  • xwayland 21.1.2.901
    This is a release candidate for Xwayland 21.1.3.

Most notable change is a fix for the GBM backend to work with the

Unless any major issues turn up, I'm planning to make the final release
in the coming weeks.

  • XWayland 21.1.3 Nears With Support For NVIDIA 495 Driver's GBM - Phoronix

    The release candidate to XWayland 21.1.3 is out today with just a few changes but made significant by support for the NVIDIA 495 series driver GBM code path.

    XWayland 21.1.3 is the next point release to this code that is spun out from the upstream X.Org Server for delivering standalone XWayland releases separate from tagged xorg-server versions. XWayland 21.3. has only a handful of fixes like an XDG_Output memory leak fix, fixed handling of 1-bit pixmaps in GLAMOR, avoiding possible integer overflows on large pixmaps, and other maintenance items.

  • Vulkanised Fall 2021 Material Available - Autodesk Has Begun Using MoltenVK - Phoronix

    Last week was the virtual Vulkanised Fall 2021 event hosted by The Khronos Group. The two-day event was focused on all things Vulkan and for those that missed it all of the slide decks and other material are now available.

    This was a two-day virtual affair focused on the high performance graphics and compute API featuring a current status update around features like ray-tracing and video encode/decode, interesting usages of Vulkan, and related work like Arm's astcenc encoder, HLSL shader compilation, and more.
