Abstract
Described herein is a system for driver execution. A driver is loaded in a first domain with the driver controlling an associated device. In response to a request from the driver, the driver companion is loaded in a second domain different than the first domain, the second domain comprising a secure environment. The driver companion communicates with the associated device. Communications between the driver and the driver companion are managed (e.g., by an operating system framework). In response to a request from the driver, the driver companion is unloaded.
