On a MSI B350M MORTAR with Linux 4.18-rc5+ and Debian Sid/unstable the time
noted by initcall_debug for the module amdgpu is 390 ms. The goal is to start
the graphical login manager as quickly as possible and having the graphics
device initialized quickly is therefore required.
Here is a commented excerpt:
