22 help
23 This driver adds support for the ACPI-WMI (Windows Management
24 Instrumentation) mapper device (PNP0C14) found on some systems.
25
26 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
27 ACPI firmware to userspace - this is done through various vendor
28 defined methods and data blocks in a PNP0C14 device, which are then
29 made available for userspace to call.
30
31 The implementation of this in Linux currently only exposes this to
32 other kernel space drivers.
33
34 This driver is a required dependency to build the firmware specific
35 drivers needed on many machines, including Acer and HP laptops.
36
37 It is safe to enable this driver even if your DSDT doesn't define
38 any ACPI-WMI devices.

619 default y
620 help
621 Allows the thinkpad_acpi driver to provide an interface to control
622 the various video output ports.
623
624 This feature often won't work well, depending on ThinkPad model,
625 display state, video output devices in use, whether there is a X
626 server running, phase of the moon, and the current mood of
627 Schroedinger's cat. If you can use X.org's RandR to control
628 your ThinkPad's video output ports instead of this feature,
629 don't think twice: do it and say N here to save memory and avoid
630 bad interactions with X.org.
631
632 NOTE: access to this feature is limited to processes with the
633 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
634 where it interacts badly with X.org.

639config THINKPAD_ACPI_HOTKEY_POLL
640 bool "Support NVRAM polling for hot keys"
641 depends on THINKPAD_ACPI
642 default y
643 help
644 Some thinkpad models benefit from NVRAM polling to detect a few of
645 the hot key press events. If you know your ThinkPad model does not
646 need to do NVRAM polling to support any of the hot keys you use,
647 unselecting this option will save about 1kB of memory.
648
649 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
650 unlikely to need NVRAM polling in their latest BIOS versions.
651
652 NVRAM polling can detect at most the following keys: ThinkPad/Access
653 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
654 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

657 it is strictly necessary to do so.

1250 The Primary to Sideband (P2SB) bridge is an interface to some
1251 PCI devices connected through it. In particular, SPI NOR controller
1252 in Intel Apollo Lake SoC is one of such devices.

1254 The main purpose of this library is to unhide P2SB device in case
1255 firmware kept it hidden on some platforms in order to access devices
1256 behind it.
