Mesa build fails. It complains that it copies llvm-config14.0.6 to the same file.

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 Apparently the virglrenderer branch is obsolete.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?

Regards
