Cool, you’re going to have to enable Sea Islands (CIK) support for amdgpu. You should just have to add radeon.cik_support=0 amdgpu.cik_support=1 to your kernel parameters. You’re probably using GRUB so to do that you’ll need to run sudo nano /etc/default/grub to edit it’s config file, then add the above to the end of GRUB_CMDLINE_LINUX_DEFAULT (keep it in the quotes, but space seperated from the previous parameter). Then reboot and hopefully Vulkan works!
