222config THINKPAD_ACPI_HOTKEY_POLL
223 bool "Suport NVRAM polling for hot keys"
224 depends on THINKPAD_ACPI
225 default y
226 ---help---
227 Some thinkpad models benefit from NVRAM polling to detect a few of
228 the hot key press events. If you know your ThinkPad model does not
229 need to do NVRAM polling to support any of the hot keys you use,
230 unselecting this option will save about 1kB of memory.
231
232 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
233 unlikely to need NVRAM polling in their latest BIOS versions.
234
235 NVRAM polling can detect at most the following keys: ThinkPad/Access
236 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
237 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
238
239 If you are not sure, say Y here. The driver enables polling only if
240 it is strictly necessary to do so.

1748 * 1. Many of the keys are mapped to KEY_RESERVED for very
1749 * good reasons. Do not change them unless you have deep
1750 * knowledge on the IBM and Lenovo ThinkPad firmware for
1751 * the various ThinkPad models. The driver behaves
1752 * differently for KEY_RESERVED: such keys have their
1753 * hot key mask *unset* in mask_recommended, and also
1754 * in the initial hot key mask programmed into the
1755 * firmware at driver load time, which means the firm-
1756 * ware may react very differently if you change them to
1757 * something else;
1758 *
1759 * 2. You must be subscribed to the linux-thinkpad and
1760 * ibm-acpi-devel mailing lists, and you should read the
1761 * list archives since 2007 if you want to change the
1762 * keymaps. This requirement exists so that you will
1763 * know the past history of problems with the thinkpad-
1764 * acpi driver keymaps, and also that you will be
1765 * listening to any bug reports;
1766 *
1767 * 3. Do not send thinkpad-acpi specific patches directly to
1768 * for merging, *ever*. Send them to the linux-acpi
1769 * mailinglist for comments. Merging is to be done only
1770 * through acpi-test and the ACPI maintainer.
1771 *
1772 * If the above is too much to ask, don't change the keymap.
1773 * Ask the thinkpad-acpi maintainer to do it, instead.
