  • Timer for hardware protection of virtual machine monitor runtime integrity watcher
    Patent number: 8800052
    Abstract: An apparatus and method for hardware protection of a virtual machine monitor (VMM) runtime integrity watcher is described. A set of one or more hardware range registers that protect a contiguous memory space that is to store the VMM runtime integrity watcher. The set of hardware range registers are to protect the VMM runtime integrity watcher from being modified when loaded into the contiguous memory space. The VMM runtime integrity watcher, when executed, performs an integrity check on a VMM during runtime of the VMM. Execution of the VMM runtime integrity watcher is triggered by a timer event generated based on multiple frequency bands.
