CONFIG_INTEL_MEI_PXP:

MEI Support for PXP Services on Intel platforms.

Enables the ME FW services required for PXP support through
I915 display driver of Intel.


That's ... very useless help text. According to
https://www.phoronix.com/scan.php?page=news_item&px=Intel-PXP-Protected-Xe-Path
this is some kind of DRM. Help text should probably say it has to do
with i915 video, and explain the acronyms, and probably its usecases.
