However, clinfo command is not showing any devices. > Can anyone help with suggestions? > What is showing clinfo? For reference, I've tried locally and it seems to work fine. Following the steps mentioned in the link, I've used the following options in meson `-Dgallium-drivers=vc4,v3d -Dvulkan-drivers=broadcom -Dgallium-rusticl- enable-drivers=v3d -Dgallium-rusticl=true -Dllvm=enabled - Drust_std=2021` I've also exported `RUSTICL_ENABLED=v3d` and ensured `libclc-15` is installed. With all above, `clinfo` exposes the V3D 7.1.7.0 device Cheers. J.A.<o:p></o:p></div></div></div></div></div></div></div></div></div></div></div></body></html>
