Radeon VII (Vega 20) Firmware Support Lands In Linux-Firmware.Git

In addition to needing a recent version of the Linux kernel and Mesa (ideally, Linux 5.0 and Mesa 19.0 if enjoying the very best performance and features) for using a Radeon VII graphics card on Linux, you also need to have the necessary firmware binaries manually installed if not using the Radeon Software for Linux driver package. Those firmware bits are now in the linux-firmware.git repository.
