  • Method and apparatus for allocating host memory for a memory-less add-on devices
    Patent number: 8631221
    Abstract: Methods and apparatus for allocating host memory for use by a host channel adapter (HCA) with insufficient on-board memory are disclosed. In one embodiment, a method includes determining when a host memory arrangement which has a host memory updates a system address map associated with the host memory, and obtaining control from a system basic-input-output-system (BIOS) associated with an operating system (OS) of the host memory arrangement when the system address map is updated. The method also includes allocating a first memory block in the host memory using an add-on device after obtaining control from the host memory arrangement. The system address map is updated by the add-on device to indicate that the first memory block has been allocated to the add-on device. Finally, the method includes returning the control to the system BIOS after updating the system address map.
