  • Separation of control and data plane functions in SoC virtualized I/O device
    Patent number: 10817456
    Abstract: An apparatus and method for controlling a device with shared hardware resources to provide separate execution environments for control and data functions are disclosed. A processor may be configured to generate a first request to access control functions of the device in response to execution of a first thread, and generate a second request to access data functions of the device in response to execution of a second thread. A communication unit may send first indicative of the first request and second data indicative of the second request to the device via first and second ports, respectively.
    Type: Grant
    Filed: June 21, 2017
    Date of Patent: October 27, 2020
    Assignee: Oracle International Corporation

  • Validating message-signaled interrupts by tracking interrupt vectors assigned to devices
    Patent number: 8631181
    Abstract: The disclosed embodiments provide a system that validates message-signaled interrupts. During operation, the system receives a message-signaled interrupt from a requesting device. This message-signaled interrupt includes an interrupt vector that identifies an interrupt, and is accompanied by an identification tag that identifies the source of the interrupt. The system uses the interrupt vector to access a stored tag from a tracking mechanism that associates source devices with their assigned interrupt vector(s). The system then compares the identification tag and the stored tag to validate the message-signaled interrupt.
