| Description: | ||
| This file allows to execute the associated WMI method with the same name. | ||
|
|
||
| To start the execution, write a buffer containing the method arguments | ||
| at file offset 0. Partial writes or writes at a different offset are not | ||
| supported. | ||
|
|
||
| The buffer returned by the WMI method can then be read from the file. | ||
|
|

| See Documentation/wmi/devices/msi-wmi-platform.rst for details. |
