The procfs interface does not support NVRAM polling control. So as to
maintain maximum bug-to-bug compatibility, it does not report any masks,
nor does it allow one to manipulate the hot key mask when the firmware
does not support masks at all, even if NVRAM polling is in use.

Note: when NVRAM polling is active, the firmware mask

hotkey_source_mask:
bit mask that selects which hot keys will the driver
poll the NVRAM for. This is auto-detected by the driver
based on the capabilities reported by the ACPI firmware,
but it can be overridden at runtime.
Hot keys whose bits are set in both hotkey_source_mask
and also on hotkey_mask are polled for in NVRAM. Only a
few hot keys are available through CMOS NVRAM polling.
Warning: when in NVRAM mode, the volume up/down/mute
keys are synthesized according to changes in the mixer,
so you have to use volume up or volume down to unmute,
as per the ThinkPad volume mixer user interface. When
in ACPI event mode, volume up/down/mute are reported as
separate events, but this behaviour may be corrected in
future releases of this driver, in which case the
ThinkPad volume mixer user interface semanthics will be
enforced.
hotkey_poll_freq:
frequency in Hz for hot key polling. It must be between
0 and 25 Hz. Polling is only carried out when strictly
needed.
Setting hotkey_poll_freq to zero disables polling, and
will cause hot key presses that require NVRAM polling
to never be reported.
Setting hotkey_poll_freq too low will cause repeated
pressings of the same hot key to be misreported as a
single key press, or to not even be detected at all.
The recommended polling frequency is 10Hz.
hotkey_radio_sw:
if the ThinkPad has a hardware radio switch, this
attribute will read 0 if the switch is in the "radios

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