  • Generic Swapchain implementation
    • regular Vulkan memory buffers if HardwareBuffers aren't available
    • HardwareBuffer-backed VKImages if possible
  • X11
    • Image flipping and color conversion
      • Like EGL, but this time we can't inject code in the shaders, so CPU formatting should be the default
      • It may be possible to run a separate graphics pipeline over the VKImages once they have been submitted to the Swapchain, to convert the format and flipping the X axis (or a compute pipeline could work even better for this workload)
    • Presenting also like EGL, via shared memory Pixmaps
  • Wayland
    • More options for formats, choose one HardwareBuffers and the compositor support if possible
    • Doesn't need to flip the X axis
    • Try to create wl_shm buffers from HardwareBuffer DMABUF fd
    • Use the custom HardwareBuffer protocol if supported instead

Maybe this link will fit here. https://gitlab.freedesktop.org/mesa/vulkan-wsi-layer .

Looks interesting, but only supports Wayland. Maybe I can add X11 support for it.
