Abstract
In an example, a system includes a firmware controller to initiate a SM execution mode of the system. The firmware controller scans memory for a process pool tag. The firmware controller compares the process pool tag to a set of operating system process pool tags and detects a coherency discrepancy between the process pool tag and the set of operating system process pool tags. The firmware controller exits the SM execution mode of the system.
