Seamless transition

Updated: May 06, 2022

As soon as a full driver process is running in a fully operational system, transition takes place from the minidriver to a full driver. This transition is seamless and causes no blackout times. The full driver merely attaches to the device interrupt, which causes the minidriver to be notified that another process is attaching to its interrupt. The minidriver can then gracefully exit, and the full driver continues to run. The full driver has access to any buffered data that the minidriver chooses to store.
