  • Methods and apparatus for accessing device memory via a host bus interface
    Patent number: 9442794
    Abstract: In aspects of accessing device memory via a host bus interface, a computing system includes a device that is integrated in the computing system, and the device has device firmware that controls operation of the device. The computing system also includes a device driver that is executable by a processor of the computing system. The device driver is implemented to monitor whether an exchange of control messages between the device driver and the device firmware via a data bus has stalled. In response to determining that the exchange of the control messages has stalled, a debug function of the device firmware is initiated. The debug function is implemented to transfer firmware data from firmware memory to a data bus register of the device, and the device driver can then access the data bus register to obtain the firmware data that is transferred from the firmware memory.
