Hi Ian.

This is not a bug in vulkan-tools. vulkan-tools correctly reports
initialization failure, as it should.

It is pretty well known fact that HD 7900 series requires switching to
amdgpu from radeontop for Vulkan support.

It is documented on Debian wiki:
https://wiki.debian.org/AtiHowTo#AMDGPU.2FVulkan_on_older_cards

Unless upstream Linux kernel fixes this to make amdgpu a default for
this hardware
(which could happen very soon, after years of waiting!), Debian can't really
(and shouldn't) do much about it.

Please close this bug.
