Graphics Driver Changes Coming In The Linux 3.18 Kernel

Filed under
Graphics/Benchmarks
Linux

While the Linux 3.17 kernel isn't being released for a few weeks, we already have a good idea for the DRM graphics driver improvements coming for the Linux 3.18 cycle.

Linux 3.17 has many new features, including many DRM graphics improvements, with Linux 3.18 there's of course more changes to get excited about; it's a never-ending cycle in improving Linux graphics drivers and the kernel stack as a whole. With Linux 3.18 though, it's going to be the first release where the drm-next merge window is closing early. Usually David Airlie, the DRM subsystem maintainer, allows new DRM graphics driver code to be introduced up until the start of the next kernel merge window, with that drm-next code-base then being sent in for mainline inclusion. Beginning with Linux 3.18, Airlie is planning to close the merge window of drm-next around the -rc5 state of the previous release. As a result, this week is likely the last that major new DRM graphics driver code has a chance to land for making the 3.18 window.

CoreOS: Open Source Future of Enterprise Computing?

Filed under
Linux

GNU/Linux is winning pretty much everywhere these days - well, aside from the desktop. On supercomputers, mobiles and embedded devices it dominates completely, but in the world of enterprise computing, where it has certainly done well, there's room for it to take further market share. How might it do that? One of the huge advantages that free software has over traditional closed source programs is that new companies can take existing code and come up with exciting new solutions very quickly, without the need for massive and long drawn-out research and development programs.

RadeonSI GLAMOR Benchmarks With X.Org Server 1.16

Graphics/Benchmarks
Linux

With X.Org Server 1.16 having landed in Ubuntu 14.10, it's time for some benchmarks comparing the 1.15 and 1.16 releases on Ubuntu while using the GLAMOR 2D acceleration library.

For some basic X.Org 2D benchmarks I tested a Radeon HD 7950 and R7 260X while running various Linux 2D desktop benchmarks on Ubuntu 14.10 with the Linux 3.16 kernel and Mesa 10.4-devel. In testing the two graphics cards, I was using X.Org Server 1.15.1 that was previously found in the Ubuntu Utopic archive and then switched to X.Org Server 1.16.0 with the rebuilt DDX driver packages too.

Why the Convergent Desktop is So Important to Linux

Filed under
GNU
Linux

There is one truth that all the Linux faithful hold near and dear to their hearts -- that Linux is a leader when it comes to innovation. No other platform has been able to stake that claim for such a long period of time. Even when a different platform unveils something new, many times that innovation can be traced back to Linux.

One such technology is the convergent desktop. The idea behind the convergent desktop is simple -- a seamless transition from mobile to desktop (or laptop). This all started, for better or worse, with Ubuntu Edge. The idea behind Ubuntu Edge was brilliant: A high-end smartphone that, when plugged into a dock, would serve as a traditional desktop. Although the project ultimately failed (due to an inability to raise the $32 million dollars necessary to bring Ubuntu Edge to life), the idea stuck and now every platform is in a race to deliver the convergent desktop.

Speed or torque? Linux desktop vs. server distros

Filed under
GNU
Linux
Server

So allow me to clarify: I believe the time has come when a major, dedicated, server-only Linux distribution is needed. This distribution does not maintain any desktop packages or dependencies -- and is not a distro that merely offers a different default package set for desktop and server use cases.

ACPI, kernels and contracts with firmware

Filed under
Linux

This ends up being a pain in the neck in the x86 world, but it could be much worse. Way back in 2008 I wrote something about why the Linux kernel reports itself to firmware as "Windows" but refuses to identify itself as Linux. The short version is that "Linux" doesn't actually identify the behaviour of the kernel in a meaningful way. "Linux" doesn't tell you whether the kernel can deal with buffers being passed when the spec says it should be a package. "Linux" doesn't tell you whether the OS knows how to deal with an HPET. "Linux" doesn't tell you whether the OS can reinitialise graphics hardware.

Choosing an operating system may seem simple but can result in restrictions on what applications you can run, and if not executed properly, can result in slow running services and websites which will not load.

Security

No matter how good the code review process is, or how high the standards for acceptance, applications will always have bugs, says Joanna Rutkowska, founder and CEO of Invisible Things Lab. So will drivers. And filesystems.

“Nobody, not even Google Security Team, can find and patch all those bugs in all the desktop apps we all use,” Rutkowska says in the Q&A interview, below.

Firefox OS media-casting stick strikes Kickstarter gold

The first Firefox OS based media player has arrived on Kickstarter, in the form of a $25 open-spec HDMI stick that supports Chromecast-like content casting. The Matchstick, which has already zoomed past its Kickstarter campaign’s $100,000 funding goal, with 28 days still remaining, was teased back in June by Mozilla developer evangelist Christian Heilmann. The unnamed prototype was billed as an open source HDMI stick that runs Mozilla’s Linux-based Firefox OS and offers casting capabilities. Few details were revealed at the time except that the device used the same DIAL (DIscovery And Launch) media-casting protocol created by Netflix and popularized by Google’s Chromecast. Read more

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more
