What are you trying to do with the MEI controller?

The driver module is already available as a module,

$ zgrep INTEL_MEI /proc/config.gz
CONFIG_INTEL_MEI=y
CONFIG_INTEL_MEI_ME=y
CONFIG_INTEL_MEI_TXE=m
CONFIG_INTEL_MEI_GSC=m
CONFIG_INTEL_MEI_HDCP=m
CONFIG_INTEL_MEI_PXP=m
CONFIG_INTEL_MEI_WDT=m

so, im not sure if getting this working is going to solve anything but i've been trying to get another monitor working on my laptop via USB3 or USB-C and it hasnt been working so i thought i'd just try to get everything that driver probe said wasnt working to working and see if it helps.

╭─[email protected] in ~ took 7ms
 ╰─λ zgrep INTEL_MEI /proc/config.gz
CONFIG_INTEL_MEI=m
CONFIG_INTEL_MEI_ME=m
CONFIG_INTEL_MEI_TXE=m
CONFIG_INTEL_MEI_HDCP=m
CONFIG_INTEL_MEI_WDT=m

thats what i got when i ran that. are the first two supposed to be

CONFIG_INTEL_MEI=y CONFIG_INTEL_MEI_ME=y

and if they are how do i go about doing that?

No, they're available as modules for your specific kernel. You can load it with modprobe.

Again, it would be useful to know what you're trying to do so the correct advice can be given.
