+ bool "MSM Shared Memory Driver (SMD)" + help + Support for the shared memory interface between the apps + processor and the baseband processor. Provides access to + the "shared heap", as well as virtual serial channels + used to communicate with various services on the baseband + processor.
It's an an interface from the cpu running Linux, and the other processor that co-exists with the one running Linux. They need to communicate for certain reasons .. I _think_ something like sending a text message is sent by communicating over this interface, or getting the phone to dial a number, along with many other things.
Thats my take on it anyway.
