Stroke and gestures now on Raspberry Pi touch screen

Filed under
Development
Linux
Gadgets

The PiTFT is one of our favourite little things for the Raspberry Pi, making it much more portable than it naturally is and opening it up to many more cool projects than you could do before. The one thing it did lack was proper, modern touch screen controls such as swiping and gesture but this has now been added thanks to Xstroke.

Feasibility of desktop on ARM cpu

Filed under
GNU
Linux
OLPC

Thinkpad X60 is old, Core Duo@1.8GHz, 2GB RAM notebook. But it is still pretty usable desktop machine, as long as Gnome2 is used, number of Chromium tabs does not grow "unreasonable", and development is not attempted there. But eats a bit too much power.

OLPC 1.75 is ARM v7@0.8GHz, .5GB RAM. According to my tests, it should be equivalent to Core Solo@0.43GHz. Would that make an usable desktop?

Open-Source Radeon Performance Boosted By Linux 3.16

Filed under
Graphics/Benchmarks
Linux

Besides the Nouveau driver performance being faster thanks to experimental re-clocking when using the Linux 3.16 kernel, there are also performance improvements to note with some generations of AMD graphics processors.

The changes found within Linux 3.16 to benefit the Radeon DRM graphics performance are the GPU VM optimizations and large PTE support. Separate from this performance-related work for this kernel-side open-source AMD update is also HDMI deep color support, HDMI audio clean-ups, and other bug-fixes.

Performance benchmarks: KVM vs. Xen

Filed under
Graphics/Benchmarks
Linux
Server

After having some interesting discussions last week around KVM and Xen performance improvements over the past years, I decided to do a little research on my own. The last complete set of benchmarks I could find were from the Phoronix Haswell tests in 2013. There were some other benchmarks from 2011 but those were hotly debated due to the Xen patches headed into kernel 3.0.

Raspberry Pi DRM+Gallium3D Driver Makes Great Progress In One Week

Filed under
Graphics/Benchmarks
Linux

Last week Eric Anholt left Intel's Linux graphics driver team to go work for Broadcom developing a VC4 DRM/KMS and Gallium3D driver for the GPU that supports the Raspberry Pi.

Eric ended up making more progress in his first week than he anticipated in starting off this new open-source Linux graphics driver project. He ended up getting his work items done that originally he anticipated would take him about one month. The basic "hack driver" is now working to run triangle code running on a kernel with a relocations-based GEM interface. Thursday he already started on the Broadcom VC4 Gallium3D driver, which in turn is based upon the Freedreno driver for Qualcomm's ARM hardware.

Re-Testing NVIDIA's Threaded OpenGL Optimizations For Linux Gaming

Filed under
Graphics/Benchmarks
Linux

Back in 2012 with the NVIDIA 310 Linux driver series a threaded OpenGL optimization was added to the proprietary graphics driver. When this driver premiered we tested NVIDIA's Linux threaded OpenGL optimizations to mixed results. We're back now re-testing the OpenGL threaded optimizations to see if it makes any more of a difference now with modern Linux games and OpenGL workloads while using the latest 337.25 Linux driver.

NVIDIA's OpenGL threaded optimization feature allows offloading the CPU computational workload to a separate processor thread. This feature is designed to benefit CPU-heavy workloads but can potentially worsen the performance depending upon the game/application's particular OpenGL calls. As a result, the threaded optimization feature remains disabled by default while it's been around for two years. For more information on the threaded optimization feature and how to enable it, see the earlier article.

Russia's Baikal processor will be built around an ARM Cortex A57, which ties into Vladimir Putin's goal, established in 2010, to move all government computers over to Linux - another move that's easy to understand given the OS' open-source and modular nature.

Asus C200 Chromebook review: Long battery life, moderate performance

The Asus C200 Chromebook is a 2.5 pound laptop that offers up to 12 hours of battery life and sells for just $249. It’s not the fastest notebook around, doesn’t have the best screen, and some folks might find Google’s Chrome OS operating system limiting. But there’s a lot to like about this little laptop… especially given the low price.

Security: Uber Sued, Intel ‘Damage Control’, ZDNet FUD, and XFRM Privilege Escalation

  • Uber hit with 2 lawsuits over gigantic 2016 data breach
    In the 48 hours since the explosive revelations that Uber sustained a massive data breach in 2016, two separate proposed class-action lawsuits have been filed in different federal courts across California. The cases allege substantial negligence on Uber’s part: plaintiffs say the company failed to keep safe the data of the affected 50 million customers and 7 million drivers. Uber reportedly paid $100,000 to delete the stolen data and keep news of the breach quiet. On Tuesday, CEO Dara Khosrowshahi wrote: “None of this should have happened, and I will not make excuses for it.”
  • Intel Releases Linux-Compatible Tool For Confirming ME Vulnerabilities [Ed: ‘Damage control’ strategy is to make it look like just a bug.]
    While Intel ME security issues have been talked about for months, confirming fears that have been present about it for years, this week Intel published the SA-00086 security advisory following their own internal review of ME/TXE/SPS components. The impact is someone could crash or cause instability issues, load and execute arbitrary code outside the visibility of the user and operating system, and other possible issues.

gThumb 3.6 GNOME Image Viewer Released with Better Wayland and HiDPI Support

gThumb, the open-source image viewer for the GNOME desktop environment, has been updated this week to version 3.6, a new stable branch that introduces numerous new features and improvements. gThumb 3.6 comes with better support for the next-generation Wayland display server as the built-in video player, color profiles, and application icon received Wayland support. The video player component received a "Loop" button to allow you to loop videos, and there's now support for HiDPI displays. The app also ships with a color picker, a new option to open files in full-screen, a zoom popover that offers different zoom commands and a zoom slider, support for double-click activation, faster image loading, aspect ratio filtering, and the ability to display the description of the color profile in the property view.
