# acpi\_bus\_scan(9)

Add ACPI device node objects in a given namespace scope.

## NAME

acpi\_bus\_scan - Add ACPI device node objects in a given namespace scope.

## SYNOPSIS

**int acpi\_bus\_scan(acpi\_handle** *handle***);**

## ARGUMENTS

*handle*

Root of the namespace scope to scan.

## DESCRIPTION

Scan a given ACPI tree (probably recently hot-plugged) and create and add found devices.

If no devices were found, -ENODEV is returned, but it does not mean that there has been a real error. There just have been no suitable ACPI objects in the table trunk from which the kernel could create a device and add an appropriate driver.

Must be called under acpi\_scan\_lock.
