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. | |

863 | This driver adds support for access to certain system settings |
864 | on "legacy free" Toshiba laptops. These laptops can be recognized by | |
865 | their lack of a BIOS setup menu and APM support. | |
866 | ||
867 | On these machines, all system configuration is handled through the | |
868 | ACPI. This driver is required for access to controls not covered | |
869 | by the general ACPI drivers, such as LCD brightness, video output, | |
870 | etc. | |
871 | ||
872 | This driver differs from the non-ACPI Toshiba laptop driver (located | |
873 | under "Processor type and features") in several aspects. | |
874 | Configuration is accessed by reading and writing text files in the | |
875 | /proc tree instead of by program interface to /dev. Furthermore, no | |
876 | power management functions are exposed, as those are handled by the | |
877 | general ACPI drivers. | |

1270 | This driver provides interfaces to configure and use |
1271 | telemetry for INTEL SoC from APL onwards. It is also | |
1272 | used to get various SoC events and parameters | |
1273 | directly via debugfs files. Various tools may use | |
1274 | this interface for SoC state monitoring. | |
