1 .. SPDX-License-Identifier: GPL-2.0-or-later 2 3 ============== 4 WMI Driver API 5 ============== 6 7 The WMI driver core supports a more modern bus-based interface for interacting 8 with WMI devices, and an older GUID-based interface. The latter interface is 9 considered to be deprecated, so new WMI drivers should generally avoid it since 10 it has some issues with multiple WMI devices and events sharing the same GUIDs 11 and/or notification IDs. The modern bus-based interface instead maps each 12 WMI device to a :c:type:`struct wmi_device <wmi_device>`, so it supports 13 WMI devices sharing GUIDs and/or notification IDs. Drivers can then register 14 a :c:type:`struct wmi_driver <wmi_driver>`, which will be bound to compatible 15 WMI devices by the driver core. 16 17 .. kernel-doc:: include/linux/wmi.h 18 :internal: 19 20 .. kernel-doc:: drivers/platform/x86/wmi.c 21 :export:
