware's Observation Architecture.

    The Observation Architecture is a set of performance counters for Haswell and newer. Developers interested in all the technical details on these new performance counters can see this public documentation.

  • RadeonSI/R600g Mesa 11.2-devel Clover OpenCL Benchmarks On Linux 4.5

    Following this morning's article about Russian Super-Computing Users Get Tired Of Catalyst, Start Looking At Open-Source AMD, I decided to run some fresh Radeon open-source OpenCL benchmarks on my own using the Gallium3D Clover state tracker with the HPC researchers also being curious how this very latest open-source AMD graphics stack is performing. Here are some initial results with Mesa 11.2-devel Git built against LLVM 3.9 SVN (thanks Padoka!) and using the Linux 4.5 Git kernel.

  • leaking buffers in wayland

    So in my last blog post I mentioned Matthias was getting SIGBUS when using wayland for a while. You may remember that I guessed the problem was that his /tmp was filling up, and so I produced a patch to stop using /tmp and use memfd_create instead. This resolved the SIGBUS problem for him, but there was something gnawing at me: why was his /tmp filling up? I know gnome-terminal stores its unlimited scrollback buffer in an unlinked file in /tmp so that was one theory. I also have seen, in some cases firefox downloading files to /tmp. Neither explanation sat well with me. scrollback buffers don’t get that large very quickly and Matthias was seeing the problem several times a day. I also doubted he was downloading large files in firefox several times a day. Nonetheless, I shrugged, and moved on to other things…

  • Open Source and .NET — Why It's Not Picking Up
    Open-source in .NET is not picking up. Despite good efforts from many good people and companies, it seems as if the Microsoft developers scene is far from embracing open-source. Why is this happening, and is there still hope for change? [...] But, this doesn't seem to be enough. OSS projects in .NET are not striving; there is not much innovation happening in this space; and OSS communities aren't being formed. It is all left as a dream we keep dreaming, but never actually getting to fulfil.
  • LLVM Clang 3.8 Compiler Optimization Benchmarks With -Ofast
    A few days ago I posted a number of LLVM Clang optimization level benchmarks using the latest code for the upcoming Clang 3.8 release. Those tests went from -O0 to -O3 -march=native, but many Phoronix readers wanted -Ofast so here are those results too. I didn't include -Ofast in the original tests since I don't know of many using this optimization level within a production capacity considering it has the potential of doing unsafe math as it disregards standards compliance in the name of performance. However, since several readers requested it and I still had this LLVM/Clang 3.8 build around in the same system configuration, I added in extra runs with -Ofast and -Ofast -march=native.
