Abstract
In accordance with certain other techniques, doorbell information is received. A doorbell structure address is decoded from the doorbell information. A first protection domain identifier is determined from the doorbell structure address. A resource context of a data structure is determined from the doorbell information. The resource context at the doorbell address is read to determine a second protection domain identifier. The first protection domain identifier and the second protection domain identifier are compared to determine whether to update the resource context of the doorbell structure.
