  • Snapcraft at Europython 2018
    In July, several members of our advocacy and design teams went to Europython 2018 in Edinburgh. It was a really well-organised event, mixing great speakers from a vibrant community at a great location. The main reason for us to get closer to the Python developer community was to promote Snapcraft as the best way to publish on Linux, for app developers in general, and for Python developers in particular. As well as increasing awareness of Snapcraft, we gained a deeper understanding of the needs of Python developers and made contact with interesting products and engineers.

Graphics: Wayland/Weston, Mesa and AMD

  • Wayland 1.16 / Weston 5.0 RC2 Released To Fix Vulnerabilities
    Two release candidates of Wayland 1.16 / Weston 5.0 were not originally scheduled, but it's been necessitated due to some pressing issues both with Wayland and its reference compositor. Samsung's Derek Foreman issued these "RC2" releases on Friday rather than going straight to the official Wayland 1.16 and Weston 5.0 releases.

  • RAGE & Doom Get Radeon Workarounds In Mesa 18.3-dev
    If you are looking to enjoy id Software's RAGE or Doom VFR games this weekend on Linux via Wine, they should be playing nicer with the latest open-source Mesa graphics driver code. Timothy Arceri at Valve has added a workaround to get RAGE working under Wine with RadeonSI. The workaround is a DRIRC configuration addition for allowing GLSL built-in variable redeclarations. This is enough to get RAGE working with RadeonSI on Mesa Git. Though only RadeonSI is working out currently since the game relies upon the OpenGL compatibility profile mode that is only supported currently by RadeonSI when it comes to the Mesa drivers. Thanks to Valve's developers and others, the OpenGL compatibility profile mode for RadeonSI has matured into great shape these past few months.
  • Adreno 600 Series Support Lands In Mesa 18.3 Gallium3D

Kristian Høgsberg Kristensen of Google's Chrome OS graphics team (yes, Kristian of Wayland and DRI2 fame) has been working on the Gallium3D support for the Adreno 600 series hardware along with Freedreno founder Rob Clark. This A6xx support is being tacked onto the existing Freedreno Gallium3D driver and amounts to just over six thousand lines of new code. Keep in mind this A6xx Freedreno back-end must also be used with the supported MSM DRM driver in the Linux 4.19+ kernel.

Kernel: Linux 4.19 Staging and Greg Kroah-Hartman's Very Many Stable Releases

  • Linux 4.19 Staging Brings EROFS File-System & Gasket Driver Framework
    Following the USB subsystem updates, Greg Kroah-Hartman sent in the kernel's staging area work for the Linux 4.19 merge window. This experimental/testing area of the Linux kernel is adding a new file-system with 4.19: EROFS. EROFS is developed by Huawei for possible Android device use-cases. EROFS stands for the Extendable Read-Only File-System and is developed to address shortcomings in other Linux read-only file-systems. EROFS features compression support and other features, but the on-disk layout format isn't 100% firm yet -- hence going into the staging area.
