1. the computer system that is used for comprising the one or more processes that can at least one of (i) less relatively restriction kernel mode and (ii) more relatively limited subscriber pattern, work and can makes the hardware adapter that described one or more process communicates by letter with at least one hardware device by communication link, a kind ofly support that relative hardware adapter is that kernel mode is handled and the method for the single realization of the one or more operations that the user model processing is common, this method comprises following action:

  • Be defined as kernel mode processing and user model and handle the common interface title of common at least one operation;

    Provide the kernel mode of described at least one operation that should title is realized;

    Provide the user model of described at least one operation that should title is realized;

    AndFor given process, if given process is the kernel mode process, (i) one or more common interfaces are called be mapped to kernel mode and realize, if and given process is the user model process, (ii) then one or more common interfaces are called and be mapped to user model, wherein, kernel mode is realized comprising than user model and is realized more operation, the operation that it is included and has between kernel normal form realization and the user model realization, and one or more described kernel mode is realized peculiar additional operations.
