New Chips Give Linux a Hand in Wearables

Filed under
Linux
Gadgets

Aside from the Tizen-based Samsung Gear S2, and a dozen or so Android-based Android Wear watches, Linux has been something of a no-show in the smartwatch market. Most lower-end watches skip the overhead of Linux in favor of simpler RTOS-based devices running on MCUs.

Yet Linux got a boost into wearables this week when Qualcomm, whose Snapdragon chips fuel most Android Wear watches, announced a Snapdragon Wear 1100 system-on-chip for lower-end smartwatches and wearables. The 28nm-fabricated SoC is built around a single Cortex-A7 core that can be clocked to 1.2GHz.

  • DragonBox Pyra Goes Up For Pre-Order

    It's been a while since last hearing anything about the DragonBox Pyra as an open-source gaming handheld system and successor to OpenPandora...

  • Bitcoin is Now Accepted For DragonBox Pyra Pre-orders

    It is always good to see new merchants accepting Bitcoin payments, as it goes to show businesses want to attract an international clientele. DragonBox, a ship based in Germany, recently started accepting Bitcoin payments for their Pyra computer. A neat little device, which packs quite the punch.

  • DragonBox Pyra pre-orders begin (open Source handheld gaming PC)

    The DragonBox Pyra is a portable computer that looks like a cross between a tiny laptop and a Nintendo DX game console… and it kind of works like a cross between those devices as well. It’s got a 5 inch display, a QWERTY keyboard, the Debian Linux operating system that can handle desktop apps as well as games, and physical gaming buttons.

This Android smartphone and barcode reader comes in a 10-oz. package

Filed under
Android
Gadgets

Rugged computer maker Janam Technologies on Wednesday announced the XT2, a 10-oz. rugged device with a 5-in. touchscreen that runs Android 5.0 (Lollipop).

The device could be called a rugged smartphone, since it comes with many smartphone features, including voice. It supports GSM and GPRS radio signals for voice, as well as 4G LTE for data -- with a Chrome browser. But Janam also added in a Zebra barcode-scanning feature, the ability to withstand 5-foot drops and immersion in up to three feet of water.

Instead of referring to it as a smartphone, Janam instead calls the XT2 a rugged touch computer and claims it is the lightest and most rugged in its class. Janam CEO Harry Lerner said it is "as sleek as a smartphone … with the most advanced technologies to meet the diverse needs of virtually any mobile worker."

The developers of the DragonBox Pyra hope to deliver a handheld gaming device this year that runs open source, Linux-based software. Pre-orders opened last year, although the final price (and ship date) haven’t been set yet.

But the final design seems to be coming together. Team leader “Evil Dragon” has posted a video showing an early prototype of a pretty functional-looking DragonBox Pyra.

Graphics: VC4 and AMDVLK Driver

  • VC4 display, VC5 kernel submitted
    For VC5, I renamed the kernel driver to “v3d” and submitted it to the kernel. Daniel Vetter came back right away with a bunch of useful feedback, and next week I’m resolving that feedback and continuing to work on the GMP support. On the vc4 front, I did the investigation of the HDL to determine that the OLED matrix applies before the gamma tables, so we can expose it in the DRM for Android’s color correction. Stefan was also interested in reworking his fencing patches to use syncobjs, so hopefully we can merge those and get DRM HWC support in mainline soon. I also pushed Gustavo’s patch for using the new core DRM infrastructure for async cursor updates. This doesn’t simplify our code much yet, but Boris has a series he’s working on that gets rid of a lot of custom vc4 display code by switching more code over to the new async support.
  • V3D DRM Driver Revised As It Works To Get Into The Mainline Kernel
    Eric Anholt of Broadcom has sent out his revised patches for the "V3D" DRM driver, which up until last week was known as the VC5 DRM driver. As explained last week, the VC5 driver components are being renamed to V3D since it ends up supporting more than just VC5 with Broadcom VC6 hardware already being supported too. Eric is making preparations to get this VideoCore driver into the mainline Linux kernel and he will then also rename the VC5 Gallium3D driver to V3D Gallium3D.
  • AMDVLK Driver Gets Fixed For Rise of the Tomb Raider Using Application Profiles
    With last week's release of Rise of the Tomb Raider on Linux ported by Feral Interactive, when it came to Radeon GPU support for this Vulkan-only Linux game port the Mesa RADV driver was supported while the official AMDVLK driver would lead to GPU hangs. That's now been fixed. With the latest AMDVLK/XGL source code as of today, the GPU hang issue for Rise of the Tomb Raider should now be resolved.

AMD Ryzen 7 2700X Linux Performance Boosted By Updated BIOS/AGESA

With last week's initial launch-day Linux benchmarks of the Ryzen 5 2600X / Ryzen 7 2700X some found the Linux performance to be lower than Windows. While the root cause is undetermined, a BIOS/AGESA update does appear to help the Linux performance significantly at least with the motherboard where I've been doing most of my tests with the Ryzen 7 2700X. Here are the latest benchmark numbers. Read more

GNU: The GNU C Library 2.28 and Guix on Android

  • Glibc 2.28 Upstream Will Build/Run Cleanly On GNU Hurd
    While Linux distributions are still migrating to Glibc 2.27, in the two months since the release changes have continued building up for what will eventually become the GNU C Library 2.28. The Glibc 2.28 work queued thus far isn't nearly as exciting as all the performance optimizations and more introduced with Glibc 2.27, but it's a start. Most notable at this point for Glibc 2.28 is that it will now build and run cleanly on GNU/Hurd without requiring any out-of-tree patches. There has been a ton of Hurd-related commits to Glibc over the past month.
  • Guix on Android!
    Last year I thought to myself: since my phone is just a computer running an operating system called Android (or Replicant!), and that Android is based on a Linux kernel, it's just another foreign distribution I could install GNU Guix on, right? It turned out it was absolutely the case. Today I was reminded on IRC of my attempt last year at installing GNU Guix on my phone. Hence this blog post. I'll try to give you all the knowledge and commands required to install it on your own Android device.
  • GNU Guix Wrangled To Run On Android
    The GNU Guix transactional package manager can be made to run on Android smartphones/tablets, but not without lots of hoops to jump through first.
