** Description changed: When booting with secure boot and kernel lockdown is enabled, OpenCL is unable to use my GPU (GeForce RTX 2080 SUPER). Running "clinfo" shows - "Number of platforms 0". If I disable secure boot in my UFEI BIOS, + "Number of platforms 0". If I disable secure boot in my UEFI settings, clinfo shows the details of my GPU as expected.
