The Driver Index manages the list of drivers that exist in a Fuchsia system. The Driver Index vends the fuchsia.driver.index.DriverIndex FIDL.
Driver Manager uses the Driver Index to find a Driver to bind to a given Device. Driver Index does this by running all of the Driver bind rules against a given Device and returning the Driver that matches the Device the best.
Driver Index will be used by the Drivers-As-Components effort.
When the Driver Index is complete, it will be built in every product and launched during startup.
Unit tests for the Driver Index are available in the
