  • Wayland's Weston 5.0 Moved Up To An August Release

    Following the recent discussions of moving Wayland's Weston compositor to a 4-month release schedule and possibly doing away with time-based Wayland releases itself, Weston 5.0 will now be coming out in August.

    Feature development on Weston is as busy as ever while Wayland (libwayland) is quite mature and not seeing too much churn. Upstream Wayland developers now appear to be in agreement to carrying out the next Weston release at least on a four-month release cycle.

  • Librem 5 progress report #14

    On the nuts and bolts level, our phone shell (phosh) has seen several usability improvements mostly around the lockscreen. One important change is that the lockscreen unlocking has been switched to PAM to better handle the PIN to lock the device. There have also been some additions to the code to better handle multiple outputs (screens). Also, Libhandy is our “handy” UI library for developing GTK+ apps. There has been a recent addition of an arrows widget (HdyArrows) to indicate swiping direction which will be very useful to many applications, especially the lockscreen. Additionally, libhandy has seen some bug fixes and a slight rework of the keyboard handling support. Since graphics are important, we have added Etnaviv support to weston-simple-dmabuf (a Wayland client to test Linux DMA-BUF protocol implementations). We also extended it’s NV12 format support. It’s being used over here to test wlroot’s linux-dmabuf implementation which we wrote a couple of weeks ago. We’d like to especially thank the wlroots and Weston projects for their code reviews, recommendations, and support.

  • Librem 5 Continues Working On Its Wayland Software Stack, Testing Vibration Motors, Chargers

    Purism has published their latest progress report on the Librem 5 privacy-minded Linux-powered smartphone that they still hope to begin shipping next January.

  • Intel Developers Working On HDCP Content Protection Protocol For Wayland [Ed: This is basically “Linux Vista”. First Web DRM (EME). Now LF sells out as well.]

    With Intel's DRM kernel driver now supporting HDCP for High-bandwidth Digital Content Protection with work done by Intel and Google developers, there is now work underway for allowing HDCP to work in a Wayland-based environment.

    As with the work done on the Direct Rendering Manager side, these Wayland patches aren't enforcing any restrictions on users by itself but is simply making the support available should any applications come along that wish to enforce HDCP usage on the Linux desktop.

  • VFIO Adds Sample Mediated Device Display Drivers

    The VFIO framework that allows exposing direct device access to user-space in a secure, IOMMU-protected fashion is gaining some new sample drivers in Linux 4.18.

Samsung Linux on DeX beta hands-on: do almost everything on your phone

Among the various Linux on Android implementations, Samsung’s Linux on DeX definitely looks the most polished ready to use solution, even if it’s still in beta form. Although it uses a two-year-old version of Ubuntu, there is already a lot that can be done from that. Plus, just like Android users, Linux users can be pretty creative and only time will tell if they’ll be able to use Linux on DeX to make almost any Linux distro work. Read more

A Look At The GCC 9 Performance On Intel Skylake Against GCC 8, LLVM Clang 7/8

With GCC 9 embarking upon its third stage of development where the focus ships to working on bug/regression fixes in preparation for releasing the GCC 9.1 stable compiler likely around the end of Q1'2019, here is a fresh look at the GCC 9 performance with its latest development code as of this week compared to GCC 8.2.0 stable while using an Intel Core i9 7980XE test system running Ubuntu Linux. For good measure are also fresh results from LLVM Clang 7.0 stable as well as LLVM Clang 8.0 SVN for the latest development state of that competing C/C++ open-source compiler. Read more

This under-$6 SBC runs Linux on RISC-V based C-SKY chip
