Currently the etnaviv driver does not support Vulkan. Only intel and AMD

and indeed if you run "vulkaninfo" on an etnaviv board:


Vulkan Instance Version: 1.1.73

Cannot create Vulkan instance.
/build/vulkan-E9u7gz/vulkan-1.1.73+dfsg/demos/vulkaninfo.c:812: failed with VK_ERROR_INCOMPATIBLE_DRIVER

So vulkan support is a TODO for etnaviv (used in the Librem-5).
