Abstract
The disclosure herein describes generating an ordered filter driver list defining a processing order of filter drivers in a device stack for a device. A filter driver level order associated with the device is defined, and a request from an entity is received for an ordered filter driver list. Filter driver data of filter drivers associated with the device is accessed from a data store. The filter driver data includes an identifier and filter driver level of each filter driver. The ordered filter driver list is generated to include the filter driver identifiers of the plurality of filter drivers in an order of the associated filter driver levels in the filter driver level order. The ordered filter driver list is provided to the entity. The use of filter driver levels and an associated order enables accurate, declarative order assignment of filter drivers.
