Leftovers: Graphics

Filed under
Linux

Includes a few repetitions

  • NVIDIA GeForce 700 Series On Linux Run Excellent
  • Intel's HD4600 versus AMD's 4600 on Linux ... with special guests

    Phoronix is continuing to test the performance of open source Linux drivers on Source Engine games with this installation focusing on the performance of the Haswell i7-4770K. They compare it to a number of RV770 based AMD GPUs as well as the newer HD 6450. As you can see in the result the performance of the HD 6450 and HD 4550 are almost exactly the same and are the only two Radeons that do not leave the Intel's GPU in the dust. If you have experience with the HD 4650 you have a very good idea as to how Intel's 4600 performs as the results are very similar.

  • Wayland's Weston Received New Features Yesterday

    There's been work on Weston to support run-time switchable renderers for Weston. That's now been accomplished and with the latest Git code it's easy to switch from Pixman to the OpenGL renderer. The debug binding of "mod-shift-space W" will now cause the compositor to switch from using the software-based Pixman renderer to the OpenGL renderer. This key-bind renderer switching is useful for debugging, stressing the run-time switchable renderer support, and there's cases where the OpenGL renderer isn't used right away by Weston since the Pixman renderer is able to start-up more quickly.

  • Khronos Keeps Advancing, Pushing Its Standards
  • AMD Radeon R9 290 On Linux
  • The State Of Mesa OpenGL GL3/GL4 Updated

    With the forthcoming release of Mesa 10.0 there is now OpenGL 3.2 and OpenGL 3.3 compliance. That compliance is for core Mesa and the Intel DRI driver. The Radeon and Nouveau drivers don't have as advanced OpenGL support since most of the upstream GL / GLSL enablement is done by Intel developers and thus the focus on their own driver while the Radeon/Nouveau support usually trails.

  • Libdrm 2.4.48 Has New Hardware Support

    Libdrm, the DRM library that interfaces between the user-space graphics components (namely Mesa and the X.Org drivers) with the Linux kernel DRM drivers, is now up to version 2.4.48. Big with libdrm 2.4.48 is Intel "Broadwell" and AMD Radeon "Hawaii" GPU support.

Reglue Seeks ’12 Geeks of Christmas’

Filed under
Linux

When I read on Monday that my friend Ken Starks had come-up with the 12 Geeks of Christmas idea for his Reglue project, my first thought was “what a wonderful idea.”

In case you don’t know, Reglue is a nonprofit run by Starks down in Texas that refurbishes old computers, loads them up with GNU/Linux and the necessary software, then gives them to school age children who’s parents can’t afford a decent computer.

When you think about it, this not only gives kids who can’t afford it a much needed computer for their school work, it also gives them the added advantage of learning to use an operating system other than Windows or OS X while being opened-up to the possibilities of free and open source software. I can’t help but wonder how many of tomorrow’s FOSS developers are being nurtured by Starks and his Reglue project just by dint of learning their way around Linux.

Close on the heels of the revelation that Samsung’s NX300M camera runs Tizen, this week saw an announcement by Nexcom of a developer-focused, Intel Atom-based automotive computer called the VTC 1010-IVI that supports the Tizen In-Vehicle Infotainment (IVI) stack, plus news of a Tizen-enabled Samsung smart refrigerator. Meanwhile, Samsung’s first Tizen phones are rumored to be under test at Korean mobile carriers.

Green500 List top 10 are all powered by NVIDIA Tesla GPUs and Linux

Filed under
Linux

The November 2013 edition of the Green500 List has be released, just two days after the TOP500 List.

Unlike the TOP500 List, which lists 500 of the worlds fastest supercomputers, the Green500 List lists the most energy-efficient supercomputers that made the TOP500 List. So for the Green500, it’s not about how fast, but how energy-efficient. That’s why China’s Tianhe-2, which topped the November 2013 TOP500 List, did not even make the top 10 of the Green500 List for the same month. Rather, it ranked number 41.

Long-term Embedded Linux Maintenance andd New Device From CompuLab

  • Long-term Embedded Linux Maintenance Made Easier
    The good old days when security breaches only happened to Windows folk are fading fast. Malware hackers and denial of service specialists are increasingly targeting out of date embedded Linux devices, and fixing Linux security vulnerabilities was the topic of several presentations at the Embedded Linux Conference Europe (ELCE) in October. One of the best attended was “Long-Term Maintenance, or How to (Mis-)Manage Embedded Systems for 10+ Years” by Pengutronix kernel hacker Jan Lübbe. After summarizing the growing security threats in embedded Linux, Lübbe laid out a plan to keep long-life devices secure and fully functional. “We need to move to newer, more stable kernels and do continuous maintenance to fix critical vulnerabilities,” said Lübbe. “We need to do the upstreaming and automate processes, and put in place a sustainable workflow. We don’t have any more excuses for leaving systems in the field with outdated software.”
  • CompuLab Has Upgraded Their Small Form Factor "IPC" Line To Kabylake
    HARDWARE -- Our friends and Linux-friendly PC vendor, CompuLab, have announced a new "IPC" line-up of their small form factor computers now with Intel Kabylake processors. In the past on Phoronix we tested CompuLab's Intense-PC (IPC) and then the IPC2 with Haswell processors, among other innovative PCs from CompuLab. Now they are rolling out the IPC3 with Intel's latest Kabylake processors.
  • Fanless mini-PC runs Linux Mint on Kaby Lake
    Compulab launched a rugged “IPC3” mini-PC that runs Linux on dual-core, 7th Gen Core i7/i5 CPUs, and also debuted three GbE-equipped FACE expansion modules. Compulab has opened pre-orders starting at $693 for the first mini-PCs we’ve seen to offer the latest, 14nm-fabricated 7th Generation Intel Core “Kaby Lake” processors. The passively cooled, 190 x 160 x 40mm IPC3 (Intense PC 3), which is available in up to industrial temperature ranges, follows two generations of similarly sized IPC2 mini-PCs. There’s the still available, 4th Gen “Haswell” based IPC2 from 2014 and the apparently discontinued 5th Gen “Broadwell” equipped IPC2 from 2015.
  • Compulab IPC3 is a tiny, fanless PC with Intel Kaby Lake CPU
    Compulab is an Israeli company that makes small, fanless computers for home or commercial use. The company’s latest mini PC aimed at enterprise/industrial usage is called the IPC3, and it has a die-cast aluminum case with built-in heat sinks for passive cooling and measures about 7.4″ x 6.3″ x 1.6″.

Games for GNU/Linux

  • Imperium Galactica II: Alliances released for Linux & SteamOS, seems native too
    Imperium Galactica II: Alliances [GOG, Steam] just released for Linux & SteamOS and it looks like it's a native version. Note: My friends at GOG sent over a copy, so big thanks to them. There's no sign of DOSBox or Wine and I had no idea this game had ever been ported to Linux. Pretty awesome really for a game like this to get a proper Linux build when it gets a new release.
  • Nearly five years after the Kickstarter, Carmageddon still isn’t on Linux despite the stretch goal being reached
    The problem here, for me, is that they later did a revamp of the title called Carmageddon: Max Damage. This was to fix some problems, boost sales again and port it to consoles. Carmageddon: Max Damage also never made it to Linux. Fun fact, they actually released a trailer where they just run over a ton of penguins, make from that what you will: Not saying this was trolling the entire Linux gaming community, but it sure felt like it after their previous trolling attempts directed at our official Twitter account.
  • Valve Rolls Out New Steam Client Stable Update with Promised Linux Changes, More
    Today Valve announced the availability of a new stable update of the Steam Client for all supported platforms, including the company's SteamOS operating system for Steam Machines, as well as GNU/Linux, macOS, and Microsoft Windows. Bringing all the new features during the Beta stages of development, the new Steam Client update improves the interaction between the Steam runtime and your GNU/Linux distribution's libraries. This is a huge and long-anticipated milestone for the Steam Client, which, unfortunately, did not work out-of-the-box on all Linux-based operating systems.
