Latest Patents
Hank Levy holds a patent for a groundbreaking solution titled "Recovering Device Drivers." This invention introduces a mechanism known as the shadow driver, which acts as an operating system (OS) kernel agent. The shadow driver monitors communication between the OS kernel and the device driver it shadows. In the event of a device driver error, the shadow driver takes over, intercepting and responding to calls from the OS kernel and the failed device driver. This innovative approach ensures that applications and the OS kernel remain isolated from the failure, thereby maintaining application integrity. The initial embodiment of this solution was developed for use with the Linux™ OS and has been tested with multiple device drivers. Results indicate that shadow drivers effectively mask device driver failures, impose minimal performance overhead, require no changes to existing applications and device drivers, and can be implemented with relatively little code.
