ACPI_BUS_SCAN(9)                  Device drivers infrastructure                  ACPI_BUS_SCAN(9)



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.
