| − | == ibm-acpi - IBM ThinkPad ACPI Extras Driver ==
| + | #REDIRECT [[thinkpad-acpi]] |
| − | | |
| − | This is a Linux ACPI driver for the IBM ThinkPad laptops written by Borislav Deianov. It aims to support various features of these laptops which are accessible through the ACPI framework but not otherwise supported by the generic Linux ACPI drivers. As a kernel module, ibm-acpi works as a bridge to deliver information about certain hardware events like key presses or control the state of certain hardware features by software.

| − | Some of these features are available only when the module is loaded with the <tt>experimental=1</tt> option. To enable it, add the following to {{path|/etc/modprobe.conf}} (or your distribution's equivalent):
| |
| − | options ibm_acpi experimental=1

| |
| − | | |
| − | Included with the Linux kernel since 2.6.10. (Keep in mind, however, that the version included with the official kernel, or with some particular distribution, is not always the latest one.)
| |
| − | | |
| − | Kernel 2.6.14 included version 0.12 (versus version 0.8 in prior kernels).

| |
| − | In development, usable, author does not reply to patch proposals.
| |

| − | === Thermal sensors ===
| |
| − | | |
| − | Eight thermal sensors are exposed at {{path|/proc/acpi/ibm/thermal}}:
| |
| − | | |
| − | # cat /proc/acpi/ibm/thermal;
| |
| − | temperatures: 44 41 33 42 33 -128 30 -128
| |
| − | | |
| − | On some models there are additional sensors at EC offsets 0xC0 to 0xC2, which can be read by parsing {{path|/proc/acpi/ibm/ecdump}}:
| |
| − | | |
| − | # perl -ne 'm/^EC 0xc0: .(..) .(..) .(..) / or next; print hex($1)." ".hex($2)." ".hex($3)."\n"' < /proc/acpi/ibm/ecdump
| |
| − | 40 48 43
| |

| − | The meaning of these sensor varies with models - see [[Thermal sensors]].
