Platform Runtime Mechanism Support (ACPI_PRMT) [Y/n/?] (NEW) ?

There is no help available for this option.
Symbol: ACPI_PRMT [=y]
Type : bool
Defined at drivers/acpi/Kconfig:547
Prompt: Platform Runtime Mechanism Support
Depends on: EFI [=y] && X86_64 [=y]
-> Power management and ACPI options

Platform Runtime Mechanism Support (ACPI_PRMT) [Y/n/?] (NEW)

I don't know what that means, there's no help, no nothing. And it is
default y for no apparent reason.

/me looks at the commit message:

Platform Runtime Mechanism (PRM) is a firmware interface that exposes
a set of binary executables that can either be called from the AML
interpreter or device drivers by bypassing the AML interpreter.
This change implements the AML interpreter path.

I'm still unclear whether I need it or not.

Guys, you need to think about your users and to write help text which is
*actually* usable for people who do not deal with ACPI firmware gunk.
