This is a follow-up to a question I asked a couple of days ago, relating to the amdgpu module not being loadable on boot after an Arch upgrade (AMDGPU module fails to load after Arch upgrade: "Cannot allocate memory").

Having read around a bit online, I suspect the issue may be that the GPU microcode is not being loaded on boot. So, I have a double-barrelled question related to this:

1. How can I verify if the microcode for my AMD GPU was loaded on boot or not?

2. If it wasn't, is it possible to load the GPU microcode manually, after boot? Is there a command for that? (I know that won't be a workable long-term solution, but it might help pinpoint where the issue is)
