Described are techniques for facilitating communication between device drivers. A device driver is provided that makes at least one call using an application programming interface. The application programming interface facilitates communication between the device driver module and a target code module. The application programming interface provides support for performing the at least one call from a first execution mode associated with the device driver module and a second execution mode associated with the target code module. The application programming interface provides support for user space to user space communication, user space to kernel space communication, kernel space to kernel space communication, and kernel to user space communication. The first execution mode of the device driver module and said second execution mode of the target code module are determined. A communication path between the modules is established in accordance with said first execution mode and said second execution mode.
