Is Vulkan supported on AMD Radeon HD 7900 series (TAHITI)? Some
sources I found say it is:

but vulkaninfo just gives me an error despite my having
mesa-vulkan-drivers installed.
On this generation of GPUs, you'd need to use an AMDGPU driver instead of
RadeonSI to get Vulkan Support. You can do that by adding
'radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1
amdgpu.cik_support=1' to your kernel cmdline. vulkaninfo shouldn't output
any errors after doing that.
The default driver for CGN 1.0 cards might be changed to AMDGPU in the
future.
