Abstract
A network interface controller is provided which is shareable by a plurality of operating system domains (OSDs) within their load-store architecture. The controller includes local resources for corresponding to the OSDs, and global resources corresponding to both the OSDs and a network fabric. A method and apparatus is provided for distinguishing between the local and global resources, for purposes of reset and configuration. The controller allows a reset of only those local resources which are associated with the OSD transmitting the reset. Registration logic allows one of the OSDs to register as master, for configuration and reset of global resources.
