Atomic Mode-Setting/Display Support Progresses In Linux 3.20

Filed under
Linux

Going along with many DRM graphics driver improvements for Linux 3.20 is the seemingly never-ending work on atomic mode-setting.

Atomic mode-setting/display support has been talked about for years but is finally nearing a reality within the mainline Linux kernel with drivers like the Tegra DRM driver adding initial support.

With Linux 3.20 there's the actual Linux DRM Atomic IOCTL and along with other changes means that Linux user-space can start accessing the atomic support, albeit it's hidden for now behind the experimental drm-atomic=1 flag.

Industrial box-PC takes Linux-on-Haswell to extremes

Filed under
Linux

The Acnodes “FES8670″ is a rugged industrial box-PC that runs Linux on a 4th Gen Core CPU, and offers four GbE ports and numerous storage and display ports.

So far, we’ve still only seen one company (Congatec) announce products based on Intel’s new 5th Generation Core (“Broadwell”) processors, although we expect many more to break cover at Embedded World next month. Yet, there’s still plenty of juice left in the 4th Gen Haswell Core chips, which drive Acnodes’s powerhouse FES8670. Earlier Acnodes industrial PCs have included the Atom D2550-based FES2215.

Embedded Development with ARM mbed on Linux

Filed under
Linux

The ARM CPU used in the BeagleBone Black and other single board computers is designed to interface with half to a few gigabytes of RAM and allow a full operating system such as Linux to be run on the computer. (See my long series of reviews on Linux.com of ARM-based computers that run Linux). By contrast the ARM Cortex-M is a microcontroller level chip which might run at 16-100Mhz, contain 2-100kb of RAM, and some flash memory to contain only the program that you want to execute.

IoT, Revolution In Personal Computing, or FLOSS Taking Over the World of IT

Filed under
GNU
Linux

What can you say? In a few short years, that other OS has gone from mainstream to niche and Android/Linux and GNU/Linux are stepping up to displace it as the goto OS of the world. It’s all good. This is the right way to do IT with the world making its own software throughout the whole stack: OS on client and server and a ton of applications too. There is no need for a monopoly in IT. The world wants a revolution not lock-in.

Just Switch to Linux if You Want to Download Lots of Freeware

Filed under
Linux

We’ve been banging on about the horrific and broken Windows software ecosystem for a long time now. Rather than installing applications from Download.com and every other freeware site, you should just switch to Linux if you want to download freeware safely.

Yes, we’ve tried to recommend some tips, but the only really good one we can come up with is “just use Ninite.” “Just switch to Linux if you want to download freeware” is another good one.

NVIDIA's Latest Maxwell Line-Up Against AMD With Catalyst On Linux

Graphics/Benchmarks
Linux

Last week NVIDIA released the GeForce GTX 960, a great $200 GPU for Linux gamers that is based on their new power-efficient Maxwell architecture. On launch-day I delivered some initial performance figures of the full GeForce GTX 900 series line-up along with other graphics cards and following that I did many new NVIDIA Linux GPU tests going back to the GeForce GTX 400 (Fermi) series. Not part of those tests were any AMD Radeon graphics cards while in this article are such numbers in making a new 18-way graphics card comparison with the latest Linux graphics drivers.

Linux Desktop Evolution: Minor, Invisible, or Aesthetic

Filed under
GNU
Linux

In the last two years, the Linux desktop has settled into a period of quiet diversity. The user revolts of 2008-2012 are safely in the past, and users are scattered among at least seven major desktops -- Cinnamon, GNOME, KDE,LXDE, MATE, Unity, and Xfce -- and likely to stay that way.

So what comes next? What will the next innovations on the desktop be? Where will they come from? Prediction is as safe as investing in penny mining stocks, but some major trends for the next couple of years seem obvious without the bother of a tarot reading.

Graphics: Mesa 17.2.6 RC, AMDGPU, and Vulkan

  • Mesa 17.2.6 release candidate
  • Mesa 17.2.6 RC Arrives With 50+ Fixes
    While Mesa 17.3 is imminent and should be released as stable within the next few days, Mesa 17.2.6 is being prepped for release as the current point release.
  • 43 More AMDGPU DC Patches Hit The Streets
    While the massive AMDGPU DC infrastructure has been merged for Linux 4.15, the flow of improvements to this display code continues and it looks like the next few kernel cycles at least could be quite busy on the AMD front.
  • A Prototype Of The Vulkan Portability Initiative: Low-Level 3D To Vulkan / D3D12 / Metal
    A Mozilla engineer has put out a prototype library in working on the Vulkan Portability Initiative for allowing low-level 3D graphics support that's backed by Vulkan / Direct3D 12 / Metal. With Apple sticking to their own Metal graphics API and Direct3D 12 still being the dominant graphics API on Windows 10, The Khronos Group has been working towards better 3D portability for where Vulkan may not be directly supported by the OS/drivers or otherwise available. They've been working to target a subset of the Vulkan API that can be efficiently mapped to these other native graphics APIs and to have the libraries and tooling for better compatibility and code re-use of these different graphics APIs.

Kernel: Linux 4.15, TLDR, and Linus Torvalds' Latest Rant

  • Linux 4.15 Adds AMD Raven Ridge Audio ID
    Not only is AMD Stoney Ridge audio (finally) being supported by the Linux 4.15 kernel, but it also looks like Raven Ridge audio should now be working too.
  • Linux 4.14.2 Fixes The BCache Corruption Bug
    Normally I don't bother mentioning new Linux kernel point releases on Phoronix unless there are some significant changes, as is the case today with Linux 4.14.2.
  • TLDR is what Linux man pages always should have been
    If you get stuck using a Linux tool, the first port of call shouldn’t be to Stack Overflow, but rather its “man pages.” Man — which is short for manual — retrieves documentation for a given program. Unfortunately, this can often be dense, hard to understand, and lacking in practical examples to help you solve your problem. TLDR is another way of looking at documentation. Rather than being a comprehensive guide to a given tool, it instead focuses on offering practical example-driven instructions of how something works.
  • Linux creator Linus Torvalds: This is what drives me nuts about IT security
    Developers are often accused of not thinking about security, but Linux kernel founder Linus Torvalds has had enough of security people who don't think about developers and end-users. After blasting some kernel developers last week for killing processes in the name of hardening the kernel, Torvalds has offered a more measured explanation for his frustration with security myopia. While he agrees that having multiple layers of security in the kernel is a good idea, certain ways of implementing it are not, in particular if it annoys users and developers by killing processes that break users' machines and wreck core kernel code. Because ultimately, if there are no users, there's not much point in having a supremely secure kernel, Torvalds contends.

Unity 7 Hoping To Become An Official Flavor For Ubuntu 18.04 LTS

While Canonical abandoned their work on the Unity desktop environment in favor of the Unity-inspired customized GNOME Shell that debuted in Ubuntu 17.10, some within the community have remained interested in maintaining Unity 7 and even getting it into an official spin/flavor of Ubuntu. Posted today to the community.ubuntu.com was a Unity maintenance roadmap, reiterating the hope by some in the Ubuntu community for Ubuntu Unity to become an official LTS distribution of Ubuntu. They are hoping to make it an official flavor alongside Kubuntu, Ubuntu Budgie, Xubuntu, and others. Read more Original/direct: Unity Maintenance Roadmap

Programming/Development: Django and Google India

  • An introduction to the Django ORM
    One of the most powerful features of Django is its Object-Relational Mapper (ORM), which enables you to interact with your database, like you would with SQL. In fact, Django's ORM is just a pythonical way to create SQL to query and manipulate your database and get results in a pythonic fashion. Well, I say just a way, but it's actually really clever engineering that takes advantage of some of the more complex parts of Python to make developers' lives easier.
