Abstract
Techniques for associating device drivers via a device tree are described herein. In one embodiment, a device tree having a hierarchical structure is maintained by a kernel of an operating system. The device tree includes device nodes corresponding to devices installed in a computer, including a first node and a second node. An auxiliary driver identifier is encoded within the first node for identifying a second device driver associated with the second node. The auxiliary driver identifier is used by a first device driver associated with the first node to invoke the second device driver to perform a predetermined operation on a device associated with the first node. Other methods and apparatuses are also described.
