You need to build mesa, not mesa-native. And please show exact changes you made.

  Also vulkan-drivers is empty in meson generated by bitbake. If I add it 
manually it will complain that llvm is disabled. How would I enable it?

  I think for software vulkan you need to pass in
  -Dvulkan-drivers=swrast when building mesa for the target.

   I asked the author so I assume he would have told me. Apparently the 
virglrenderer branch is obsolete.

   Currently my only changes from poky master are adding vulkan opengl x11 to 
distro features and vulkan-samples vulkan-loader vulkan-tools virglrenderer to 
core image extra install in local.conf.

   I also added virtio-experimental flag to mesa and virglrenderer meson 
recipes.

   I still get ERROR_INCOMPATIBLE_DRIVER when running vulkaninfo.

   What am I missing for Software Mode?

   I would first check whether any of that work in the branch has meanwhile 
landed upstream. The post is from 2021.

   Have you tried the software Vulkan in the guest?

   I try to enable vulkan according to this tutorial

   
https://www.collabora.com/news-and-blog/blog/2021/11/26/venus-on-qemu-enabling-new-virtual-vulkan-driver/

   According to the author the modified qemu branch is still necessary so I 
want to enable that.

   You need to clarify what you want to do exactly. Why can’t you use the 
existing recipe?

   Greetings,

   I want to change the git repo url in order to test the Venus driver. Can 
someone tell me which variable in which recipe I'd have to set?
