APPARATUS, SYSTEM AND METHOD FOR PROVIDING ACCESS TO A DEVICE FUNCTION |
摘要 |
Techniques and mechanisms for providing access to a function with an input/output (I/O) device. In an embodiment, a main memory of a computer system including the I/O device stores a function-context data structure associating a function with a context for an access to the function. The I/O device stores a configuration for the I/O device to provide the function. In another embodiment, the software process exchanges information with the function-context data structure for the access to the function. The I/O device performs a synchronization of the function-context data structure and the configuration data structure with respect to one another, wherein the function-context data structure operates as a register level interface which interfaces the I/O device and the software process with one another. |

1. A input/output (JO) device comprising:
a memory to store a configuration data structure including a configuration for a function; and a coherency engine including circuitry to provide a software process an access to the function, including the coherency engine to perform a synchronization of the function-context data structure and the configuration data structure with respect to one another, wherein the function-context data structure operates as a register level interface which interfaces the I/O device and the software process with one another. |
