Abstract
A computer-implemented method for allocating securely memory resources to a platform-independent device driver is described. In one embodiment, a device driver generates a request for memory allocation in terms of an abstract memory address space. The driver forwards the request to the bus manager. An inner class representation of the bus manager is generated and the identity of the driver is determined. The inner class representation handles the request from the device driver using the same procedures as the bus manager, and appears to the driver as the bus manager itself. Thus, a memory request from a platform-independent device driver can be made in a secure manner.
