System and method for providing adaptive access to a hardware block on a computer system. In one embodiment, a method includes receiving a first access request and a second access request with an access controller, wherein the second access request is received sequentially after the first access request, and the first access request includes a first master identification and the second access request includes a second master identification, determining if the second master identification is equal to the first master identification, providing access to the second access request if the second master identification is equal to the first master identification, wherein the first master identification is associated with one or more hardware block interface values, invalidating the one or more hardware block interface values associated with the first master identification if the second master identification is not equal to the first master identification, and associating the one or more hardware block interface values with the second master identification and a corresponding privilege.
