is this just for lavapipe ? would virgl work to utilize the host gpu?

  Looks like it includes the stuff for running OpenGL, OpenCL, Vulkan and VA-API on top of D3D12 as well. Microsoft made their own Mesa builds for this once, but they don't appear to be updating them? https://apps.microsoft.com/detail/9nqpsl29bfff https://apps.microsoft.com/detail/9nqpsl29bfff

    More details: https://devblogs.microsoft.com/directx/announcing-the-opencl-and-opengl-compatibility-pack-for-windows-10-on-arm/ https://devblogs.microsoft.com/directx/announcing-the-opencl... Like Apple, I think Microsoft see OpenGL as a legacy compatibility thing only.

      As does Google, Sony, Nintendo, and even Khronos, version 4.6 doesn't even deserve a red book edition update.

Yeah GL is really legacy. On elf/linux, I have it ONLY for the 32bits steam client which is still hardcoded for GL, x11 and 32bits (and probably a few small GL only games here and there, mistakes, which I would not mind _not_ buying if I had a clean drm/wayland/vulkan3D system). I think I can run dota2 on clean wayland/vulkan3D stack (they are using libSDL3), and basically all roughly recent unity games (and probably UE5.x games which are carefull to build the wayland backend in their binaries). I am sure there is some hick-ups here and there though. The work for "clean" legacy and dying apps is huge: Xwayland with a clean GLX/GL implementation on top of drm/wayland/vulkan3D. When you compare with the technical cost of wayland on drm/vulkan3D (well, there is a still some dependency on c++ abominations in vulkan mesa), motivation is a goner... and who is going to debug and maintain (actually make it work) that ultra-heavy and complex Xwayland/GLX/GL stack on top of drm/wayland/vulkan3D? It is hell. I said all that but I am still running xorg... at least I am writing my own wayland compositor (something that suits me) to move away from native x11.

  XWayland is compartmentalized, and should not make life harder for anyone else in the Wayland world (except the ones spending time maintaining it). And Zink gives us a clean OpenGL implementation on top of Vulkan (so not contributing to complexity in the base stack). I'm fine with a long tail of software requiring XWayland+Zink, and I don't think of them as polluting my system.

    Last time I had a quick look, zink did seem far from being finished, I mean very far away. The main issues for xwayland+zink are the middle ground applications: those which are x11/vulkan3D without wayland support, if I am not mistaken, like shadow of the tombraider, metro exodus games, etc (even though I would not play anymore those games). ohohoh... I am going to ask if valheim has a working/tested wayland backend while I am thinking about it.

      You probably haven't looked at it for a while. It's a conformant OpenGL implementation. Zink is now the default for Nvidia GPUs in Mesa, replacing Nouveau. https://www.collabora.com/news-and-blog/news-and-events/goodbye-nouveau-gl-hello-zink.html https://www.collabora.com/news-and-blog/news-and-events/good...

        Any chance on AMD GPUs? Zink GLX is only for xwayland?
  - ChocolateGod 1y ago
    I think Wayland compositors should start to remove built in Xwayland and rely on tools like xwayland-sattelite for their X compatibility. Making it easy to run a truly X less compositor and moving X to an optional compatibility layer.

Just today I've used this in a Windows 11 QEMU VM to fix rekordbox (it failed to start about 4 out of 5 tries). rekordbox uses Unity with OpenGL for the UI and I guess the devs never tested it on a computer without GPU acceleration. Amazing stuff.
