==> WARNING: Possibly missing firmware for module: 'foo'

When I create the initramfs, I sometimes see messages like:
==> WARNING: Possibly missing firmware for module: 'xhci_pci'
I get many for different modules.
- What do they mean?
- Should I install the missing firmware? My computer seems to be working fine.
- If I don't want to install, how do I make it not even bother trying to use the firmware for devices I don't care about?

Here's the relevant ArchWiki page.
The gist of it is that most of those warnings are probably for some fairly obscure hardware, and can be just ignored (provided that your system indeed works fine). If you want to fix them (maybe just for the peace of mind), there are packages that contain these missing modules. Installing the correct ones should do away with the warnings. Se the wikipage for details.
