Nexus driver

{{Short description|Type of bus device driver}}

A Nexus driver is a bus device driver that interfaces leaf drivers to a specific I/O bus and provides the low-level integration of this I/O bus.

In some systems, for example Solaris, drivers are organized into a tree structure. A driver that provides services to other drivers below it in the tree is called, in Solaris terminology, a nexus driver. A tree node with no children, a leaf node, is called a leaf driver.{{cite web |title=Writing Device Drivers |url=https://docs.oracle.com/cd/E26502_01/html/E29051/eqbqp.html |website=Oracle.com |access-date=February 14, 2024}}{{cite web |title=Device Tree Components |url=https://shrubbery.net/solaris9ab/SUNWdev/DRIVER/p4.html |website=sun.com |access-date=February 14, 2024}}
