Abstract
Described are techniques for intermodule communication between a first code module and a second code module each executing in user space. A shared memory portion includes storage for one or more commands and is accessible to the first and the second code modules. A first first-in-first-out (FIFO) structure is used for sending a location in the shared memory portion from the first code module to the second code module. A second FIFO structure is used for sending a location in the shared memory portion from the second code module to the first code module. The first code module stores command data for a command at a first location in the shared memory portion. A command is issued from the first code module to the second code module by sending the first location from the first code module to the second code module using the first FIFO structure.
