350 depends on THINKPAD_ACPI
351 default y
352 ---help---
353 Some thinkpad models benefit from NVRAM polling to detect a few of
354 the hot key press events. If you know your ThinkPad model does not
355 need to do NVRAM polling to support any of the hot keys you use,
356 unselecting this option will save about 1kB of memory.
357
358 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
359 unlikely to need NVRAM polling in their latest BIOS versions.
360
361 NVRAM polling can detect at most the following keys: ThinkPad/Access
362 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
363 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
364
365 If you are not sure, say Y here. The driver enables polling only if
366 it is strictly necessary to do so.
