  • System management memory coherency detection
    Patent number: 11948008
    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.

  • Secure operating modes for computing devices
    Patent number: 11907411
    Abstract: Example computing devices that are enabled to enter secure operating modes are provided. An example computing device includes a main processor to run an operating system enabled to establish communication from an external device to the main processor via a hardware interrupt handler when the external device is connected to the computing device. The computing device further includes a keyboard controller to detect a lock keystroke sequence at a keyboard, and, in response to detecting the lock keystroke sequence, cause the main processor to halt the operating system and to enter a secure operating mode in which communication from the external device to the main processor via the hardware interrupt handler is blocked.
