  • Artificial reality system having hardware mutex with process authentication
    Patent number: 11250124
    Abstract: This disclosure describes hardware-based mutexes that employ software process authentication to prevent a software process from releasing the lock of a mutex locked by another software process. For example, systems are described in which a mutex controller receives a request from a process to lock a mutex. The mutex controller locks the mutex, writing a process key and process identifier to one or more hardware registers associated with the mutex. If the mutex controller receives a request to release the lock on the mutex, the mutex controller determines if the key received with the request matches the process key written in the one or more hardware registers of the mutex and, if so, releases the lock on the mutex.
